What to check before you buy NAC in bulk — specification, grade, regulatory filings and supply reliability.
NAC is supplied as pharmaceutical (API) and food grade. The API grade meets ChP / USP / EP, while the food grade meets FCC / AJI. Tell your supplier which pharmacopoeia edition your market requires — this determines the assay method and the limits applied.
For EU and regulated markets, verify that your supplier holds the documents your registration dossier needs: DMF (ChP / USP / EP), a Written Confirmation (WC) for the EU, COPP, GMP certificate and stability data. Missing filings can delay your own market approval.
Look for GMP-compliant manufacturing, full batch traceability and release against current pharmacopoeia limits. Our production site passed a zero-deficiency ANVISA (Brazil) inspection, and NAC is produced in a sealed pipeline with 12,700 DCS control points.
