Products classified under HTS 3504.00.50
Egg White Protein Isolate
Egg white protein isolate (ovalbumin) purified from egg whites for baking and supplements. HTS 3504.00.50 as animal protein derivative nesoi, >90% pure. Replaces whole egg powder.
Keratin Protein Powder
Keratin protein powder hydrolyzed from feathers or hooves for hair/skin cosmetics and feeds. HTS 3504.00.50 covers this structural protein derivative nesoi. Industrial use in beauty formulations.
Mycoprotein Powder
Mycoprotein powder from fermented fungi (mycelium) protein for meat substitutes like Quorn. Classified HTS 3504.00.50 as other protein nesoi, fermentation-derived. High fiber-protein blend.
Rice Protein Powder
Rice protein powder is extracted and mildly hydrolyzed rice endosperm protein for gluten-free nutrition. HTS 3504.00.50 as other protein substance nesoi, separate from rice starches. Used in baking and hypoallergenic formulas.
Hemp Seed Protein Isolate
Hemp seed protein isolate extracted from hemp seeds, containing edestin protein for plant-based nutrition. Falls under HTS 3504.00.50 as protein substance nesoi post-extraction. THC-free for food/supplement use.
Casein Protein Powder
Casein is a milk-derived protein substance processed into powder form for use in nutritional supplements and food manufacturing. It falls under HTS 3504.00.50 as a protein substance and its derivative, nesoi, not specified elsewhere in the tariff schedule. This classification applies to its role as a functional ingredient rather than a finished food product.
Soy Protein Isolate
Soy protein isolate is a highly refined protein substance extracted from soybeans, used in meat alternatives and nutrition bars. Classified under HTS 3504.00.50 as other protein substances nesoi, distinct from starches or enzymes. Its isolation process qualifies it as a derivative for industrial food applications.
Whey Protein Concentrate
Whey protein concentrate is a byproduct of cheese production, concentrated to 35-80% protein for sports nutrition. It qualifies under HTS 3504.00.50 as a derivative protein substance nesoi, separate from unmodified dairy. Used primarily as an ingredient in shakes and bakery products.
Peptone Broth Powder
Peptone broth powder consists of hydrolyzed meat or casein proteins used as a nutrient base in microbiology labs. It is classified under HTS 3504.00.50 as peptones and derivatives nesoi for laboratory and fermentation applications. Not covered as finished media or medicaments.
Gelatin Hydrolysate Powder
Gelatin hydrolysate is enzymatically broken-down collagen protein used in joint supplements and cosmetics. Falls under HTS 3504.00.50 as other protein derivatives nesoi, distinct from sheet gelatin. Its hydrolyzed form serves functional health ingredient roles.
Collagen Peptides Powder
Collagen peptides are bioactive hydrolysates from bovine or marine sources for skin and beauty supplements. Classified HTS 3504.00.50 as protein derivatives nesoi, valued for low molecular weight absorption. Used in beverages and functional foods.
Hide Powder Chromed
Chromed hide powder is specially processed animal skin powder used in leather tanning trials and analysis. It precisely fits HTS 3504.00.50 as chromed hide powder, a niche protein substance for industry. Chromium treatment enhances its tanning evaluation properties.
Torula Yeast Autolysate
Torula yeast autolysate is a protein-rich hydrolysate from torula yeast used in flavorings and feeds. Though yeast-derived, its protein derivative nature places it in HTS 3504.00.50 nesoi per chapter exclusions. Primarily industrial flavor enhancer.
Meat Peptone Powder
Meat peptone powder is pancreatic digest of meat proteins for bacterial culture media in labs. HTS 3504.00.50 covers it as peptone derivative nesoi for microbiological uses. Essential nutrient source without being complete media.
Pea Protein Hydrolysate
Pea protein hydrolysate is enzymatically digested pea protein for hypoallergenic infant formulas and sports drinks. Classified HTS 3504.00.50 as vegetable protein derivative nesoi. Offers high digestibility over standard isolates.
