CN 7305Covered by CBAMIron & Steel

CN 7305 under CBAM — Large-Diameter Welded Pipes

Other tubes and pipes (e.g. welded, riveted), external diameter > 406.4 mm, of iron or steel

Large-diameter welded line pipe — LSAW, HSAW/spiral — for oil, gas and water transmission. India’s pipe majors in Gujarat export project quantities to EU energy and water infrastructure, where a single order can run thousands of tonnes: exactly the consignment size at which the gap between default-basis and verified-actuals CBAM cost becomes a contract-deciding number.

Emission profile

Where the emissions in CN 7305 come from

The pipe mill itself — forming, welding, coating — adds a modest increment; the heavy plate or coil it consumes is the dominant precursor, carrying BF-BOF steelmaking emissions. Defaults assume the conservative case for the whole chain. The EU default value for this heading is deliberately conservative; on project tonnages, verified actuals for the plate chain are worth serious money.

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.

What to do

Exporting under CN 7305? Three moves, in order.

01
Identify your production route and precursors
Trace the plate/coil supply chain — usually purchased from integrated mills, making it a precursor whose installation-level data you must obtain — then document your forming, welding and coating stages.
02
Collect the data you already have
Plate purchase records with mill traceability, welding consumable and energy logs, coating-line records, project-wise production data.
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.

Frequently asked

CN 7305 and CBAM, in plain English

Is CN 7305 covered by CBAM?

▼

Yes. CN 7305 — welded tubes and pipes above 406.4 mm external diameter, including LSAW and spiral line pipe — is a covered good under the EU Carbon Border Adjustment Mechanism. Any consignment under this heading imported into the EU has carried reporting obligations since the transitional phase (1 October 2023 – 31 December 2025), and since the definitive phase began on 1 January 2026 the EU importer must buy CBAM certificates against its embedded emissions. Project line pipe for EU energy and water infrastructure imports under this heading.

How much CBAM cost does CN 7305 face in 2026?

▼

CBAM certificates track the EU ETS carbon price — roughly €70–80 per tonne of CO₂ in 2026 — so the bill is your embedded emissions multiplied by that price. For Indian BF-route steel products the difference between bases is dramatic: default-basis costs run roughly €250–270 per tonne of product, versus roughly €65–170 per tonne on verified actuals — about €80,000–€180,000 on a single 1,000-tonne consignment. The exact figure depends on your route and product mix, which is why the first step is a proper calculation, not a guess.

CBAM on a pipeline project bid — who actually pays, and why should the mill care?

▼

The EU importer of record surrenders the certificates, but the cost lands in the project’s landed price — which is how bids are compared. Two Indian mills quoting the same pipe can differ by the entire defaults-vs-actuals gap in evaluated cost. Since the definitive phase began on 1 January 2026, EPC buyers have started asking for emission data at the bid stage; mills that can hand over a verified filing bid with a structurally lower landed price.

Our plate comes from multiple mills across orders. How is that handled?

▼

Per-precursor: each plate source’s embedded emissions are attributed to the pipe made from it, so a filing may combine several suppliers’ data (or defaults, where a supplier refuses). Keeping heat-number traceability from plate to pipe — which line-pipe quality systems already require — makes this workable. We build the attribution from your existing traceability records.
