Sourcing vacuum storage bags from China

Duty and classification for household storage bags

Read from the UK Trade Tariff on 28 October 2026, heading 3924 covers plastic tableware, kitchenware, other household articles and hygienic or toilet articles. This guide covers vacuum bags for storing clothing and bedding, proposed for 3924 90 00 90. The table shows product variants sharing this proposed code. For wider heading context, see the garment storage covers guide.

The supplied facts show 6% duty for goods from China under this line, with no anti-dumping duty, countervailing duty, suspension or import control listed. These findings concern the proposed household-articles line and depend on classification of the actual bag.

Give your customs broker the film composition, construction, closure, intended use and details of any bundled pump to confirm the commodity code. Describe reusable household storage separately from bags intended to package goods for sale or transport.

Specify the film, valve and air-retention test

Specify the film layers and materials, thickness tolerance, usable dimensions, gussets, closure profile, slider, valve and cap. For hanging bags, define the hanger arrangement and seal around it. Agree the vacuum-cleaner nozzle fit or hand-pump connection. Approve a physical sample and require approval before changes to the film, valve or sealing process.

Agree a repeatable air-retention test using representative clothing or bedding. Record the filling method, closure procedure, evacuation method, storage conditions, test duration and acceptable reinflation. Repeat after opening and resealing. For roll-up bags, check the air outlet and the effort needed to expel air. Tie compression claims to the agreed contents and method.

Assess suffocation risks from the bag and risks from detachable caps or sliders; agree suitable warnings and instructions. REACH restrictions can limit, ban or set conditions on substances. Ask a laboratory to screen the film, printing and fittings for applicable restrictions through testing and certification.

Worked duty example

Illustrative example, not a quote: Illustrative order: 2,000 flat valve vacuum storage bags for clothing, subject to classification under 3924 90 00 90, invoiced at £7,000 free on board, with £600 of freight and insurance to the UK. The customs value is £7,600. Duty at 6% is £456. Import VAT at 20% is charged on the customs value plus duty, £8,056, so it is £1,611.20. Import taxes total £2,067.20; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £456 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Film and welds: compare material records and dimensions with the approved specification; inspect folds, corners and valve welds for pinholes, thinning, delamination and splits.

Closure and valve: check closure engagement across the opening, slider retention, cap fit and nozzle compatibility; inspect the valve seal for distortion or trapped debris.

Air retention: load production samples with the agreed contents, evacuate and record reinflation over the agreed duration; repeat after resealing and handling the filled bag.

Instructions and packing: check filling, closing and evacuation diagrams, warnings, product references and batch identification; inspect for packing damage to valves and closures. Plan arrival checks with the quality inspection guide.

What goes wrong

A bag can compress immediately yet slowly refill through an incompletely closed seal, distorted valve or damaged weld. Testing only empty bags can miss strain around bulky contents. Fold damage and trapped fibres can also undermine the seal. Keep leaking samples with their batch references and compare them with unopened stock.

A compatible-looking valve may not seal against the buyer's nozzle, while hanging fittings can distort the surrounding film under load. Separate affected stock and investigate before sale. Importers remain responsible for product safety after the product is placed on the market, so keep complaints linked to batches and investigate recurring safety concerns.
