Controlled Import Permits
A controlled import permit (CIP) may be issued to authorize the importation of an article whose importation is prohibited or restricted.
Check the Plants for Planting Manual to determine if a plant is restricted or prohibited.
Importing Plants or Plant Products for Experimental, Therapeutic, or Developmental Purposes
CIPs are intended for plants imported for:
- Experimental purposes: Scientific testing to collect data and perform analytical processes under controlled conditions;
- Therapeutic purposes: Specific scientific processes designed to eliminate, isolate, or remove potential plant pests or diseases;
- Developmental purposes: Evaluate, monitor, or verify plant material for plant health risks and/or the adaptability of plant material for certain uses or environments.
Not Authorized Pending Pest Risk Analysis
Taxa listed under Not Authorized Pending Pest Risk Analysis may only be imported with a CIP. The intended use of the imported plant material determines risk. CIPs are authorized for destructive analysis, limited propagation where the imported material is destroyed at the end of the trial, and propagation followed by release of the imported material from quarantine. A containment facility may be required for importation of the regulated material. The facility will be evaluated before the permit is issued. For further information on the regulations related to CIPs, see 7 CFR 319.6.
