Buying Short-Dated Stock: What the Date Means

Short-dated stock is one of the few genuinely good deals in clinical supply, and it is also the one most often bought badly. The difference is not luck. It is knowing what the date on the carton actually tells you, and doing one piece of arithmetic before you order.

What”short dated” means

A short-dated product is one approaching the expiry date printed on its packaging. That is the whole definition. It is not damaged, it has not been returned, it has not been stored badly, and there is nothing wrong with it that was not true of the same batch six months ago. The only thing that has changed is how much of its stated shelf life remains.

Stock ends up short dated for ordinary commercial reasons. A distributor orders to a forecast and the forecast is wrong. A manufacturer changes a presentation and the old one stops moving. A clinic’s ordering pattern shifts and a line that turned over every month starts turning over every quarter. None of those reasons has anything to do with the product itself, which is why short-dated stock is sold at a discount rather than withdrawn.

The two dates on the carton, and the number between them

Most cartons carry two dates and one identifier, and it is worth being able to read all three at a glance:

• The manufacture date, sometimes shown as MFG or a production code. This tells you when the batch was made.
• The expiry date, usually EXP and often given as month and year only. Where only a month is shown, the convention is that the product is within its stated shelf life to the last day of that month — but if that distinction matters to your order, confirm it with the supplier rather than assuming.
• The batch or lot number, shown as LOT or BATCH. This is the one people ignore and the one that matters most if anything ever needs to be traced. Record it.

Keep a note of the batch number against the order it came in on. If a manufacturer ever issues a notice affecting a particular batch, the clinics that recorded their numbers find out in ten minutes whether they are affected. The ones that did not spend a day going through cartons.

The arithmetic that decides whether it is a good buy

There is only one question, and it is not about the discount. It is: will you use this before the date on the box?

Work it out honestly rather than optimistically. Take how many units of that line you genuinely used in the last three months, divide by three, and that is your monthly rate. Multiply by the number of months left on the stock. That is the most you should buy.

A 40% discount on stock you end up disposing of is a 100% loss, and you paid for the postage.

The common failure is buying to the size of the discount rather than to the rate of use. A line at half price is attractive precisely because it is half price, and the temptation is to take six when you use one a month and there are four months on the date. Take four.

What to check before you order

• Is the expiry date shown on the listing? If a supplier is selling short-dated stock without telling you the date, you cannot do the arithmetic above, and you should not be ordering. On Aesthetics Warehouse the date is shown on the listing itself, which is the point of having a separate page for it.
• How will it travel? Products with a cold-chain requirement do not become exempt from it because they are discounted. Confirm the shipping method before you order, not after it has left.
• Is the packaging intact and the batch number legible? Check on arrival, before it goes on the shelf. A carton you cannot read the batch number on is a carton you cannot trace.
• Does your own stock rotation actually work? Short-dated stock only makes sense if you use oldest first. If your shelf is organised by whatever came in last, the short-dated boxes will still be there in six months while you work through the long-dated ones bought after them.

Where the responsibility sits

A supplier’s job is to store the product correctly, ship it correctly, and tell you the truth about the date. A practitioner’s job is to decide whether a given product is appropriate for a given use, and that decision is a clinical one governed by the manufacturer’s instructions for use and by your own professional judgement and insurance. Nothing on this page changes either of those, and a discount does not either.

If you are unsure whether a particular date leaves you enough margin, the practical answer is usually to order less and reorder, rather than to order more and hope

How we list it

Aesthetics Warehouse keeps short-dated stock on its own page rather than mixing it into the general catalogue, with the expiry shown against each line. The Clearance page is separate again: those lines are reduced for other reasons — range changes, overstock, discontinued presentations — and are not necessarily short dated at all. Two different pages, because they are two different propositions and merging them would make both less useful.

Stock moves, so both pages change through the month. If a line matters to you, it is worth checking rather than assuming it will still be there
