Ethylene Brassylate (MACROSTART™)
Ethylene brassylate is a synthetic macrocyclic lactone classified as an acyclic polycarboxylic acid derivative under HTS 2917.19.30.00 due to its chemical structure derived from brassilic acid. It is primarily used as a high-impact fragrance fixative in perfumes to provide long-lasting scent profiles.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported pre-mixed in final fragrance formulations
Mixtures containing 20%+ synthetic perfumery products fall under Chapter 33 as finished fragrance compounds rather than individual chemicals.
If supplied as diluted solution with proprietary solvents
Chemical preparations not elsewhere specified may classify under 3824 if the dilution renders it suitable for specific formulation uses beyond pure chemical transport.
If analyzed as saturated acyclic monocarboxylic acid derivative
Alternative chemical classification if structure interpreted differently from polycarboxylic lactone family.
