4DV Frequently Asked Questions

4DV packaging is made from plywood and is designed to provide a sturdy and inflexible outer packaging solution for the transportation of hazardous goods.

Plywood is a great choice for shipping crates, as it provides a strong and rigid protective barrier for transporting large, heavy or fragile dangerous goods. This includes added impact protection, resistance to temperature variations, and general shipping conditions, keeping your products safe during transport.

4DV shipping boxes are also an environmentally friendly solution, as they are easy to recycle, feature water-based ink, and have PEFC certification.

The 4DV plywood box range offers a unique blend of flexibility and durability, making it suitable for a wide range of hazardous products. 4DV boxes have been UN approved, so they are specifically constructed to be suitable for transporting dangerous heavy goods according to the relevant transport regulations.

Air Sea USA range of 4DV boxes can handle an impressive maximum permitted weight of 120kg (inner packaging and substance) and a gross package weight of 280kg.

This all depends on the inner packaging that you’re placing inside the 4DV Plywood box.

Vermiculite is the approved cushioning material that must be used in all Air Sea USA 4DV boxes, as it was the cushioning material used during the UN approval testing process for each 4DV box. It should not be replaced with alternative cushioning material.

Vermiculite is lightweight, inert (non-reactive) and is often used when transporting flammable, corrosive and hazmat fragile items. It is ideal for cushioning items as it is compressible and absorbent, which enables voids to be filled to the required standards.

If you’re unsure about how much vermiculite to use for your packaging, then please contact us, and we can advise you.
