About heading 2911

Acetals and hemiacetals, whether or not with other oxygen function, and their halogenated, sulfonated, nitrated or nitrosated derivatives

Heading 2911 covers acetals and hemiacetals, which are compounds built around a carbon atom bonded to two oxygen atoms, and it also covers the halogenated, sulfonated, nitrated or nitrosated versions of those compounds. The heading stays with the product even when the molecule carries another oxygen function. There are only two declarable lines: one named chemical at 2911.00.10.00, which is duty free, and a residual line 2911.00.50.00 for everything else at 5.3%.

Frequently asked questions

What is the HTS code for acetals and hemiacetals?

They fall in heading 2911. Any acetal or hemiacetal that is not the specifically named compound is declared under 2911.00.50.00, which carries a general (MFN) rate of 5.3%.

What is the duty on 1,1-bis(1-methylethoxy)cyclohexane?

It is classified under 2911.00.10.00, and the general (MFN) rate is Free.

How do I classify an acetal that also contains another oxygen function?

Heading 2911 covers acetals and hemiacetals whether or not with other oxygen function, so the extra oxygen group does not move the product out of the heading. Unless the goods are 1,1-bis(1-methylethoxy)cyclohexane under 2911.00.10.00 (Free), they are declared under 2911.00.50.00 at a general (MFN) rate of 5.3%.
