Both perfumes (typically higher concentration of aromatic compounds) and toilet waters (lower concentration, often labeled eau de toilette or eau de cologne) fall within the single subheading 330300, so the distinction does not affect the HTS classification. It may, however, affect valuation and labeling requirements under FDA cosmetic regulations.

Perfumes and toilet waters are regulated as cosmetics by the FDA under the Federal Food, Drug, and Cosmetic Act. They must comply with ingredient labeling requirements and must not contain prohibited or restricted substances. Alcohol-based fragrances may also require coordination with the Alcohol and Tobacco Tax and Trade Bureau (TTB) depending on the denaturation status of the alcohol. Consulting a licensed customs broker is advisable for high-value or complex fragrance shipments.
