Sourcing Slate Coping Stones from China
Slate coping stones from China carry 0% UK duty under heading 6803, with no anti-dumping or countervailing measure listed. CE marking remains accepted for construction products in Great Britain; confirm the applicable standard for the intended wall-coping use. Cambridge China Bridge sources slate coping stones.
UK duty on slate coping stones
Read from the UK Trade Tariff on 4 October 2026, heading 6803 covers worked slate and articles of slate or agglomerated slate. Slate coping stones belong within the other-articles line, 6803 00 90 00. The table shows coping profiles sharing that line, rather than separate tariff subdivisions.
Both lines in this heading carry 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing measures, suspensions or attached import controls. Solid wood packaging used to import goods into Great Britain must nevertheless meet the international phytosanitary packaging standard.
Confirm the material, processing and intended use with your broker using our commodity-code guide. For the wider slate heading, see slate window sills.

Specify the coping profile and outdoor performance
Give the factory a drawing showing the wall width, finished coping width, overhang, thickness, top profile and joint arrangement. Specify the position and continuity of underside drip grooves, including through corner and end pieces. Agree the exposed edge finish, acceptable colour variation and whether the surface is natural, honed or coated.
Ask for evidence of water absorption, frost resistance and flexural strength relevant to the stone and intended exposure. Ask your compliance adviser to identify the applicable construction-product standard and confirm the declaration of performance and marking needed for the intended use. CE marking remains accepted for construction products in Great Britain.
Approve a sample assembly showing straight lengths, a corner and an end piece. Check that grooves clear the wall faces and that adjoining profiles align. Agree crate identification, separators and support for long pieces before production.
Worked duty example
Illustrative example, not a quote: Illustrative order: 20 tonnes of crated slate coping stones for a building-materials merchant under 6803 00 90 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
Dimensions: measure sampled pieces from different crates against the drawing, including thickness, squareness, straightness and the shape of adjoining ends.
Drainage: check top profiles, overhangs and underside drip grooves against the approved assembly, including corner and end pieces.
Stone condition: inspect exposed and underside faces for cracks, splitting layers, chipped corners, mineral inclusions and colour outside the agreed sample range.
Packing and records: check supports, separators, crate identification and the agreed performance documents. Confirm solid wood packaging compliance and photograph damage on arrival. Use our inspection guide to brief the inspector.

What goes wrong
A coping can match the colour sample but miss the wall detail. Insufficient overhang or misplaced grooves can leave water running down the wall. Mismatched corner profiles interrupt the finished line, while thickness variation creates uneven joints. Check the complete assembly before approving production.
Slate can split along its layers, crack in frost or develop rust staining from oxidising mineral inclusions. Unsupported lengths and loose packing cause broken corners in transit. Agree acceptable defects and stone-performance evidence, then compare the delivered batch with the approved sample and drawing.
