This article explains the key factors that affect STPP pricing, why food-grade STPP is usually more expensive than industrial-grade STPP, and how buyers can get accurate and competitive quotations.
1. Key Factors That Influence STPP Prices
STPP prices are not fixed. They fluctuate based on a combination of raw material, production, logistics, and market conditions.
1.1 Raw Materials and Energy Cost
- Phosphate rock price: the main raw material for STPP.
- Caustic soda and others: increase total production cost.
- Energy consumption: high-temperature calcination increases cost.
1.2 Supply–Demand Balance
- Seasonal demands from detergent and food sectors.
- Export changes and logistics delays affect supply stability.
1.3 Production Technology
- Modern equipment produces more stable quality and better yield.
- Higher processing efficiency may lead to lower price.
1.4 Currency & Logistics
- USD exchange rate fluctuations.
- Freight, container availability, port surcharges.

2. Industrial Grade vs Food Grade STPP – Why Prices Differ
Industrial and food-grade STPP share the same chemical formula but differ significantly in production, certification, and application safety.
2.1 Purity Levels
- Industrial: ≥ 94%
- Food grade: ≥ 95% with tighter impurity control
2.2 Production Environment
- Food grade requires HACCP or ISO22000 environments.
- More frequent sampling/testing increases production cost.
2.3 Application Risk
- Food grade used in meat, seafood, noodles → higher safety requirement.
