Can you send us free samples?
Yes. Free samples are available upon your request, but the courier charge should not exceed 100$.
We have had stable cooperation with one courier agent in Shenzhen for many years. Their charges are much lower than these of courier companies, like FedEx, DHL, or UPS. We will choose the most cost-effective way to deliver free samples to your hands. Or you can tell us the favorable courier you need.
But if samples are chemical in powder shape, sorry that we can not provide them free of charge. Because it is not easy to send them. You need to offer us your courier account.
