HazCom2012(GHS) provides the capability to utilize one Safety Data Sheet (SDS) for a range of ink formulations.
excerpt …The concentration (exact percentages) of each ingredient must be specified except concentration ranges may be used in the following situations:
- A trade secret claim is made
- There is batch-to-batch variation, or
- The SDS is used for a group of substantially similar mixtures
CFR 1910.1200 App. D
excerpt…(b) The concentration (exact percentage) shall be specified unless a trade secret claim is made in accordance with paragraph (i) of §1910.1200 when there is batch-to-batch variability in the production of a mixture, or for a group of substantially similar mixtures (See A.0.5.1.2) with similar chemical composition. In these cases, concentration ranges may be used.
Appendix A TO §1910.1200—Health Hazard Criteria (Mandatory)
A.0.5.1.2 Batching
For mixtures classified in accordance with A.1 through A.10 of this Appendix, the toxicity of a tested production batch of a mixture can be assumed to be substantially equivalent to that of another untested production batch of the same mixture, when produced by or under the control of the same chemical manufacturer, unless there is reason to believe there is significant variation such that the toxicity of the untested batch has changed. If the latter occurs, a new classification is necessary.
Substantially similar term defined in Compliance Interpretation Letter
excerpt…Substantially similar”…is one that has a similar starting material, production process, and range of physicochemical properties (e.g., boiling point and carbon number) and similar constituent compositions…
