Guidelines for Outsourcing of Moulded Bodies a) Outsourcing of moulding facilities may be permitted with the following organizations (Moulder): For Domestic Manufacturers  Any dedicated moulding unit in the conforming/ authorized industrial area and located under the jurisdiction of the same Branch Office.  Any other unit of the Licensee/ Applicant or their sister concern, which is having a valid BIS licence for the same product under the jurisdiction of the same Branch Office. For Foreign Manufacturers  Any dedicated moulding unit in the conforming/ authorized industrial area and located in the same city where the applicant/ licensee is located. b) The dedicated moulder shall not carry out moulding for units other than the particular Applicant/ Licensee. c) The Manufacturer shall take the following actions:  Enter into an agreement with the moulder which shall comprise, interalia, the terms and conditions for moulding including the condition of dedicated moulding, period of agreement etc.  Declare the Items and Brands for which he intends to outsource moulding.  Declare the name, ownership details, address, details of the responsible person, phone

number, etc. of the moulder. d) It shall be the responsibility of the licensee (the firm which is outsourcing the moulding activity) to ensure that no finished material is produced or assembled at any place other than the licensed premises and he shall be responsible for any misuse of ISI mark at the moulder’s premises. An Undertaking to this effect shall be furnished to BIS. e) Records of raw material issued date-wise, moulded material received back date-wise and item-wise shall be maintained by the licensee. Similar records shall also be maintained by the moulder. f) The moulder shall ensure that there is a separate dedicated space for keeping moulded components as well as the raw materials received from the licensee. Colour coding of bins/ separate storage location etc. may be used to ensure easy and quick traceability. Appropriate records are to be maintained at both the units. g) The licensee shall ensure that there are adequate means of ensuring the quality of incoming outsourced moulded bodies. PM/ IS 1293/ 2/ January 2021 12 h) For applications received with request for outsourcing of moulding facilities, a special inspection of the

moulder’s premises shall be carried out to adjudge the capability of the moulder in addition to the preliminary inspection at the applicant’s premises. Special Inspection Charges and any other charges, as applicable, for this visit shall be collected from the applicant in advance. The process flow chart submitted by the applicant shall clearly indicate the outsourcing of moulded bodies. The recommendations for GoL shall include details on outsourcing of moulding operation by the firm. The details of outsourcing may also be included in the GoL intimation letter. i) For existing licensees who intend to outsource the moulding facility, the licensee shall submit a fresh process flow chart indicating the outsourcing of moulded bodies. The permission for outsourcing may be given to the licensee after complying with all the procedures including verification visit to the moulder’s premises. j) Whenever there is a change in the moulder, the licensee has to enter into a fresh agreement with the new moulding unit. The permission for outsourcing may be given to the licensee after complying with all

the procedures including verification visit to the moulder’s premises. k) During the operation of the licence, records required to be maintained at the licensee end with respect to outsourced moulding shall be verified during surveillance visit at the licensee’s premises by BIS Certification Officer. l) BIS Officer(s) shall have access to the moulder’s premises and if at any time the same is denied, permission for outsourcing shall be withdrawn. An undertaking in this respect shall be obtained. m) For Domestic manufacturers, the visit to moulder’s premises may be taken up as a special visit as and when needed. Special Inspection Charges for this visit shall be collected from the licensee after the visit. An undertaking from the licensee regarding payment of such charges shall be obtained. n) For Foreign manufacturers, BIS shall maintain surveillance over the moulder’s premises in addition to the manufacturer’s premises. Special inspection charges and all other applicable charges for this visit shall be payable by the licensee. Note:  The Indian Standard does not impose any restriction on the manner/ method of Marking so long as the

Durability clause is complied with. As such, the product may be marked with the Standard Mark, CM/L Number, Manufacturer’s Brand and other markings during the process of moulding itself, in which case all the conditions stated above shall apply.  However, if the Marking on the moulded bodies is done at the Licensee’s own premises by other means such as pad printing/ laser marking etc, the moulded component may be treated as any other bought out component/ raw material as these are not marked with the ISI Mark or CM/L Number during the outsourced moulding process. Notwithstanding this, the Applicant/ Licensee shall ensure that there are adequate means of ensuring the quality of the incoming components.
