Free 45Z Proof Packet Builder

GrainIQ helps farmers organize, preserve, and control the records they may need when marketing reduced-CI grain.

GrainIQ does not promise 45Z premiums, certify tax claims, broker credits, or replace USDA FD-CIC. This free tool helps farmers prepare and protect the records buyers and verifiers may ask to review.
Why This Matters

Reduced-CI markets ask for proof.

45Z may create new value for documented reduced-CI grain. Farmers may be asked for field-level records, production practices, official USDA FD-CIC outputs, and proof of operational control. GrainIQ helps farmers prepare those records in a farmer-owned packet before sharing with anyone else.

Some information may be required to support a reduced-CI claim. Some information is commercially sensitive. GrainIQ helps farmers know the difference.

What GrainIQ Does Not Do

No premium promises. No official certification claim.

  • Does not guarantee premiums
  • Does not certify 45Z eligibility

  • Does not broker credits
  • Does not sell farmer CI data
  • Does not automatically share private records with buyers, consultants, FarmBridge, or USDA
Private By Default

The full packet stays private unless you choose to share it.

Actual yield is not copied into FarmBridge by default.
Fertilizer and nutrient records stay inside the packet by default.
Buyer and sale records stay private by default.
CI score is withheld unless the farmer chooses to disclose it.
Exact field boundaries are not copied unless the farmer chooses to disclose them.
FarmBridge receives only a metadata verification stub, not the full packet.
Buyer-facing PDF

The buyer-facing PDF is designed to be useful without requiring the buyer to create a GrainIQ account.

  • Packet ID, crop year, crop, and county/state
  • Farmer signature and FD-CIC output attached status
  • Evidence index status and verification URL
  • Optional CI score if disclosed by farmer
Advisor / consultant review

Farmers can invite a grain marketing advisor, consultant, accountant, or trusted reviewer to view a packet. Advisor access is read-only and controlled by the farmer.

The farmer owns the record. Advisors can review it only by invitation.

FarmBridge verification

Farmers may choose to add a verification record to FarmBridge showing that a signed, field-linked, crop-year-specific 45Z packet exists. FarmBridge does not receive the sensitive packet contents by default.

Built for farmer control

Reduced-CI grain markets will only work for farmers if farmers control the proof. GrainIQ is designed to help farmers organize records, preserve evidence, and decide what to share without turning every private farm detail into someone else's database.
