Special rules of classification

Japanese documents are very important and the Japanese documentation and classification has to be considered for search, especially for rice.

The Japanese FI-classes related to preparing grain for milling are B02B 1/00 - B02B 7/02&109. The corresponding F-term theme code is 4D043 that is useful for searching for adjustment and processing of grain.
