Classification of a Formulation on Formpak vs supplier SDS

There’s a difference in classification between a formulation I’ve entered onto Formpak compared to the supplier who supplied the SDS and composition- how do I know which is right?

As a general guide, if you have a difference between classifications this almost always means one or more of the following:

1. The ingredients are not the same
2. The ingredients don’t have the same hazards
3. The ingredients are present at different percentages. Particularly if you enter ingredients using the top amount in a band you are likely to obtain a different classification.

A good method to follow to ‘spot the difference’ is:

1. Look at the top level hazards in Section 2, which core hazard is missing? (e.g. you may be missing Aspiration Hazard Cat 1 H304)
2. Look at the list of components in Section 3. Are all the components the same and at the same percentage?
   
   2a) if there is a missing component, check your formulation. Is the component present in your version of the composition? If it’s present, does it have the same hazards?
   2b) if the components are different percentages this is a likely cause of classification difference.
3. Look at the classifications of the components, focus on the hazard which is missing (e.g. look for components with the H304 phrase on the supplier SDS and see if your components also have this hazard)
   3a) If you find a component has a different hazard from your supplier compared to the hazard you have on your system, then you need to make a judgement about which classification is correct.
