Have you ever faced this?

Your lithium battery products arrived at the port, but customs clearance was unexpectedly delayed or denied. This is often due to missing documents or improper packaging. As lithium batteries are classified as dangerous goods, they are subject to strict global regulations.

Three Essential Documents for Smooth Customs Clearance
1. UN38.3 Test Report

Includes 8 safety tests (short circuit, impact, overcharge, etc.)

Considered a “global passport” for safe transport

Mandatory for all lithium battery air/sea shipments

2. MSDS (Material Safety Data Sheet)

Details chemical composition, physical properties, handling, and emergency measures

Frequently required by customs and logistics providers

3. Transport Identification Report

Issued by a certified third-party agency based on UN38.3 results

Certifies compliance with international regulations (e.g., IATA, IMDG)

Tips to Avoid Pitfalls in Customs Clearance
1. Proper Packaging Is a Must

Batteries must be individually protected to prevent short-circuit

Packages with >24 batteries or >100Wh capacity require hazard labels

2. Verify the Testing Agency

Reports must be issued by labs with ISO 17025 accreditation

Otherwise, customs or carriers may reject the documentation

3. Consult Your Logistics Provider in Advance

Regulations may vary by country or port
