I read an english version document, and there's some words i dont quite understand (since english is not my main language), especially the "on an exceptional basis" part, can you help me guys? Thanks before.
the full paragraph is:
A substance tracked for information purposes only, upon decision by the GASG Steering Committee. After discussion at the GASG Steering Committee and on an exceptional basis, an automobile manufacturer may include an individual substance or family of substances on the list under this (FI) reason code.
