Shipping Industrial Chemicals from San Juan to Shanghai via Ocean Freight

Shipping moisture-sensitive Chemical products necessitates high-integrity packaging, foil or poly liners, and drying agents inside cartons or overpacks. Shippers should also indicate “Keep Dry” on labels and booking notes and not use open or vented storage and transit equipment where humidity can build up.

For most regulated Industrial chemicals, UN-certified packaging must be used when shipping by road, sea, or air. The applicable UN packaging code and performance level are based on the product’s hazard class and packing group shown on the SDS. Be sure to confirm with your dangerous goods specialist or carrier whether your industrial chemicals are fully regulated, limited quantity, or exempt before selecting packaging.

Most Chemical goods shipments Require a DG shipping paper, the latest SDS, and correct labels and markings that align with the classification. Our team recommends including emergency contact details, handling instructions (e.g., “Keep Dry,” “Do Not Stack”), and any licenses required by local authorities for specific chemical goods.

You Can often consolidate different Specialty chemicals, but only if regulatory separation requirements are met. Carefully verify the SDS and relevant ADR/IMDG/IATA tables to ensure acids, bases, oxidizers, flammables, and other chemical products are properly separated. Use physical barriers and clear labeling when combining multiple hazard classes.

Because Chemical products can cause Costly cleanup if leaks occur, enhanced freight insurance is often required by buyers. Always review your policy to confirm that dangerous goods and specialty chemicals are not excluded, and that coverage covers contamination, disposal, and emergency response costs where applicable.

When shipping chemicals, it is essential to adhere to specific handling requirements, including proper packaging to prevent leaks, labeling with appropriate hazard symbols, and ensuring compliance with international maritime regulations for hazardous materials.

Regulatory requirements include obtaining the necessary export permits from Puerto Rico, ensuring compliance with China's import regulations for hazardous substances, and providing accurate documentation such as Safety Data Sheets (SDS) and customs declarations.
