Zero duty

Read from the UK Trade Tariff on 25 September 2026, cast fittings of non-malleable cast iron, malleable and ductile iron fittings, flanges, threaded sleeves, elbows and bends, and butt-welding fittings of iron or steel carried 0% duty on goods from China, with no anti-dumping measure on the lines checked.

Fittings are dense, so the container weight limit sets the freight share of the landed price. Confirm the commodity code by material and fitting type.

Standards, threads and pressure

Fittings are specified by standard: the thread form, British Standard Pipe or another, the flange standard and pressure class, and the pressure and temperature rating. Put the standard, size range, material grade and finish, black, galvanised or coated, in the product specification, and ask for material certificates with each batch.

Check threads with gauges and dimensions on samples at inspection, and ask for a pressure test on a sample from each batch for pressure-rated fittings.

Drinking water and gas

Fittings on water supplied by a water undertaker are water fittings: regulation 4 of the Water Supply (Water Fittings) Regulations 1999 requires them to be of an appropriate quality and standard, shown by a British Standard or a regulator-approved specification, and merchants often ask for third-party approval. The taps and valves guide covers the rule.

Fittings for gas, fire protection or pressure systems have their own standards and approvals; state the application so the factory supplies the right product and evidence.

Galvanising and corrosion

Hot-dip galvanised fittings are specified by coating thickness; check it on samples, along with thread damage from the galvanising. Oil and cap the threads for the sea voyage.
