Chapter 23 covers residues and waste from the food industries and prepared animal feeding stuffs, including oil-cake, brewing or distilling residues, starch residues, etc. These goods are mostly processing by-products used for animal feed or industrial raw materials, distinguished from primary agricultural products such as oil seeds of Chapter 12 and cereals of Chapter 10. Heading 2303 includes residues from starch manufacture, similar residues, beet pulp, bagasse, etc. It specifically covers starch residues, bran, distillers' grains, etc., whether or not in the form of pellets. However, it excludes cereal flour presented separately of Chapter 12 or residues of other headings of Chapter 23. First 2 digits 23 = Residues and waste from the food industries; digits 3-4, 03 = Residues from starch manufacture, similar residues; digits 5-6, 10 = Starch residues. The full code 230310 refers to residues produced during starch production, usually wet residues, dried residues or pellets, used for feed. This product is a by-product of starch manufacture, not the grain itself, nor oil-seed residues. 230310 specifically refers to starch residues, distinguished from 2302 (residues from cereal flour) and 2304 (oil-cake). Therefore, it is classified under 230310.

Chapter 23 covers residues and waste from the food industries and prepared animal feeding stuffs, including oil-cake, brewing or distilling residues, starch residues, etc. These goods are mostly processing by-products used for animal feed or industrial raw materials, distinguished from primary agricultural products such as oil seeds of Chapter 12 and cereals of Chapter 10.
Heading
Heading 2303 includes residues from starch manufacture, similar residues, beet pulp, bagasse, etc. It specifically covers starch residues, bran, distillers' grains, etc., whether or not in the form of pellets. However, it excludes cereal flour presented separately of Chapter 12 or residues of other headings of Chapter 23.
Digit Breakdown
First 2 digits 23 = Residues and waste from the food industries; digits 3-4, 03 = Residues from starch manufacture, similar residues; digits 5-6, 10 = Starch residues. The full code 230310 refers to residues produced during starch production, usually wet residues, dried residues or pellets, used for feed.
Classification Basis
This product is a by-product of starch manufacture, not the grain itself, nor oil-seed residues. 230310 specifically refers to starch residues, distinguished from 2302 (residues from cereal flour) and 2304 (oil-cake). Therefore, it is classified under 230310.
📝 Declaration Elements
Product name: Declare the specific product name, such as 'corn starch residue', 'potato starch residue'. Composition content: State the main components (starch, protein, fiber, moisture) and their percentages. Source: Explain from what raw material (corn, potato, wheat, etc.) the starch is produced. Processing method: Describe whether it is dried, pelletized, crushed, etc. Use: Main use, such as animal feed, industrial raw material. Appearance: Color, form (powder, granules, wet lumps, etc.). Packaging specifications: Packaging method and weight per piece, such as 50kg/bag. Product name: Corn starch residue; Composition: starch 45%, protein 10%, fiber 20%, moisture 12%; Source: corn starch production; Processing method: wet residue dried and pelletized; Use: ruminant feed; Appearance: yellowish-brown granules; Packaging: 50kg/bag. Confusing starch residue with corn gluten meal, the latter classified under 2309. Not stating the raw material, may be misclassified as 2302 cereal residues. Ignoring the processing method; wet residue and dried residue have the same classification but must be distinguished in declaration.
Product name
Declare the specific product name, such as 'corn starch residue', 'potato starch residue'.
⚠️ Vaguely declared as 'feed' or 'starch'.
Composition content
State the main components (starch, protein, fiber, moisture) and their percentages.
⚠️ Only writing 'starch residue' without providing component ratios.
Source
Explain from what raw material (corn, potato, wheat, etc.) the starch is produced.
⚠️ Not stating the raw material type, leading to classification disputes.
Processing method
Describe whether it is dried, pelletized, crushed, etc.
⚠️ Omitting drying or pelletizing processes, affecting classification.
Use
Main use, such as animal feed, industrial raw material.
⚠️ Writing 'feed' but not specifying the feeding target.
Appearance
Color, form (powder, granules, wet lumps, etc.).
⚠️ Description inconsistent with the actual goods.
Packaging specifications
Packaging method and weight per piece, such as 50kg/bag.
Confusing starch residue with corn gluten meal, the latter classified under 2309.
Not stating the raw material, may be misclassified as 2302 cereal residues.
Ignoring the processing method; wet residue and dried residue have the same classification but must be distinguished in declaration.
🎯 Classification Logic
Classification basis: The product is a residue from starch manufacture, conforming to the description of heading 2303. Core determination: 1) Source is starch production; 2) Main components are starch, fiber, etc.; 3) Usually used for feed. If prepared into feed, it is classified under 2309. 230210 Corn bran, bran: 230210 is corn processing residue, but not starch residue; it is corn husk, germ, etc. 230240 Other cereal bran: 230240 is processing residue of other cereals, not specifically from starch production. 230400 Oil-cake: 230400 is residue after oil extraction, different source from starch residue. 230990 Other feed: 230990 is prepared animal feed; if starch residue is mixed with other ingredients, it is classified here. Is the raw material from starch production? Has it been prepared or mixed? Is the composition mainly starch? Is it used for feed? Is the processing method only drying/pelletizing?

❓ FAQ
What is the difference between starch residue and corn gluten meal? Starch residue is the residue after starch extraction, containing starch and fiber; corn gluten meal is the protein portion after wet milling corn to extract starch and germ, usually classified under 2309. The key difference lies in composition and use. Are the HS codes for wet starch residue and dry starch residue the same? Yes, both are classified under 230310. However, the processing method (wet residue, dried, pelletized) must be stated in the declaration, as customs may inspect moisture content. What documents are required for importing starch residue? Generally, a contract, invoice, packing list, bill of lading, and certificate of origin are required. If used for feed, an official quarantine certificate from the exporting country is also required, and it must comply with China's feed ingredient standards. How to inquire about the tariff rate for starch residue? You can check through the General Administration of Customs website or China International Trade Single Window by entering HS code 230310 to view the MFN rate, general rate, and VAT. Rates may change; refer to the latest announcement. Can starch residue be classified under 2309? If starch residue is prepared with added minerals, vitamins, etc., becoming a feed preparation, it should be classified under 2309. Pure starch residue is not classified under 2309. What are the declaration elements for starch residue? They include product name, composition content, source, processing method, use, appearance, and packaging specifications. Composition content must be specific to percentages, and source must state the raw material. Are the HS codes for starch residue and distillers' grains the same? No. Distillers' grains are classified under 230330, starch residue under 230310. Their sources differ: distillers' grains are brewing residues, starch residue is from starch production. Are there quarantine requirements for importing starch residue? Yes. As a plant-derived feed, it must comply with the Entry and Exit Animal and Plant Quarantine Law, provide a quarantine certificate from the exporting country, and may require an import animal and plant quarantine permit.
