Sourcing ceramic chimney liners from China

Duty on ceramic chimney liners

Read from the UK Trade Tariff on 4 November 2026, heading 6905 covers ceramic roofing tiles, chimney pots, cowls, chimney liners and other ceramic constructional goods. Ceramic chimney liners fall within the Other line, 6905 90 00 00. The table shows buying formats sharing that tariff line, rather than separate commodity lines.

The recorded duty for goods from China is 0%, with no anti-dumping or countervailing measure and no suspension listed. The tariff attaches import waste control, alongside cultural-object and waste export controls. Waste shipment controls apply only where the material is waste. For any waste shipment from China, confirm the applicable requirement with your customs broker before dispatch.

Confirm the material and intended use through finding your commodity code. For the wider heading, see ceramic chimney pots. Import VAT is normally 20%; see UK import duty and VAT.

Specify the liner and its chimney system

Specify the internal profile, clear bore, section length, wall thickness, dimensional tolerances and joint geometry. State the intended fuel, appliance, operating conditions and whether the liner forms part of a complete chimney system. Include matching bends, access sections and the proposed jointing material in the specification.

Ask for a declaration of performance and supporting reports matching the exact liner model and intended use. Check the claimed temperature, condensate resistance, gas tightness and soot-fire performance against the project specification. Where CE marking has been legitimately affixed, the product can continue to be supplied in Great Britain without additional UK marking.

Worked duty example

Illustrative example, not a quote: Illustrative palletised order of ceramic chimney liner sections for a building merchant under 6905 90 00 00, invoiced at £14,000 free on board, with £4,500 of freight and insurance to the UK. The customs value is £18,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £18,500, so it is £3,700. 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 the bore, wall thickness, straightness and joint ends against the approved drawing; dry-fit sections to check alignment and seating.

Ceramic body: inspect inner and outer surfaces for cracks, chipped joint edges, distortion and loose material, including sections from different pallets.

Evidence: match product identification, batch details and claimed performance to the supplied documents; investigate reports describing a different liner or system.

Packing: check cushioning, separation and restraint around joint ends; photograph damage on arrival before unpacking further. See quality inspection.

What goes wrong

Distorted sections leave uneven joints or reduce the clear bore. Chipped ends prevent consistent seating, while cracks can remain hidden beneath packing. A liner selected only by diameter may have performance claims that do not match the intended fuel or operating conditions.

Approve a sample assembly with the proposed jointing material before ordering. Agree acceptance criteria for cracks, joint damage and dimensions, and retain batch-linked evidence. Ask the project designer or installer to confirm system compatibility before accepting substitutions.
