NIT is for supply of Integrated Pre-Lubricated Cartridge, it does not detract from that product merely because certain specifications of the ingredients and components which go to make the same may differ. If the specifications are not followed, the Integrated Pre-Lubricated Cartridge can be rejected as a whole. We find it a little difficult to appreciate that if in the earlier NIT also, the product to be supplied was an Integrated Pre-Lubricated Cartridge and the specifications mentioned separate details of the individual components, and the NSIC store details submitted by the Petitioner mentioned those components, the Respondent found it acceptable, but even though, the NIT dated 23.7.2015 was for the same product not with different specifications of the components but only the final product how it becomes a different product completely and is required to be mentioned separately in the NSIC store details as being one of the tendered items.
