APHIS Issues Notice of Decision to Add Taxa of Plants for Planting that are Quarantine Pests or Hosts of Quarantine Pests to the Lists of Plants for Planting Whose Importation is Not Authorized Pending Pest Risk Analysis

Washington, D.C., June 3, 2021 – The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has decided to add 26 taxa of plants for planting that are quarantine pests (weeds), all Myrtaceae taxa (when destined to Hawaii) and 43 other taxa of plants for planting that are hosts of 17 quarantine pests, to our lists of plants for planting whose importation is now not authorized pending pest risk analysis (NAPPRA). APHIS took public comment on the scientific evidence we used to determine these plants are quarantine pests or hosts of quarantine pests. This notice responds to the comments we received and finalizes the scientific evidence used to support the decision sheets.

Plants can carry a wide variety of pests and in some cases, the plant themselves are the pest. For this reason, APHIS does not authorize the importation of certain plants for planting pending pest risk analysis (PRA), a process that evaluates the pests and diseases associated with a commodity. Upon request, APHIS will develop a PRA evaluating the potential importation of a plant on the NAPPRA list. Based on the PRA results, APHIS will either remove the taxon from the NAPPRA list from the country or countries for which we conducted the PRA, and then allow its importation subject to general requirements, allow its importation subject to specific restrictions, or continue to prohibit its importation.

A complete list of taxa that APHIS has added to the NAPPRA list and the restrictions placed on their importation can be found on the APHIS website at: You may view the data sheets and comments in the Federal Register at: Enter APHIS-2018-0066 in the Search field.
