About HS Code 3501
Heading 3501 covers "Casein, caseinates and other casein derivatives; casein glues." This classification focuses on products derived from casein, a principal protein found in milk. Casein itself is obtained from skim milk through processes like acid precipitation (acid casein) or enzymatic coagulation (rennet casein). Caseinates are salts of casein, such as sodium caseinate or calcium caseinate, which are more soluble and functional than raw casein. The heading also explicitly includes other casein derivatives, highlighting its broad coverage of processed casein forms. Furthermore, glues formulated with casein as their primary adhesive component are classified here, distinguishing them from other animal glues. Casein and its derivatives have extensive applications: in the food industry as nutritional supplements, emulsifiers, and binders (e.g., in protein powders, processed meats, and infant formula); in industrial applications like paper coating, textile sizing, plastics manufacturing, and paints; and as specialized adhesives. Accurate classification is critical for trade compliance, as these products can be subject to specific food safety regulations, dairy import quotas, and sanitary and phytosanitary (SPS) measures, particularly when intended for human consumption. This heading is a cornerstone of Chapter 35, which groups albuminoidal substances and glues, emphasizing its protein-based nature and adhesive properties.
Products Under This Code
Acid casein, rennet casein, sodium caseinate, calcium caseinate, potassium caseinate, ammonium caseinate, hydrolyzed casein, casein protein powder, infant formula ingredients (casein-based), protein bars (casein-based), casein-based paint binders, casein glues for woodworking, casein-based paper coatings, casein plastics (raw material), photographic emulsions (casein component), textile sizing agents (casein-based), casein-based dietary supplements, caseinates for processed meats, casein for cheese making (as an additive), casein for leather finishing, edible casein, industrial casein.
Real World Examples
A major food manufacturer in Vietnam imports several tons of bulk sodium caseinate from New Zealand via ocean freight, to be used as a protein source and emulsifier in its range of nutritional supplements and processed food products. A specialized woodworking company in the USA imports high-quality casein glue from Germany for the restoration of antique furniture and for specific woodworking applications requiring strong, reversible bonds. A paper mill in Brazil imports acid casein from Ireland, utilizing it as a key ingredient for coating high-quality art and printing papers to enhance printability and gloss.
Common Misclassification
A common misclassification involves distinguishing casein from finished dairy products or other protein preparations. Traders might confuse casein with cheese or curd (0406), but 3501 specifically covers the isolated protein and its derivatives, not the finished food product. Another mistake is classifying complex food preparations containing casein under 3501; if casein is merely an ingredient in a broader food item (e.g., a protein bar mix), the finished product might fall under 2106 (Food preparations not elsewhere specified or included). Additionally, other protein substances not derived from casein should be classified elsewhere, such as 3504 (Peptones and their derivatives; other protein substances).

Trade Overview
Major exporters of casein and caseinates are dairy-rich nations such as New Zealand, Ireland, France, and the USA. Key importers include China, Southeast Asian countries, the USA, and EU member states, driven by demand from the food, pharmaceutical, and industrial sectors. These products are often subject to dairy import regulations, quotas, and strict sanitary certifications. Preferential tariffs are available under various free trade agreements, but compliance with food safety standards (e.g., HACCP, ISO 22000) is paramount for market access, especially for food-grade applications.

What are common misclassifications for HS code 3501?
A common misclassification involves distinguishing casein from finished dairy products or other protein preparations. Traders might confuse casein with cheese or curd (0406), but 3501 specifically covers the isolated protein and its derivatives, not the finished food product. Another mistake is classifying complex food preparations containing casein under 3501; if casein is merely an ingredient in a broader food item (e.g., a protein bar mix), the finished product might fall under 2106 (Food preparations not elsewhere specified or included). Additionally, other protein substances not derived from casein should be classified elsewhere, such as 3504 (Peptones and their derivatives; other protein substances).
Which countries trade the most under HS code 3501?
