Hello. This is MDSKorea.



Overview 

In this newsletter, we briefly summarize frequently asked questions(FAQs) regarding IMDS for practitioners, along with recent updates(IMDS Vehicle Manufacturers' Position and Privacy Statement).


  • IMDS: An international system for registering and reporting the substances contained in automotive parts and materials.

  • MDS: Material Data Sheet, a document containing information on the substances in parts and materials, submitted to clients via IMDS.




Key Content

Q1. Who needs to submit an MDS? 

If your company's product is used to manufacture automotive parts (components/semi-components), you are expected to submit an MDS to the direct customer purchasing the product. 

This applies to any company supplying parts or materials anywhere within the automotive supply chain.



Q2. Is PPAP documentation not required if it isn't specified in the contract? 

That is not the case. Even if it is not explicitly stated in the commercial contract, PPAP1) documentation may still be requested depending on customer or program requirements.

1) Approval documentation confirming whether a part is approved for mass production



Q3. Why is it important to prepare this thoroughly? 

This is because your customers also need to receive your MDS and related documents to continue reporting to their own customers. 

It is also utilized for responding to customer requirements and quality management systems (such as IATF 169492)). 

For this reason, the IMDS Steering Committee3) has requested suppliers to carefully prepare the MDS and necessary documents.

2) Automotive industry quality management standard

3) A governing body composed of major vehicle manufacturers (OEMs) that determines IMDS operational policies and data entry standards



Q4. Who is responsible when entering a contact person's email in the MDS? 

When entering a contact person's name and email in the MDS, the responsibility lies with your company. 

As a general rule, the differences by email type are as follows:


  • Department generic email: As it cannot identify a specific individual, no personal data-related responsibilities arise; however, only basic functions in IMDS are available.

  • Contact person's individual email: All functions of IMDS can be used, but the responsibility for managing this personal data is assigned to the company.


*Regardless of the type of email registered, the ultimate responsibility for the accuracy of the data submitted to IMDS and compliance with the terms of use always remains with the company.
