Product classification
HS code for Starch residues: 2303.10
Residues of starch manufacture and similar residues, whether or not in the form of pellets.
Classification of starch residues under HS 2303.10
Starch residues are classified under HS code 2303.10. This code covers the by-products resulting from the extraction of starch from various vegetable sources, such as maize (corn), potatoes, wheat, or cassava. During the wet-milling or extraction process, the starch is separated from the rest of the plant material, leaving behind residues that are rich in fiber and protein. These residues are primarily used in the animal feed industry. The classification 2303.10 specifically includes "residues of starch manufacture and similar residues." These materials may be presented in their natural moist state, dried, or in the form of pellets for easier handling and transport. The key to this classification is that the product must be a genuine waste product or by-product of the starch extraction process, rather than a primary product or a mixture of different feed materials.

Codes often confused with 2303.10
Common mistake. Starch residues are frequently misclassified under HS code 2302, which covers bran, sharps, and other residues from the sifting or milling of cereals. The distinction is the process: 2302 is for dry milling (flour production), while 2303.10 is for wet milling (starch extraction). Another error is using HS code 1108 for the starch itself; residues must be depleted of the primary starch content to fall under Chapter 23. Additionally, corn gluten meal is sometimes confused with corn gluten feed, though both generally fall under 2303.10.
Top exporters and importers of HS 230310 (the code used for starch residues), 2025
In 2025, the largest exporter of HS 230310 (the code used for starch residues) in UN Comtrade data was the United States, with 34% of world exports; the largest importer in UN Comtrade data was Indonesia, with 9.6% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 230310, not only starch residues.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about starch residues
What is the HS code for Starch residues?
The HS code for Starch residues is 230310 (Residues of starch manufacture and similar residues; whether or not in the form of pellets). The HS code for residues of starch manufacture is 2303.10.
How do I classify Starch residues for customs?
Starch residues is classified under HS code 230310 — Residues of starch manufacture and similar residues; whether or not in the form of pellets. This is a 6-digit subheading level code.
Does this code include residues from sugar production?
No, residues from sugar manufacture, such as beet-pulp or bagasse, are classified under HS code 2303.20, not 2303.10.
Which countries are the top exporters of starch residues (HS 230310)?
In 2025, the top exporters of HS 230310 (the code used for starch residues) in UN Comtrade data were the United States ($547M, 34% of world exports), China ($390M) and France ($96M). World exports came to about $1.6B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
