Wood Packaging Materials and ISPM 15: Quarantine Practices for Wooden Pallets, Crates, and Dunnage
Interlink編集部What Are Wood Packaging Materials and ISPM15?
Wood packaging materials and ISPM15 refer to the practices of verifying treatment and marking based on international standards for wooden pallets, crates, frames, dunnage, skids, cable drums, and other wooden packaging materials used in international transport to prevent the cross-border movement of pests and diseases.
Wood packaging materials are not cargo themselves but materials used to hold, protect, secure, and transport cargo. However, if untreated or inadequately treated wood is used, it carries the risk of harboring and spreading pests and diseases. Therefore, in export and import operations, it is necessary to confirm that not only the cargo itself but also any wooden packaging materials comply with ISPM15 requirements.
In practice, even when the cargo itself is not plant-based—such as machinery, parts, food products, sundries, or exhibition goods—deficiencies in wooden pallets, crates, or dunnage can lead to local import holds, re-treatment, disposal, returns, delivery delays, and additional costs.
Scope Covered in This Article
This article organizes key practical points that freight forwarders, customs brokers, exporters, and importers should verify concerning wooden packaging materials and ISPM15. It focuses specifically on wooden packaging materials within the plant quarantine system, covering applicable materials, potentially exempt materials, the IPPC mark, checks at export and import, and responses to non-compliance.
Import inspections of plants themselves, export plant quarantine, plant quarantine certificates, and CITES are topics covered in separate articles. This article focuses on practical quarantine risks arising from packaging materials rather than the cargo itself.

Positioning of the System
Quarantine measures for wooden packaging materials are primarily managed based on the international standard ISPM15, established under the framework of the International Plant Protection Convention. ISPM15 defines treatment methods to reduce pest risks and specifies markings that indicate the packaging material has been treated.
In Japan, at the time of import, phytosanitary inspections under the Plant Protection Act may raise concerns regarding the treatment markings on wooden packaging materials or the presence of pests. For exports, if the destination country requires ISPM15-compliant quarantine, it is necessary to confirm treatment and markings according to the Export Wooden Packaging Material Disinfection Guidelines.
Wooden packaging materials should be assessed separately from the cargo’s product classification and import/export customs clearance. Even for non-plant cargo such as machinery or general merchandise, the use of wooden pallets, wooden boxes, or dunnage could pose phytosanitary issues.
Main Types of Wood Packaging Materials Subject to Inspection
Wood packaging materials include wooden items used for cargo retention, protection, securing, and transportation. In practice, this extends beyond pallets and wooden boxes to include small wood pieces used for securing cargo, reinforcements, and dunnage, all of which may be subject to inspection.
| Type of Wood Packaging Material | Typical Examples | Points to Confirm | Practical Notes |
|---|---|---|---|
| Wooden Pallets | Wooden pallets used for cargo handling and storage during import/export. | Confirm whether the material is treated, bears the IPPC mark, and whether the marking is legible. | With reused pallets, watch for missing or unclear markings. |
| Wooden Boxes and Crates | Wooden boxes or crates used for packaging machinery, equipment, precision instruments, and oversized cargo. | Check not only the exterior wooden parts but also internal reinforcements and securing materials. | Untreated wood may be mixed within parts of the wooden box. |
| Dunnage and Base Materials | Wood materials used inside containers or during loading to secure cargo. | Confirm whether treated, properly marked, and free of untreated wood mixture. | These materials are often overlooked separately from the cargo packaging itself. |
| Skids and Support Materials | Wooden bases or supports used to hold heavy or long cargo. | Confirm material type, treatment markings, securing methods, and import country requirements. | Particularly important to verify for oversized machinery shipments. |
| Cable Drums, Reels, and Spools | Wooden drums used for winding cables or wires. | Confirm treatment and markings on wooden parts and whether the item is reused. | It may be difficult to distinguish the packaging wood components from the product itself. |
| Blocking and Reinforcement Wood | Small wooden pieces such as wedges and blocking used to secure cargo. | Check that untreated wood is not used. | Even small amounts of untreated wood can cause non-compliance. |
Processed Wood Materials That May Be Exempt
ISPM15 does not apply uniformly to all wood products. Processed wood materials such as plywood, particle board, OSB, and veneer—which have reduced pest risk through manufacturing processes—may be exempt.
However, whether a material is exempt can vary depending on its composition, thickness, structure, usage, and the importing country’s regulations. If solid wood is used in parts of wooden boxes or pallets, the entire item may require inspection.
| Material | Reason for Possible Exemption | Points to Confirm | Notes |
|---|---|---|---|
| Plywood | The pest risk may be reduced through bonding, heating, and compression processes. | Confirm whether the entire structure is plywood and that no solid wood is mixed in. | Untreated wood may be used in the frame or reinforcement components. |
| Particle Board | Being a processed wood material, it may be exempt. | Check material certification, structure, and the part where it is used. | The importing country may require additional verification. |
| OSB | Often treated as processed wood made by bonding and compressing wood chips. | Confirm if the item is composed solely of OSB. | Be cautious of combinations with solid wood legs or reinforcements. |
| Veneer / Thin Wood Sheets | Considered low risk for pests due to processing. | Confirm material, thickness, structure, and importing country requirements. | Verification methods may differ depending on the country or region. |
| Paper Products / Corrugated Board | Treated as paper packaging, not wood packaging materials. | Check that wood components are not used alongside. | Wooden pallets are sometimes used together with corrugated packaging. |
Checks at Export
When using wooden packaging materials for cargo exported from Japan, first confirm whether the destination country requires quarantine measures based on ISPM15. Many countries and regions mandate the use of treated wooden packaging materials and specified markings.
For export wooden packaging materials, compliance with treatment by certified treatment operators or production and marking by registered producers is crucial. Improper treatment by unregistered operators or illegible markings can cause customs clearance delays, re-treatment, return shipments, or disposal in the destination country.
| Check Item | Details to Confirm | Counterpart to Confirm With | Actions if Issues Arise |
|---|---|---|---|
| Destination Country Requirements | Confirm whether the destination country requires ISPM15 compliance. | Exporter, Importer, Local Agent, Freight Forwarder | If requirements are unclear, defer the decision on using wooden packaging materials. |
| Treated Materials | Verify the wood has undergone approved treatments such as heat treatment or fumigation. | Packer, Certified Treatment Operator, Registered Producer | If untreated material is used, replace it with treated material. |
| IPPC Mark | Check that the country code, registration number, and treatment code are correctly displayed. | Packer, Warehouse, Exporter | If markings are deficient, consider re-marking or re-packaging. |
| Legibility of Markings | Confirm markings are not worn off, unclear, or improperly placed. | Packer, Warehouse, Freight Forwarder | Take photos and replace markings if necessary. |
| Mix of Untreated Material | Check that stop blocks, reinforcements, and dunnage do not include untreated wood. | Packer, On-site Staff, Warehouse | Remove untreated materials and replace them with treated ones. |
| Destination Country Additional Requirements | Confirm if additional requirements exist for marking methods, treatment methods, or certification documents. | Importer, Local Customs Broker, Destination Country Information | Verify if standard ISPM15 compliance alone is sufficient. |
Checks at Import
When wood packaging materials are used for cargo imported into Japan, the Plant Protection Station may inspect for the presence of ISPM15 treatment marks and signs of pest infestation based on the ISPM15 standard.
If wood packaging materials that do not meet the standards are found, the Plant Protection Station may require measures such as disinfection, disposal, or return shipment. Importers and customs brokers should verify both the cargo itself and the packaging materials’ composition and markings in advance.
| Check Item | Details to Confirm | Party to Confirm With | Actions if Issues Are Found |
|---|---|---|---|
| Presence of Wood Packaging Materials | Confirm whether pallets, wooden crates, dunnage, blocking, or similar materials are used. | Exporter, Overseas Freight Forwarder, Packaging Supplier | If used, verify treatment markings and material type. |
| ISPM15 Mark | Check for treatment markings and ensure required information is legible. | Exporter, Packaging Supplier, Customs Broker | Obtain photos and confirm any discrepancies before arrival. |
| Pest Infestation | Check for insect damage, boreholes, wood debris, or other pests. | Importer, Warehouse, Plant Protection Station | If suspected, follow instructions from the Plant Protection Station. |
| Bark, Soil, and Decay | Inspect for presence of bark, soil attachment, decay, moisture, or mold. | Exporter, Warehouse, Customs Broker | Document condition with photos or physical inspection. |
| Handling Non-compliance | Confirm disinfection, disposal, return shipment, and whether wood packaging can be separated. | Plant Protection Station, Customs Broker, Warehouse, Importer | Address impact on cargo, costs, and storage duration. |
| Impact on Customs Clearance and Release | Check whether cargo can be released before completion of phytosanitary inspection. | Customs Broker, Plant Protection Station, Warehouse | Do not proceed with regular delivery until inspection and treatment are completed. |
ISPM15 Treatments and Markings
ISPM15 requires treatments for wooden packaging materials to reduce risks of pests and diseases, as well as markings that indicate the materials have been treated. Common treatment methods include heat treatment, methyl bromide fumigation, dielectric heating, and sulfuryl fluoride treatment.
The available treatment methods, treatment conditions, and marking requirements vary depending on Japan’s regulations, the importing country’s requirements, and the operating practices of the registered treatment providers. Knowing the treatment code alone does not guarantee that the treatment is accepted for export to a specific country.
| Treatment Code | Treatment Method | Practical Meaning | Notes |
|---|---|---|---|
| HT | Heat Treatment | Wood is heated under specified conditions to reduce pest and disease risks. | Confirm treatment conditions and management by the registered provider. |
| MB | Methyl Bromide Fumigation | Fumigation using chemicals to reduce pest and disease risks. | Check environmental regulations and acceptance by the destination country. |
| DH | Dielectric Heating | Wood treatment by dielectric heating technology. | Verify actual usability and operational conditions. |
| SF | Sulfuryl Fluoride Treatment | One of the chemical treatment methods using sulfuryl fluoride. | Confirm acceptance by the destination country and domestic operational status. |
Items to Verify with the IPPC Mark
The IPPC mark is a crucial indicator that the wood packaging material has undergone treatment according to ISPM15 standards. In practice, it is necessary not only to check for the presence of the mark but also to ensure that the information is legible, all required details are present, and the mark is placed in an appropriate location.
| Verification Item | Meaning | Common Issues | Practical Response |
|---|---|---|---|
| IPPC Symbol | Indicates compliance with international phytosanitary standards. | Missing mark, illegible, or unclear imprint. | Confirm with the packer and replace with treated material if necessary. |
| Country Code | Shows the country where treatment or production was performed. | Country code unreadable or missing. | Take photos and verify against the importing country’s requirements. |
| Registration Number | Identifies the registered treatment or production operator. | Blurry number, unregistered mark, or outdated mark. | Confirm involvement of the registered operator. |
| Treatment Code | Indicates treatment method such as HT, MB, DH, SF, etc. | No treatment code or treatment method not accepted by the destination country. | Confirm if the treatment method is accepted by the importing country. |
| Mark Location | Placement should allow easy inspection. | Mark hidden after loading or visible from only one side. | Check mark placement before packing is completed. |
| Mark Condition | Check clarity of imprint, signs of tampering, or overwriting. | Worn, smudged, concealed by paint, or overlaid marks. | Consider repacking or replacement if the mark is unclear. |
Differences Between Export and Import
The inspection focus for wood packaging materials differs between export and import. At export, it is important to confirm whether the destination country requires ISPM15 compliance and if the treated materials are properly marked. At import, the concerns involve the markings in Japan, presence of pests or diseases, and measures taken if non-compliance occurs.
| Category | At Export | At Import | Practical Points of Contact |
|---|---|---|---|
| Inspection Focus | Confirm whether the wood packaging complies with the requirements of the destination country. | Confirm whether the wood packaging on cargo imported into Japan is non-compliant. | Exporter, importer, Plant Protection Station, local agent |
| Main Items Checked | Requirement for ISPM15, treated material, IPPC mark, and any specific requests from the destination country. | Presence of markings, attached pests or diseases, untreated materials, and whether inspections or measures have been performed. | Packing companies, customs brokers, freight forwarders |
| Consequences of Non-Compliance | Import suspension at destination, re-treatment, return shipment, disposal, and delivery delays become issues. | Import inspection, disinfection, disposal, return shipment, customs clearance hold become issues. | Warehouse, shipping company, airline, cargo owner |
| Timing of Inspection | Confirm at quotation, order acceptance, before packing, and before shipment. | Confirm before shipment, before arrival, before inspection, and before customs clearance. | Exporter, importer, freight forwarder |
| Main Cost Risks | Repacking costs, shipment delays, local storage fees, return shipping costs. | Disinfection fees, disposal costs, storage charges, demurrage, detention. | Exporter, importer, contracting parties |
Comparison with Other Systems
Wood packaging materials and ISPM15 are practical issues handled under the plant quarantine system, but their purpose differs from plant quarantine of the cargo itself, the Food Sanitation Act, CITES, and import/export customs clearance. It is important to clearly distinguish which system covers what verification.
| System/Procedure | Main Purpose | Main Target | Relation to Wood Packaging Materials | Practical Points |
|---|---|---|---|---|
| Wood Packaging Materials and ISPM15 | Reduce the risk of pest and disease transfer through wood packaging materials. | Wooden pallets, wooden crates, dunnage, etc. | Core focus of this article. | Verification is needed even if the main cargo is non-plant material. |
| Import Plant Quarantine | Prevent entry of pests and diseases via plants and plant-derived products. | Plants, agricultural products, timber, soil-contaminated items, etc. | Wood packaging materials are sometimes an issue at import. | Main cargo and packaging materials should be checked separately. |
| Export Plant Quarantine | Confirm compliance with the import country’s plant quarantine requirements. | Exported plants and plant-derived products. | Some importing countries require ISPM15 treatment of wood packaging materials. | Check the destination country’s requirements carefully. |
| Phytosanitary Certificate | Certify that plants or plant-derived goods meet quarantine conditions. | Plant and plant-derived cargo. | Wood packaging materials are often controlled separately by the IPPC mark. | Do not confuse the certificate with the IPPC mark. |
| Food Sanitation Act | Ensure the safety of food products. | Food, food additives, utensils, containers, packaging, etc. | If wooden pallets are used even for food cargo, ISPM15 verification may be required separately. | Separate notification of food cargo from packaging material verification. |
| CITES | Regulate international trade of rare wild fauna and flora. | Rare timber, orchids, cacti, etc. | Separate CITES verification may be required for wood products or rare timber. | Confirm scientific names, species, and origin. |
Common Misconceptions
In practice with wooden packaging materials, there are many misunderstandings such as skipping checks because the main cargo is not a plant, or assuming that having the IPPC mark on just part of the packaging is sufficient. Even if the main cargo is problem-free, deficiencies in packaging materials could cause customs clearance delays or returns.
| Common Misconception | Actual Consideration | Practical Notes |
|---|---|---|
| If the main cargo is not a plant, it’s irrelevant | Even with machinery or general merchandise, ISPM15 verification may be needed if wooden packaging materials are used. | Check the main cargo and packaging materials separately. |
| Only wooden pallets need to be checked | Wooden boxes, frames, dunnage, blocking pieces, and reinforcements can also pose issues. | Verify the entire packaging. |
| Any presence of the IPPC mark is sufficient | If the mark is unclear, missing, unreadable, or lacks required information, it could cause problems. | Confirm the content and legibility of the marking. |
| Plywood is always exempt from checks | Processed wood products may be exempt, but if solid wood is mixed in, verification is necessary. | Check the material type and structure. |
| Used pallets are fine if they have previous markings | For reused pallets, missing, unclear, damaged markings, or swapped wood pieces cause issues. | Physically inspect reused pallets before use. |
| A phytosanitary certificate covers wooden packaging materials too | Cargo phytosanitary certificates and ISPM15 markings on wood packaging are managed separately. | Avoid confusing certificates with IPPC marks. |
| The freight forwarder will handle all decisions | Freight forwarders can assist with verification, but documentation confirming packaging specifications and treated materials must come from the shipper or packer. | Obtain photos and specification sheets from the packer or exporter. |
| Non-compliance can be easily fixed locally | Reprocessing, disposal, or returns at destination cause significant time, cost, and schedule impacts. | Minimize deficiencies before shipment. |
Common Practical Issues
Problems related to wooden packaging materials can arise not only from incomplete markings on wooden pallets but also from dunnage, blocking, bracing, reused materials, mixing plywood and solid wood, and overlooking the importing country’s specific requirements. In the following cases, pre-shipment verification is especially important.
| Case | Potential Issue | Documents to Verify | Practical Precautions |
|---|---|---|---|
| Wooden pallets without IPPC marks | May be considered untreated material by the export destination or importing country. | Photos of pallets, packaging specifications, proof of treatment | Replace with treated pallets before shipment. |
| Unclear markings | Markings exist but country code, registration number, or treatment code may be unreadable. | Photos of IPPC marks, actual packaging, registered operator documents | Confirm that markings are legible in advance. |
| Untreated materials mixed in dunnage | Even if the pallet for the main cargo is compliant, the securing materials may be non-compliant. | Loading photos, packaging specifications, warehouse operation records | Include dunnage and blocking materials in the verification scope. |
| Solid wood used in part of wooden crates | Although described as plywood, reinforcement parts may be solid wood. | Material certificates, crate drawings, photos, confirmation from packer | Check the entire material composition of the wooden crate. |
| Use of reused pallets | Damage to treatment markings, material replacement, or unclear markings may cause issues. | Photos of actual pallets, pallet history, packer confirmation | Avoid using reused materials if condition or treatment status is unclear. |
| Overlooking importing country’s specific requirements | Standard ISPM15 markings alone may not suffice. | Export destination information, confirmation from local importer, customs broker verification | Confirm country-specific requirements through the importer. |
| Post-import detection of pests or diseases | Even with treatment markings, pests or abnormalities may be found. | Photos of the item, inspection results, Plant Protection Station instructions | Confirm options for disinfection, disposal, re-export, or separation. |
| Delivery delays of main cargo due to wooden packaging deficiencies | Even if the cargo itself is problem-free, release may be delayed until packaging issues are resolved. | Inspection reports, warehouse storage status, delivery schedules, cost statements | Clarify deadlines, storage fees, and cost responsibilities early. |
4-Column Decision Checklist
In the case of wooden packaging materials, the items to verify change depending on the stage: quoting, before packing, before loading, before arrival, during inspection, and when non-compliance occurs. It is important to check not only the customs documents for the cargo itself but also the actual packaging materials, photos, and specifications.
| Verification Stage | Contact Party | Items to Confirm | Actions if Issues Arise |
|---|---|---|---|
| Quotation Stage | Exporter, Importer, Freight Forwarder | Confirm whether wooden packaging materials will be used and if the destination country requires ISPM15 compliance. | Quote on the basis of treated materials rather than regular packaging. |
| Before Packing | Packing Contractor, Warehouse, Exporter | Confirm whether wood is treated, if the supplier is a registered operator, presence of IPPC mark, and whether untreated wood is mixed. | Replace any untreated wood with treated wood. |
| Before Loading | Freight Forwarder, Exporter, Packing Contractor | Check photos and readability of markings on wooden boxes, pallets, dunnage, and display labels. | If markings are inadequate, consider repacking or replacing the packaging. |
| Before Arrival | Importer, Customs Broker, Overseas Freight Forwarder | Confirm whether imported cargo uses wooden packaging and check for display photos. | If there are doubts, adjust inspection and in-gate planning accordingly. |
| During Import Inspection | Plant Protection Station, Warehouse, Customs Broker | Check markings, presence of pests, bark, soil, decay, and untreated wood. | Follow Plant Protection Station instructions and consider disinfection or disposal. |
| When Non-Compliance Occurs | Importer, Exporter, Freight Forwarder, Warehouse | Confirm responsibilities for disinfection, disposal, return shipment, separation, repacking, storage fees, and cost allocation. | Check if cargo and packaging materials can be handled separately. |
| Before Delivery | Importer, Delivery Company, Delivery Location | Confirm completion of quarantine measures, permission for gate-out, delivery date, and impact on delivery schedule. | Do not finalize delivery plans before measures are completed. |
Scope of Involvement for Freight Forwarders and Customs Brokers
Freight forwarders and customs brokers are not ultimately responsible for guaranteeing that wooden packaging materials comply with ISPM15. However, because they handle transport arrangements, packaging checks, customs clearance, inspection locations, delivery, and storage fees, they play a critical role in early detection of any confirmation oversights.
Especially for large machinery, equipment cargo, heavy items, wooden box packaging, exhibition goods, and re-export cargo, delayed confirmation of packaging materials may lead to customs clearance delays and delivery schedule setbacks.
| Category | Areas Where Support Is Easier | Actions to Avoid Definitive Judgments | Practical Response |
|---|---|---|---|
| Confirmation of Packaging Materials | Confirm with the shipper whether wooden pallets, wooden boxes, or dunnage are used. | Assuming no check is needed because the cargo itself is non-plant-based. | Obtain packaging specifications and photographs. |
| Support for Confirming ISPM15 Requirements | Verify the possibility that the destination country requires ISPM15 compliance. | Make an independent final decision on the destination country’s conditions. | Refer inquiries back to exporters, importers, and local customs brokers. |
| Verification of IPPC Mark | Support confirmation of presence, legibility, and photographing of the mark. | Guarantee full compliance based only on the photographs. | Request re-confirmation if the images are unclear. |
| Packaging Schedule Management | Coordinate preparation of treated materials, packaging dates, in-gate days, and loading dates. | Assure that the schedule will always match regular packaging days. | Plan with allowance for the lead time needed to arrange treated materials. |
| Procedures for Non-Compliance | Support arrangements for disinfection, disposal, return shipment, re-packaging, storage, and delivery changes. | Unilaterally decide on cost burden or legal responsibility. | Confirm the terms of sales contracts, transport contracts, and insurance conditions with involved parties. |
| Sharing Delivery Schedule Impact | Share the possibility of delivery delays due to inspections or measures. | Guarantee delivery dates before quarantine actions are completed. | Communicate status updates to consignee, importer, and delivery companies. |
Example 1: Exporting Machinery Cargo in Wooden Boxes
When exporting machinery cargo from Japan, the cargo itself is not plant material. However, if wooden boxes, wooden frames, skids, or blocking materials are used, and the destination country requires ISPM15 compliance, the treatment and marking of the wooden packaging materials become important.
The exporter should instruct the packer to use treated materials before packing and verify the placement and legibility of the IPPC mark. The freight forwarder needs to be aware of the wooden box packaging at the quotation and shipment arrangement stage and should prompt the shipper to confirm the destination country's requirements.
If the marking is unclear and the goods are shipped as is, even if the cargo itself has no issues locally, problems with the packaging materials could result in import holds, reprocessing, returns, or delivery delays.
Example 2: When No Markings Are Present on Imported Wooden Pallets
For cargo imported into Japan, if the wooden pallet lacks treatment markings, it may be subject to phytosanitary inspection. If pests are detected or the pallet is determined to be untreated, measures such as fumigation, disposal, or return shipment may be required.
Importers and customs brokers should obtain packaging photos before arrival to confirm whether wooden pallets are used and to check their marking status. If markings are absent or unclear, all parties should be informed to prepare for possible post-arrival inspection, storage, and cost responsibilities.
Even if the customs clearance documents for the cargo itself are in order, the release or delivery of the cargo may be delayed until the packaging materials’ compliance measures are completed.
Example 3: When Only the Dunnage Is Untreated Wood
Even if wooden pallets and crates are treated, there may be non-compliance if the dunnage or blocking wood used inside the container to secure the cargo is untreated.
Such issues can arise from materials added at the warehouse or site, rather than from the packing company. Exporters and freight forwarders should verify that not only the materials supplied by the packing company but also any additional wood added during stuffing are treated.
Even small dunnage components could cause quarantine issues as wooden packaging materials in the importing country. Maintaining photographic records and confirming the stowage condition are practical measures in actual logistics practice.
Example 4: When a Plywood Box Is Assumed but Contains Solid Wood
Wooden boxes made from processed wood materials such as plywood or OSB may be exempt from ISPM15 regulations. However, if solid wood is used for parts like the box’s feet, frame, reinforcements, or blocking, those components may require inspection.
Even if the exporter assumes "It’s a plywood box, so there’s no issue," solid wood reinforcements can still be present. In such cases, it is necessary to review packing diagrams, material certificates, and actual photos to determine whether the structure can be considered exempt.
Freight forwarders and customs brokers should not make a definitive material judgment themselves. Instead, they should collect documentation from the packer or cargo owner and, if any doubts arise, refer the matter back to the plant quarantine office or the local importer for confirmation.
Relationship with Cargo Insurance and Logistics Costs
When deficiencies in wooden packaging materials cause import holds, reprocessing, disposal, returns, repacking, storage, or delivery changes, charges such as storage fees, demurrage, detention, handling costs, disposal costs, return shipping costs, repacking fees, and losses due to delivery delays become an issue.
These expenses are not necessarily covered by marine cargo insurance. Typically, cargo insurance focuses on covering accidental physical damage during transportation. Costs related to non-compliant packaging materials, quarantine measures, customs clearance delays, or regulatory violations may fall outside the scope of coverage.
Therefore, for exports and imports using wooden packaging materials, it is important to confirm ISPM15 requirements, IPPC marking, treated versus untreated materials, mixed condition issues, and cost responsibilities for non-compliance before shipment.
Summary
ISPM15 and wood packaging materials cover the practical inspections related to wood pallets, boxes, frames, and dunnage used in international transport to prevent the cross-border spread of pests and diseases.
Even if the cargo itself is not plant-based, deficiencies in wood packaging materials alone may lead to holds, reprocessing, disposal, returns, delayed delivery, or additional charges in the export or import country. Particular attention should be given to the presence of the IPPC mark, legibility of markings, mixed use of untreated materials, and the verification of reused pallets and dunnage.
Shippers, consignees, freight forwarders, and customs brokers should treat wood packaging materials as a separate inspection item from the cargo itself and establish clear procedures for ISPM15 compliance and possible corrective actions before packing, before shipment, and prior to arrival.
