For large volumes, Sea Freight (FCL or LCL) is the most economical choice, though it requires a longer lead time (30-45 days). If you need faster turnover, Rail Freight (for Eurasia) offers a middle ground. To reduce costs, ask the supplier to optimize packaging (e.g., shipping shoes in polybags instead of boxes to reduce volumetric weight, or shipping boxes flat-packed). Always clarify the Incoterms; FOB (Free On Board) is generally preferred for B2B buyers as it allows for better control over shipping costs and logistics providers.
