Flaxseed and solin – Chapter 11
Official Grain Grading Guide
Export shipments
Export shipments can be commercially clean or not commercially clean.
Commercially clean
Shipments are defined as commercially clean when the net dockage does not exceed 2.5% of the sample weight.
Dockage is reported to the nearest
- 0.1% for samples representing commercially clean shipments loaded from a single terminal or transfer elevator
- 0.01% for composite samples representing shipments loaded from more than one terminal or transfer elevator
A deduction for broken and reasonably sound flaxseed handpicked from the material and removed as dockage is allowed
- On shipments not for direct export, of up to 0.50%
- On shipments for direct export, of up to 0.75%
Not commercially clean (NCC)
Shipments that do not meet the standards for commercial cleanliness are referred to as not commercially clean. Such shipments are allowed only with the permission of the CGC.
For samples representing not commercially clean shipments approved by the CGC for shipment from terminal and transfer elevators, dockage is reported to the nearest
- 0.1% for samples representing commercially clean shipments loaded from a single terminal or transfer elevator
- 0.01% for composite samples representing shipments loaded from more than one terminal or transfer elevator
Instead of the allowances for broken seed in commercially clean shipments, a direct deduction of up to 0.2% is applied to establish net dockage.
Determination of dockage
Follow procedures for normal cleaning, with the Carter dockage tester set up as follows.
| “CC” | “NCC” | |
|---|---|---|
| Feed control | #3 | #4 |
| Air control | #2 | #3 |
| Riddle | None | None |
| Top sieve | Blank tray | Blank tray |
| Centre sieve | None | None |
| Bottom sieve | None | None |
| Sieve cleaner | Off | Off |
You will also need the following hand sieves.
| Round-hole sieves | Wire sieves |
|---|---|
| No. 4.5 | No. 4x14 |
| No. 3x16 |
Composition of dockage
In export grade flaxseed and solin, dockage consists of
- Material that remains on top of the wire sieve
- Material that passes through the No. 4.5 ound-hole hand sieve, less the applicable
- allowance of broken and reasonably sound flaxseed
- Material removed by aspiration
- Inseparable material up to established grade tolerances, handpicked from the cleaned sample
Grading
Flaxseed and solin on export are graded in accordance with export specifications.
Where there are no export specifications the primary specifications are used.
