3.Is the item in stock or need to be purchased from another supplier?
We have a large inventory of goods and have our own warehouse.
4.What advantages do we have over other suppliers?
Our company has a large amount of inventory and a number of warehouses, but also in the country's important industrial provinces and cities with offices and a number of overseas service points. To provide you with intelligent manufacturing one-stop comprehensive services, save efforts, labor and cost.
5.Can you provide 100% new original authentic products?
We only sell new original genuine, no renovation, no fake, only for the original factory original!
6.How long is the delivery time?
If there is a stock, it will take 2-3 working days to ship, if the quantity is large, it will take 5-7 working days after receiving the payment, if it is not a conventional model, it will take some time, we will inform you of the specific delivery time.
7.Is there technical support available?
Of course, we have a professional technical team that can help you solve technical problems.
8.How do we guarantee quality?
We have three processes to control the quality of goods.
1). Our engineers will inspect the production and quality control in the factory regularly.
2) Incoming materials shall be inspected by experienced purchasing engineers before they can be stored.
3). At least 2 people in the logistics department cross-check the goods to be sent before delivery.
9.Can you guarantee the safe and reliable delivery of your products?
Yes, we strictly adopt the international standard packing. We also use special packaging for dangerous goods, and refrigerated shipping for items with temperature requirements. Special item packaging and general cargo standard packaging requirements may incur additional costs.
