Packaging Requirements for Export Products
Why Export Packaging Requirements Matter
Export packaging serves multiple critical functions beyond just containing your products:
- Product Protection: Withstanding international transit conditions including multiple handling points, varying climates, and long distances
- Regulatory Compliance: Meeting destination country requirements for materials, marking, and documentation
- Cost Efficiency: Optimizing dimensions and weight to reduce shipping costs
- Brand Presentation: Creating positive first impressions with retail-ready packaging
- Supply Chain Efficiency: Enabling smooth handling, storage, and tracking throughout logistics
⚠️ The Cost of Poor Packaging
According to industry data, 11-15% of goods experience some damage during international shipping. Proper packaging can reduce this to under 2%. Damaged goods mean refunds, replacements, customer dissatisfaction, and wasted shipping costs – often totaling 5-10x the cost of proper packaging.

Frequently Asked Questions
How thick should export cartons be?
Standard export cartons typically use 5-layer corrugated (B or C flute) with minimum 200 lbs/in² bursting strength. Heavy items or long shipping distances may require double-wall construction (7-layer) with 275+ lbs/in² strength.
Do I need ISPM 15 for plywood packaging?
No, plywood and other processed wood products (OSB, particle board, MDF) are generally exempt from ISPM 15 as they’ve been processed in a way that eliminates pest risks. However, always verify with your destination country’s regulations.
What’s the maximum weight for a shipping carton?
While there’s no universal legal limit, best practice is 25-30 kg (55-66 lbs) maximum for manual handling safety. Heavier cartons should have “HEAVY” or “TEAM LIFT” warnings and may require two-person handling or mechanical equipment.
Can I use printed retail packaging as the shipping carton?
Yes, if the retail packaging is strong enough for shipping (ISTA testing recommended) and includes all required shipping marks. This is common for e-commerce and called “Ships In Own Container” (SIOC) or “Retail Ready Packaging” (RRP).
How do I calculate dimensional weight?
Dimensional weight = (Length x Width x Height) / Dimensional Factor. Common factors: 5000 for sea freight (cm), 6000 for international air (cm), 139 for domestic US (inches). Carriers charge based on the greater of actual weight or dimensional weight.
Conclusion
Proper export packaging is a critical investment that protects your products, ensures compliance, and optimizes logistics costs. Key takeaways:
- Three-layer approach: Primary (product), secondary (grouping), tertiary (shipping)
- Compliance first: ISPM 15, destination regulations, safety standards
- Test before production: Drop tests and compression tests prevent costly failures
- Clear communication: Detailed packaging specifications to suppliers
- Proper documentation: Complete packing lists and certificates
- Continuous improvement: Track damage rates and optimize based on data
Remember: investing 2-4% of product value in quality packaging typically reduces damage-related costs by 10-20x. The question isn’t whether you can afford good packaging—it’s whether you can afford not to have it.
