CN 7304 under CBAM — Seamless Tubes & Pipes
Tubes, pipes and hollow profiles, seamless, of iron (other than cast iron) or steel
Seamless tubes and pipes — boiler tubes, OCTG, precision and mechanical tubing — pierced and rolled from solid billet rather than welded from strip. Indian seamless makers in Maharashtra and Gujarat export high-value tonnage to EU energy, boiler and engineering buyers, where certification and now CBAM documentation travel together.
Where the emissions in CN 7304 come from
A seamless mill’s own stages (rotary piercing, reheating, heat treatment) are energy-hungry, and the round billet feeding them is a precursor carrying the steelmaking emissions — BF-BOF or electric route. Defaults assume the conservative end of all of it. The EU default value for this heading is deliberately conservative; the route split and billet chain are exactly what verified actuals put right.
Why we don’t print a default value here
The EU publishes and updates specific default values per goods category separately — quoting a stale number would mislead you. What never changes: defaults are set deliberately high, and the markup escalates from 10% in 2026 to 30% by 2028 for steel and aluminium (free-allowance phase-out runs to 2034). Use the CBAM calculator for a current, product-specific estimate.
Exporting under CN 7304? Three moves, in order.
- 01
Identify your production route and precursors
Map billet supply (own melt or purchased — a precursor) and the route behind it, then your own mill stages: piercing, reheating, sizing, heat treatment.
- 02
Collect the data you already have
Reheating and heat-treatment furnace fuel records, mill electricity bills, billet purchase documentation with supplier emission data, production logs by size range.
- 03
File verified actuals, not defaults
Have the numbers computed to the EU CBAM methodology and verified, then hand your EU buyer’s Authorised Declarant a filing they can use. Verified actuals typically cut the CBAM cost by up to ~40% versus default values — and the default markup only gets worse, escalating from 10% in 2026 to 30% by 2028 for steel and aluminium.
