Q&A:
Q: What's your Payment terms?
A: We accept TT & Western Union for payment.
Q: How to order a sample?
A: You can contact us directly and tell us your requirements on any of our products.
Q: Could you print our company logo or design on the products?
A: Yes, we can accept your need but we will share the charge with you.
Q: If we decide to move forward with our order what is the next step?
A: You place an order first. Then we will send you PI. After you settle the payment by TT or the Western Union. We will arrange production for you.
Q: What is your normal production lead time for a first order and then for repeat orders?
A: It depends on the product you need. For example, if you purchased a 1550nm fiber circulator for your first order, and then you look for it again, but we will check the material of it and tell you the delivery time.
Q: Do you have warranty policy?
A: Yes, we have. We provide 12 months maintenance warranty.
