HTS heading 2301 is a 4-digit product category for animal- or aquatic-derived products that are not fit for human consumption. It groups flours, meals, and pellets made from meat or meat offal, fish, crustaceans, molluscs, or other aquatic invertebrates, along with greaves (cracklings), which are solid residues from rendering animal fat. The heading generally concerns processed materials used for animal feed, fertilizer, industrial processing, or similar non-food purposes—not ordinary food products.
To narrow the heading to a specific 8-digit HTSUS subheading, first identify the material and product form, then follow the relevant 6-digit and 8-digit branches. The classification may distinguish fish products from meat or meat-offal products and may further separate goods by the type of animal or aquatic source. Confirm the product’s composition, processing, intended use, and whether it is genuinely unfit for human consumption; the exact 8-digit choice can require customs-broker or classification-specialist judgment.
What to check
- Check the ingredient and species breakdown, including whether the product is made from fish, crustaceans, molluscs, other aquatic invertebrates, meat, or meat offal.
- Confirm the physical form: flour, meal, pellet, or greaves (cracklings), and review the manufacturing process and product specification.
- Verify that the goods are not fit for human consumption and keep records supporting that description, such as labels, technical sheets, and quality specifications.
- Read every applicable 6-digit and 8-digit branch in the current HTSUS rather than stopping at heading 2301; the correct code usually depends on the source material and other stated distinctions.
- Check agency requirements separately from tariff classification, especially animal-product, fish-and-wildlife, agriculture, labeling, and import-permit rules; consult a customs broker or binding-ruling process when the facts are uncertain.

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.
