To optimize costs, buyers should analyze the Total Cost of Ownership (TCO) rather than just the unit price. This includes defect rates (which should be <0.3% for premium electronics) and packaging volume, as bulky retail packaging increases shipping costs. Seek suppliers on Made-in-China.com that offer tiered pricing, where moving from 500 to 2,000 units can often reduce the unit cost by 15-25%. Additionally, consider OEM/ODM customization costs for branding, which usually requires a higher MOQ of 1,000+ units.
