HTS heading 2306 covers oilcake and other solid residues left after extracting vegetable or microbial fats or oils. These byproducts may be whole, ground, or formed into pellets, and are commonly used as animal feed, fertilizer, or industrial inputs. The heading groups products by their basic source material, while excluding residues classified in headings 2304 or 2305.
To narrow the category, identify the plant, seed, nut, fruit, or microbial source and how the residue was produced. The relevant 8-digit subheading generally distinguishes the material or type of residue; in the US tariff, additional digits may then provide a more specific statistical classification. Product descriptions, processing records, and composition information should support the selected code.
What to check
- Confirm that the product is a solid extraction residue, rather than an oil, meal made by another process, or a different food or feed preparation.
- Identify the exact source material, such as the seed, nut, fruit, plant, or microbial material, using supplier specifications and production records.
- Check whether the product belongs in the exclusions for heading 2304 or 2305 before using heading 2306.
- Compare the product’s physical form—whole, ground, or pelletized—and any added ingredients or processing against the subheading descriptions.
- Verify the complete current US HTS code and applicable agency requirements; ask a customs broker or request a binding classification ruling if the material or process is unusual.
HTS heading 2306 summary
Oilcake and other solid residues is a 4-digit product category containing 6 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?
