Lithium Battery Shipping Guide for Freight Forwarders

Lithium batteries are classified as dangerous goods and are subject to strict international transport regulations. Whether shipping by air, ocean, or ground, freight forwarders must understand the proper classification, packaging, labeling, and documentation requirements to ensure compliance and avoid penalties.

FREIGHT DIRECTORY provides practical tools and industry resources to support logistics professionals navigating complex shipping requirements.

Lithium batteries are commonly divided into two primary categories:

  • Lithium Ion Batteries (Rechargeable)

  • Lithium Metal Batteries (Non-Rechargeable)

Each category carries specific UN identification numbers.

UN3480 vs UN3481

Lithium ion batteries are classified under:

  • UN3480 – Lithium ion batteries shipped alone

  • UN3481 – Lithium ion batteries packed with or contained in equipment

Lithium metal batteries are classified under:

  • UN3090 – Lithium metal batteries shipped alone

  • UN3091 – Lithium metal batteries packed with or contained in equipment

Understanding the difference between batteries shipped alone versus contained in equipment is critical, as packaging instructions and documentation requirements vary significantly.

IATA Regulations for Air Freight

When shipping lithium batteries by air, regulations are governed by the International Air Transport Association (IATA) Dangerous Goods Regulations (DGR).

Packing instructions commonly referenced include:

  • PI 965 – Lithium ion batteries (UN3480)

  • PI 966 – Lithium ion batteries packed with equipment

  • PI 967 – Lithium ion batteries contained in equipment

Shipments may fall under Section IA, IB, or Section II depending on watt-hour rating, quantity, and packaging configuration.

Air carriers may impose additional restrictions beyond IATA minimum standards, so freight forwarders should always verify airline-specific requirements before booking.

Documentation Requirements

Depending on classification, lithium battery shipments may require:

  • Shipper’s Declaration for Dangerous Goods

  • Lithium Battery Mark

  • Class 9 Hazard Label

  • Air Waybill notation

  • Safety Data Sheet (SDS)

Improper documentation is one of the most common causes of shipment delays and regulatory fines.

Ocean and Ground Transport

Ocean shipments follow International Maritime Dangerous Goods (IMDG) Code regulations, while ground shipments in the United States are governed by 49 CFR (Code of Federal Regulations Title 49) (DOT regulations).

Although ocean transport is generally less restrictive than air, proper classification and labeling are still mandatory.

Best Practices for Freight Forwarders

  • Verify watt-hour ratings before classification

  • Confirm state of charge (SOC) limits for air freight

  • Ensure packaging meets UN performance standards

  • Retain documentation copies for audit purposes

  • Stay updated on annual regulatory changes

Lithium battery regulations are frequently updated, and non-compliance can result in significant fines or shipment rejection.

Why Lithium Battery Compliance Matters

As global demand for electronics, EV components, and energy storage systems grows, lithium battery shipments continue to increase. Freight forwarders must remain knowledgeable and compliant to protect their customers and operations.

Lithium Battery Shipping FAQ

What is the difference between UN3480 and UN3481?

UN3480 refers to lithium ion batteries shipped alone. UN3481 applies to lithium ion batteries packed with equipment or contained in equipment. The packaging, documentation, and quantity limits differ depending on which classification applies.

Do lithium batteries always require a Shipper’s Declaration?

Not always. A Shipper’s Declaration for Dangerous Goods is required for fully regulated shipments (Section IA and IB under IATA). However, Section II shipments may not require a full declaration but must still meet packaging, marking, and documentation standards.

What is the watt-hour limit for lithium ion batteries shipped by air?

Lithium ion cells must not exceed 20 Wh per cell, and batteries must not exceed 100 Wh per battery for most Section II shipments. Batteries exceeding those limits are typically fully regulated and subject to stricter packaging and documentation requirements.

What is the state of charge (SOC) limit for air freight?

Lithium ion batteries shipped by air must not exceed 30% state of charge unless approved by the operator. This requirement reduces fire risk during transport.

Can lithium batteries be shipped by ocean more easily than air?

Ocean shipments generally follow the IMDG Code and are less restrictive than air shipments governed by IATA. However, proper classification, UN packaging, labeling, and documentation are still required.

What labels are required for lithium battery shipments?

Depending on classification, shipments may require:

  • Class 9 Hazard Label

  • Lithium Battery Mark

  • UN Number marking

  • Cargo Aircraft Only label (if applicable)

Incorrect labeling is a common cause of shipment delays.

Can damaged or recalled lithium batteries be shipped?

Damaged, defective, or recalled lithium batteries are subject to special provisions and are often prohibited from air transport. These shipments typically require special packaging and approval under stricter regulatory controls.

Do freight forwarders need dangerous goods certification to handle lithium batteries?

Yes. Personnel involved in preparing or accepting lithium battery shipments must be trained and certified under applicable dangerous goods regulations such as IATA, IMDG, or 49 CFR, depending on the mode of transport.

What happens if lithium batteries are declared incorrectly?

Mis-declared lithium batteries can result in shipment rejection, regulatory fines, airline blacklisting, or serious safety incidents. Compliance is critical for both operational and legal protection.

Regulations are updated annually. Always consult the most current edition of applicable dangerous goods regulations.
