Sourcing fibre-cement ridge caps from China
Fibre-cement ridge caps from China fall within heading 6811, whose recorded duty rates are all 0%, with no trade remedies. Caps with intentionally added asbestos cannot be imported into Great Britain. Specify asbestos-free material and check the roof profile and performance documents. Cambridge China Bridge sources fibre-cement ridge caps.
Ridge-cap duty and the asbestos restriction
Heading 6811 covers articles of asbestos-cement, cellulose fibre-cement or similar materials. For asbestos-free ridge caps, compare the other-articles line with the sheets, panels, tiles and similar-articles line using the actual material and shape. The table also includes adjoining roof-sheet goods and the asbestos line for context. See the wider fibre-cement roof sheets guide.
Read from the UK Trade Tariff on 1 October 2026, all recorded lines carry 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duties, suspensions or attached import controls. This does not override the asbestos restriction: new ridge caps with intentionally added asbestos cannot be imported into Great Britain.
Give your customs broker the composition, cross-section drawing, photographs and intended use before agreeing the code. Do not assume that a separate ridge fitting takes the same code as the roof sheet. Use finding your commodity code to prepare the classification enquiry.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Other asbestos-free fibre-cement articles, a candidate line for ridge caps | 6811 89 00 00 | 0% | None |
| Other asbestos-free sheets, panels, tiles and similar articles | 6811 82 00 00 | 0% | None |
| Asbestos-free corrugated sheets, for comparison with the adjoining roof | 6811 81 00 00 | 0% | None |
| Asbestos-containing articles; new caps with intentionally added asbestos are banned | 6811 40 00 00 | 0% | None |
Specify the ridge angle and roof-sheet fit
Specify asbestos-free fibre-cement, the roof pitch, cap angle or adjustment arrangement, wing width, overall length, effective cover after overlap, thickness and fixing positions. Identify the exact roof-sheet profile and agree whether the cap is plain, profiled or ventilated. Approve a sample assembly with the intended sheets, fixings, washers and closures before production.
Confirm whether the cap is covered by a designated construction-product standard or a technical assessment. Products within that scope need conformity assessment, performance documentation and conformity marking. UKCA and compliant CE marking are accepted for Great Britain. Ask for documents identifying the actual cap model and intended use, together with the supporting strength, durability and weather-resistance results. Arrange testing and certification around the agreed product.
Worked duty example
Illustrative example, not a quote: Illustrative palletised stock order of asbestos-free ridge caps for a roofing merchant under 6811 89 00 00, invoiced at £9,000 free on board, with £2,500 of freight and insurance to the UK. The customs value is £11,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £11,500, so it is £2,300. 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: check the asbestos-free specification, supplier material declaration and laboratory report against the supplied batch and cap model.
Fit: measure the angle, wing width, length, thickness and fixing positions against the approved drawing. Dry-fit samples to the intended roof-sheet profile and check overlap seating.
Condition: inspect the crown, wings, overlap ends and fixing holes for cracks, chips and distortion. Compare colour and coating with the approved sample.
Packing and records: check separation between caps, support beneath nested pieces and protection from strapping pressure. Match batch labels and performance documents to the delivery. Use the quality inspection guide to agree the inspection brief.

What goes wrong
A cap can have the right overall width but the wrong angle or underside profile, leaving gaps where it meets the sheets. Incorrect overlap ends prevent adjoining caps from seating. Misplaced fixing holes encourage installers to force the cap into position, which can crack the wings or crown.
Nested caps can rub through coatings or break under strapping and transport loads. Reports for a roof sheet or a different fitting do not establish the ordered cap's performance. Record arrival damage before installation, separate suspect pieces and compare the delivered batch with the approved assembly and documents.

Frequently asked questions
What is the UK import duty on fibre-cement ridge caps from China?
The supplied tariff record shows 0% across heading 6811, with no anti-dumping or countervailing duties. Confirm the ridge cap's exact commodity code from its composition and shape.
Can I import asbestos-cement ridge caps from China?
New caps with intentionally added asbestos cannot be imported into Great Britain. A tariff code and a duty rate do not override the prohibition. Specify asbestos-free material and obtain testing.
Do fibre-cement ridge caps need CE or UKCA marking?
Where a designated construction-product standard or technical assessment applies, conformity marking and performance documentation are required. UKCA or compliant CE marking is accepted in Great Britain.
Will Chinese ridge caps fit my existing roof sheets?
Check the actual sheet profile, roof pitch, cap angle, overlap and fixing arrangement. Approve a dry-fitted sample assembly rather than relying on a catalogue photograph.
