U.S. District Court, Southern District of California  |  3:26-cv-01675-WQH-JAC (Judge William Q. Hayes)  |  Filed March 17, 2026 verified July 21, 2026

In plain English: what this means for you

Do not tear up your labeling plan. California cannot enforce SB 343 right now, but the law is still on the books, the ruling is preliminary rather than final, and it can be appealed or reversed. On-pack changes have long lead times, so the safe read is to keep designing to the SB 343 rules. The bigger point is upstream: California uses SB 343 criteria to decide what counts as recyclable for SB 54 fees, so this uncertainty reaches your 2027 fee position, not just your artwork.

This is a plain reading of where the case stands, not legal advice. If your exposure is material, confirm it with counsel.

What is being challenged

SB 343, the Truth in Recycling labeling law, on First Amendment and Fourteenth Amendment vagueness grounds. Brought by a coalition that grew from 18 to 21 food, packaging and retail trade associations.

Where it stands

Preliminary injunction granted July 14, 2026, barring the Attorney General from enforcing SB 343 until further order. Four provisions were found unconstitutionally vague and severed, so the 60 percent collection-and-sorting threshold survives on paper while enforcement is paused. No notice of appeal has been reported, though a preliminary injunction is immediately appealable.

Who is affected

Enforcement is paused less than three months before the October 4, 2026 compliance deadline. Because SB 54 relies on SB 343 recyclability criteria to decide what counts as recyclable in California, the ruling reaches beyond labeling into the fee program.
