Which parts of the consignment need the wood-packaging check?
Start with the actual load, rather than the pallet description on a quote. A shipment of circumcision devices, laser fibers or sterile dressings may use a marked pallet and still acquire unmarked wood when someone adds bracing during container loading. ISPM 15 covers raw-wood packaging, including dunnage, even where the cargo itself would not normally receive a plant-health inspection. 1
The standard exempts packaging made entirely from wood no thicker than 6 mm and packaging made wholly from processed wood such as plywood, particle board, OSB or veneer produced using glue, heat or pressure. APHIS also lists plastic pallets and metal frames as alternatives outside its wood-packaging requirements. These are scope exemptions, rather than certificates of cleanliness, mechanical suitability or device-package performance. 12
| Shipment layer | ISPM 15 question | Evidence for the acceptance file |
|---|---|---|
| Sterile pouch or blister; paperboard carton | Not regulated raw-wood packaging. Review the device packaging file separately. | Product and packaging identity, applicable validation and release records. 9 |
| Solid-wood pallet, skid, crate or collar | Raw-wood components outside an exemption require the applicable treatment and mark. | Material construction, visible marks and condition photographs. 1 |
| Plywood or OSB deck on solid-wood runners | The mixed unit is not wholly processed wood. Its regulated wood still needs compliance. | Component list; authorised provider confirmation; mark on the composite unit. 1 |
| Wholly processed-wood pallet | Confirm the complete construction, including feet, blocks and reinforcement. | Material specification identifying all components; do not rely only on the word plywood. 1 |
| Plastic or metal pallet | Outside the raw-wood scope; inspect any added timber separately. | Load-support specification and receiving-site requirements. 2 |
| Loose blocking, spacers or dunnage | Regulated pieces need treatment and a complete legible mark after cutting. | Inspection of the pieces actually loaded, including additions by the forwarder. 1 |

Ask for a packaging component list during the RFQ and compare it with the load at dispatch. For a supposedly all-plywood design, the useful follow-up is “What are the feet and runners made from?” For loose dunnage, check the cut pieces: a mark elsewhere on the original long board does not identify an unmarked offcut as compliant. Annex 2 specifically addresses retaining a complete mark on dunnage used in the shipment. 1
What must the IPPC mark show?
Annex 2 identifies the required symbol and codes and allows variation in size, font and layout. The country code must be separated from the producer or treatment-provider code by a hyphen. The provider code identifies an entity authorised within the relevant national plant protection organisation’s system; it is not a universal kiln-batch number. 1
| Check | Source-backed requirement | Buyer action |
|---|---|---|
| Symbol and frame | IPPC symbol to the left of the codes, within a rectangular or square border with a vertical dividing line. Small stencil gaps are permitted. | Compare with Annex 2 examples; do not reject legitimate stencil gaps as a missing border. 1 |
| Country and provider | ISO two-letter country code, a hyphen, and the nationally assigned producer/treatment-provider code. | Record the full code and compare it with the declared authorised provider. 1 |
| Treatment | HT, DH, MB or SF under the standard; treatment code follows the combined country/provider codes on a separate line, or after a hyphen on the same line. | Check the destination programme and any separately agreed purchasing restriction. 1 |
| Durability and visibility | Legible, durable, non-transferable and visible when the packaging is in use; not hand drawn. | An invoice or loose label does not replace the required mark on the unit. 1 |
| Position | Preferably on at least two opposite sides under Annex 2 and the US rule. | Specify two accessible sides as a buyer requirement if needed; do not describe it as a universal legal minimum. 15 |

Record photographs before stretch wrapping or loading makes the mark difficult to inspect. Do not make a replacement stamp or add missing characters yourself. APHIS directs buyers to accredited providers and expressly says an unregistered business cannot make its own official mark. If identity or authenticity is uncertain, ask the provider or competent programme to resolve it before dispatch. 23
A composite unit may legitimately display its mark on a processed-wood component, even though that component itself does not require treatment. This keeps the mark visible while the regulated wood elsewhere in the unit is covered. Conversely, a loose piece of dunnage needs its own complete mark. A single photograph of a pallet stringer is therefore insufficient evidence for all wood used in a container. 1
What do the treatment codes establish?
Treatment codes identify phytosanitary measures. They do not grade a pallet’s load capacity, certify a cleanroom surface, or establish compatibility with a particular sterile-device packaging system. Use the table to interpret a provider’s claim; treatment execution and validation belong to the authorised treatment provider. 19
| Code | What the standard specifies | What the buyer still checks |
|---|---|---|
| HT | Conventional heat treatment: at least 56°C for at least 30 continuous minutes throughout the wood profile, including the core. | Authorised treatment and marking; moisture, cleanliness and structural requirements remain separate. 1 |
| DH | Dielectric heating: at least 60°C for one continuous minute throughout the wood profile, including the surface. | The provider’s approved programme and destination acceptance; confirm both with the authorised provider. 1 |
| MB | Methyl bromide fumigation under Annex 1 schedules and limitations. | Rules for import of treated packaging are distinct from permission to conduct fumigation locally. 1 |
| SF | Sulfuryl fluoride fumigation under Annex 1 schedules and limitations. | Verify destination implementation and the authorised provider; listing in ISPM 15 is not a universal use licence. 1 |
Source: Treatment meanings and parameters: ISPM 15 Annex 1, source 1. Destination verification: source 3.
An HT mark is not a moisture certificate. Annex 1 sets treatment parameters and discusses moisture as a factor affecting treatment, but does not impose a universal 19% finished-wood moisture limit. If your packaging specification needs a moisture criterion, define its basis, measurement method and acceptance responsibility separately. Do not accept a damp or damaged load solely because it carries an HT mark. 1
For EU imports, Article 43 of Regulation (EU) 2016/2031 refers to the approved treatments and exemptions in ISPM 15, which includes MB. That import provision does not create a blanket prohibition on an otherwise compliant MB-marked pallet. Permission to apply a fumigant within the EU is a separate legal question: Article 96 also preserves applicable chemical legislation. A buyer may specify HT as a purchasing condition, but should label that condition clearly rather than call every MB mark an EU import violation. 18
When do bark, repairs and reuse change the decision?
Treatment does not give ongoing protection against later contamination. Inspect the wood that will actually ship, including replacement boards, pest signs and residual bark. ISPM 15 permits visually separate bark pieces less than 3 cm wide regardless of length; for pieces greater than 3 cm wide, the individual surface area must be less than 50 cm². Record measurements and refer borderline findings to the provider instead of using an approximate object size as the acceptance rule. 1
The order of debarking also depends on treatment. For MB and SF fumigation, bark is removed before treatment; with heat treatment it may be removed before or after. A receiving checklist should assess the finished wood against the requirement without inventing a universal process sequence for every provider. 1
| Unit history | ISPM 15 baseline | Acceptance follow-up |
|---|---|---|
| Reuse without alteration | A treated and marked unit that has not been repaired, remanufactured or otherwise altered does not need routine retreatment or remarking during its service life. | Verify readable marks, current condition and absence of pest signs; age alone is not an expiry date. 1 |
| Repair: up to approximately one-third of components replaced | Replacement wood must be treated and individually marked, or be exempt processed wood; national programmes may require whole-unit retreatment and remarking. | Identify the repair provider and applicable national programme. Do not assume every warehouse repair is authorised. 1 |
| Remanufacture: more than approximately one-third replaced | Previous marks must be permanently obliterated; the unit must be retreated and marked anew. | Obtain confirmation of the completed authorised process before release for international use. 1 |
| Several marks or uncertain history | Multiple marks alone do not constitute noncompliance under the standard. Uncertain treatment history warrants investigation. | Do not automatically condemn a legitimately repaired unit, or accept unexplained replacement lumber. 1 |
Source: ISPM 15 sections 4.3 and 4.6, source 1. US programme implementation, source 3.
National implementation matters. APHIS’s US export guidance requires repaired or remanufactured packaging to be retreated, with the old mark obliterated and a new mark applied. In the EU, Articles 97–98 address authorised operators and repair conditions. The standard’s approximate one-third distinction is therefore a trigger to investigate the correct programme, rather than permission for an exporter to replace boards and certify the result unaided. 38
What happens when the wood fails at the border?
For the United States, 7 CFR 319.40-3(b)(3) allows an inspector at first arrival to order immediate reexport of regulated wood packaging lacking the required mark. APHIS’s current Emergency Action Notification (EAN) roadmap also describes safeguarding, supervised destruction and reexport as options to coordinate with CBP and APHIS according to the finding. A buyer should not treat either a local fumigation booking or a switch to plastic pallets as automatic permission to release the goods. 25
The 2025 shredder-hammermilling announcement is a disposal option, not approval to use the original pallet. CBP’s bulletin was sent on August 8, 2025 and reports APHIS’s July 25 announcement. It requires an APHIS-approved facility within the port location and a compliance agreement covering the disposal equipment. Confirm availability and official authorisation for the particular shipment rather than assuming every port offers this option. 6
| Decision | United States | European Union |
|---|---|---|
| Applicable entry rule | Treatment and marking requirements in 7 CFR 319.40-3; APHIS also requires pest-free, debarked WPM. 2 5 | Article 43 links entry of regulated WPM to ISPM 15 treatment and marking; Commission guidance also specifies debarking. 48 |
| Who determines action? | CBP/APHIS contacts on the EAN; their instructions govern safeguarding and disposition. 2 | The competent member-state plant-health authority and customs under the relevant control procedure. 10 |
| Possible disposition | Immediate reexport of unmarked regulated WPM may be ordered; supervised destruction is among APHIS’s corrective options. 2 5 | PIORiN describes refusal, redispatch, treatment/cleaning or destruction among possible official decisions, according to findings. 10 |
| Can the cargo be separated? | Ask whether separation is authorised, where it may occur and under what safeguards. There is no automatic entitlement. 2 | Obtain the competent authority’s instructions before separating or moving goods. Do not import a US procedure into an EU case. 10 |
| What closes the incident? | Records of the authorised disposition, agency follow-up and the separate device-lot decision. 2 | Records of the official decision and its completion, plus the separate device-lot decision. 10 |
Source: US: sources 2, 5–6. EU: sources 4, 8 and 10. The table does not predict any individual enforcement outcome.
Neither the pallet mark nor the invoice tells you how much a hold will cost. CBP’s published penalty guidance identifies the responsible party as potentially the importer, carrier or bonded custodian, who must follow EAN instructions and bear disposition costs. It also describes possible penalties for documented violations. This does not support saying the importer always bears every loss, or that one purchase-order clause automatically transfers government-facing duties to a supplier. 7
Keep a shipment-specific cost record: authority instructions, approved handling quotes, storage terms, replacement transport packaging, disposition documents and revised delivery dates. For tenders, compare the revised date with the actual contract’s remaining-shelf-life requirement. Our remaining-shelf-life tender guide explains that calculation; no universal percentage or typical detention duration is assumed here.
A wood-packaging incident is also distinct from FDA’s review of device admissibility. If both processes affect a US consignment, track each notice and its resolution separately. Our FDA device detention and reconditioning guide covers that device-side workflow. Closing one file should not be used as evidence that another agency has released the shipment.
How does this fit with sterile-barrier validation?
FDA’s ISO 11607-1 recognition record describes packaging systems intended to maintain the sterility of terminally sterilized devices until use. ISPM 15 instead addresses quarantine-pest risks associated with raw wood. The practical conclusion is to keep separate evidence for those questions while coordinating the shipment’s final release. This is an interpretation of the two scopes, not a claim that transport design stops at a carton wall. 19
Changes in pallet design, stack geometry, wrapping or load support may need assessment against the device manufacturer’s established transport-packaging configuration. Conversely, a device sterilization record does not substitute for the wood’s required treatment and mark: EO and radiation are not the treatments listed in ISPM 15 Annex 1. Review the device file through the sterile-barrier and shelf-life validation guide, alongside the wood-packaging acceptance file. 19
After an officially authorised separation or restacking operation, document what changed and ask the responsible device-quality team to assess carton condition, labels, traceability and whether the established packaging configuration remains applicable. A pallet violation alone is not proof that the sterile barrier failed; equally, an intact-looking carton is not enough to establish suitability after an uncontrolled handling event. Record the assessment rather than issuing an automatic release or rejection.
What should the dispatch and receiving record contain?
The following is a proposed operational checklist, built from the source-backed requirements above. APHIS recommends accredited sourcing, exporter inspection for pest signs and compliance terms in contracts. The additional record fields connect those checks to a specific device shipment; they are buyer controls, not a claim that ISPM 15 mandates this exact form. 2
| Check | Record | If unresolved |
|---|---|---|
| Route and material scope | Destination, transit countries, pallet/crate construction and every loose timber addition. | Ask the broker/provider to confirm applicability before dispatch. 2 |
| Provider identity | Supplier, authorised producer/treatment-provider code, verification source and date. | Resolve mismatched or uncertain codes with the competent programme. 2 |
| Mark inspection | Full code and treatment, photographs, visibility after final loading. | Hold dispatch pending authorised correction; do not draw a new stamp. 1 |
| Bark and pest signs | Measured bark findings, exit holes, frass, feeding damage or insects; photographs. | Refer findings to the provider or competent authority; a mark does not override pest evidence. 2 |
| Repair history | Replacement parts, responsible repairer and any retreatment/remarking record. | Do not infer compliance from one surviving old mark. 1 |
| Device-packaging condition | Carton damage, dampness, load support and departures from the agreed configuration. | Obtain device-quality assessment separately from the phytosanitary decision. 9 |
| Release and incident responsibility | Named dispatch reviewer; receiving reviewer; broker contact; official notice and disposition if applicable. | Keep the shipment decision pending until the relevant owners resolve their findings. 2 |
Source: Proposed buyer record informed by sources 1–3; it is not an official regulatory form.
Use this record before loading and reconcile it on receipt. If a forwarder changes pallets or adds blocking, request updated photographs and details before departure. At receiving, compare the delivered unit with the recorded configuration. A certificate sent by the factory is less useful if the transport platform changed at a consolidation warehouse and nobody recorded the replacement.
How should buyers specify pallets and supplier responsibilities?
Choose a material using the actual load, route and receiving-site requirements. Wholly processed wood or plastic can remove the raw-wood treatment-and-marking question, but neither establishes cleanroom suitability, universal durability or a freight saving. Compare current quotes at the same dimensions, load rating, support conditions, tare mass and return/disposal arrangements. No comparable dated price corpus is available for a defensible cost ranking here. 12
| Field | What to request | Decision it supports |
|---|---|---|
| Construction and load support | All materials, dimensions, dynamic/static/racking ratings as applicable, load configuration and handling interface. | Whether the design fits the shipment and receiving warehouse. 1 |
| Plant-health compliance | Applicable route requirements; authorised provider; permitted treatment; mark format and visibility; control of dunnage. | Whether the regulated wood has the required evidence before loading. 2 |
| Buyer-specific conditions | Any HT-only preference, moisture/cleanliness criterion, inspection method and acceptance owner. | Which requirements are contractual additions rather than universal ISPM rules. 1 |
| Changes and repairs | Approval process for substitutions, replacement components and changed palletisation; national repair programme compliance. | Whether the approved design and mark history survive changes. 3 |
| Documents and incident support | Material list, provider verification, shipment photographs, traceable treatment records when agreed, response contacts. | Who can explain the delivered unit and support an authority enquiry. 2 |
| Commercial allocation | Responsibility for replacement, authorised handling/disposition costs, notification, evidence preservation and recovery terms. | A negotiated allocation assessed under the contract and applicable law. 7 |

ISPM 15 explains that the official mark makes a separate phytosanitary certificate unnecessary for covered packaging; APHIS likewise does not issue such a certificate for WPM used to transport commodities. A treatment record may still help qualify a supplier or investigate an incident. Label those additional documents as agreed supporting evidence; do not accept them in place of a required physical mark. 13
Suggested purchasing brief for adaptation: Identify the destination and transit route; require the applicable treatment, debarking and authorised marking for all regulated wood, including subcontracted dunnage; agree any stricter buyer conditions; preserve provider and shipment traceability; prohibit unapproved substitutions; and assign notification, corrective-action support and cost-recovery responsibilities. Have the parties assess the wording against their contract and applicable law. This brief is not a guarantee of indemnity, penalty recovery or border release.

Frequently asked questions
Does a plywood deck exempt the pallet?
Only a wholly qualifying processed-wood construction is exempt on that basis. Inspect the runners, blocks and any loose timber. A mixed unit may legitimately be marked on its processed-wood part, but its regulated wood must comply. 1
Must the stamp appear on two opposite sides?
The standard and US rule say preferably. Visibility, legibility and permanence remain required. Buyers can specify two accessible sides as a separate acceptance condition. 15
Does heat treatment expire?
Not simply with time on an unaltered treated and marked unit. Reuse still requires condition checks; repair or remanufacture changes the assessment and the national programme must be followed. 13
Does a compliant pallet prove that the devices stayed sterile?
No. The mark concerns wood treatment. The device-quality decision relies on the relevant packaging and release evidence. Equally, a sterile-device lot cannot establish that the raw-wood platform complies with plant-health rules. 19
Can we solve an EAN by replacing the pallet?
Request the responsible authority’s instructions before separation, movement or disposal. APHIS describes several corrective paths; none gives an importer automatic permission to restack and release a held consignment. 26
Is an MB mark itself a reason to reject an EU-bound shipment?
Not under a blanket rule derived from ISPM 15 or Article 43. Verify the relevant import requirements and distinguish them from local fumigant-use rules and an explicitly agreed HT-only purchasing condition. 18
