Duty and the waste-control entry
Read from the UK Trade Tariff on 4 October 2026, heading 7907 covers other articles of zinc. Formed zinc chimney flashings are candidates for 7907 00 00 90, whose duty on goods from China is 0%. The supplied tariff record lists no anti-dumping or countervailing measure and no suspension. The table shows different flashing forms using the same tariff line.
The UK Trade Tariff attaches import and export waste controls to this line. For material from China treated as waste, ask your customs broker to confirm the applicable import procedure before shipment. Waste shipped under notification controls requires consent from the destination, dispatch and transit competent authorities. Do not treat the tariff entry as a waste permit for finished flashings.
Confirm the commodity code using drawings, material composition and the condition of the imported goods. Zinc sheet and strip belong to a separate heading, and galvanised steel is steel. See the formed zinc roof valleys guide for the wider product family.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |

| Formed zinc chimney apron flashings | 7907 00 00 90 | 0% | None |
Chimney dimensions, roof pitch and corner details
Specify solid zinc or the agreed zinc alloy, sheet thickness, finish and dimensional tolerances. Supply a drawing showing chimney dimensions, roof pitch, apron projection, side upstands, back-gutter shape and the edge entering the masonry joint. Identify handed parts and show how adjoining pieces overlap. Agree corner construction, seam treatment and compatibility with the intended jointing method.
Approve a trial assembly against a chimney and roof mock-up before bulk production. Ask a testing and certification adviser to establish which construction-product standard or assessment, marking and performance documents apply to the actual product. For Great Britain, legitimately CE-marked construction products can continue to be supplied without an additional UK mark.
Worked duty example
Illustrative example, not a quote: Illustrative order: 2 tonnes of formed zinc chimney flashings for roofing stock under 7907 00 00 90, invoiced at £9,000 free on board, with £900 of freight and insurance to the UK. The customs value is £9,900. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £9,900, so it is £1,980. 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
Material: compare the batch material certificate, thickness and finish with the approved specification; inspect for substitution with galvanised steel.
Fit: check roof angle, upstands, apron projection and handedness against the drawing; trial-fit adjoining pieces.
Seams: inspect folded corners and any soldered joints for cracks, open gaps and pinholes; check drainage on the agreed mock-up.
Packing: check separators, corner protection and part identification; inspect unpacked pieces for crushed folds, scratches and trapped moisture.

What goes wrong
A flashing can match the chimney width yet fail to fit because the roof angle or upstand detail is wrong. Reversed side pieces, shortened overlaps and distorted back gutters leave awkward joints for the roofer. Agree the assembly drawing and approve a fitted sample rather than accepting separate photographs of loose parts.
Tight bends can crack, corner seams can leak and nested pieces can arrive with flattened folds. Compare arrival samples with the approved assembly, record damage before distribution and separate affected stock. Keep material identity and surface finish consistent across adjoining pieces.
