MARKING CLAUSE : Contractor/Manufacturer must inscribe/ engrave/ screen-print/ emboss vendor's name/identification marks as well as month and year of manufacture on item supplied to East Central Railway. The location of these identification marks should be such that they do not affect the functional utility and structural stability of the components/materials, and also do not get obliterated on wear and tear. For very small items where marking on individual item is not possible, the vendor will arrange to print Vendor's name/identification marks as well as month and year of manufacture on standard packing, after obtaining specific approval from the purchaser in each case. The decision of the purchaser on whether such approval is to be granted or not shall be final and binding.
