Currently, the Grain Code offers three official loading patterns for grain in each cargo hold:

- Full hold, trimmed ends
- Full hold, untrimmed ends
- Partly filled hold

For a partly filled hold, the grain surface is assumed to be “trimmed” to an approximate even surface at any loading level, also when the hold is near full. This implies that the space underneath the deck, fore and aft of the hatch, so called ends, must also be trimmed for levels inside the hatch perimeter. As a result, the grain must be manually shuffled up under the end girders to reduce the void.

Since trimming the ends is labour-intensive, it is not always carried out. When trimming is omitted in partly filled holds, the actual voids in the ends are larger than those assumed by following the current calculation method. As a result, the actual grain shifting moment will be larger than the calculated value.
