Court Halts Enforcement of California's Truth in Labeling Law

3 min readSources: National Law Review

A federal court blocked enforcement of California's Truth in Labeling law for certain trade groups.

Why it matters: This injunction pauses enforcement of SB 343, impacting compliance strategies for product labeling laws. In-house counsel and compliance officers must monitor developments affecting consumer protection and environmental regulations in California.

  • On July 14, 2026, a federal judge granted a preliminary injunction halting SB 343 enforcement against 18 trade associations.
  • SB 343 restricts recyclability labels like the 'chasing arrows' to products meeting defined recycling standards, effective October 4, 2026.
  • Plaintiffs argue SB 343 is vague and violates First Amendment commercial speech protections.
  • The injunction also blocks enforcement by California Attorney General Rob Bonta pending ongoing litigation.

On July 14, 2026, the U.S. District Court for the Southern District of California issued a preliminary injunction halting enforcement of California's Senate Bill 343 (SB 343), known as the 'Truth in Labeling' law, against a coalition of 18 trade associations including the Flexible Packaging Association and the California League of Food Producers. This injunction was granted as part of legal challenges filed on March 17, 2026, which contest the law's constitutionality.

SB 343, enacted on October 5, 2021, limits the use of recyclability symbols such as the 'chasing arrows' on product packaging unless the products meet specified recycling criteria. The law was scheduled for enforcement beginning October 4, 2026, following an 18-month grace period triggered by CalRecycle's material characterization study published on April 4, 2025.

Judge William Q. Hayes found that the plaintiffs demonstrated a likelihood of success on their claims that SB 343 is unconstitutionally vague and infringes upon First Amendment rights by restricting commercial speech. As a result, the court concluded that enforcement should be paused while the case proceeds. The preliminary injunction prevents California Attorney General Rob Bonta from enforcing the law against the plaintiffs.

Legal experts note the injunction raises significant questions for California's broader recycling policy landscape. Davis Wright Tremaine highlighted that the order casts doubts on the viability of the state's Extended Producer Responsibility program (SB 54), which relies on SB 343’s standards to meet recyclability targets.

This development creates immediate uncertainty for companies preparing to comply with new packaging labeling requirements in California. Businesses and legal teams should monitor the case as it progresses, given its potential to reshape regulatory expectations around recyclability claims.

By the numbers:

  • October 5, 2021 — Date SB 343 was enacted
  • October 4, 2026 — Planned start of SB 343 enforcement
  • 18 — Number of trade associations challenging SB 343
  • July 14, 2026 — Date preliminary injunction was granted

What's next: Ongoing litigation will determine the final constitutionality of SB 343; enforcement remains paused pending resolution.
