(a)

1. (1) Except as provided in paragraph (3), a person shall not sell or offer for sale a product in this state that is labeled with the term “compostable” or “home compostable” unless, at the time of sale or offering for sale, the product meets the applicable ASTM standard specification, as specified in paragraph (1) of subdivision (b) of Section 42356, or, if applicable, the product has OK compost HOME certification, as provided in paragraph (4).
2. (2) Compliance with only a section or a portion of a section of an applicable ASTM standard specification does not constitute compliance with paragraph (1).
3. (3) Notwithstanding paragraph (1), a person may sell or offer for sale a product in this state that is labeled with a qualified claim for a term specified in paragraph (1), if the product meets the relevant standard adopted by the department pursuant to Section 42356.2.

4. (4)

   1. (A) A product shall not be labeled with the term “home compostable” unless the manufacturer of that product holds OK compost HOME certification with regard to that product, except as provided in subparagraph (B) or (C).
   2. (B) Notwithstanding paragraph (1), if the ASTM adopts a standard specification for the term “home compostable” on or before January 1, 2016, and the department determines that the ASTM standard specification is at least equal to, or more stringent than, the OK compost HOME certification, a product labeled with the term “home compostable” shall meet that ASTM standard specification. The department may also take the actions specified in Section 42356.1 with regard to an ASTM standard for home compostability.
   3. (C) If the department adopts a standard pursuant to Section 42356.2, a product labeled with the term “home compostable” shall meet the standard adopted by the department and not the standard specified in subparagraph (A) or (B).

(b)

1. (1) Except as provided in subdivision (a) or (f), a person shall not sell or offer for sale a product in this state that is labeled with the term “biodegradable,” “degradable,” or “decomposable,” or any form of those terms, or in any way implies that the product will break down, fragment, biodegrade, or decompose in a landfill or other environment.
2. (2) For purposes of this subdivision, “implies” includes, but is not limited to, using green, beige, or brown tinting or color schemes on a plastic precheckout or carryout bag that is not eligible to be labeled with the terms “compostable” or “home compostable” pursuant to this section.

(f)

1. (1) The department may adopt the European Committee for Standardization’s standard specification EN 17033:2018 entitled “Plastics—Biodegradable mulch films for use in agriculture and horticulture—Requirements and test methods” or may adopt a standard that is equivalent to, or more stringent than, that standard, as it read on January 1, 2020.
2. (2) A person may sell or offer for sale commercial agricultural mulch film labeled with the term “soil biodegradable” only if the department has adopted the standard specification, or an equivalent or more stringent standard, pursuant to paragraph (1) and the commercial agricultural mulch film is certified to meet both that specification and the ASTM standard specification for compostability.
3. (3) For purposes of this subdivision, “commercial agricultural mulch film” means film plastic that is used only as a technical tool in commercial farming applications.

(g)

1. (1) A person shall not sell or offer for sale a product in this state that is labeled with the term “compostable” or “home compostable” unless the product satisfies all of the following:

   1. (A) If any standard specification is applicable to the product pursuant to this chapter and the department has approved a third-party certification entity to certify products according to that standard specification, the product shall have certification that it meets at least one such standard from an approved third-party certification entity for the standard. This requirement shall only apply on and after January 1, 2024, and it shall not apply unless there is, and has been for at least one year immediately prior to the product being sold or offered for sale, a third-party certification entity approved by the department to provide the applicable certification.

   2. (B) On and after January 1, 2026, is an allowable agricultural organic input under the requirements of the United States Department of Agriculture National Organic Program. By January 1, 2024, the department, through a public stakeholder process, shall determine whether, for purposes of this section, it would be feasible to separate the collection of products in order to recover organic waste that is suitable for use in organic agricultural applications from the collection of products not suitable for use in organic agricultural applications. If the department determines that such bifurcation is feasible and would enable efficient processing by solid waste processing facilities, the department shall adopt regulations on or before January 1, 2026, to establish a bifurcated approach, and products that are not collected for the purpose of recovering organic waste that is suitable for use in organic agricultural applications shall comply with the department’s regulations and are not subject to the requirements of this subparagraph. The director may grant a five-year extension for complying with this requirement if either of the following apply:

      1. (i) The product or substance has or will soon be, as determined by the director, included as allowed on the National List of Allowed and Prohibited Substances (Sections 205.600 to 205.607, inclusive, of Title 7 of the Code of Federal Regulations).
      2. (ii) The product or substance has or will soon be, as determined by the director, included as an allowable organic input for compost under federal law.
   3. (C) Does not have a total organic fluorine concentration of greater than 100 parts per million, unless the department adopts a different standard that it determines would more effectively limit the presence of perfluoroalkyl or polyfluoroalkyl substances.
   4. (D) Is labeled in a manner that distinguishes the product from a noncompostable product upon reasonable inspection by consumers and to help enable efficient processing by solid waste processing facilities.
   5. (E) Is designed to be associated with the recovery of desirable organic wastes, such as food scraps and yard trimmings, that are collected for composting, unless the product complies with the department’s regulations pursuant to subparagraph (B), to the extent the department elects to adopt such regulations.
2. (2) The department may adopt regulations for determining whether products comply with the requirements of subparagraph (D) of paragraph (1). The department, in adopting regulations pursuant to this subdivision, may consider whether the regulations are consistent with the product labeling requirements of other states, stakeholder input, and industry-standard guidelines. The regulations may include requirements that products are not designed, pigmented, or advertised in a manner that is misleading to consumers.
