Antiperspirants contain active drug ingredients (typically aluminum salts) that reduce perspiration, placing them under FDA's OTC drug monograph for antiperspirant drug products. Deodorants that only mask or neutralize odor without affecting perspiration are cosmetics. At entry, antiperspirant products require OTC drug labeling compliance and may be subject to FDA drug import review, whereas deodorant-only products face standard cosmetic oversight.

Burning odoriferous preparations, including agarbatti (stick incense), are specifically provided for under 330741. These products are generally not subject to FDA cosmetic or drug review, but certain incense products may be subject to Consumer Product Safety Commission (CPSC) oversight if they pose a safety hazard. Additionally, incense containing plant-derived materials may attract USDA APHIS scrutiny for agricultural pest risk.
