01 Why Is 18650 Battery Certification So Important?

As the most popular format for portable lithium-ion cells, 18650 batteries are widely used in consumer electronics, power tools, small energy storage systems, medical devices, and more. Their safety directly affects end-product quality and consumer safety.

The core value of certification:

Legal Market Access: CE, UL, CCC, etc., are mandatory for lawful sales. Selling without certification risks seizure, removal, and fines.
Supply Chain Requirement: Brands and retailers only accept suppliers with authoritative certifications.
Brand Protection: Certifications prevent costly recalls and reputation damage caused by safety failures.

02 Global Certification Map for 18650 Batteries

Universal Safety Standard: IEC 62133-2

All 18650 battery certifications are based on IEC 62133-2, the international safety standard defining performance under overcharge, over-discharge, short circuit, temperature cycling, vibration, and impact.

Major Market Certification Overview

表格

Market	Key Certification	Standards	Product	Key Features
Global Transport	UN38.3	UN ST/SG/AC.10/11/Rev.5	Cells / Packs	Mandatory for air & sea shipment
International	CB Certification	IEC 62133-2	Cells / Packs	Multi-country mutual recognition
EU	CE	EN 62133	Battery Packs	Mandatory for Amazon EU
USA	UL	UL 1642 (Cells)UL 2054 (Packs)	Cells / Packs	Mandatory for Amazon US
Japan	PSE	JIS C 8712 / C 8714	Cells / Packs	Circular PSE mark
Korea	KC	KC 62133	Cells / Packs	Requires CB report first
China	CCC	GB 31241-2014	Battery Packs	Mandatory for domestic sales
Taiwan, China	BSMI	CNS 15364	Cells / Packs	Local issuer required
India	BIS	IS 16046	Cells / Packs	Mandatory registration

Key Certification Breakdown

CB Certification – Global “Certification Passport”Based on IEC 62133-2. One test allows conversion to multiple national certifications, saving time and cost.
EU CE Certification – Mandatory Market AccessRequired for the EU and Amazon EU. Based on EN 62133. Non-compliant products face immediate removal.
Japan PSE Certification18650 batteries require PSE certification with detailed testing requirements.
US UL Certification – Amazon Requirement

Cells: UL 1642
Battery Packs: UL 2054Includes short-circuit, abnormal charge, forced discharge, drop, temperature, and stress tests.

China CCC CertificationMandatory for domestic sales, based on GB 31241-2014, valid for 5 years.
Taiwan BSMI CertificationIssued to local companies only, based on CNS 15364, valid for 3 years.

03 Critical Mistake: UN38.3 ≠ Market Certification

Do NOT confuse UN38.3 with market access certifications.

UN38.3: Transportation safety report for shipping only.
CE / UL / CB / PSE / KC / CCC / BSMI: Product safety certifications required for sales.

Both are mandatory and non‑interchangeable.

04 Efficient Certification Process

Planning & DocumentationDefine target markets, select an accredited lab (CNAS, CMA, CBTL), prepare specifications, schematics, BOM, labels, and manuals.
Sample Testing

UN38.3: ~2–3 weeks
IEC 62133 / CB: ~4–6 weeks
UL / CCC: ~2–4 months (including factory audit)

Report & Certification MaintenanceCertificates require annual supervision and have fixed validity periods.
