Last updated: September 2026 dataSalicylic acid esters not covered by the aspirin heading include compounds such as phenyl salicylate (salol), odoriferous and flavoring salicylates, and a range of industrial derivatives — each routed to a distinct 10-digit line based on end-use and chemical identity. The US schedule specifically carves out salol suitable for medicinal use (2918231000) and odoriferous or flavoring compounds (2918232000), reflecting the divergent regulatory pathways these materials face. India and China together account for the bulk of US import volume under this heading, with Mexico also a notable supplier.

When imported in a form suitable for medicinal use, phenyl salicylate falls under 2918231000. Material intended for industrial applications such as UV stabilization in plastics or coatings, which does not meet pharmaceutical-grade specifications, would generally be classified under the non-medicinal residual lines. The importer's documentation of intended end-use and the product's certificate of analysis are key to supporting the correct classification. Consult a licensed customs broker to confirm the appropriate line.
Line 2918232000 is reserved for salicylate salts and esters that function primarily as fragrance or flavor ingredients — for example, methyl salicylate (oil of wintergreen) used in perfumery or food flavoring. Compounds that do not serve an odoriferous or flavoring function, and are not specifically enumerated elsewhere, fall into the residual lines (2918233000 or 2918235000) depending on whether they are described in Additional US Note 3 to Section VI.
