California SB 343 Recycling-Claim Review: Evidence for Packaging, Listings and Manufacturing Dates

Who should use this guide: cross-border sellers, brand owners, packaging and design teams, and the people responsible for Amazon listings, packaging copy and supplier records when products or packaging are sold in California.

California SB 343 (Allen, Chapter 507, Statutes of 2021) addresses recyclability claims, chasing-arrows symbols and other statements that direct consumers to recycle a product or package. CalRecycle currently states that, following publication of the final material-characterization study on April 4, 2025, the labeling restrictions apply to products and packaging manufactured after October 4, 2026. The relevant trigger is the manufacturing date, not the date of sale. A seller should not turn that date into a claimed platform takedown deadline, or treat a resin code or supplier letter alone as proof that a finished package is recyclable.

1. Fix the legal object and the timing boundary first

SB 343 concerns statements on a product, package, label or advertisement that say a product is recyclable, use a chasing-arrows symbol, or otherwise direct a consumer to recycle it. “Packaging” should not be reduced to the retail carton: map the product-contact package, outer carton, grouped packaging and any other component that carries a recycling representation. The scope also needs a product-specific review of the sales route, California access, manufacturing date and material form. A China-based manufacturer or an Amazon US listing does not answer those questions by itself.

As of this review, CalRecycle’s published timeline is: the 2023/2024 final material-characterization study was published on April 4, 2025, and the 18-month transition period ends on October 4, 2026. That does not mean a package manufactured before the date is permanently outside every environmental-marketing rule. For packages manufactured after the date, SB 343 review should be part of the packaging and listing change process.

2. “Recyclable” requires collection, sorting, reclamation and design evidence

California Public Resources Code section 42355.51 does not let a seller prove recyclability only by naming a resin. Based on information published by the department, a material type and form generally needs to fit the following statewide pathway:

1. Collection coverage: the material type and form is collected for recycling by programs serving jurisdictions that collectively encompass at least 60% of California’s population.
2. Sorting and destination: the material type and form is sorted into defined recycling streams by qualifying large-volume transfer or processing facilities that collectively serve at least 60% of statewide recycling programs, with the streams sent to a qualifying reclamation facility.
3. Product design: plastic packaging must be assessed with the APR Design® Guide in mind; plastic and non-plastic products and packaging must not include components, inks, adhesives or labels that prevent recyclability.
4. Chemical boundary: the statute also addresses certain intentionally added chemicals identified in implementing regulations and PFAS that are intentionally added or present at or above the statutory total-organic-fluorine level. The unsupported test panel, fixed ppm values and universal per-lot ISO 17025 requirement in the original article should not be presented as a general SB 343 checklist.

The statute also contains alternative routes, including a product or package with a demonstrated recycling rate of at least 75%, and certain non-curbside programs that meet recovery, commercial-value and transport conditions before 2030. These are specific statutory routes; one recycled-content percentage cannot replace the full evaluation.

3. Use CalRecycle’s study without overstating what it proves

CalRecycle’s material-characterization study records material types and forms collected, sorted, sold or transferred by California facilities. Its June 2026 update also shows that data for some carton categories changed, while expressly noting that the update is not a determination that a particular product is recyclable and is not a recycling-rate determination. A SKU-level evidence file should retain at least:

• the packaging BOM, material type, form, dimensions and layer structure;
• the manufacturing date, version, printing, inks, adhesives, coatings and labels;
• the relevant CalRecycle material-type-and-form entry, updates and retrieval date;
• supplier technical records, formulation or chemical declarations, and any applicable test or design documents;
• before-and-after versions and the review decision for each packaging, material or listing change.

Do not write that a package was “approved by CalRecycle” because its material category appears in a study. Do not transfer the result for a clear PET bottle to a coloured, laminated, composite or differently sized tray. The study is one part of the assessment; the finished design and chemical boundaries still require a separate review.

4. Keep the listing and package claim tied to the same SKU version

The claim in an Amazon listing, A+ content, Brand Store, package front, manual and image should refer to the same SKU and package version. The following is an internal review framework, not a platform policy or a legal conclusion:

Review item	Question to answer	Evidence to retain
Recyclable wording or chasing arrows	Which package component and manufacturing version does it describe? Have collection, sorting and reclamation conditions been reviewed?	Material-form assessment, CalRecycle references, design/chemical records, reviewer and date.
Recycled content	Does the statement describe manufacturing input, or end-of-life recyclability? Which component and lot does the percentage cover?	Supplier and lot records, with recycled content and recyclability kept as separate claims.
FSC, BPI or another mark	Does the certification scope cover this holder, material and version? Is the mark being expanded into a claim that the whole package is recyclable?	Certificate scope, holder, validity, covered component and final package/listing screenshots.

Where the evidence is incomplete, a cautious internal approach is to pause an unsupported “recyclable” or “100% recyclable” statement, use an objective material description supported by the BOM, and decide whether to restore the environmental claim after review. Do not replace the same unsupported promise with broad words such as “eco-friendly” or “sustainable packaging.” Do not present platform display, listing edits or delisting as a statutory SB 343 outcome.

5. A single-SKU checklist for a cross-border team

1. Confirm the sales route, California purchase path and manufacturing date for each package version. Flag versions manufactured after October 4, 2026.
2. Map each SKU’s product package, outer carton, grouped packaging and any other component carrying an environmental representation. Record material, form, dimensions, coatings, inks, adhesives and labels.
3. Use the latest CalRecycle study, FAQ and updates to review the material type and form. Do not rely on a resin code alone or apply the 60% figure by counting counties.
4. Check whether the design of plastic and non-plastic packaging, its components and its chemical profile create a statutory issue. If testing is needed, define the question and method before commissioning technical work.
5. Compare the package, listing, A+ content, images and manuals. Keep “recyclable,” “recycling symbol,” “recycled content” and “compostable” as distinct claims.
6. Save source links, retrieval dates, versions, evidence, approval notes and change screenshots. Reassess when the material, supplier, ink, adhesive or package structure changes.
