Seven Common Pallet Types for Import, Export and Container Shipping

1. Rotationally molded plastic pallets

Rotational molding can suit large plastic pallets with relatively simple designs. Reinforcement options, cleaning and load limits depend on the model. Compare tooling, order quantity, service life and return logistics when assessing cost; the process alone does not prove a lower price.[3]

Selection check：For food or pharmaceutical projects, verify material suitability, cleaning validation and customer requirements. The process name is not a hygiene certification.

2. Injection molded pallets, including HDPE

Injection molding supports repeatable production. HDPE, or high-density polyethylene, is one common material, alongside other resin options. Decks may be open or closed; entry depends on design. Washing, chemical resistance and recyclability depend on resin, exposure, temperature and local collection arrangements.[3][4]

Selection check：For warehouse and returnable systems, check openings, bottom supports and compatibility with forklifts, pallet jacks and automation.

3. Block pallets: commonly four-way entry

Blocks connect the upper deck to the lower structure. This commonly enables four-way entry, but block count, bottom boards and clearances vary. A block pallet is not defined by twelve posts, and a deck-board construction is not a synonym for block construction. Bottom boards can limit some equipment access.[1]

Selection check：Confirm usable openings in every direction and distinguish forklift access from pallet-jack access.

4. Stringer pallets: two-way unless designed otherwise

Continuous stringers support the deck. Conventional unnotched designs normally allow entry at the two ends. Notches can provide side access for forklifts, without necessarily allowing four-way pallet-jack access. Strength depends on materials, member sizes, connections and service conditions; stringers are not automatically stronger than blocks.[1][2]

Selection check：Useful shorthand: blocks commonly allow four-way entry; unnotched stringers commonly allow two-way entry. Always check notches, bottom boards and equipment.

5. Double-face pallets: not always reversible

A double-face pallet has both top and bottom decks. It may be reversible or nonreversible. Only a design confirmed as reversible allows either face to serve as the load-carrying surface. A bottom deck alone does not establish capacity.[1][2]

Selection check：Specify reversibility explicitly and check the bottom deck against handling and rack arrangements.

6. Double-wing pallets: projecting decks

Double-wing describes top and bottom decks extending beyond the stringers or supports. It does not automatically imply a higher payload, permission for cargo overhang or a one-way shipping design. Reuse and any lifting arrangements require separate confirmation.[2]

Selection check：Check the projecting edges, cargo support and overall dimensions; use the outermost dimensions in the container layout.

7. Solid-deck pallets: continuous or closed top surfaces

A solid or closed deck avoids an open slatted top and can provide more continuous support for small packages. It may use a panel or molded construction, rather than a single solid-wood board. Cleaning, drainage, grip and ventilation depend on the actual design and material.[1][4]

Selection check：Small items still need suitable packaging and restraint. A closed deck does not replace stable unit-load design.

Entry direction: check both construction and equipment

Four visible openings do not prove usable four-way access. Opening height, fork thickness, bottom boards and pallet-jack wheels affect compatibility. Request opening dimensions, approved equipment and access directions, especially for notched stringers.

Before loading a container

• Dimensions: plan with the actual container interior, door opening and pallet envelope instead of a universal pallets-per-container number.
• Load cases: distinguish static, dynamic and racking ratings, including test and support conditions.
• Container limits: verify unit gross weight, centre of gravity, payload and floor or concentrated-load limits; distribute weight appropriately.
• Equipment: confirm forklifts, pallet jacks, racks and conveyor compatibility.
• Restraint: agree suitable blocking, dunnage, lashing or other securing measures; stretch wrap alone does not resolve overhang or loading gaps.
• Wood packaging: check destination ISPM 15 treatment and marking requirements for regulated solid wood. Wholly processed-wood packaging and mixed construction with raw-wood components require different assessment.[5]
