Why does your factory need an MSDS?
Factory audit checkpoint
Export textile, garment and footwear factories are audited on MSDS availability as a baseline requirement. Missing MSDS equals a non-conformance finding during third-party assessments.
Worker safety
An MSDS at the point of use enables supervisors and workers to respond correctly to spills, exposures and emergencies, reducing workplace accident risk.
