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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used primarily as soy flour or low-protein feed ingredient
Soybean residues or flours with under 90% protein are classified as oilcake or feed in Chapter 23.
If when incorporated into formulated food products or beverages
Protein isolates in finished food preparations shift to Chapter 21 based on principal use.
If chemically modified, e.g., hydrolyzed or textured for specific functionality
Modified protein derivatives fall under heading 3507 for enzymatically or chemically altered substances.

Import Tips & Compliance
• Provide extraction process specs and protein content analysis to substantiate isolate status versus concentrate
• Ensure GMO status declaration if applicable, as soy imports often face biotech scrutiny
• Comply with USDA labeling for allergen disclosure to prevent FDA import alerts
