Registration Code

The registration code includes a letter prefix M (designating a manufacturer and/or exporter), K (designating a broker), followed by a four or five digit registration number (e.g. K-1234 or M 12345). The code is proprietary to the registrant and should be handled as such. It should not be shared with anyone outside the registrant entity.
