Subheadings
Products classified under Tariff item 2912.12.00
Acetaldehyde 99% Pure Industrial Grade
Acetaldehyde (ethanal, CAS 75-07-0) is a colorless, volatile liquid with a pungent fruity odor, presented as a separate chemically defined acyclic aldehyde without other oxygen functions. It is classified under tariff item 2912.12.00 as ethanal, consistent with Chapter 29 Note 1(a). This industrial grade is suitable for various chemical synthesis applications.
Acetaldehyde Anhydrous Technical Grade
Anhydrous technical grade acetaldehyde is a high-purity form of ethanal without water content, directly classifiable under tariff item 2912.12.00 as a separate acyclic aldehyde. It is primarily used in the production of acetic anhydride and other chemical intermediates, meeting Chapter 29 Note 1(a) for chemically defined compounds.
Acetaldehyde Bulk Tanker Grade 98%
98% acetaldehyde suitable for bulk tanker transport in chemical manufacturing is classified under tariff item 2912.12.00 as the chemically defined acyclic aldehyde, allowing minor impurities. It is used in large-scale production of vinyl acetate and other industrial chemicals, consistent with Chapter 29 Note 1(a) for separate chemically defined compounds.
Acetaldehyde for Flavor and Fragrance Synthesis
High-purity acetaldehyde specifically for synthesizing apple, pineapple, and rum flavor compounds is classified under tariff item 2912.12.00 as the pure chemically defined acyclic aldehyde. It meets food-grade precursor standards and is used in flavor and fragrance synthesis, consistent with Chapter 29 Note 1(a).
Acetaldehyde Stabilized with Hydroquinone
Stabilized acetaldehyde contains a small amount of hydroquinone to prevent polymerization during storage and transport, remaining classified under tariff item 2912.12.00 as the pure acyclic aldehyde per Chapter 29 Note 1(f). The stabilizer is added solely for preservation and does not make the product suitable for a specific use.
Acetaldehyde with MEHQ Inhibitor
Acetaldehyde inhibited with 4-methoxyphenol (MEHQ) at 100 ppm to prevent oxidation is classified under tariff item 2912.12.00 per Chapter 29 Note 1(f), which allows added stabilizers necessary for preservation or transport. It is used in polymer and resin industries, and the stabilizer does not render it suitable for a specific use.
Industrial Acetaldehyde in Glass Ampoules
Acetaldehyde packaged in sealed glass ampoules for laboratory and small-scale industrial use is classified under tariff item 2912.12.00 as the pure acyclic aldehyde compound. The packaging is solely for safe transport without altering the product's classification, consistent with Chapter 29 Note 1(a).
Pharma-Grade Acetaldehyde GC Pure
Gas chromatography pure acetaldehyde meeting Ph. Eur. standards for pharmaceutical intermediate use is classified under tariff item 2912.12.00 as pure ethanal. It is an essential precursor for chloramphenicol and other antibiotics, consistent with Chapter 29 Note 1(a) for separate chemically defined compounds.
Research-Grade Acetaldehyde 99.5%
99.5% research-grade acetaldehyde for R&D applications in organic synthesis is classified under tariff item 2912.12.00 as the pure separate acyclic aldehyde. Supplied in 100g-1kg quantities for university and lab use, it meets Chapter 29 Note 1(a) for chemically defined compounds.
