CATEGORY 1: WOOD (General)

101 What is the advantage of using Bangkirai Hardwood, rather than the cheaper Coconut wood 
Bangkirai is a Tropical Hardwood. Coconut wood is a softwood. There exist only three wood species in Indonesia which are not susceptible to termite attacks (white ants), these are in order of costs (the highest first): Jati Teak, Iron wood and Bangkirai. Since Bangkirai is the cheapest of the three non-susceptible timbers, but has similar strength, we use this wood for our houses and gazebos. NOTE: Coconut wood is loved by termites. A house built in a termite infested area may be devoured in a nick of time. Refer also to question 403
102 We were informed that Merbau is also safe to termite attacks. Is this correct?
Partly yes and partly no. The part of Merbau which is not susceptible to termite attacks comes from the hearthwood, the inner core of the tree. This is called class I Merbau. The disadvantage is, however, that the price is about 50% higher than the sapwood that surrounds the hearthwood (the outer core of the tree). Reference is also made to Category 4.
103 What is the durability of the wood?
You will find the answer to this question on the page Wood Species.
104 I would like to catch rain water from the roof and store this in a cistern. I would like to use the Iron wood shingles for the roof. Can I safely drink the water collected from the roof that has come in contact with Iron wood?
Iron wood is a non-poisonous type of wood and does not contain any chemical substance that is harmful for human beings. Since Iron wood is extremely durable no chemical preservatives or water repellent sealers need to be applied to maintain durability. As such the wood will retain its genuine natural condition. Nonetheless we advise that a purifier be used to clean the rain water. We advise you always to check with the Authorities whether the use of Iron wood shingles is allowed for rain water catching roofs
105 We have been informed that the Counties in the USA do not recognize some tropical hardwoods. How do you cope with this?
The USA Codes and Requirements for structures are extremely protective as to their own local building materials. Although world-wide any tropical hardwood is    recognized and allowed to be used, the USA does not stand out. The latest Codes and requirements (IBC 2006) still do not deal with tropical hardwood. For many engineers this is a dilemma in how to approach this problem since most tropical hardwoods are 4 to 5 times stronger than any local North American wood. In fact there is no proper solution for this problem until the Code Councils will adapt tropical hardwood as being a building material that is allowed to be used in the USA . Our  experience is that by convincing the County Authorities that tropical hardwood is in average 4 to 5 times stronger than North American construction wood (by prove and evidence obtained from recognized technical papers) the Counties will allow the use.
106 You indicate that both Bangkirai and Iron wood have excellent durability qualities with a life time of over 25 years without any protective coating. Will the wood discolor without such protective coating?
Bangkirai will discolor to a very deep reddish brown color with small occasional light blackish areas. Iron wood will turn into a grayish brown color
107 How thick are the Iron wood shingles
5 mm (3/16”)
108 I have been informed that Bangkirai is prone to cracking. Is that true?
Yes and no. Bangkira is a type of hardwood that is so dense that any change in moisture content will have an effect on the internal interlocking of the wood cells. By  no means we can change that, since it is a natural process. Bangkirai will therefore always show some cracks, however, these are only a fraction of a mm. These cracks will not in any way have influence on the structural integrity, as such, these cracks can be ignored. In some cases, however, Bangkirai may show wider cracks which are caused by air drying. It depends on the depth of the crack whether we will consider changing the part. Normally this is not necessary since the cracks are surface cracks and only a few millimeters deep.
109 How old are the trees used for the timber?
In average 80 to 100 years old
110 My country only allows wood felled at legal and Government controlled plantations to be imported. How do I know that your wood is legal?

The timber that we buy comes either from the Indonesian island of Kalimantan (Bangkirai and Iron wood) or Irian Jaya (Merbau). Even since we are part of Indonesia ( Bali ) we are not allowed to be supplied with logs. This is the first step of the Indonesian Government to crack down on illegal logging, since the logs are checked for legal paperwork at origin. The second step to assure that we receive legal timber is the thorough check by Government Authorities in the harbor of Surabaya , Bali's gateway. If the paperwork is in order they allow the shipment to leave (mostly by road).     

After we have produced a house or gazebo we need to send the drawings + volume calculation and name of supplier to the Ministry of Forestry in Jakarta, who reviews the drawings and checks the supplier. Once in full compliance with the regulations an export license will be issued which is sent to the cargo forwarder. A copy of the document will accompany the shipment.
111 Is there any difference between your standard houses, villas or custom made houses and your ECO cottages?
The simple answer is "not for the full 100%". Our standard houses are being prefabricated and assembled in the same way as the ECO cottages, except that no facilities are provided for solar panels and roof insulation, while the prices for the houses do not include insulation materials for the sidings. However, we can adapt the houses to a full ECO house against a variation order.

CATEGORY 2: WOOD (walls, floors, roofs)  

201 How safe are Iron wood shingle roofs against leaking?
We use the three layer system, while the supporting battens have been cut to exact shape (our little secret) to avoid the shingles from gaping. In addition a layer of aluminum foil is used on top of the plywood base. Refer also to question 205   
202 Can we order a house without roof covering?
Yes. In that case we will only provide the rafters, purlins and battens (if required).
203 We have seen prefab houses of which the floors deflected (bended) significantly when walking over. Can you tell us how your floors have been constructed to avoid this?
It is not a matter of construction. It is a matter of thickness of the board, the intermediate distances of the supporting beams below and the type of wood. We use 25 mm thick boards (1 inch) while the supporting beams do not have a greater center to center distance than 500 mm (1’ – 8”). When Bangkirai, Teak, Iron wood or Merbau is used any person walking over the floor will not notice any effect of deflection
204 What is the difference between a single siding and a double siding and when to use a single board and when to use a double board?
A single siding has a thickness of one board (25 mm). A double siding has one board at each side which is separated by 60 mm thick slats onto which the boards are fixed. A single board is sufficiently effective for simple cottages in tropical areas with a low chance of heavy rain storms. A double board can be insulated and is very effective in areas with significant temperature changes, or areas with heavy rain storms. A double board is also better sound proof compared to a single board, while a double board can hide electrical cables and pipe lines. Alternatively we can supply a single board system with an internal plywood wall which is cheaper.  
205 Can you provide me a detailed sketch of the build-up and structure of the Iron wood shingle roof?
Unfortunately not. This is one of our little secrets. Be assured that our Iron wood roof is 100% water proof, even in high winds. What we can say is that we use the three layer system. Refer also to question 201  
206  I have seen a shingle roof blown away from a prefab structure in a semi hurricane. How is that possible?  
First of all that was not one of our houses. Most probably improper or no hurricane anchors at all were used. A roof is normally not blown away due to wind pressure but due to wind suction. A more likely possibility may be that the roof shingles were not properly attached to the supporting frames which may have caused a failure to one or more shingles blowing away. This creates a local vacuum at the leeward side of the roof, causing more shingles to fail. At the end to the day the whole roof goes.  
207 Can you tell me how your siding boards deal with rain water?  
All exterior siding board are connected by tongue an groove and have a rain water run-off bevel

CATEGORY 3: KILN DRYING

301 Why is the kiln drying of boards so important.
Refer to the page Kiln Drying. 
302 What is the difference between oven dry, kiln dry and air dry
Oven dry and kiln dry is the same except for the wording. The timber is placed in an autoclave and heated by hot air. The wood dries out losing enormous amounts of water which is drained from the autoclave. A volume of 20 m3 of timber may need 6 weeks in the autoclave to dry until 15% water content. Air dry is a process whereas the wood is left in the open for months if not a year to dry out. This process is preferred above kiln drying since this is a forced method causing small cracks in the wood. Refer to Kiln Drying.
303 How much water contains a freshly felled tree?
The “green” wood of freshly felled trees may have a moisture content anywhere in the range of 30% to over 200%, depending on the species

CATEGORY 4: TERMITES (WHITE ANTS)

401 What is the advantage of using Bangkirai Hardwood, rather than the cheaper Coconut wood
Bangkirai is a Tropical Hardwood. Coconut wood is a softwood. There exist only three wood species in Indonesia which are not susceptible to termite attacks (white ants), these are in order of costs (the highest first): Jati Teak, Iron wood and Bangkirai. Since Bangkirai is the cheapest of the three non-susceptible timbers, but has similar strength, we use this wood for our houses and gazebos. NOTE: Coconut wood is loved by termites. A house built in a termite infested area may be devoured in a nick of time.
402 We were informed that Merbau is also safe to termite attacks. Is this correct?
Partly yes and partly no. The part of Merbau which is not susceptible to termite attacks comes from the hearthwood, the inner core of the tree. This is called class I Merbau. The disadvantage is, however, that the price is about 50% higher than the sapwood that surrounds the hearthwood (the outer core of the tree). Refer also to question 403.
403 We have heard that in some occasions termites had attacked Bangkirai, while this wood is not susceptible to termite attacks. How is that possible?
Bangkirai comes in different classes. It would be impossible to select all class “A” Bangkirai wood (heartwood only), as this will significantly increase the price (to almost double). The Bangkirai wood that we use is a mix of class “A” and “B”. A termite may attack class “B” Bangkirai, however, the good news is that it will only be able to devour something from the surface (not more than a millimeter or two). Due to the extreme hardness of Bangkirai a termite will not be able to dig deeper into the wood. If it happens it will be closest to the foundation, as such you will not even notice it. Apart from that it will not at all affect the structural safety of your house.

CATEGORY 5: FOUNDATION

501 Is the foundation included in the design?
No, but we are well able to advise you which type of foundation is required. See also question 502 and 503
502 We have been informed that it is not allowed in the USA to have a wooden column cast in concrete. How do we fix the wooden columns to the concrete foundation?
You need to use Simpson anchors, which are available all over the USA . We will specify the type that you need. Alternatively we can supply similar anchors made in Bali   
503 What will be the dimensions for the concrete footings?
We are unable to answer this question, since this depends on the strength of the subsoil. A weak subsoil layer requires a wide square footing, while a foundation on top of a firm sand layer may be reduced to only 300 x 300 mm (1 ft x 1 ft), or even smaller. You need a local engineer to verify the foundation based on the column reaction forces that we will provide.

CATEGORY 6: PREFABRICATION, RE-ASSEMBLY AND RE-ASSEMBLY TIME)

601 Is it possible to re-assemble the house by your crew at our place?
Yes, we have a team available that can do that. You may contact us for a quotation
602 How many persons are required to assemble a house?
That mainly depends on how fast you would like to erect it. In principle a few persons can do the job, but this may take some months for a large house. You may add people as much as you like, until the saturation point is reached (the point where adding persons will slow down the process). It is advised that at least a few persons have some experience with Do It Yourself. 
603 How do I assemble a two storey house?
We will inform you via the assembly manual how and where you need to make temporary stability bracings and a scaffolding.
604 How long will be the lead time for a house?
Such depends whether you order one of our standard designs or whether we need to make a tailor made design. We are unable to start any prefabrication if we do not have a design available. Prefabrication requires shop drawings (detailed drawings that show how to cut and profile each an every part). Such drawings can only be prepared after a conceptual and basic design is available. In broad lines the lead time can be reduced with some 6 to 8 weeks if a standard model is chosen. The transfer shipping time is in average 6 weeks. Prefabrication time depends on the size of the house.
605 Can you fabricate a house in accordance with our drawings?
Our team of architects and engineers is well able to deal with your requirements. It depends on the magnitude of design work that we need to undertake to enable us to prefabricate the house. In such case we strictly apply our
606 I am a total layman when it comes to DIY. As such I need people to help me re-assembling the house. Do you provide a team that can do that?
Yes, we can outsource a full team or a smaller team to assist you that will re-assemble the house for you. 
607 How much will it cost me to have your people re-assembled the house?

A foreman will cost USD. 9.50 per day. A 1st class carpenter will cost USD. 7.80 per day and a junior carpenter will cost USD. 5.80 per day (as per May 01, 2007, subject to change). On top of that you need to provide economy class return air tickets and simple low cost board and lodging.

The daily rates are based on price level February 2007 and are subject to change.

608 What is included in the kit?
The kit contains all the supporting beams, floor and siding boards, rafters, purlins, slats, battens, roof covering, standard doors and standard windows with brass hardware, all connecting bolts (galvanized steel) and copper screws, a re-assembly manual comprising a part with a full detailed description for the re-assembly and a part showing the pictures made during pre-assembly.
609 How do I know that I would not be left with a disordered mountain of wood after I have emptied the container?
All matching parts are packed together in separate batches. Example: we will pack all floor boards together in sequential order. For instance batch 1 will show an indication “Floor boards 1 thru 20“, batch 2 will be indicated with “Floor boards 21 thru 40”, etc. In the same way the beams and other parts will be packed. The only thing you need to do when emptying the container is storing the packs together with their batch name, thus, floor boards together, siding boards together, main ground floor beams together, etc., etc.
610 How do I know where to place the nails for floors and sidings etc?
We do not use one nail. All connections are fixed by means of bolts or screws. The screw holes are indicated. You only need to drill thru these screw holes a few cm into the back supports and fix the screw. The bolts only need to be placed and tightened. 
611 Do I need to cover the house during re-assembly against rain and sun?
As long as the flooring and/or siding boards have not yet been installed this is not necessary. In the event that boards have not been treated with a protective coating it is highly recommended that a cover be installed from canvas or otherwise once the boards will be installed. The boards have been kiln dried and thus are extremely sensitive for sucking up moist and water. In the event that the boards have been treated with polyurethane stain it is not necessary to cover the house.
612 Would it be possible to later dismantle the house and re-build it elsewhere?
 Without a problem

CATEGORY 7: SHIPPING, PACKING AND CONTAINER SPACE

701 What is fumigation and why is it required?
Fumigation is the process in which gas is used to kill any living creature that may hide in the container. This not only holds for spiders, ants, beetles, mice, rats, etc., but also for mildew, seeding grass (for thatch), borers, and other nuisance. In almost all countries in the world fumigation at the port of embarkation is a prerequisite. Thatch need to be fumigated two times, viz; one time with Ethylene Oxide and one time with Methyl Bromide. All wood parts need to be fumigated with Methyl Bromide only. See also question 1704
702 How many containers do I need to ship my house?

That differs from house to house and depends on the total net volume of wood to be shipped. Shipments can be done with either 20 ft, 40 ft or 40 ft high cube containers.

A basic volume can only be provided if we know which of our standard houses you are interested in. For custom or tailor made houses we cannot calculate the basic volume until we have made a conceptual design. In addition the weight may be governing. Bangkirai wood is very heavy (900 kg/m3). You may need to ship in 2 or more containers if the weigh is over 23 tons.

703 What if some parts are broken during shipment?
Apart from the fact that we are not responsible for broken parts caused during shipment we supply a number of extra beams and boards in the event that some repair works need to be done at your end.
704 Do I need to insure the shipment, and if so how much will that cost?
You are free to decide whether you want to insure the shipment or not. The costs will be 2% of the declared value on the Pro Forma invoice.
705 How will the prefab parts be packed?
That depends on the cargo forwarder. We do not pack. The cargo forwarder collects the goods at our yard, transports it by trucks to their facilities, pack it and stuff the container. Our responsibility ends at the moment the cargo forwarder loads the goods into their trucks.
706 Can we choose our own cargo forwarder, and if so, what will be the procedure?
You may choose your own cargo forwarder. Just log on to internet and search for “ Bali cargo forwarder”
707 Can you provide me the shipping costs to <destination>i

That is virtually impossible. We only fabricate and do not ship. We have a close working relationship with a Bali cargo forwarder who will be able to provide the actual shipping costs, based on our estimated volume. Click Sipping Costs for a broad overview of the cost for a container to be shipped to <destination>

CATEGORY 8: PRICES AND TAXES

801 Are your prices FOB? 
No, all our prices are ex. factory. We do not ship ourselves, instead we have a working relationship with two Bali cargo forwarders. We can ask them for a quotation however you can also assign your own cargo forwarder. In any case, however, the cargo forwarder needs to collect the goods at our yard.
802 What is the average square feet price of a house?

That is not exactly to define. It depends on the type of houses and whether this house is a standard type or a custom made house. It also depends on the shipping costs which vary significantly. In general you may reckon on € 29/sqft up to € 33/sqft, ex factory. Price level: February 2007 and subject to change without prior notice.

803 Can I pay in another currency than Euro
Yes, but we will use the conversion rate issued by the Bank of Indonesia, while we will add a percentage of 1.5% to the invoice for extra bank charges.
804 Do we need to pay export taxes? 
No, the export of prefabricated houses is exempted from export tax. You only pay an endorsement fee and a BRIK retribution, which is some € 300 per each container and is used for reforestation. 
805 Are your prices negotiable?
Unfortunately not.
806 What is included in the price?

CATEGORY 9: HURRICANES AND EARTHQUAKES

901 Is the house designed such that it can withstand hurricane force winds and/.or earthquakes?
Since our houses are being exported world wide we need to keep the design a simple as possible. A hurricane or earthquake proof house which is exported to a non hurricane or earthquake area will be too expensive for that purpose. However, in the event that a house needs to be built in such a specific area we will adapt and modify the design as to comply with the local regulations. We normally apply the IBC 2006 (International Building Code), the IRC 2006 (International Residence Code) and the ASCE/SEI 7-05 for our structural calculations. In most cases the structure needs to be beefed up and hurricane anchors installed and/or earthquake-safe measures taken. For complicated structures we use our 3-Dimnensional STAAD-III Pro finite element computer program

CATEGORY 10: STRUCTURAL ISSUES

1001 Do you rubber stamp the drawings?
Yes, we can, but we are not allowed to. None of our structural engineers or architects have a PE license (only required for the United States ). However, we have a close relationship with Professor David Rockwood from the University of Hawaii at Manoa, who is able to assist individuals in Hawaii to refine designs for local code compliance and obtain building permits.
1002 What is our guarantee once you have supplied the house?
Your guarantee is our 40 years of world wide experience in design and construction. If we would be able to obtain a third party liability insurance for each house that we export (for example thru Lloyds; in London ) the house will become so expensive that it would be useless to continue this business. Nonetheless we cherish our clients and if there should be a problem which is clearly a design error or a fabrication error we will certainly do everything in our power to help and advise you.
1003 Is the foundation included in the design?
No, but we are well able to advise you which type of foundation is required. See also question 502 and 503 in Category 5.
1004 We have seen prefab houses of which the floors deflected (bended) significantly when walking over. Can you tell us how your floors have been constructed to avoid this?
It is not a matter of construction. It is a matter of thickness of the board, the intermediate distances of the supporting beams below and the type of wood. We use 25 mm thick boards (1 inch) while the supporting beams do not have a greater center to center distance than 500 mm (1’ – 8”). When Bangkirai, Teak, Iron wood or Merbau is used any person walking over the floor will not notice any effect of deflection

Our experience is that by convincing the County Authorities that tropical hardwood is in average 4 to 5 times stronger than North American construction wood (by prove and evidence) the Counties will allow the use.
1007 Do you guarantee that my wooden house will still be standing after a hurricane?

Unfortunately not. We cannot fight against the power of nature. We can significantly reduce the risk but we cannot 100% guarantee that a house will not have any damage after a hurricane. Hurricane Katrina may have proven this.  

1008 Is it true that after a year or so, connecting bolts may need to be re-tightened?

Yes, depending on the level of humidity in your area. If you live in an area with low humidity and changing temperatures from hot to cold between the seasons it may indeed be necessary that bolts be re-tightened after a certain period. The moisture content of wood changes with changing humidity. This may cause some contraction or expansion which is called the breathing effect. This breathing may loosen the bolts a bit. Though not dangerous it is advised to re-tighten the bolts until the wood finds its equilibrium and will stop having an effect on the bolted connections.

1304 Do you supply windows with insulated glass panes? 
Yes, we have many types available  
1305 I would like to catch rain water from the roof and store this in a cistern. I would like to use the Iron wood shingles for the roof. Can I safely drink the water collected from the roof that has come in contact with Iron wood?
Iron wood is a non-poisonous type of wood and does not contain any chemical substance that is harmful for human beings. Since Iron wood is extremely durable no chemical preservatives or water repellent sealers need to be applied to maintain durability. As such the wood will retain its genuine natural condition. Nonetheless we advise that a purifier be used to clean the rain water. We advise you always to check with the Authorities whether the use of Iron wood shingles is allowed for rain water catching roofs.  
1306 I would like to tile the bathroom and toilet with ceramic. Is that possible over wood?
Without a problem, provided you apply the following method in the following sequence of installation: water tight membrane, metal lath, scratch coat, mortar bed, bond coat, ceramic tile. 
1307 Is there any difference between your standard houses, villas or custom made houses and your ECO cottages?
The simple answer is "not for the full 100%". Our standard houses are being prefabricated and assembled in the same way as the ECO cottages, except that no facilities are provided for solar panels and roof insulation, while the prices for the houses do not include insulation materials for the sidings. However, we can adapt the houses to a full ECO house against a variation order.

CATEGORY 16: WOOD FINISHING

1601 Do we need to treat the wood with typical paint that prevents the wood from catching fire?
You may do that, but it will disguise the beauty of the wood. In fact, when a wooden building catches fire it will remain in tact far longer than a steel building which will collapse soon after the fire is wide spread. As a result there will be much more time to distinguish the fire for a wooden building compared to a steel building
1602 What is the difference between French polishing and Polyurethane stain?
French polishing is a mix of Shellac and alcohol and cannot be used for external finishing, since it does not protect against ultra violet light and has low resistance against water. Polyurethane stain has an anti-ultra violet filter and is also a heavy duty coat. Polyurethane stain has excellent resistance against rain, sun, chemicals, scrubbing, solvents, impact and abrasion
1603 I live close to the Ocean. I have very bad experiences with corrosion due to constant the salty spray. How effective is your finishing in regard to this?
The use of Polyurethane stain solves the problem of salty spray attacking the underlying wood. Moreover, Bangkirai has an extremely good resistance against salt. The life time will not be reduced when a Polyurethane stain is applied.  
1604 Do you use a different type of Polyurethane stain for the exterior walls and the floors?
Yes, the floors are treated with a fast drying Polyurethane stain
1605 Can you tell me what type of finishing I should use for my wooden house?
Polyurethane stain for the exterior walls, fast drying polyurethane for the floors and a choice between French polishing for the interior walls, columns, etc or Polyurethane stain. French polishing is advised if you would brighten the tone of the wood grain with a beautiful satin finish appearance.
1606 What is Polyurethane stain?
Polyurethane is an all-in wood finish that combines the durability of a satin Polyurethane varnish with the warm and rich colors of a stain. A range of popular ready-mixed colors is available.    
1607 Does your standard protective coatings contain any lead?
Polyurethane does not contain any lead and/or mercury and has no photochemically reactive solvents.
1608 What do I need to do to touch up a part or parts of the wood which may have become damaged during re-assembly?
We provide you a free of charge tin of Polyurethane stain and some Shellac flakes to mix with alcohol to touch up the French polishing (if applicable).
1609 Can I do a French polishing treatment by myself?
Yes, indeed. For instructions click French Polishing.
1610 Can I later change the type of finishing with Polyurethane after I applied a French polishing?
No, definitely not.
1611 Would it be possible that I change the finishing into a latex based paint?
Yes, no problem

CATEGORY 17: THATCH

1701 Why does Hawaii not allow thatch to be imported?   
Each County in Hawaii has imposed strict regulations as to the import of thatch (dried alang-alang or any other type of grass). The main reason is that the authorities want to avoid at each price that any foreign creature enter the islands as well as to avoid that mildew and other pests have a chance to grow. Notwithstanding the fact that proper fumigation will kill all the insects and pests, any thatch that is to be imported will immediately be destroyed whereas the costs will be borne by the owner. However, in some cases a County will issue a special license to import thatch. Such license can only be obtained for developing projects which benefit the islands (example: Kauai may issue a license for thatched roofs for resort projects).
1702 How long will my thatch roof last? 
That depends on the environment. Thatch loves hot sunny weather and sometimes a rain shower to keep it moist. In hot arid areas it is advised to regularly spray the roof with water as to avoid that the thatch starts deteriorating too fast resulting the thatch to dusting and powdering. If not watered such roofs may not last longer than 5 years. In tropical areas with a high humidity and regular showers the thatch feels best and may last 10 to 15 years. In areas with constant high winds, like trade winds, it is not advised to use thatch.
1703 How is it possible that one roof with thatch is leaking while another roof with similar thatch does not?
This has to do with the number of layers of thatch per meter run. In average the distance between thatch panels is 6 to 8 cm. Depending on the pitch of the roof this may be sufficient, however, when the roof pitch is less than 30 deg. thatch panels need to be installed as tightly as possible against each other. This will result in a much ticker thatch covering and thus far better water proof.    
1704 Why must thatch be fumigated? 
Thatch is a natural material (dried Kunai brass) which contains a lot of insects, dirt, small debris, mildew, seeds, etc. Thatch loaded into a container will contain some or all of these pests. Countries want to avoid at each price that such pests have a change to develop or grow, creating a nuisance and/or havoc on its territory. Prior to shipment the container is therefore fumigated. Refer to question 701

CATEGORY 21: FUMIGATION

2101 What is fumigation and why is it required?
Fumigation is the process in which gas is used to kill any living creature that may hide in the container. This not only holds for spiders, ants, beetles, mice, rats, etc., but also for mildew, seeding grass (for thatch), borers, and other nuisance. In almost all countries in the world fumigation at the port of embarkation is a prerequisite. Thatch need to be fumigated two times, viz; one time with Ethylene Oxide and one time with Methyl Bromide. All wood parts need to be fumigated with Methyl Bromide only. 
2102 Why must thatch be fumigated? 
Thatch is a natural material (dried Kunai brass) which contains a lot of insects, dirt, small debris, mildew, seeds, etc. Thatch loaded into a container will contain some or all of these pests. Countries want to avoid at each price that such pests have a change to develop or grow, creating a nuisance and/or havoc on its territory. Prior to shipment the container is therefore fumigated.   
2103 What is an ETO certificate? 
This is a Certificate that many countries require to be submitted with a shipment containing thatch. This Certificate provides prove and evidence that the thatch has been fumigated with both Ethylene Oxide and Methyl Bromide.  
2104 Do I need to pay for fumigation while my shipment does not contain thatch but just wood? 
Yes, fumigation is mandatory. In the case of the container containing just wood fumigation with Ethylene Oxide is required.
 

NOTE: Hawaii does not allow thatch to be imported, while Australia is extremely strict in processing an import license for thatch. They only allow Australian Government approved companies to carry out fumigation in the country of origin.
