Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If loose antimony trioxide powder
Pure chemical compounds like Sb2O3 classify in Chapter 28 as antimony oxides, not metal articles.
If premixed flame retardant preparation
Prepared chemical mixtures shift to Chapter 38, excluding single-chapter articles.
If incorporated into polymers
Flame-retardant masterbatch pellets are plastics of Chapter 39, not base metal.

Import Tips & Compliance
• Submit chemical assays; misclassification as Chapter 28 compound is common pitfall
• Label clearly as pellets vs powder to prevent reclass to 8110.10 unwrought
• Comply with TSCA for US plastic additive imports
