Export shipments

Export shipments can be commercially clean or not commercially clean.

Commercially clean

Shipments defined as commercially clean may contain material as follows.

Definition of commercial cleanliness, canola

Grade name	Material other than canola remaining on top of round-hole sieve %		Total net dockage %
	Roughage material such as wild oats, seed pods, knuckles	Total
No. 1 Canada	0.3	0.5	2.5
No. 2 Canada	0.3	0.5	2.5
No. 3 Canada	0.3	0.5	2.5

Dockage is reported to the nearest

• 0.1% for samples representing 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 canola 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%
• On shipments ex primary elevators, of up to 0.50%

These deductions are applied to determine total net dockage for commercially clean shipments.

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 he 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:

Feed control	#3
Air control	#5
Riddle	No. 000
Top sieve	Blank tray
Centre sieve	None
Bottom sieve	None
Sieve cleaner	Off

You will also need the following hand sieves.

Round-hole sieves	Slotted sieves
No. 5	No. .028
No. 5.5	No. .032
No. 6
No. 6.5
No. 7
No. 7.5

Composition of dockage

In export grade canola, dockage consists of

• Material other than canola that passes over the No. 000 riddle or remains on top of the round-hole sieve
• Material that passes through the No. 028 or .032 slotted sieve, less the applicable allowance of broken and reasonably sound canola
• Material removed by aspiration
• Conspicuous admixture handpicked from the cleaned sample

Grading

Canola on export is graded in accordance with export specifications. Where there are no export specifications, the primary specifications are used.
