Standard Operating Procedures

Each year CWA reviews, adopts and updates, as needed, a document that governs the handling of paddy rice movement and quality settlements. This document is referred as CWA’s Standard Operating Procedures, or SOP. 

The SOP describes requirements and practices in a number of areas including: quality and grades of rice deliveries; mill and warehouse practices; use of mineral oil; shipping contamination; glass policy; scheduling and reporting of shipment of paddy rice to mill; and quality settlements. The document also lays out rules for an appeals process and arbitration.

This SOP is considered an important indication of a businesses’ integrity. Members are asked to agree to abide by the SOP by signing this document and submitting it to the CWA. A list of current signatories is provided.

foreign material prevention

Our collective efforts to ensure purity and quality of the rice we handle are crucial not only for the success of our individual operations, but also for upholding the reputation of the entire California rice industry. Contaminants and foreign materials can compromise the quality of our product, lead to costly issues down the line, and impact our relationships with customers and partners.

3. Clear Protocols: Maintain clear and effective protocols for addressing any issues that arise, and make sure these protocols are communicated and followed consistently.

4. Maintenance: Regularly maintain and clean all equipment and facilities used in the handling and storage of rice to prevent contamination.
