The materials partner behind AI infrastructure.

Wan Su Tong Trading Limited is Asia’s core Chemours distributor, an authorized distributor for Covestro, SABIC, LG Chem, Teijin, DuPont and Colorant Chromatics™, and a full-category materials supplier to the manufacturers building the AI era — from data-center interconnect to the fabs, batteries and devices around it.

Who we are

We are a different kind of distributor: focused on the high end of the AI economy, and organised to supply it at scale.

WANSUTONG holds Asia’s core distribution position for Chemours fluoropolymers and is an authorized distributor for Covestro, SABIC, LG Chem and Teijin polycarbonate, DuPont engineering polymers and Colorant Chromatics™ fluoropolymer colourants. Fluoropolymers — PFA, PTFE, FEP, ETFE, PVDF — are the heart of the business, listed grade by grade, but the supply covers the full category: engineering plastics, special engineering plastics, and the specialty grades that sit behind high-frequency cable, liquid cooling, semiconductor wet processes and power electronics.

The company was incorporated in Shenzhen in December 2007 on a trading business that dates back to June 1997. Today it supplies more than ten thousand tonnes of material a year, worth billions of RMB, and runs three headquarters: North America, East Asia, and the Greater Bay Area in Hong Kong and Shenzhen.

Who we serve

Our customers are the companies whose names define the industries they work in. NVIDIA, Apple and Amphenol on the AI and interconnect side. BYD in energy and mobility. Aerospace programmes. SMOORE in atomisation devices. Major medical institutions, the food industry, and manufacturers across the wider industrial base.

Across that list runs one thread: we are the leading compliant materials supplier to the full AI infrastructure supply chain — the cable, connector, cooling, substrate and enclosure makers whose output ends up in the same racks. When a programme needs the same qualified grade at plants in China, Vietnam, Mexico and the United States, with documentation that satisfies each market, that is the supply we run.

Authorized at the source. Qualified at the customer. Delivered to whichever plant the programme is built in.

From Asia to the world

China remains the base of the supply. After the pandemic, WANSUTONG began opening overseas subsidiaries to carry the brands it holds in Asia out to where manufacturing was growing fastest — Mexico, Vietnam, and other regions and companies with a strong manufacturing trajectory. The customer base now spans the full range of plastics and the industry chains built on them.

That footprint is organised as three headquarters: a North America headquarters in New York, an East Asia headquarters, and the Greater Bay Area headquarters across Hong Kong and Shenzhen. A customer gets one relationship whether the receiving plant is in Guangdong or Guanajuato.

How the supply is organised

Brand authorizations give us the material and the producer’s documentation at the source. Three delivery models — Asia-direct, North America local, and supplier-direct with WANSUTONG coordinating — let each site take material the way its logistics and import handling prefer.

What travels with every lot is the paperwork a qualification file needs: technical and safety data sheets, a certificate of analysis, origin documentation, and RoHS and REACH statements where the producer issues them. Where a second source or an alternative grade is wanted, we bring candidates with their own data and put samples in the customer’s hands; qualification stays with the engineers who own the process.
