ISPM 15 Wood Packaging: Pet Import Rules | JustForPetStore

Wood pallets, crates and dunnage carrying pet products into the United States must be debarked, heat-treated or fumigated, and stamped with the ISPM 15 mark, or the shipment can be refused entry or ordered reexported. Per APHIS, the importer is the party responsible, not the overseas factory. Put the requirement in your purchase order and verify the stamp before loading.

What is ISPM 15 and who enforces it in the United States?

ISPM 15 is International Standards for Phytosanitary Measures No. 15, the standard that governs wood packaging material moving in international trade. In the United States it is enforced by USDA APHIS together with U.S. Customs and Border Protection, and the domestic rule sits in 7 CFR 319.40. The purpose is narrow and practical: stop wood-boring pests from arriving inside pallets and crates.

Per APHIS, wood packaging material entering or transiting the United States must be pest-free, debarked, heat-treated or fumigated, and marked with an ISPM 15 logo certifying appropriate treatment. Shipments containing noncompliant wood packaging will not be allowed to enter the country.

For a small importer, the important consequence is that this rule is independent of your product. A perfectly documented shipment of dog toys sitting on one untreated pallet is still a shipment that does not clear.

What counts as regulated wood packaging material?

The list is broader than pallets. APHIS names pallets, pallet collars and skids, containers, crates, boxes, cases and bins, reels, drums and load boards, and dunnage. Dunnage is the loose wood used to brace or wedge cargo inside a container, and it is the item most often missed because nobody thinks of it as packaging.

Per the International Plant Protection Convention, ISPM 15 covers wood packaging made from raw wood and includes dunnage, while excluding wood packaging made from wood processed in such a way that it is free from pests, with plywood given as the example. That exclusion is why plywood crates and engineered-wood cases usually travel without a treatment mark.

The test is the material, not the shape. Ask what the wood is, how thick it is, and whether it was manufactured with glue, heat and pressure. If the answer is raw solid wood, assume it is regulated until your broker tells you otherwise.

Which treatments are accepted?

Two treatments are recognized in the standard: heat treatment, abbreviated HT, and methyl bromide fumigation, abbreviated MB. Under 7 CFR 319.40-3, regulated wood packaging may be imported under a general permit only if it has been treated in accordance with 7 CFR part 305, which is the APHIS treatment manual, and marked as required.

Debarking sits alongside treatment rather than inside it. APHIS requires the wood to be pest-free and debarked as a separate condition, so a pallet that carries bark can be rejected even if the treatment stamp is present.

From a buyer’s point of view, HT is the safer ask. It leaves no residue question, it is the most widely available treatment, and it is what most accredited producers in major exporting countries run as standard. If a supplier offers MB, treat it as a flag worth checking rather than an automatic problem.

What must the ISPM 15 mark show?

Four elements, and all four have to be there. Per APHIS, inspectors look for the official mark, which includes the IPPC logo, the two-letter country code, a unique facility number within that country, and the treatment type, either HT for heat treatment or MB for methyl bromide.

The regulation adds detail worth quoting to your supplier. Under 7 CFR 319.40-3(b)(2), the mark must be in a visible location on each article, preferably on at least two opposite sides, and it must be legible and permanent. It must be approved by the International Plant Protection Convention, and the number must be assigned by the national plant protection agency of the producing country to that specific producer.

That last clause is what catches counterfeit stamps. A block of numbers that is not traceable to an accredited producer is not a mark, it is ink. APHIS publishes a noncompliant wood packaging dashboard it calls “Buyer Beware” specifically because some companies pass off untreated wood as compliant.

Who is legally responsible for compliance?

The importer. APHIS addresses the requirement to importers directly: as an importer, you must ensure that all wood packaging material entering or transiting the United States is pest-free, debarked, treated and marked. Your supplier’s assurance does not transfer that duty, and a broker filing the entry does not absorb it either.

This matters commercially because the cost of failure lands on your side of the transaction. Detention, reexport, demurrage and the re-delivery cost of a refused container are yours, and the retail calendar does not move for them. A container of dog feeding supplies that misses a seasonal window because of a pallet stamp has cost you far more than the pallet.

So treat compliance as a term of purchase rather than a hope. If your factory controls the packaging, the factory controls your clearance, which means the requirement belongs in the contract with a remedy attached.

What happens when wood packaging fails inspection?

APHIS inspectors may issue an Emergency Action Notification, or EAN, when a shipment contains noncompliant wood packaging or otherwise fails to comply. APHIS publishes a five-step roadmap for handling one: understand the violation, coordinate corrective actions, implement those corrective actions, conduct a traceback investigation, and mitigate risks for future shipments.

The immediate outcome can be harsher than a paperwork fix. Under 7 CFR 319.40-3(b)(3), an inspector at the port of first arrival may order the immediate reexport of regulated wood packaging that arrives without the required mark, in addition to or instead of other port procedures. Reexport means the cargo goes back, on your account.

Build the response before you need it. Keep photographs of every mark, the producer’s accreditation details, and the contact for your broker in one folder per shipment, because the traceback step in the APHIS roadmap is much faster when the paperwork already exists.

How do you source compliant wood packaging?

APHIS gives four instructions, and all four are cheap. Ask your wood packaging provider whether they are ISPM 15-compliant and accredited. Review the certification issued by the exporting country’s national plant protection organization. Share the ISPM 15 standard and the regulations with your exporter. And require your exporter to inspect the wood packaging for signs of pests on delivery or before use.

Then add the commercial lock: put ISPM 15 compliance in the contract, not just in an email. State that all wood packaging including dunnage must bear a valid mark, that photographs of every mark must be sent before loading, and that the supplier bears the cost of any detention or reexport caused by noncompliant wood.

That clause changes behavior upstream. Suppliers who know they will pay for a rejected container stop treating pallets as an afterthought, and the price of a compliant pallet is a rounding error next to a reexport.

Do wooden pet products need the same treatment?

Not automatically, and the distinction is worth understanding before you panic about a container of cat scratchers and trees. ISPM 15 governs wood packaging material: the pallet, crate or dunnage that carries the goods. A wooden pet product is cargo rather than packaging, and the two are assessed under different rules.

That does not mean raw wood in the product itself is ignored. Solid wood articles can raise plant pest questions of their own, and processed wood such as plywood or engineered board generally does not. The reliable move is to check the APHIS Agricultural Commodity Import Requirements database, known as ACIR, for the specific article, or to have your licensed customs broker confirm the requirement before the goods ship.

This article is a practical checklist, not legal advice. Where the classification of a product is uncertain, get a written answer from your broker or from APHIS before you commit to the order.

What should go into your purchase order and receiving checklist?

Write six lines into every purchase order that involves wood. All wood packaging including dunnage must meet ISPM 15. Every piece must carry a legible, permanent mark with the IPPC symbol, country code, producer number and treatment code. Photographs of the marks must be sent before container loading. The producer’s accreditation must be current. The supplier is liable for detention, treatment or reexport costs arising from noncompliant wood. And no mixed loads of marked and unmarked pallets.

On receiving, photograph the pallets and dunnage before unloading, and keep those images with the entry documents for the record retention period. If a mark is missing or unreadable at that point, stop and call your broker rather than unpacking, because an intact shipment is far easier to reexport cleanly than a half-unloaded one.
