Products classified under HTS 3504.00.10.00
Whey Protein Isolate Powder
Whey protein isolate is a highly purified form of whey protein extracted from milk, containing at least 90% protein by weight after removal of fats, lactose, and other non-protein components. It falls under HTS 3504.00.10.00 as a protein isolate, nesoi, derived from dairy sources and used primarily as a dietary supplement. This classification applies to isolates prepared through processes like microfiltration or ion exchange.
Soy Protein Isolate
Soy protein isolate is produced by extracting protein from soybeans through alkaline extraction and acid precipitation, yielding a product with over 90% protein content and minimal soy carbohydrates or fiber. Classified under HTS 3504.00.10.00 as a protein isolate from vegetable sources, it is widely used in meat alternatives, bakery products, and nutritional shakes. The isolation process distinguishes it from lower-concentration soy concentrates.
Pea Protein Isolate
Pea protein isolate is isolated from yellow peas via wet fractionation, resulting in a minimum 85-90% protein powder free of starch and fiber. It is categorized under HTS 3504.00.10.00 as a nesoi protein isolate, popular in plant-based vegan supplements and meat analogs due to its complete amino acid profile. The high purification level qualifies it distinctly from pea protein concentrates.
Rice Protein Isolate
Rice protein isolate is derived from brown rice through enzymatic hydrolysis and separation, achieving 90%+ protein purity hypoallergenic for sensitive consumers. Under HTS 3504.00.10.00, it serves as a clean-label ingredient in hypoallergenic formulas, bars, and beverages. Its isolation removes rice bran oils and carbs, aligning with protein isolate definitions.
Casein Protein Isolate
Casein protein isolate is precipitated from skim milk, yielding a slow-digesting protein powder over 90% pure used in micellar formulations for muscle recovery. HTS 3504.00.10.00 covers it as a dairy-derived protein isolate, nesoi, distinct from renneted caseins in other headings. Its application in supplements and cheese production underscores its versatility.
Collagen Protein Isolate (Bovine)
Bovine collagen protein isolate is hydrolyzed from cow hides or bones to >90% protein peptides for joint health supplements and cosmetics. It qualifies under HTS 3504.00.10.00 as a nesoi protein isolate from animal sources, excluding chromed hide powder. The high purity and solubility make it ideal for beverages and skincare.
Hemp Seed Protein Isolate
Hemp protein isolate is extracted from hemp seeds via mechanical pressing and aqueous separation, providing 90% protein rich in omega-3s. Under HTS 3504.00.10.00, it is a plant-derived protein isolate used in vegan nutrition and baking. THC-free processing ensures compliance for food use.
Egg White Protein Isolate
Egg white protein isolate, or egg albumin isolate, is spray-dried from fresh egg whites to >90% protein for baking and sports nutrition. HTS 3504.00.10.00 includes it as nesoi, separate from unmodified egg albumins due to advanced purification. Its functional properties like foaming aid industrial food production.
Fava Bean Protein Isolate
Fava bean protein isolate is produced by milling and isolating protein from fava beans, achieving high purity for gluten-free applications. Classified in HTS 3504.00.10.00 as a legume protein isolate, it supports sustainable protein sources in extruded snacks and beverages. Removal of vicine/convicine enhances digestibility.
Myofibrillar Protein Isolate (Beef)
Myofibrillar protein isolate from beef muscle is purified via pH shifting and centrifugation for meat texturizing and supplements. HTS 3504.00.10.00 captures this animal protein isolate nesoi, used in restructured meats and functional foods. High actin/myosin content defines its muscle-like properties.
