Launching a private label sunscreen stick can feel like a product decision: pick the SPF, choose the stick format, and you are ready to order. In practice, packaging and labeling are where most first-time sunscreen projects stall, because a single wording error can turn a finished product into one that cannot legally ship. An SPF 40 mineral stick sold into the United States and the European Union carries two different rulebooks, and the claim that sounds best on a carton — “waterproof” or “sweatproof” — is often the one a regulator will not let you print.
This guide walks through, at a buyer level, how to label and package an SPF 40 mineral sunscreen stick for both markets, drawn from our OEM mineral sunscreen face stick and the standards that govern it.
A sunscreen label is not marketing copy the way a lotion label can be. In the United States, a sunscreen is an over-the-counter drug, so the label is a regulated document with required panels and wording. In the European Union it is a cosmetic, but the cosmetic labeling rules are strict and specific, and they do not map one-for-one onto US requirements. The moment you decide to sell one stick in both regions, you are managing two compliance files, not one.
Packaging does more than look good on a shelf. UV filters and the emulsions that carry them degrade with heat, light, and oxygen over time, so the primary stick body and its cap must give the formula a stable, protected home from the factory floor to the customer’s bag. Secondary packaging — the carton the stick sits in — is what protects the product in transit and gives you the printable surface where the legally required information lives.
Getting this right early saves real money. Reprinting cartons, relabeling stock, or diverting a container because of one prohibited word is far more expensive than building the label to specification before you commit to volume. The good news is that a mineral sunscreen stick, especially one that already ships carton-packed with an 80-minute water-resistance claim, starts from a well-understood baseline that both markets recognize.
In the US, sunscreen is regulated under the over-the-counter drug monograph, 21 CFR Part 352, published and maintained by the US Food and Drug Administration. That means the primary information panel must be the standard “Drug Facts” box, not a free-form design.
The Drug Facts panel has to contain, at minimum:
The SPF number on the panel must match the value you actually substantiated through standardized testing. For this stick that is SPF 40, which the panel prints as “SPF 40” (the “+” notation is reserved for the highest tier, SPF 50+). A “Broad Spectrum” claim is only permitted if the UVA protection meets the FDA’s critical-wavelength criterion, so if the formula clears that test you can add it, and if it does not you should not.
Water-resistance wording is the area where the most labels go wrong. The US allows “water resistant: 40 minutes” or “water resistant: 80 minutes.” It does not allow “waterproof,” “sweatproof,” “sunblock,” or “re-waterproof.” It is common to see a supplier’s product title still carrying “waterproof / sweat resistant” as a marketing shorthand, but the words actually printed on the carton and the Drug Facts panel must read “water resistant: 80 minutes.” That distinction is the single most frequent correction in a sunscreen label review.
Finally, the choice of filters matters for compliance durability. Zinc oxide and titanium dioxide are the established physical (mineral) actives in the OTC sunscreen monograph, and the FDA’s 2024 sunscreen final rule left these mineral filters in place while it reclassified several of the older chemical filters. For a brand that wants a clean, defensible label, a mineral stick is a practical starting point.
The EU treats sunscreen as a cosmetic under the Cosmetic Products Regulation (EC) No 1223/2009, so there is no Drug Facts box. Instead, the label must carry a defined set of cosmetic labeling elements. The full text of the regulation is published by the European Commission, and the practical labeling list follows:
For the sun-protection claim itself, the EU expects the SPF value to be determined by recognized test methods (the ISO 24444 in-vivo / ISO 24443 in-vivo family of standards), published by ISO. You print SPF 40, and because the EU also expects a statement of UVA protection, you pair it with a UVA claim (the PA category or an explicit UVA statement) and ensure the UVA-to-UVB ratio meets the “one-third of the nominal SPF” benchmark. SPF 40 sits in the EU’s “high” protection band (SPF 30–50), which is useful positioning language for a serious daily-protection stick.
Two EU-specific points worth flagging for a mineral stick. First, the EU does not permit the word “waterproof”; a “water resistant” description is allowed only where it is substantiated, and it is usually kept simpler than the US minute-based claim. Second, if a nano form of zinc oxide or titanium dioxide were used, the ingredient list would need to add “(nano)” to that entry — a non-nano mineral stick typically avoids that note entirely, which keeps the label cleaner.
The fastest way to avoid a rejected label is to keep a single source of truth for every claim, and to know which side of each market’s line you are standing on. The table below is the practical version of that for a 40-mineral stick.
| Claim | US (FDA) | EU (cosmetic) |
|---|---|---|
| SPF value | Print tested value, e.g. “SPF 40” | Print tested value, e.g. “SPF 40” |
| Water resistance | “Water resistant: 80 minutes” (must be tested) | “Water resistant” if substantiated; no minute claim |
| “Waterproof” | Prohibited | Not permitted |
| “Sweatproof” | Prohibited | Not used |
| “Sunblock” | Prohibited (use “sunscreen”) | Not used |
| Broad spectrum / UVA | Allowed if UVA criterion met | UVA claim + UVA/UVB ≥ 1/3 of SPF |
Two principles follow from that table. First, never print a claim higher than the one you tested. If you tested 80-minute water resistance, you can say 80 minutes; if you only tested 40, you say 40. Second, reconcile the two regions on one label set if you intend to stock one carton design. Where a wording cannot satisfy both, the cleanest approach is region-specific cartons or a common label that keeps the more conservative claim, with a market-specific insert where needed.
On usage, both regions expect a reminder that sunscreen is one part of sun protection, not the only one, and that it should be applied generously and reapplied. Keeping that guidance consistent with the American Academy of Dermatology guidance is a sensible, defensible baseline for the Directions text.
The stick is really two packaging jobs in one: a primary container that keeps the formula stable, and a secondary carton that carries the compliance print and protects the stick in the supply chain.
The primary side is the stick body, the cap, and the twist mechanism. These are typically a rigid, light-blocking resin. Light-blocking and oxygen-limiting matter because both the mineral filters and the emulsion around them are more stable when sealed off from UV and air. Heat is the quiet enemy of a solid stick: in a hot car or a summer warehouse a softening point is reached where the stick can deform, so the material choice and a heat-stable formula work together.
The secondary side is the carton the stick ships in, and it is where most of your legal text lives. A carton gives you the print surface for the Drug Facts panel (US) or the full cosmetic label (EU), the barcode, and the retail shelf presence. Because the reference stick is already carton-packed, you are starting from a format that retail buyers and importers expect, and that protects the stick through cross-border freight. If you are building a broader sun line around this stick, the Sunscreen collection is a useful map of the formats that share the same labeling baseline.
A useful way to think about the components is as a small specification table:
| Component | Function | Compliance / practical note |
|---|---|---|
| Stick body (resin) | Holds the formula, blocks light & oxygen | Light-blocking, heat-stable resin preferred |
| Cap / twist mechanism | Seals, controls dosing, transit security | Child-safe not typically required for adult sunscreen sticks |
| Primary label / panel | Carries Drug Facts (US) or cosmetic label (EU) | Where prohibited-term corrections matter most |
| Carton (secondary) | Retail surface, barcode, transit protection | FSC / recyclable options available |
| Inner liner / wrap | Moisture & scuff protection | Optional; keeps stick pristine in the carton |
If you are building a brand around sensitive-skin positioning, note that a physical (mineral) stick with a clean, recyclable carton aligns well with the messaging buyers increasingly want, and it can be customized for specific markets.
One of the under-appreciated advantages of the stick format is logistics. A sunscreen stick is a solid, so it ships as general, non-hazardous cargo by both air and sea. No dangerous-goods classification, no special packaging, no airline volume restrictions on the unit itself.
Contrast that with a sunscreen spray, which is an aerosol and falls under UN Class 2 dangerous goods. Aerosols face limited air carriage, special packaging, dangerous-goods documentation, and higher shipping cost. If your plan is to move volume quickly or to ship internationally, the stick sidesteps that entire category of friction, which is a real reason brands choose the stick format alongside the consumer convenience.
That said, “general cargo” still needs care in the details. Heat is the main risk, so avoid leaving cartons in unrefrigerated containers during peak summer or in hot-weather transshipment hubs. Carton stacking strength should be confirmed for the case size you plan to ship. And keep your documentation set ready per market: commercial invoice, the COA (certificate of analysis) and MSDS the product is documented with, plus any certificates the destination market expects. For a brand exporting into the EU, the responsible-person documentation sits alongside the physical goods and must be in place before the product lands.
Secondary packaging is one of the first things a modern beauty or grocery buyer asks about, and it is a place where a mineral stick can be positioned well. The practical options to raise with your OEM partner include:
None of these options changes the regulatory label; they change the sustainability story around it. The key is to confirm what each option adds to the unit cost and to align it with the market you are entering first, because eco-packaging expectations and cost tolerance differ by region and by channel. Where a buyer requires a specific eco-claim, build it into the design proofing stage rather than after the carton is printed, so the claim and the material actually match.
Use this list before you hand a carton design to print. It folds the two rulebooks into one working sheet. For a buyer, keeping the responsible-person and testing documentation organized early is what the About Us page describes as part of the end-to-end OEM/ODM service, so it is worth building the habit at the concept stage.
Both markets
US specific
EU specific
Running this checklist against a single design, before print, is the cheapest compliance step in the whole process, and it is the one that prevents the most costly rework.
It depends on the market. In the United States a sunscreen is an over-the-counter drug and carries a Drug Facts panel. In the European Union the same product is a cosmetic regulated under the cosmetic regulation. One stick, two classifications, two labels.
Not for compliant labeling. In the US the correct, test-backed wording is “water resistant: 80 minutes,” and in the EU “water resistant” is allowed only where substantiated. “Waterproof” and “sweatproof” are prohibited or not permitted, so keep them out of the printed label even if they appear in a marketing title.
Zinc oxide and titanium dioxide are the established physical (mineral) actives in the US OTC sunscreen monograph, and the FDA’s 2024 final rule kept them in place while reclassifying several older chemical filters. A mineral stick is therefore a clean, defensible starting point for a label, and it suits sensitive-skin positioning. Specific formulation choices remain subject to your formulation and testing.
Yes, for retail and cross-border shipping. The carton is your secondary packaging: it carries the required print surface and barcode, protects the solid stick in transit, and is the format buyers and importers expect. The reference stick already ships carton-packed.
A solid stick ships as general, non-hazardous cargo by air and sea, which is a major advantage over aerosol sunscreen sprays that are classified as dangerous goods and face air-carriage limits.
