About HS Code 291100

This HS code covers acetals and hemiacetals, a class of organic compounds characterized by specific ether linkages. These chemicals are versatile, serving as protective groups in complex organic synthesis, components in fragrances and flavors, and intermediates for polymers and resins. For instance, polyvinyl butyral (PVB) is a well-known acetal polymer used in laminated safety glass. Importers and exporters range from fine chemical suppliers and pharmaceutical companies to manufacturers in the automotive and construction sectors. Their stability, specific reactivity, and ability to mask reactive aldehyde/ketone groups make them valuable in various niche and high-tech applications, driving a steady, specialized international trade.

Products Under This Code

Dimethoxymethane, 1,1-diethoxyethane, benzaldehyde dimethyl acetal, glycerol formal, polyvinyl butyral, paraldehyde

Real World Examples

Sigma-Aldrich Dimethoxymethane, BASF Glycerol Formal, Kuraray PVB (Polyvinyl Butyral)

Common Misclassification

Can be confused with ethers (2909) or even aldehydes (2912) from which they are derived, but the presence of two ether linkages to the same carbon atom is the distinguishing feature.

Industry

This code belongs to the Chemicals industry.

Trade Overview

Major trading countries include China, Germany, the USA, and Japan, reflecting their use in diverse industrial applications.
