Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of sodium or potassium instead
Similar hydroxides of alkali metals classify under 2815, but strontium is alkaline-earth in 2816.
If as a chemical preparation for retail
Retail-packed chemicals shift from pure compounds to preparations in 3824.

Import Tips & Compliance
• Use COA to prove anhydrous state vs. octahydrate; mislabeling can lead to duty adjustments
• Comply with REACH-like TSCA pre-notice if >10,000 lbs/year imported
• Package in moisture-proof containers to prevent hydration during transit
