From Red No.3 to New Natural Colors: The US Color Regulatory Timeline and Exporter Playbook

Over the past two years, US food color regulation has made its biggest pivot in decades. For food brands exporting to the US, this is not distant market news — the ban covers imported products and the countdown has started.
The timeline: three key milestones
January 2025: Red No.3 authorization revoked. Citing the Delaney clause of the FD&C Act, the FDA revoked the authorization for erythrosine (FD&C Red No.3) in foods and ingested drugs. Foods must be reformulated by January 15, 2027; oral drugs get until January 18, 2028.
April 2025: petroleum-based dye phase-out plan. HHS and the FDA announced a push to phase out petroleum-based synthetic colors from the food supply — including Blue No.1, Blue No.2, Green No.3, Red No.40, Yellow No.5 and Yellow No.6 — alongside a commitment to accelerate natural color approvals.
May 2025: three natural colors approved in one day. The FDA granted three new color additive petitions, delivering on its acceleration promise:
| Color | Shade | Petitioner | Highlights |
|---|---|---|---|
| Galdieria extract blue | Blue | Fermentalg (France) | From a unicellular red alga; covers beverages, dairy, confectionery, frozen desserts and more |
| Butterfly pea flower extract | Blue/purple/green | Sensient Colors | Adds snack categories — cereals, crackers, chips — to existing beverage uses |
| Calcium phosphate | White | Innophos | Covers cooked chicken, white confectionery coatings, glazes and more |
Once approved, any manufacturer may use these colors in the authorized uses — no individual petition required.
The push beyond the federal level
State laws and retailers are pulling the timeline forward in practice. Several states have restricted synthetic colors in school food and, in some cases, statewide retail; Walmart and other leading retailers have pledged to remove synthetic dyes from private label. For brands with global supply chains, the safest strategy is a single global formulation built to the strictest market, not regional dual standards.
The red replacement matrix
Red No.3 carries the largest volume, and its replacement deserves care:
- Beetroot red: closest shade, but limited heat tolerance — best for chilled and frozen desserts;
- Anthocyanins: strongly pH-dependent, giving bright red-to-purple in acidic systems, with good cost and sourcing availability;
- Carmine: excellent stability, but allergen labeling and religious-dietary constraints require category-by-category review;
- Blends: beetroot with annatto or anthocyanin is a common compromise in ice cream and beverages.
Action list for exporters
- Audit formulas: list synthetic colors across all SKUs, flagging Red No.3 first;
- Set the clock: use end of 2026 (retailer commitments), not January 2027, as the internal deadline to leave buffer for trials and retained samples;
- Collect compliance documents: exempt colors need no batch certification, but specifications, COAs, heavy-metal and undeclared-substance statements are still required at entry;
- Keep the evidence chain: retained samples and stability data before and after reformulation, ready for customs or litigation queries;
- Track what's next: FDA review of the remaining synthetic dyes is ongoing — expect further approvals and restrictions through the end of 2026.
