Customized Sourcing: Food Grade Sodium Nitrite with Anti-Caking Agent for EU Market
Typical Buyer Need
A European food-industry buyer needed food-grade sodium nitrite with high purity, reliable anti-caking performance, and suitability for European food-related applications. The key challenge was that no Chinese producer had ever added an anti-caking agent to this product. It’s a new attempt, requiring both a workable formulation on product and a compliant logistics solution for DG (Class 5.1+6.1, UN 1500) to minimize caking risk during storage and sea shipment.
How Walsun Supports
Walsun worked closely with the buyer and the factory to turn a difficult sourcing requirement into a practical solution. We compared customer requirements with benchmark product standards, coordinated multiple rounds of sample testing, clarified testing methods, supported SGS third-party inspection, pushed process and mixing improvements, and optimized shipment handling with moisture-control measures. Production and mixing videos were also provided to help rebuild buyer confidence.
Typical Deliverables
-
Turn a difficult requirement into a workable solution
Support buyers when the challenge is not only finding a supplier, but making the product usable, stable, and suitable for the target application.
