Geographic Restrictions
Introduction
US Export Administration regulates pumps that can be used in manufacture of chemical or biological weapons
ECCN 2B350 regulates sales of sealless fluoropolymer pumps (and parts) with flow rate >2.6 gpm to about 200 Countries
Exporting to any of these countries without an export license is illegal and can result in fines and imprisonment. For list, see
Export license is possible, but it requires registration of end user’s name and address
Size 02 and 05 are below the gpm limit and are therefore exempt.
