Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for the base halohydrin intermediate
Halogenated hydrocarbon derivatives classify earlier in Chapter 29 before phosphorus attachment.
If protonated salt form with mineral acid
Alkylated/protonated salts remain in subheading, but inorganic salt aspects may invoke note 3(C)(1).
If technical grade mixture <85% purity
Prepared binders/chemicals of 3824 capture impure mixtures excluded from pure compounds of Chapter 29.

Import Tips & Compliance
• Cycloalkyl esters require dimensional chain length certification (total ≤C10 equivalent)
• Register with US chemical inventory (TSCA) prior to import for manufacturing use
