What Does FDA Labeling Actually Require for Food and Supplements?

Every food or dietary supplement sold in the US must meet the labeling requirements in 21 CFR Part 101: product identity, net quantity in metric and US units, a Nutrition Facts or Supplement Facts panel, an ingredient list, the 9 major allergens, the responsible party's name and address, and all mandatory content in English. Get it wrong and the consequence isn't a warning, it's port detention, import refusal, or exclusion from retailers like Amazon.

For an international founder, the label is the first commercial asset the FDA, the importer, the retailer, and the consumer ever evaluate. It is also, statistically, one of the most frequent reasons foreign products sit detained at a US port unable to sell.

01Does the FDA Approve Labels Before You Sell?

No, and that surprises most founders. The FDA doesn't pre-approve labels. The system runs on manufacturer responsibility and after-the-fact enforcement, meaning your product can enter the market with a defective label until an inspection, a port review, or a competitor complaint triggers the consequences. Preventive compliance, validated before printing and before shipping, is the only strategy that actually pays off.

02What Must a Food Label Include at Minimum?

• Statement of identity, the product's common name, prominently displayed on the principal display panel.
• Net quantity in both metric and US units (e.g., "12 fl oz (355 mL)"), in the panel's bottom third. Metric-only quantities are one of the most common errors on imported products.
• A Nutrition Facts panel in the current format: bold, large-type calories, a separate added-sugars line in grams and % Daily Value, vitamin D and potassium as mandatory nutrients, and serving sizes based on actual consumption.
• An ingredient list in descending order by weight, common names, in English.
• The 9 major allergens under FALCPA as expanded by the FASTER Act: milk, egg, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame (added 2023, still missing from many Latin American-origin labels).
• Manufacturer, packer, or distributor name and full address.

The FDA updated its general food labeling compliance program (7321.005) in June 2025, tightening review of both domestic and imported products. Label surveillance isn't shrinking, it's being systematized.

03How Are Supplements Different, and Riskier?

Supplements fall under DSHEA (the Dietary Supplement Health and Education Act) with their own rules, and the mistakes here don't just trigger rejection, they can legally turn your supplement into an unapproved drug. Required elements: the identity statement including "dietary supplement" (or a specific variant), a Supplement Facts panel (not Nutrition Facts, with its own format under 21 CFR 101.36), an "other ingredients" line, the same 9 allergens, and US contact information for adverse-event reports.

If your label claims to cure, treat, or prevent a disease, even in the Spanish translation on the package, the product stops being a supplement and becomes an unapproved drug. That single word can trigger a warning letter and an inventory hold.

04What's Changing Between 2026 and 2028?

January 1, 2026 is the uniform compliance date for final labeling rules published in 2023 and 2024. January 1, 2028 covers rules published 2025 through 2026. February 25, 2028 brings a new definition of the "healthy" claim, based on added sugars, sodium, saturated fat, and food groups. A front-of-package labeling proposal, requiring saturated fat, sodium, and added-sugar levels on the main panel, is moving through the process with staggered implementation by company size, alongside a phase-out of synthetic petroleum-derived dyes like Red No. 40 and Yellow No. 5. A brand designing US packaging today should reserve front-panel space and reassess its coloring formulation before printing two years of inventory.

05What Actually Happens When a Label Fails?

It escalates fast. Detention and import refusal hold the product at port, forcing re-export, destruction, or supervised re-labeling, with storage fees accruing daily. Repeated rejections can trigger an Import Alert, an automatic detention on future shipments without physical examination, shifting the burden of proof to you on every batch. Warning letters are published on the FDA's site with your company's name, visible to banks, investors, and retailers running due diligence. And Amazon, Walmart, and serious distributors audit labels before listing, so a nonconforming label closes channels before the FDA even gets involved.
