Subject: Procurement for Greenfield Agricultural Tech - Blanket Exemption Request

Hi Sarah,

I’m reaching out regarding our upcoming procurement for our research facility. We are planning to acquire a significant amount of specialized sensors and automated irrigation controllers from your company for our ongoing agricultural product development. 

As we discussed during the conference last week, we are looking to establish a blanket purchase exemption for these items, as they are used directly in our crop production and agricultural experiments. Our company, Greenfield Agricultural Tech, is based at 4500 Orchard Way, Suite 200, Indianapolis, IN 46204. 

I’ve attached the necessary details for our tax documentation. We are a registered Indiana business; our TID is 1234567890 and our LOC is 001. We fall under the farmer exemption category, as these sensors are essential to the agricultural production processes we manage on-site. 

Please keep this on file for our future orders throughout the 2026 fiscal year. I am signing this as the Director of Operations. If you have any questions, feel free to call me directly at 317-555-0199. Thanks for your help getting this sorted out before our next quarterly budget review.

Best,
Marcus Thorne
Director of Operations
Greenfield Agricultural Tech
