Why do only some items have an Safety Data Sheet or ( MSDS) applied ?

OSHA has established Standards for Hazards Communication, which requires chemical manufacturers and importers to develop a Safety Data Sheet (SDS) for every hazardous chemical they produce or import.

For most American Hakko products, there are no chemicals contained in the products that would warrant the development of an SDS.  Where the product does contain any chemical that has the potential to produce any hazard, an SDS is available on request.
