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.
The Bill of Lading is the single most important shipping document. It serves as: receipt of goods, contract of carriage, and document of title. Three main types: Original B/L (controllable — need signed copy to release cargo), Sea Waybill (non-negotiable — cargo releases automatically), and Telex Release (electronic — fastest but no physical document). Choose based on payment terms and trust level with the buyer. For L/C transactions, only Original B/L is acceptable.
Customs valuation is a common source of disputes. Chinese customs values goods for export based on the transaction value (the price actually paid). The importing country's customs may independently assess value. Common triggers for customs audits include: values significantly below similar goods, frequent changes in declared value, and incomplete documentation. Maintain consistent, well-documented valuation practices.
Cross-border e-commerce logistics from China has three tiers. Tier 1: express (DHL/FedEx/UPS) — 3-7 days, highest cost, best for high-value or urgent items. Tier 2: air freight — 7-15 days, moderate cost, best for mid-value items. Tier 3: sea freight — 25-45 days, lowest cost, best for high-volume items. The fastest-growing segment is tier 2.5: 'sea-express' services that combine sea freight with express final-mile delivery, offering 12-18 day delivery at near-sea freight prices.
