what does ssm stand for?

SSM is an abbreviation for the second stage of manufacture.

SSM only applies to new vehicles that have not yet been registered.

Manufacturers apply, test and meet all conditions put to them by the Department of Infrastructure, Regional Development and Cities. All ADRs (Australian Design Rules) must be adhered to. SSM approvals do not affect state and territory jurisdictional requirements. 

For example, Toyota Australia imports the Landcruiser as the first stage manufacturer. It meets all Australian design rule criteria.

A Marks 4wd portal axle system is then installed to the landcruiser pre-registration. We then apply to the department for the new VIN plate under our SSM approval. The department then issues the VIN plate after all quality control obligations have been met.

The vehicle is then recognised federally as having the equipment installed under the approval, and this is recorded on the Federal government database. The vehicle can then be registered in any state.

If you wanted to sell your vehicle then this process is very straight forward as it can be registered in any state due to the SSM fit-out.
