Federal court preliminarily enjoins California’s SB 343 recyclability labeling law

The U.S. District Court for the Southern District of California recently issued a preliminary injunction preventing California from enforcing Senate Bill 343 (SB 343), commonly known as the “Truth in Recycling” law. SB 343 had been scheduled to take effect on October 4, 2026.

The law restricts the use of the “chasing arrows” symbol and certain other recyclability claims on packaging unless the packaging satisfied California-specific recycling criteria. Under the court’s order, U.S. District Judge William Q. Hayes enjoined California Attorney General Rob Bonta from enforcing SB 343 pending further order of the court.

Court finds plaintiffs likely to prevail on commercial-speech and due-process claims A coalition of 21 industry trade associations, including the California League of Food Producers, the Flexible Packaging Association, and the American Forest & Paper Association, challenged SB 343 in federal court. Plaintiffs argued that the statute unlawfully restricts commercial speech and does not provide businesses with adequate notice of the conduct it prohibits.

The court found that plaintiffs were likely to succeed on those constitutional claims. Applying intermediate scrutiny to the commercial-speech restrictions, the court concluded that SB 343’s limits were more extensive than necessary to advance California’s stated interests in reducing consumer confusion and improving recycling outcomes. The court also concluded that California had not sufficiently shown that restricting truthful, qualified recyclability information would materially advance those interests.

The court separately found that several of SB 343’s standards may be unconstitutionally vague under the Fourteenth Amendment’s Due Process Clause. The order identified concerns with requirements tied to whether a material “routinely becomes feedstock,” the evolving APR Design Guide, and compliance with the Basel Convention.

For manufacturers and brand owners, these standards created substantial uncertainty because they may change over time or depend on terms that do not clearly identify what packaging or claims are permitted. The court concluded that the challenged provisions may fail to give businesses of ordinary intelligence fair notice of their compliance obligations.

The court further noted that the law’s restrictions and potential enforcement consequences could discourage companies from providing otherwise truthful recyclability information. Manufacturers facing uncertain standards and potential penalties may remove recycling instructions and symbols from packaging altogether, rather than risk enforcement. According to the court’s reasoning, that outcome could deprive consumers of useful environmental information and undermine recycling efforts.

What the injunction means for manufacturers, brands, and retailers

Companies that have accelerated packaging audits, artwork revisions, SKU rationalization, or California-specific inventory planning in anticipation of the October 2026 effective date may have temporary relief. The preliminary injunction pauses the immediate need to remove recycling symbols, resin identification codes, or other recyclability claims solely to comply with SB 343.

Businesses should not, however, automatically abandon work already underway. Packaging changes may remain appropriate where they support broader environmental, marketing, product-stewardship, or regulatory objectives. It is also possible the court will reverse the injunction and uphold the law.

The ruling is preliminary, not final

A preliminary injunction preserves the status quo while litigation continues; it does not resolve the merits of the constitutional challenge. California may seek appellate review in the U.S. Court of Appeals for the Ninth Circuit and may pursue other procedural options. Companies should continue to monitor the case closely because the injunction could be modified, stayed, narrowed, or reversed.

Recommended next steps

Companies should review active packaging redesigns and assess whether each initiative should continue, pause, or be revised. That review should account for the injunction, existing inventory commitments, design lead times, retailer requirements, and the company’s broader environmental commitments.

Businesses should also evaluate the relationship between SB 343 and other state packaging, labeling, and extended producer responsibility requirements. Oregon, Colorado, Minnesota, and other states continue to advance packaging and producer-responsibility regimes. California’s broader plastic packaging EPR program under SB 54 may also require continued attention, particularly to the extent its implementation relies on concepts or definitions related to SB 343.

Finally, companies should maintain substantiation for all environmental marketing claims. The injunction does not eliminate exposure under other consumer-protection laws, state labeling requirements, or class-action theories. Businesses should continue to evaluate on-pack environmental claims against applicable Federal Trade Commission guidance and relevant state law.
