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.
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.
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.
