FAQs
What is the difference between USP and NF?
Both are in the combined USP–NF. Drug substance monographs are generally in the USP. Excipient monographs are generally in the NF.
Is USP grade the same as a USP Reference Standard?
No. USP grade material complies with a monograph. USP Reference Standards are official materials issued by USP for use in compendial tests.
Does USP grade guarantee FDA acceptance?
No. Monograph compliance is expected, but FDA acceptance also depends on manufacturer GMP status, regulatory filings and the buyer's supplier qualification.
