Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If salt form like sodium resinate
Rosin salts specifically classify under subheading 3806.10 rather than acid derivatives.
If chemical intermediate preparation
Preparations as intermediates for other chemicals may fall under 3824 chemical preparations.
If isolated cyclic alcohols extracted
Purified alcohol fractions from disproportionation classify as specific organic chemicals.

Import Tips & Compliance
• Submit GC-MS analysis showing stabilized isomer profile to distinguish from crude rosin
• Declare exact disproportionation degree (typically 90%+) for accurate duty assessment
• Monitor for FDA registration if used in food-contact applications like chewing gum base
