Sourcing ceramic fermentation crocks from China
Ceramic fermentation crocks from China carry ordinary UK duty of 4% to 8% under heading 6912, with residual anti-dumping duty of 36.10% on the listed kitchenware lines. Confirm the applicable lead and cadmium compliance evidence and written declaration of compliance requirements for food-contact ceramics with the relevant authority.

Duty on ceramic fermentation crocks
Read from the UK Trade Tariff on 29 September 2026, heading 6912 covers ceramic tableware, kitchenware, other household articles and toilet articles other than porcelain or china. For fermentation crocks, the table selects kitchenware lines by ceramic body and manufacturing method. Ordinary duty is 4% for common pottery and stoneware, 8% for earthenware or fine pottery, and 6% for other ceramics. See the wider ceramic bakeware guide.
The selected lines show residual anti-dumping duty of 36.10%, no countervailing duty and no suspensions. Check the exporter's applicable company rate before ordering. The tariff also attaches import waste control, export waste control and a cultural-object export licence measure. Waste shipment controls apply only to waste. For goods shipped from China as waste, confirm the applicable import requirements with your customs broker; also confirm the export measures if you later export the goods.
Confirm the ceramic body, intended kitchen use and whether common pottery is hand-made before selecting the commodity code. Ask the broker to check the complete crock set, including its lid and weights, against the declaration description.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Hand-made common-pottery fermentation crocks | 6912 00 21 11 | 4% | 36.10% residual anti-dumping |
| Other common-pottery fermentation crocks | 6912 00 21 91 | 4% | 36.10% residual anti-dumping |
| Stoneware fermentation crocks | 6912 00 23 10 | 4% | 36.10% residual anti-dumping |
| Earthenware or fine-pottery fermentation crocks | 6912 00 25 10 | 8% | 36.10% residual anti-dumping |
| Fermentation crocks of other non-porcelain ceramics | 6912 00 29 10 | 6% | 36.10% residual anti-dumping |
Specify the crock, water seal and food-contact surfaces
Specify the ceramic body, usable capacity with weights fitted, mouth opening, lid seating, handles and packed weight. For a water-sealed design, agree the channel profile, filling instructions and lid clearance. Specify whether weights are supplied, how they pass through the opening and how the buyer can remove them for cleaning.
Confirm with the relevant authority which lead and cadmium migration limits, written declaration of compliance and supporting test documentation requirements apply to the ceramic food-contact products. Agree testing for the actual crock glaze and food-contact weights, with acidic brine and prolonged contact described to the laboratory. Match the supplied finish to the tested sample; a general claim that the glaze is food safe is insufficient purchasing evidence.
Worked duty example
Illustrative example, not a quote: 600 stoneware fermentation crocks with lids and weights, illustrative only under 6912 00 23 10, invoiced at £7,000 free on board, with £600 of freight and insurance to the UK. The customs value is £7,600. Duty at 4% is £304. Import VAT at 20% is charged on the customs value plus duty, £7,904, so it is £1,580.80. Import taxes total £1,884.80; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £304 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Glaze: inspect the inside, rim and weights for cracks, crazing, pinholes, sharp edges and exposed areas that differ from the approved sample.
Fit and function: fit each sampled lid, fill the water channel and check for leakage. Confirm the weights enter, sit as intended and can be removed.
Capacity and stability: measure usable capacity with the supplied weights fitted, check the base sits flat and compare handles with the approved sample.
Documents and packing: match the declaration and test documentation to the supplied articles. Check that lids and weights cannot strike the crock during transport, and inspect arrival packs for concealed breakage.
What goes wrong
A warped lid can leave an uneven water seal, a cracked channel can leak, and poorly sized weights can jam in the mouth. Glaze crazing or an unapproved finish can undermine acceptance even when the colour looks correct. Approve the assembled set and its cleaning method before production.
Loose weights can break the crock from inside its own carton. Agree separate protection for moving ceramic parts and record arrival damage against the packing design. Use the quality inspection guide to agree checks before shipment.

Frequently asked questions
What is the UK import duty on ceramic fermentation crocks from China?
Ordinary duty is 4% to 8% on the selected kitchenware lines, depending on ceramic body. They also show residual anti-dumping duty of 36.10%; check the exporter's applicable company rate.
What food-contact documents should I ask for?
Ask for the written declaration of compliance and supporting lead and cadmium test documentation for the supplied crock and food-contact ceramic weights.
How do I check a water-sealed fermentation crock?
Fit the lid, fill the channel and check for leakage and uneven clearance. Confirm the weights fit through the mouth and can be removed for cleaning.
Does a crock's stated capacity include the weights?
Do not assume it does. Specify usable capacity with the weights fitted and enough space for the intended contents, then measure the assembled sample.
