•FAQ
Q 1. what's the payment terms?
A. We accept LC, T/T, D/P,Western Union PayPal. If others, we can discuss.
Q 2. how's the delivery time ?
A. usually it will take about 30 days after order confirmed.
Q 3. tell me the standard of package?
A. For the small capacity, we will use carton, but for big capacity, we should use strong wooden case for protection.
Q 4.Could you offer Form A or C/O ?
A. No problem. We can prepare relative documents to origin affairs office or other office to apply for related certificates.
Q 5.Would you accept to use our logo ?
A.If good quantity, it absolute no problem to do OEM.
Q 6.We want to know month capacity.
A. It depends on which model.For example for relay type capacity , month capacity can reach near 5000pcs/month while big capacity near 2000pcs/month.
Q 7.Where is your market?
A. Our products are popular in North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, Mid East, Eastern Asia, Western European so on. Some of them are our regular customers and some of them are developing. We hope you can join us and make mutual benefit from our cooperation.
Q 8. what kind of certificates you have ?
A. Our company already achieve ISO9001, and for products, we have CE,ISO9001,SGS and so on.
