A supplement brand hands its 3PL more than boxes. The warehouse becomes a regulated holder of a dietary supplement, and its picking rule decides whether customers receive fresh product or short-dated stock. This guide separates what the FDA requires of the warehouse from what stays with the brand, and shows what lot and expiry control looks like at Shopify volume.
A supplement fulfillment 3PL stores and ships dietary supplements under FDA rules for holders: it must register as a food facility (renewal window October 1 to December 31, 2026) and follow the holding, returns and records parts of 21 CFR 111. FDA issues no registration certificates. Ask for lot capture at receiving and FEFO picking, because FIFO ships the wrong lot when newer stock expires sooner.
What does a supplement 3PL do that a general 3PL does not?
A supplement 3PL records the lot code and expiration date of every unit it receives, picks by expiration date instead of arrival date, and can trace each lot to the orders it shipped in. A general 3PL tracks SKU and quantity only, which is enough for apparel but not for products with a shelf life.
In practice the differences show up in five places:
- Receiving: lot and expiry are captured per carton or pallet, and a delivery with mixed lots is split into separate inventory records.
- Storage: product is held within the temperature, humidity and light conditions on the label, and lots are kept apart.
- Picking: the system directs pickers to the earliest-expiring lot that still meets your minimum shelf life (FEFO), and blocks lots that do not.
- Shipping records: each order records which lot shipped, so a recall or complaint can be traced to customers.
- Returns: returned bottles are quarantined until someone with quality authority decides whether they can be resold. How a 3PL handles Shopify returns covers the general process.
What does the FDA require of a warehouse that holds supplements?
The FDA dietary supplement CGMP rule covers anyone who manufactures, packages, labels or holds a dietary supplement, so a 3PL that stores and ships your bottles is covered for the holding work it does. The retail exemption does not help: 21 CFR 111.1(b) states that a retail establishment does not include a warehouse that sells directly to individual consumers.
FDA's Small Entity Compliance Guide says a contractor must comply with the requirements directly applicable to the operations it performs, and that a firm holding packaged supplements in a warehouse must follow the holding and distributing requirements plus related rules such as personnel and physical plant. The brand that releases the product for distribution stays responsible for it. The table splits the main obligations as of October 2026. It is practical background, not legal advice.
| Requirement | What it says | Applies to a 3PL that stores and ships | Stays with the brand | Source |
|---|---|---|---|---|
| Food facility registration | Facilities that manufacture, pack or hold food, including dietary supplements, must register with FDA and renew every even-numbered year | Yes, as a holding facility (warehouses are named as examples); the 2026 renewal window is October 1 to December 31, 2026 | Each facility the brand operates that makes, packs or holds product registers on its own | 21 CFR 1.225, 1.227, 1.230 |
| Holding and distributing (subpart M) | Written procedures; hold product under appropriate temperature, humidity and light; prevent mixups and contamination; keep distribution records | Yes, for the holding and shipping it performs | The brand sets the storage conditions on its label and should share them in writing | 21 CFR 111 subpart M |
| Returned supplements (subpart N) | Quarantine returns until quality control personnel make a disposition decision; destroy unless salvage or reprocessing is approved | Yes, it must identify and quarantine returns | Agree in writing whose quality control makes the resale decision | 21 CFR 111 subpart N |
| Packaging and labeling (subpart L) | Rules for packaging and labeling operations, including batch production records for labelers | Only if the 3PL packages or labels the supplement, for example relabeling bottles | Applies to the brand and its manufacturer | FDA compliance guide |
| Release for distribution and specifications | The firm that releases product for distribution is responsible for it meeting specifications | No, unless contracted | Yes, through the brand and its manufacturer | FDA compliance guide |
| Records retention | Keep required records 1 year past the shelf-life date, if used, or 2 years beyond distribution of the last batch | Yes, for the records it makes (procedures, distribution, returns) | Yes, for the records it makes | 21 CFR 111.605 |
Two consequences follow. First, "FDA-registered" in a 3PL's marketing describes a legal minimum for a warehouse that holds supplements. FDA does not issue registration certificates or recognize certificates from private companies, and the list of registered facilities is not public, so ask the 3PL to confirm its registration and its 2026 renewal in writing. Second, kitting and subscription work can move a 3PL into packaging or labeling territory. If a project involves opening, relabeling or over-labeling a bottle, confirm with your regulatory advisor which subpart applies before it starts.
Do supplements legally need an expiration date?
No. FDA does not require expiration dating on dietary supplement labels, but if a brand prints one, it should have data to support the date. FDA states this in its Dietary Supplement Labeling Guide and in the CGMP compliance guide.
Most brands print a date anyway, and the channels you sell through treat supplements as expiry-dated whether or not a date is printed. Amazon considers dietary supplements subject to expiration even without a printed date. For the warehouse, this means expiry must be captured as data at receiving, not read off the bottle at the pick face.
FEFO or FIFO: which picking rule should a supplement 3PL use?
FEFO (first expired, first out) is the right rule for supplements. FIFO (first in, first out) ships the oldest delivery first, which goes wrong when a newer delivery carries an earlier expiration date, as happens when a manufacturer ships older finished goods or splits a run.
The worked example below uses illustrative numbers, not data from any brand or provider. A Shopify brand ships 10,000 orders a month at 1.5 units per order, or about 500 units a day of one SKU. Its policy is never to ship a bottle with less than 180 days of shelf life left. On November 1, 2026 it has three lots on hand.
| Lot | Received | Expires | Units | Last ship date under a 180-day minimum | FIFO picks it | FEFO picks it |
|---|---|---|---|---|---|---|
| Lot A | Aug 3, 2026 | Dec 31, 2027 | 20,000 | Jul 4, 2027 | Nov 1 to Dec 10, 2026 | Dec 1, 2026 to Jan 9, 2027 |
| Lot B | Sep 14, 2026 | May 31, 2027 | 15,000 | Dec 2, 2026 | Dec 11, 2026 to Jan 9, 2027 (all 15,000 too short-dated) | Nov 1 to Nov 30, 2026 (all within policy) |
| Lot C | Oct 26, 2026 | Oct 31, 2028 | 30,000 | May 4, 2028 | From Jan 10, 2027 | From Jan 10, 2027 |
Under FIFO, Lot B starts shipping nine days after its last acceptable ship date, so all 15,000 units fall below the brand's own standard. At an illustrative landed cost of $9 a unit, that is $135,000 of product to discount, divert or write off. Under FEFO the same inventory ships with no exceptions. The difference comes entirely from the picking rule, not from the amount of stock.
FEFO only works if three things are true: the expiry was entered correctly at receiving, the WMS enforces it at the pick (a picker cannot choose a different lot), and there is a hard block for anything inside your minimum shelf life. Ask the 3PL to show you all three on a live screen, not in a slide. Good expiry data also feeds your reorder point and safety stock planning, because short-dated stock is not really available stock.
How should lot codes be tracked from receiving to the customer?
Lot codes should be captured when inventory arrives, kept as separate inventory records through storage, and written onto every order at pack-out. That chain is what lets you answer one question fast: which customers received lot X?
- Receiving: count by lot against the packing list, record lot and expiry for each, and flag any carton with a missing or unreadable code.
- Put-away: keep lots in separate locations or license plates, so two lots of one SKU never mix in a single bin.
- Picking: scan the lot at the pick, not only the SKU barcode, so the system can confirm the right lot was taken.
- Pack-out: attach the lot to the order record, including components inside kits and subscription boxes.
- Reporting: a lot-to-order report that you can export yourself, with order number, ship date and destination.
Test it before you need it. During onboarding, pick one lot and ask the 3PL to produce every order it shipped in, with the units still on hand. A provider that tracks lots properly can do this quickly. A provider that cannot is telling you how a real recall would go. Kits are the usual weak point: see kitting and assembly services and subscription box fulfillment cost for how component tracking is priced.
What shelf-life rules apply if you also sell supplements on Amazon?
Amazon requires that expiry-dated products arrive with enough remaining shelf life to be consumed in full plus 90 more days. As of October 2026, its own example is a bottle of 240 daily servings, which needs at least 330 days of shelf life at check-in (Amazon Seller Central).
The same page sets packing rules that a warehouse has to follow: each box can contain only one expiration date per ASIN, the date entered in Send to Amazon must exactly match the date printed on the item, and a mismatch can lead to listing blocks, disposal or account deactivation. Items that arrive past expiry are marked for disposal and are not returned. If one warehouse serves both your Shopify orders and Amazon replenishment, the lot data has to be good enough to build single-date cartons. Shopify and Amazon from one warehouse covers the wider setup.
What should you ask a supplement 3PL before you sign?
Ask these questions of any 3PL and get the answers in writing, ideally in the contract or a signed operating procedure.
- Are you registered with FDA as a food facility, and have you completed the 2026 renewal? Send the confirmation.
- Do you capture lot and expiration date for every unit at receiving, and how do you handle a carton with mixed or missing lots?
- Does your WMS enforce FEFO at the pick, and can I set a minimum remaining shelf life per SKU that blocks short-dated stock?
- Is the lot recorded on every shipped order, including kit components? Can I export a lot-to-order report myself?
- What are your written procedures for holding and distributing, and what temperature and humidity ranges does the storage area keep? How is that monitored?
- How are returned supplements quarantined, and who decides whether they go back to sellable stock?
- How do you alert me to stock approaching my minimum shelf life, and how far in advance?
- How long do you keep receiving, distribution and returns records?
- If a project needs relabeling or repacking, who performs it and under which procedures?

Where does Orderfy fit?
Orderfy is a tech-enabled, modern 3PL for high-volume Shopify and Amazon brands. The warehouse is in the center of the US, in Dallas-Fort Worth, so ground shipping reaches both coasts quickly without paying for air.
- Orderfy WMS: Orderfy WMS is the proprietary inventory software we built in-house for Shopify and Amazon sellers, included for clients, so you manage your whole inventory in one place. Many 3PLs license their WMS from a software vendor. Orderfy built its own.
- Shopify: a native Shopify app with real-time inventory sync, tracking sent to Shopify as soon as a label is created, and support for split shipments.
- Accuracy: a 99.9% order accuracy rate, tracked in Orderfy WMS, with written SLAs and fee credits available.
- Receiving and launches: same-day receiving, dedicated staff who know your brand, and capacity for large surges such as product launches and limited drops.
- Records and access: photo records of shipments, order tracking at every stage in the client portal, and direct communication channels for 24/7 access to the warehouse team.
Before you sign with Orderfy or anyone else, ask the checklist questions above, including lot and expiry handling and FDA registration, and get the answers in writing. Orderfy is not the right fit for brands shipping a few hundred orders a month, or for brands that need warehouses on both coasts for one-day ground. If your products need refrigerated or frozen storage, ask before you request a quote.

Frequently asked questions
In most cases, yes. Dietary supplements are food under FDA rules, and a facility that holds food for consumption in the US must register unless an exemption applies (21 CFR 1.225). Registrations must be renewed between October 1 and December 31, 2026, or FDA treats them as expired.
FDA does not approve manufacturing facilities on their own, and it issues no CGMP certificate. A 3PL that holds supplements must follow the parts of 21 CFR 111 that apply to holding, such as written procedures, storage conditions, returns quarantine and records. Third-party audit certificates exist, but they are private programs, so ask what was audited and when.
FIFO ships the inventory that arrived first. FEFO ships the inventory that expires first. They give the same result only when every new delivery expires later than the last one, which is not guaranteed with supplements.
No. FDA does not require expiration dates on dietary supplements, but any date a brand prints should be supported by data (FDA). Amazon still treats supplements as expiry-dated products.
There is no FDA rule for direct-to-consumer orders, so it is a brand decision. Base it on how long a customer takes to finish the product plus a buffer, and set it in the 3PL's system so short-dated stock is blocked automatically. For Amazon, the rule is the consumption period plus 90 days at check-in.
The brand that releases the product for distribution stays responsible for it under FDA's CGMP framework, and it leads the recall. The 3PL's role is to quarantine the affected lot and report which orders it shipped in, which is why lot capture at pack-out matters.
Only after a quality decision. Under 21 CFR 111 subpart N, returned supplements must be quarantined until quality control personnel review them, and they are destroyed unless salvage is approved. Agree in writing who makes that call.
