Overseas quotes often look better on the unit price line. The question for a brand owner is what that number leaves out: freight, import requirements, the time it takes to fix a problem, how easily you can audit the facility, and what you are allowed to say on your label. This guide lays out the trade-offs so you can compare manufacturers on total cost and total risk, not only on price per unit.
Any dietary supplement sold in the United States has to be manufactured under FDA’s cGMP for dietary supplements (21 CFR Part 111), wherever the facility is. Domestic and foreign facilities that manufacture food for US consumption, including supplements, must register with FDA (21 U.S.C. 350d) and renew that registration between October 1 and December 31 of every even-numbered year (21 CFR 1.230). 2026 is a renewal year, so it is a good moment to confirm your manufacturer’s registration is current.
The difference is what lands on you. When a finished supplement is made abroad, someone in the US has to import it, and the importer takes on obligations a brand buying from a US manufacturer does not.
None of this makes overseas production wrong. It means the overseas quote is a partial number until those costs and responsibilities are added.
Many brands assume that producing in the US lets them print “Made in USA.” Under the FTC’s rule, an unqualified “Made in USA” label requires that final assembly or processing happens in the US, all significant processing happens in the US, and all or virtually all ingredients or components are made and sourced in the US (16 CFR 323.2).
Two consequences follow. A product finished overseas cannot carry an unqualified US-origin claim. And a product made in a US facility does not qualify automatically either, because many supplement raw materials are sourced globally. If origin is part of your positioning, decide the exact wording with regulatory counsel and build sourcing around it from the start.
| Factor | US manufacturer | Overseas manufacturer |
|---|---|---|
| Unit price | Usually the higher line item | Often lower on the quote |
| Freight, duties, import compliance | Domestic freight only | International freight, duties, FSVP, prior notice, broker fees |
| Time to fix a problem | Same or nearby time zones, site visits by car or short flight | Longer feedback loops; a correction may wait for the next shipment |
| Auditing the facility | Easier to visit and audit | Requires travel or a third-party auditor |
| Cash tied up in transit | Lower | Higher, because product spends longer between production and sale |
| Who handles FDA import requirements | Not applicable | You or your importer of record |
| “Made in USA” claim | Possible only if ingredients also qualify | Not available unqualified |
Overseas production can make sense for a stable, high-volume product whose formula rarely changes, when you have an experienced importer and can absorb long lead times and inventory in transit.
US production tends to fit when you launch new products often, adjust formulas between runs, need faster reorders, want to audit your manufacturer in person, or sell through retailers that ask for detailed quality documentation on short notice.
Many brands are in the second group without realizing it: early products change more than planned, and every change costs more when the factory is weeks away.
To compare quotes fairly, build the landed cost per sellable unit:
Minimum order quantities and lead times shift this math too; we explain what drives them in supplement MOQs, lead times and capacity.
The unit price is often lower, but the landed cost includes international freight, duties, import compliance such as FSVP and prior notice, inventory in transit and the risk of held shipments. Compare landed cost per sellable unit, not the quote alone.
Yes. Supplements sold in the US must be made under 21 CFR Part 111, and foreign facilities must register with FDA. The US importer also has to verify the foreign supplier under FDA’s Foreign Supplier Verification Program (21 CFR 1.511).
Only if it meets the FTC standard: final processing and all significant processing in the US, and all or virtually all ingredients made and sourced in the US (16 CFR 323.2). Many supplements use globally sourced raw materials, so check your exact wording with regulatory counsel.
