Xuchang Chengrui Insulation Materials Co., Ltd.

Ana Silva, owner of ‌Insul Tech Brasil‌, a São Paulo-based distributor of electrical insulation materials, faced mounting pressure in 2023. Her company, founded in 2016, had built a loyal clientele in Brazil’s manufacturing sector, supplying PVC fiberglass sleeving to automotive workshops and industrial equipment producers. But soaring domestic production costs and unreliable local suppliers put her business at risk. Delays in raw material deliveries, inconsistent sleeve quality and sudden price increases strained her relationships with clients.

Ana knew she needed a change. Local manufacturers couldn’t meet her demand for high-temperature-resistant sleeves and European suppliers quoted prices far beyond her budget. After researching global markets, she turned her attention to China, where PVC fiberglass sleeving production was renowned for its scalability and cost efficiency.

Her search began on industry forums and google. One evening, while scrolling through supplier websites on google, she stumbled upon ‌ChengRui‌, a Chinese manufacturer with a decade-long track record in fiberglass-based insulation products. What caught her eye were the detailed case studies showcasing projects in South America—something few competitors highlighted.

Intrigued, Ana sent an inquiry via ChengRui’s website, outlining her requirements: PVC Fiberglass sleeves, customized diameters (3mm to 25mm), and a minimum order quantity that wouldn’t strain her cash flow.

Within hours, Jessica, ChengRui’s sales manager, responded. She shared product certifications, including RoHS compliance and third-party test reports validating flame resistance up to 220°C. Unlike other suppliers, ChengRui offered free samples for quality verification. Ana tested the sleeves rigorously—exposing them to extreme heat and mechanical stress, and was impressed by their durability. The fiberglass weaving was tighter than her previous Brazilian supplier’s, reducing fraying during installation.

Price negotiations followed. ChengRui’s quotes were 25%, lower than Ana’s domestic options, even after accounting for shipping and tariffs. Bulk orders unlocked additional discounts, and ChengRui agreed to staggered deliveries to accommodate her warehouse space limitations. Ana also appreciated the flexibility in payment terms, which eased her initial concerns about overseas transactions.

Logistics posed a challenge initially. ChengRui’s team proposed a solution: shipping partial orders via air freight for urgent client needs while consolidating larger shipments by sea to cut costs. They partnered with a Brazilian customs broker to streamline import clearance, reducing Ana’s average lead time from 50 days to 28 days.

Within six months, Insul Tech Brasil transitioned 80% ,of its PVC sleeving procurement to ChengRui. Ana’s clients noticed the improvement—one automotive parts maker reported a 15%, drop in assembly-line defects due to the sleeves’ consistent insulation performance. This reliability helped Ana secure a contract with a major solar inverter manufacturer in Bahia, expanding her reach into Brazil’s booming renewable energy sector.

Today, Ana credits ChengRui’s responsiveness and technical expertise for revitalizing her business. “They treated me like a partner, not just another order,” she says. “Their team even helped me redesign product labels to meet Brazil’s updated safety regulations.” With ChengRui’s support, Insul Tech Brasil now plans to launch a line of flame-retardant cable wraps, targeting commercial construction projects ahead of the FIFA World Cup infrastructure push.

For Brazilian importers navigating supply chain complexities, ChengRui proves that innovation and affordability aren’t mutually exclusive, and that the right supplier can turn logistical headaches into lasting growth.
