Heading 2926

Nitrile-function compounds

22 declarable lines

Heading 2926 covers nitrile-function compounds, meaning separate chemically defined organic molecules that contain a cyano group. The heading is split first by the named compound (acrylonitrile, 1-cyanoguanidine, fenproporex and the methadone intermediate, alpha-phenylacetoacetonitrile) and then, under 2926.90, by whether the compound is aromatic or not, with further breaks for specific named benzonitriles, pesticide uses, and a residual other line. Most lines carry a 6.5% general (MFN) rate, while several specific compounds and the non-aromatic residual line are free.

Products in this heading

Acrylonitrile
Dicyandiamide (1-cyanoguanidine)
Benzonitrile
Phthalonitrile
2,6-Dichlorobenzonitrile
Bromoxynil (3,5-dibromo-4-hydroxybenzonitrile)
Malononitrile
The methadone intermediate 4-cyano-2-dimethylamino-4,4-diphenylbutane

How to choose the right subheading

Confirm the molecule is a separate chemically defined compound with a cyano group, not a mixture or preparation.
Decide whether the compound is aromatic or non-aromatic: the 2926.90 subheadings split on this first.
Check whether the exact chemical name appears in a dedicated line, such as acrylonitrile, benzonitrile or malononitrile, before using a residual line.
For aromatic compounds, check the named benzonitrile and pesticide lines before falling to the residual other lines.
Check whether the compound is described in additional U.S. note 3 to section VI, which has its own line.

Often confused with

Aniline
It is an amine-function compound, not a nitrile.
Heading 2921
ABS resin pellets
A polymer of acrylonitrile falls in the plastics chapter, not as a separate nitrile compound.
Heading 3903
A formulated herbicide containing bromoxynil
The technical nitrile is named in 2926, but a preparation put up as a pesticide is classified as a formulated product.
Heading 3808
Methadone (INN)
The drug itself is an oxygen-function amino-compound; heading 2926 covers only the named intermediate.
Heading 2922

Frequently asked questions

What is the HTS code for acrylonitrile?

Acrylonitrile is classified under 2926.10.00.00. The general (MFN) rate for that line is 6.5%.

What is the duty on benzonitrile?

Benzonitrile falls under 2926.90.08.00 as an aromatic benzonitrile. The general (MFN) rate is 6.5%.

How do I classify bromoxynil?

The technical compound 3,5-dibromo-4-hydroxybenzonitrile is classified under 2926.90.23.00 at a general (MFN) rate of 6.5%. If it is put up as a formulated herbicide preparation rather than the separate compound, it is not classified in heading 2926.
