Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified by aldehyde function present in precursor
Functional group classification could prevail if heterocyclic nature disputed.
If containing odoriferous substances exceeding Chapter Note (g) limits
Additions for identification can't render product suitable for specific use like perfumery.

Import Tips & Compliance
• Label as 'chemical intermediate - not for direct fragrance use' to prevent retail packing misclassification
• Provide GC-MS analysis confirming isosafrole identity and absence of piperonal byproducts
• Verify DOT/UN proper shipping name and packaging for Hazard Class 6.1 toxic liquid

Isosafrole
Isosafrole is a heterocyclic compound with an oxygen hetero-atom in its methylenedioxy ring structure, chemically defined as 1,3-benzodioxole-5-propene. It falls under HTS 2932.91.00.00 as a specific compound within the category of other heterocyclic compounds with oxygen hetero-atoms only. Primarily used as a chemical intermediate in fragrance and pharmaceutical synthesis.
Isosafrole USP Grade
Pharmaceutical-grade isosafrole meeting USP standards for purity, used as an intermediate in synthesizing piperonal derivatives and other API precursors. Classified under HTS 2932.91.00.00 due to its specific chemical identity as a heterocyclic oxygen compound despite pharmaceutical end-use intent. Supplied in amber glass bottles with stabilizers only for transport safety.
Isosafrole Technical Grade 98%
Technical grade isosafrole with 98% purity containing characteristic impurities, still classified as the specific compound under HTS 2932.91.00.00 per Chapter Note (a). Used in bulk for synthesis of safrole derivatives and aroma chemicals. Supplied in ISO tanks or 200L drums.
Isosafrole with Stabilizer for Transport
Isosafrole containing BHT stabilizer added solely for transport stability per Chapter Note (f), maintaining classification under HTS 2932.91.00.00. The stabilizer doesn't render it suitable for specific use beyond general chemical handling. Used in perfume intermediate production.
