How to Ship Batteries: A Complete Guide for Global Logistics

Shipping batteries—especially lithium batteries—requires strict compliance with international transport regulations. Whether you are shipping by sea or by air, understanding the rules and required documents helps prevent delays, fines, and safety issues. This guide explains the process simply and clearly, making it easier for shippers to comply with global shipping regulations.

1. Understanding Battery Types: NON-DG vs. DG

Before preparing your shipment, you need to classify your batteries:

NON-DG (Non-Dangerous Goods) Batteries:
- Batteries with Watt-hour (Wh) rating under 100Wh.
- Generally considered safe for transport but still require documentation.
DG (Dangerous Goods) Batteries – Class 9:
- Batteries above 100Wh.
- Classified under UN3480 or UN3481, depending on packaging.
- Require stricter documentation and special handling.

Even if your battery is classified as NON-DG, you still need to follow procedures and obtain approvals before booking space for shipment.It’s not just the size (Wh) that matters. The number of batteries, packaging, and whether the battery is installed in equipment or shipped separately all affect classification.

2. Key Shipping Documents for Battery Transport

Whether you are shipping a NON-DG or DG battery, these documents are necessary:

a. MSDS (Material Safety Data Sheet)

Provides detailed safety and chemical information about the battery. It is required by both airlines and shipping lines.

b. UN38.3 Test Report

This test, required by the UN Manual of Tests and Criteria, ensures lithium batteries can withstand transport conditions. It’s a must-have for all lithium battery shipments.

c. 1.2 Meter Drop Test Report

Demonstrates the battery’s ability to withstand accidental drops. Commonly requested to ensure packaging safety, especially for e-commerce shipments.

d. 3M Stacking Test Report

This test confirms that battery packaging can endure pressure from other goods stacked on top. It’s essential for both sea and air freight.

e. Identification and Classification Report

Issued by certified labs, this report identifies the battery type and confirms its classification for transport. Necessary for customs clearance and space booking.

f. Dangerous Goods Declaration (if applicable)

Required for Class 9 batteries.

g. Air/Sea Shipping Labels & Marks

Proper labeling ensures handlers know how to treat the cargo.

3. Sea vs. Air Shipping: What’s the Difference?

Air Freight:
- Faster but has stricter regulations.
- Airlines require all test reports and may ask for packaging photos.
- Class 9 DG batteries need to be declared and often placed in special cargo sections.
Sea Freight:
- Slower but allows bulk shipping.
- Still requires full documentation.
- Special stowage locations must be arranged, regardless of battery classification.

Note: Booking space for both air and sea freight requires prior document checking and approval. This ensures the cargo can be assigned a compliant and safe location on the vessel or aircraft.

4. Booking Space: Document Checking is Key

Whether your battery is classified as NON-DG or DG, shipping lines and airlines will not allow the booking unless your documents are reviewed and approved.

What logistics providers will check:

Validity of MSDS (usually within 1 year)
UN38.3 report matching battery model
Drop and stacking test reports for packaging safety
Classification report matching battery specs

After approval, the shipping agent will apply for a special cargo location, especially for DG batteries which must be loaded on deck or in designated cargo areas.

5. Practical Tips for Shipping Batteries

Plan Early: Document preparation can take several days to weeks.
Use Certified Labs: Only reports from recognized laboratories will be accepted.
Partner with Experienced Logistics Providers: They will help review your documents and avoid costly delays.
Ensure Proper Packaging: Even NON-DG batteries must be properly packed to meet drop and stacking standards.

6. Summary Checklist: Documents You Need

Document	Required for NON-DG	Required for DG (Class 9)
MSDS	✅	✅
UN38.3 Test Report	✅	✅
1.2M Drop Test Report	✅	—
3M Stacking Test Report	✅	—
Identification & Classification Report	✅	✅

7. Rail Freight for Batteries

Rail freight is growing in popularity, especially from China to Europe.

Class 9 Batteries:
- Require full documentation (MSDS, UN38.3, DG declaration).
- Approval needed before booking.
Non-DG Batteries:
- Easier to move, but still require correct labels and paperwork.

Note: Not all rail routes accept DG cargo. Always confirm with your logistics provider.

8. Common Mistakes to Avoid

Missing Documents: Not having the UN38.3 or MSDS causes delays or rejections.
Incorrect Classification: Under-declaring a DG battery can lead to fines or bans.
Improper Labels: Missing or wrong labels cause customs issues.
Wrong Packaging: Non-compliant packaging is a safety risk and may be refused.

9. Partner with Experts for Smooth Shipping

Battery shipping is technical, and rules change often. Work with a logistics provider experienced in:

Lithium battery transport regulations
Documentation and DG declarations
Booking air, sea, and rail freight with compliance support
Warehousing and packing services in China or globally

Conclusion

Shipping batteries isn’t just about placing them in a box and sending them off. Whether they are NON-DG or DG batteries, Whether you’re shipping a power bank or an electric vehicle battery,comprehensive documentation and pre-approval are essential. Understanding the classification, preparing the correct reports, and coordinating with logistics experts will ensure your shipments are safe, legal, and efficient.
