Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If converted to strontium nitrate derivative
Strontium salts like nitrates fall under 2840 for manganites/peroxides, differing from carbonates; material transformation changes heading.
If diammonium phosphate blended for fertilizers
Fertilizer mixtures containing strontium carbonates are classified in Chapter 31 per exclusions in Chapter 28 notes.
If for retail pyrotechnic charges
Products put up as pyrotechnic charges fall under 3815, excluding pure chemicals per Chapter 28 note (e).

Import Tips & Compliance
• Provide assay certificates confirming >95% SrCO3 to avoid scrutiny as mixtures; declare end-use to prevent dual-use concerns in pyrotechnics
• Ensure proper packaging to prevent moisture absorption during shipping, a common pitfall
