Did you ever haul "Commercially Clean Grain" to an elevator?

[TOM4CWB]

Lee/Fransisco/Adam Smith;

I was checking to see Eastern Grades vs. Western Grades of wheat and this jumped out at me!

Have you ever seen an elevator check our grain to see if it IS commercially clean BEFORE assessing dockage?

Here is the standard to be used:

"Determination of commercially clean

Dockage is not assessed on wheat samples that meet the commercially clean
specifications defined in the wheat export grade determinant tables. All samples must be
analyzed to determine if they meet commercial cleanliness standards prior to dockage
assessment. The analysis of samples which are clearly not commercially clean may
consist of a visual assessment. For example, if there is no doubt that a sample contains
more than 0.05% of small seeds without hand sieving and weighing the seeds then
dockage will be assessed using procedures defined under Determination of dockage.
Where there is any doubt regarding whether the sample is commercially clean, the sample
must be analyzed using the procedures outlined below in steps 1 through 13 to confirm
that the sample is not commercially clean prior to assessing dockage.
1. Using a Boerner-type divider, divide the sample to obtain a representative portion.
• Official samples should be at least 900 g.
• Unofficial samples should be at least 750 g.
2. Place approximately 250 grams of the sample at a time on the No. 5 buckwheat sieve
nested over the No. 4.5 round-hole sieve.
3. Move the sieves from left to right 30 times using a sifting motion. One complete
motion is approximately 10 cm from the center to one side, back to the center,
approximately 10 cm to the other side and back to the center.
4. All broken wheat passing through the No. 5 buckwheat hand sieve or the No. 4.5
round hole sieve is weighed and the percentage calculated to determine if it meets the
commercially clean specification of the grade for broken through a No. 5 buckwheat
sieve. (Column #1 in the wheat export grade determinant tables)
Note: Broken specifications differ for samples representing wheat ex primary,
terminal and transfer elevators.
5. Small seeds passing the No. 4.5 round hole sieve are weighed and the percentage
calculated to determine if they meet the commercially clean specification of the grade
for small seeds. (Column #2 in the wheat export grade determinant tables)
6. Material other than broken grain and small seeds passing through the 4.5 round hole
sieve is weighed and the percentage calculated to determine if it meets the
commercially clean specification of the grade for attrition. (Column #3 in the wheat
export grade determinant tables)
7. The sample portions remaining on top of the No. 5 buckwheat sieve and the 4.5
round hole sieve are recombined and divided using a Boerner-type divider to a
representative portion of not less than 250 grams.
8. The portion divided from step 7 is handpicked to remove large seeds (as defined in
the Glossary), roughage and wild oats.
9. The roughage material is weighed and the percentage calculated to determine if it
meets the commercially clean specification of the grade for roughage. (Column #4 in
the wheat export grade determinant tables)"

If I am reading the CWRS table correctly, a #1 CWRS needs to be .4% or less to be called commercially clean. Our combine skills aren't that good yet.

What sort of premium is there to be had to get to that level?

I have shipped numerous producer cars that have unloaded 0% dockage at port which save us the $4.50 terminal cleaning. Samples from these cars have been graded and tested by various grain companies and not one is willing to concede 0 dockage.
