Heading 2922
Oxygen-function amino-compounds
72 declarable lines
Heading 2922 covers oxygen-function amino-compounds: molecules that carry an amine group plus at least one other oxygen function, such as an alcohol, phenol, aldehyde, ketone or carboxylic acid, including their salts and esters. It is split by the type of oxygen function present: amino-alcohols (2922.11 to 2922.19), amino-naphthols and amino-phenols (2922.21 to 2922.29), amino-aldehydes, amino-ketones and amino-quinones (2922.31 to 2922.39), amino-acids (2922.41 to 2922.49), and mixed amino-alcohol-phenols and amino-acid-phenols (2922.50). Within each group the lines run from individually named compounds down to residual Other lines, with drugs, photographic chemicals and fast color bases broken out separately.
Products in this heading
- Monosodium glutamate (flavor enhancer)
- Lysine and its salts (feed and supplement grade)
- Glycine
- Phenylephrine hydrochloride (decongestant)
- Diphenhydramine and its salts (antihistamine)
- Triethanolamine (pH adjuster and surfactant raw material)
- Monoethanolamine and diethanolamine
- Anthranilic acid and methyl anthranilate
How to choose the right subheading
- Identify the oxygen function attached to the molecule: alcohol, phenol, aldehyde, ketone, quinone or carboxylic acid. That picks the 2922.1x, 2922.2x, 2922.3x, 2922.4x or 2922.50 group.
- Check whether the compound is aromatic or non-aromatic; many groups split first on Aromatic versus Other.
- Check whether the exact chemical name appears in a named line in the heading before falling back to a residual Other line.
- Check whether the product is a drug (INN name or salt), a photographic chemical or a fast color base, since these are broken out with their own lines.
- Decide whether the goods are the base compound, a salt, or an ester, because separate lines and rates can apply to each form.
Often confused with
- Heading 2921Aniline and other amines with no oxygen function
Amine-function compounds without an additional oxygen function go to heading 2921.
- Heading 2923Benzalkonium chloride and other quaternary ammonium salts
Quaternary ammonium salts and hydroxides are classified in heading 2923.
- Heading 2924Acetaminophen (paracetamol)
It is a carboxyamide-function compound, so heading 2924 applies, not an amino-acid or amino-phenol line.
- Heading 2936Vitamin C (ascorbic acid)
Vitamins and their derivatives used primarily as vitamins are classified in heading 2936.
- Heading 2941Penicillins and other antibiotics
Antibiotics are classified in heading 2941 rather than as amino-compounds.
Frequently asked questions
What is the HTS code for monosodium glutamate?
Monosodium glutamate is classified under 2922.42.10.00, with a general (MFN) rate of 6.5%. Other glutamic acid and its salts fall under 2922.42.50.00 at 3.7%.
What is the duty on lysine imported for feed or supplements?
Lysine and its esters and salts are classified under 2922.41.00.10 when meeting Food Chemical Codex, Codex Alimentarius or United States Pharmacopeia requirements, at a general (MFN) rate of 3.7%. Other lysine falls under 2922.41.00.90, also at 3.7%.
How do I classify diphenhydramine?
Diphenhydramine (INN) and its salts are named in 2922.19.09.10, an amino-alcohol line for aromatic drugs, at a general (MFN) rate of 6.5%. Other aromatic drug amino-alcohols go under 2922.19.09.90 at the same rate.
