Frequently Asked Questions

What causes international shipping delays?
Common causes include production slippage, port congestion, customs holds, incomplete documentation, peak-season capacity shortages, weather, and disruptions such as canal or port closures.
How can I avoid shipping delays from China?
Build buffer time into schedules, order early before Chinese holidays, complete documentation accurately, inspect before shipment, and track shipments proactively to react to issues early.
How do Chinese holidays affect shipping?
Chinese New Year and Golden Week cause factory closures and capacity shortages before and after, which can delay both production and shipping. Order well ahead of these periods.
