Export shipments

Grading

Peas, on export, are graded in accordance with primary grade standards and specifications. Foreign material in cleaned or processed peas is treated as a grading factor and not assessed as dockage. Cargoes containing dockage may not be shipped except with permission from the CGC.

Processed vs Not Processed

Samples are considered to be processed or commercially clean when:

• Containing 0.2% or less of any small seeds and coarse vegetable matter and,
• Pea hulls constitute 10% or less by weight of the split peas in the sample.

To determine if the sample is processed, the following steps are to be completed:

1. Using a Boerner-type divider, divide the sample to obtain a representative portion of at least 900 grams
2. Select the slotted sieve ( #8, #9 or #11 ) that will achieve maximum removal of splits with a minimum loss of whole peas. Nest the selected slotted sieve over a No.4.5 round hole sieve. Sieve the sample, approximately 250 grams at a time, over the nested sieves.
3. Small weed seeds passing through the No.4.5 round hole are weighed and the percentage calculated
4. The portion remaining on top of the slotted sieve is handpicked to remove coarse vegetable matter and its percentage calculated
5. The percentages of small weed seeds and coarse vegetable matter are added together to determine if the total meets the processed specification
6. Splits and pea hulls are separated from the entire sample. Determine if the pea hulls constitute 10% or less by weight of the split peas

If any of the components exceed the allowable limits as defined above, the shipment become not commercially clean or not processed and dockage is assessed using procedures for primary samples. 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 form more than one terminal or transfer elevator

less a deduction of up to 0.2% to take into account the buildup of attritional material.

The terms processed and unprocessed do not apply to Feed peas.
