Why Certifications Matter in Intimate Apparel Manufacturing?
At Gyknit, we understand that premium custom panties and seamless underwear require more than just skilled craftsmanship—they demand rigorous quality control, ethical production, and scientific material testing. As a leading Chinese lingerie manufacturer, we hold 12+ international certifications that validate our commitment to excellence.
What It Means
OEKO-TEX® tests for 300+ harmful substances, including:
