Xuchang Chengrui Insulation Materials Co., Ltd.

Client Background

Mr. Tran Van Nguyen, a seasoned electrical materials trader based in Ho Chi Minh City, had built his business supplying insulation components to Vietnam's growing electronics manufacturing sector. His company served mid-sized transformer and capacitor producers who demanded consistent quality PET films but struggled with unstable pricing from European suppliers.

The Procurement Pain Points

For three years, Nguyen faced sleepless nights over delayed shipments from his German supplier. The 18-22 week lead times forced him to maintain excessive inventory, tying up crucial working capital. When he explored local Vietnamese alternatives, the films often failed dielectric strength tests, causing embarrassing production halts for his clients. Price fluctuations from raw material volatility made quoting firm contracts impossible - he needed stability to grow his business.

The China Pivot

In early 2024, Nguyen attended Hanoi's International Electrical Expo where multiple manufacturers praised China's improved polymer technology. Skeptical but desperate, he began researching Chinese suppliers on google, filtering for manufacturers with ISO 9001 certification and UL recognition. This led him to Chengrui's detailed product page showcasing their expert specialization in electrical-grade polyester films.

Quality That Convinced

What stood out was Chengrui's transparent technical data - their 188μm film demonstrated 165kV/mm breakdown voltage, exceeding Vietnamese industry standards by 15%,. Test reports showed consistent thickness variation under ±3%, crucial for Nguyen's precision capacitor clients. Most importantly, Chengrui offered batch-by-batch third-party testing through SGS Vietnam, eliminating his quality verification headaches.

The Price Performance Balance

Compared to his German supplier's price, Chengrui's quoted at CIF Cat Lai Port included anti-static treatment - a feature Nguyen previously paid extra for. Their raw material hedging program locked prices for 6-month contracts, allowing Nguyen to finally offer stable pricing to his customers. The 35-day production cycle meant he could reduce inventory by 60%, freeing up nearly $120,000 annually.

Partnership Results

After two trial orders, Nguyen transitioned 80%, of his polyester film volume to Chengrui. His customers reported zero material-related defects in nine months of usage. The reliable supply chain helped him secure two new OEM contracts, growing his business by 37%, in 2024. Today, he recommends Chengrui to fellow traders at Vietnam's Electrical Traders Association meetings, praising how they "made a commodity feel premium through reliability."
