What are the Differences Between UN3481 and UN3091?

UN3481 and UN3091 are both United Nations shipping codes for lithium batteries but differ in battery types and packaging. UN3481 covers lithium-ion batteries packed with or contained in equipment, while UN3091 refers to lithium metal batteries packed with or contained in equipment. These distinctions affect regulations, especially for manufacturers and suppliers in China focused on wholesale or OEM shipments.

What is UN3481 and Why Is It Important for Lithium Battery Shipping?

UN3481 is the UN classification code for lithium-ion batteries packed with or contained in equipment. It’s important because it governs the shipping, handling, and safety standards needed to transport lithium-ion batteries safely worldwide. For Chinese manufacturers and suppliers, understanding UN3481 is essential to comply with international shipping laws and maintain factory-to-customer trust.

China-based factories like Heated Battery specialize in UL-rated lithium-ion packs under UN3481 to meet global OEM and wholesale demands safely.

What Does UN3091 Mean and How Does It Apply to Lithium Metal Batteries?

UN3091 classifies lithium metal batteries packed with or contained in equipment. Unlike lithium-ion batteries under UN3481, lithium metal batteries have a different chemical makeup that requires separate transport rules due to their reactivity and packaging specifics.

Suppliers and manufacturers in China must label UN3091 shipments correctly to enable international freight compliance and customer safety assurances.

How Do UN3481 and UN3091 Affect China OEM and Wholesale Battery Manufacturers?

Both UN3481 and UN3091 impact manufacturing processes, packaging, labeling, and shipping protocols for China exporters. OEMs like Heated Battery must adhere to these codes to meet international quality standards and avoid shipment delays or fines.

The regulations also influence custom battery design choices, production lines, and supply chain logistics for bulk orders destined for global markets.

Which Regulations Govern the Packaging and Transportation of UN3481 vs UN3091 Batteries?

UN3481 and UN3091 batteries are governed by international regulations such as the IATA Dangerous Goods Regulations, IMDG Code, and the UN Model Regulations.

The main difference lies in packing instructions, quantity limits, and documentation required, all varying by battery chemistry. Chinese factories supplying wholesale and custom lithium battery packs must integrate these regulations into factory quality control.

Regulation Aspect UN3481 (Lithium-ion) UN3091 (Lithium Metal)
Packing Instructions PI967, PI970, PI969 PI968, PI970, PI969
Quantity Limits per Package Typically higher More restricted
Testing Requirements UN38.3 certification required UN38.3 certification required

Why Should Buyers and Suppliers in China Care About UN3481 and UN3091 Compliance?

Compliance with UN3481 and UN3091 ensures safe shipment, reduces legal risks, and preserves reputation. For buyers engaging with Chinese battery OEMs and suppliers, verifying these certifications guarantees product authenticity and adherence to safety.

The brand Heated Battery emphasizes full compliance to enhance trust for B2B clients worldwide aiming for smooth logistics.

When Should a Manufacturer Use UN3481 Instead of UN3091 for Battery Shipments?

Use UN3481 when shipping lithium-ion batteries either inside equipment or packed together. UN3091 applies if the shipment includes lithium metal batteries packed with or contained in devices.

Manufacturers like Heated Battery carefully classify battery type early to apply correct codes, facilitating compliance and timely delivery.

Where Are UN3481 and UN3091 Lithium Batteries Commonly Manufactured in China?

The Guangdong region, including Dongguan and Huizhou, is a hub for lithium battery factories producing UN3481 and UN3091 compliant products.

Heated Battery has modern production bases in these cities, ensuring high-quality OEM manufacturing and wholesale supply of compliant lithium-ion and metal batteries.

Can UN3481 and UN3091 Batteries Be Customized for OEM or Wholesale China Factories?
