Import Duty on Lithium-Ion Batteries to UK

Estimate UK landed cost for lithium-ion batteries and check the relevant tariff classification and measures.

UK landed cost calculator

Build the customs value, apply a tariff rate, estimate import VAT and see the total landed cost. You can search the UK Trade Tariff or enter a known 10-digit commodity code.

1. Find the tariff classification

Start with a product description or enter the code if you already know it.
Classification matters: choose the description that actually matches the goods.
Use the customs origin of the goods, not simply the seller, warehouse or dispatch country.

2. Enter the shipment values

Enter the intrinsic/customs goods value before any separately charged UK VAT. Goods with no sale price still require an appropriate customs value.
Examples: customs clearance, handling, storage and known onward transport costs that belong in the import VAT value.
Optional business costs incurred after the import VAT valuation point. These are added to landed cost but not used to calculate import VAT.
Enter a rate manually or check the official tariff above.
20% UK standard-rate planning default. Official commodity data can automatically replace it with a clear reduced or zero rate when applicable.
Enter the customs/tariff weight when the official rate is charged per kg, 100 kg or tonne. BorderMath will use it automatically.
Low-value / VAT handling
BorderMath will choose a planning default from the shipment value; change it if your transaction differs.
Tick only when the goods are actually excise-liable. If ticked, BorderMath will withhold final VAT because Excise Duty must be included in the VAT value.
Simplified planning model for Great Britain: customs value = goods + freight + insurance. Import VAT value adds customs duty and qualifying incidental expenses up to the relevant UK destination. For qualifying low-value sales, seller/marketplace VAT paid at checkout is kept separate from customs value and added only to the cash landed-cost total. Post-import costs are added after VAT. Low-value, excise, trade-remedy and Northern Ireland rules can differ.

Identify exactly what kind of battery product is being imported

“Lithium battery” is not a complete customs description. Record whether the item is a rechargeable lithium-ion cell or battery, a battery pack, a battery incorporated into equipment, or equipment shipped with a separate battery. If the shipment is a replacement pack, describe the pack itself as well as the equipment it is designed to power.

QuestionUseful detail
Rechargeable?Distinguish rechargeable accumulators from primary cells/batteries.
Standalone or with equipment?State whether the battery is separate, packed with or contained in equipment.
Cell or assembled pack?Record the form actually imported.
OriginUse manufacturing origin, not the distributor's location.

Customs duty and dangerous-goods transport are separate checks

This page estimates UK customs duty and import VAT. It does not decide whether a lithium battery shipment complies with carrier, packaging, dangerous-goods or transport requirements. A correct tariff calculation does not make a shipment acceptable for air, sea, road or courier transport.

Worked landed-cost workflow

A battery shipment worth £2,000 with £180 freight and £20 insurance gives a simplified customs value of £2,200. The live tariff measure then determines the duty formula. If the tariff exposes additional conditions, read the official measure instead of treating the base result as the complete import requirement.

Official sources and review

Reviewed 6 September 2026. Use the UK Trade Tariff for classification and import measures and HMRC's commodity-code guidance if the battery/equipment relationship is uncertain.

Planning estimate only. Check the live official measure and supporting evidence before a customs declaration. See BorderMath methodology and limitations.
