Sourcing boron steel wire rod from China
Boron steel wire rod from China has 0% duty within an available steel quota and 50% outside it, plus 24.00% residual anti-dumping duty. Classify hot-rolled coils by their full chemistry and delivery form. Cambridge China Bridge sources boron steel wire rod.
Boron wire rod duty and anti-dumping
Read from the UK Trade Tariff on 29 September 2026, heading 7227 covers hot-rolled bars and rods of other alloy steel in irregularly wound coils. The dedicated boron composition line is 7227 90 10 00. This guide covers that line; other compositions are discussed in our alloy steel wire rod guide.
The supplied boron line lists 50% third-country duty and 24.00% residual anti-dumping duty for China, with a steel measure. An available tariff-free quota removes the steel duty, but anti-dumping remains payable and cumulates with steel duty outside quota. No countervailing duty, suspension or attached import control is recorded. Ask your broker to check quota availability and any producer-specific rate before ordering.
Confirm the commodity code from the complete mill chemistry, hot-rolled condition and coil form. A boron grade name alone is insufficient. The illustrative order values are not a landed-cost quotation; include anti-dumping duty when budgeting and use the import duty and VAT guide.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Hot-rolled boron steel wire rod meeting the tariff composition definition | 7227 90 10 00 | 50% outside quota | 24.00% residual anti-dumping |
Boron chemistry, forming and heat treatment
Specify the intended process, such as wire drawing followed by cold heading or heat treatment. Agree the steel grade, full chemical composition, delivery condition, rod diameter and ovality tolerance. Ask the mill to report boron alongside carbon and the other alloying elements, with results linked to each heat.
Agree surface-defect and decarburisation acceptance criteria for the intended finished part. Record coil weight, inside and outside diameter, winding condition and packaging so the material fits your handling and pay-off equipment. Approve a trial through your own drawing, forming and heat-treatment process before accepting bulk material.
Inspection checklist
Traceability: match coil tags and heat numbers to the packing list and mill chemistry records; investigate mixed or untraceable heats.
Dimensions: measure rod diameter and ovality on sampled coils; check coil dimensions and winding against your handling equipment.
Surface: inspect for seams, laps, rust and heavy scale; arrange checks against the agreed decarburisation criteria.
Performance: verify the agreed chemistry and mechanical results on representative samples; assess drawing, forming and hardening behaviour using the intended process.
What goes wrong
A supplier's boron steel description can conceal chemistry that belongs under another tariff line. A quotation that assumes quota relief or omits anti-dumping can understate import costs. A lower specified-exporter rate needs the prescribed invoice and declaration; without either, the residual rate applies.
Surface seams can open during drawing or heading, while inconsistent chemistry or decarburisation can affect hardening results. Tangled coils interrupt feeding, and lost heat tags make disputes harder to resolve. Agree rejection criteria, preserve heat identity and use factory verification to check the mill's records and production capability.

Frequently asked questions
What is the UK import duty on boron steel wire rod from China?
The supplied line 7227 90 10 00 lists 50% duty outside steel quota and 24.00% residual anti-dumping duty. Available tariff-free quota removes the steel duty, but anti-dumping remains payable.
Is boron wire rod the same as cold-heading wire?
Check the delivered condition. This guide covers hot-rolled rod in irregularly wound coils. A cold-heading use does not establish whether the supplied material is hot-rolled rod or finished drawn wire.
Which mill records should I request for boron wire rod?
Request heat-linked chemistry, including boron and other alloying elements, delivery condition and agreed mechanical results. Match every coil tag to the records and agree independent sampling where needed.
How do I check whether boron wire rod suits my process?
Trial representative material through your drawing, heading and heat-treatment process. Check surface defects, decarburisation, dimensional consistency and finished-part performance against agreed acceptance criteria.
