What Changed on January 1, 2026

Washington's ban was passed under the state's Safer Products for Washington law. Starting January 1, 2026, it is illegal to manufacture, sell, distribute, or use thermal paper containing any bisphenol chemical — including BPA, BPS, and their chemical relatives — within Washington State.

The limit is strict: receipt paper can contain no more than 200 parts per million (ppm) of bisphenol. In practice, that means any paper intentionally coated with a bisphenol developer is now prohibited.

The ban covers:

  • Cash register receipts
  • Printed tickets (parking, events, transit)
  • Thermal shipping labels
  • Any other thermal paper product where bisphenols are used as a print developer

Washington is the first U.S. state to take this step. The European Union banned BPA from thermal paper back in 2020, and the U.S. is now starting to follow suit, state by state.

Why Did Washington Do This?

The short version: bisphenols are hormone-disrupting chemicals, and thermal receipt paper is one of the most direct ways people absorb them into their bodies.

Unlike BPA in plastic bottles — where the chemical is chemically bonded into the plastic — in thermal paper, bisphenol sits as a free molecule on the surface of the paper. That means it rubs off onto skin easily every time someone handles a receipt.

Cashiers and retail workers are especially at risk. Studies have measured BPA absorption in cashiers at up to 71 micrograms per day from receipt handling alone. A 2023 study by the Ecology Center found bisphenols in 80% of receipt paper from major U.S. retailers.

Washington's Department of Ecology cited research linking bisphenol exposure to diabetes, obesity, high blood pressure, heart disease, infertility, and developmental harm in children and fetuses. The state also noted the environmental problem: bisphenol-coated receipts contaminate recycled paper, ending up in napkins, toilet paper, and food packaging.

Who Does This Law Affect?

The law applies to any business in Washington State that:

  • Issues printed receipts to customers
  • Uses thermal labels or tickets
  • Manufactures, sells, or distributes thermal paper products in Washington

That includes retailers, restaurants, coffee shops, gas stations, pharmacies, parking operators, event venues, and any other business that hands a customer a printed slip of thermal paper. It is worth noting that thermal paper appears in far more settings than most people realize — from hospital ECG printouts to airline boarding passes.

If you ship thermal paper products into Washington, the law applies to you even if your business is located elsewhere.

The Good News: Compliant Paper Already Exists

You don't need to redesign your point-of-sale system or buy new printers. Phenol-free thermal paper is widely available, works in standard thermal printers, and is competitively priced. There are several approved alternatives:

Pergafast 201 (urea-based developer) — The most common drop-in replacement. Widely available from paper suppliers, compatible with virtually all thermal receipt printers, and well-tested.

Blue4est technology — Uses a heat-activated coating that reveals an underlying dark layer without any chemical developer. No phenols, no bisphenols of any kind. Available from Appvion and used by a growing number of retailers.

Ascorbic acid (vitamin C) coatings — A newer alternative that uses ascorbic acid as the developer. Less widely distributed but available through specialty suppliers.

Digital/e-receipts — The simplest solution of all. If customers opt in to email or text receipts, you don't need to print anything. Several major retailers have moved this direction: Starbucks, Target, and Whole Foods, among others, have restricted bisphenol paper nationally ahead of the law.

When ordering replacement paper, look for products labeled "phenol-free" rather than just "BPA-free." A BPA-free label doesn't guarantee the paper is free of BPS or other bisphenols — it may just mean one bisphenol was swapped for another. "Phenol-free" or "no-phenols-added" is the label that confirms full compliance.

How to Know If Your Current Paper Is Compliant

Most thermal paper rolls are not labeled with their chemical composition. Here's how to check:

  1. Contact your paper supplier directly. Ask them to confirm whether your current stock is phenol-free. Reputable suppliers will have documentation.

  2. Look for "phenol-free," "BPA-free and BPS-free," or "no-phenols-added" on the packaging. "BPA-free" alone is not sufficient.

  3. Do the scratch test. Thermal paper coated with bisphenols typically turns black or dark when scratched hard with a fingernail. This is not foolproof, but it can indicate the presence of a reactive developer.

  4. Check with your POS system provider. Many POS hardware vendors now specify compatible phenol-free paper rolls for their equipment.

If you're unsure, switching to a certified phenol-free supplier is the safest route.

Financial Help for Washington Businesses

Washington State offers a Product Replacement Program through the Department of Ecology that provides financial support for small businesses transitioning away from toxic chemicals. Thermal receipts are an explicitly listed product category.

The program can help cover the cost of:

  • Replacing non-compliant paper stock
  • Upgrading point-of-sale equipment that may require compatible paper formats
  • Getting products certified as safer alternatives

Manufacturers also have access to a separate Safer Product Certification Subsidy Program, which reimburses the cost of third-party certification for compliant products. Small manufacturers (under 50 employees) can receive up to $30,000 in reimbursement.

What About California?

California is next. Assembly Bill 1604, introduced in January 2026 and authored by Assembly Member Catherine Stefani, would ban bisphenols from thermal receipts statewide on a two-step timeline:

  • January 1, 2027: BPA prohibited from all paper receipts
  • January 1, 2028: All bisphenols (including BPS) prohibited

As of spring 2026, the bill has passed the Assembly Committee on Environmental Safety and Toxic Materials (7–0) and the Judiciary Committee (12–0), and is moving through the Appropriations Committee. The trajectory looks strong.

California already has a related pressure point: BPA and BPS are listed on the state's Prop 65 registry as chemicals known to cause cancer, birth defects, or reproductive harm. California businesses using bisphenol-coated receipts without proper Prop 65 warning signage are already exposed to enforcement actions — and in 2025, there were a growing number of such actions filed against retail, food service, and hospitality businesses.

The practical takeaway: If you operate in both Washington and California, switching to phenol-free paper now puts you ahead of both laws.

The Bigger Trend: This Is Going National

Washington's ban is already rippling outward. Because major national retailers don't want to manage separate supply chains for one state, many have switched to bisphenol-free receipts everywhere. A 2026 survey by Toxic-Free Future found 18 of 46 major retailers had restricted bisphenols in their receipts nationally — including Costco, CVS, Home Depot, Target, Walgreens, Whole Foods, and Starbucks.

Toxic-Free Future's spokesperson noted: "This is making a difference not just in Washington state but across the country, because retailers are changing what they are doing everywhere to be in compliance here."

More states are watching. The legislative momentum around bisphenols in receipts is the strongest it has ever been. For business owners, the question is no longer whether to switch — it's when.

Your 5-Step Compliance Checklist

If your business is in Washington State (or you want to get ahead of California):

  1. Audit your current paper stock. Contact your supplier and ask specifically whether your thermal paper contains any bisphenol compounds, including BPS.

  2. Request phenol-free replacements. Ask for paper labeled "phenol-free" or "no-phenols-added." Confirm it is compatible with your printer model.

  3. Update your paper purchasing going forward. Make phenol-free a standard requirement in your supply orders.

  4. Consider offering digital receipts. Even offering customers a choice reduces paper use and eliminates the compliance question entirely.

  5. Check for state financial assistance. Washington businesses can apply through the Department of Ecology's Product Replacement Program to offset switching costs.

A Note on "BPA-Free" Labels

One important thing to understand: "BPA-free" does not mean bisphenol-free.

When BPA was first scrutinized, many paper manufacturers simply swapped it for BPS (bisphenol S) and continued printing "BPA-free" on their packaging. BPS raises similar health concerns — it has a nearly identical chemical structure to BPA and appears to behave similarly in the body. Washington's law bans the entire class of bisphenol chemicals, not just BPA.

This is sometimes called "regrettable substitution" — replacing one problematic chemical with a chemically similar cousin that causes the same problems. The only label that confirms genuine compliance is "phenol-free."
