Sourcing synthetic zeolite beads from China
Synthetic zeolite molecular sieve beads matching the listed aluminium sodium silicate spheres carry 6% base UK duty, with a conditional suspension to 0%. Match composition and diameter before claiming relief, and check UK REACH registration needs. Cambridge China Bridge sources synthetic zeolite molecular sieve beads.
Base duty and conditional suspension
Read from the UK Trade Tariff on 30 September 2026, heading 3824 covers chemical products and preparations not elsewhere specified or included. The relevant supplied line is 3824 99 96 65: aluminium sodium silicate spheres within the listed diameter bands. The table shows size examples within this same commodity line, rather than separate classifications.
The supplied China tariff record shows 6% base duty, a 0.00 % autonomous suspension and no anti-dumping or countervailing entry. The suspension excludes mixtures, preparations and products made up of different components containing these products. Do not assume a binder-containing bead qualifies. The record also attaches waste and seal-product import controls and export-control entries; ask your customs broker to confirm the applicable declaration requirements.
Waste shipment controls apply only to material classed as waste. Confirm the requirements with your broker before buying spent or regenerated material from China. Seal products traded into Great Britain need a seal catch certificate; ask the broker to confirm how the attached control is addressed for synthetic beads. Confirm the commodity code using composition, binder and diameter. For the wider heading, see carbon molecular sieves.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Aluminium sodium silicate spheres, diameter 1,6 mm | 3824 99 96 65 | 6% | None |
Specify the zeolite, binder and adsorption test
Specify the zeolite chemistry, exchanged cations, binder identity and proportion, bead diameter distribution, bulk density, crush strength, attrition and moisture at packing. Identify the stream being dried or separated, its contaminants and operating conditions. Agree adsorption capacity and regeneration tests under conditions relevant to your process, rather than accepting an unexplained capacity figure.
Before importing a new substance, consider whether UK REACH registration is required. Obtain the composition and substance identity from the manufacturer so that this assessment covers the actual beads. Chemical classification law establishes a duty to classify chemicals. Request the classification assessment and safety data sheet for the supplied formulation, rather than assuming every molecular sieve grade has the same hazards.
Worked duty example
Illustrative example, not a quote: Illustrative trial consignment of synthetic zeolite beads in sealed drums under 3824 99 96 65, invoiced at £2,400 free on board, with £600 of freight and insurance to the UK. The customs value is £3,000. Duty at 6% is £180. Import VAT at 20% is charged on the customs value plus duty, £3,180, so it is £636. Import taxes total £816; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £180 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Identity: compare batch analysis, zeolite chemistry and binder content with the approved sample and purchase specification.
Beads: sieve a representative sample, check broken beads and fines, and test crush strength and attrition using the agreed methods.
Performance: test moisture and adsorption capacity on the delivered batch under the agreed conditions; retain a sealed comparison sample.
Packing: inspect drum closures and moisture-barrier liners, check net weight and batch identification, and record damaged or opened packs before use.

What goes wrong
Beads exposed to moisture during packing or transport can arrive partly loaded, leaving less capacity for the buyer's process. Weak beads produce fines during handling, while an unsuitable zeolite or binder can meet a general description yet fail the intended separation. Specify acceptance tests and compare the delivered batch with a sealed approved sample.
A supplier's customs code or suspension claim may overlook bead composition or diameter. Keep the formulation, size results and batch documents together for the broker's review. Use quality inspection guidance to agree sampling and acceptance checks before dispatch.

Frequently asked questions
What is the UK import duty on synthetic zeolite beads from China?
The supplied tariff record shows 6% base duty under 3824 99 96 65, with a conditional 0.00 % suspension. Match the listed spheres and check the suspension exclusion before claiming relief.
Do binder-containing molecular sieve beads qualify for the suspension?
Do not assume they qualify. The suspension excludes mixtures, preparations and products made up of different components containing the listed product. Give your broker the full formulation.
Do I need UK REACH registration for zeolite beads?
Consider whether registration is required before importing a new substance. Assess the actual substance identity and formulation, rather than relying on the supplier's product name.
How do I check whether molecular sieve beads arrived damp?
Inspect seals and liners, then test batch moisture and adsorption capacity against the agreed specification. Keep samples sealed so storage exposure does not distort the comparison.
