3PL for DTC

Supplement Fulfillment Guide

By 3PL for DTC Editorial · Updated · How we research

Quick answer

Require four things from a supplement 3PL: 1) a current FDA food facility registration for the warehouse, since dietary supplements count as food and facilities that hold food must register; 2) holding practices that meet FDA's supplement cGMP rule (21 CFR 111), which covers anyone who holds dietary supplements, including temperature, humidity and light control; 3) lot and expiration tracking with FEFO allocation; and 4) lot-level distribution records you can pull fast in a recall.

Key takeaways

  • Facilities that manufacture, process, pack or hold food for US consumption, dietary supplements included, must register with FDA.
  • Registration is renewed every other year, between October 1 and December 31 of each even-numbered year.
  • FDA charges no registration fee and issues no registration certificate, so a "certificate" alone proves nothing.
  • 21 CFR 111 applies to anyone who holds dietary supplements, and requires written holding procedures and product distribution records.
  • FEFO allocation and a minimum shelf-life rule are what stop short-dated product from shipping.

Do supplement 3PLs need to be FDA registered?

Yes. FDA requires facilities that manufacture, process, pack or hold food for consumption in the United States to register, and FDA lists dietary supplements among the products covered. A 3PL warehouse holding your supplements is holding food.

What to know:

  • Timing: a facility must register before it begins holding food, and renew every other year between October 1 and December 31 of each even-numbered year (21 CFR 1.230). 2026 is a renewal year.
  • No fee, no certificate: FDA says there is no fee to register, and it doesn't issue or recognize registration certificates, including ones sold by private companies.
  • Not an approval: registration tells FDA the facility exists and permits inspection. It isn't an endorsement of the 3PL.

What to ask: "Is this specific building registered, and when did you last renew?" Ask for the registration number. A multi-site 3PL registers each facility, so check the one your stock will sit in.

Does a supplement warehouse need to be cGMP compliant?

FDA's dietary supplement cGMP rule, 21 CFR Part 111, applies to anyone who manufactures, packages, labels or holds a dietary supplement. The only holding exemption is for retail establishments holding product for direct sale to consumers, and it doesn't extend to warehouses.

The holding and distribution requirements your 3PL should meet:

Rule What it requires
21 CFR 111.455(a) Hold supplements under appropriate temperature, humidity and light so identity, purity, strength and composition aren't affected
21 CFR 111.455(c) Hold under conditions that don't lead to mix-up, contamination or deterioration
21 CFR 111.475 Written procedures for holding and distributing, and records of product distribution

Some 3PLs also hold third-party cGMP or food-safety certifications. Treat those as a plus, and ask to see the audit report and its date rather than a logo.

What should a supplement brand look for in a 3PL?

Use this checklist in your RFP:

  • FDA food facility registration for the specific warehouse, renewed for the current cycle
  • Written holding and distribution SOPs you can review
  • Temperature and humidity monitoring in storage areas, with logs you can request; ask what range they hold and what happens in summer
  • Mandatory lot and expiry capture at receiving
  • FEFO allocation, plus a minimum remaining shelf-life rule per channel
  • Lot-level shipment report available within 24 hours for a recall
  • Quarantine location for damaged, short-dated or held product
  • Returns policy: opened supplements are not restocked to sellable
  • Pest control program and sanitation records
  • Amazon FBA prep if you sell there (expiry labeling on carton and unit)

For the lot and expiry setup in detail, see lot tracking and FEFO.

How should you handle protein powder, gummies and temperature-sensitive formats?

Format drives your fulfillment requirements more than the category does:

Format What to plan for
Protein powder tubs and bags Weight and size drive postage and dimensional weight; ask about pallet storage rates and box-size options
Gummies and softgels Heat can deform or stick product; ask about summer storage conditions and warm-weather shipping options
Capsules and tablets Humidity control; standard ambient storage usually works
Liquids Leak prevention: bagging, cap seals, box orientation

21 CFR 111.455 requires conditions appropriate to your product, and you're the one who knows what that is. Put your storage requirements in writing in the contract or SOP.

Which 3PLs list supplement fulfillment as a specialty?

These providers list supplements as a specialty. It's a starting shortlist, not a ranking. Verify registration and lot control with each.

  • Tondo Fulfillment: Delaware and Utah warehouses, focused on CPG, food, beverage, supplement and beauty brands, with DTC, retail/B2B and TikTok Shop fulfillment on month-to-month terms with 30-day notice. Not a fit if your products are heavy or bulky or you need multi-country fulfillment.
  • Shipfusion: US and Canada warehouses with in-house software, aimed at brands shipping 2,000+ orders a month, notably wellness and consumables. Not a fit if you're well under that volume.
  • Fulfyld: a single Alabama site with published tiered pricing, aimed at roughly 500–5,000 orders a month. Not a fit if you need two-coast coverage or retail EDI.
  • Stord: fulfillment plus its own WMS/OMS for mid-market and enterprise omnichannel brands. Not a fit if you're an early-stage brand wanting published pricing; rates aren't published.

What goes wrong with supplement fulfillment?

  • Short-dated product ships because the 3PL runs FIFO, not FEFO.
  • Commingled lots in one bin make a recall impossible to scope.
  • Summer heat damages gummies or softgels in an uncontrolled building or on a hot truck.
  • Opened returns get restocked, so a customer receives a tampered product.
  • Amazon removes units within 50 days of expiry, because shelf life wasn't checked before an FBA transfer. See the FBA prep guide.
  • Registration lapsed at the last renewal and nobody checked.

Frequently asked questions

Is a supplement 3PL required to be FDA registered?

Yes. Dietary supplements are food under FDA's registration rules, and facilities that hold food for US consumption must register and renew every other year.

What does "FDA registered warehouse" actually mean?

It means the facility has notified FDA that it holds food and agreed to inspection. It isn't an FDA approval, and FDA doesn't issue registration certificates.

Do supplement 3PLs need to be cGMP?

21 CFR Part 111 applies to anyone who holds dietary supplements, so the 3PL's holding practices must meet its storage, mix-up prevention and distribution-record requirements.

How do supplement 3PLs handle expiration dates?

Good ones capture lot and expiry at receiving, allocate by FEFO and block lots below your minimum shelf-life threshold from shipping.

Can a supplement 3PL restock returns?

It can restock sealed returns if you allow it. Most supplement brands require opened returns to be disposed of rather than resold.
