California’s SB 343 recycling label rules make it illegal to put a chasing arrows symbol, a “please recycle” message, or any similar recyclability claim on a product or its packaging unless the material is actually collected and processed by California’s mainstream recycling system. The compliance deadline is October 4, 2026. After that date, any product sold, distributed, or imported into California carrying a recyclability claim is presumed to be making a deceptive statement unless the brand can prove the material clears specific infrastructure thresholds.1California Legislative Information. California Public Resources Code PRC 42355.51
The Deadline and Who Has to Comply
SB 343 was signed in 2021, but the labeling restrictions were timed to take effect 18 months after CalRecycle published its Material Characterization Study. That study came out on April 4, 2025, locking the compliance date at October 4, 2026.2CalRecycle. SB 343 Material Characterization Study Final Findings There is no grace period and no phased rollout. Products on store shelves after that date must already be compliant.
The law contains no exemptions. Size of company, product category, and annual revenue are irrelevant. A single-product small business faces the same rules as a multinational, and the obligations attach to anyone who offers for sale, sells, distributes, or imports a product or packaging bearing a recyclability claim in California.1California Legislative Information. California Public Resources Code PRC 42355.51
What Counts as Recyclable Under the Law
A material qualifies only if it passes two separate infrastructure thresholds. First, it has to be collected for recycling by programs serving jurisdictions that cover at least 60 percent of California’s population. Second, it has to be sorted into defined recycling streams by large-volume processing facilities that together serve at least 60 percent of recycling programs statewide.1California Legislative Information. California Public Resources Code PRC 42355.51
Even clearing both thresholds is not enough. The material also has to routinely become feedstock for new products or packaging. Something that is collected and sorted but then landfilled for lack of an end market still fails the test. The law also looks at a product’s physical shape and design, because certain forms can jam or contaminate the automated equipment at recovery facilities.1California Legislative Information. California Public Resources Code PRC 42355.51
The raw data for applying these tests comes from CalRecycle’s Material Characterization Study. The study surveys what is actually collected curbside and what is effectively sorted by processors. It does not issue pass-or-fail rulings on specific products; that call is left to the brand.3CalRecycle. Accurate Recycling Labels The study is updated every five years, with the first refresh due in 2027, and CalRecycle can publish supplemental data in between.1California Legislative Information.

What You Can and Can’t Put on the Package
The chasing arrows symbol is the headline target, but the restriction is broader. Any similar graphic, or any text telling consumers to recycle the item, is treated the same way. “Please recycle” and “100% recyclable” are presumptively deceptive if the material does not meet the two-threshold test. The presumption is a legal one, which means the burden sits on the manufacturer to prove the claim is accurate rather than on the state to prove it false.1California Legislative Information. California Public Resources Code PRC 42355.51 It does not matter that a material can technically be recycled at some specialized facility somewhere. If California’s mainstream system doesn’t collect and process it, you can’t label it recyclable.
Resin Identification Codes
The numbered codes stamped on plastic products (1 through 7) have their own rule. Under Public Resources Code Section 18015, the number cannot sit inside a chasing arrows symbol unless the specific resin meets the statewide recyclability criteria. Manufacturers who still need to display the code must use a solid equilateral triangle instead.4California Legislative Information. California Code PRC 18015 This creates a conflict for national brands, because at least 29 other states require the chasing arrows around the resin code. California-specific packaging may be the only way to satisfy both regimes.
Why FTC Green Guides Won’t Save You
Under California’s general environmental marketing statute, Business and Professions Code Section 17580.5, a company can usually defend a green claim by showing it followed the Federal Trade Commission’s Green Guides. SB 343 strips that defense for recyclability claims specifically.5California Legislative Information. California Business and Professions Code BPC 17580.5 The FTC’s “substantial majority” standard is not enough. A label that passes federal muster but fails California’s thresholds is still a violation.
Proving Your Claim Is Defensible
There is no state-run review or pre-approval process. Each brand evaluates its own packaging against CalRecycle’s published data and decides whether a recyclability claim will hold up.3CalRecycle. Accurate Recycling Labels CalRecycle publishes findings; it does not approve or reject individual labels.
Under Business and Professions Code Section 17508, the Attorney General, any district attorney, county counsel, or city attorney can demand that a company produce evidence supporting an advertising claim. A company that cannot produce documentation faces a presumption that its labeling is deceptive.6California Legislative Information. California Business and Professions Code BPC 17508 In practice, that means keeping records of the material composition of every package, how it maps to CalRecycle’s characterization data, and evidence that both the material type and its physical form meet the 60 percent collection and sorting thresholds. Coordinating with packaging suppliers is the only way to build this record before a claim is challenged.
Penalties for Non-Compliant Labels
SB 343 has no standalone penalty provision. Violations are prosecuted under California’s existing consumer protection framework, mainly the false advertising and unfair competition statutes in the Business and Professions Code. The Attorney General, district attorneys, county counsel, and city attorneys can all bring actions.
Section 17536 sets the civil penalty for each false advertising violation at up to $2,500.7California Legislative Information. California Business and Professions Code BPC 17536 Each non-compliant product unit can count as a separate violation, so exposure for a widely distributed consumer product adds up fast. Section 17500 also makes false advertising a misdemeanor punishable by up to six months in jail, a fine of up to $2,500, or both.8California Legislative Information. California Business and Professions Code BPC 17500 Courts can issue injunctions forcing immediate removal of non-compliant products from shelves, and an SB 343 violation can serve as the underlying unlawful act for a broader Unfair Competition Law claim under Section 17200, which opens the door to restitution and additional injunctive relief.
Can Consumers Sue?
SB 343 itself does not grant consumers a private right of action. A shopper cannot sue a brand directly for violating the labeling rules. But non-compliant labels can still fuel private litigation under other statutes. The Consumer Legal Remedies Act, starting at Civil Code Section 1750, prohibits misrepresenting the certification or approval status of goods. The Unfair Competition Law lets private plaintiffs challenge any business practice that violates a separate statute. An SB 343 violation can be the factual basis for a claim under either.
The Pending Federal Lawsuit
In March 2026, a coalition of trade associations, including the California League of Food Producers, the American Forest and Paper Association, and the Flexible Packaging Association, filed suit in the U.S. District Court for the Southern District of California. The case, California League of Food Producers v. Bonta, argues that SB 343’s labeling restrictions compel or restrict commercial speech in violation of the First and Fourteenth Amendments. The plaintiffs target both the chasing arrows rules in Section 42355.51 and the resin code requirements in Section 18015.
The outcome could reshape how the law is applied or strike parts of it. For now, the October 2026 deadline remains in force. Companies that pause compliance while waiting for a ruling carry the full exposure if the law is upheld.
