USDA Requirements

USDA_logoInspection Certificate

All plants and/or vegetative propagating material (including seeds cultivated, maintained or capable of propagation, distribution or sale) introduced into Puerto Rico must be free from sand, soil, earth, and other foreign matter and must be accompanied by an inspection certificate.

An inspection certificate (Phytosanitary Certificate) is required by the Puerto Rico Department of Agriculture Plant Quarantine Services, the authority responsible for enforcing plant quarantine regulations in the state. 

The certificate must provide the following information:

  • Name of the state where the material was cultivated.
Name and address of the consignee and importer.
Accepted common name or scientific name of the plant.
Assurance the material was duly inspected and is apparently free of plant pests.

3MG Packaging Instructions

Nursery and Grow-out seeds should be sent in envelopes with holes.

Envelopes should be stapled as far down as possible ensuring flap is closed.

Envelopes should be arranged by entry number in a divided box.

We recommend passing a string through the holes or placing tape over the rows to maintain envelope in place.

 Shipment should be accompanied with a file including the entries enclosed in the shipment, any specific instructions and contact information including name, telephone number and email. Also send the shipment tracking number and an electronic version of the entry list via email. This will help us to get started setting up your project before seed arrival and to ensure a smooth delivery of your precious seed.
