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 or process 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 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.
