The IMDS (International Material Data System) is an active tool that aids all suppliers in

the automotive supply chain to register material data for all components (the materials

they are made from, and the basic substances those materials consist of) that are used in products produced for the automotive industry. Suppliers submit the material information for their products to their customers by interacting with the IMDS program by inputting the required data fields to name, describe, and classify the various levels of material in their product. Nexteer Automotive subscribes to the Global Automotive Declarable Substance List (GADSL) and accepts material data sheets created following IMDS recommendations and the Nexteer Automotive guidelines in this document.

The intentions of these guidelines are as follows:

Help to create data that is useful and accurate for the recipient (Nexteer Automotive and its constituents).

Receive and maintain the data in a concise and clear manner.

Create data that will satisfy legal demands and help with the disassembly and recycling at the end of vehicle life.

IMDS submissions aid in the tracking of materials used in the auto industry. The legislation is changing regularly, and the submissions to IMDS help the supply chain in the automotive industry maintain the integrity of the legislation by preventing the use of hazardous/banned materials in components used in the automotive industry. IMDS aids the customer in the supply network to verify the contents of their purchased parts before and during the part approval process. The Production Part Approval Process (PPAP) requires IMDS submission for each part number before PPAP approval can be granted to the supplier. Any changes to the part that affect material content requires a resubmission to IMDS for the new Rev level of the part or for the new part number associated with the part change.

Per the End-of-Life Vehicle (ELV) Directive, vehicles become scrap at a predetermined age. If the contents of the vehicle are to be recycled or disposed of in an environmentally friendly manner, the contents have to be identifiable for recycling based on cost, ecology and technical possibility; or disposed of in a manner that is non-hazardous to mankind and the environment.

The objective of this document is to provide Nexteer Automotive’s suppliers with supporting instructions and clarification for IMDS reporting per the SSSC 23000000 specification. For further IMDS training information go to www.mdsystem.com, select the IMDS Public Pages, and select Frequently Asked Questions (FAQ). Each of the frequently asked questions leads to a training module related to that topic. More information on FAQ’s is contained in the Appendix of this document.

To register a company, go to the IMDS public pages, select the contact button, and follow the online registration hyperlink (Online registration). Complete all required fields that are located in the online registration form and IMDS will provide a Company IMDS ID. It is important to note that your company may already be registered. Please contact the appropriate IMDS help desk for your geographic region to determine if your company already has one or more company IDs, the company Client Manager and contact information. If your company is already registered, you will be directed to your company’s IMDS client manager to establish an IMDS ID, if needed, within your existing company ID.

Suppliers must define all materials in the product supplied to Nexteer Automotive. All materials must be defined and identified prior to creating the product tree structure. One possible method is to use the product bill of materials (BOM) and create an outline of the product. The outline will also help develop the “tree structure” that will be part of the product IMDS submission.

Consider the following outline formats:

–  –  –

The component is the final salable assembly; it can be composed of subcomponents, their materials and basic substances, or one material and its basic substances, or any combination in between. The first step is to break the BOM into the appropriate groupings – determine the subcomponents, the material(s) each is composed of, and the basic substances that compose each material. Determining this “structure” for the component serves two purposes – first it organizes the content that can be pulled from existing data in the supplier system versus that which must be created by the supplier in IMDS, and second the exploded content picture makes for a good “checklist” to make sure all substances are included in the submission tree. With the continuing changes in what is considered hazardous, each basic substance must be accounted for because of future ramifications. Examples of material tree structures are available in the Appendix under the sub-heading Tree Structure Development Nexteer Automotive expects our suppliers to understand and utilize the IMDS recommendations that the IMDS Steering Committee OEM members have approved.

Material Definition Rev: 006 Page 5 of 31 14Oc09 / D. Jahn The IMDS Steering Committee has published several recommendations for defining materials for creating Material Data Sheets (MDS). In these recommendations, the guidelines for MDSs in different material categories are defined. The IMDS recommendations can be found on the MENU screen under Recommendations in the left navigation menu. Use the right scroll bar to reach each Recommendation title and view the contents.

Note: IMDS 002 was updated 2/15/2007 eliminating the use of the “Flat BOM” reporting except in certain identified components as noted in the IMDS recommendations (example: IMDS 019).

IMDS 001

IMDS 001 is the general recommendation for the requirements for MDS creation. Each succeeding recommendation is expansion of the general recommendation for specific material applications. Each recommendation expands the IMDS requirements in relation to that specific material category, and where applicable, gives guidance through the


Definition of those items that fall into the particular recommendation.

Where applicable the ranges and tolerances for the pure substances that are not part of the IMDS publications.

Example tree structures appropriate to the material within the recommendation.

Example searches in IMDS, synonyms for the material, and miscellaneous information that can expand the material topic.

This information can be useful for developing the information for the tree structure for the material and its basic substances.

Data Sheet Definition Every component, subcomponent, semi-component or material has its own MDS (Material Data Sheet). Each data sheet is built for the specific item and the material it is composed of.

–  –  –

MDS Number In creating any data sheet in IMDS, a unique number is generated by the system and assigned to that data sheet. This unique number identifies the specific data sheet, and can be used for finding the data sheet in IMDS. Each data sheet, though unique in itself, can be used in the creation of another MDS for a higher level component, or another component with the same content in different weights or percentages.

Tree Structure

Rev: 006 Page 8 of 31 14Oc09 / D. Jahn When creating a MDS in IMDS the left hand side of the page contains the material tree for the MDS. The components, subcomponents, semi-components, materials and basic substances that compose the main component of the MDS have to be inserted into the data sheet by adding the information into the material tree that is part of the MDS. The tree structure is like the outline suggested earlier in this guideline. Each level of the tree matches each level of the outline, and each level is characterized by a symbol / name combination. Each of these symbol / name combinations equates to a MDS that was created and then added to the tree for the main component. The symbol identifies the

type of item in the tree, and is defined as follows:

Components / Subcomponents:

A component is a complete assembly or a component within an assembly that represents a completed part. A component must have at least one material, one semi-component or one component/sub-component attached to it. When breaking down a complete assembly, the subcomponents that make up the assembly should be signified with this symbol not that of a semi-component.


A semi-component is not the same thing as a sub-component within a part. It is a semifinished product, e.g. steel coil, pipe, leather hide, which will go through further process steps to make a finished component. A semi-component must have at least one material or one semi-component associated with it. IMDS recommendation 001 covers semicomponents in more detail.


A material normally consists of basic substances only. The total of all basic substances must be 100%. There are exceptions in which a material consists of other materials – this is covered in IMDS recommendation 001. A material must be described in the state which it has in the finished component.

Basic Substances:

Rev: 006 Page 9 of 31 14Oc09 / D. Jahn A basic substance is part of a material. They must be chosen from the existing list in the IMDS. They must be entered in the form it exists in the material. The total must be 100% (or over 100% if ranges are used). They must be associated with the most specific CAS-number (Chemical


Services number assigned by the American Chemical Society).

More detailed information is available in the IMDS Recommendations. Some example tree structures of what is valid for a structure and what is unacceptable are available in the Appendix under the sub-heading Tree Structure Development Detail Page Every component, subcomponent, semi-component or material has its own MDS. When creating a MDS, specific data related to the item must be entered into the data fields of the detail page. This information is unique to the item, and in turn is unique to the item(s) that utilize these data sheets in creating the overall component. Some of the information is “auto-generated” by the IMDS program; the rest must be manually entered.

Each detail page has fields for the following information.


ID numbers / Version numbers, are automatically generated by the system when a new component/subcomponent/material is created. With this number the item can be clearly identified, and can be retrieved in the system when needed for addition to a tree or for modification.

MDS Supplier:

Auto-generated - filled in with the name of the MDS creating company.


The material name should always define the material and not be generic. The material name shall be chosen from existing standards, e.g.

A good source for material information is the Google search engine or MatWeb (see Appendix).

The ISO specification pages are available for purchase on the internet as well.

Rev: 006 Page 10 of 31 14Oc09 / D. Jahn

Trade name:

Product trade name - for standard products which are defined in public norms (e.g. most metallic materials), this entry is not mandatory. In drawings these trade names are sometimes predefined. Then the entry is mandatory. For materials which are not defined in public norms (e.g.

plastic materials, oils, fats, flake layers, glue etc.) this entry is not mandatory but useful in order to uniquely identify the product. The mandatory disclosure of materials and contained substances is not affected by the reporting of a trade name.


For metallic materials (Classification 1 - 4), for which a material number is defined in public norms, this entry is mandatory. For other materials it is optional or even impossible (e.g.

thermoplastics filled/unfilled or elastomers), because in some cases no material numbers are defined. (see Appendix)


Mandatory for thermoplastics (filled/unfilled, ISO 1043 1 - 4, see Recommendation IMDS 010), thermoplastic elastomers (ISO 18064, see Recommendation 013), and elastomers (ISO 1629, see Recommendation IMDS 003).


Mandatory - All materials have to be assigned a correct classification.


Public norms, in which material compositions are defined (e.g. EN, DIN, JIS, ASTM, ISO etc.).

For materials described in these norms an entry is mandatory. Nexteer Automotive requires norm/standard information for plastics (ISO 1043 – 1 thru 4 -see IMDS recommendation 010) based on the type of plastic; elastomers (see IMDS 003), thermoplastic elastomers (see IMDS 013), and metallic’s (use the ASTM, JIS or ISO classification for the specific material). Some examples were listed under the “Name” on the previous page.
