Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when CBP determines not covered by specific enumeration
Interpretative rulings may limit 'trichlorobenzenes' to major commercial isomers.
If classified as substituted chlorotoluene instead
Molecular structure interpretation affects parent hydrocarbon classification.
If pre-formulated as dye intermediate composition
Mixtures for specific manufacturing processes shift to Chapter 38.

Import Tips & Compliance
• Submit NMR spectrum confirming 1,2,3-isomer identity and isomeric purity
• Document synthetic pathway end-use to distinguish from commodity chemicals
• Include flash point data (62°C) for proper Class 3 flammable liquid declaration
