Key points

What the buyer sees

On the product page the buyer sees a box with the symbol, signal word and text, or a link to the warning.

What the admin gets

On the product you switch the warning on, pick the wording and name the chemicals.

How much it costs

The base version is free. Pro costs 990 UAH for a one-year licence. A year of updates, technical support and all Pro features.

The trial starts when you ask

A fresh install is the free version, nothing switches on by itself. The “Try Pro for 7 days” button → e-mail → the key right in the window and by e-mail.

One key — a site and a staging copy

Moving the site? Unlink the licence on the old domain and activate it on the new one yourself. A staging copy (staging., dev.) works with the same key and does not take a site slot. For studios — keys for 5 or 25 sites, or unlimited.

Technical requirements

  • WordPress 6.2+, WooCommerce 8.0+, PHP 7.4+.
  • Special cases of section 25607 (alcohol, furniture, car parts) go only through custom text, which the plugin does not check.

Full module description

Prop 65 Warnings helps you show the Proposition 65 warning to the buyers who need it: on the product page, in the cart and at checkout. A buyer outside California does not see it, and the order keeps a record of what was shown.

This is not legal advice. The plugin shows the warning you chose. Whether a product needs one, which wording fits and which chemicals to name are for you to decide with your supplier or a California lawyer.

What the buyer sees

On the product page the buyer sees a box with the symbol, signal word and text, or a link to the warning. The same appears in the cart and at checkout before the button, with the product name. If the address is unknown, matches a typical shop location or the order is local pickup, the warning shows.

What the admin gets

On the product you switch the warning on, pick the wording and name the chemicals. The text is not translated on purpose: it is a verbatim quote. A separate list shows incomplete warnings.

The order keeps the text that was really on the page. An express button or a theme without the needed hook gives Not confirmed rather than a false Displayed. In Pro a rule can cover a category.

How it works, step by step

  1. You mark a product and pick the wording.
  2. The buyer sees the warning on the product page.
  3. The plugin checks the delivery state.
  4. Cart and checkout show the warning if California is possible.
  5. The shown text is recorded on the order.

Under the hood

  • The warning hides only when the destination is surely outside California.
  • A page that differs from the anonymous one goes without cache.
  • The warning text does not pass through translation.
  • A rule change needs a new release.

How to install

  1. Plugins → Add New → Upload Plugin: pick the zip and activate.
  2. WooCommerce → Prop 65 Warnings: pick the mode and signal word.
  3. On the product tab switch the warning on and pick the wording.
  4. For Pro: paste the key or start the 7-day trial.

The module is not on wordpress.org yet: the free version and Pro are one archive from this page. Without a key it works as the free version.

@catcode_support Setup, compatibility, activation
Does the plugin shield me from claims?

No. It only shows the text you chose. You decide about the product and the wording.

Why is the text in English?

The wording is a verbatim quote of the regulation, so the plugin does not translate it.

Will a buyer from another state see the warning?

Only while the state is unknown. Once the address is surely outside California, the warning hides.

Does it work on the block checkout?

Yes, and on the classic one too.

Is there one for OpenCart?

Yes, it is a separate module.
