About HS Code 291250
This HS code specifically covers cyclic polymers of aldehydes, which are compounds formed by the polymerization of aldehyde monomers into a cyclic structure. The most common example is paraldehyde, a cyclic trimer of acetaldehyde. These polymers are traded for their unique properties, often serving as solvents, chemical intermediates, or even as sedatives in specific pharmaceutical applications. Importers typically include chemical manufacturers, pharmaceutical companies, and laboratories requiring stable, less volatile forms of aldehydes for various reactions or formulations. Exporters are generally chemical producers with the capability to synthesize and purify these specific polymeric forms. Key aspects of their trade involve ensuring the correct degree of polymerization, purity, and stability, as well as adherence to safety and regulatory standards, especially when used in pharmaceutical contexts. Demand is often niche but critical for specific industrial and medical applications.
Products Under This Code
Paraldehyde, Metaldehyde, Trioxane, Tetraldehyde, Cyclic acetaldehyde trimer, Cyclic formaldehyde trimer
Real World Examples
Sigma-Aldrich Paraldehyde, Merck KGaA Metaldehyde, TCI Chemicals Trioxane, BASF Paraldehyde
Common Misclassification
This code can be confused with the monomeric aldehydes themselves (e.g., acetaldehyde under 291219) if the polymeric nature is not clearly identified. It might also be mistaken for other non-cyclic aldehyde polymers (Chapter 39) if the cyclic structure is not emphasized.
Industry
This code belongs to the Chemicals industry.
Trade Overview
The United States, Germany, China, and India are key countries involved in the import and export of cyclic aldehyde polymers.

What are common misclassifications for HS code 291250?
This code can be confused with the monomeric aldehydes themselves (e.g., acetaldehyde under 291219) if the polymeric nature is not clearly identified. It might also be mistaken for other non-cyclic aldehyde polymers (Chapter 39) if the cyclic structure is not emphasized.
How is HS code 291250 structured?
HS code 291250 is a 6-digit subheading under the Harmonized System. The first 2 digits (29) identify the chapter, digits 3-4 (12) identify the heading, and digits 5-6 (50) specify the subheading. This code is standardized globally by the World Customs Organization.
