Shipping Mixed Cargo from Manzanillo to Houston via Ocean Freight

For moisture-sensitive mixed cargo, first using sturdy, double-wall cartons sized closely to the contents. Line each box with a poly sleeve and seal it before closing the carton. Most shippers recommend separating plastic tableware and other fragile miscellaneous items with dividers or bubble wrap, then filling voids with paper or foam so nothing moves. Finally, protect the palletized load with stretch film, including a top sheet, to reduce exposure to humidity and light rain during handling.

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

For medium-weight assorted products, use 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 containers, pack separately sharp-edged items so they do not cut into neighboring variety goods. On pallets, apply corner protectors and strapping to keep the load square and stable, especially for mixed consumer goods moving through multiple hubs.

In most cases, travel kits shipped with other assorted consumer products 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 plastic tableware. 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, verify with your carrier for additional dangerous goods documentation and packing rules.

Store containers and boxes 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 single-use items. Our team recommends 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.

Mixed Consumer Goods require careful packing and securing to prevent damage during transit. It's essential to ensure that the cargo is properly consolidated and labeled for easy identification at both ports. Additionally, some items may require specific handling due to their nature, such as fragile or temperature-sensitive products.

Required documentation includes a bill of lading, commercial invoice, packing list, and any necessary customs forms. Importers must also ensure compliance with U.S. Customs and Border Protection regulations, which may include specific declarations for certain consumer goods.

Our system includes Document Intelligence and a Smart Document Hub that auto-tags and organizes bills of lading, customs forms, and invoices, parses and sorts every invoice, BOL, and customs document, and makes it easy for your team to find the right file quickly.
