About HS Code 380630
Ester gums are crucial derivatives of rosin, produced by esterifying rosin or modified rosin with polyhydric alcohols like glycerol or pentaerythritol. This chemical modification significantly alters the properties of the original rosin, enhancing its heat stability, solubility, and compatibility with other polymers. In international trade, ester gums are highly valued as tackifiers and film-forming resins, making them indispensable in various formulations. They are widely used in the manufacture of adhesives (especially pressure-sensitive and hot-melt adhesives), chewing gum bases, lacquers, varnishes, and printing inks. Exporters are specialized chemical manufacturers, while importers are typically companies in the adhesive, coating, and food industries. The type of alcohol used and the degree of esterification determine the specific properties and applications of the ester gum, catering to diverse industrial needs.
Products Under This Code
Glycerol ester of rosin, Pentaerythritol ester of rosin, Methyl ester of rosin, Hydrogenated rosin ester, Polymerized rosin ester, Modified rosin ester
Real World Examples
DRT (pine chemicals), Kraton (pine chemicals), Eastman Chemical, Wuzhou Pine Chemicals, Lawter
Common Misclassification
Ester gums are distinct from raw rosin (380610) and salts of rosin (380620), as they involve a specific esterification process to create a new chemical entity with different properties.
Products Classified Under 3806.30
Industry
This code belongs to the Chemicals industry.
Trade Overview
China, the USA, and India are major producers and exporters, with Europe and other Asian countries being key importers for their adhesive and coating industries.
