Market
In the United States, Sunset Yellow FCF used in FDA-regulated products is governed under the certified color additive listing for FD&C Yellow No. 6 (21 CFR 74.706) and is subject to FDA batch certification before legal use. It is permitted for coloring foods (including dietary supplements) under good manufacturing practice, with parallel listings for drugs and cosmetics and associated labeling and compliance obligations. U.S. food labeling rules require certified colors (and their lakes) to be declared by their listed names (with optional shortened forms), which creates a strong compliance dependency on correct identity and documentation. Policy direction in the U.S. has emphasized shifting away from petroleum-based synthetic dyes in foods, increasing reformulation and demand-risk uncertainty for Yellow 6 over the medium term.
Market RoleRegulated end-market and manufacturing hub for certified color additives (domestic use in food, drug, and cosmetic production; supplied by domestic and imported specialty-chemical sources)
Domestic RoleFunctional input for U.S. food and dietary supplement manufacturing, and for drug and cosmetic coloring where permitted
Market GrowthMixed (near- to medium-term)Policy- and buyer-driven reformulation pressure toward non-synthetic colors alongside ongoing use in legacy formulations
Specification
Compositional Metrics- CAS Reg. No. 2783-94-0 is specified in the U.S. CFR identity for FD&C Yellow No. 6 (21 CFR 74.706(a)(1)).
- CFR listing includes composition/purity specifications and impurity limits that are evaluated through FDA batch certification (21 CFR 74.706(b); FDA color certification program).
Grades- Certifiable straight color additive requiring FDA batch certification prior to lawful use in FDA-regulated products (21 CFR 74.706(e); FDA Color Certification FAQs).
Packaging- Supplier labeling for non-exempt (certifiable) color additives must include the FDA certification lot number assigned by FDA’s Color Certification Branch, along with required identity/use limitation information (21 CFR 70.25).
Supply Chain
Value Chain- Specialty chemical manufacture of FD&C Yellow No. 6 batch → manufacturer submits representative sample to FDA for certification → FDA issues certification for compliant batch (lot number) → distribution to U.S. formulators → incorporation into foods (including dietary supplements), drugs, and cosmetics under applicable use restrictions
- Downstream users maintain batch/lot documentation to support audits, complaint investigations, and (for imports of finished goods) border review

Transport ModeMultimodal
Risks
Regulatory Compliance HighUse of FD&C Yellow No. 6 from an uncertified batch (or a batch that fails CFR purity/specification requirements) can make FDA-regulated products unlawful to market in the United States and is a common cause of import refusals and enforcement actions.Source only from suppliers that can provide FDA batch certification (lot number) for each batch; verify certification status and maintain batch documentation through the finished-product supply chain.
Market Access MediumU.S. policy direction and buyer expectations increasingly emphasize phasing out petroleum-based synthetic dyes in foods, which can trigger rapid reformulation, delisting risk, and demand contraction for Yellow 6 in certain channels.Monitor FDA color additive communications and major retailer/manufacturer reformulation policies; maintain validated alternative color systems (certification-exempt or natural-source options) for continuity.
Documentation Gap MediumIncorrect ingredient declarations for certified colors (e.g., failing to declare the listed name/shortened form or omitting “Lake” for lake forms) can lead to misbranding risk for foods and downstream recalls or relabeling costs.Align label declarations to 21 CFR 101.22(k)(1) and maintain a documented labeling decision tree for dyes vs. lakes and for acceptable shortened forms.
Food Safety MediumBatches that do not meet CFR identity and impurity specifications can be rejected during FDA certification, creating supply disruptions and potential quality investigations for downstream manufacturers.Implement supplier qualification plus incoming QC against key CFR specifications and ensure contingency sourcing for certified lots with compatible shade/strength performance.
Sustainability- Policy and market shift away from petroleum-based synthetic dyes in U.S. foods can drive reformulation and demand volatility for FD&C Yellow No. 6 in food applications
FAQ
Does Sunset Yellow FCF / Yellow 6 require FDA batch certification for U.S. use?Yes. FD&C Yellow No. 6 is a certifiable color additive, meaning each batch must be certified by FDA before it can be used legally in FDA-regulated products marketed in the United States.
How should Yellow 6 be declared on U.S. food ingredient labels?For foods, certified color additives must be declared in the ingredient list by the name listed in the CFR (a shortened form like “Yellow 6” is allowed). If the lake form is used, the declaration must include the term “Lake” (for example, “Yellow 6 Lake”).
What labeling information should appear on containers of a certified Yellow 6 batch supplied to U.S. manufacturers?Color additive labeling must include the straight color’s name (or mixture ingredients), general use limitations, and—because Yellow 6 is certifiable—the FDA certification lot number assigned to that batch.
