The Fumigation Certificate: When a China Shipment Needs One for Bangladesh

A fumigation certificate is a short document stating that a shipment, or the wood used to pack it, was treated with a fumigant such as methyl bromide or phosphine for a set exposure period, on a given date, by a licensed provider. Bangladesh authorities ask for it on specific categories of import to stop live insects, larvae and fungal material entering with the cargo. Importers often confuse it with the ISPM 15 stamp on pallets, or assume it is never needed for general merchandise, and both mistakes lead to a shipment sitting at the port while treatment is arranged locally. This guide explains when the certificate is required, what it must contain, and how it differs from ISPM 15. It complements our notes on ISPM 15 wood packaging and the plant quarantine certificate.

Fumigation certificate versus the ISPM 15 stamp

These solve the same problem, pests in wood, but in different ways and with different proof. ISPM 15 is a treatment standard for solid wood packaging material: pallets, crates, dunnage and bracing. Compliant wood is heat treated or fumigated and then branded with the wheat-ear mark, a country code, a unique producer number and the treatment code. The stamp on the wood is the proof; no separate certificate travels with a standard shipment. A fumigation certificate, by contrast, is a paper record of a fumigation event. It is used when the treatment proof has to be a document rather than a mark: when the goods themselves are fumigated, when the packing is non-standard, or when a Bangladesh authority or the letter of credit specifically calls for a certificate. A shipment can need ISPM 15 compliant pallets and a fumigation certificate for the contents at the same time.

When Bangladesh asks for a fumigation certificate

It is not required for every container. The common triggers are:

• Plant-origin goods handled by the Plant Quarantine Wing, such as raw agricultural produce, seeds, grains, dried plant material, jute and some timber products. These usually need a phytosanitary certificate from China and may need fumigation on arrival or proof of fumigation before shipment.
• Second-hand machinery and used goods, where soil, plant debris and pests can travel in crevices. Inspectors frequently order fumigation for used equipment.
• Non-standard wooden packing that does not carry a valid ISPM 15 mark, or bamboo and other plant-based packing and filling material.
• Letter of credit or contract terms that list a fumigation certificate among the required documents. If it is in the credit, the bank will not settle without it, regardless of what customs asks.
• Cargo found with live infestation at examination, which leads to a mandatory treatment order before release, at the importer cost.

If your goods are ordinary manufactured items, boxed in cartons on ISPM 15 stamped pallets, you generally do not need a fumigation certificate. The risk is assuming that and being wrong about the wood, or about a plant-based component you did not think of.

What a valid fumigation certificate contains

An officer checks the certificate for internal consistency and against the rest of your documents. It should show:

• Name and licence details of the fumigation company, and the treatment provider accreditation.
• Fumigant used, for example methyl bromide, and the dosage rate.
• Date of fumigation, duration of exposure, and the ambient temperature during treatment.
• Description and quantity of the goods or packing treated, matching the packing list.
• Container numbers and seal numbers where the treatment was done in the container.
• Port of loading and destination, and the consignee.
• Place of treatment and a statement that the treatment meets the required standard.

Two failure modes are common. First, the fumigation date is after the bill of lading date, which is impossible if the cargo was treated before loading, and the officer will notice. Second, the quantity or container number does not match the shipping documents. Check both before the vessel sails, because a corrected certificate is easy to obtain in China and nearly impossible to obtain cleanly after arrival.

Methyl bromide, timing and the practical constraints

Methyl bromide is still the workhorse fumigant for export treatment because it acts fast, but it is being phased down under the Montreal Protocol for environmental reasons, and some treatment has moved to phosphine, which needs a longer exposure time, often several days. That matters for your schedule: if fumigation is required and only phosphine is available, build the extra days into the production and shipping plan rather than discovering the delay at the booking stage. Fumigation also cannot be done on a loaded reefer running in fresh-air mode, and some fumigants are unsuitable for foodstuffs, so the treatment method has to suit the cargo.

Getting it wrong at the port

If your shipment needs a fumigation certificate and arrives without one, the usual outcome is a hold, an inspection referral, and an order to fumigate at a licensed facility near the port before release. You pay the treatment, the extra handling and storage, and any demurrage and detention that accrues while it is sorted out. For used machinery this can add a week. The certificate that would have prevented all of it costs a modest fee in China and adds no time if it is arranged during production.

How we keep shipments clear of this

DE International checks at booking whether your goods, their components or their packing trigger a fumigation or phytosanitary requirement for Bangladesh, arranges pre-shipment treatment with a licensed provider in China when it is needed, and checks the certificate dates, quantities and container numbers against the bill of lading and packing list before the vessel departs. For used equipment and any plant-origin cargo we assume treatment is needed until proven otherwise. Tell us what you are importing and we will confirm which certificates your shipment must carry.

Fumigation versus other treatment options

Fumigation is not the only way to satisfy a pest requirement, and it is not always the best one for your cargo. The main alternatives:

• Heat treatment. For wood packaging, kiln or chamber heating to a core temperature for a set time is an accepted ISPM 15 method and leaves no chemical residue. Many Chinese pallet suppliers offer heat-treated stamped wood as standard; specifying it removes the wood question entirely.
• Plastic or metal packaging. Switching from wooden crates to plywood that is exempt, moulded plastic, or steel frames sidesteps the solid-wood rule, though it can raise packing cost and weight.
• Irradiation or cold treatment. Used for some plant-origin commodities rather than general cargo, and only where the destination authority recognises the method.

For finished manufactured goods, the cleanest path is usually heat-treated stamped pallets plus cartons, so no fumigation certificate is needed at all. Fumigation earns its place for used machinery, for genuinely plant-based cargo and packing, and where a letter of credit or a Bangladesh authority names the certificate specifically. Decide the packing method at the order stage with the destination rule in mind, rather than discovering at the port that the wood under your cartons has no valid mark.
