[MW:3873] Product Marking of Studs from supplier, SA 193 & SA 962.

Dear All,
 
I have an issue with respect the marking on the Stud as detailed below:
 
Issue: A trading company had provided the studs (SA 193 Gr.B7) of required sizes by cutting it from a long stud bars procured  from the studs manufacturer which caused the removal of original product marking and trade mark..
 
Statement in ASME Sec.IIA , SA 962, Clause 20.5:
 
" When product is altered in a manner which changes specified requirement (in my case it's length), it is the responsibility of the current certifying organization to ensure that the product marking is appropriately revised. This includes the removal of the name or symbol of the previous certifying organisation."
 
Present condition: The studs are supplied with only "B7" Marking and the trader had informed us that marking is done by them after cutting it to the required length. Also, trader had provided us the MTC from original manufacturer.
 
Additional Documentation asked by us: We had asked the trader to provide a certification letter stating that the studs are of xx heat no's and are from xx manufacturer (attaching original manufacturer MTC.
 
Confirmation required: With the above documentation work and product marking, studs can be accepted?
 
Thanks in advance
 
Ajay
