Selection and Standards for Ocean Shipping Packaging
The packaging method for export and domestic ocean freight directly affects transportation safety and logistics costs. This article compares the applicable scenarios, level of protection, and fumigation requirements of five mainstream packaging methods, and provides packaging labeling standards for shippers' reference.
1. Comparison of Five Mainstream Packaging Methods
| Packaging Method | Suitable Cargo | Protection Level | Export Fumigation Requirements |
|---|---|---|---|
| Carton | Light industrial products, consumer goods, electronics | Medium | Not required |
| Wooden Case | Heavy goods, precision equipment, machinery | High | Required (IPPC mark) |
| Pallet | Standardized goods | Medium-High | May be required |
| Iron Drum / Plastic Drum | Liquids, chemical products | High | Not required |
| Bundled / Rolled | Steel, plates, textiles | Medium-Low | Not required |
2. Carton Packaging
| Element | Requirement |
|---|---|
| Carton material | Three-layer corrugated (light goods) or five-layer corrugated (heavy goods) |
| Maximum weight per carton | Recommended not to exceed 25 kg |
| Sealing method | H-shaped sealing (add a strip of sealing tape in the middle) |
| Stacking layers | Up to 6-8 layers |
| Moisture-proof treatment | Add a plastic bag or moisture-absorbing beads inside |
| Marking | Carton number, product name, gross weight, dimensions, "Fragile" label |
3. Wooden Box Packaging and Fumigation Requirements
Technical Key Points
| Item | Requirement |
|---|---|
| Wood type | Plywood (fumigation-free) or solid wood (fumigation required) |
| Base board thickness | ≥15mm (heavy goods require reinforcement) |
| Waterproofing treatment | Lined with waterproof membrane or felt |
Fumigation Requirements
Solid wood packaging exported to the following countries or regions must undergo fumigation treatment and be affixed with the IPPC mark:
| Country / Region | Requirement | Plywood Exemption |
|---|---|---|
| EU | Mandatory fumigation + IPPC mark | Fumigation-free |
| United States | Mandatory fumigation + IPPC mark | Fumigation-free |
| Canada | Mandatory fumigation + IPPC mark | Fumigation-free |
| Australia | Most stringent; quarantine declaration required | Quarantine declaration required |
| Japan | Mandatory fumigation + IPPC mark | Fumigation-free |
Material selection recommendation: Plywood wooden boxes are generally fumigation-free, while solid wood wooden boxes for export must be fumigated and affixed with the IPPC mark according to the destination country's requirements. Consult a professional freight forwarder for specific processing requirements and lead times.
4. Pallet Transport
Common Pallet Specifications
| Specification | Purpose |
|---|---|
| 1200 × 1000mm | International standard (ISO standard) |
| 1200 × 800mm | European standard (EUR pallet) |
| 1100 × 1100mm | Japan/Korea standard |
| 48" × 40" | American standard (GMA pallet) |
Loading Recommendations
- The height of goods on a single pallet is recommended not to exceed 1.5m
- A 20GP container can hold approximately 10 standard pallets
- A 40GP / 40HQ container can hold approximately 20-24 standard pallets
5. Packaging Labeling Requirements
All export cargo packaging must include: consignee information, gross/net weight, dimensions, carton number (e.g., 1/20), destination, and handling marks (fragile / this side up / keep dry, etc.). Clear and complete markings can reduce communication costs during sorting and inspection at the destination port.

Common Questions About Ocean Shipping Packaging (FAQ)
Q: What is the most suitable packaging for sea freight?
A: It should be chosen based on the cargo characteristics: light industrial products and consumer goods use cartons; heavy goods and precision equipment use wooden cases; liquids and chemicals use iron or plastic drums; standardized goods use pallets. In addition, fumigation and IPPC markings must be considered according to the requirements of the destination country.
Q: What is the IPPC mark?
A: The IPPC mark is the treatment mark recognized by the International Plant Protection Convention for wooden packaging. Export solid wood packaging must undergo quarantine treatment such as fumigation and be affixed with this mark; otherwise, it may be refused entry or required to be returned at the destination country's customs.
