What are Transaction Certificates?
OTCO understands the importance of trade to your business. We work to create opportunities for trade both domestically and internationally. OTCO offers many services to help you get official transaction certificates.
Transaction Certificates are documents that confirm the organic certification of a product in trade. They may be needed for export, import, or voluntarily, depending on the country. Examples of transaction certificates include Certificates of Inspections (COIs), TM-11, GB-COI, or NOP Import Certificates. These documents help border authorities track organic products between countries.
If your business trades organic products, a Transaction Certificate is an important record that helps protect the organic integrity of your products.
Products requested for export must be reviewed and approved by your Client Service team prior to requesting a Transaction Certificate. OTCO’s Guide to International Trade provides an overview of each trade arrangement. If you’re trading with other countries, contact OTCO to learn about the certification requirements for the destination country. Please contact export@tilth.org for any questions regarding transaction certificates.
