● Market size: Global food-grade and pharma-grade magnetic separation equipment market is expected to grow at 7 % CAGR from 2024 to 2028, reaching USD 1.1 billion.
● Growth engines: Rising food safety regulations, pharmacopeia purity limits, and consumer demand for “zero-metal” products.
● Regulations: US FDA Food Safety Modernization Act (FSMA), EU Regulation 2023/915, USP <788> & <789>, and ISO 22000.
“Every 1 ppm reduction in ferrous contamination cuts product recall risk by 30 % and extends shelf life by 10 %.”
Magnetic separators remove ferrous, stainless-steel, and work-hardened particles without chemicals, safeguarding brand reputation and regulatory compliance.
