A government order is awarded for a specific item. Weeks later, the manufacturer discontinues the model, or the distributor is out of stock with no date. The supplier now has three options: ship something else and hope, quietly go late, or tell the buyer. Only the third one is acceptable.
This article is about the supplier's side of that moment: who decides, what the notice should contain, and what a buyer should expect to receive. If you buy supplies, use it as a yardstick. If you supply them, this is how we work.
Why the supplier cannot decide
The contract buys what the contract says it buys. A supplier that swaps in a different model has changed the deal, even if the replacement is newer, faster or cheaper.
Two rules sit underneath this. First, under FAR 52.212-4(c), the clause used in commercial supply contracts, changes in the terms and conditions of the contract may be made only by written agreement of the parties. Second, under FAR 43.102, only contracting officers acting within the scope of their authority are empowered to execute contract modifications for the Government. Other Government personnel are told not to execute modifications and not to act in a way that leads the contractor to believe they can bind the Government.
Put together, the result is simple. A discontinued item is a request to change the contract, and the contracting officer is the person who answers it. The program office, the requester at the end of the hall, the receiving clerk or a cardholder may all be helpful, and a good supplier keeps them informed. But a casual "that should be fine" from any of them is not the written agreement the clause calls for. We wait for the contracting officer.
We do not explain contract modifications at length here. That is a topic for contracting professionals, and a sister resource covers it. The point for this article is what a supplier does before a modification is even on the table.
What happens when a supplier ships without asking
Delivering a different item than the one ordered is tendering something that does not conform to the contract. Under paragraph (a) of the same clause, the supplier may tender for acceptance only items that conform, and the Government may require repair or replacement of nonconforming supplies at no increase in price.
For the buyer, the cost is the time spent finding the problem at the dock, comparing a box to a purchase order, and starting a rejection. For the supplier, the cost is a returned shipment, a delayed payment and a record that follows the company. Nobody comes out ahead. We cover the rejection side in receiving and acceptance.
The supplier's job, in order
When we learn that an ordered item is discontinued, backordered with no firm date, or no longer available from the source we quoted, the sequence is the same each time.
- Verify the facts. Confirm with the manufacturer or distributor that the item is really unavailable, and get the replacement model they recommend, plus any change in country of origin, packaging or lead time.
- Notify early. Tell the contracting officer as soon as we know, not the week the delivery is due. The notice goes in writing, to the contact named in the order.
- Propose the closest equivalent, with a side-by-side. One page that puts the ordered item and the proposed one next to each other, spec by spec, for the exact model.
- State the effect on price and delivery. If the replacement costs less, more, or arrives on a different date, say so plainly. If the price is unchanged, say that too.
- Wait for written direction. The contracting officer may accept the proposal, reject it, ask for another option, or cancel the line. We do nothing until we have it in writing.
- Never ship silently. If the answer is slow, we follow up. We do not treat silence as approval.
If the order has several lines, the other lines should not be held hostage. Where the order allows partial deliveries, the supplier can offer to ship the unaffected lines now. We check partial award and delivery rules line by line in partial shipments on government orders.
What the side-by-side table should look like
The comparison is the most useful page in the notice. It should be specific to the exact model, not the product family. A reviewer should be able to read it in two minutes and see whether the replacement meets every requirement of the order.
| Attribute | Ordered item | Proposed replacement | Difference |
|---|---|---|---|
| Manufacturer and model | Exactly as on the order | Exactly as it will ship | Name the change |
| Each salient characteristic in the order | The requirement or value | The replacement's value | Same, better, or worse |
| Country of origin | As quoted | As it will ship | Flag any change |
| Packaging and quantity per unit | As quoted | As it will ship | Flag any change |
| Warranty | As quoted | As offered | Same or different |
| Price per unit | As awarded | Proposed | Unchanged, lower or higher |
| Delivery date | As awarded | Proposed | Days earlier or later |
Two habits make this table honest. List every characteristic the order or solicitation named, even the ones where the replacement is identical. And mark any row where the replacement is worse or different in a way a user might notice. A table that shows only the favorable rows invites a rejection and a poor impression of the supplier.
The evidence has to match the model. A data sheet for the older version does not prove the new version meets the specification. Attach the data sheet for the exact replacement.
When the order named a brand
If the original requirement named a brand, or asked for an "or equal" product under FAR 52.211-6, the stakes are higher. An equal that was evaluated and accepted at award is a different situation from a replacement proposed afterward: nobody has yet decided that the new model meets the salient characteristics. The contracting officer may want technical input before agreeing, which takes time, and that is another reason to notify early.
When the replacement is made by the same manufacturer and the data sheet shows the same characteristics, the decision is usually quick. When the replacement is a different brand, the contracting officer is effectively running a small evaluation. Our guide to brand name or equal covers how those comparisons are built and why they fail.
What buyers should ask for
If you are the buyer or contracting officer, you can set the expectation up front and avoid surprises. Ask any supplier for these:
- A written notice the moment an ordered item is discontinued, backordered or substituted at the source, with the reason.
- A side-by-side specification table for the exact replacement model, with the manufacturer's data sheet attached.
- A statement of the effect on price, delivery date and country of origin, including "no change" where that is true.
- Confirmation that nothing will ship until you answer in writing.
- A named contact who will answer the same day, so a quick yes or no does not wait in a queue.
- If the item is on a longer lead time, the option to receive other lines first.
Then decide on your side who gives the answer. If you are the contracting officer, a reply by email that accepts or rejects the proposal, with the line number and the model, gives the supplier and your file the same clear record. If the change affects price or the terms of the contract, you will take it from there under your own procedures.
What a supplier should not say
A few phrases show up in notices and signal trouble:
- "Equivalent" with no table. The word means nothing until it is compared against a specification.
- "Will ship unless we hear otherwise." Silence is not a decision.
- "The newer model replaces the old one" with no data sheet. Say how, spec by spec.
- A new part number buried in a shipping notice instead of a stand-alone request.
How Lunula Supply handles it
We verify availability of the exact item before anything ships. If something has changed, we tell the contracting officer in writing, put the closest equivalent beside the original specification, state the effect on price and delivery, and wait for written direction. We ask before any substitution, and we keep the running order report for the award updated so the change, the decision and the new date are all visible in one place. One person stays your contact through the whole thing.
If you want a supplier that handles a discontinued item this way, contact us or see what we supply. For the full list of what to expect after award, read what to expect from a government supplier.
Frequently asked questions
Can a supplier substitute a discontinued item on a government order?
Not on its own. Changes to a commercial contract's terms are made by written agreement under FAR 52.212-4(c), and only the contracting officer can execute a modification under FAR 43.102. The supplier should propose the substitution and wait for written approval.
What should a supplier send when an item is discontinued?
A written notice to the contracting officer with the reason, the closest equivalent, a side-by-side specification table for the exact model, the effect on price and delivery, and a clear statement that nothing will ship until the buyer decides.
Does the end user's approval count?
It helps, because the user knows what the item must do. But it does not replace the contracting officer's written decision. A supplier that relies on a verbal yes from someone without that authority takes the risk on itself.
What if the contracting officer says no?
Then the line does not change. The supplier and the contracting officer discuss options, which may include another equivalent, a later delivery or cancelling the line under the contract's terms. The supplier should not ship the proposed item anyway.
