Related Products under HTS 3501.90.60.00

Sodium Caseinate Powder

Sodium caseinate is a water-soluble derivative of milk casein used primarily as an emulsifier and stabilizer in processed foods like coffee creamers and meat products. It falls under HTS 3501.90.60.00 as a casein derivative other than casein glues, distinct from caseinates specifically named elsewhere. This classification applies to its role as a food additive derived from milk proteins.

Calcium Caseinate Emulsifier

Calcium caseinate is a casein salt derivative valued for its emulsifying properties in non-dairy creamers and nutritional supplements. Classified under HTS 3501.90.60.00 as other casein derivatives, it excludes casein glues and focuses on industrial food applications. Its milk protein base and chemical modification define this tariff placement.

Casein Hydrolysate Powder

Casein hydrolysate is produced by enzymatic breakdown of casein into peptides for use in hypoallergenic infant formulas and sports nutrition. It qualifies under HTS 3501.90.60.00 as a casein derivative through hydrolysis, separate from unmodified casein or glues. This subheading captures hydrolyzed forms for pharmaceutical and food uses.

Micellar Casein Isolate

Micellar casein isolate is a purified, slow-digesting casein derivative used in protein powders for muscle recovery. HTS 3501.90.60.00 covers it as an other casein derivative due to isolation processes beyond basic casein. It remains distinct from glues or chapter exclusions like hardened proteins.

Rennet Casein Derivative

Rennet casein derivative is processed from rennet-precipitated milk casein for cheese production and nutritional uses. It fits HTS 3501.90.60.00 as other casein derivatives, excluding glues and prepared medicaments. The rennet treatment qualifies it as chemically modified.

Acid Casein Hydrolyzed Derivative

Acid casein hydrolyzed derivative undergoes acid precipitation followed by hydrolysis for use in adhesives and nutrition. Classified in HTS 3501.90.60.00 as other derivatives, it differs from casein glues which are specifically excluded to this subheading. Its dual-use profile fits industrial and food sectors.
