At a Glance
- China has introduced a new safety standard, GB 47372-2026, specifically for power banks.
- Certification is shifting from product-only testing toward full lifecycle quality supervision.
- New abuse tests significantly raise battery safety requirements.
- Manufacturers must establish product traceability systems.
- Overseas brands should prepare for longer lead times and stricter factory audits.
Why Did China Introduce New CCC Rules?
Over the past few years, several high-profile incidents involving lithium batteries and portable power products have increased concerns about battery safety.
At the same time, power banks have evolved significantly:
- Higher charging power
- Larger battery capacities
- Laptop charging applications
- More complex battery management systems
Traditional certification frameworks were primarily designed to verify whether a finished product met minimum safety requirements.
However, regulators increasingly recognized that product safety depends not only on the final product but also on:
- battery quality
- manufacturing consistency
- supply chain management
- production process control
As a result, China introduced a new generation of CCC certification requirements for portable power products.
What Is GB 47372-2026?
GB 47372-2026 is China’s dedicated safety standard for portable power banks.
It works alongside:
- GB 4943.1-2022
- GB 31241-2022
The new framework significantly strengthens safety requirements for lithium battery products.
The regulatory philosophy is changing from:
Test the product and issue certification.
to:
Verify the entire manufacturing system before certification approval.
This represents one of the most significant changes in China’s portable power industry in recent years.

Old CCC vs New CCC
| Item | Previous CCC | New CCC |
|---|---|---|
| Certification Focus | Product testing | Full lifecycle supervision |
| Factory Audit | After approval | Before certification |
| Battery Abuse Tests | Basic | Comprehensive |
| Traceability | Limited | One product, one QR code |
| Quality Supervision | Periodic | Dynamic risk management |
| Supply Chain Requirements | Basic | Enhanced control |
The new system is considerably more demanding but also improves long-term product reliability.
New Battery Safety Tests
Traditional tests remain in place:
- Overcharge
- Short circuit
- Temperature rise
- Vibration
- Drop tests
However, the new standard introduces additional abuse testing.
Nail Penetration Test
Simulates internal battery short circuits.
Crush Test
Evaluates battery behavior under severe mechanical stress.
Thermal Abuse Test
Examines performance under extreme temperatures.
Lithium Precipitation Test
Detects abnormal lithium deposition that may increase fire risk.
These new tests significantly raise the technical barriers for manufacturers.
Why Thermal Management Is Becoming More Important
As charging power continues increasing to:
- 100W
- 140W
- PD 3.1
battery temperatures become increasingly difficult to control.
This is why intelligent thermal design has become a major competitive advantage.

Stricter Factory Audits
Perhaps the biggest change is the certification process itself.
Under previous rules:
Manufacturers could submit samples for testing.
Under the new rules:
Certification bodies may:
- conduct on-site inspections
- randomly collect samples
- perform unannounced audits
- evaluate manufacturing systems
Factories are also divided into different supervision levels with varying inspection frequencies.
This means stable mass production capability is becoming just as important as passing laboratory tests.
Supply Chain Requirements Are Expanding
The new rules extend safety management to upstream suppliers.
Manufacturers must increasingly evaluate:
- material consistency
- moisture control
- separator quality
- electrolyte stability
- battery cell traceability
For OEM buyers, this means supplier selection is becoming increasingly important.

One Product, One QR Code
One of the most important additions is mandatory traceability.
Each product may require a unique identifier that allows regulators and manufacturers to track:
- battery batches
- production date
- factory information
- quality records
- after-sales information
This creates a full lifecycle management system.
The objective is to improve:
- recall efficiency
- accountability
- product safety
What Does This Mean for Overseas Brands?
Foreign companies are fully eligible to apply for CCC certification.
However, brands should prepare for:
- additional documentation
- factory inspections
- Chinese-language materials
- longer project schedules
Estimated timeline:
8–12 weeks
Estimated cost:
RMB 40,000–50,000
Brands launching new products should allocate sufficient time for compliance planning.
Will Existing Products Need Recertification?
This depends on:
- certification validity
- product modifications
- implementation schedules
Manufacturers should consult certification bodies to determine whether existing products require updates.
How OEM Buyers Should Prepare
1. Evaluate factory quality systems.
2. Review battery suppliers.
3. Confirm traceability capabilities.
4. Prepare longer certification schedules.
5. Consider compliance during product development instead of after design completion.
The new CCC framework increasingly rewards manufacturers with strong engineering and quality systems.
Key Takeaways
China’s new CCC rules significantly raise safety requirements.
Product safety is no longer limited to laboratory testing.
Supply chain control is becoming increasingly important.
Traceability and factory management are now essential.
Compliance capability may become a major competitive advantage for OEM manufacturers.
