About heading 2932
Heterocyclic compounds with oxygen hetero-atom(s) only
Heading 2932 covers heterocyclic compounds that contain only oxygen as the hetero atom, meaning the ring structure has no nitrogen, sulfur or other hetero atom. The heading is split into three groups: compounds with an unfused furan ring (2932.11 through 2932.19), lactones (2932.20), and a residual group for other oxygen heterocyclics including safrole, piperonal and tetrahydrocannabinols (2932.91 through 2932.99). Most lines within these groups are further divided by specific chemical name, and then by aromatic versus non-aromatic character and end use such as pesticides or drugs.

Frequently asked questions
What is the HTS code for sucralose?
Sucralose is classified under 2932.14.00.00, which carries a general (MFN) rate of 3.7%.
What is the duty on tetrahydrofuran?
Tetrahydrofuran falls under 2932.11.00.00 and pays a general (MFN) rate of 3.7%.
How do I classify butyrolactone?
Butyrolactone is a lactone other than an aromatic one, so it goes in 2932.20.50.10 at a general (MFN) rate of 3.7%.
