To maintain profitability, calculate the Landed Cost rather than just the unit price. This includes factory-gate price, export duties, ocean freight, import tariffs, and last-mile delivery. Aim for a Minimum Order Quantity (MOQ) that allows for Full Container Load (FCL) shipping, which can reduce per-unit logistics costs by 20-40% compared to Less than Container Load (LCL). Additionally, prioritize suppliers on Made-in-China.com who offer OEM packaging (e.g., PDQ display boxes) to reduce your labor costs at the retail level.
