Sourcing D2 tool steel bars from China

Duty depends on the working of the bar

Read from the UK Trade Tariff on 24 October 2026, heading 7228 covers other alloy steel bars and rods, sections and hollow drill bars. For D2 bars, the relevant tool steel lines distinguish hot-rolled, forged, cold-finished and other worked bars. The table gives classification candidates, not a code established by the D2 name alone.

The supplied tariff lists 0% for hot-rolled, forged and other worked tool steel bars, and 50% for cold-formed or cold-finished tool steel bars. Our published wider guide explains the cold-finished line's 0% quota treatment. The hot-rolled line lists 22.50 % residual anti-dumping duty; the wider guide limits this to high-fatigue-performance rebar, with other bars declared using additional code 8W01. These selected lines list no suspensions, countervailing duties or attached import controls.

Include the commodity code on the import declaration. Give your broker the chemistry, cross-section and complete processing route, then confirm the commodity code. Check quota treatment before shipping cold-finished bars. See the wider alloy steel bars guide for heading-wide measures and the forthcoming carbon border adjustment mechanism.

Specify D2 grade and delivery condition

Specify D2 against an agreed tool steel specification and chemical composition, rather than accepting an undocumented equivalent. State whether bars are supplied annealed or hardened, the agreed hardness range, round or flat section, dimensions, straightness, surface finish and machining allowance. Record whether the mill rolls or forges the stock and which finishing operations follow.

Ask for a heat-specific inspection certificate showing chemistry, heat number and delivery condition. Agree independent chemistry and hardness checks, and any ultrasonic inspection needed for your tooling. For bars intended for machining and later hardening, agree a sample machining and heat-treatment trial before accepting the production material.

Worked duty example

Illustrative example, not a quote: Illustrative order: 20 tonnes of forged D2 tool steel bars under 7228 40 10 00, invoiced at £42,000 free on board, with £2,000 of freight and insurance to the UK. The customs value is £44,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £44,000, so it is £8,800. 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

Traceability: match bar and bundle heat markings to the inspection certificate, packing list and purchase specification.

Material: compare certified chemistry with the agreed D2 specification and check sample hardness against the ordered delivery condition.

Dimensions: measure diameter or flat section, length, straightness and machining allowance against the drawing.

Surface and packing: check for cracks, decarburisation, rust, damaged ends and moisture beneath wrapping; record defects before releasing stock.

What goes wrong

An equivalent grade is supplied without an agreed chemistry comparison, or annealed and hardened stock become mixed. Variable hardness can disrupt machining; surface decarburisation and internal defects can emerge during toolmaking. Keep suspect heats separate and resolve discrepancies against the purchase specification.

A quotation describes bars as forged even though later cold finishing changes the classification. Another failure is treating the hot-rolled line's anti-dumping entry as a charge on every D2 bar. Have the broker check the actual working route and declaration treatment before dispatch.
