Lab Grade Chrome Alum from Mexico
Lab-grade chrome alum is a high-purity chromium potassium sulfate dodecahydrate intended for laboratory reagents and crystal growth experiments. As a chemically defined double sulfate salt, it is classified as an alum under tariff item 2833.30.00. The product's purity does not change its classification, as chapter 28 covers separate chemical compounds regardless of grade.
