Shipping Boxes from San Juan to Seattle via Ocean Freight

For moisture-sensitive General merchandise, Start by using sturdy, double-wall cartons sized closely to the contents. Line each box with a poly sleeve and seal it before closing the carton. We recommend separating Kitchen accessories and other fragile miscellaneous items with dividers or bubble wrap, then filling voids with paper or foam so nothing moves. Finally, Wrap the palletized load with stretch film, including a top sheet, to reduce exposure to humidity and light rain during handling.

Yes, you can ship Plastic goods with heavier Other goods, but you should control how they are combined. Place heavier cartons at the bottom of the pallet and lighter boxes with Plastic products on top. Inside each carton, Use inner boxes or dividers so sharp or rigid items do not deform softer plastics. We recommend limiting stack height and marking “Do Not Crush” when mixed cartons contain fragile plastic tableware or thin packaging materials.

For medium-weight Consolidated goods, Choose export-strength 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 Packaging materials, Separate sharp-edged items so they do not cut into neighboring Miscellaneous items. On pallets, add corner protectors and strapping to keep the load square and stable, especially for mixed consumer goods moving through multiple hubs.

In most cases, Airline supplies shipped with other General merchandise only require standard commercial documentation, but accuracy is important. Exporters should list each product group separately on the commercial invoice and packing list, indicating quantities and weights for items like Packaging supplies. 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, Consult your carrier for additional dangerous goods documentation and packing rules.

Store Packaging materials and other Miscellaneous items 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 single-use items. We 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.

Shipments from San Juan to Seattle require a bill of lading, commercial invoice, and a packing list. Additionally, since Puerto Rico is a U.S. territory, no specific customs duties are required, but compliance with U.S. regulations is necessary.

Seasonal considerations include potential weather-related disruptions, such as hurricane season from June to November, which may affect shipping schedules and port operations in both San Juan and Seattle.
