Sourcing steel fire-water tanks from China
Steel fire-water storage tanks from China pay 0% UK duty across the relevant liquid-container lines. Heading 7309 covers tanks exceeding 300 litres without mechanical or thermal equipment; pressure equipment rules depend on the design pressure. Cambridge China Bridge sources steel fire-water storage tanks.
Duty on steel fire-water storage tanks
Read from the UK Trade Tariff on 25 October 2026, the relevant liquid-container lines under heading 7309 carry 0% duty for goods from China. The supplied tariff facts show no anti-dumping or countervailing duty, steel measure, suspension or attached import control on these lines. Import VAT is normally 20%.
This heading covers steel containers exceeding 300 litres without mechanical or thermal equipment. Lined and heat-insulated tanks share a code, so those table entries represent alternatives within the same tariff line. Plain liquid tanks split at 100,000 litres. Confirm the complete imported configuration using finding your commodity code, and see the wider steel storage tank guide.
Confirm with HMRC or your customs broker whether these lines fall within the UK carbon border adjustment mechanism and when any requirements apply to your planned imports. Ask the factory for emissions information when planning later imports and consult the UK carbon border adjustment guide.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Lined steel fire-water storage tanks | 7309 00 30 00 | 0% | None |
| Unlined, uninsulated fire-water tanks exceeding 100,000 litres | 7309 00 51 00 | 0% | None |
| Unlined, uninsulated fire-water tanks over 300 up to 100,000 litres | 7309 00 59 00 | 0% | None |
Specify usable fire-water capacity and connections
Have the fire-system designer agree usable water capacity, suction outlet position, refill arrangement and minimum operating water level before requesting a factory drawing. Specify steel grade, plate thickness, corrosion protection, liner material, roof, vents, overflow, drain and access arrangements. Separate the tank specification from the pump and controls.
Agree foundation loads, anchor details, site assembly responsibilities and the inspection method for joints hidden by a liner. Specify insulation and frost protection for the intended site. Ask the designer to distinguish nominal tank volume from water actually available to the fire system.
In Great Britain, the Pressure Equipment (Safety) Regulations 2016 apply to pressure equipment with maximum allowable pressure above 0.5 bar, subject to exclusions. Atmospheric storage tanks sit outside those regulations. Establish the tank's design pressure rather than assuming that a connected fire pump makes the tank a pressure vessel.
Worked duty example
Illustrative example, not a quote: Illustrative order: four unlined, uninsulated 20,000-litre steel fire-water tanks under 7309 00 59 00, invoiced at £60,000 free on board, with £8,000 of freight and insurance to the UK. The customs value is £68,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £68,000, so it is £13,600. 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
Materials: compare plate certificates and measured thickness with the approved drawing; inspect coating coverage, liner seams and gasket identification.
Connections: check suction, refill, overflow and drain positions against the drawing, including flange compatibility and access for maintenance.
Leak testing: agree a witnessed factory test for complete tanks and a site test after assembly for sectional tanks; record leaks and repairs before acceptance.
Arrival: inspect dents, damaged coatings, liner punctures and distorted flanges; reconcile panels, bolts, seals and assembly instructions with the packing list. Arrange factory verification before production.

What goes wrong
A tank can match its advertised volume yet provide less usable fire-water storage because the suction outlet or operating water level is wrong. Incorrect flange drilling, inaccessible drains and misplaced overflow connections create site rework. Resolve these details on the approved drawing.
Weld defects, damaged liners, uneven gasket compression and transport distortion can cause leakage. A factory test cannot reveal damage sustained during shipping or mistakes made during site assembly. Allocate responsibility for arrival inspection, assembly and final leak testing in the purchase specification.

Frequently asked questions
What is the UK import duty on steel fire-water tanks from China?
The relevant heading 7309 liquid-container lines carry 0% duty in the supplied tariff facts, with no anti-dumping or countervailing duty. Import VAT is normally 20%.
Which commodity code covers a lined fire-water tank?
A lined or heat-insulated steel liquid tank within this heading uses 7309 00 30 00. Confirm its capacity and complete imported configuration before declaring it.
Does a fire-water tank need pressure equipment certification?
Atmospheric tanks sit outside the pressure equipment regulations. Designs above 0.5 bar maximum allowable pressure generally fall within them, subject to exclusions; classification determines the applicable conformity route.
What should I agree before ordering a sectional fire-water tank?
Agree usable capacity, suction and refill connections, foundation loads, panel and liner specifications, assembly responsibilities and a recorded leak test after site assembly.
