Return to State Laws and Regulation Summaries


The U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Plant Protection and Quarantine Program (USDA APHIS PPQ) and the plant health agencies in each of the 50 states, regulate the shipment of nursery and greenhouse stock in an effort to minimize the spread of harmful insects, diseases, and other pests. The Federal & State Quarantine Summaries is designed as a reference tool for nursery stock growers, brokers, purchasers, and others involved in the buying selling, and interstate transport of nursery and greenhouse plant crops. It outlines the basic quarantine and other plant health requirements of APHIS, all 50 states, and the Commonwealth of Puerto Rico and Guam. The information presented here is designed as an aid to help users avoid costly delays, rejections of plant material shipments, and introduction of harmful pests into new areas.

Each State summary lists the relevant plant health agency and contact information; definition of nursery stock; general shipping requirements; and quarantines or other specific certification requirements that apply for shipment into that state.

The information contained on this site is designed as a quick reference tool only. Full information on approved treatments and documentation requirements may be needed. Working with plant regulatory agencies in your state and the destination state, as well as USDA APHIS PPQ regional offices in the case of Federal quarantines, is advised — especially when you are shipping to new markets. (Click here for a listing of State Plant Regulatory Officials contact information and their web sites).

Nursery stock quarantines and certification requirements are subject to frequent change. Though this site will be updated periodically, coordination with both your state and the destination state plant regulatory agencies may be necessary to stay up-to-date on revised requirements.

This information does not supplant or replace the Code of Federal Regulations (see Title 7 Agriculture, Chapter III APHIS), and/or state statutes. This site is designed as an aid in determining basic quarantine information, and should not be relied on exclusively when making purchasing and transportation decisions.

The information, as provided, is for informational purposes only and should not be interpreted as complete, nor should it be considered legally binding.
