Our Story

TANGSHAN SWIFTSEN INTERNATIONAL

Founded in Tangshan — one of China's key heavy-industry and machining hubs — Swiftsen focuses on one thing: reliable spare parts for agricultural machinery. We consolidate production from audited partner factories specialized in engine components, hydraulics, transmission parts, bearings, seals and belts, then deliver them consolidated to importers worldwide.

Our customers are importers, distributors and repair service companies in Central Asia, the Middle East, Russia, Africa and South America. They rely on us for consistent quality, honest pricing, and fast, professional communication — in English, Russian or Arabic.

Every order ships with inspection records. Every inquiry gets an answer within 12 working hours. That is the Swiftsen standard.
