Yes. Lithium batteries are classified as Class 9 Miscellaneous Dangerous Goods under international and national transportation regulations (such as the IATA DGR for air transport).
They are considered hazardous material (“hazmat”) for shipping because they pose a risk of:

• Short Circuit: Which can lead to overheating.
• Fire: If damaged, defective, or improperly packaged, they can catch fire.
• Explosion: A fire can lead to a rapid release of energy.

Consequently, their shipment is strictly governed by specific packaging, labeling, documentation, and quantity restrictions based on the mode of transport (air, sea, ground).

2. Why is the shipping cost for lithium batteries higher?

Shipping costs for lithium batteries are high due to the significant risks and specialized handling they require.

The primary reasons are:

• Hazardous Material (Dangerous Goods) Surcharges: Carriers add substantial fees to manage the inherent fire risk of lithium batteries.
• Specialized Packaging: Mandatory use of non-conductive, fire-retardant, and damage-resistant packaging to prevent short circuits and thermal events.
• Regulatory Compliance: Costs associated with required dangerous goods training, certified documentation, and specific labeling for each package.
• Limited Carrier Options & Segregation: Fewer carriers accept lithium batteries, and they often must be stored separately, adding logistical complexity.

In short, the high cost directly reflects the safety measures needed to mitigate the risk of fire during transit.
