Shipping Packaging Materials from Yokohama to Tacoma via Ocean Freight

For moisture-sensitive assorted consumer products, first using sturdy, double-wall cartons sized closely to the contents. Line each box with a moisture-barrier bag and seal it before closing the carton. Our team suggests separating tableware and other fragile miscellaneous items with dividers or bubble wrap, then filling voids with paper or foam so nothing moves. Finally, cover the palletized load with stretch film, including a top sheet, to reduce exposure to humidity and light rain during handling.

Yes, you can ship disposables with heavier general merchandise, but you need to control how they are combined. Place heavier cartons at the bottom of the pallet and lighter boxes with travel kits on top. Inside each carton, add inner boxes or dividers so sharp or rigid items do not deform softer plastics. Our logistics team recommends limiting stack height and marking “Do Not Crush” when mixed cartons contain fragile plastic tableware or thin packaging materials.

For medium-weight mixed cargo, use double-wall boxes that can handle stacking in trucks or containers. Smaller, well-filled cartons generally perform better than oversized boxes with lots of empty space. For shipments that include cartons and boxes, isolate sharp-edged items so they do not cut into neighboring Miscellaneous items. On pallets, Use corner protectors and strapping to keep the load square and stable, especially for mixed consumer goods moving through multiple hubs.

In most cases, in-flight products shipped with other assorted consumer products only require standard commercial documentation, but accuracy is important. Shippers should list each product group separately on the commercial invoice and packing list, indicating quantities and weights for items like disposables. Use clear, non-technical descriptions and add handling marks such as “Keep Dry” or “Fragile” where appropriate. If any component of the travel kits (for example, aerosols or batteries) is regulated, check with your carrier for additional dangerous goods documentation and packing rules.

Store packaging supplies and other variety goods in a clean, dry area away from direct sunlight and open dock doors. Keep cartons on pallets or shelving rather than directly on the floor to avoid moisture wicking into boxes, especially for moisture-sensitive disposables. Most warehouses recommend maintaining good airflow and using dehumidifiers or desiccant where humidity is high. Rotate stock so older boxes and plastic goods are used first, ensuring they retain enough strength for safe stacking and transport.
