Products classified 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.
Casein Phosphopeptide Extract
Casein phosphopeptide extract is derived by enzymatic release of phosphorylated peptides from casein for dental health products. HTS 3501.90.60.00 includes it as a specialized casein derivative, avoiding chapter 30 medicaments. Its bioactive peptide nature supports nutraceutical applications.
Cross-Linked Casein Derivative
Cross-linked casein derivative features polymerized casein chains for biomedical coatings and slow-release fertilizers. It is covered by HTS 3501.90.60.00 as other derivatives, explicitly excluding hardened proteins of 3913. The cross-linking process defines its modified protein structure.
Glycosylated Casein Derivative
Glycosylated casein derivative attaches carbohydrates to casein via Maillard reaction for improved solubility in beverages. HTS 3501.90.60.00 accommodates this glycated form as other casein derivatives for food tech. It remains a protein derivative, not falling into sugar headings.
Casein Nanofibril Dispersion
Casein nanofibril dispersion involves nanoscale casein fibrils for edible films and drug delivery matrices. Classified under HTS 3501.90.60.00 as innovative casein derivatives excluding enzymatic preps of chapter 34. Its nanostructure enhances functional properties while maintaining protein classification.
Phosphorylated Casein Derivative
Phosphorylated casein derivative chemically adds phosphate groups to casein for mineral absorption enhancement in supplements. It falls within HTS 3501.90.60.00 as other casein derivatives for nutritional fortification. This modification targets bioavailability improvements.
Deamidated Casein Powder
Deamidated casein powder treats casein with acids or enzymes to remove amide groups, enhancing solubility for bakery emulsions. HTS 3501.90.60.00 captures this as a chemical derivative excluding chapter 34 washing preps. Used in clean-label food formulations.
Sulfated Casein Derivative
Sulfated casein derivative introduces sulfate groups for anticoagulant biomedical applications and cosmetics. Under HTS 3501.90.60.00 as other derivatives, it avoids chapter 30 medicaments via unfinished state. Supports heparin alternatives research.
Quaternized Casein Cationic Derivative
Quaternized casein cationic derivative adds positive charges for hair conditioning agents and antimicrobial films. HTS 3501.90.60.00 includes this charged protein derivative for personal care excluding chapter 34 preps. Enables substantive binding to negative substrates.
Casein-Glutathione Conjugate
Casein-glutathione conjugate covalently links antioxidant tripeptide to casein for functional beverages and oxidative stress protection. Classified HTS 3501.90.60.00 as conjugated protein derivative beyond simple mixtures. Enhances stability of labile glutathione.
