Anyone involved in lithium battery exporting, custom design, or mass production knows this very well:
If a lithium battery is not certified, it cannot be shipped, exported, sold, or mass-produced. As a factory that has specialized in custom lithium battery manufacturing for many years, we deal with different certifications every single day. Today, we will explain all the required certifications, how they are classified, common mistakes, and the full certification process, all in one place.
Why Must Lithium Batteries Be Certified?
Lithium batteries are chemical hazardous goods by nature. They store high energy in a small space, and if the design, protection system, or materials are not qualified, they can easily cause thermal runaway, fire, or even explosion.
Because of these risks, countries around the world classify lithium batteries as Class 9 dangerous goods and apply strict regulations, including:
- UN unified transport regulations
- Mandatory UL safety standards in the United States
- CE + RoHS + REACH requirements in the European Union
- Independent and strict controls in Japan and the UK
The core goal of all these regulations is the same:
prevent safety accidents and block unsafe products from the market.
Certification Is Not Optional — It Is Mandatory
For manufacturers and brands, certification is a basic requirement, not a bonus.
Without proper certification:
- Logistics companies will refuse to ship
- Customs may hold or reject the goods
- Online platforms can remove the product
- Customers will refuse delivery
In many cases, this means the entire project is canceled and mass production becomes impossible.
Major Types of Lithium Battery Certification
Lithium battery certifications can generally be divided into five main categories:
1. Transport Certifications
This category focuses on safety during transportation, including air, sea, and land shipping.
Because lithium batteries are classified as dangerous goods, transportation involves high risk.
Only batteries that pass special transport certifications can be shipped legally and safely.
2. Safety & Performance Certifications
This is the most basic and most important type of certification.
Almost all lithium batteries, whether for domestic or international markets, must pass these tests.
They evaluate the safety performance and functional performance of the battery to ensure it meets minimum safety and quality requirements.
3. Country / Region-Specific Certifications
Different countries and regions have their own regulatory systems and certification standards.
Common examples include:
- CCC for China
- CE for the European Union
- UL for the United States
Only after passing these local certifications can a lithium battery be legally sold in that market.
4. Environmental & Material Compliance Certifications
As global environmental regulations become stricter, the materials used in lithium batteries are also under close control.
These certifications check whether the battery:
- Is environmentally compliant
- Contains restricted or harmful substances
They are especially important for exports to the EU, Japan, and South Korea.
5. Special Industry Certifications
Some applications require industry-specific certifications with higher standards.
For example:
- Custom lithium batteries for medical devices must meet medical industry regulations
- Lithium batteries for automotive use must pass automotive-related certifications
These certifications are highly targeted and usually much stricter than general requirements.
Common Transport Certifications for Lithium Batteries
UN38.3 Certification
This is the global pass for lithium battery transportation.
Without UN38.3, lithium batteries basically cannot be shipped legally.
Key points:
- Scope: Air / Sea / Land transport
- Purpose: Verify safety during transportation
- Main tests: High & low temperature, vibration, shock, short circuit, crush, etc.
- Importance: The basic requirement for all lithium battery shipments
IATA Certification
This is the mandatory standard for air transport of lithium batteries.
It answers one key question: Can the battery go on an airplane?
Key points:
- Scope: Air transport / air express
- Issued by: International Air Transport Association (IATA)
- Main role: Regulates air packaging, labeling, and handling rules
- Importance: Without IATA compliance, air shipment is not allowed
MSDS (Material Safety Data Sheet)
A required safety document that must accompany lithium battery shipments.
Key points:
- Document type: Safety data sheet (not a test certification)
- Contents: Materials, hazards, emergency handling, transport notes
- Used by: Logistics companies, airlines, customs authorities
- Importance: Incorrect or missing MSDS can block customs clearance and shipping
Common Safety & Performance Certifications for Lithium Batteries
IEC 62133 Certification
IEC 62133 is a globally recognized safety standard for lithium batteries and is the basic certification for portable electronic devices.
Key points:
- Applies to: Lithium batteries for portable devices (watches, earphones, smartphones, etc.)
- Main tests: Overcharge, over-discharge, short circuit, temperature cycling
- Markets: Most countries worldwide
- Importance: A common mandatory choice for exports and international projects
UL 1642 Certification
UL 1642 is a U.S. safety standard focused on lithium battery cells.
Key points:
- Applies to: Single lithium battery cells
- Main tests: Nail penetration, high temperature (around 130 °C), extreme failure conditions
- Market: United States
- Importance: A required cell-level certification for exporting cells to the U.S.
Battery Performance Certifications (e.g. IEC 61960)
In one sentence:
These certifications verify whether the battery’s performance meets requirements.
Key points:
Importance: Required to meet customer performance targets and project acceptance criteria
Test items: Capacity, cycle life, charge/discharge efficiency
Focus: Real-world usage performance
Typical requirements: Cycle life ≥ 300 / 500 cycles
Lithium Battery Certification Requirements in Different Countries and Regions
This is one of the most important concerns for customers, especially those doing export and custom lithium battery orders.
Certification rules vary by country and region, and if the wrong certification is chosen, the product may not pass customs clearance.
European Union (EU)
For lithium batteries exported to the EU, the key requirement is CE certification, which is mandatory.
CE covers safety, health, and environmental protection.
In practice, this means:
- Compliance with IEC 62133 for lithium battery safety
- EMC certification to ensure the battery does not interfere with other electronic devices
- RoHS and REACH environmental compliance, which must also be completed
United States
The U.S. market also has strict requirements.
Lithium batteries exported to the U.S. mainly need UL certification.
Common standards include:
- UL 1642 for lithium battery cells
- UL 2054 for lithium battery packs
- FCC certification for products involving electromagnetic compatibility
It is important to note that U.S. testing standards are strict and take more time, so we always plan certification early with our customers.
Japan and South Korea
In Japan, the core requirement is PSE certification.
PSE is divided into Specified and Non-Specified Electrical Appliances.
Lithium batteries fall under Non-Specified Electrical Appliances and must pass PSE certification to enter the Japanese market.
They must also comply with Japanese national standards such as JIS C 8715.
In South Korea, the key requirement is KC certification, which is similar to Korea’s version of CCC certification.
It is mandatory, and without KC certification, lithium batteries cannot be sold in Korea.
Other Regions
For other export destinations:
- Australia: SAA certification
- Canada: CSA certification
- India: BIS certification
We have rich experience supporting these certifications and will provide targeted certification solutions based on each customer’s export market.
Environmental & Material Compliance Certifications for Lithium Batteries
Environmental protection is now a global priority. As lithium batteries are a major part of electronic waste, their material and environmental compliance is receiving more attention than ever — especially in regions with strict regulations such as the EU, Japan, and South Korea.
As a responsible custom lithium battery manufacturer, we strictly control material selection and production processes, and actively help our customers complete the required environmental certifications.
Common Environmental & Material Compliance Certifications
