HS Code for Rosin ester

Rosin esters, also known as ester gums, are classified under HS code 3806.30. Heading 3806 covers rosin and resin acids, as well as their derivatives. Rosin esters are produced through the chemical process of esterification, where rosin (derived from pine oleoresin) or resin acids are reacted with polyhydric alcohols like glycerol, pentaerythritol, or methyl alcohol. This chemical modification enhances the stability, oxidation resistance, and melting point of the rosin, making it suitable for industrial use in adhesives, coatings, and printing inks. Because these products are chemically modified derivatives of natural resins rather than simple mixtures or synthetic polymers of Chapter 39, they are specifically allocated to subheading 3806.30. The classification remains consistent regardless of whether the rosin source is wood rosin, gum rosin, or tall oil rosin, provided the resulting substance is an esterified product.

Products Included

• Glycerol esters of wood rosin (E445)
• Pentaerythritol esters of rosin
• Methyl esters of hydrogenated rosin
• Ester gums used in chewing gum base
• Rosin-based tackifiers for adhesives

Common Misclassification

Rosin esters are often confused with raw rosin (3806.10) or resin acids (3806.10). The distinction lies in the esterification process; 3806.10 is for the unmodified material. They may also be misclassified in Chapter 39 (Plastics) under 3907 or 3911, but since they are derived from natural rosin and specifically named in 3806.30, the Chapter 38 code takes precedence according to the legal notes.

FAQ

What is the HS code for rosin ester?

The HS code for rosin esters, or ester gums, is 3806.30.

Is food-grade ester gum classified differently?

No, even if the glycerol ester of wood rosin is used as a food additive (E445), it is still classified under HS code 3806.30.
