As per the United States Food and Drug Administration (USFDA), a import alert 66-40 is named as "Detention without physical examination of drugs from firms which have not met drug GMPs."
This alert is issued by the US health regulator when an inspection has revealed that a firm is not operating in conformity with current good manufacturing practises (GMP's).
"Detention without physical examination of drugs of such firms remains in effect until such time as FDA is satisfied that the appearance of a violation has been removed, either by re-inspection or submission of appropriate documentation to the responsible FDA Centre," the FDA said om its website.
