Sourcing Slate Wall Cladding from China

UK duty on slate wall cladding

Read from the UK Trade Tariff on 23 November 2026, heading 6803 covers worked slate and articles of slate or agglomerated slate. Roofing and wall slates fall under 6803 00 10 00. The table shows wall-slate variants sharing that tariff line. See the wider slate guide for other slate products.

Both tariff lines in the supplied heading carry 0% duty for goods from China. The snapshot lists no anti-dumping or countervailing duty, suspension or attached import control. Import VAT is separate from customs duty; see UK import duty and VAT.

Confirm the material and construction before ordering, particularly for bonded panels, backing materials or mixed-stone products. Give your customs broker photographs, a material breakdown and the intended use, then confirm the commodity code. A supplier's description of 'slate cladding' is insufficient to settle classification.

Specify the slate face and fixing arrangement

Specify natural slate, the quarry or material source, colour range, face finish, edge treatment, dimensions and permitted thickness variation. Agree a physical sample showing acceptable mineral inclusions and colour variation. State whether the order is loose wall slates or bonded panels, and describe any backing, adhesive or coating.

For roofing and cladding slates, confirm with the relevant authority whether BS EN 12326-1 applies and which declaration of performance and CE or UKCA marking requirements apply. Check the declared water absorption, thermal cycling and sulphur dioxide exposure classes against the intended use. CE marking continues to be recognised for construction products in Great Britain. For bonded panels, ask a compliance adviser to confirm the applicable product standard rather than accepting a loose-slate report.

Agree hole positions, edge distances and the fixing arrangement with the project designer. Ask for a trial wall layout using production samples to check joints, face variation and corner details. Record packing arrangements that support the stone and protect exposed edges.

Worked duty example

Illustrative example, not a quote: Illustrative order: 20 tonnes of natural wall slates in crates; freight includes insurance. under 6803 00 10 00, invoiced at £16,000 free on board, with £2,600 of freight and insurance to the UK. The customs value is £18,600. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £18,600, so it is £3,720. 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

Documents: match the declaration of performance, marking and test reports to the exact slate supplied and its declared classes.

Dimensions and fixing: sample across crates for length, width, thickness, flatness, edge quality and hole positions; compare with the approved drawing.

Surface and structure: compare colour with the approved sample; inspect for cracks, delamination, loose layers and metallic inclusions. For bonded panels, inspect joints and backing attachment.

Arrival condition: photograph damaged crates before unpacking, inspect corners and faces, and retain crate identification with the findings. Use a written inspection brief.

What goes wrong

Pyrite inclusions can oxidise and stain the wall. Excessive thickness variation makes joints uneven, while cracks and delamination leave weak pieces. An attractive face sample can conceal these problems, so inspect production material across crates and compare it with the declared performance.

Loose packing causes chipped edges and broken corners. Bonded panels also need checks for loose strips and mismatched corner pieces. Agree how defects will be recorded and resolved before dispatch, and keep arrival photographs linked to the affected crates.
