Sourcing silicon-manganese rod from China
Silicon-manganese spring steel wire rod from China has 0% ordinary UK duty plus 24.00% residual anti-dumping duty. Classify by mill chemistry and hot-rolled coil form, rather than the spring grade name; drawn wire needs a separate code. Cambridge China Bridge sources silicon-manganese spring steel wire rod.
Duty on silicon-manganese spring steel wire rod
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. Silicon-manganese wire rod falls under 7227 20 00 00 when its chemistry and form meet that description. This guide concerns feedstock for spring manufacture. For the other steel families, see our alloy steel wire rod guide.
The supplied line lists 0% third-country duty for goods from China, plus 24.00% residual anti-dumping duty. It is not marked for the steel measure. No countervailing duty, suspension or attached import control is recorded for this line. A lower specified-exporter anti-dumping rate needs the qualifying commercial invoice and declaration; without the invoice or declaration, the residual rate applies.
Confirm the commodity code from the heat chemistry, processing history and delivery form. Include the commodity code on your import declaration. A supplier's spring steel grade name alone does not establish classification. The illustrative order values exclude anti-dumping and VAT; use our import duty and VAT guide when checking the full landed cost.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |

Spring chemistry, decarburisation and drawing trials
Specify the spring application and the drawing, forming and heat treatment processes the rod will undergo. Agree the steel grade and chemical limits, including carbon, silicon and manganese, together with delivery condition, diameter and ovality. Request heat-linked mill records rather than a generic grade certificate.
Agree surface seam and decarburisation acceptance limits, sampling locations and the method for checking disputed results. Record coil weight, inside and outside dimensions, winding and packaging requirements for your handling equipment. Trial representative material through drawing and spring manufacture before accepting the production lot.
Worked duty example
Illustrative example, not a quote: Illustrative order: 20 tonnes of silicon-manganese spring steel wire rod under 7227 20 00 00, invoiced at £18,000 free on board, with £2,000 of freight and insurance to the UK. The customs value is £20,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £20,000, so it is £4,000. With no duty, the only import tax is the VAT, which a VAT-registered importer can usually reclaim. The import duty and VAT guide explains each step.
Inspection checklist
Identity: match coil tags and heat numbers to the packing list and mill chemistry records; investigate mixed heats.
Dimensions: check rod diameter and ovality at sampled positions, plus coil dimensions against handling and pay-off equipment.
Surface: inspect for seams, laps, rust and heavy scale; check decarburisation against the agreed acceptance limits.
Process suitability: verify agreed mechanical results and trial drawing, forming and heat treatment before releasing the lot.

What goes wrong
A supplier may offer finished drawn spring wire when the enquiry calls for hot-rolled wire rod, or substitute a commercially similar grade with different chemistry. Both can change the classification basis. Budgeting only for the ordinary duty also misses anti-dumping. Check the mill identity, material records and declaration basis before shipment.
Surface seams can open during drawing, while decarburisation can affect finished spring performance. Tangled or distorted coils can interrupt feeding. Keep heat traceability through storage and processing, agree a trial and acceptance criteria before shipment, and use factory verification to check the supplier's production capability.

Frequently asked questions
What is the UK import duty on silicon-manganese spring steel wire rod from China?
The supplied line 7227 20 00 00 lists 0% ordinary duty plus 24.00% residual anti-dumping duty. No suspension or attached import control is recorded.
Is silicon-manganese spring wire the same as wire rod?
Check the processing history. This guide covers hot-rolled rod in irregularly wound coils; finished drawn spring wire needs separate classification.
Can my supplier use a lower anti-dumping rate?
Only where the specified-exporter conditions are met. Ask your broker to verify the producer, qualifying commercial invoice and declaration; without the invoice or declaration, the residual rate applies.
What should I check before making springs from imported wire rod?
Check heat chemistry, traceability, diameter, ovality, seams and decarburisation. Trial representative material through your drawing, forming and heat treatment processes.
