HTS heading 2922 is a four-digit product category for oxygen-function amino-compounds. In plain language, it groups certain chemical compounds that contain an amino function (a nitrogen-containing chemical group) and an oxygen-containing function, such as an alcohol, phenol, ether, or carbonyl-related function. It is a classification heading, not one single product description or duty rate.
To reach the correct eight-digit HTSUS code, first confirm that the product belongs in heading 2922, then follow the subheading structure and product descriptions. The narrower code may depend on the compound’s chemical identity, form, composition, or stated type. Use the product’s chemical name, formula, CAS Registry Number, concentration, and technical specifications; the final classification may require customs-broker or other professional judgment.
What to check
- Confirm the product’s exact chemical identity and that it has both the relevant amino and oxygen functions before using heading 2922.
- Read the HTSUS subheadings and legal notes in sequence; do not choose an eight-digit code from a product name alone.
- Compare the product’s CAS number, chemical formula, purity, mixture status, and physical form with the wording of each candidate subheading.
- Check whether the product is a single chemical, a preparation, or a mixture, because that distinction can change classification.
- Document the manufacturer’s safety data sheet and technical specification, and seek a binding ruling or customs-broker advice when the wording or chemistry is unclear.
HTS heading 2922 summary
Oxygen-function amino-compounds is a 4-digit product category containing 10 published product-code lines in this snapshot. A heading does not carry one universal duty rate; classification must be narrowed to the line matching the product facts.
How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.

Common questions
What products fall under HTS heading 2922?
Oxygen-function amino-compounds. To classify a specific item you must pick the matching sub-category and 8-digit code above; the right choice usually depends on the material and construction of the product.
How do I choose the right code within this category?
Start from the sub-categories (typically divided by material—for example cotton versus man-made fibers), then open the active 8- or 10-digit code that matches the product. When unsure, a licensed customs broker or a CBP binding ruling can confirm the classification.
