Meet international export packaging standards for sheet metal products. Learn about ISPM 15, dangerous goods regulations, marking requirements, and compliance documentation.
Introduction
Export packaging must comply with international standards and regulations to ensure smooth customs clearance and safe delivery. Non-compliant packaging can result in delays, fines, or rejection at the destination. At Fulei Metal, our export packaging meets all applicable international standards for our global shipments.
ISPM 15 (Wood Packaging)
What is ISPM 15?
The International Standards for Phytosanitary Measures No. 15 (ISPM 15) requires wood packaging materials to be treated to prevent the spread of pests and diseases. This standard applies to all wood packaging used in international trade, including pallets, crates, dunnage, and spacers.
Treatment Methods
Heat treatment (HT): wood heated to 56°C core temperature for at least 30 minutes. Most common treatment method. Methyl bromide (MB) fumigation: chemical fumigation. Being phased out due to environmental concerns. Some countries have banned MB.
IPPC Marking
Treated wood packaging must be marked with the IPPC (International Plant Protection Convention) mark. The mark includes: IPPC symbol, two-letter country code, unique facility identifier, treatment code (HT or MB). Mark must be visible on at least two sides of the packaging.
Compliance
Use only ISPM 15-compliant wood packaging for export. Purchase pre-treated packaging from certified suppliers. Maintain documentation of treatment. Do not use untreated wood for blocking, bracing, or dunnage. Non-compliant wood packaging will be rejected at destination port.
Packaging for Different Transport Modes
Ocean Freight
Most common for sheet metal export. Long transit time (2-6 weeks). High humidity environment. Rough handling at ports. Container loading required. Packaging must withstand: vibration, compression from stacking, moisture, temperature changes, multiple handling events.
Air Freight
Fast transit (1-5 days). Weight-sensitive pricing. Lower vibration and impact risk. Packaging can be lighter than ocean freight. Consider dimensional weight for pricing. Use lightweight materials.
Truck (Cross-Border)
Moderate transit time. Vibration from road transport. Border inspection. For shipments to neighboring countries. Follow ISPM 15 for wood packaging.
Rail
Growing mode for Asia-Europe trade. Long transit time. Vibration and temperature variations. Double-stack containers. Packaging must withstand extended transit.
Marking and Labeling
Shipping Marks
Standard shipping marks: consignee name and address, port of destination, package number (1 of N), gross weight, net weight, dimensions, country of origin. Marks should be: permanent (stenciled or printed), weather-resistant, on at least two sides.
Handling Instructions
Pictorial handling marks: fragile, this way up, keep dry, stack limit, sling here. ISO 780 symbols are internationally recognized. Marks should be on multiple sides for visibility from any angle.
Regulatory Labels
Country of origin label. Handling hazard labels if applicable. Wood packaging IPPC mark. Dangerous goods labels if applicable. Any destination-specific labels.
Barcode Labels
Product identification barcode. Quantity barcode. For automated tracking by carrier and receiver. Place on multiple sides for scanning accessibility.
Dangerous Goods (If Applicable)
When Sheet Metal Products Are Dangerous Goods
Some sheet metal products may be classified as dangerous goods if they contain: batteries, pressurized gas, flammable materials, magnetized materials. Most plain sheet metal products are not dangerous goods.
IATA (Air), IMDG (Sea), ADR (Road)
If products are dangerous goods: follow IATA Dangerous Goods Regulations for air freight. Follow IMDG Code for sea freight. Follow ADR for road transport in Europe. Packaging must meet UN specifications. Documentation required: Dangerous Goods Declaration.
Packaging Documentation
Packing List
Detailed list of contents. Include: product description, part number, quantity, weight, dimensions, package number. Packing list inside package and outside package. Multiple copies for customs and carrier.
Certificate of Origin
Documents the country of manufacture. May be required for preferential tariff treatment. Chamber of Commerce certification may be required. Specific format may be required by destination country.
Wood Packaging Declaration
Statement that wood packaging complies with ISPM 15. May be requested by customs or buyer. Include IPPC mark information. Keep treatment certificates on file.
Material Safety Data Sheet (MSDS)
May be required for products with surface treatments. Provides safety information about materials. Required for dangerous goods. May be requested by carrier or customs.
Destination-Specific Requirements
European Union
CE marking if applicable. REACH compliance documentation. RoHS compliance if applicable. Wood packaging ISPM 15 compliant. REACH/RoHS declarations for surface treatments.
United States
Wood packaging ISPM 15 compliant. FDA requirements if food-contact. FCC requirements if electronic. State-specific requirements (e.g., California Proposition 65).
Japan
Wood packaging ISPM 15 compliant. JIS standards may apply. Japanese labeling may be required. Import declaration requirements.
Korea
Wood packaging ISPM 15 compliant. KC certification if applicable. Korean labeling may be required. Import declaration requirements.
Packaging Quality Control
Pre-Shipment Inspection
Verify: correct packaging materials used, correct marking and labeling, correct product and quantity, correct weight, ISPM 15 compliance for wood, moisture protection in place, documentation complete.
Documentation Review
Verify all required documents are included: packing list, commercial invoice, certificate of origin, wood packaging declaration, compliance certificates. Verify document accuracy and consistency.
Photography
Photograph packaged products before shipping. Photograph loading into container. Photograph sealed container. Maintain photos for claims protection.
Common Export Packaging Problems
Inadequate Protection
Product damaged during transit. Cause: insufficient cushioning, poor blocking, inadequate moisture protection. Prevention: test packaging, follow specification, use adequate materials.
Non-Compliant Wood Packaging
Shipment rejected at destination. Cause: untreated wood, missing IPPC mark, expired treatment. Prevention: use certified suppliers, verify marks, maintain documentation.
Missing or Incorrect Documentation
Customs delays or fines. Cause: incomplete or incorrect documents. Prevention: documentation checklist, review before shipping, maintain templates.
Poor Labeling
Mishandling or misrouting. Cause: missing or illegible labels. Prevention: standard labeling procedure, weather-resistant marking, quality check before shipping.

Export Requirements That Stop Shipments, and What Each One Needs
Most export packaging problems are not about protection. They are about documentation and material compliance, and they stop a shipment at a border rather than damaging it.
| Requirement | Standard or rule | What it means practically | Consequence if missed |
|---|---|---|---|
| Wood packaging material | ISPM 15 | Solid wood used in pallets, crates and dunnage must be heat treated or fumigated and carry the official mark | The shipment can be refused entry or the wood destroyed, regardless of the product condition |
| Packaging performance testing | ISTA series or ASTM D4169 | A test programme that simulates the distribution environment, run on the actual packed unit | No evidence that the pack survives transit, and no basis for a claim |
| Marking and labelling | Customer and carrier requirements, and the destination country | Identification, quantity, weight, origin, and any required handling symbols | Delays at customs, or mishandling at the destination |
| Weight and dimension limits | Carrier and road regulations in the origin and destination countries | Pack dimensions and mass within the limits for the mode of transport | Re-packing at the port, at cost |
| Documentation | Commercial invoice, packing list and any certificate of origin | Documents that match the physical shipment exactly | Customs clearance delay even when the goods are correct |
| Restricted and declared materials | Destination country rules on certain substances and materials | Confirming that packaging materials comply, not only the product | A compliance issue raised against an otherwise compliant product |
ISPM 15 is the one to check first, because it is a hard requirement applied at the border and because the mark has to be on the wood itself. Using compliant, marked pallets and crates is cheap; discovering at the port that a subcontractor supplied untreated dunnage is not.
Frequently Asked Questions
Does ISPM 15 apply to plywood and engineered wood?
Processed wood products such as plywood, oriented strand board and particle board are generally outside its scope because of how they are manufactured, while solid wood pallets, crates and dunnage are within it. Confirm with the supplier and check for the mark on solid wood.
Should packaging be performance tested for every product?
For a new product or a new distribution route, yes. Once a pack design has a proven record on the same route, testing can be reduced to a periodic check and to any change in packaging or product.
Who is responsible for the documentation?
Contractually it varies, and that ambiguity causes delays. Establishing who produces the packing list and who verifies it against the physical shipment is worth doing before the first order.
