Choosing between ocean freight and air freight represents one of the most critical decisions for Bangladeshi businesses sourcing raw materials and consumer inventory from China.
1. Cost Comparison & Volume Economics
- Northern Logistics Sea Freight (LCL/FCL): Priced per Cubic Meter (CBM) or per ton. Ideal for bulk consignments exceeding 100 kg or 1 CBM. Per-unit transportation cost is dramatically lower—often 70% to 85% cheaper than air cargo.
- Northern Logistics Air Cargo: Priced per kilogram. Highly economical for urgent spare parts, lightweight electronic accessories, fashion apparel, and time-sensitive factory machinery components.
2. Transit Schedule & Timeline
- Sea Route: Approximately 35 to 40 days total door-to-door transit time. Vessels depart southern China ports (Ningbo, Shanghai, Shenzhen) sailing directly across the Bay of Bengal into Chittagong Port (CTG), followed by ICD de-stuffing and inland delivery with complete customs clearance.
- Air Route: Approximately 5 to 10 days door-to-door from China hub receipt to Dhaka client handover.
Recommended Strategy
Most experienced Bangladeshi retailers adopt a hybrid procurement model: ship 80% of bulk inventory via scheduled ocean container consignments to maximize gross profit margins, while dispatching 20% of fast-moving styles and critical stock via air cargo to prevent stockouts.
