Your top SDS questions and how GHS ties in
Webcasts don’t always allow time for us to answer all the great questions our customers ask or to answer them as thoroughly as we’d like. Two Safety Data Sheet (SDS) questions were asked in recent hazard communication (HazCom) webcasts that I’d like to expand upon. The first is whether Section 1 of the SDS must contain a U.S. address. Second is why SDSs from countries outside the U.S. may classify a hazardous chemical differently than what’s seen on an SDS that originated in the U.S.
Section 1 contact information
Does Section 1 of an SDS require a U.S. address? Yes! (That’s the short answer.) OSHA says in a letter of interpretation: “Section 1 of the SDS must include the name, address, and telephone number of the manufacturer, importer, or other responsible party. Section 1 must also include an emergency phone number. The address must be in the United States, and the phone number must be a domestic number. If a manufacturer, importer, distributor, or employer chooses to add a foreign address (non-U.S. based) to an SDS, it may be listed in Section 1 if the responsible party believes they may be able to provide additional supplemental information and is done in a fashion that does not cause confusion.”
When chemicals are imported into the U.S., the person (meaning one or more individuals, partnerships, associations, corporations, business trusts, legal representatives, or any organized group of persons) who imported the product automatically becomes the responsible party. As such, they assume the responsibility to ensure it’s compliant with OSHA’s HazCom Standard, including classifying the chemical and developing or obtaining an SDS.
SDSs from outside the U.S., but first, a little history
Didn’t the GHS harmonize hazard communication? Shouldn’t a chemical’s hazards be classified the same, regardless of where the SDS originates? The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) is an effort to create a world-wide, universal chemical hazard communication and container labeling system. It provides standardized definitions for chemical hazards, addresses classification of chemicals by types of hazard, and proposes standardized hazard communication elements, including labels and SDSs. The first edition of the GHS was published in 2003. It’s updated and revised every two years and is now in its tenth edition (2023). In 2012, OSHA aligned its HazCom Standard with the GHS 3rd edition (published in 2009). OSHA intends to align its current HazCom Standard with the 7th edition (published in 2017) of GHS; a final rule is expected in early 2024.
The GHS is not a standard and does not impose requirements on countries that adopt it, such as a trade agreement would. Instead, it’s a voluntary set of “building blocks” which each country can adopt as it sees fit. For countries that do not have existing chemical hazard systems and may not have the resources to develop and maintain one, the availability of a globally harmonized approach allows them to provide necessary protections for their citizens while enabling them to participate in international trade.
While an SDS must always follow the specified 16-section format, because various editions of the GHS (or parts of those editions) have been adopted in the U.S. and internationally, you may see discrepancies in SDSs regarding how chemicals are classified.
Key to remember: SDSs used in the U.S. must contain domestic contact information in Section 1. Discrepancies in chemical classification may arise in SDSs outside the U.S., depending on which version of GHS was adopted.
