Amazon's Shelf-Life Rules Disagree With Themselves: How to Plan Anyway

By Bernardo Campelo, Forbes Business Council E-Commerce Leader, Amazon SPN Certified provider, Amazon SP-API authorized partner, and Founder of PrepVia.

Picture a planning manager at a supplement brand with two Amazon help pages open side by side. The first says her category needs a minimum shelf life of 90 days. The second lists herbal and mineral supplements at 730 days before expiry at arrival, a few paragraphs below its own supplement example that lands at 330. She has a production run to schedule and three numbers from one company.

Nobody outside Amazon can tell her which number the receiving dock applies. I cannot either. What I can do is put every disagreement next to its two sources and give you the rule I plan by: when two Amazon pages disagree, plan to the stricter one, ask Amazon the exact question in writing, and keep a record of what you read, asked and shipped.

If your problem is a wrong date already sitting in Amazon's system, that is a different failure, covered in our post on virtual expiration dates. This post is about the decision before the shipment: what to print, where, and how much runway to send.

Five Pages, Seven Disagreements

When I read Seller Central on September 25, 2026, the rules for expiration-dated FBA inventory were spread across at least five help pages: Expiration dates on FBA products, Product packaging requirements, Plant, animal, food, and OTC products, the Food and beverages policy, and a page on expiration-dated COVID-19 products. None showed a revision date I could find, so you cannot settle a conflict by picking the newer text.

The table pairs each disagreement with its two sources, paraphrased as the pages read that day. It is a map of open questions, not a ruling.

Two of these conflicts sit inside a single page, so even one page, read top to bottom, gives more than one answer.

The Floor: 90 Days, More Than 90, Consumption Plus 90, or the Table

The first number a planner needs is how many days must be left when Amazon receives the product. The pages give four answers, and they do not measure the same thing.

The Plant, animal, food, and OTC page sets a minimum shelf life of 90 days and calls anything under 90 unacceptable. The Food and beverages policy asks for more than 90 days. Neither says whether it means total life or life remaining, or when the count is taken.

The expiration page is explicit on both points for its own rule. At check-in, a product needs enough remaining life to be consumed in full, plus 90 days, and baby formula needs at least 180. The same page then publishes minimum arrival times by category. They run from 90 days for chips and snacks, through 365 for pasta and 540 for candy, up to 730 for herbal or mineral supplements and 900 for cleaning supplies and personal care and beauty. Amazon calls the list a guide and says it is not exhaustive.

Even a single-serve snack bag eaten the day it is opened gets 90 from the table, 91 from consumption plus 90, and more than 90 from the food policy. The most specific number is the lowest of the three.

The supplement example that fails its own table

The expiration page explains its consumption rule with a bottle of 240 daily servings: 240 days plus 90, so 330 at check-in. Its table puts herbal or mineral supplements at 730. For an herbal bottle, one page gives you 330 and 730. And the table names no other supplement, so a vitamin, protein powder or probiotic has no row at all.

In these examples, every table row above 90 days sets the highest number, far above the 90-day pages. For low-floor food, the other rules can sit a day above it. No page says which one the dock enforces, so my recommendation is to plan to the highest number in the row.

The Label: Format, Font Size and the Date You Did Not Print

Three date orders and a federal rule

The packaging page allows MM-DD-YYYY or MM-YYYY. The expiration page labels its preferred numeric format DD-MM-YYYY and illustrates it with 03-15-2026, which only works month first, since there is no fifteenth month. It labels a second row DD-MM-YYYY too, shown as 15-MAR-2026, acceptable but not preferred. And it notes that Amazon reads MM-YYYY as the first day of that month.

Medical devices add a third order. The expiration page says a printed date on a device label must follow YYYY-MM-DD, citing FDA rules, and the COVID-19 products page says the same. The regulation, 21 CFR 801.18, requires device label dates in YYYY-MM-DD order, as in 2014-01-02, with exceptions such as a combination product that properly bears an NDC number. The packaging page states its two formats with no device exception.

My default: numeric, month first, four-digit year, the only order that matches both the packaging page and the expiration page's own example. Never a numeric day-first date: 04-05-2027 is April 5 read month first and May 4 read day first. A day of 12 or less stays ambiguous under the expiration page's label, so keep the date you entered on record. Avoid MM-YYYY when the real date falls late in the month, since reading it as day one can cost up to 30 days of runway. For a device, do not convert a federally formatted date on a prep bench; ask your regulatory counsel and Amazon first.

36 points on what

The packaging page puts 36-point type on the outer box and the date on each unit, with no unit size. The Plant, animal, food, and OTC page asks for the date on both product and master carton in 36-point or larger, which reads as 36 points on the unit too. On a sachet, that may not fit. My default is 36 points on every carton and the largest legible size the unit allows, with a written question to Amazon when a unit cannot carry more.

The product with no printed date

The expiration page asks for three attributes at ASIN creation, including Product Expiration Type, whose values are Expiration Date Required, Production Date Required and Shelf Life, the last for products with no printed date. The same page says every ingestible must carry an expiry or manufacturing date, and lot numbers alone are insufficient. For an ingestible, then, the Shelf Life type describes a product the same page's labeling rules do not seem to allow. My default: if a person or an animal eats it, print a date on units and cartons, then set the type to match what is printed, which is how the page says to choose it. That decision belongs in your new ASIN launch timeline, not the week cartons ship.

The Sticker: Cover the Original Date, or Never Conceal It

This conflict lands on the prep bench. The packaging page says that when the date is printed in another format, a sticker in the correct format must be applied over the original. The expiration page, under Best Practices, says: "Do not conceal the original expiry date or other product information."

When the original is in a format the packaging page rejects, nothing satisfies both. Cover it and you break the best practice; place the sticker beside it and you break the requirement. The pages also disagree on which originals need a sticker, since only the expiration page accepts a 15-MAR-2026 style date.

Neither page says which line wins, so what follows is my reading, not Amazon's. The packaging line says must, and that page warns that noncompliant inventory may be refused or disposed of at your expense, with no reimbursement. The expiration page keeps a separate list headed Requirement, and the concealment line is not on it; it sits under Best Practices. That signal is weak, since the page warns that failing its requirements can cost the selling account. So my default is to sticker over the original date and nothing else, never over ingredients, drug facts, net contents or distributor details. Photograph the original before the sticker goes on, lot by lot. If the printed date is already MM-DD-YYYY or MM-YYYY, do not sticker at all.

The Planning Rule: Strictest Reading, Measured at Check-In

You cannot resolve the conflicts, but you can stop being exposed to them. This is the default I would set for any dated ASIN until Amazon answers in writing. It is a planning choice, not a claim about what Amazon enforces.

The floor is counted at check-in, and you only control the day cartons leave your dock. After check-in, Amazon sets unsold units to unsellable when they come close to the end of the ASIN's shelf life, without saying how close, so the life left must also cover the stock you send. My formula: days needed at ship-out equal the larger of the strictest floor, or your days of supply plus a margin, plus your measured dock-to-check-in days. Measure that last number from your own shipments; our check-in time guide shows where those days go.

Illustrative numbers. An herbal supplement has a 730-day floor. You send 90 days of supply with a 60-day margin, 150, so the floor wins. Add 12 days from dock to check-in and each lot needs 742 days left when it ships. With a printed date 36 months after manufacture, about 1,095 days, the lot must ship by day 353, and production, ocean freight, customs and prep all come out of that. With a 24-month date, about 730 days, the product cannot meet the floor even if it ships the day it is made.

Now a snack with a 365-day date. The floor is 91, but 120 days of supply plus a 60-day margin is 180, so your own sell-through binds. Add 12 days and the lot must ship by day 173. For low-floor categories, your days of supply are the real constraint, not the table.

What to Ask Amazon in Writing, and What to Record

The expiration page says Seller Assistant can connect you to Selling Partner Support. Open a case per ASIN family, cite both page IDs, and ask which page and rule Amazon applies.

A support reply does not rewrite a help page, and I have seen nothing from Amazon saying it binds a receiving dock. It gives you a dated record that you asked before you shipped. Save the case number, the date and the answer word for word. Then record, by lot and shipment:

Plan as if the date that checks in is the date that stays. Amazon's COVID-19 products page says fulfillment centers cannot update expiration dates on inventory for any reason and, for COVID-19 home test kits, recommends having the product returned and updated before it is reshipped. That page covers COVID-19 products, but I would not plan on any date changing inside the building. If a lot must come back for relabeling, see the removal orders guide.

Where a Prep Center Fits, and What It Cannot Decide

A prep center is the last place a date can still be read, photographed, stickered and separated by date before Amazon. At PrepVia in Miami, we verify printed dates and apply expiration date labels in MM-DD-YYYY or MM-YYYY, the formats on Amazon's packaging page.

What a prep center cannot do is decide which Amazon page wins. We do not set your floor. We are not your regulatory advisor for food, supplements or devices, and, as our company facts page states, we are not an FDA-registered facility. Nobody can promise a unit will never be flagged. The floor is your decision, ideally backed by Amazon's written answer.

Frequently Asked Questions

What is the minimum shelf life for Amazon FBA in 2026?

Amazon's pages give more than one answer. The Plant, animal, food, and OTC page sets 90 days. The Food and beverages policy asks for more than 90. The expiration page asks for consumption in full plus 90 days at check-in, next to a category table that reaches 730 days for herbal or mineral supplements and 900 for personal care and beauty. No page says which one the dock applies, so my recommendation is to plan to the highest number that fits your product.

Does the 730-day rule apply to every supplement?

The table names herbal or mineral supplements at 730 days and names no other supplement. The same page works a 240-serving supplement example to 330 days. Until Amazon answers in writing for your ASIN, my conservative default is 730 days for any supplement, the highest supplement number on these pages.

Should I print expiration dates as MM-DD-YYYY or DD-MM-YYYY?

My default is MM-DD-YYYY. The packaging page lists MM-DD-YYYY and MM-YYYY, and the expiration page labels its preferred format DD-MM-YYYY but shows it as 03-15-2026, which only reads month first. Medical devices are the exception: the expiration page and 21 CFR 801.18 call for YYYY-MM-DD, so ask your regulatory counsel and Amazon before touching a device date.

Should a date sticker cover the original expiration date?

The packaging page says a compliant sticker must go over an original date printed in another format, and the expiration page lists not concealing the original as a best practice. No action satisfies both. My default is to cover only the date, never other label information, photograph the original first, and ask Amazon in writing for your ASIN.

Is the shelf-life minimum counted when I ship or at check-in?

The expiration page counts it at check-in. The 90-day pages do not say. Since you control only the ship date, add your measured dock-to-check-in days to the floor. Then make sure the life left also covers the stock you send, because Amazon sets units to unsellable as they come close to the end of their shelf life without publishing how close.

Does an answer from Seller Support protect my inventory?

A support answer does not change a help page, and I know of no Amazon statement making it binding on a receiving dock. It is still worth getting as a dated record that you asked the specific question before shipping. Save it word for word.

Final Take

Amazon's shelf-life rules are not hidden. They are published across at least five pages, and the pages do not agree on the floor, the format or the sticker.

You do not need to know which one Amazon enforces to plan well. Take the highest floor that fits your product, count it at check-in, check it against your days of supply, add your real transit days, and print a month-first date, the order both pages actually show. Where the pages conflict on a physical action, my rule is to follow the sentence written as a requirement and keep the photo of what you covered.

Then write it down. When the rulebook disagrees with itself, the seller with the dated record is the one who can show the plan was reasonable.
