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.
