Scope of subheading 850640

Subheading 850640 covers primary cells and batteries with silver oxide (Ag2O). Silver oxide batteries are miniature coin cells at 1.55 V, used in watches, calculators, hearing aids, electronic thermometers and car keys. Formats: SR44, SR626, SR721, SR920. Silver oxide replaced mercury batteries due to similar voltage without toxicity. Classification per GRI 1 and 6.

Regulatory requirements

Subject to Battery Regulation (EU) 2023/1542: labelling, mercury/cadmium limits, recycling. Button cells pose child swallowing hazard - child-resistant packaging required by Regulation (EU) 2023/988 and IEC 60086-4. RoHS 2 applies. CE marking required. CBAM does not apply.

Customs duties and trade

MFN rates should be verified in TARIC. Imported mainly from Japan (Renata/Swatch, Maxell, Murata), China and Switzerland. Stable market for watches and medical devices. Preferential rates under FTAs require rules of origin. VAT charged on import.

EU Battery Regulation and batteries under 8506 40

Primary batteries under CN 8506 40 are subject to the EU Battery Regulation (EU) 2023/1542. From 18 February 2027, portable batteries must meet requirements for minimum recycled content, labelling and a battery passport. Mercury oxide batteries are banned in the EU. MFN duty: 4.7%. Import requires registration in the national battery producer registry. WEEE obligations also apply.

Frequently asked questions

Do silver oxide button cells require child-resistant packaging?
Yes. Button cells (including silver oxide) pose swallowing hazards. Battery Regulation (EU) 2023/1542 requires child-resistant packaging. IEC 60086-4 defines technical requirements. Fully effective from 2025. Importer must ensure packaging compliance.
Which silver oxide battery formats are most commonly imported?
Most common: SR626SW (watches), SR44 (calculators, cameras), SR721SW, SR920SW, SR621SW. SR designations indicate silver oxide; LR designates alkaline. Formats defined by IEC 60086.
Are silver oxide batteries subject to CBAM?
No. CBAM covers: steel, aluminium, cement, fertilisers, electricity and hydrogen. Batteries from Chapter 85 are not within CBAM scope.
What Battery Regulation requirements apply to 8506 40?
Batteries under 8506 40 are subject to (EU) 2023/1542: labelling, minimum recycled content from 2027, producer registration, and battery passport. Mercury batteries are banned.
