Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pharmaceutical-grade with hormone-related specifications
Certain high-purity derivatives may fall under hormones/provitamins.
If labeled/meets food chemical codex standards
Dual-use purity levels trigger food-grade subheading.
If forming metal coordination salts
Chapter notes direct metal-organic salts to later numerical headings.
