Ink Components Hazard Classifications

Recommended Health Hazard Classifications for Printing Ink Components
OSHA Hazard Communication Standards 29 CFR 1910.1200

Impact on US Printing Inks
The Safety Data Sheets (SDS) created for printing inks (mixtures) are almost solely developed using raw material supplier classifications and mixture classification rules (e.g. concentration cut-off’s, etc.). The health hazard classification of a mixture can differ when the component raw material has been misclassified or classified under a GHS version or implementation that is different than OSHA HazCom health hazard classification specified in Appendix A of the OSHA HazCom standard.

OSHA adopted the Globally Harmonized System for Classification and Labeling of Chemical (GHS) in 2012 aligning the Hazard Communication (HazCom) Standard (29CFR 1910.1200) with the GHS. The largest impacts of the HazCom/GHS “alignment” were the revisions to appendices A (health hazards) and B (physical hazards) of the standard.The changes that were made (this was not a complete adoption of the GHS) were based on the current (at the time) version of the GHS (i.e. Version III). GHS is revised frequently. As of 2018 the most current GHS is version VII. The OSHA HazCom standard does not change when the GHS is revised.

Classification of chemicals using the OSHA HazCom standard under Appendices A and B may not be consistent with the version of GHS in use in other geographic regions.

Assisting US Printers
To provide clarity and eliminate confusion in the customer base (i.e. printers) the NAPIM SDS Evaulation committee has undertaken a program aimed at identifying printing ink raw materials which are known to have health hazard classifications which are inconsistent with the health hazard classification procedure specified in Appendix A of the HazCom standard. These materials along with their recommended health hazard classification are listed below. This applies to printing inks sold in the US only.

This page, managed by the NAPIM Safety Data Sheet Evaluation Committee, is intended to assist the ink manufacturer in selecting the consensus classification for a number of commonly used raw materials. The NAPIM SDS classification committee will collect and aggregate ink raw material SDS's and list the classifications in tabular form (see below). Each listing represents a different raw material supplier classification. Please note that this non-inclusive listing represents only the SDS's submitted to the committee. The listing will be updated as new information is received. Any legitimate printing ink raw material SDS will be listed.
If you have any questions, comments or would like to submit a safety data sheet for inclusion on the listing please contact the NAPIM office.

Printing Ink Health Hazard Classifications for Mixtures

Printing inks are mixtures. The health hazard classfication of a mixture can be calculated (using concentration cut-off values of the designated health hazard) using the methods specified in Appendix A of the OSHA HazCom standard. The classification can be complex and confusing. The detailed, mixture classification requirements are described in OSHA's Hazard Classfication Guidance for Manufacturers, Importers and Employers . It is strongly recommended that an automated system (software-based) be used to determine the appropriate health and physical hazard(s).
