HS Code 3501.10 – Casein
HS code 3501.10 is the 6-digit subheading for casein. It is used for acid casein, rennet casein, edible casein, industrial casein and milk protein concentrate (high casein).
What HS 3501.10 covers
This HS code specifically covers casein, a family of phosphoproteins found in mammalian milk, which is a vital ingredient in numerous industrial and food applications. Casein is primarily extracted from skim milk and processed into various forms, serving as a key component in dairy products, nutritional supplements, adhesives, paints, and plastics. International trade in casein is driven by its versatility and demand across the food, pharmaceutical, and industrial sectors globally. Major importers typically include countries with large food processing industries, significant demand for nutritional products, or manufacturing sectors utilizing casein as a binder or emulsifier. Exporters are predominantly dairy-producing nations with advanced processing capabilities. Key trade considerations involve quality standards, protein content, purity, and compliance with food safety regulations. The market is influenced by global dairy production trends, consumer demand for protein-rich foods, and the development of new industrial applications for this natural polymer.

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).
