Item unit of measure codes are used in international trade as adopted by the ECB Working party on Facilitation of International Trade Procedures in Recommendation No. 20 (March 1985). These codes are intended for use in manual and automated systems for the exchange of information between participants in international trade.
The asterisk after the unit name indicates recommended units of measurement that are either an SI (International System of Units) unit, or its multiple or a non-SI unit that may be used together with the SI units and their multiples.
Use these values to populate the UnitOfMeasure property tag when processing Level III data.
