Shipping Automotive Parts from Shanghai to San Juan via Ocean Freight

For moisture-sensitive automotive parts, select inner Moisture-barrier bags around each component, then place them in reinforced packaging with sufficient cushioning. Seal all seams with filament tape and clearly mark cartons “Dry Storage Only”. For export or long-duration transit, evaluate adding humidity control packs inside master cartons and, if needed, inside the shipping container.

You may ship vehicle tires with boxed Auto parts, but they must be physically separated and properly secured. Most carriers recommend palletizing boxed car parts and then stacking or racking car tires so they do not press against or rub cartons. Avoid placing heavy loose car tires on top of fragile or moisture-sensitive Automotive parts, as this can cause crushing or punctures during transit.

Fluid-filled automotive parts such as fuel system components, shock absorbers, or oil coolers often require Hazardous materials declarations, depending on the type and quantity of fluid. Exporters should review whether the product is classified as dangerous goods under relevant transport regulations and include the appropriate safety data sheets (SDS), UN numbers, and packing group information if applicable. Even when not regulated as hazardous, clearly mark “Contains Fluids – Keep Upright” on packaging and shipping documents to guide carriers.

High-value auto components such as engines, transmissions, ECUs, and safety modules should be shipped with Full-value cargo insurance. Carrier default liability tends to be limited and may not cover the full replacement cost of specialized auto parts. Freight experts recommend insuring based on replacement value, documenting serial numbers and condition at pickup, and retaining invoices and packing lists so any claim for loss, impact damage, or moisture-related failure is processed efficiently.

To reduce damage in mixed auto parts pallet loads, position the heaviest metal components at the bottom, with lighter boxes and Tires above. Use angle boards, banding and film wrap to stabilize the load and prevent shifting. Keep moisture-sensitive vehicle parts toward the center of the pallet, away from potential leaks or condensation on trailer walls, and prominently mark any fragile or orientation-sensitive cartons so handlers will follow correct handling procedures.
