The multilateral agreement M322 concerns the carriage of UN 0335 and UN 0336 fireworks. Fireworks UN 0335 and UN 0336 may also be transported in certain quantities, but without needing to meet the requirements of the following sections of ADR: 126.96.36.199 (a), 9.1.2, 188.8.131.52, 184.108.40.206.5, 9.3.3 (second subparagraph), and 220.127.116.11 (second subparagraph).
Drivers must turn off heaters that do not comply with paragraph 18.104.22.168.5 during transportation of the fireworks, when unloading, loading and when handling the class 1 dangerous goods.
The exemption only applies to the following quantities of the class 1 dangerous goods:
Mixed loads of UN 0335 and UN 0336, shall not exceed 2,500Kg.
Loads of only UN 0336, shall not exceed 7,500Kg
Where this does not apply, all other relevant requirements of ADR should be conformed to. The consigner should include the following statement in their transport documents: “Carriage agreed under the terms of ADR paragraph 1.5.1 (M322)” and a copy of the agreement provided must be carried onboard the vehicle.
The agreement is valid until the 19th of August 2024 in the UK unless revoked. Please note that this does not apply to carriage through the Channel Tunnel.
