Sourcing vacuum insulated food jars from China

Duty on vacuum insulated food jars

Heading 9617 covers complete vacuum flasks and other vacuum vessels, plus parts other than glass inners. Vacuum insulated food jars belong within this product family. A single-walled food container is not a vacuum vessel. See the wider vacuum vessel guide for bottles and tumblers.

Read from the UK Trade Tariff on 30 September 2026, code 9617 00 00 00 carries 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing measures, suspensions or attached import controls. Only this commodity line is supplied, so the table contains a single relevant row.

Confirm the construction and commodity code before ordering. The worked order is illustrative and uses whole-pound FOB and freight values; it is not a supplier quotation.

Specify the mouth, lid and food contact surfaces

Specify usable capacity, mouth opening, inner steel grade, lid plastics, seal material and whether the gasket can be removed for cleaning. Agree the spoon arrangement, if supplied, and check that it does not obstruct the lid or scratch the inner wall.

Food contact materials must be safe for their intended use. Ask for migration test reports for the finished jar's food contact surfaces, including the lid and seals. Describe the intended foods, filling temperature and contact duration so the laboratory can assess the proposed use.

Agree the heat retention test method, starting temperature, fill level and ambient conditions behind packaging claims. Record how the vacuum is sealed at the base and what materials are used. Approve cleaning instructions against sample trials.

Worked duty example

Illustrative example, not a quote: Illustrative order of 2,500 vacuum insulated food jars under 9617 00 00 00, invoiced at £32,000 free on board, with £2,500 of freight and insurance to the UK. The customs value is £34,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £34,500, so it is £6,900. 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

Vacuum and retention: repeat the agreed heat retention test on production samples and check the outer wall for hot spots.

Lid and gasket: leak-test filled jars upside down and on their side; check thread engagement, gasket seating and removal for cleaning.

Food contact surfaces: compare material records with the approved specification; inspect the inner weld, rim and base cover for roughness, residue or exposed sealing material.

Cleaning and packing: remove and refit the gasket, inspect food-trapping recesses and check decoration, accessories and care instructions against the approved sample.

What goes wrong

A failed vacuum lets the outside become hot and undermines the retention claim. Wide lids can cross-thread, and a displaced gasket can leak even when the lid feels tight. Food residue can remain beneath seals or around lid inserts that are difficult to remove.

Investigate these faults before accepting the batch. Repeat leakage tests after removing and refitting the seal, compare retention results with the agreed method and inspect coating damage after cleaning trials. Use quality inspection to record findings against the approved specification.
