Zinc Pyrithione (CAS NO.: 13463-41-7) is supplied as a white to off‑white powder with a minimum purity of 99 % by Wuxi Hscical Co., Ltd, located in Wuxi, Jiangsu, China. The product conforms to an IR identity test and an assay of at least 98 % according to the supplier’s data sheet. It carries a molecular weight of 317.68 g·mol⁻¹, a melting point of approximately 240 °C and a measured pH of 6.5‑8.5 for a 5 % aqueous solution. The supplier’s trust tier is listed as “harbor” and the response rate is currently 0 %.
The compound is a broad‑spectrum antimicrobial and anti‑fungal agent widely used in architectural paints, coatings and construction sealants to inhibit mildew, algae and microbial growth. Its biocidal activity is effective in both water‑based and solvent‑based formulations, making it suitable for a range of industrial coating systems. Typical commercial grades are offered in powder form and as dispersions, allowing easy incorporation during manufacturing. Industry practice often requires compliance with hazardous class 6.1 regulations and packing group III for safe transport.
Buyers of Zinc Pyrithione are usually formulators in the coatings, adhesives and wood‑preservation sectors. The product is shipped in bulk containers or smaller drums depending on the buyer’s volume, and the supplier states that packaging options are available but does not publish minimum order quantities, lead times or exact incoterms. Prospective importers should request a current Certificate of Analysis and confirm the required shipping terms before placing an order. Payment methods and detailed logistics are negotiable with the supplier upon request.

Before placing an order, verify the current Certificate of Analysis, the IR spectrum report and the hazardous transport classification. Confirm that the material complies with any regional chemical regulations that apply to biocides in your market. These documents provide the factual basis for quality and safety assessments.
Logistics should be clarified with the supplier, including the preferred Incoterm (FOB, CIF or others), expected lead time and the method of payment. Because the listing does not disclose exact lead times, ask the supplier to provide a production schedule and shipping estimate. Ensure that freight forwarders are aware of the hazardous class 6.1 status and that appropriate safety data sheets accompany the shipment.
Quality control can be reinforced by arranging a third‑party inspection before loading. Request sampling for particle size distribution, purity re‑test and moisture content. Maintaining records of the inspection report, the MSDS and any compliance certificates will help streamline customs clearance and downstream processing.
