0% duty
Read from the UK Trade Tariff on 17 November 2026, heading 4406 covers railway or tramway sleepers (cross-ties) of wood, split into not impregnated and other, and coniferous or non-coniferous. All four lines carried 0% on goods from China, with no anti-dumping measure.
Sleepers are listed in the UK Timber Regulations, so the business that first places them on the GB market must carry out due diligence on the species and country of harvest. The lines also carry a CITES import control, relevant to listed hardwood species: declare when the goods are outside its scope; otherwise obtain the required CITES import documentation and corresponding exporting-country documentation before shipment. Sawn timber is covered in other guides; confirm the commodity code.
Plant health rules apply as well. Wood of conifers and of certain hardwood genera from China is listed in Annex VII to the retained Regulation (EU) 2019/2072 with conditions such as heat treatment, kiln drying or debarking that must be certified on a phytosanitary certificate. For regulated wood, the importer must register with the Forestry Commission, submit a notice of landing before arrival and present the original certificate within 3 days; check the species with the Forestry Commission before ordering.

Specifying sleepers
Specify species, dimensions and tolerances, grade, whether new or reclaimed, any preservative treatment and the product used, moisture, and bundling. Treated sleepers for landscaping should use a treatment suitable for that use, so ask the supplier which preservative was applied and for its documentation.
Worked duty example
Illustrative example, not a quote: 500 hardwood landscaping sleepers under 4406 12 00 00, invoiced at £12,000 free on board, with £3,000 of freight and insurance to the UK. The customs value is £15,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £15,000, so it is £3,000. 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.

What goes wrong
Sleeper orders fail on species, splits and documents. A different species is supplied, sleepers split while drying, treatment records are missing, and due diligence evidence is not available.
