CN 7318 under CBAM — Fasteners

Screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, washers and similar articles, of iron or steel

Fasteners — screws, bolts, nuts, rivets and washers — one of India’s signature engineering exports, from the Ludhiana and Rajkot clusters to EU automotive, construction and industrial distributors. High piece counts, modest tonnage per shipment, and since 1 January 2026 every kilogram needs an embedded-emissions figure behind it.

Emission profile

Where the emissions in CN 7318 come from

Fasteners are cold-forged or hot-forged from wire rod and bar — precursors that carry the steelmaking emissions of their route (integrated BF-BOF or the secondary DRI + induction route common in North India). Forming, heat treatment and plating add measured, mostly electrical energy. The EU default value for this heading is deliberately conservative; a fastener maker’s real chain — documented rod source plus efficient forming — is usually a far better number, but only verified actuals make it count.

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 7318? Three moves, in order.

01
Identify your production route and precursors
Identify the steel behind your fasteners: which rod and bar suppliers, off which route — the precursor is most of your number. Note heat-treatment and plating lines as in-boundary stages.
02
Collect the data you already have
Rod/bar purchase invoices with traceability, cold-heading and threading machine electricity data, heat-treatment furnace fuel and power logs, plating-line records, production weights by family.
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 7318 and CBAM, in plain English

Is CN 7318 covered by CBAM?

▼

Yes. CN 7318 — screws, bolts, nuts, rivets, washers and similar fasteners of iron or steel — 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. India’s Ludhiana and Rajkot fastener clusters export to the EU squarely under this heading.

How much CBAM cost does CN 7318 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.

Fasteners are sold by the piece, not the tonne. How does a per-tonne carbon cost reach us?

▼

Through the landed-cost comparison your EU distributor runs. CBAM certificates are surrendered against the tonnes of steel in your shipment at roughly €70–80 per tonne of CO₂ embedded, and the resulting cost per container gets divided back into piece prices. On defaults that markup is at its conservative maximum; on verified actuals it reflects your real chain — typically up to ~40% lower. For a commodity as price-compared as fasteners, that spread decides orders.

We buy wire rod from three mills and job-work some plating out. Is a verified filing even feasible?

▼

Yes — this is a normal fastener-cluster configuration. Each rod mill is a precursor line (their data or defaults, per supplier), your forming and heat treatment are metered in-house, and job-worked plating is bounded from the job-worker’s energy records or handled per the methodology’s rules for outsourced steps. CarbonSettle maps the chain, chases the suppliers and delivers the verified filing — your team’s effort is mostly handing over documents you already keep.
