Methyl Ester of Rosin (Methyl Rosinate) from China
Methyl ester of rosin, also known as methyl rosinate, is a low-viscosity liquid resin formed by esterifying rosin acids with methanol. It serves as a plasticizer in inks, coatings, and synthetic rubber compounds. HTS 3806.30.00.00 applies as it is a direct derivative of rosin acids via esterification.
