Quality control should not be a single inspection at the end. Build a multi-point QC plan: (1) raw material inspection before production starts, (2) first article inspection when the first unit comes off the line, (3) in-process inspection at 30% and 60% completion, (4) pre-shipment inspection when 80% is packed, (5) container loading supervision. Each step costs a fraction of catching defects at the destination.
Factory audits should cover five dimensions: (1) quality management system — do they have documented procedures and follow them? (2) production capability — can their equipment achieve your tolerances? (3) social compliance — are working conditions acceptable? (4) financial health — are they stable enough to complete your order? (5) export experience — have they shipped similar products to your market? A one-day audit can assess all five with a proper checklist.
Total landed cost is the only number that matters when comparing Chinese suppliers. It includes: factory price, inland freight to port, export customs fees, ocean/air freight, insurance, import duties, VAT, customs brokerage, and inland freight from destination port. A $10 product FOB can easily become $14-16 landed. Most first-time importers forget at least three cost components and end up with negative margins.
