They are also required to provide proper instructional documentation, safety documentation, and calibration documentation according to Title 21 which the seller is attempting to bypass. This vendor is in Hong Kong. For him to import the laser it must have an FDA accession number. So he's basically telling you he will ignore the FDA requirements after he gets it into the country.
