Prohibition on trade with North Korea: customs clearance allowed only after correcting country data to prevent prohibited imports or exports. Customs officers must strictly enforce prohibitions on trade with North Korea by amending any Bill of Entry or Shipping Bill that incorrectly names DPRK/KP as Country of Origin or Destination; OOC/LEO or Customs clearance is to be granted only after deleting the incorrect DPRK reference and recording the correct country, with penal action possible for wrong declarations and prompt amendment required for bona fide data errors to prevent misleading publication of trade statistics.
