How2Recycle processes 29% more packaging labels to dodge SB 343 fines

The October 2026 Deadline Drives Industry Action

The clock is ticking toward October 4, 2026. California's Senate Bill 343 (SB 343) will fundamentally alter how packaging manufacturers communicate end-of-life instructions. Despite a recent July 2026 federal injunction temporarily pausing enforcement by the California Attorney General, the industry is not waiting. How2Recycle, the standardized labeling system operated by GreenBlue, has registered a 29% year-over-year increase in label requests as brands scramble to verify their claims.

Strict Thresholds for Paperboard and Corrugated Formats

SB 343 prohibits the use of the "chasing arrows" symbol or any recyclability claims unless the packaging meets strict criteria—specifically, being collected and accepted by recycling programs serving at least 60% of California's population. For the corrugated and paperboard sector, this is a critical stress test. While paper-based packaging generally boasts high recovery rates, complex formats like coated paperboard, aseptic cartons, and molded pulp must prove their compliance using CalRecycle's Material Characterization Study data.

The American Forest & Paper Association (AF&PA) has long championed the high recovery rates of fiber-based materials, but the new California law requires granular proof at the SKU level. Converters are now forced to evaluate every adhesive, barrier coating, and window film used in their folding cartons to ensure they do not disrupt the repulping process or drop the material below the 60% acceptance threshold.

Cartons Secure a Win Amid Regulatory Uncertainty

There is positive momentum for specific fiber-based formats. In June 2026, CalRecycle updated its findings to confirm that food and beverage cartons now meet the statewide sortation threshold, reaching 62% of California counties. This update, championed by the Carton Council, allows How2Recycle to continue issuing "Widely Recyclable" labels for aseptic and gable-top cartons. However, brands using mixed-material paper packaging are aggressively auditing their portfolios to avoid the escalating civil penalties—$500 for a first violation, up to $2,000 for subsequent ones—that can still be enforced by local jurisdictions and private plaintiffs.

Transition Planning and Supply Chain Adjustments

The 29% spike in How2Recycle requests reflects a defensive but necessary maneuver by packaging converters and consumer brands. Redesigning a corrugated mailer or a folding carton to eliminate non-compliant coatings takes months of lead time. Companies are stripping away ambiguous greenwashing and relying on verified, data-backed labeling to maintain their market access in the fifth-largest economy in the world. Transition plans are currently being executed across the supply chain to exhaust non-compliant inventory before the October deadline.

The rigorous threshold of SB 343 is exactly the kind of regulatory pressure the paper packaging industry needs to definitively separate genuine fiber recovery from superficial green marketing. Will the cost of compliance and continuous material auditing force smaller converters to abandon complex paperboard designs in favor of standard, uncoated corrugated formats?
