Sourcing aquarium breeding caves from China

Zero duty on ceramic breeding caves

Read from the UK Trade Tariff on 1 October 2026, heading 6914 covers other ceramic articles. For ceramic aquarium breeding caves, the relevant descriptions are porcelain or china, handmade common pottery, and other ceramics. Stoneware and terracotta examples share the other-ceramics code; the table separates these buying options.

The supplied tariff facts show 0% duty on goods from China, no anti-dumping or countervailing duty and no suspensions. Confirm the commodity code using the body material, manufacturing method and aquarium use. For another aquarium product within the wider heading, see ceramic fish spawning cones.

The tariff attaches cat and dog fur and waste import controls. Cat and dog fur, including products made from it, is banned from import. Waste shipment controls apply only where the material is waste. For a China shipment, ask your customs broker to confirm the attached requirements, particularly if it includes discarded ceramic stock. The facts also list cultural-object and fur and waste export controls.

Specify the entrance and submerged finish

Specify the intended fish species, entrance profile, internal width and depth, closed or open rear, wall thickness and base shape. Approve a physical sample that allows the intended fish to enter and turn as required. Record whether the cave will sit on substrate or attach to another surface.

Agree the ceramic body, firing process, glazed or unglazed finish and any pigments or coatings. Ask for material information and arrange testing for substance release under the intended aquarium conditions. Treat aquarium-safe claims as claims to verify. Consumer products supplied in Great Britain must be safe in normal or reasonably foreseeable use.

Worked duty example

Illustrative example, not a quote: An illustrative batch of stoneware aquarium breeding caves for a specialist retailer under 6914 90 00 90, invoiced at £4,500 free on board, with £1,500 of freight and insurance to the UK. The customs value is £6,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £6,000, so it is £1,200. 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

Shape: measure the entrance and internal clearance against the approved drawing; check that firing shrinkage has not narrowed the passage.

Surface: check inside and outside for sharp edges, cracks, loose grit, flaking coatings and glaze runs; inspect the hidden rear surface.

Immersion: rinse and soak samples under the agreed aquarium conditions; check for shedding, discolouration and movement on the intended substrate.

Packing: check individual separation and cushioning, inspect samples after the agreed carton handling trial, and match carton identification to the supplied batch.

What goes wrong

A cave can match the outside dimensions while its entrance or interior is too narrow. Warped bases rock on the tank floor, rough inner seams escape visual inspection, and thin roofs crack when unpacked. Decorative coatings can shed during soaking even when the dry sample looks acceptable.

Approve the submerged sample as well as its appearance, record the entrance profile and internal dimensions, and inspect production stock before shipment. Check arrival cartons for chips and cracks before putting stock on sale. Use the quality inspection guide to agree checks with the supplier.
