As mainstream portable energy storage accessories for consumer electronics, power banks are widely used in daily life. Frequent safety incidents caused by uneven product quality have driven the official release of GB 47372-2026 Safety Technical Specification for Power Banks, which will reshape the whole industry regulation pattern.

Different from the former recommended standard GB/T 35590-2017, GB 47372-2026 is a national mandatory standard. In accordance with Standardization Law of the People’s Republic of China and Compulsory Product Certification Administration Rules, all power banks manufactured, sold, imported or circulated in China must obtain CCC certification and affix CCC marks starting from April 1, 2027. Non-certified products are prohibited from production and commercial sales.

This policy upgrade fully transforms power bank industry from voluntary certification to mandatory certification, greatly raising market access thresholds. Manufacturers and brand owners shall get familiar with new standard requirements and arrange certification schedules in advance.

1. Five Core Major Revisions of GB 47372-2026

Compared with GB/T 35590-2017, the new standard carries comprehensive upgrades on technical specifications and quality supervision mechanisms:

1. New Nail Penetration TestOne of the most highlighted updates. This internal short-circuit test simulates actual thermal runaway risks by penetrating battery cells with steel nails, filling the critical safety verification gap in the old standard.

2. Lithium Precipitation Detection after Cycle AgingThe new standard adds lithium precipitation morphology inspection after repeated charge-discharge cycles, evaluating safety margin degradation during long-term service.

3. Clear Requirements for Intelligent Management SystemFormalized performance indicators for BMS functions including overcharge protection, overdischarge protection, overcurrent protection, short circuit protection and temperature monitoring to ensure reliable battery management performance.

4. Unique Traceable Coding MandateAll power banks shall be marked with exclusive identifiable codes to realize full-lifecycle product traceability, matching national electronic product supervision policies and facilitating official market inspection.

5. Full-process Quality Control RegulationApart from type testing, the standard sets strict requirements on enterprise quality management systems, covering key component supplier management, in-process production control and factory outgoing inspection to build complete safety control chains from R&D to delivery.

2. CCC Certification Application Procedures & Key Timelines

表格

Four-step Application Process

1. Enterprise Preparation: Confirm product models and complete technical documents including circuit diagrams, BOM, structure drawings and BMS specifications.
2. Type Testing: Deliver samples to qualified authorized testing institutions for full standard compliance tests.
3. Factory Audit: Certification authorities conduct on-site inspection on manufacturer’s quality assurance capability.
4. Certificate Issuance: Official CCC certificate will be granted after passing all tests and audits, then enterprises can attach CCC marks on qualified products.

3. Core Benefits of Obtaining Power Bank CCC Certification

Despite increased compliance costs, CCC certification brings long-term competitive advantages:

• Stable Market Access: Avoid product removal, recall penalties and administrative fines after the mandatory execution date.
• Authoritative Quality Endorsement: National compulsory certification effectively verifies product safety and boosts consumer purchasing confidence.
• Optimized Supply Chain Management: Standardized supplier regulation and full-process control help enterprises build more stable and compliant supply chains.
• Promoted Brand Influence: CCC marking proves product legality and corporate social responsibility, supporting brand value upgrading and premium pricing.

4. FAQ

Q1: Main differences between GB 47372-2026 and GB/T 35590-2017?A1: GB/T 35590-2017 is a voluntary recommended standard; GB 47372-2026 is fully mandatory nationwide since April 1, 2027. Technically, the new standard adds nail penetration test, cycle aging lithium precipitation test, standardized BMS requirements and traceable coding rules with much stricter safety thresholds.

Q2: Do pre-produced inventory power banks need CCC certificates?A2: All products launched for sale after the mandatory date must hold valid CCC certificates. Different disposal policies may apply to finished stock made before the deadline, please follow official CNCA announcements. Early certification application is strongly recommended to avoid market operation risks.

Q3: How long does GB 47372-2026 testing take?A3: Standard type testing takes 4–6 weeks with one-pass samples; the whole CCC certification procedure takes 6–10 weeks in total. Unqualified test items will extend the whole cycle due to rectification and retesting.

Q4: Specific BMS requirements stipulated by GB 47372-2026?A4: The standard specifies clear threshold values and response time for overcharge, overdischarge, overcurrent, short circuit and temperature protection. BMS shall maintain stable protective performance under extreme working conditions such as low-temperature charging and over-temperature operation.

Q5: Are other certifications still required for exported power banks?A5: Yes. Additional overseas certifications are necessary for cross-border sales: CE (LVD/EMC/Battery Directive) for EU markets, UL/FCC for North America, PSE for Japan and KC for South Korea. Enterprises can arrange domestic and overseas certification projects simultaneously to cut overall compliance costs.

5. Summary & Practical Suggestions

The official implementation of GB 47372-2026 marks a brand-new mandatory supervision era for the power bank industry. This policy tightening drives overall industry safety upgrading and standardized development.

We suggest all power bank manufacturers and brand merchants take prompt actions:

1. Finish standard training and complete technical document preparation within the second half of 2026 and submit certification applications as early as possible.
2. Cooperate with CMA & CNAS accredited testing laboratories familiar with GB 47372-2026 to raise first-pass test rate.
3. Communicate with core component suppliers in advance to ensure cells and BMS modules fully meet new standard specifications.
4. Establish standardized internal quality management systems to pass official factory inspections smoothly.
