Hawaii’s Sunscreen Law and What You Can Actually Pack

You will not be fined for wearing sunscreen in Hawaii, and airport security will not take it out of your bag. Hawaii’s sunscreen law stops stores from selling two specific chemicals, and a couple of islands go further and only sell the mineral kind. It does not ban you from bringing or wearing what you already own. The simplest fix for the whole trip is to pack mineral sunscreen, the kind whose active ingredient is zinc oxide or titanium dioxide, and you are fine on every island. This guide explains exactly what is restricted, the rules island by island, what to buy, and why a viral claim about a new 2026 ban is wrong.

Last updated 6 July 2026. This is general information for visitors, not legal advice. Laws can change, so confirm current rules with the county if you need certainty.

Quick answer

Hawaii’s statewide law bans stores from selling sunscreen with two chemicals, oxybenzone and octinoxate. It has been in force since January 2021.
It is a sales ban on shops, not a ban on wearing sunscreen. Visitors are not fined, and you can bring and use your own.
Maui goes furthest and allows only mineral sunscreen to be sold or used. The Big Island allows only mineral sunscreen to be sold, but does not restrict what you use.
Oahu and Kauai follow only the statewide two-chemical rule.
The simplest choice everywhere is mineral sunscreen with non-nano zinc oxide or titanium dioxide. Buy it before you fly, where it is cheaper and easier to find.
Hawaii did not add a six-chemical ban in 2026, despite what you may have read. Only the two chemicals are restricted statewide.

What Hawaii’s sunscreen law actually bans

The statewide law, in force since 1 January 2021, made Hawaii the first US state to restrict reef-harming sunscreen chemicals. It bans the sale and distribution of any sunscreen containing oxybenzone or octinoxate without a prescription. Those are the only two chemicals restricted statewide, as of July 2026.

The single most misunderstood thing about this law is who it applies to. It is a rule for stores, not for beachgoers. Shops in Hawaii cannot sell the banned products, but nothing in the statewide law stops you from bringing your own sunscreen or wearing it on the beach. There is no airport inspection, no beach patrol checking your bottle, and no fine for a visitor who applies whatever they packed. If you already own sunscreen, you can bring it. The counties of Maui and the Big Island add stricter rules about what can be sold, which is where the details below matter.

The sunscreen rules island by island

There are really three layers of rules, and which islands you visit decides what applies to you.

Where you are	What the rule restricts	Can you bring and wear your own?
Statewide (all islands)	Stores cannot sell sunscreen with oxybenzone or octinoxate	Yes. Bring and wear anything you like; only sales are restricted.
Oahu and Kauai	Only the statewide rule. Chemical sunscreens without those two ingredients are still sold and legal	Yes.
Big Island (Hawaii County)	Stores can sell only mineral sunscreen. But use is not restricted	Yes. You can bring and use chemical sunscreen here, you just cannot buy it on the island.
Maui County	The strictest. Only mineral sunscreen may be sold, distributed, or used	Bring mineral sunscreen. Using non-mineral is prohibited, though enforcement is education-first and no visitor has been reported fined.

Only two chemicals are banned statewide: oxybenzone and octinoxate. Maui and the Big Island are broader, allowing only mineral sunscreen, meaning products whose active ingredient is zinc oxide or titanium dioxide. The penalties in the county ordinances are aimed at the stores that sell banned products, not at visitors on the sand. If your trip includes Maui, the safe move is to arrive with mineral sunscreen, because you cannot rely on buying anything else there and using non-mineral is against the county rule.

Hawaii did not ban six chemicals in 2026

Hawaii has not banned octocrylene, homosalate, octisalate, or avobenzone. The statewide law bans only two chemicals, oxybenzone and octinoxate, and that has not changed. You may have seen claims online, some of them repeated by search-engine summaries, that a new six-chemical ban took effect in 2026. That is not accurate. No such statewide ban has been enacted. Bills to add more chemicals to the list have been introduced in past legislative sessions and none has become law. The confusion usually comes from mixing up Maui County’s mineral-only rule, which effectively rules out many chemical ingredients on that island, with the statewide law, which still restricts only the original two.

What sunscreen to pack for Hawaii

Here is the practical version. If you want one answer that works for the whole family on every island, buy mineral sunscreen with non-nano zinc oxide or titanium dioxide, and you are compliant everywhere and best for the reef. Pack enough for the trip, because it is cheaper and comes in more choices on the mainland than at a Hawaii resort shop.

How to read the label

Ignore the words on the front. “Reef-safe” and “reef-friendly” mean nothing legally and are not checked by anyone. A bottle can say “reef-safe” and still contain a banned chemical.
Flip it over and read the active ingredients. For a mineral sunscreen, the only active ingredients should be zinc oxide, titanium dioxide, or both.
Look for “non-nano.” This is the reef-friendlier form and it is what Maui’s rule specifically requires.
Avoid these two names anywhere in the ingredients: oxybenzone and octinoxate.

A few common questions clear up fast. Spray sunscreen is not banned as a format, so a mineral spray is fine, though sprays waste a lot of product into the air and sand and some parks discourage them. Kids’ and baby sunscreens are often already mineral, which makes them easy, and there is no separate rule for children, so the same mineral guidance covers the whole family. And you do not need to throw away the chemical sunscreen you already own. You can bring it and wear it on Oahu, Kauai, and the Big Island. Just pack mineral for the Maui portion of your trip.

What reef-safe really means on a label

It is worth being blunt about this, because the marketing is designed to reassure you rather than inform you. “Reef-safe” and “reef-friendly” have no legal or regulatory definition in Hawaii or under US law. Any manufacturer can print those words on any bottle. The only thing that actually determines whether a sunscreen is legal to sell in Hawaii, and kinder to the reef, is the active-ingredient panel on the back. Mineral sunscreen with non-nano zinc oxide or titanium dioxide is the compliant, lower-impact choice. It is not proven harmless to coral, since even zinc has shown some toxicity to coral in laboratory studies and the nano form is the bigger concern, but it avoids the two banned chemicals and, in non-nano form, is the lowest-impact option widely available.

Why Hawaii restricts these chemicals

Hawaii’s reefs are genuinely under stress, but it is worth being clear-eyed about why. The main driver of the mass coral bleaching Hawaii has suffered is ocean warming, a climate problem, not sunscreen. What laboratory and localized field studies have shown is that oxybenzone and octinoxate can harm coral at the concentrations that build up around busy snorkel and swim spots, where thousands of people apply sunscreen every day. How much damage that causes in the open ocean is still debated among scientists. Lawmakers took a precautionary step: at popular reefs, cutting out two chemicals we already have alternatives for is a cheap, sensible way to remove one avoidable stressor. Switching your sunscreen is a good thing to do, but it is not what saves the reef.

What you do in the water matters more than which bottle you buy. Never touch, stand on, or kick the coral, because a single careless fin kick can break decades of growth, and it can also bring a fine, as our guide to Hawaii’s wildlife and reef fines explains. Wearing a rash guard or a UV swim shirt is the single best move, because it protects your skin better than any lotion and means far less sunscreen washes off into the water in the first place. Then you only need sunscreen on your face, hands, and feet. If you are snorkeling rocky reefs, our guide to reef and coral safety covers protecting both the reef and your feet, and Hawaii’s public beaches guide covers where you will actually be swimming. The sunscreen rule is one of several new Hawaii tourist rules worth knowing before you go.

Frequently asked questions

Is sunscreen banned in Hawaii?

Not for you to wear. Hawaii bans stores from selling sunscreen that contains two chemicals, oxybenzone and octinoxate, but it does not ban visitors from bringing or wearing their own sunscreen. Maui and the Big Island only sell mineral sunscreen, and Maui also restricts using non-mineral products, but there is no statewide ban on wearing sunscreen.

What sunscreen is banned in Hawaii?

Statewide, stores cannot sell sunscreen containing oxybenzone or octinoxate. Those are the only two chemicals restricted across all islands. On Maui and the Big Island, stores can sell only mineral sunscreen, so chemical sunscreens generally are not sold there, but that is a county sales rule, not the statewide ban.

Can I bring my own sunscreen to Hawaii?

Yes. Pack whatever you already own. The law restricts what stores can sell, not what you can carry or wear, so there is no airport check and no fine for bringing your own. If your trip includes Maui, bring mineral sunscreen for that part, since using non-mineral is against the county rule there.

Did Hawaii ban six sunscreen chemicals in 2026?

No. Hawaii has not banned octocrylene, homosalate, octisalate, or avobenzone. The statewide law still restricts only oxybenzone and octinoxate, and that has not changed in 2026. Claims of a new six-chemical ban circulating online are inaccurate, and no bill expanding the list has become law.

Will I get fined for wearing banned sunscreen in Hawaii?

No. The statewide law and the Big Island ordinance penalize stores that sell the banned products, not visitors who wear them. Maui County’s rule does prohibit using non-mineral sunscreen, but enforcement is education-first and there are no reported cases of visitors being fined for what they wore on the beach.

Is the sunscreen ban statewide or only on certain islands?

Both. The two-chemical sales ban is statewide. Maui and the Big Island add stricter mineral-only sales rules, and Maui also restricts use. Oahu and Kauai follow only the statewide rule, so chemical sunscreens without the two banned ingredients are still sold and legal there.

What sunscreen can I use on Maui?

Mineral sunscreen, meaning a product whose active ingredient is zinc oxide or titanium dioxide, ideally non-nano. Maui County allows only mineral sunscreen to be sold or used, so bring a mineral product with you, because you cannot count on buying anything else on the island.

Do I need mineral sunscreen for the Big Island?

You can bring and wear chemical sunscreen on the Big Island, because the county restricts only sales, not use. But stores there sell only mineral sunscreen, so if you expect to buy sunscreen once you arrive, plan on mineral, or pack enough of your own.

Is chemical sunscreen legal on Oahu and Kauai?

Yes, as long as it does not contain oxybenzone or octinoxate. Oahu and Kauai follow only the statewide rule, so chemical sunscreens using other filters, such as avobenzone, are sold and legal there. Mineral sunscreen is still the reef-friendlier choice.

What does reef-safe sunscreen actually mean?

Legally, nothing. “Reef-safe” and “reef-friendly” are marketing terms with no regulated definition, and no one checks them, so a bottle can carry those words and still contain a banned chemical. Ignore the front of the bottle and read the active ingredients on the back instead.

What ingredients should Hawaii-legal sunscreen have?

Look for mineral sunscreen whose only active ingredients are non-nano zinc oxide, titanium dioxide, or both. That is compliant on every island, including Maui, and is the lower-impact choice for the reef. Avoid oxybenzone and octinoxate anywhere in the ingredient list.

Where can I buy reef-safe sunscreen in Hawaii?

Mineral sunscreen is widely sold at Hawaii shops, drugstores, and resort stores, and on Maui and the Big Island it is the only kind sold. It tends to cost more and come in fewer choices than on the mainland, so buying before you fly is usually cheaper and easier. Read the label for zinc oxide or titanium dioxide rather than trusting a “reef-safe” claim.

Is avobenzone banned in Hawaii?

No. Avobenzone is not part of Hawaii’s statewide ban, which covers only oxybenzone and octinoxate, so a chemical sunscreen using avobenzone is legal to sell and wear on Oahu and Kauai. On Maui and the Big Island, however, only mineral sunscreen is sold, so an avobenzone product would not be on the shelves there.
