CN 7306 under CBAM — Welded Tubes & Hollow Sections

Other tubes, pipes and hollow profiles, welded, of iron or steel

ERW tubes, precision tubes and structural hollow sections up to 406.4 mm — India’s highest-volume welded-tube heading, produced from HR or CR strip by mills across the country and exported to EU construction, furniture, automotive and general engineering buyers.

Emission profile

Where the emissions in CN 7306 come from

An ERW mill’s own energy footprint is light; the strip it forms and welds is the precursor that carries the steelmaking emissions, off BF-BOF or the secondary route. Defaults ignore the strip’s real origin. The EU default value for this heading is deliberately conservative — tube makers with cooperative strip suppliers routinely have a much better verified number available.

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 7306? Three moves, in order.

  1. 01

    Identify your production route and precursors

    Identify your strip supply: which mills, which route, and whether galvanised feed or post-galvanising is involved — the strip is a precursor requiring supplier emission data.

  2. 02

    Collect the data you already have

    Strip purchase invoices with coil traceability, tube-mill electricity records, galvanising-bath fuel data where applicable, production logs by section size.

  3. 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 7306 and CBAM, in plain English

Is CN 7306 covered by CBAM?

Yes. CN 7306 — welded tubes, pipes and hollow profiles of steel up to 406.4 mm, including ERW tube and structural hollow sections — 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. Square and rectangular hollow sections for EU construction fall under this heading.

How much CBAM cost does CN 7306 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.

We galvanise our tubes after forming. How does that enter the CBAM number?

The galvanising stage’s fuel and electricity at your installation are counted within your product’s boundary, on top of the strip precursor’s embedded emissions. It is a real but secondary contributor — the strip still dominates. What matters is that the boundary is complete and consistent; a filing that silently omits the galvanising bath is the kind of gap an EU verifier flags.

Several EU buyers, several declarants — do we prepare CBAM data separately for each?

The underlying installation-level calculation is done once per reporting period; each buyer’s Authorised Declarant then receives the data for their consignments in the format they need. This is exactly the coordination CarbonSettle runs — one verified data set, delivered to every declarant, with verifier queries handled centrally so your sales team never becomes a CBAM helpdesk.
