Sale of Pesticides within California

If you sell pesticides on Amazon, Amazon will use geofencing to identify buyers in California.  Sellers who do sell pesticides will need to apply for new registration with the State of California.

In addition to federal Environmental Protection Agency (EPA) requirements on the sale of pesticides in the United States, further requirements apply for sales on certain pesticide products at the state level. The California Department of Pesticide Regulation (CDPR) requires the registration of certain pesticides sold in the State of California.

Amazon checks all pesticide products to confirm whether they are registered in the State of California according to the CDPR requirements. Pesticide products requiring registration that are not active in the CDPR database cannot be sold into California.

Note: This restriction will not remove the products from sale in the Amazon store, but it does mean that the product will not be available for sale into California until it is registered with the CDPR.

For details on how to register products with the CDPR, see the CDPR guide for pesticide registrants.

In addition, the State of California collects a Mill Assessment fee on the sale of registered pesticides. For sales of registered pesticides into the state of California, you may be required to pay the Mill Assessment to the CDPR. Please work with your tax or regulatory advisor or contact the CDPR directly for more information. For more details on calculating and paying the Mill Assessment, see the CDPR Mill Assessment frequently asked questions.

For more information on the requirements for selling pesticides in both California and the United States, see California Department of Pesticide Regulation (CDPR).
