Drained used lead autobatteries buying concern

We are an enterprise in Vietnam looking for source to import drained used lead automobile batteries under I S R S code RAIN. The volume is not very big but frequent at 200-300 tons per month. We still stop at a number of sources when we get enough for demand. We will not check around after that and desire for long term and stable cooperation. Beside the price, decent terms and conditions will be much considered. Any seller with unclear information of company and contact please do not raise contact. We will only proceed with clear and sound information profiles.

thanks and best regards,
Gary Nguyen
