Ester gums

HS v2022 Code: 380630

About ester gums

HS code 380630 covers ester gums, which are a type of resin derived from natural sources. Ester gums are widely used in the production of various products, including adhesives, paints, inks, and coatings. They play a crucial role in the manufacturing industry, providing essential properties such as tackiness, flexibility, and durability. As a result, ester gums are an important component in the broader economy, supporting the production of a wide range of consumer and industrial goods.

Production process

Ester gums are typically produced through the esterification of natural resins, such as rosin or other terpene-based materials, with polyhydric alcohols. This process involves the reaction of the resin with the alcohol, resulting in the formation of the ester gum. The specific production techniques may vary depending on the desired properties and applications of the final product, but the core process of esterification remains the same.

Production inputs

The main inputs required for the production of ester gums include natural resins, such as 380610 Rosin and resin acids, and polyhydric alcohols, such as glycerol or pentaerythritol. Additionally, the production process may require various catalysts, solvents, and other chemical additives to control the reaction and achieve the desired properties. Specialized equipment, such as reactors, distillation columns, and drying systems, are also essential for the efficient and consistent production of ester gums.

Production outputs

The primary output of HS code 380630 is ester gums, which are then used as inputs in the production of a wide range of products. These include 350691 Adhesives based on polymers of headings 3901 to 3913 or on rubber, 320910 (Paints and varnishes (including enamels and lacquers) based on synthetic polymers or chemically modified natural polymers, dispersed or dissolved in a non-aqueous medium), 321110 Prepared driers, and 350510 (Dextrins and other modified starches (for example, pregelatinized or esterified starches); glues based on starches, or on dextrins or other modified starches). The versatility of ester gums makes them an essential component in various industries, contributing to the production of a diverse range of consumer and industrial goods.
