As mandated by OSHA, we are working feverishly converting all of our MSDS (Material Safety Data Sheet) documents to the new GHS-compliant SDS (Safety Data Sheet) document format. As part of this effort, all SDS documents will soon be available for download here. We will no longer mail the documents with your Invoice, or include with shipments. This is in our attempt to furnish your SDS documents in the most efficient manner possible. If you require your SDS documents via another method, please call Customer Service at 800-242-7694 or send an email to firstname.lastname@example.org. Thank you.
