12-Node Order Production Tracking SOP, AQL 1.5 Inspection & P1/P2/P3 Warranty SLA
Full visibility from raw copper ingot smelting to Xiamen Port container sealing—backed by our 12-node visual tracking protocol, ISO 2859-1 AQL 1.5 pre-shipment gate, and P1/P2/P3 (24h/48h/72h) engineering claim resolution SLA.
Modules 19 and 20 of the BM Bathware Export Knowledge System govern post-PI execution and long-term after-sales reliability. Every container order at Quanzhou Baoming Sanitary Ware Co., Ltd. (BM Bathware) progresses through a documented 12-Node Production & QC Fulfillment SOP with timestamped photographic and video evidence delivered to the buyer's merchandising team: from Node 1 (PI & SMP-* Golden Sample Lock) and Node 2 (Raw Brass OES Spectrometry) through Node 5 (5-Axis CNC Machining), Node 7 (PVD / Electroplating XRF & 48h CASS Audit), Node 8 (100% 0.6 MPa Air + 1.6 MPa Water Pressure Testing), Node 10 (ISO 2859-1 AQL 1.5 Pre-Shipment Inspection), and Node 11 (Container Loading & Seal Supervision). Post-delivery support is governed by a 5-Year Commercial Warranty and a tiered P1 (24h), P2 (48h), and P3 (72h) 8D CAPA resolution SLA.
