Buckwheat: Export shipments
Export shipments can be commercially clean or not commercially clean.
Commercially clean (CCLN)
Export shipments are defined as commercially clean when the net dockage does not exceed 2.5% of the sample weight.
Any whole domestic buckwheat removed in dockage assessment is returned to the clean sample. Dockage in shipments is reduced by up to
- 0.3% for fine attritional material which passes through the number 4.5 round-hole sieve
- 0.5% for broken or hulled buckwheat removed by aspiration or passing through the number 5 buckwheat or the number 6 slotted sieve
Not commercially clean (NCC)
Export shipments that do not meet the standards for commercial cleanliness are referred to as not commercially clean. Such shipments are permitted only with the permission of the Canadian Grain Commission.
For samples representing not commercially clean shipments approved by the Canadian Grain Commission for shipment from terminal elevators, dockage is reported to the nearest 0.1%.
Instead of the allowance for broken seed in commercially clean shipments, a direct deduction of 0.2% is applied to establish net dockage for direct exports only.
Assessing dockage for small buckwheat
Follow the primary dockage assessment procedures, with the Carter dockage tester set as follows.
| Feed control | #6 |
|---|---|
| Air control | #3 |
| Riddle | None |
| Top sieve | number 5 buckwheat |
| Centre sieve | number 4.5 round-hole |
| Bottom sieve | Blank tray |
| Sieve cleaner control | Off |
Dockage consists of the following:
- Material other than whole domestic buckwheat which passes through the number 5 buckwheat or the number 6 slotted sieve, less fine attritional material, broken or hulled buckwheat constituting not more than 0.5% of the sample by weight
- Material in excess of grade tolerances which is handpicked from the cleaned sample, other than cereal grains
- Material removed by Cleaning for grade improvement
Assessing dockage for large buckwheat
Follow the primary dockage assessment procedures, with the Carter dockage tester set as follows.
| Feed control | #6 |
|---|---|
| Air control | #3 |
| Riddle | None |
| Top sieve | number 6 slotted |
| Centre sieve | number 4.5 round-hole |
| Bottom sieve | Blank tray |
| Sieve cleaner control | Off |
Dockage consists of the following:
- Material other than whole domestic buckwheat that passes through the number 6 slotted sieve, less fine attritional material, broken or hulled buckwheat constituting not more than 0.5% of the sample by weight
- Material in excess of grade tolerances which is removed by aspiration, other than whole domestic buckwheat
- Material in excess of grade tolerances which is handpicked from the cleaned sample, other than cereal grains
- Material removed by Cleaning for grade improvement
Grading
Buckwheat on export is graded in accordance with the primary and export grade determination table.
