Quick answer: Selling hay well is a documentation problem before it's a marketing problem. (1) Define the sale lot precisely — field, cutting, species, moisture, bale dimensions and count. (2) Have a representative sample pulled to your lab's current protocol and tested on a dry-matter basis. (3) Disclose mold, weeds, foreign-object risk and any feed or pesticide restrictions in writing, and never call hay a universal grade you haven't verified. (4) Price it by unit and basis against current, verifiable market evidence. (5) Prove the weight on a legal-for-trade scale where your state requires one. (6) Put the terms in writing before the truck loads, and before you release the hay, confirm the payment's current, method-specific status directly with your own financial institution under that institution's rules — don't treat a merely initiated or account-available payment as proof of its authenticity or finality. List only through channels whose current terms you verify yourself.
Who is writing this. XES Netting manufactures bale net wrap for round balers — we are not a hay broker, buyer, testing laboratory, weights-and-measures official, or attorney, and we have no stake in which channel, price, or buyer you choose. This guide explains a documented process for defining, testing, disclosing, pricing, weighing, and contracting a hay sale. It is general education, not professional, legal, or lab-specific advice for your transaction; confirm requirements with your state weights-and-measures office, your testing lab, and your own counsel before you rely on anything here.
A hay sale that goes smoothly is one where the buyer can independently verify almost everything you told them: what the lot is, what a lab found in it, what it weighs, and what you both agreed to. This guide walks through that record, in order, from defining the lot to getting paid.
Define the sale lot before you list it
A "lot" is hay from one field, one cutting, harvested under the same conditions on the same day or narrow window — the same boundary Extension sampling guidance uses when it tells you not to mix cuttings or fields in one test (see the sampling section below). Write the lot record down before you advertise anything; it becomes the spec both your listing and your sale contract point back to.
| Field | What to record |
|---|---|
| Lot ID | Field/paddock name or number, cutting number, and bale date — a reference you and the buyer both use on the sale sheet and any lab submission |
| Crop / species / mix | Species (e.g., alfalfa, orchardgrass, bermudagrass, mixed grass/legume) and the approximate stand composition if mixed |
| Cutting / harvest | Which cutting of the season, and the cut and bale dates |
| Maturity at cutting | Growth stage when mowed (e.g., pre-bud, bud, early bloom, boot, head) — growth stage materially affects forage composition and which grade categories or buyer specifications the lot can meet |
| Rain / weather during curing | Whether the windrow was rained on, how many times, and how long curing was extended as a result |
| Baled moisture and method | Moisture percentage at baling and how you measured it (probe reading or oven test), plus whether a preservative or acid treatment was applied and at what labeled rate |
| Storage since baling | Indoor, tarped, net-covered outside stack, or uncovered/ground contact, and how long |
| Binding and dimensions | Net wrap or twine, and exact package size — round bale as width × diameter (e.g., 4×5), or rectangular as length × width × height |
| Quantity | Bale count in the lot |
| Representative scale weight | An actual measured average weight from a scale — not an estimate — reported alongside the moisture basis it was taken on (see the weight section below) |
| Loading and access | Equipment needed to load (spear, grapple, forks), ground conditions, and whether the site can accommodate the buyer's or your own truck and trailer |
These are the core recommended records for a listing that "sounds good" — not a universal legal requirement, but the record a buyer will hold you to, and the record your own testing and pricing sections below depend on.
Get it sampled and tested
A representative sample, pulled the right way and tested under the receiving lab's own documented analytical methods, current proficiency testing, and quality-control procedures — NFTA-certified or an equivalent documented program — is what turns "good-looking hay" into a number a buyer can act on.
Follow the receiving lab's current protocol, not a generic rule
Sampling guidance is not fully uniform across sources. The National Forage Testing Association's Hay Probes guidance specifies at least 20 cores per sample, taken at 90° to the bale's butt ends, probing 14–24 inches into the bale — and it states that guidance without a separate instruction by bale package shape. Penn State Extension's published instructions, by contrast, core round bales through the curved side, toward the center, and core square bales through the flat end (Sampling Bales for Forage Quality Analysis, Penn State Extension). North Dakota State University Extension gives the same package-specific split in different words: sample square bales from the end, and sample round bales "across the bale at the center, not the end" (Sampling Feed for Analysis, NDSU Extension). This guide does not adjudicate between a generic, package-neutral core angle and a package-specific entry face — no single published source resolves that gap, including this one.
Don't resolve that gap yourself. Before you core anything, get the current instruction sheet from the lab you're actually submitting to, and follow it exactly: which package it wants (round or square), how many cores per lot, how bales are selected (at random, not the best- or worst-looking ones), which face and angle to enter, and how deep to probe. The NFTA runs a laboratory proficiency-certification program — check that your chosen lab currently participates before you ship a sample. Record and keep with your results: the lab's name, the date you submitted, the test method used, its proficiency/QC status, and the sampling details you actually followed — package, core count, entry location, orientation, probe depth, and the corer/probe used.
What to test, and on which basis
Report and compare results on a dry-matter (DM) basis whenever you're comparing lots or grades — an as-fed number changes with moisture and isn't a fair comparison across lots. Have the lab report both as-fed and DM values, and keep the moisture reading tied to the same sample.
A standard forage panel covers dry matter, crude protein (CP), neutral and acid detergent fiber (NDF/ADF), an energy estimate (TDN or relative feed value/quality), ash, and mineral content. Beyond that panel, add a targeted test only when the lot's history or your intended sale gives a specific reason to — and treat each as a professional call, not a routine add-on for every load:
- Nitrate — drought-stressed growth, heavy nitrogen fertility, or known nitrate-accumulating species/weeds in the stand
- Mycotoxin — visible mold, heating, or a known wet-baling history
- Endophyte / ergovaline — tall fescue going to broodmares, late-gestation animals, or other endophyte-sensitive classes
- Non-structural carbohydrate (NSC) — hay intended for horses with a diagnosed metabolic condition
- Cantharidin — alfalfa cut in a region and season with known blister beetle activity, destined for horses
A clean routine panel, or a negative result on any one of these targeted tests, clears only what was tested, in that sample, at that time. It is not a blanket safety guarantee for the whole lot, and it should not be presented to a buyer as one.
Disclose what the lab and your own inspection find
Testing tells you the nutrient picture; a walk through the lot tells you the rest. Disclose both, in writing, before the sale:
- Mold, dust, or heating — any visible mold, musty odor, dust when handled, or history of internal heating after baling
- Toxic or noxious weeds — species present in the stand that are restricted, noxious, or known to be harmful to the intended class of livestock
- Foreign objects or carcass risk — wildlife, wire, baling-twine fragments, or other debris that can end up in a windrow or bale
- Pesticide, feed, or manure restrictions — any herbicide, pesticide, or manure application to the field, and any label-required harvest, grazing, or feeding restriction that applies
- Lot-to-lot variation — if bales in the same delivery come from more than one field, cutting, or day, say so and note which sample applies to which bales
Don't market hay as a universal "horse quality," "dairy quality," or "beef quality" grade on your own say-so. If you use a grade term, tie it to something a buyer can check: the buyer's own written specification, the numeric bands in USDA's published Hay Quality Guidelines (Supreme, Premium, Good, Fair, and Utility categories, defined by ADF, NDF, relative feed value, TDN, and crude protein ranges, plus visual criteria) where those categories are the ones in use, or your lab's actual reported values. None of those is a suitability guarantee for a specific animal — a buyer with a metabolic, respiratory, or other health concern in their herd needs to evaluate the actual test result against their own animal's needs, not a marketing label.
Price discovery, and where to actually list hay for sale
Checking current market prices and actually listing hay for sale are two different things, and not every current, verifiable resource does both. List only through channels whose current terms, fees, and coverage area you've checked yourself — not through a channel someone told you worked for them once.
USDA AMS hay and auction reports: price discovery, not a listing channel
The Agricultural Marketing Service publishes regional hay market news reports, including reports drawn from specific hay auctions in several regions. These reports are a price-discovery tool for checking current market values against your own lot — you don't list hay for sale through AMS itself, and AMS does not accept, broker, or post listings. A report that names or summarizes a specific auction can point you toward a real venue worth calling, but treat that as a lead only: confirm that auction's current consignment terms, next sale day, fees, and payment timing directly with its operator before you count on it as a place to sell. Confirm your area and hay type are actually covered before you rely on a report, and check the report's own publication cadence — it varies by region and report.
The channels below are places you can actually list or place hay for sale directly, once you've verified their current terms.
Your state's Department of Agriculture or Extension hay directory, if it's currently active
State hay-listing service availability and fees vary, and change over time. As one current example, the Texas Department of Agriculture's Hay Hotline is a live, self-service listing tool for hay-for-sale, hay-wanted, and transporter postings. Search your own state's Department of Agriculture or Extension site for an equivalent, and confirm it is still operating and free (or note its fee) before you build a listing around it — these programs are added and discontinued over time.
Your local sale barn, hay auction, or co-op/feed-store board
A regional hay auction or a co-op/feed-store bulletin board is still a legitimate local channel. Call ahead and confirm, directly with the operator: the next sale day, any consignment fee or buyer's premium, how the load is weighed in, and when and how you're paid. Don't rely on secondhand accounts of what an auction charges or pays — terms change and vary by facility.
A reputable online hay marketplace
Dedicated hay-listing marketplaces exist to connect buyers and sellers outside your immediate area. As one currently operating example, AllHay.com is a subscription-based hay listing site; its own terms of service describe the platform as providing "the sole service of creating an online forum within which buyers and sellers of hay and other livestock feeds may communicate and transact with one another," explicitly disclaim liability for transactions between users, and state that "all transactions are at your own risk" (AllHay.com Terms of Service). Read the current subscription fee and listing terms on any marketplace you use before you sign up — the platform is a listing tool, not a party to your sale, and it does not vet or guarantee either side of the transaction.
Agree the payment method, verify it with your own financial institution, and protect the payment
Whichever channel you use, verify its current terms yourself rather than relying on what worked for someone else. Fake-check and overpayment scams are common enough in private-party sales that the FTC publishes standing consumer guidance specifically on that pattern (How To Spot, Avoid, and Report Fake Check Scams, Federal Trade Commission); that guidance addresses fake checks and overpayments, not every payment method — a wire, ACH transfer, or other instrument carries its own risk profile and its own reversal and finality rules, which differ from a check's and from each other's:
- Agree the payment method and amount with the buyer in writing before the load is scheduled to move
- Confirm the buyer's identity before you agree to the sale; meeting the buyer or having the hay picked up in person can help with that identity check, but in-person pickup does not by itself confirm the payment's current, method-specific status with your own financial institution
- Before you release the hay, confirm directly with your own bank, credit union, or other financial institution — not the buyer, and not a number or link the buyer gave you — the current, method-specific status of the payment under that institution's own rules; funds showing as "available" in your account do not by themselves prove a payment is authentic or final, a fraudulent check can sometimes take a bank weeks to identify even after it has shown as available, and reversal and finality rules differ by payment method and by institution
- Never refund an overpayment, and never share online banking credentials or a one-time verification code with a buyer or platform "to confirm payment" — legitimate payment confirmation never requires either
Price it on a unit and basis a buyer can check
State the price as a unit and a basis, not just a number: dollars per bale, dollars per as-is (as-fed) ton, dollars per dry-matter ton, or dollars per delivered ton. Compare your asking price against current, regionally comparable evidence — the same USDA AMS hay reports referenced above, for hay of a comparable type and quality in your area — and adjust for what actually differs between your lot and the report's benchmark: your lab-tested quality relative to the report's grade categories, lot size, handling and loading requirements, storage condition, and who is paying for transport. A generic national or historical price is not a substitute for a current, regional, quality-adjusted comparison.
When a sale is priced by weight, the scale used to determine that weight is governed by your state's weights and measures law, and a legal-for-trade scale is required where your state's law calls for one on a commercial transaction. An average farm scale is not automatically legal for trade — see the weight section directly below for what that requirement covers.
Prove the weight
A representative scale weight, not an estimated one, belongs in your lot record and your sale sheet. NIST's Handbook 130 publishes the National Conference on Weights and Measures' model laws — including the Uniform Weighmaster Law and device-accuracy requirements referenced from NIST Handbook 44 — together with a summary of which states have adopted which parts of that model. Handbook 130 is that model and summary; it is not itself every state's law, and adoption varies by jurisdiction. What actually governs your transaction is whichever version, if any, your own state has adopted.
Practically, that means: ask your own state's weights and measures office (not a neighboring state's rules, and not this guide) whether your specific transaction and payment method require legal-for-trade equipment, and if so, what that requires where you sell — a type-approved device, inspection and sealing by the state or local weights-and-measures authority, and/or weighmaster or public-scale documentation. Confirm where a certified public scale is available to you (a licensed truck scale, feed mill, grain elevator, or co-op scale, for example), and do not represent an uncertified farm platform scale as meeting whatever legal-for-trade requirement applies until your state's office confirms it does.
Put it in writing: sale sheet and contract
A written sale sheet protects both sides and gives you a document to point to if anything is disputed later. University Extension guidance on marketing hay recommends explicitly settling the point of sale, the pricing terms, tonnage/quantity, how long the price is good for, and payment terms before the sale happens (Factors to Consider When Marketing Hay, University of Wisconsin Extension). Sample hay sale contract templates come from two different kinds of source: land-grant Extension programs, such as Kansas State Research and Extension's Hay Sale Agreement, and industry associations, such as the Idaho Hay & Forage Association's Standard Hay Contract — an industry-association template, not a land-grant Extension one. Either is a useful starting draft, not a substitute for your own state's contract law or your own attorney's review — both take precedence over any template's wording.
What a complete sale sheet or contract should cover
- Both parties' names and contact information
- The lot reference and its full specification (see the lot record above)
- Quantity, with an agreed tolerance for bale count or weight variance
- How the sample was pulled, tested, and how the buyer can inspect or independently test before accepting, plus the process for rejecting or adjusting price if a test comes back materially different
- Price, unit, and basis (as-fed vs. dry-matter, delivered vs. farm-gate)
- Deposit and payment terms, including method and timing
- Sales tax, if applicable in your state
- Who loads, and who is responsible for delivery and unloading
- Road and weight compliance for the haul, and who is responsible for any permit
- The point at which title and risk of loss transfer from seller to buyer
- What happens if weather or scheduling delays the pickup or delivery
- How a claim, shortage, or quality dispute after the sale gets resolved
- Signatures and date from both parties
Don't assume a shorthand term like "FOB" carries one universally understood meaning for a hay sale — write out, explicitly, where the hay changes hands and at what point risk and cost responsibility shift, rather than relying on an abbreviation to do that work for you.
Listing template
A listing built directly from your lot record covers what a serious buyer needs to see before they call: lot ID and location (general area, not a home address, until you've screened the inquiry); species/cutting/maturity; baled moisture and storage; bale binding and dimensions; quantity available; test summary (lab name, date, DM-basis key values) or an offer to share the full report; asking price, unit, and basis; and whether delivery is available.
Pre-load checklist
Before the truck leaves, confirm: the sale sheet is signed by both parties; the payment's current, method-specific status has been confirmed directly with your own financial institution under that institution's rules, not merely initiated or account-available; the scale ticket and moisture reading are recorded and attached to the lot; the load is properly secured; the delivery address and on-site contact are confirmed; and any pesticide, feed, or manure restriction has been disclosed to the buyer in writing.
Delivery, if you offer it
Delivery is optional, and it shifts cost, time, and liability onto you — it is not a guaranteed additional profit. Don't treat cargo securement as a do-it-yourself judgment call. If you offer delivery:
- 49 CFR Part 393, Subpart I sets federal cargo-securement standards, but Part 393 itself covers commercial motor vehicles (CMVs) as federally defined — whether it applies depends on how your specific vehicle and operation are classified, not simply on crossing a state line. Intrastate rules vary by state and may adopt or incorporate the federal standard rather than duplicate it identically; confirm which rules actually cover your specific vehicle and haul with your state's motor-carrier or DOT office rather than assuming (49 CFR Part 393, Subpart I)
- Confirm each rating separately against the load's actual measured weight, not an estimate: the loaded vehicle's total weight against its GVWR (gross vehicle weight rating), its registration, and any applicable road weight limit; each axle's load against its own GAWR (gross axle weight rating) and axle weight limits; each tire's load against that tire's own load rating; and the coupling/tongue weight and trailer load against the hitch, coupler, and trailer's own ratings
- Check whether your specific route or permit requirement covers not just gross and axle weights but loaded width, height, and length, in every state you'll travel through, and confirm your insurance covers the load's value and the haul itself before you leave
- If you are not a qualified, insured motor carrier yourself, use one, or have your rig and load reviewed by a qualified, insured carrier or a compliance professional before you haul — that review reduces risk, it does not transfer your own responsibility for the haul, and it doesn't substitute for confirming the rules yourself with your state's office
- Agree in writing on who unloads at the destination, and confirm site access before the truck arrives
Whether delivering pays off depends on your actual mileage, fuel and time cost, and insurance — work the specific numbers for your haul rather than assuming delivery is automatically worth it.
Sell now or hold: comparing the real costs
There is no guaranteed seasonal pattern that says hay is cheapest or most expensive at a specific point in the year — compare your actual current bids (using the current regional evidence above) against what holding the lot really costs you: measurable dry-matter and quality loss the longer hay sits, especially uncovered; the storage space it occupies; the cash-flow and financing cost of an unsold asset; the fire and casualty-insurance exposure of stored hay; and the risk that the market moves against you instead of in your favor while you wait. Make that comparison with your own numbers each time, rather than assuming this year will repeat a pattern from a previous one.
The bottom line
- Define the lot precisely — field, cutting, species, maturity, weather, moisture, storage, binding and dimensions, quantity, and a real scale weight.
- Test it on your lab's protocol, on a dry-matter basis, and add a risk-specific test only when the lot's history calls for one.
- Disclose everything — quality, hazards, and restrictions — and never claim a grade you haven't tied to a real standard or test result.
- List only through channels you've verified yourself, and protect the payment before you release the hay.
- Price by unit and basis against current regional evidence, and prove the weight on a legal-for-trade scale where required.
- Put it in writing before the truck loads, covering quantity, testing, price, payment, delivery, title transfer, and disputes.
Frequently asked questions
What information do buyers expect in a hay listing?
A complete listing states the lot's species, cutting, and maturity; baled moisture and how it was stored; bale binding and exact dimensions (round as width × diameter, or rectangular length × width × height); quantity available; a summary of lab test results or an offer to share the full report; and the asking price with its unit and basis. A listing that skips these details gives a buyer less information they can independently verify.
Do I need to get my hay tested before selling it?
Testing may not be required by your buyer's contract or by applicable law in every transaction — verify what your specific sale and jurisdiction require. Regardless, a representative test is the most defensible way to give a buyer a quantifiable answer — a description or reputation alone isn't — but that answer covers only the specific analytes named, only the sample taken, and only the time it was taken. Pull the sample to your receiving lab's current protocol, test on a dry-matter basis, and add a targeted risk test (nitrate, mycotoxin, endophyte/ergovaline, NSC, or cantharidin) only when the lot's growing conditions or history give a specific reason to. No result is a total-quality assessment or a safety guarantee for the rest of the lot.
How do I price hay for sale?
State the price with a clear unit and basis — per bale, per as-is ton, per dry-matter ton, or per delivered ton — and compare it against current, regionally comparable evidence such as USDA AMS hay reports, adjusted for your lab-tested quality, lot size, handling, storage, and who pays for transport. A historical or national average is not a substitute for a current, regional, quality-adjusted comparison.
How do I prove bale weight to a buyer?
Use a real measured average weight from a scale, paired with the moisture reading taken on the same load, rather than an estimate. Weights-and-measures law is set by each state; NIST Handbook 130 publishes model laws and a summary of state adoption, but it is not itself every state's law and adoption varies. Ask your own state's weights and measures office whether your transaction requires legal-for-trade equipment and, if so, what that requires there — a type-approved device, inspection/seal, and/or weighmaster or public-scale documentation. Don't represent an uncertified farm platform scale as meeting that requirement until your state's office confirms it does.
Do I need a written contract to sell hay?
A written sale sheet or contract protects both parties and gives you something to point to if a dispute comes up later. It should cover both parties' details, the lot specification, quantity and tolerance, sampling and testing/rejection terms, price and basis, deposit and payment terms, loading and delivery responsibility, road and weight compliance, the point where title and risk transfer, a weather/delay clause, and a claims process, with both signatures. Sample templates are published by land-grant Extension programs and hay-industry associations.
Where can I list hay for sale?
USDA AMS hay and auction reports are a price-discovery tool, not a place you list hay directly — though a report naming a specific auction can be a lead worth calling to confirm current consignment terms. Verified places you can actually list or place hay for sale include your state Department of Agriculture or Extension hay directory if it's still active, your local sale barn or a co-op/feed-store board (confirm terms directly with the operator), and a reputable online hay marketplace whose current subscription fee and terms you check before signing up. Confirm the buyer's identity, and before you release the hay, confirm the payment's current, method-specific status directly with your own financial institution under that institution's rules; don't treat a merely initiated or account-available payment as proof of its authenticity or finality, regardless of which channel you use.
