Checklist before sending corn seeds

Please review this check list before you sent corn seed and make sure that:

Phytosanitary certificate is included, stating that the corn seed has been checked and found free of weeds (see here). No seed treatments are necessary.

Use a courier to send the seed if possible. Fed ex does a good job for Chile, however other companies have not worked well for us.

Include original airwaybill, invoice, and phytosanitary certificate. Get two originals of the phytosanitary certificate if possible, save one just in case there is a problem. List transgenic materials separately in the invoice and package them separately also. Make sure net weight listed in the invoice coincide with that in the box.

Planting plans and or instructions are inside the box 1 or have been e-mailed to MAS.

Make sure MAS has been sent a fax/email with a copy of the phyto and airwaybill number.

Make sure harvest/row tags have been included if needed or send them later.
