Sourcing A2 tool steel bars from China

A2 bar duty depends on its processing condition

Read from the UK Trade Tariff on 1 October 2026, heading 7228 covers other alloy steel bars and rods, sections and hollow drill bars. For A2 tool steel bars from China, the selected hot-rolled, forged and other tool-steel lines show 0%; the cold-formed or cold-finished tool-steel line shows 50%. The selected lines list no suspensions or attached import controls.

The hot-rolled tool-steel line records a residual anti-dumping rate of 22.50%. The reference guide explains that this measure applies to high-fatigue-performance concrete reinforcing bar, with other bars declared using additional code 8W01 and paying no anti-dumping duty. It also explains zero-duty quota availability for cold-finished tool steel. Ask your broker to confirm the exemption and any quota claim before shipment.

Confirm the commodity code using the chemistry and actual processing route, rather than the supplier's A2 label alone. Ask your customs broker whether the selected lines fall within the UK carbon border adjustment mechanism and when any obligations apply; request mill emissions data for future imports if relevant. For the wider heading, see the D2 tool steel bars guide.

Specify A2 chemistry, condition and machining allowance

Write A2 into the purchase specification with the agreed grade standard and chemical composition. Ask the mill to identify the standard behind any proposed equivalent and obtain your toolmaker's approval before accepting a substitution. Specify round or flat section, dimensions, straightness, delivery condition and whether surfaces are black, peeled or ground.

For annealed stock, agree the delivery hardness, machining allowance and acceptable surface decarburisation. For stock supplied after heat treatment, agree hardness and distortion checks. Request a mill inspection certificate with heat number, chemistry, condition and test results, and agree ultrasonic testing where internal soundness matters. Use factory verification to check the mill's production and testing capability.

Worked duty example

Illustrative example, not a quote: Illustrative stockholder order of forged A2 tool steel bars in assorted sizes under 7228 40 10 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

Heat identity: match bar markings and bundle tags to the mill certificate, and keep different heats identifiable after cutting.

Chemistry and condition: independently sample each heat for chemistry and hardness against the agreed A2 specification; review the recorded heat treatment condition.

Dimensions and surfaces: check section size, ovality where relevant, straightness and machining allowance; inspect for rust, seams, cracks and evidence of surface decarburisation.

Packing: check moisture protection, secure restraint and readable heat tags. For wood packaging, check for a legible ISPM15 mark, which government guidance says meets the standard. Plan checks using the quality inspection guide.

What goes wrong

An A2 description on an invoice does not establish the agreed chemistry or delivery condition. Mixed heats, missing certificates and unapproved substitute grades leave the toolmaker unable to predict hardening response. Surface decarburisation or internal defects may become apparent only after machining and heat treatment. Keep a retained sample and release stock against the agreed inspection results.

A quote can also describe cold-finished material while assuming a hot-rolled tariff line. That changes the duty position. Have the broker review the processing description and certificate before dispatch, and check the rebar exemption or quota position where relevant. Budget import VAT at 20% and use UK import duty and VAT for the calculation method.
