About SUMEC
Yangzhou, Jiangsu, China · Est. 2015
Our Story
Sumec Yangzhou International Co., Ltd. was founded in 2015 with a single focus: manufacturing premium heat exchange solutions for North American heavy-duty trucks. Based in Yangzhou, Jiangsu Province — China's industrial heartland for automotive components — we've grown from a small workshop to a 7-year Alibaba Gold Supplier serving customers in 80+ countries.
Our founding team came from OEM supplier backgrounds, having spent years manufacturing EGR coolers and oil coolers for Tier 1 automotive suppliers. We applied that OEM-grade manufacturing discipline to the aftermarket, creating products that meet or exceed original equipment specifications.
Today, SUMEC's product line covers 1,200+ OE numbers across EGR Coolers, Oil Coolers, and Aftercoolers for Ford, International/Navistar, Cummins, CAT, Mack, Volvo, Peterbilt, and Kenworth applications.
Our Values
Quality First
Every product is manufactured to OEM specifications and pressure-tested before shipment. We don't ship parts we wouldn't put in our own trucks.
Technical Depth
Our team understands diesel engine systems, not just heat exchangers. We provide technical support that goes beyond part numbers.
Long-Term Partnerships
We build relationships with distributors and fleet operators, not just transactions. Our 5.0 Alibaba rating reflects this commitment.
