Form FDA 3602A contains a field for certification from a National Taxing Authority for a
foreign business or affiliate, which serves as authentication of the gross sales and receipts for
that business/affiliate. FDA expects you to obtain this official certification.
If the National Taxing Authority does not provide the certification, you may provide a
written explanation of impossibility for why you were unable to obtain this certification
along with Form FDA 3602A. All explanations should include documentation from the
National Taxing Authority, in English, of refusal to provide the certification. All
explanations are reviewed on a case-by-case basis.
