Sourcing gypsum partition blocks from China

Duty on gypsum partition blocks

Read from the UK Trade Tariff on 1 October 2026, heading 6809 covers articles of plaster or of compositions based on plaster. Gypsum partition blocks should be checked against the other-articles line, 6809 90 00 00. The table shows block variants against that same tariff line, rather than separate commodity codes.

The supplied tariff record shows 0% duty for goods from China across the heading, with no anti-dumping or countervailing duty and no suspension recorded. No import control is attached to the other-articles line. The board lines have waste import and export controls; if your goods fall there, ask your customs broker to confirm the requirement.

Confirm the commodity code using the block composition, shape and intended use before shipping. For boards and decorative plaster products, see the wider plaster guide.

Block geometry and declared performance

Specify solid or hollow construction, length, height, thickness, mass, joint profile and agreed dimensional tolerances. Include drawings of tongues, grooves and hollow sections. Identify ordinary or moisture-resistant blocks, the intended partition use, compatible adhesive and required finish. Approve assembled samples so the supplier can demonstrate joint fit.

Confirm with the relevant construction products authority whether BS EN 12859 applies to the gypsum blocks and what declaration of performance and UKCA or CE marking documentation is required. CE marking continues to be available for construction products placed on the Great Britain market. Match any declaration and supporting reports to the exact block type ordered; use testing and certification to review the evidence.

Worked duty example

Illustrative example, not a quote: Illustrative order of 1,500 gypsum partition blocks under 6809 90 00 00, invoiced at £7,500 free on board, with £2,400 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

Geometry: measure sampled blocks against the agreed drawing, check squareness and flatness, and assemble adjoining pieces to assess joint fit.

Condition: inspect faces, corners and tongues for cracks, chips, loose material and damp patches; record arrival damage before moving the pallets.

Documents: match product identification on packs to the declaration of performance, marking and supporting reports; check that claimed performance belongs to the supplied block type.

Packing: check pallet support, edge protection, wrapping and load restraint; look for crushed lower layers and moisture inside the wrapping.

What goes wrong

Chipped tongues prevent tight joints, thickness variation makes wall faces uneven, and cracks can remain hidden inside wrapped pallets. Moisture-resistant blocks can also be supplied with documents for an ordinary block. Agree acceptance criteria and photograph production samples and pallet packing before dispatch.

At arrival, keep damaged or mismatched batches separate while you compare them with the approved samples and documents. A marking on the wrapper does not establish that the delivered block matches the declared performance. Arrange a quality inspection around geometry, joint fit and packing.
