Hydrogen
The single code makes a sector of its own. The weight declared is the net weight of the gas, excluding cylinders, trailers and tanks, under regulation 4 of SI 2026/802.

- Emissions treatment
- The net weight of the good multiplied by the Treasury default value under regulation 4 of SI 2026/995, or by the installation's verified emissions intensity under regulation 5.
The checker applies the Table to any eight-digit code. Whether goods are correctly classified under a code is a customs question under paragraph 2(2) of Schedule 16, and the code on the customs declaration decides.
The threshold calculator says when the customs value of covered imports triggers registration, the guide on actual data and default values says how the emissions are determined, and the relief guide says how a carbon price paid abroad reduces the tax.
