Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with plasticizers or supplied as a formulated mixture exceeding 10% concentration
Mixtures of organic chemicals not chemically defined fall under Chapter 38 prepared binders; chapter notes exclude mixtures from pure compound headings.
If imported as a different halogenated cyclic hydrocarbon isomer
Other halogenated cyclanic derivatives are classified under 2903.59; specific naming in 2903.89.40.00 takes precedence per numerical order rule.
If put up in forms or packings specifically for retail sale as disinfectant goods
Chapter 38 covers goods put up for retail; chapter 29 notes exclude such preparations from pure chemical classification.

Import Tips & Compliance
• Verify TSCA pre-manufacture notice compliance and obtain EPA authorization for US imports due to HBCD restrictions under TSCA
• Include detailed chemical composition certificates and stereoisomer analysis to confirm classification under 2903.89.40.00
• Check Stockholm Convention compliance; HBCD is listed as a persistent organic pollutant requiring special handling permits
