Protein Concentrates & Textured Protein Substances

Textured soy protein concentrate (2106101000) and pea protein concentrate (2106105000) are explicitly broken out at the 10-digit level, reflecting their growing commercial importance as plant-based meat alternatives and food-ingredient inputs — a sector where sourcing origin and processing method are increasingly scrutinized by buyers. The residual line 2106109000 captures other protein concentrates and textured protein substances not elsewhere specified. Canada leads US imports under this heading, with China, Czech Republic, Netherlands, and Philippines also among the top suppliers. Some lines under this heading may be subject to Section 301 tariffs depending on country of origin, making origin documentation especially important for products sourced from China.
