Required when shipping a CPSC-flagged HTS code to the United States. Set DeclarationOption to 1 (Full Certificate of Conformity), 2 (CPSC Product Registry) or 3 (Exempt / Disclaimer). Option 1 is not available on USPS services.

Leave all CPSC fields blank if the commodity does not require a declaration.
