How to Ship Lithium Batteries Internationally

Lithium batteries power modern global supply chains—from smartphones and laptops to electric vehicles and industrial equipment. However, despite their widespread use, international transport of lithium batteries is heavily regulated due to safety risks such as fire hazards and thermal runaway.

This guide explains how to ship lithium batteries internationally in compliance with global standards, including IATA Dangerous Goods Regulations, as well as carrier-specific requirements from  UPS Official Website,  DHL Official Website, and  IATA Official Website.

1. Why Lithium Batteries Are Regulated

Lithium batteries are classified as dangerous goods because they contain high energy density electrolytes that can:

• Overheat under pressure or damage
• Catch fire if short-circuited
• Explode under extreme conditions
• Produce toxic gases when burning

As a result, international transport is governed under strict frameworks such as:

• IATA Dangerous Goods Regulations (DGR)
• UN Recommendations on the Transport of Dangerous Goods
• IMDG Code (for sea freight)
• ICAO Technical Instructions (for air cargo)

2. Classification of Lithium Batteries

Understanding classification is essential before shipping.

2.1 Lithium-ion Batteries (Rechargeable)

Common in electronics and EV systems.

• UN3480: Lithium-ion batteries shipped alone
• UN3481: Lithium-ion batteries packed with or contained in equipment

2.2 Lithium-metal Batteries (Non-rechargeable)

Used in sensors, medical devices, and backup systems.

• UN3090: Lithium metal batteries shipped alone
• UN3091: Lithium metal batteries contained in equipment

Each classification determines packaging, labeling, and documentation requirements.

3. Key Regulatory Framework (IATA)

The most important global standard for air transport is the IATA Dangerous Goods Regulations.

IATA Dangerous Goods Regulations Overview

Key packaging instructions:

• PI 965 → UN3480 (lithium-ion batteries only)
• PI 966 → UN3481 (packed with equipment)
• PI 967 → UN3481 (contained in equipment)
• PI 968 → UN3090 (lithium metal batteries only)
• PI 969 → UN3091 (packed with equipment)
• PI 970 → UN3091 (contained in equipment)

IATA also defines:

• State of charge (SoC) limits (e.g., max 30% for cargo aircraft for UN3480)
• Watt-hour limits
• Cell vs battery thresholds
• Packaging performance standards (drop test, crush resistance)

---

4. Shipping by Air (Most Restrictive Mode)

Air transport has the strictest rules due to safety risks.

4.1 General Requirements

• Strong outer packaging (UN-certified if required)
• Individual protection against short circuit
• Non-conductive inner packaging
• Battery terminals insulated
• Shock-resistant packaging design

4.2 Documentation

• Shipper’s Declaration for Dangerous Goods (if applicable)
• Air Waybill (AWB)
• MSDS / SDS (Material Safety Data Sheet)
• UN number and proper shipping name

---

5. Shipping by Sea (Less Restrictive but Still Regulated)

Sea freight follows IMDG Code rules.

Key advantages:

• Higher quantity allowances
• Less restrictive SoC limits
• Lower cost for bulk shipments

However:

• Requires Class 9 hazardous labeling
• Must follow segregation rules in containers
• Fire suppression considerations onboard vessels

---

6. Carrier-Specific Requirements

6.1 UPS Requirements

UPS
UPS Lithium Battery Shipping Guidelines

UPS requires:

• Compliance with IATA or ADR regulations
• Proper UN labeling (Class 9 hazard label)
• Pre-approval for certain battery shipments
• Restrictions on standalone lithium-ion batteries by air
• Specific packaging instructions depending on watt-hour rating

UPS also prohibits or restricts damaged or recalled batteries.

---

6.2 DHL Requirements

DHL
DHL Dangerous Goods Guidelines

DHL Express follows strict acceptance rules:

• Lithium-ion batteries must comply with Section II or Section IA/IB of IATA DGR
• Mandatory safety documentation for air transport
• Packaging must pass UN performance standards
• Restrictions vary by country destination
• Battery testing summary may be required for large shipments

DHL is particularly strict on e-commerce lithium battery shipments.

---

7. Packaging Requirements (Critical Section)

Proper packaging is the most important compliance factor.

7.1 Individual Cell Protection

Each battery must be:

• Fully insulated
• Separated from conductive materials
• Wrapped in non-conductive material

7.2 Outer Packaging Standards

Must meet:

• Drop test resistance
• Stack load strength
• Vibration resistance
• Compression resistance

7.3 Hazard Prevention Measures

• No loose batteries inside boxes
• No movement during transport
• Use of anti-static bags
• Fire-resistant liners (recommended for high-risk shipments)

---

8. Labeling Requirements

All lithium battery shipments must include:

• Class 9 Hazard Label
• Lithium Battery Handling Label
• UN Number (UN3480 / UN3481 / UN3090 / UN3091)
• Proper Shipping Name
• Sender and receiver details

For air transport, additional marks may include:

• Cargo Aircraft Only label (if required)
• State of Charge indication (for UN3480 shipments)

---

9. Common Mistakes in Lithium Battery Shipping

Many shipments are rejected due to:

• Incorrect UN classification
• Missing labels
• Non-compliant packaging
• Incorrect watt-hour declarations
• Mixing damaged and normal batteries
• Failing to follow carrier acceptance rules

These mistakes often lead to delays, fines, or shipment destruction.

10. Best Practices for Compliance

To ensure smooth international shipping:

• Always verify UN classification first
• Use certified UN packaging materials
• Follow IATA DGR updates annually
• Work with experienced freight forwarders
• Pre-check destination country regulations
• Maintain complete documentation records

---

Shipping lithium batteries internationally requires strict compliance with global safety regulations and carrier-specific rules. Whether using air or sea freight, understanding UN classifications, packaging standards, and documentation requirements is essential to avoid delays and ensure safety.

By aligning with frameworks from  IATA, and logistics providers like  UPS and  DHL, shippers can significantly reduce risk and ensure smooth global transportation.
