What are Dangerous & Sensitive Goods?
Products containing lithium-ion batteries, liquid contents, fine powders, cosmetics, magnetic components, or sharp items are classified as 'sensitive goods' (敏感货) by international air freight companies. Shipping these items via standard e-commerce shipping lines triggers immediate security scan failures, leading to package return holds and customs penalties.
Sourcing Classification of Sensitive Cargo
Ensure you understand the specific shipping requirements for your product category before ordering from 1688:
- Lithium Batteries (PI967 & PI966): Battery built inside the device (e.g., smartwatches) is PI967, which is easier to ship. Battery packed separately beside the device (e.g., replacement batteries) is PI966, requiring strict fire-retardant outer packages.
- Magnetic Products: Speakers, motors, and magnetic closures require a magnetic inspection certificate (磁检报告) to verify the magnetic field does not interfere with aircraft navigation systems.
- Liquids & Creams: Essential oils, creams, and gels require a Safe Transport Certificate (液体运输安全鉴定书) and double-bag leak-proof sealing.
Sensitive Line vs. General Air Line Comparison
| Cargo Route Type | Average Transit Time | Surcharge / kg | Customs Hold Rate |
|---|---|---|---|
| Special Sensitive Line (DG) | 8 - 12 Days | +$1.50 - +$2.50 | < 2% (Pre-Cleared via HK) |
| General Air Line | 5 - 8 Days | +$0.00 | > 95% (Rejected at x-ray scan) |
Obtaining MSDS & UN38.3 Certificates
When sourcing battery-powered electronics, copy and paste this negotiation message to your 1688 manufacturer sales chat before wire transfer:
If the supplier cannot provide updated certificates, avoid placing bulk orders, as your logistics agent will be unable to clear air customs.
