AB 1604 tackles chemical exposure from paper receipts by removing intentionally added bisphenols from the paper proofs of purchase consumers receive at the point of sale. The measure targets the material used to make receipts rather than the point‑of‑sale process, and it directs manufacturers to choose the least toxic replacements while blocking certain hazardous substitutes.
The bill is a product‑safety intervention with supply‑chain effects: it forces changes at the paper‑manufacturing level, creates compliance duties for businesses that hand out receipts, and gives state enforcement agencies tools to impose civil penalties and collect funds for enforcement. For compliance officers, the practical questions will be supplier certifications, substitution reviews, and proof that replacements meet the statute’s least‑toxic standard.
At a Glance
What It Does
The bill prohibits intentionally added bisphenol A first and then expands to ban all intentionally added bisphenols in paper proofs of purchase; it authorizes the Department of Toxic Substances Control to adopt implementing regulations and requires manufacturers to favor the least toxic alternatives while barring certain hazardous replacements.
Who It Affects
Paper manufacturers that produce receipt stock, converters and printers who supply retailers, and any business that issues paper receipts at the point of sale (with statutory exclusions for specified healthcare providers and small nonprofits).
Why It Matters
By focusing on the paper itself, the law shifts remediation upstream to material suppliers and raises the regulatory bar for chemical substitution—creating compliance work for procurement, product safety reviews, and possible shifts to electronic receipts.

What This Bill Actually Does
AB 1604 creates a targeted ban on intentionally added bisphenols in paper proofs of purchase. It defines key terms (for example, 'proof of purchase' is a paper receipt provided at the point of sale and 'manufacturer' is the company that makes the paper) and establishes a two‑step phase‑out: first removing intentionally added bisphenol A from paper receipts, then expanding the prohibition to all intentionally added bisphenols.
The statute’s focus is the chemical composition of the paper produced for use as receipts, not the act of issuing a receipt itself.
The bill gives the Department of Toxic Substances Control (DTSC) authority to write implementing regulations and to post enforcement actions on its website. Enforcement is vested in DTSC and several public prosecuting offices; violations carry civil penalties and collected penalties must be deposited into the Toxic Substances Control Account for DTSC use upon appropriation.
The statute also creates a fee‑shifting element: a prevailing plaintiff who establishes a violation is entitled to reasonable attorney’s fees and costs.On substitution, AB 1604 requires manufacturers to choose the least toxic alternative when they remove a bisphenol. It explicitly forbids replacing bisphenols with chemicals the U.S. EPA classifies as carcinogenic (or likely carcinogenic or with suggestive evidence), with chemicals listed under California’s Proposition 65 as causing cancer or reproductive harm, with reproductive toxicants identified by EPA or listed under Proposition 65, or with chemicals DTSC has designated as Candidate Chemicals.
That combination of rules is designed to reduce the chance of a “regrettable substitution” where a banned chemical is replaced with one that poses equal or greater hazards.Practically speaking, covered entities will need new supplier certifications, updated material specifications for receipt stock, and internal procedures to assess and document replacement choices against the least‑toxic standard. Because the law defines 'manufacturer' narrowly as the paper maker, companies further down the chain—retailers and POS vendors—must rely on upstream compliance evidence from paper suppliers, converters, or their distributors.
The statute leaves open how DTSC will operationalize 'least toxic' and how testing, sampling, or traceability will be required, which are key implementation tasks the department will likely address in regulations.
The Five Things You Need to Know
The statute phases the ban: it bars intentionally added bisphenol A in paper proofs of purchase first, then bans all intentionally added bisphenols the following year.
Civil penalties are capped at $5,000 for a first violation and $10,000 for each subsequent violation; collected penalties are routed to the Toxic Substances Control Account for DTSC use upon appropriation.
Enforcement may be brought by DTSC, the Attorney General, a district attorney, a county counsel, or a city attorney; a prevailing plaintiff who proves a violation can recover reasonable attorney’s fees and costs.
The bill requires manufacturers to select the least toxic alternative when replacing bisphenols and prohibits substitution with chemicals classified by EPA as carcinogenic (or likely/suggestive), chemicals listed under California’s Prop 65 for cancer or reproductive harm, and any chemical DTSC has identified as a Candidate Chemical.
The statutory definitions narrow scope: 'manufacturer' means the paper maker (not necessarily the retailer), and 'business' includes most entities accepting cash, credit, or debit but explicitly excludes healthcare providers and nonprofit institutions with under $2 million in gross receipts.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Who and what the law covers
This section sets the statutory vocabulary. 'Bisphenol' is described structurally (two phenol rings linked by a single atom), 'proof of purchase' is limited to paper receipts provided at point of sale, and 'manufacturer' is the entity that makes the receipt paper. That allocation matters because liability and compliance obligations are placed primarily on the paper maker; downstream actors (retailers, printers) must rely on supplier assurances rather than being the primary target of the ban. The 'business' definition clarifies excluded entities—healthcare providers and small nonprofits under $2 million—so compliance screening should include revenue tests for nonprofit suppliers and customers.
Phased prohibition, DTSC rulemaking, and penalty framework
This provision phases in the ban (BPA first, then all bisphenols), authorizes DTSC to adopt implementing regulations, requires the department to publish violations on its website, and specifies enforcement authorities and penalty caps. By combining administrative rulemaking authority with public posting, the law creates both regulatory and reputational pressure on violators. The civil penalty ceiling structure (one amount for first, a higher amount for repeat violations) incentivizes early compliance; the requirement that penalties flow back to DTSC gives the enforcement agency a funding source for program activity, subject to appropriation.
How manufacturers must choose replacements
This section imposes a substantive substitution discipline: manufacturers must select the least toxic alternative and they may not replace bisphenols with chemicals EPA classifies as carcinogenic (or likely/suggestive), chemicals listed under California’s Safe Drinking Water and Toxic Enforcement Act (Prop 65) for cancer or reproductive toxicity, reproductive toxicants identified by EPA, or DTSC Candidate Chemicals. That list mixes federal and state hazard classifications and gives DTSC an explicit role in disallowing specific replacements—meaning manufacturers must run hazard assessments, track regulatory lists, and document selection decisions to show they met the least‑toxic duty.
Regulatory lists and the practical bar on regrettable substitutions
Though placed adjacent to the least‑toxic mandate, this subsection operationalizes the ban on particular classes of substitutes by referencing EPA classifications, Proposition 65 listings, and DTSC’s Candidate Chemical list. In practice, manufacturers will need to compare potential substitutes against those lists and may have to support exclusionary decisions with toxicological data. The cross‑referenced lists are dynamic; manufacturers will face ongoing diligence obligations as EPA, Prop 65, and DTSC lists change.
No preemption of other legal duties
The statute explicitly states its requirements are cumulative with other laws and do not relieve parties of other obligations. That language preserves existing duties under federal and state product‑safety, labeling, and toxics control regimes and signals that compliance counsel must evaluate AB 1604 alongside, not instead of, laws such as Proposition 65, DTSC regulatory programs, and any sector‑specific rules affecting thermal papers.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Retail workers — the bill reduces occupational exposure to bisphenols by targeting the receipt material they handle repeatedly, which should lower dermal exposure risks over time.
- Consumers concerned about chemical exposure — by removing intentionally added bisphenols from receipt stock, the legislation reduces a common everyday contact pathway, particularly for parents and people with frequent retail interactions.
- Recycling stream quality advocates and paper recyclers — eliminating bisphenols in receipt paper can reduce contamination of mixed paper bales, improving recyclability and lowering downstream treatment costs.
- Manufacturers of safer receipt technologies and digital‑receipt providers — the law creates demand for certified bisphenol‑free papers, alternative thermal chemistries, and electronic receipt solutions.
- State regulators and public health programs — collected penalties fund DTSC activities (upon appropriation), potentially strengthening enforcement capacity and monitoring.
Who Bears the Cost
- Thermal and specialty paper manufacturers — they must reformulate coatings, conduct hazard assessments for substitutes, and provide documentation that replacements meet the least‑toxic standard.
- Retailers and point‑of‑sale integrators — even though the statute targets paper makers, retailers will face procurement shifts, possible higher costs for compliant paper stock, and the administrative burden of securing supplier certifications.
- Converters, printers, and distributors of receipt stock — entities that convert base paper into receipt rolls or add coatings may need to modify processes, invest in new supply lines, and manage inventory turnover.
- DTSC and enforcement offices — while penalties are deposited to DTSC’s account, the department and local prosecutors will incur administrative and technical costs for testing, rulemaking, and enforcement that may exceed short‑term appropriations.
- Small suppliers near the nonprofit threshold — organizations just above the $2 million exclusion may face compliance costs that strain margins; the revenue cutoff also incentivizes careful monitoring of organizational structure and sales reporting.
Key Issues
The Core Tension
The bill balances protecting public health from endocrine‑disrupting bisphenols against imposing upstream manufacturing costs and compliance uncertainty; speeding a ban reduces exposure quickly but raises the likelihood of rushed substitutions or regulatory disputes unless DTSC issues clear, evidence‑based rules about what counts as the 'least toxic' replacement and how compliance will be verified.
AB 1604 seeks a straightforward removal of intentionally added bisphenols from receipt stock, but the statute leaves several implementation points undefined. 'Intentionally added' and 'least toxic alternative' are legal standards that require operational definitions and test methods; without clear analytical thresholds (for example, a practical quantitation limit), regulated parties and DTSC will need to develop sampling, lab methods, and chain‑of‑custody protocols in regulation or litigation. The law’s narrow definition of 'manufacturer' places legal responsibility on paper producers, but real‑world supply chains include converters, coaters, and printers—disputes are likely over which party must certify compliance and who bears recall or replacement costs for noncompliant rolls in circulation.
The substitution rules attempt to prevent regrettable replacements by cross‑referencing EPA hazard classifications, California’s Prop 65, and DTSC’s Candidate Chemical list. That approach reduces some substitution risk but creates a compliance burden: manufacturers must monitor evolving lists and justify their choices under a least‑toxic standard that the statute does not define.
The statute further creates enforcement complexity: it authorizes public enforcement by multiple offices and allows fee recovery for a 'prevailing plaintiff' but does not expressly create a private right of action, leaving open questions about standing and who may sue. Finally, the exclusion for small nonprofits and healthcare providers narrows the law’s reach but also creates potential gamesmanship at the margins and administrative friction as entities and regulators verify exemptions.
