Products classified under Tariff item 2932.91.00
Isosafrole
Isosafrole is a separate chemically defined organic compound with a methylenedioxy ring structure, classified under tariff item 2932.91.00 as a heterocyclic compound with oxygen hetero-atoms. It is used primarily as an intermediate in the synthesis of fragrances and other organic chemicals. This product falls squarely within the scope of Chapter 29, Note 1(a), as a chemically defined compound.
Isosafrole Technical Grade 98%
Technical grade isosafrole with 98% purity is a separate chemically defined compound, even with characteristic impurities, per Chapter 29 Note 1(a). It is used in bulk for synthesizing safrole derivatives and other industrial chemicals. The product retains classification under tariff item 2932.91.00 as it is still isosafrole.
Isosafrole USP Grade
USP-grade isosafrole is a high-purity form of the compound, meeting pharmaceutical standards. It is used as an intermediate in synthesizing piperonal derivatives and other API precursors. As a separate chemically defined compound, it is classified under tariff item 2932.91.00.
Isosafrole with Stabilizer for Transport
Isosafrole with a BHT stabilizer added solely for transport is still classified under tariff item 2932.91.00, per Chapter 29 Note 1(f). The stabilizer does not render the product suitable for a specific use, maintaining its classification as isosafrole. This product is used in general chemical synthesis.
Piperonaldehyde Isosafrole Precursor
High-purity isosafrole marketed as a precursor for piperonal production is a separate chemically defined compound, classified under tariff item 2932.91.00. Its intended use does not affect classification, as the product is still isosafrole. It is used in the fragrance industry for synthesizing piperonal.
