How a Ukrainian Trader Solved Supply Chain Challenges with Chengrui’s Insulation Crepe Paper

For over a decade, Mykhailo Kovalenko, a Kyiv-based electrical insulation materials trader, had struggled with inconsistent quality and delayed deliveries from European suppliers. His company, Volta Insulation Solutions, specialized in supplying crepe paper for transformers and motors across Ukraine. However, rising costs and logistical bottlenecks in Europe pushed him to explore alternatives.

The Pain Points

Mykhailo’s clients—local manufacturers of electrical equipment demanded insulation crepe paper with precise thickness (0.05–0.13mm) and high tensile strength (≥8kN/m). His previous suppliers failed to meet these specs consistently, leading to rejected shipments.        What is worse, prices had surged by 20%, after the pandemic due to energy crises in Europe. "We needed a reliable partner who wouldn’t compromise on quality or timelines," he recalled.

Turning to China

In 2023, Mykhailo attended an industry expo in Warsaw, where he discovered Chengrui, a Chinese manufacturer with IEC 60371-certified insulation crepe paper. Intrigued by their samples’ uniformity and competitive pricing (30%, lower than European quotes), he initiated contact. Chengrui’s sales team responded within hours, offering free lab reports and a flexible MOQ for trial orders.

Why Chengrui Stood Out

1.      Cost Efficiency: Chengrui’s vertically integrated production—from pulp processing to creping eliminated middlemen markups.

2.      Quality Assurance: Their electrical insulation paper exceeded DIN 7735 standards, with ±0.01mm thickness tolerance and oil-resistant treatments.

3.      Logistics Ease: Chengrui partnered with Ukrainian freight forwarders to deliver goods via Gdansk port within 35 days, avoiding EU customs delays.

The Result

After a trial order for electrical insulation crepe paper, Mykhailo’s clients reported zero defects—a first in his career. By 2024, Chengrui became Volta’s primary supplier, cutting procurement costs by 18%, and boosting customer retention.

"The consistency is unmatched," Mykhailo noted. "Even during China’s Lunar New Year, Chengrui pre-stocked inventory to ensure no disruptions." Today, Volta Insulation Solutions has expanded into Moldova and Romania, with Chengrui supporting just-in-time deliveries for 120+ metric tons annually. Mykhailo’s story underscores how strategic sourcing from China can transform regional trade hurdles into growth opportunities.
