Screenings – Chapter 23
Official Grain Grading Guide
Composition of screenings
Screenings consist of dockage material that qualifies only for Class IV grades. Screenings are graded in accordance with the specifications in the Off-grades of Grain and Grades of Screenings order.
Show the composition of screenings in detail on all records for carlots and cargoes. The composition determines the market value of the screenings.
Whole grain in screenings
Whole grain in screenings includes wheat, rye, barley, oats, triticale, flaxseed, rapeseed, canola, domestic mustard seed and pulses.
At a terminal, process, or transfer elevator, show the percentage by weight and the grade of whole grain in screenings on all inspection records and grade certificates and as part of the grade name, if
- Shipments contain 6.0% or over by weight of whole grain which can be separated by the usual cleaning methods
- The grain qualifies for an official, special or off-grade
For example,
Grade: Refuse Screenings, less 15.0% Wheat, CW/CE Feed
Composition:
- 10.0% chaff
- 15.0% Wheat CW/CE Feed
- 8.0% large seeds
- 67.0% small seeds and dust
Total: 100.0%
Report the percentage by weight and the kinds of whole grain in the sample for samples representing shipments from primary elevators or unlicensed warehouses to destinations other than terminal or transfer elevators.
For example,
Grade: Refuse Screenings, less 15.0% Wheat
Composition:
- 10.0% chaff
- 15.0% Wheat
- 8.0% large seeds
- 67.0% small seeds and dust
Total: 100.0%
Canola, rapeseed or domestic mustard seed in screenings
Record the percentage by weight of whole seeds of small oilseeds, canola, rapeseed or domestic mustard seed, that can be separated from samples of screenings by approved sieves.
Include small, shrivelled or broken seeds which pass through the slotted sieve in the total percentage by weight of small seeds and dust.
Dockage
Dockage is not assessed for screenings except for Mixed Feed Oats.
