4. FAQs: IMDS common matters
“Hidden” and “Deleted” Substances
Substances in IMDS may be marked as hidden or deleted for various reasons, including prevention of duplicate data, standardization of substance names, and data correction.
When using existing data, if hidden or deleted substances are included, they must be replaced with alternative substances prior to submission.
Process Chemicals
Process chemicals are substances that do not remain in the final product.
They may be present as impurities up to 0.1%; however, approval will not be granted if this threshold is exceeded.
(* Actual residual presence must be verified.)
Confidential Substances
If disclosure is difficult due to trade secrets or similar reasons, substances may be marked as confidential up to 10% per homogeneous material.
Substances that are declarable or prohibited under GADSL, SVHCs, or substances requiring an application code cannot be treated as confidential.
If the confidential portion exceeds 10%, the Hyundai/Kia IMDS staff needs to be designated as a trust user.
Substance Range Criteria
The criteria specified in Guideline 001 must be followed.
Example: If the minimum range value is 5%, and the maximum allowable tolerance is 3%, the acceptable range is limited to 5–8%.
