HTS heading 3502 groups albumins and closely related products. It covers albumins such as egg or milk albumin, albuminates (salts or compounds made from albumin), other albumin derivatives, and certain whey-protein concentrates containing more than 80% whey proteins by weight when calculated on a dry-matter basis. The heading is about the product’s protein material and chemical form, not simply its marketing name.
To narrow the heading to a specific 8-digit HTSUS code, first identify the product’s exact type and composition. The subheadings generally distinguish products by material or form—for example, the source of the albumin, whether it is an albuminate or derivative, and whether a whey-protein concentrate meets the specified dry-matter threshold. Review the relevant 6-digit subheading and then the US 8-digit statistical breakout, using the product’s technical documents to match the description precisely.
What to check
- Obtain the ingredient specification, certificate of analysis, and manufacturing description; identify the protein source and whether the product is albumin, an albuminate, a derivative, or a whey-protein concentrate.
- For whey products, verify the protein percentage on a dry-matter basis, not merely the percentage shown on the retail label or calculated as shipped.
- Check whether the product is a pure ingredient or a preparation containing other materials, additives, flavors, or carriers; those facts may affect classification elsewhere.
- Compare the product’s physical and chemical form with every applicable 8-digit breakout, including distinctions for source and type, rather than choosing the code with the closest trade name.
- Keep supporting records and request a customs-broker or CBP classification review when the composition, dry-matter calculation, or heading choice is uncertain.
HTS heading 3502 summary
Albumins is a 4-digit product category containing 4 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 3502?
Albumins (including concentrates of two or more whey proteins, containing by weight more than 80 percent whey proteins, calculated on the dry matter), albuminates and other albumin 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.
