There is no report from our production for any damage drum but the Liner claim us for oil stain and charge the cleaning cost. At first we are doubt if this stain happened since before loaded but regarding to your confirm of inspecting & cleaning each container before load that it would not be.
Anyway would be helpful to us if you could check back/share us inspection sheet for this order. just to reconfirm that this stain occur during container been used in our shipment.
