How does the ban on sodium thiocyanate in dairy products affect its industrial market?
The 2011 ban on sodium thiocyanate as a non-edible additive in food, following the Huishan Dairy detection incident at 15.2 mg/kg, has created a clear regulatory divide between food and industrial applications. Raw milk naturally contains around 3 mg/kg, but the lack of an official national detection method complicates enforcement. For industrial buyers, this regulatory scrutiny has not dampened demand in core sectors like acrylic fiber spinning, pharmaceuticals, dyeing, and rubber processing. However, it has heightened quality control expectations from suppliers, particularly regarding purity and traceability. The incident also underscored that sodium thiocyanate is a toxic substance requiring careful handling, which reinforces the importance of sourcing from reputable producers with consistent specifications for industrial use.
