importance of drumming quality in trading Bitumen

I have written a lot about Bitumen quality, drumming importance and mixing bitumen with contaminants. today I received below email from a Bitumen buyer, which was affected by low quality drums. in this case it is not about the Bitumen quality, no contaminants, but bad packing.

(sorry for bad English, it is  exactly copied!)

Dear friend,
Please note that some traders and drummers are selling bitumen with a very low quality drums. The drums they produce are very poor and  frail . they sell the drum to buyers with same price that inform as IME for new steel drum and buyers don’t know until when open the containers in discharge port

Because a lot of water by the rain into barrels , This makes after placing the barrel in  containers , you will believe that drum is good and no leakages but after open container you will be see how much bitumen  Spilled on the floor of the container . when you want unloading the drums from containers you will be see With the slightest shaking, the barrel will be  leak  and begins to drain bitumen .  

this is ab-usage the name and reputation of the company also ab-usage of buyers trust .  I collected some of photos from Damaged buyers that you can see . please share the problem with all buyers in all website and group until we To prevent major fraud on the trade of bitumen in Iran.
