Heading 2928

Organic derivatives of hydrazine or of hydroxylamine

5 declarable lines

Heading 2928 covers organic derivatives of hydrazine and organic derivatives of hydroxylamine, a narrow group of nitrogen compounds used as chemical intermediates, reagents and blowing agents. The heading splits first by two specifically named compounds, methyl ethyl ketoxime and phenylhydrazine, then by whether the remaining product is aromatic, and finally by whether the non-aromatic product is a drug or another product.

Products in this heading

Methyl ethyl ketoxime, an anti-skinning agent for paints
Phenylhydrazine, a laboratory and dye intermediate
p-Toluenesulfonyl hydrazide, a rubber blowing agent
2,4-Dinitrophenylhydrazine, an analytical reagent
Acetone oxime (acetoxime)
Cyclohexanone oxime, an intermediate for caprolactam
N,N'-Diphenylhydrazine, an aromatic hydrazine derivative

How to choose the right subheading

Confirm the molecule is an organic derivative of hydrazine or of hydroxylamine, not the inorganic parent compound.
Check whether the product is one of the two named compounds: methyl ethyl ketoxime or phenylhydrazine.
For other products, decide whether the structure is aromatic or non-aromatic.
For non-aromatic products, check whether the goods are drugs of chapter 29 use.
If no specific or aromatic provision applies, use the residual other line.

Often confused with

Hydrazine and hydrazine hydrate
The parent compound and its hydrate are inorganic, not organic derivatives.
Heading 2825
Hydroxylamine and its inorganic salts
Only organic derivatives of hydroxylamine fall in heading 2928.
Heading 2825
Diazo, azo and azoxy compounds
These nitrogen linkages have their own heading even when made from hydrazine.
Heading 2927
Caprolactam
The ring-closed lactam is a nitrogen heterocycle, not an oxime.
Heading 2933
Nitriles such as acrylonitrile
The nitrile function is classified in its own heading.
Heading 2926
