HTS heading 2914 is a broad product category for ketones and quinones, including versions that also have another oxygen function. It also covers certain derivatives that have been halogenated, sulfonated, nitrated, or nitrosated. In plain language, these are organic chemicals grouped mainly by their chemical structure and the modifications made to that structure—not by their brand name or intended use alone.
To narrow a product to an 8-digit HTSUS code, start with the heading and then follow the subheadings under it. The more specific lines commonly distinguish the substance by its chemical identity, form, or derivative type. Confirm the product’s exact composition and structure using its CAS information, molecular or chemical name, formula, purity, and technical documentation. The correct classification may require a customs broker or qualified classification professional, especially for mixtures, preparations, or products with multiple chemical components.
What to check
- Check the product’s exact chemical name, CAS number, formula, purity, and safety data sheet against the heading’s subheadings.
- Determine whether the item is a ketone, quinone, or a covered derivative, and identify any halogenated, sulfonated, nitrated, or nitrosated modification.
- Read every subheading under heading 2914 and compare the product’s specific material or chemical type with the wording of each provision.
- Do not classify solely by trade name, marketing description, end use, or packaging; verify the actual chemical composition and form.
- For mixtures, solutions, preparations, or ambiguous structures, obtain a customs-broker review or consider requesting an official classification ruling.
HTS heading 2914 summary
Ketones and quinones is a 4-digit product category containing 5 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 2914?
Ketones and quinones, whether or not with other oxygen function, and their halogenated, sulfonated, nitrated, or nitrosated derivatives. 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.
