Standalone mobile phone battery.

Typical rating:

15Wh.

Classification:

UN3480.

Applicable regulation:

PI965 Section II.

Requirements:

Risk factor:

Standalone mobile phone batteries are considered highly sensitive air cargo.

Many logistics channels restrict or reject them.

Case Study 2: Mobile Phones with Installed Batteries

Product:

Smartphone with battery installed.

Classification:

UN3481.

Applicable regulation:

PI967.

Transportation requirements are significantly lower because the battery is installed inside the device.

Case Study 3: Power Tool Replacement Batteries

One of the most common categories in cross-border e-commerce.

Example:

20V 5Ah battery.

20times5=100 Wh

This reaches the critical 100Wh threshold.

If the battery exceeds 100Wh, stricter dangerous goods regulations apply.

Packaging requirements:
