Supplements are the category where a fine bottle becomes unsellable because of a date nobody read. ProShip3PL screens every supplement lot for remaining shelf life before it ships, verifies tamper seals and bottle counts at our Miami dock, applies expiration and FNSKU labels to Amazon's current dated-goods rules, and releases reserve stock first-expired, first-out. Your freshest inventory waits; your oldest sellable inventory sells.
A supplement bottle can fail FBA without a scratch on it. The co-packer printed the date as an embossed code the scanner can't read. The lot cleared the factory with fourteen months of life but sat through two slow quarters and now trips Amazon's shelf-life floor. Two production runs got mixed on one pallet, so half a carton carries a different date than its label claims.
None of those problems is visible from a Seller Central dashboard. All of them are visible at a prep bench where someone picks up bottles, reads dates, and compares lots against your paperwork. That bench work is what we sell to supplement brands: the boring, literal verification that keeps a dated category from bleeding inventory.
Since January 2026, Amazon itself no longer preps or labels units — a supplement shipment that arrives wrong doesn't get quietly fixed, and unprepped units that are damaged or lost sit outside reimbursement coverage. For a category where the product's value literally decays on a schedule, sending unscreened inventory into that system is a bet with bad odds.
Our Medley warehouse runs supplements as their own flow: date screening at intake, seal and count verification, compliant date and FNSKU labels, then a split — the earliest-dated sellable lot goes to FBA now, the rest racks as reserve and follows FEFO when you trigger a replenishment.
| Supplement prep trigger | What happens at our bench |
|---|---|
| Expiration date hard to read or coded | Printed date label applied in Amazon's required format |
| Lot near the shelf-life floor | Flagged to you before ship-in — never sent on autopilot |
| Tamper / induction seals | Spot-checked per lot; broken-seal units pulled and photographed |
| Co-packer count claims | Cartons counted, bottles sample-verified against the pack-out |
| Multi-bottle packs | Same-lot builds, sold-as-set marking, one honest date per pack |
| Reserve stock on our racks | Lot dates recorded; replenishment pulls first-expired, first-out |
Every lot's date read and compared against Amazon's current remaining-life thresholds before a shipment plan exists — short-dated stock surfaces here, not at an Amazon check-in.
Compliant date labels printed and applied to units and cartons. The full operational detail lives on our expiration-date labeling page — supplements are its heaviest user.
Shrink bands, induction seals and cap liners spot-checked at intake; any bottle arriving unsealed is segregated with photos instead of labeled and shipped.
Cartons counted against your PO, per-carton bottle counts sampled against the co-packer's declared pack-out — shortfalls documented while a claim is still live.
Two- and three-bottle packs built from matching lots, marked as sets, labeled with the bundle FNSKU — subscription-style offers without date roulette inside the pack.
Reserve lots rack with dates recorded; every replenishment trigger pulls the earliest-expiring sellable lot and hands it to the carrier within 24–48 hours.
Freight counted against your PO on arrival day; lot codes logged, condition photographed.
Lots screened against the current shelf-life floor — anything marginal goes to you as a decision, not to Amazon as a surprise.
Tamper seals verified, counts sampled, FNSKU and date labels applied clear of the facts panel.
Earliest-dated sellable stock ships to FBA; later lots rack as reserve and rotate out in date order.
Embossed and dot-matrix dates fail more than sellers expect. We apply printed date labels in the accepted format before ship-in, so the stranded-batch phone call stops happening.
Mixed lots get separated at our bench, re-cartoned by date, and documented — so FEFO stays true and the pallet doesn't carry a date lie into Amazon's system.
That's a rotation problem, not a sales problem. Keep weeks of cover inside Amazon and the balance here under FEFO — expiry becomes a managed date on a rack, not a write-off.
Intake seal checks exist for exactly this review. Unsealed bottles are pulled and photographed on day one, and only verified-sealed units carry your brand into a customer's hands.
Supplement cartons are counted against your PO on arrival, then every lot is date-screened before anything else happens. Bottles get tamper seals and induction seals spot-checked, counts verified, FNSKU labels applied without covering the supplement facts panel, and a printed expiration label added in the format Amazon's dated-goods rules call for. Cleared lots ship to FBA within 24–48 hours; the rest racks as FEFO-managed reserve.
Supplements are treated as expiration-dated inventory in Amazon's system, so the date must be present, legible and machine-friendly on the unit and on the carton where required. Amazon's category requirements also call for meaningful remaining shelf life at check-in — we screen each lot against the current thresholds before it ships and prep to the rules in force that week, not to a cached memory of them.
We flag it before it gets on a truck — that's the whole point of screening at our dock instead of Amazon's. You decide the exit: push the lot to your Shopify or FBM channel from our racks, run a promotion, return it to the manufacturer while a claim is possible, or dispose. Short-dated stock discovered by Amazon usually just becomes unsellable inventory you pay to remove.
Yes — seal condition is part of the supplement intake pass. We spot-check shrink bands, induction seals and cap liners across each lot, photograph any bottle that arrives with a broken or missing seal, and segregate those units instead of labeling them. A customer opening an unsealed supplement bottle is a review and safety problem no listing recovers from quickly.
We count cartons against your packing list and sample-count bottles per carton against the co-packer's declared pack-out. Shortfalls, overages and mixed-lot cartons are documented with photos the day the freight lands, so the discrepancy conversation happens with your manufacturer while the run is fresh — not months later when Amazon's numbers and your invoices refuse to reconcile.
Every lot racks with its expiration date recorded, and replenishment always pulls first-expired, first-out. When you trigger a send-in, the earliest-dated sellable lot goes to Amazon and later-dated stock keeps waiting. That single discipline is what keeps a supplement catalog from quietly accumulating stock that expires in storage while newer lots sold first.
On clear label real estate — never over the supplement facts panel, the ingredient list, the lot code or the manufacturer's printed date. On small bottles where space runs out, we position labels so both barcodes scan and the regulatory panel stays fully readable. Covering required label content is one of the avoidable ways supplement listings draw problems.
Yes — multi-bottle packs are assembled from same-lot bottles wherever possible so the pack carries one honest expiration date, bagged or boxed, marked as a set so Amazon doesn't split it, and labeled with the bundle's own FNSKU. The physical build process is covered in depth on our bundling service page; for supplements we add the lot-matching and dating discipline on top.
Gummies and some softgels behave like meltable inventory in a Florida summer and inside Amazon's own meltable calendar. We route those SKUs with the same seasonal logic as chocolate — timing send-ins around the meltable window and holding reserve in the warehouse rather than parking it where heat and time work against you. Our meltable inventory storage page covers the seasonal mechanics.
Send the form with your bottle count per month, number of SKUs, whether products arrive from a US co-packer or overseas, and any multipack builds you run. You'll have per-unit pricing within one business day — no setup fee, no monthly minimum, and a straight answer on anything your catalog makes unusual.
Tell us your SKU count, monthly bottle volume, where production ships from, and whether your units need printed date labels. Per-unit supplement prep pricing lands in your inbox within one business day.
