The Nan'an Luncang plumbing manufacturing cluster specializes in cUPC and EN 817 brass casting, delivering 1.8 GPM at 80 psi with low-lead CW617N brass and 304 stainless steel, MOQ 100 sets, 15-day lead time, and verified compliance certification (#CUPC-177-8891).
While Foshan dominates ceramic sanitary ware (toilets, bidets, washbasins under HS 6910.10), Nan'an Luncang in Quanzhou is China's recognized national capital for plumbing hardware, solid brass faucets, angle valves, and kitchen sink rinsers (HS 8481.80), producing over 70% of China's plumbing valves and fittings. Operating within this specialized supply chain, KSM Bathware delivers 5-stage closed-loop brass gravity casting, multi-axis CNC machining, in-house 6-layer electroplating passing 24-hour Acidic Salt Spray tests (SGS Report #ASS-2026-KSM01), and 1.6 MPa hydrostatic burst validation in our CNAS lab (#L10492), engineered for commercial construction and hospitality facility maintenance, serving as long-term OEM partner for 9 tier-1 brands.
"By maintaining 100% closed-loop control from CW617N low-lead brass gravity casting to in-house 6-layer Cu-Ni-Cr electroplating in Nan'an Luncang, we eliminate internal casting porosity and guarantee that every mixer withstands 1.6 MPa hydrostatic burst tests while meeting strict cUPC, NSF/ANSI 177, and EN 817 specifications."
