1, Pay attention to low price and branded products. You need to be careful when a supplier provides low priced and branded products, especially in Computer and Consumer Electronic industrials. 2, Be aware of "Post" Delivery "Post" delivery is different from EMS or international express. It takes longer time to arrive the destination (more than 2-3 months). Take "China Post" for example, China Post could only accept small and light goods within 2kg. Here are the differences between China Post and EMS: The China Post tracking number will be RA*********CN or RR*********CN, but the EMS should be EE*********CN. 3, Be careful to products of Chemical, Metallurgy and Paper related industries When pay to the supplier Please make sure that the bank account of the supplier is correct. After payment,we suggest you: Check goods carefully before the supplier delivery it. You could hire an agent to help you if you cannot come to China in person. Inspect the goods before customs clearance after they arrive; it is necessary to confirm the packing marks are correct, and open package to inspect to goods at customs, then save the out-of-the-box inspection videos, photos. And save the weight report and test report which is issued by customs. That will be the most effective and important proof to protect your rights in the future. I hope it will be helpful to who want to do business with Chinese suppliers.
