How to Vet a Third-Party Logistics Provider for Supplements
Your 3PL handles your finished product after manufacturing. A bad one can ruin shelf life, break lot traceability, and leave you unable to execute a recall. This guide covers what to check before you sign.
Dietary supplement manufacturers must comply with 21 CFR Part 111 (Current Good Manufacturing Practice for dietary supplements). This includes requirements for personnel, facilities, equipment, production, laboratory operations, and record-keeping.
Why 3PL Selection Matters for Supplements
Dietary supplements are regulated products. The FDA holds the brand owner responsible for product quality through the entire supply chain, including storage and distribution. If your 3PL stores product in a hot warehouse and potency degrades, the FDA cites your company, not the 3PL.
Beyond regulation, your 3PL directly affects customer experience. Wrong product shipped, expired lot sent out, damaged packaging from poor handling: these are the problems that generate returns, chargebacks, and negative reviews.
Non-Negotiable Requirements
These are not preferences. A 3PL without these capabilities creates regulatory and operational risk for a supplement brand.
FDA facility registration
Required under 21 CFR Part 1.225 for any facility holding dietary supplements. Ask for the registration number and verify on the FDA database. Re-registration is required biennially in even-numbered years.
Temperature-controlled storage
Continuous temperature monitoring with automated alerts. Ask to see their temperature logs and what happens when a sensor triggers an alarm. Products stored outside spec lose potency and may become unsafe.
Lot-level traceability
The 3PL must track which lot numbers went to which customers. Without this, a recall becomes a full product recall instead of a targeted one. Ask how they handle FIFO (first in, first out) rotation by lot.
Pest control program
Documented pest management with regular inspections. Supplements stored near food products attract pests. Ask for their pest control vendor contract and inspection schedule.
Insurance coverage
Product liability insurance and warehouse legal liability coverage. Ask for certificate of insurance with your company listed as additionally insured. Standard coverage should include product spoilage.
Questions to Ask Before Signing
- What is your shipping accuracy rate? (Target: 99.5% or higher)
- How do you handle product recalls? Walk me through the process.
- What WMS (warehouse management system) do you use, and does it integrate with my sales platform?
- What are your receiving procedures? How long between arrival and product availability?
- Do you handle Amazon FBA prep? What about international shipping?
- Can I visit the facility? (If they say no, that is a red flag.)
- What is your process when product arrives damaged from the manufacturer?
- How do you handle expiration date management and short-dated inventory?
Red Flags
- No FDA registration number provided. Either they are not registered (regulatory violation) or they do not understand supplement requirements. Both are disqualifying.
- No temperature monitoring documentation. If they cannot show you temperature logs, they are not tracking storage conditions. Your product potency and stability are unverified.
- Cannot explain their recall process. A 3PL that has never thought about recalls will not be able to execute one under time pressure. The FDA expects recall capability within 24 hours.
- Resistance to facility visits. Reputable 3PLs welcome visits. Resistance suggests the facility does not match what they describe.
- No experience with dietary supplements or food-grade products. Learning curve is real. A 3PL new to supplements will make avoidable mistakes with lot management, temperature control, and regulatory documentation.

Frequently Asked Questions
Does my supplement 3PL need to be FDA registered?
Any facility that holds, distributes, or ships dietary supplements must be registered with the FDA as a food facility under 21 CFR Part 1.225. This applies even if the 3PL does not manufacture the product. Ask for their FDA registration number and verify it on the FDA's facility registration database.
What temperature should supplements be stored at?
Most dietary supplements should be stored at controlled room temperature (59 to 77 degrees Fahrenheit or 15 to 25 degrees Celsius) as defined by USP guidelines. Probiotics and certain enzymes may require refrigerated storage (36 to 46 degrees Fahrenheit). Your 3PL should be able to show temperature logs and alarm systems for their storage areas.
How much does a supplement 3PL cost?
Typical 3PL costs for supplements include storage fees ($15 to $40 per pallet per month), pick and pack fees ($2 to $5 per order), and shipping costs that vary by carrier and destination. Many 3PLs also charge receiving fees ($25 to $50 per pallet) and minimum monthly fees ($300 to $500). Total costs depend on your order volume and SKU count.
Can I use a general 3PL for dietary supplements?
You can, but it carries risk. General 3PLs may lack FDA registration, temperature monitoring systems, lot-level traceability, or experience handling supplements alongside food-grade products. If a recall occurs, a general 3PL without lot tracking cannot help you identify which customers received affected product. Supplement-experienced 3PLs handle these requirements by default.
