International Cargo Packing Guide: Standard Rules & Best Practices
Professional cargo packing directly affects shipping safety, customs passing rate, and transportation cost. Improper packaging is the main cause of cargo damage, leakage, and transit delays. This guide introduces international standard packing rules for sea freight, air freight, and cross-border shipping.
Basic International Packing Standards
Stable and Compressive Packaging
Cartons must be strong enough for stacking, especially for LCL sea freight and warehouse storage.
Sealed and Moisture-Proof
Use waterproof film, bubble wrap, and moisture-proof paper to avoid damp damage during long-distance shipping.
Clear Marking
All individual shipping packages are required to be clearly printed with complete shipping marks, detailed destination delivery information as well as the exclusive serial number assigned to each respective package.
Reasonable Weight Distribution
It is necessary to prevent individual parcels from exceeding the standard weight limit, since overweight single packages are prone to sustaining various physical damages in the course of cargo sorting, loading, unloading and all other routine logistics handling operations.
Packing Requirements for Different Cargo Types
General Goods
All products should be packed in standard cartons and fully sealed with packing tape.
Fragile Items
Pack goods with reinforced cartons and bubble wrap, and mark fragile labels outside packages.
Electronics & Sensitive Goods
Anti-static packaging, shockproof protection, and independent inner box packaging.
Oversized & Heavy Cargo
Wooden box packing or pallet fixing to prevent deformation and falling.
FAQ
Q: Do I need pallet packing for sea freight?
A: For LCL shipments, pallet packing is highly recommended to reduce damage and improve loading efficiency.
Q: Can I use old cartons for international shipping?
A: Only undamaged, clean, and strong cartons are allowed. Broken or deformed boxes are not suitable for international transport.
Shipping documents are the core basis for customs clearance, cargo pickup, and freight verification. Missing or incorrect documents will directly cause shipment failure and delays. This guide summarizes all essential shipping documents and standard requirements for global logistics.

Bill of Lading / Air Waybill
