Surface cargo shipment, which includes transportation by road, rail, and sea, offers several advantages: 1. Cost-Effectiveness: Generally cheaper: Surface shipping, especially for large volumes and non-urgent goods, is often significantly more economical than air freight. Sea freight, in particular, offers the most affordable rates for long distances and bulky cargo. Scalable pricing: Road and rail transport can offer volume-based pricing, making them cost-effective for businesses dealing with large shipments. Reduced surcharges: Compared to air freight, surface transportation may have fewer surcharges and additional fees.
