1 METHODS FOR U.S. WHEAT

Hard Red Winter Wheat 300g to 6,800g 515 100 are based on protein and grainshed. Plains Grains Inc.

2 Hard Red Winter Wheat 300g to 6,800g are based on protein and grainshed. Plains Grains Inc. State wheat commissions State departments of agriculture USDA-ARS Hard Winter Wheat Quality Lab AIB International U.S. Plains Location: 100% Elevator Collection occurs when harvest is 30% complete in the grainshed. Follow-up sampling is done if a major weather event occurs that impacts quality. U.S. Pacific Northwest Location: 100% Elevator Collection begins the third week of July. Data shown in the USW Crop Quality Report is based on composite sample averages. The overall average values are weighted by export tributary. Individual samples are used to create the distributions shown in the USW Crop Quality Report.

3 California Hard Red Winter 2,300g to 2,700g 150 All samples are tested. California Location: 100% Elevator Collection begins and ends when harvest does. Data shown in the USW Crop Quality Report is based on composite sample averages.

Hard Red Spring Wheat 900g to 1,400g 800 6 are based on protein and export tributary region. USDA National Agricultural Statistics Service State Wheat Commissions NDSU HRS Wheat Quality Lab U.S. Plains Location: 30% Elevator 70% Farm Collection occurs when harvest is 15% complete in each county.

4 Hard Red Spring Wheat 900g to 1,400g are based on protein and export tributary region. USDA National Agricultural Statistics Service State Wheat Commissions NDSU HRS Wheat Quality Lab U.S. Plains Location: 30% Elevator 70% Farm Collection occurs when harvest is 15% complete in each county. Collection ends the last week of September in order to meet publication deadlines. U.S. Pacific Northwest Location: 100% Elevator Collection begins the third week of July. Data shown in the USW Crop Quality Report is based on composite sample averages. The overall average values are calculated using regional composite averages. Individual samples are used to create the distributions shown in the USW Crop Quality Report.

Soft White Wheat 600g to 1,500g 500 3 are based on protein and growing area. State wheat commissions Private and state grain grading organizations U.S. Pacific Northwest Location: 100% Elevator Collection begins the third week of July.

8 Soft White Wheat 600g to 1,500g are based on protein and growing area. State wheat commissions Private and state grain grading organizations U.S. Pacific Northwest Location: 100% Elevator Collection begins the third week of July. Data shown in the USW Crop Quality Report is based on composite sample averages. The overall average values are weighted by the number of samples received from each region. Sampling in the PNW is generally correlated to regional production. Individual samples are used to create the distributions shown in the USW Crop Quality Report.

Soft Red Winter Wheat 6,800g to 9,000g 500 18 are based on grainshed districts in each state.
