For bulk orders, Ro-Ro (Roll-on/Roll-off) shipping is generally the most cost-effective and safest method for vehicles. However, for smaller trucks or disassembled units (SKD/CKD), 40HC container shipping may be cheaper, provided the supplier has experience in professional container loading and lashing to prevent movement during transit. Always clarify Incoterms; CIF (Cost, Insurance, and Freight) is common, but FOB (Free On Board) gives the buyer more control over the shipping timeline and costs.
