Fragrance Allergen Labeling Requirements: EU vs US Basics

Fragrance oils can turn a product into a brand experience, but they also carry labeling obligations that depend on the finished cosmetic, not just the raw material. Whether you are buying for hotel amenities, spa lines, or a private label candle range, you need to know which fragrance allergens must be disclosed in your target market and how to obtain reliable documentation from your fragrance manufacturer. At Aromiso, we help international buyers source fragrance oils and navigate documentation conversations with Chinese manufacturing partners.

Why fragrance allergen labeling is your responsibility

The fragrance oil you purchase is an ingredient in a finished product. Your label must reflect the final formulation, your product category, and the rules of each destination market. A fragrance manufacturer can provide data about the mixture, but it cannot decide your label for you. The brand owner, importer, or responsible person placing the product on the market carries the labeling obligation.

This distinction matters because fragrance allergen rules are not a single global standard. The EU requires certain fragrance allergens to be named on cosmetic labels when present above defined thresholds. The US does not have a parallel mandatory fragrance allergen labeling list for cosmetics. If you buy the same fragrance oil for an EU-bound body lotion and a US-bound candle, the documentation may need to answer different questions.

Do not treat a supplier’s “non-allergenic” or “safe” statement as a label decision. Ask for the underlying data, then review it for your specific product and market.

EU vs US: where the rules diverge

The EU framework is set by Regulation (EC) No 1223/2009. Fragrance allergens subject to labeling appear in Annex III, and the list has been amended over time. Check the European Commission’s current guidance for your product launch date and any transitional periods. In practice, if a fragrance oil contains one of the listed allergens above the relevant threshold for a leave-on or rinse-off cosmetic, the individual allergen name must appear in the ingredient list. The specific concentration thresholds differ by product type, so do not guess them; verify against the regulation or a qualified regulatory consultant.

The US framework is different. Under FDA cosmetic labeling rules, fragrance and flavor ingredients can generally be listed as “fragrance” or “flavor” without naming individual components. There is no separate mandatory fragrance allergen disclosure list comparable to the EU Annex III allergens. However, this does not mean the US ignores fragrance safety. Buyers selling in California should separately check whether any fragrance component is listed under Proposition 65 and whether a warning is required. Other state or retailer requirements may also apply.

Avoid these pitfalls: assuming the EU list applies to candles or home fragrance products without checking whether the product is a cosmetic under EU law; using a supplier allergen statement for a different concentration or product version; treating a safety data sheet as a label compliance document.

Because these systems overlap but do not align, a label that is adequate in one market may be incomplete or unnecessarily detailed in another. Map each product to its destination market before you order labels.

How to read a fragrance allergen list

A fragrance allergen declaration usually comes as a table or statement from the fragrance manufacturer. It may list INCI names, CAS numbers, presence or absence, and sometimes percentage ranges. Read it as raw data, not as a legal conclusion.

Here is a practical checklist:

• Confirm the declaration matches the exact product code, version, and revision date of the fragrance oil you ordered.
• Check whether the document states “present” or “not present” for each listed allergen, or only gives ranges. For EU labeling, you need enough precision to know whether a threshold is exceeded.
• Ask whether the reference list is the current EU Annex III or an older version. If the document references only a historical list, request an update.
• Verify the INCI names and CAS numbers against your own ingredient listing software or regulatory file.
• For the US market, do not rely on the EU allergen list alone. Ask for a complete qualitative formula or a statement that identifies any substances requiring separate attention under FDA or state rules.

A written fragrance supplier’s conformity statement can support your documentation, but it is not a substitute for your own legal review. Treat it as evidence, not as a certificate.

What to ask the factory for an allergen declaration

Before you place a fragrance oil order, send a clear specification to the factory or your sourcing partner. The following questions will help you get useful documentation:

• Please provide a written allergen declaration for this exact fragrance oil, stating whether each substance on the current EU Annex III list is present and, if so, the percentage by weight.
• Does this declaration apply to the current product version? What is the revision date?
• For the US market, can you confirm whether any fragrance components require additional labeling under FDA rules or state requirements such as Proposition 65?
• Can you provide supporting documentation, such as the fragrance supplier’s conformity statement or safety data sheet, for the specific formula?
• Will this declaration remain valid if the formulation changes, or will you notify us before shipment?

Also ask for the percentage of each allergen by weight, not just “present”, because EU thresholds depend on concentration. If the supplier gives only a range, ask whether the upper end crosses any threshold for your product type.

Request documentation for each SKU rather than accepting a blanket statement for a product family. Minor formula changes can affect the allergen profile. If a supplier hesitates to provide a written declaration for a specific product code, treat that as a sourcing risk.

In short, treat fragrance allergen documentation as part of your supplier qualification workflow, not as an afterthought. Ask for written data for each product version, map it to each destination market, and keep it on file for label rechecks.
