USP Grade
Chemical Bulk Supplier

USP Grade (United States Pharmacopeia) is the highest commercial purity standard for chemicals used in pharmaceutical, cosmetic, food, and supplement manufacturing. USP-grade chemicals meet the purity, identity, and quality specifications published in the United States Pharmacopeia and National Formulary (USP-NF).

USP grade is required when:

• Manufacturing finished pharmaceutical products (FDA-regulated)
• Producing cosmetics under FDA cosmetic GMP
• Compounding pharmaceuticals at the retail or hospital level
• Food and beverage manufacturing requiring food-grade purity
• Dietary supplement manufacturing under DSHEA

• Technical Grade — industrial cleaning, manufacturing process inputs, water treatment. Purity ~90-95%.
• ACS Reagent Grade — research laboratories, analytical chemistry, R&D. Meets American Chemical Society specifications. Purity typically 99%+.
• USP Grade — pharmaceutical, cosmetic, food, supplement manufacturing. Meets USP-NF specifications. Purity 99%+ with identity verification.
• USP/FCC — food and beverage applications. Meets both USP and Food Chemicals Codex specifications.
