If a common sample is needed, we shall not charge for the sample fee. But the delivery cost shall be paid by the client. If more than three individual samples are needed, the client needs to pay the sample fee. Besides, if the sample of new product is needed, the sample fee shall be paid. To avoid the waste of sample, if a client is not satisfied with the sample upon receipt, please return the sample and we shall also return the sample fee. But the delivery cost shall be paid by the client. We can post the returned sample to other company in need, which we hope can be understood by our client.
