Isosafrole Technical Grade 98%
Technical grade isosafrole at 98% purity contains characteristic impurities that do not alter its identity as a separate chemically defined compound. It is classified under tariff item 2932.91.00 as isosafrole, consistent with Chapter Note 1(a) which allows impurities.
Isosafrole with Stabilizer for Transport
Isosafrole with a BHT stabilizer added for transport is still classified under tariff item 2932.91.00, as Chapter Note 1(f) permits added stabilizers necessary for preservation or transport. The stabilizer does not make the product suitable for a specific use.
Piperonaldehyde Isosafrole Precursor
High-purity isosafrole marketed as a precursor for piperonal production is still isosafrole, a separate chemically defined compound. It falls under tariff item 2932.91.00, as the intended use does not affect classification under Chapter 29.
