Sourcing zinc rainwater gutters from China

Zero duty on other articles of zinc

Read from the UK Trade Tariff on 9 November 2026, heading 7907 covers other articles of zinc. The relevant line for formed zinc gutters is 7907 00 00 90, carrying 0% duty for goods from China. The supplied tariff facts list no anti-dumping or countervailing duty and no suspension. The table shows gutter configurations sharing this line, rather than separate tariff subdivisions.

The UK Trade Tariff attaches import and export waste controls to this line. Waste shipment controls apply only where the material is waste. For scrap, discarded gutters or uncertain consignments from China, confirm the applicable import requirement with your customs broker before shipment. The export control entry should also be checked if planning a subsequent waste export.

Confirm the commodity code using the material, finished profile and function of each component. Galvanised steel is steel, and unformed zinc sheet belongs to a separate heading. Mixed-material accessories need their own classification check. See the wider zinc articles guide for other products within this heading.

Gutter profiles, joints and installation details

Specify the zinc composition, sheet thickness, developed profile, finished length, edge bead and surface finish on approved drawings. Include corners, stop ends, outlets, joint overlaps and bracket interfaces. Ask the installer to agree the jointing method, thermal movement arrangement and suitability for adjoining roof materials. Approve an assembled sample with the intended fittings before bulk production.

For construction products, CE marking continues to be available for the Great Britain market. Before requesting marks, have a compliance adviser check the exact gutter system and intended use against the relevant construction-product route. Ask which standard or technical assessment, declaration of performance and supporting tests apply, if any. Use testing and certification support to review the proposed evidence.

Worked duty example

Illustrative example, not a quote: Illustrative order: 2 tonnes of formed zinc rainwater gutters 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 batch composition records with the agreed zinc specification and measure sheet thickness on sampled gutters and fittings.

Shape: check profile, straightness, edge bead and outlet position against the drawings; trial-fit gutters in the intended brackets.

Joints: assemble corners, outlets and stop ends using the agreed jointing method, then run a water test and inspect seams for leakage.

Arrival: inspect bundles for crushed profiles, wet wrapping, scratches and missing fittings; compare surface appearance with the approved sample and retain batch identification.

What goes wrong

A gutter profile can look correct yet fail to fit the installer's brackets. Poorly matched corners and outlets leave gaps, while inconsistent edge beads make joints difficult to assemble. Thin material and unsupported bundles can arrive distorted. Specify acceptance points on the drawing and test the complete assembly rather than approving loose straight lengths alone.

Wet packaging can leave uneven surface marks, and poorly protected nesting can scratch visible faces. Ask the factory to demonstrate bundle support, separation and moisture protection. Quarantine damaged or mismatched stock on arrival and record the affected batches before agreeing replacement parts.
