Demurrage and detention charges have become a significant cost factor. Demurrage is charged when cargo stays in the terminal beyond the free period. Detention is charged when containers stay outside the terminal beyond the free period. Free periods vary by carrier and route — typically 3-7 days for demurrage and 5-10 days for detention. Always confirm these terms in your booking. Track your container return dates religiously.
Sea freight from China to major global destinations typically takes 25-35 days for the US West Coast, 35-45 days for the US East Coast, 30-40 days for Northern Europe, and 20-30 days for the Middle East. These are transit times only and don't include loading, unloading, or customs clearance. Always add 7-14 days to the transit time when quoting delivery dates to your customers. Buffer time is not waste — it's risk management.
Container loading optimization can reduce your per-unit shipping cost by 5-15%. Key factors: product dimensions, packaging design, loading pattern, and container type. Mixed-size products often achieve higher container utilization than uniform boxes. Request a loading plan from your forwarder before finalizing packaging. Small changes in box dimensions can significantly improve container fit. This is free money — most importers leave it on the table.
Your freight forwarder selection is one of the most important decisions in your supply chain. A good forwarder offers: competitive rates (not the cheapest), transparent pricing, proactive communication, customs expertise, and problem-solving capability. Interview at least 3 forwarders. Check their references. Start with a trial shipment before committing to a long-term relationship. A bad forwarder can cost you more in delays and damage than you save on freight.
