Annexure 2 (Para6 refers)


1. Category –1. Items, for which complete ToT, i.e., Engineering and Manufacturing documentation to enable the Production Agency carry out fabrication, assembly and test of the item from CKD/IM Kit level as the case maybe, is being provided by the OEM, may be classified under the head “CToT”. 

2. Category –2. Items which are manufactured by the OEM‟s Subcontractors based on engineering documentation provided by the OEM and these Engineering Documentation are being provided by the OEM to the Production Agency, may also be classified under the head “CToT”. 

3. Category –3.

(a) Items in respect of which development and manufacture by the OEM has been subcontracted to its vendors/ sub-contractors based on only the procurement specifications provided by him and the OEM is not in a position to provide any additional technical information to the Production Agency except the procurement drawings/ specifications provided by him to his vendors/ subcontractors, may be classified under the head Single Vendor “Subcontract”. For the purpose of evaluating the depth of ToT, it will be presumed that the ToT in respect of these items for indigenous manufacture is not provided. OEM shall ensure authorization to its vendors/ sub-contractors to supply items, manufactured against OEM‟s specifications to the Production Agency against its purchase orders. 

(b) However in such case, the OEM in collaboration with his vendor/ subcontractor, is required to provide the Production Agency, maintenance Documentation, the recommended list of spares for repair and overhaul as may be applicable and maintenance training at the vendor‟s/subcontractor‟s premises, then such vendor items may be classified under the head „Limited ToT for maintenance support‟, i.e, “MToT”.

4. Category – 4. 

(a)  Items including catalogue/ standard items sourced by the OEM against his procurement specifications as „Fully Finished‟, may be classified as “Bought Out”. Evidently ToT for such items for indigenous manufacture will not be available and the OEM will be able to provide only the procurement drawings/ specifications, sources of supply. OEM has to ensure the availability of such items or its equivalents during the life cycle of the product. However, in respect of some of the selected items in this category, if the OEM, in collaboration with his vendor, is able to provide the Production Agency documentation for maintenance, recommended list of spares for repair and overhaul as may be applicable and maintenance training in the vendor‟s premises, then such items may also be classified under the head „limited ToT for maintenance support‟ i.e. “MToT”.

 (b) OEM shall ensure periodical review of obsolescence, study of the Bill of Items (BOIs) and provide a retrieval scheme for a minimum period of 40 years from the production of last unit under the present proposal.

5. Category –5. Some of the items for which the ownership of Design and Manufacturing Documentation is available with the OEM, but the OEM is not willing to transfer the technology to the Production Agency may be classified under the head „Proprietary‟ items. The list of such items shall be far and few and generally restricted to components/ processes specifically developed by the OEM for the licensed product. No item in the product structure which is critical either from the technology point of view or from the point of view of significant value addition or which constitutes a significant relative percentage of the product cost (say > 10%), will be acceptable under the head “Proprietary items”. Further, at any stage during the life cycle of the Product, if the OEM intends to discontinue the production of Proprietary items, the complete technical documentation in respect of these items available with the OEM or his subcontractors will be passed on to the Production Agency to enable indigenous manufacture or establish alternative routes of meeting the requirement. Also, a base price for such items with an escalation formula for future supplies shall be given for slab quantities by OEM.
