Acetaldehyde for Flavor and Fragrance Synthesis
High-purity acetaldehyde for flavor and fragrance synthesis is a separate chemically defined acyclic aldehyde. It is used as a precursor for apple, pineapple, and rum flavor compounds, and falls under tariff item 2912.12.00, provided it meets the purity standards for food-grade precursors.
Acetaldehyde Stabilized with Hydroquinone
Acetaldehyde stabilized with hydroquinone to prevent polymerization is classifiable under tariff item 2912.12.00 per Chapter 29 Note 1(f). The stabilizer is added for preservation or transport and does not make the product suitable for a specific use, so it remains a separate acyclic aldehyde.
Acetaldehyde with MEHQ Inhibitor
Acetaldehyde inhibited with 4-methoxyphenol (MEHQ) at 100 ppm is classifiable under tariff item 2912.12.00 per Chapter 29 Note 1(f), which allows added stabilizers necessary for preservation or transport. The inhibitor does not render the product suitable for a specific use.
