HTS heading 2303 is a broad product category for certain residues and waste left over from food, starch, sugar, brewing, or distilling processes. It includes materials such as starch-manufacturing residues, beet pulp, bagasse, and brewing or distilling dregs and waste. These goods may be loose or formed into pellets, and they are often used as animal feed or as industrial inputs.
The 4-digit heading is only the starting point, not the final classification. To reach the correct 8-digit HTSUS subheading, identify the residue’s source and material, how it was processed, and whether a more specific subheading describes its type. Review the full legal description, including subordinate notes and any relevant units of quantity. If the product’s composition or processing is unusual, a customs broker or binding-ruling process may be appropriate.
What to check
- Identify the manufacturing process that produced the residue, such as starch production, sugar production, brewing, or distilling.
- Confirm the material’s exact composition and whether it is a single residue, a mixture, or has added ingredients.
- Check whether the product is loose, dried, or formed into pellets, and compare those facts with the wording of the available 8-digit subheadings.
- Use the complete HTSUS heading and subheading text, plus the General Rules of Interpretation and relevant notes; do not classify from the heading title alone.
- Keep product specifications, ingredient information, production-process records, and representative samples available to support the classification.

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.
