You spent months getting your supplement formula right, ordered your first big production run, and shipped it off to Amazon. Then the problems start. Units get stuck in receiving. Some are marked “expired” even though they have plenty of shelf life left. A few cases get sent back, and others are quietly disposed of.
For supplement brands, this happens more often than you’d think. Supplements are expiration-dated, ingestible products, which means Amazon holds them to a tougher standard than a phone case or a t-shirt. And since Amazon ended its own FBA prep and item labeling services on January 1, 2026, getting every detail right before your inventory leaves the building is now entirely on you.
The good news? Most rejected shipments come down to a handful of avoidable mistakes. Here’s what to watch for.
Why Supplements Get Extra Scrutiny on Amazon
Amazon treats dietary supplements as a higher-risk category for a few reasons:
- They expire. Amazon has to make sure customers never receive a bottle that’s out of date, so it tracks expiration dates closely.
- People ingest them. Safety and label accuracy matter more for products customers swallow.
- Compliance rules keep tightening. Amazon has been expanding its requirement that supplement sellers verify their products through an Amazon-approved Testing, Inspection, and Certification (TIC) provider. This verification now applies to all supplement categories, not just high-risk ones like weight management and sports nutrition.
Your prep partner can’t handle your TIC verification for you. That part happens between you, your manufacturer, and your testing provider. But once your product is cleared to sell, how it’s labeled, packed, and shipped decides whether it actually makes it onto the shelf.
7 FBA Prep Mistakes That Get Supplement Shipments Rejected
1. Using the Wrong Expiration Date Format
Amazon requires expiration dates in either MM-DD-YYYY or MM-YYYY format. If your bottle says “EXP 2027/03” or shows only a lot number, Amazon may not be able to read it correctly. If your packaging shows a manufacturing date instead of an expiration date, cover it with a correctly formatted expiration date label. Otherwise, your units could be delayed in receiving or even logged as expired.
2. Forgetting the Date on the Outer Carton
It isn’t enough to have the expiration date on each bottle. Amazon also wants it on the master carton, printed in 36-point font or larger. This one detail trips up a lot of first-time sellers, because the manufacturer’s cases rarely come labeled this way.
3. Sending Inventory Too Close to Expiration
Amazon generally requires more than 90 days of remaining shelf life when your inventory arrives, and products that customers use over a longer period may need more. On the back end, Amazon removes and disposes of units that come within 50 days of their expiration date. Those units won’t be returned to you, so short-dated inventory can turn into a total loss.
The fix is simple, but it takes discipline: send your freshest lots to Amazon and keep a close eye on how quickly each SKU sells through.
4. Missing or Incorrect FNSKU Labels
Expiration-dated products can’t be commingled with other sellers’ inventory, so each unit needs its own Amazon FNSKU barcode label. A label placed over the wrong barcode, a crooked label that won’t scan, or a missing label can all cause receiving problems.
5. Labeling Bundles the Wrong Way
Selling a three-pack or a “morning and night” vitamin set? Amazon expects the bundle as a whole and each item inside it to show an expiration date in the required format. The bundle also needs to be clearly marked so it isn’t separated and sold as individual units.
6. Packaging That Isn’t Ready for the Trip
Items need to be fully sealed in packaging that can handle shipping. Glass bottles may need bubble wrap or a box, and loose items may need poly bags with suffocation warnings. If you add any of this protective packaging, the expiration date must also appear on the outside so it’s visible without opening anything.
7. A Listing That Doesn’t Match the Label
This one isn’t technically prep, but it causes plenty of headaches. Amazon expects your product images to show the full label, including the complete Supplement Facts panel, and your listing details should match what’s on the bottle. If you update your formula or packaging, update your listing at the same time.
In-House Prep vs. Working With a 3PL
With Amazon’s own prep services gone, you have two main options.
Prep in-house. You’ll need space, supplies, label printers, trained staff, and a solid understanding of Amazon’s packaging and labeling rules. This can work for small, simple catalogs, but it gets harder as you add SKUs, bundles, and seasonal spikes.
Work with a 3PL that handles FBA prep. A fulfillment partner with Amazon experience takes care of labeling, packaging, and quality checks before inventory ships to Amazon. For supplement brands, look for one that also understands expiration-dated products and works in a facility built for supplements.
How ShipWizard Handles FBA Prep for Supplement Brands
ShipWizard’s Amazon FBA prep service is built to get your inventory to Amazon ready to receive. That includes:
- Labeling and barcoding each unit
- Poly bagging and repackaging when needed
- Quality checks so shipments meet Amazon’s standards
- Special handling for expiration-dated and fragile products
- Photo documentation of prepared inventory
All of this happens in FDA-registered, cGMP-compliant, fully air-conditioned warehouses in Phoenix, AZ and Fort Lauderdale, FL. That matters for supplements, because heat can damage products like gummies and softgels long before they reach Amazon. (Read more about why temperature-controlled storage matters for supplement brands.)
Selling on more than one channel? ShipWizard can also handle Amazon FBM fulfillment and direct-to-consumer orders from the same inventory. And if your manufacturer can’t ship straight to Amazon, here’s how to build a backup FBA prep plan.
Your Supplement FBA Prep Checklist
Before your next shipment goes out, run through this list:
- Expiration dates are in MM-DD-YYYY or MM-YYYY format on every unit
- Any manufacturing dates are covered with a correctly formatted expiration date
- Master cartons show the expiration date in 36-point font or larger
- Every unit has more than 90 days of remaining shelf life (more for long-use products)
- Each unit has a scannable FNSKU label covering the original barcode
- Bundles show expiration dates on the bundle and on each item inside
- Fragile items like glass bottles are protected, with dates visible on the outside
- Your listing images and details match your current label
Caveat: Amazon updates its FBA and supplement policies often. The requirements above reflect Amazon’s published guidance as of this writing, but always double-check the latest rules in Seller Central before sending a new shipment.
Quick Questions
What expiration date format does Amazon require?
Amazon requires MM-DD-YYYY or MM-YYYY. If your packaging uses a different format, cover it with a label in the correct format.
How much shelf life does a supplement need to be accepted by FBA?
Generally more than 90 days of remaining shelf life when it arrives at Amazon. Products meant to be used over a longer period may need more.
What happens to supplements that get close to expiring at Amazon?
Amazon removes and disposes of units within 50 days of their expiration date. Those units are not returned to the seller.
Does Amazon still offer FBA prep and labeling services?
No. Amazon discontinued its FBA prep and item labeling services on January 1, 2026. Sellers now need to prep inventory themselves or work with a prep partner.
Can a 3PL handle my Amazon TIC verification?
No. TIC verification is completed with an Amazon-approved testing provider. A 3PL handles the physical side: storage, labeling, packaging, and shipping your inventory to Amazon.
Get Your Supplements to Amazon the Right Way
A rejected or disposed shipment doesn’t just cost you inventory. It costs you sales, rankings, and momentum on Amazon. Getting prep right the first time protects all three.
