Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chemically modified with organic groups
Organo-inorganic derivatives fall under Chapter 29 per exclusion notes, not pure inorganic carbonates.
If only USP; non-USP to 2836.91.0050
Statistical suffix distinguishes USP from other lithium carbonates in the same heading.
If diagnostic reagents containing lithium carbonate
Lab diagnostic kits with carbonates classify as reagents under 3822 per Chapter exclusions.

Import Tips & Compliance
• Submit Drug Master File (DMF) references if applicable for API imports
• Test for heavy metals per USP <231> to comply with FDA
• Pitfall: bulk packaging without child-resistant features may trigger retail prep reclassification
