Most 3PLs will say yes to expiry rotation, lot tracking and the right storage. A good answer goes further and explains how each one works on their floor.
A supplement 3PL has to keep a dated, regulated product in good order from the day it arrives until a carrier takes the parcel. Start by asking:
A partner that answers these in detail, and can show you the records, is usually one set up for supplements. For our part, we capture lot and expiry at the dock, and each pick can be scanned against the order before it ships.

Supplements come with expiry dates, lot numbers and recall duties that clothing and general merchandise don't have, and those three shape most of the daily work in nutraceutical fulfillment. Moving them to the wrong partner puts you at risk with regulators and with your customers. A generalist warehouse may ship a lot that is nearly out of date. It may miss orders when a recall has to be traced, or store heat-sensitive product outside the range printed on its label.
Ask a 3PL whether it does something and it will almost always say yes. Ask it to show you how. Which system makes the decision, when does it happen, and where is it recorded? A warehouse that relies on staff remembering the rule will have trouble showing you any of the three.
1. Does your warehouse system enforce FEFO, or do pickers keep track? FEFO means first-expired, first-out: the lot with the nearest date ships first. Nearly every 3PL claims it, and few buyers check. Ask whether the warehouse system sends the picker to the nearest-dated lot, what it does with a unit close to its date, and who sets that threshold. Without a system-directed pick there is no real rotation rule (why that matters). We capture lot and expiry at receiving, and BestOMS picks your lots by a rule we agree with you when we set up your account.
2. Do you track by lot, or only by SKU? A recall names a lot. A partner that counts stock only by product can't say which orders got units from the affected batch, so one bad batch becomes a pull of your whole catalog (how lot-level tracking works). Ask whether the lot number is recorded at receiving and carried onto every order that ships, so the orders that received one lot can be looked up. We record the lot when stock arrives and attach it to each order it ships on, which is what lets a brand narrow a recall to one lot.
3. Are you registered as a food facility, and is that the same as cGMP? A 3PL that holds finished supplements doesn't make them or pack them for the brand, so it isn't a manufacturer or a co-packer. It does count as a food facility for FDA registration, and it holds product under the holding rules of 21 CFR Part 111. Registration and cGMP are different, and our guide to what an FDA-registered facility means for supplements sets them side by side. Ask about each one by name. Meeting cGMP is the job of the brand on the label, so ask to see the procedures and the receiving, storage and lot records behind them. Ask our team the same two questions about the building your stock would sit in.
4. Can you hold the storage conditions my products need? It depends on the product. A 3PL that says every supplement needs cold storage doesn't know the category, and one that says none do is putting your probiotics at risk. Some probiotics, softgels and gummies have label limits, and many capsules and tablets need nothing special (storage needs by product type). Ask what temperature and humidity range each building holds, in numbers, and compare it with the storage statement on each label. We don't hold a set range, so a product that needs one belongs with another provider.
5. How do you keep look-alike SKUs and different doses from being mixed up? A 30-count and a 60-count of the same product, or a 500mg and a 1000mg in identical bottles, are the pairs most often shipped wrong in this category. Ask whether each pick is scanned against the order before it ships, and how the partner measures accuracy on those near-identical SKUs. We scan picks against the order at pack-out, so the barcode tells a 500mg bottle from a 1000mg one. Orders in by the cut-off can ship the same day.
6. How do you handle a New Year rush or an influencer launch without running out of stock or overstaffing? Supplement orders come in spikes. Resolution shoppers arrive in the first quarter, and a creator's launch can multiply daily volume overnight. Ask for a plan built on your forecast. "We scale up when it gets busy" isn't a plan. We plan capacity against your forecast, so bring your first-quarter and launch calendar to the call.
7. How is your pricing set up, and where are the surcharges? You want to see what drives your cost, rather than a per-order number quoted before anyone has looked at your products. Ask which kinds of handling are charged separately and which of them apply to your SKUs, and get the list of surcharges at the start. Don't accept a made-up per-order benchmark from anyone, because supplement pricing depends on how your particular products have to be handled. Inspecting and restocking returns is part of our returns and reverse logistics service.
Put the same seven questions to every partner you're considering. Give more weight to an answer that explains how something works than to one that just sounds keen. "Yes, we do FEFO" tells you very little. "Our system directs each pick by expiry date, and here's what it does with a lot below the limit" tells you a great deal. Notice which partners name the system, the record and the storage conditions, and which ones stay general.
Our answers come from one platform rather than a spreadsheet, and our lot, expiry, and FEFO control service covers the first two questions, alongside the barcode scan on every pick and lot-to-order records for a recall. Bring your real SKU list to the call, and compare what each partner tells you.
Ask whether the warehouse system enforces FEFO or leaves it to the people picking. When the system directs the pick, it sends staff to the nearest-dated lot, and it can be set to flag or hold units close to their expiry date. Without that, rotation depends on someone remembering to check the date. This is one of the clearest differences between a 3PL ready for supplements and a generalist. It's also easy to check, because a partner that has it can show you how it works.
A facility that holds dietary supplements registers with the FDA as a food facility under 21 CFR Part 1, Subpart H, and it holds product under 21 CFR Part 111. Registration and cGMP are different things, so ask about each one separately. Registration puts the facility on the FDA's list, while cGMP describes the written procedures and quality checks under which product is held. Meeting cGMP for a product is the brand's responsibility, but the warehouse should still be able to show you its procedures. Ask each partner about both, and ask our team the same.
Find out whether the lot number is recorded at receiving and carried onto every outbound order. That record is what turns a recall into a pull of one lot and the orders that received it, rather than a guess across the whole catalog. Tracking by SKU alone can't connect a lot to those orders. We record each lot against the orders it ships on, so a brand can find every order that received an affected lot.
No. It depends on the product. Many probiotic strains call for cool or refrigerated storage to keep their live culture counts (CFU). Fish oil, softgels and gummies are sensitive to heat and moisture. Many capsules and tablets need nothing beyond room conditions. A 3PL that says every supplement needs cold storage, or that none does, doesn't know the category. Ask what temperature and humidity range each building keeps, in numbers, and check it against each label. Ours are dry and ambient, with air-conditioning in some buildings, which is not the same as holding a set temperature or humidity range.
Accuracy should be high enough that mix-ups between doses and counts are rare, and it should come from a barcode check rather than a glance. Identical bottles in different doses or counts are the pairs most often mixed up in this category, so ask for the accuracy figure on your look-alike SKUs in particular, and how each pick is checked. We scan each pick against the order before it ships, to catch the wrong dose at the packing bench.
