Each brand requires approval from the manufacturer.  Use the SDC portal to request access to the brands you like. Go to the "Requests & Ratings" section and press the "Add Requests" button to get started. You can use the SEMA "scorecard" to measure a brand's data quality.  A Platinum brand has done more work to get good data compared to a brand rated as Bronze. You can use the "Product Lookup" in the SDC portal to preview brands first.  Look to see if they have images, titles, descriptions, and other information that would make the product look good in the store. For assistance please contact: helpdesk@semadatacoop.org 

Once you have your SEMA brand approval come through, generally speaking after selecting an approved brand (adding it to the "My Brands" tab) the system should start loading it immediately.
