Domestic mustard seed: Export shipments

Commercially clean (CCLN)

Export 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%.

A deduction for broken and reasonably sound mustard seed removed as dockage is allowed

• On shipments from a terminal elevator, not for direct export, of up to 0.5%
• On shipments for direct export, of up to 0.8%
• On shipments for direct export, exiting primary elevators, of up to 0.5%

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 allowed 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 allowances for broken seed in commercially clean shipments, a deduction of up to 0.2% is applied to establish net dockage for direct exports only.

Determination of dockage

Follow the procedure for normal cleaning, with the Carter dockage tester set up as follows.

You will also need the following hand sieves.

Composition of dockage

In export domestic mustard seed shipments, dockage consists of

• Material other than mustard which passes over the NumberNo. 000 riddle or remains on top of the round-hole sieve
• Material that passes through the NumberNo. .028 or NumberNo. .032 slotted hand sieve, less the applicable allowance for broken or reasonably sound small whole mustard seed
• Material removed by aspiration
• Material removed by Cleaning for grade improvement

Grading

Domestic mustard seed on export is graded in accordance with the primary and export grade determination tables.
