Shipping Boxes from Montreal to Portland via Ocean Freight

For moisture-sensitive assorted consumer products, begin by 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. 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, 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 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 plastic tableware on top. Inside each carton, include 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 mixed cargo, select 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 containers, pack separately sharp-edged items so they do not cut into neighboring Miscellaneous items. 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, 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 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 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. 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.

When shipping mixed consumer goods, it is important to ensure proper packing and consolidation to prevent damage during transit. Mixed cargo may require special attention to weight distribution and securing to avoid shifting. Additionally, the variety of products may necessitate compliance with specific regulations regarding hazardous materials or food safety, depending on the contents.

Required documentation includes a bill of lading, commercial invoice, and a packing list. Importers must also comply with U.S. Customs and Border Protection regulations, which may require additional forms such as the Importer Security Filing (ISF) and any necessary permits for specific goods. Proper documentation is essential to facilitate smooth customs clearance.
