HTS heading 7406 is a broad product category for copper in powder or flake form. It generally covers particulate copper products, rather than finished articles made from copper. The physical form matters: a powder and a flake may be treated differently under the tariff schedule, including based on the structure or shape of the particles.
To reach the correct 8-digit HTSUS code, start with the heading and then read the available subheadings and statistical suffixes. Confirm the product’s copper composition, whether it is pure copper or an alloy, and its physical characteristics—such as particle shape, size, and manufacturing method—against the wording and legal notes of the relevant subheading. The final classification may require customs-broker or other professional review when the product does not clearly match one description.
What to check
- Obtain the supplier’s technical data sheet, composition, and certificate of analysis before classifying the product.
- Confirm whether the merchandise is powder, flake, or another particulate form, and document particle shape and size when relevant.
- Read every subheading and statistical suffix under heading 7406; do not select an 8-digit code from the heading title alone.
- Check whether the product contains alloying elements, coatings, binders, or other materials that may affect classification.
- Verify the current HTSUS text and any applicable Chapter 74 notes, and seek a binding ruling or customs-broker advice if the classification is uncertain.
HTS heading 7406 summary
Copper powders and flakes is a 4-digit product category containing 2 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.

How do I choose the right code within this category?
