Hazardous Goods UN Crate

危包木箱

For dangerous goods the difficulty is not crate strength but the compliance chain: box type code, certification level, barrier lining and hazard labelling must each match the cargo and the mode of transport. A single mismatch can block customs clearance or lead to rejection by the carrier. Hazmat crates are designed against the UN box-type requirements, with body, lining and fasteners specified as a matched set.

FAQ

Frequently Asked Questions

What does UN 4D mean?

UN transport regulations identify packaging by a letter-and-number code: the leading digit 4 denotes a box, and the following letter denotes the material — 4D specifically designates a plywood box. "UN 4D" therefore describes the packaging type. Whether it is acceptable for a given substance still depends on its hazard class, packing group and certification level.

What packaging conditions apply to exporting lithium battery racks?

Lithium batteries are dangerous goods, and packaging must meet the UN transport regulations applicable to the relevant UN number — typically involving box certification, protection against short circuit and inadvertent activation, and a lining designed to contain leakage or thermal propagation. The applicable provisions vary with state of charge and mode (sea or air), and must be confirmed per shipment against the actual cargo parameters.

How is the leakage barrier achieved?

The crate uses a fully enclosed body with a dedicated moisture and leakage barrier cushion lining, and the joints are secured with reinforced metal clasps. Lining material is selected for chemical compatibility with the contents. Where the cargo is corrosive or requires thermal control, additional barrier layers are specified to suit the actual conditions.

Can you support the packaging documentation required for customs export?

The company holds customs authorisation for the application of wood packaging treatment marks, registration CN51188, and can support exports subject to wood packaging quarantine requirements. Dangerous goods packaging also involves performance and use certification stages; the exact documents required vary with the substance and destination, so the checklist should be confirmed in advance.
