Controlled Import Permits

Controlled Import Permits (CIPs) to Import Plants or Plant Products for Experimental, Therapeutic, or Developmental Purposes

A Controlled Import Permit (CIP) may be issued to authorize the importation of an article whose importation is prohibited or restricted. To identify if a plant is prohibited/restricted check the Plants for Planting Manual. 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.

Taxa listed under Not Authorized Pending Pest Risk Analysis may only be imported with a CIP (PPQ 588 application). The intended use of the imported plant material determines risk. CIPs are authorized for destructive analysis, for limited propagation where the imported material is destroyed at the end of the trial, and for 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.

To request a CIP submit a PPQ Form 588 application. Applications may be faxed to (301) 734-5786 or submitted via the Web-based permit system APHIS eFile (requires eAuthentication). We encourage using online application for a faster application process.
