Assess exposure before designing a warning
Create a documented inventory of fragrance formula, raw materials, impurities, packaging inks and components, listed chemicals, concentrations, and foreseeable consumer use. Compare exposures with applicable safe-harbor levels and other legal considerations using qualified toxicology and counsel. Record the basis for warning or not warning. Do not ask the label supplier to decide whether a chemical creates a duty. The packaging project begins only after the responsible business has a controlled exposure conclusion.
Use current OEHHA warning rules
OEHHA's December 2024 rulemaking became effective 1 January 2025 and revises short-form safe-harbor content, including naming at least one chemical for each relevant endpoint in the new format. OEHHA provides a 3-year transition. Its business FAQ states products manufactured and labeled before 1 January 2028 may continue using the prior or new short-form content under the described safe-harbor treatment. Confirm current text, endpoint, chemical name, signal wording, symbol, URL, and any tailored-warning rule before production.
Fit the warning without compromising clarity
OEHHA states short-form warnings must be no smaller than 6-point type and may run over multiple lines. The warning symbol is generally placed to the left and no smaller than the height of the signal word. Exact requirements and exceptions should come from current official rules. Build a 1:1 proof on the immediate container or wrapper, preserving prominence and contrast. A QR code alone generally does not satisfy safe-harbor delivery when consumers must seek out the warning.
Coordinate package and ecommerce warnings
A physical warning and an online warning are separate delivery questions. OEHHA explains that consumers should receive the warning before purchase and provides rules for internet and catalog sales. Link each California SKU and warning revision to product pages, marketplace feeds, distributor data, carton artwork, and label inventory. A product image can support an online warning only when the chosen method satisfies current rules. Audit mobile checkout, not just the desktop product page.
Choose full-length, short-form, or tailored route carefully
The available safe-harbor route depends on exposure and whether a tailored warning applies. Short form is not a universal shortcut; OEHHA says it cannot replace a tailored warning unless the tailored regulation allows it. Full-length text needs more area but can provide a clearer statement. Ask counsel to approve exact content and manufacturing-date transition logic. Prototype 3 layout options if the perfume carton or bottle has limited space.
Control dates, inventory, and changes
Record formula assessment, chemical endpoint, warning route, approved copy, artwork code, manufacture and label dates, online version, and reviewer. Prevent old and new short-form artwork from mixing after the transition plan. Inspect 25 units and corresponding ecommerce records. Reassess after formula, supplier, packaging, exposure, chemical listing, safe-harbor level, OEHHA rule, market, or use changes. Check official OEHHA sources before every major reorder because this area has active transition timing.
Decision table
| Material or substrate route | Cost or price effect | Best-fit use or application scenario | Main risk |
|---|---|---|---|
| Full-length safe-harbor warning | More package area and review cost | Products where approved detailed content fits | Crowding or mismatched chemical text creates risk |
| Current short-form warning | Compact but still requires chemical and formatting controls | Small packages without a tailored warning route | Transition and endpoint details can be implemented incorrectly |
| Tailored warning | Application-specific review and artwork cost | Exposure categories governed by tailored regulations | Generic short form may not qualify |
| No warning after documented assessment | Assessment and record cost, no label area | Products shown not to require a warning under qualified review | Incomplete exposure data can invalidate the conclusion |
Execution steps
- Have qualified reviewers assess listed chemicals, exposure, safe-harbor levels, exemptions, packaging, and foreseeable use.
- Select the current full-length, short-form, or tailored route and approve exact symbol, signal, chemical, endpoint, URL, and language.
- Create 1:1 package proofs plus online and catalog delivery, then test visibility and pre-purchase presentation.
- Control manufacturing and labeling dates through the 2028 short-form transition, inspect 25 units, and recheck OEHHA before reorders.
WowSticker Practical Experience
WowSticker reproduces buyer-approved warning artwork and does not perform a Proposition 65 exposure assessment. Provide exact counsel-approved copy, symbol file, minimum type, finished dimensions, container and carton surfaces, manufacturing-date control, and revision code. Test 5 samples for print and adhesion and inspect a 25 units production set. The responsible business owns exposure analysis, chemical naming, warning route, online delivery, transition treatment, and ongoing legal review.
Final suitability for When Does California Fragrance Packaging Need a Prop 65 Warning depends on the submitted artwork, construction, application evidence, quantity, site, and buyer procedure.

- Required delivery time and transition timeline
- Target price range or compliance budget
- Approved chemical, endpoint, warning route, online delivery, and version controls
Frequently asked questions
Does every listed chemical require a warning?
No. Proposition 65 is exposure-based; qualified reviewers should assess exposure, safe-harbor levels, exemptions, and applicable rules.
Did short-form warnings change?
Yes. OEHHA amendments effective 1 January 2025 revise safe-harbor short-form content and provide a transition through products manufactured and labeled before 1 January 2028.
Can a short-form warning omit the chemical forever?
The revised safe-harbor short form names at least one chemical for each relevant endpoint; older content has limited transition treatment.
Can a QR code replace the package warning?
OEHHA guidance says a code that requires consumers to seek out the warning generally is not automatic safe-harbor delivery.
Must online shoppers also see a warning?
Applicable internet and catalog requirements must be addressed so consumers receive the warning before purchase.
When should the assessment be repeated?
Repeat after formula, supplier, impurity, packaging, exposure, chemical list, safe-harbor, OEHHA rule, market, or use changes.
