Ensure freight charges align with actual package weight to avoid overpayment.

Accurate freight cost calculation is fundamental for maintaining healthy profit margins in cross-border e-commerce. A common pitfall leading to financial drain is overpaying shipping fees due to discrepancies between estimated and actual product weights. The CNFANS Spreadsheet provides a systematic solution for tracking product weight adjustments, empowering you to take control of your logistics spend.

This "weight drift"—even by a few hundred grams—compounds across multiple orders and shipments, resulting in significant, silent overpayment to freight forwarders.
