SB 343 reaches its deadline, but enforcement is on hold

October 4, 2026 was supposed to be the day California stopped tolerating loose recyclability claims. It arrived on schedule. What didn’t arrive was a functioning enforcement regime.

A federal judge blocked the state Attorney General from enforcing SB 343 back in July, and that order is still in place. The statute’s text, however, did not change, and the compliance date CalRecycle built into its guidance did not move. Packaging teams selling into California are now operating in a gap between a law that is formally live and an enforcement mechanism that is formally paused.

What the law requires

California enacted SB 343 in 2021, prohibiting use of the chasing arrows or any other indicator of recyclability on products and packaging unless certain criteria are met. The core mechanism is often called the “60/60 rule”: a material can only be called recyclable if it is actually collected in programs serving 60% of California’s population and sorted by facilities serving at least 60% of statewide recycling programs, among other parameters.

The law outlaws manufacturers and others from selling products or packaging labeled as recyclable unless the items are regularly collected and processed for recycling in the state. Notably, SB 343 neither authorizes nor directs CalRecycle to determine or report on the recyclability of particular products and packaging or the appropriate use of the chasing arrows or other indicators of recyclability. In practice this means there is no state approval stamp a brand can obtain. The burden of proof sits with the producer, and the producer has to build its own evidentiary file.

Two details matter for production planning. SB 343’s restrictions apply based on the date of manufacture, not the date of sale, so products and packaging manufactured before October 4, 2026 are not subject to the labeling restrictions regardless of when they are subsequently sold or distributed. And CalRecycle itself does not have enforcement authority under SB 343 and does not make product-by-product determinations regarding the lawfulness of specific labeling practices, which leaves the actual recyclability call to each company’s own legal and technical review.

Why a judge paused enforcement

In March 2026, a coalition of industry associations challenged SB 343, alleging violations of the First and Fourteenth amendments to the US Constitution and seeking both declaratory and injunctive relief. The plaintiffs, including the Flexible Packaging Association and the California League of Food Producers, argued the statute’s standards were too vague for a company to apply with confidence and that the restriction on truthful recyclability claims was an unconstitutional limit on commercial speech.

On July 14, 2026, the US District Court for the Southern District of California granted a preliminary injunction barring California Attorney General Rob Bonta, and those in privity or acting in concert with him, from enforcing SB 343. The judge ruled the law is unconstitutionally vague and unsupported by evidence that it would actually improve recycling rates. Commercial speech cases like this one are judged under the Central Hudson factors, the four-part legal standard set by the Supreme Court in Central Hudson Gas & Electric Corporation v. Public Service Commission of New York, and the court found the state had not cleared that bar.

The ruling is a preliminary injunction, not a final judgment. Litigation continues before the court, and an appeal to the Ninth Circuit is likely. Nothing about the underlying statute has been struck down. A later ruling on the merits, or a stay pending appeal, could reinstate enforcement with little notice.

The gap between “enjoined” and “safe”

This is the part packaging teams tend to misread. The injunction stops one specific actor, the Attorney General, from bringing enforcement actions. It does not say the law is unenforceable by anyone else, and it does not resolve the underlying question of whether specific claims on specific packages comply.

A legal analysis from Morgan Lewis flagged a structural reason this matters. The Supreme Court’s decision in Trump v. Casa arguably limits the applicability of the injunction to the parties to the litigation, so any district attorney or private actor could seek to enforce the statute’s recyclability criteria, and any consumer could seek to recover damages for alleged violations of the statute, because they are not in privity with or acting in concert with the Attorney General. A Q&A circulated by the Association of Plastic Recyclers made a similar point more plainly: the injunction does not extend to the implementation of the law, nor does it address the ability of private party plaintiffs to indirectly enforce SB 343 via private litigation.

SB 343 does not create its own private right of action, but that is not the same as immunity. Violations under SB 343 can be enforced by private citizens in consumer claims, including California’s False Advertising Law, the Consumers Legal Remedies Act, and the Unfair Competition Law, in addition to enforcement by the Attorney General. A company’s exposure also runs through disclosure obligations: a private citizen or member of the public is entitled to request, and a company must furnish, substantiation on SB 343 compliance if a consumer product has a recyclability claim or chasing arrow symbol. Law firm Benesch summarized the likely result bluntly: the enforcement model is similar to California’s Proposition 65, a framework well known for generating high volumes of private enforcement litigation. Civil penalties under the relevant unfair competition provisions permit civil penalties of up to $2,500 per violation and may be invoked by public prosecutors or private parties.

Read together, these sources point to the same practical conclusion. The injunction removes the immediate threat of an Attorney General enforcement sweep. It does not remove the incentive for plaintiffs’ firms or advocacy groups to bring consumer-protection claims over specific labels, and it does not change what a company would need to show if it were sued.

Why this reaches into the EPR program too

SB 343’s material-by-material recyclability determinations don’t stay inside a labeling silo. Material-specific recyclability determinations also have implications in the extended producer responsibility program established by 2022’s SB 54. A material that fails the 60/60 test for labeling purposes is also a material that looks worse under SB 54’s eco-modulated fee structure, since both regimes lean on the same CalRecycle data about what actually gets collected and sorted in the state.

Beverage cartons show how quickly that status can move. When a major hauler suspended carton sortation at one facility, CalRecycle issued an updated SB 343 data point showing the pause had left only 53% of Californians with access to beverage carton recycling, below the 60% access threshold needed for the material to be considered recyclable under SB 343. The underlying recycling performance was already weak: aseptic and gable-top cartons had a less than 1% recycling rate in the state in 2024, according to a CalRecycle report. A brand using carton packaging today has no guarantee that a “recyclable” claim it can substantiate this quarter will still be defensible next quarter, independent of anything the courts decide about SB 343’s constitutionality.

Open questions

The biggest unknown is timing. Nobody covering the case has put a date on a Ninth Circuit ruling, and a stay pending appeal could reinstate Attorney General enforcement before the underlying constitutional questions are ever resolved on the merits.

A second unknown sits inside CalRecycle’s own process. CalRecycle is required to update its recyclability findings in 2027 and every five years after that, so compliant materials today can fall out of compliance later. That update cycle runs independently of the litigation calendar. A label that is defensible under this year’s data could stop being defensible under next year’s, whatever happens in court.

A third unknown is how isolated SB 343 actually is. Industry group ILMA has noted that the SB 343 injunction sits alongside an Oregon EPR trial and a pending SB 54 lawsuit in California, among other state-level challenges, suggesting courts are taking a harder look at the legal foundations of several state packaging regimes at once, not just this one.

What to do now

Keep auditing claims. Review chasing-arrows symbols, resin identification codes, and recyclability language on every SKU sold into California, including co-branded and private-label lines. The injunction pauses state enforcement; it does not retroactively validate a weak claim.
Build and keep substantiation files. Because a member of the public can request proof of a recyclability claim, documentation that shows how a determination was made is now a baseline control, not a nice-to-have.
Track the manufacture-date trigger separately from your sale-date planning. Inventory manufactured before October 4, 2026 is not subject to the restrictions regardless of when it sells through; new production runs are a different question.
Treat the pause as temporary in your planning calendar. Don’t reverse artwork changes made in anticipation of the deadline without legal sign-off; a stay or reversal on appeal could arrive with little warning.
Watch material-specific status, not just the law. For materials like cartons, flexible films, or multi-layer structures, the underlying collection and sorting data can move faster than the litigation. Reconfirm recyclability status against CalRecycle’s latest published figures before each print run.
