CBAM data for steel tube and pipe exporters

Tube and pipe makers get some of the most detailed CBAM requests. Whether you make seamless or welded tube changes where the numbers come from.

Quick answer

Seamless (CN 7304) and welded (CN 7305, 7306) steel tubes and pipes are CBAM goods. Only direct emissions count, such as reheating and heat-treatment furnaces. The billets or hot-rolled coil you buy are precursors and usually make up most of the figure.

Is this product covered by CBAM?

Yes. Seamless tubes and pipes (CN 7304) and welded tubes and pipes (CN 7305 and 7306) are within CBAM's iron and steel sector.

CN codeGoods
7304Seamless tubes, pipes and hollow profiles
7305Other tubes and pipes, external diameter over 406.4 mm
7306Other tubes, pipes and hollow profiles, welded and others
7207 / 7208Billets or hot-rolled coil, the usual precursors

Always confirm the exact code your buyer declares your goods under. Scope is set by CN code, not by how the product is described.

What counts toward your figure

Most iron and steel goods are on the CBAM list where only direct emissions count in the definitive period. Electricity used in your plant isn't part of the CBAM figure, even if the template asks you to report it.

Direct emissions at a typical tube mill come from:

  • Billet reheating furnaces before piercing (seamless)
  • Heat-treatment and normalising furnaces
  • Fuel for galvanising bath heating, if you galvanise
  • Any on-site fuel for drying and coating

Your precursors: usually the biggest number

Seamless mills pierce and roll steel billets or rounds; welded mills form and weld hot-rolled coil or plate. Both precursors are CBAM goods with their own embedded emissions, usually far larger than your own. Zinc used for galvanising isn't a CBAM precursor.

What your buyer will ask for

  1. Embedded emissions per tonne for each tube code
  2. Seamless or welded route
  3. Billet, coil or plate suppliers and countries of origin
  4. Whether figures are actual and verified

Documents to gather

  • Fuel invoices per furnace
  • Production by product and route
  • Billet, coil and plate purchase invoices
  • Scrap, crop-end and yield records

Common mistakes

  • Using one figure for seamless and welded products
  • Counting electricity for forming and welding
  • Leaving out crop ends and yield losses when relating input to output
  • Treating zinc as a CBAM precursor

Frequently asked questions

Are steel pipes covered by CBAM?

Yes. Seamless and welded steel tubes and pipes (CN 7304, 7305 and 7306) are CBAM goods.

What is the precursor for welded pipe?

The hot-rolled coil or plate you form and weld, with its producer's embedded emissions or the default value.

Does galvanising zinc count?

Zinc isn't a CBAM precursor. Fuel used to heat the galvanising bath counts as your direct emissions.
