From raw material selection to liner knitting, coating, and final inspection, SINCERE controls every parameter. Our deep involvement across the entire value chain continuously enhances our command over product quality.

While the industry relies on EN388, EN407, and other certifications as benchmarks, we set the bar higher. Every batch must pass our in-house lab tests for cut, puncture, abrasion, and oil resistance. Only when the results exceed standard requirements do we approve shipment.

Our facility is ISO 9001 certified and undergoes regular audits by BSCI, SGS, and TÜV on behalf of our clients. All equipment upgrades, QC reports, and shipping data remain fully traceable.

Product limits are defined by raw materials and machinery. We regularly upgrade our knitting and coating equipment while maintaining close partnerships with long-term, stable suppliers to ensure uncompromising product quality.
