Acetals and hemiacetals, whether or not with other oxygen function, and their halogenated, sulfonated, nitrated or nitrosated derivatives
2 declarable lines
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%.
Products in this heading
- 1,1-Bis(1-methylethoxy)cyclohexane
- Acetaldehyde diethyl acetal (1,1-diethoxyethane)
- Dimethoxymethane (methylal)
- Benzaldehyde dimethyl acetal
- 2,2-Dimethoxypropane (acetone dimethyl acetal)
- 1,1-Diethoxycyclohexane
- Hemiacetals such as the methanol hemiacetal of formaldehyde
- Brominated or chlorinated derivatives of the above acetals
How to choose the right subheading
- Confirm the molecule has an acetal or hemiacetal carbon, meaning one carbon bonded to two oxygen atoms.
- Check whether the acetal function is the only oxygen function or whether other oxygen functions are present; the heading covers both.
- Check for a ring formed only of carbon and oxygen; cyclic acetals of that type are classified outside this heading.
- Identify whether the goods are the named compound 1,1-bis(1-methylethoxy)cyclohexane or any other acetal or hemiacetal.
- Confirm whether the product is a defined compound rather than a mixture or preparation, which would be classified elsewhere.
Often confused with
- Heading 2912Acetaldehyde
It is an aldehyde, not an acetal, so it falls in the aldehyde heading.
- Heading 29321,3-Dioxolane
A cyclic acetal whose ring is heterocyclic goes to the heterocyclic oxygen heading.
- Heading 2915Ethyl acetate
It is an ester of a carboxylic acid, not an acetal.
- Heading 2909Diethyl ether
A simple ether with no acetal carbon belongs in the ether heading.
- Heading 2912Vanillin
It is an aldehyde with an ether function, classified as an aldehyde.
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%.
