Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

7419Lower: 12.5% vs 30.5%

If alloyed with other metals

Lithium alloys exceed purity threshold for 2805, moving to Chapter 74 copper alloys or similar.

8545.11.00Higher: 37.5% vs 30.5%

If cut into battery anode discs

Pre-cut anode shapes for batteries classify as carbon electrodes under Chapter 85.

2815.12.00.00Higher: 37.5% vs 30.5%

If in aqueous solution

Dissolved lithium compounds fall under sodium hydroxide and similar subchapter II headings.

Import Tips & Compliance

• Provide material safety data sheets (MSDS) detailing reactivity with water; DOT requires Class 4.3 packaging

• Confirm thickness under 6mm to maintain 'unwrought' status; thicker sheets risk classification as plate

• Check end-use declarations to prevent diversion to restricted nuclear applications under export controls
