How we earn trust

Every batch is produced under an ISO 9001 quality system, tested before shipment, and shipped with COA, MSDS/TDS, and full export documents. When EU buyers ask for REACH compliance, we don’t guess — we provide documentation.

Our buyers include de-icing distributors, water-treatment formulators, and desiccant brands who reordered because the specification stayed the same from container No.1 to container No.50.

Integrated Logistics Support

To ensure reliable delivery for our clients, Pritech Group operates our own international freight forwarding division-pritech logistics. This gives us the ability to offer combined product + shipping solutions — so you can source and ship in one streamlined process.

Our logistics capabilities include:

Direct contracts with major carriers (COSCO, MSC, Maersk, CMA CGM, Evergreen)

Departure from Qingdao, Tianjin, Shanghai, Ningbo and Lianyungang

FOB, CIF, CFR, CIP, DAP and door-to-door delivery

Priority container allocation during peak season
