Why buyers source this material
Buyers look for Sodium Metabisulphite — sodium pyrosulfite when they need a documented B2B source for water treatment (chlorine scavenging/dechlorination), food preservative (E223), brewing and winemaking, photography. Industrial buyers typically evaluate this material for production, formulation, cleaning, water-treatment or process-support requirements. Final suitability depends on confirmed grade and documentation. Raw Materials Trade Kft. positions the enquiry around confirmed documentation, availability and a suitable procurement route rather than consumer-style online checkout.
