California’s VOC regulations set product-by-product caps on how much volatile organic compound content paints, consumer products, adhesives, and sealants can contain when sold or used in the state. The California Air Resources Board (CARB) writes the statewide rules, local Air Quality Management Districts add their own on top, and civil penalties for a single violation start at $5,000 to $10,000 per day. Liability reaches manufacturers, distributors, and retailers, including out-of-state sellers shipping into California.
Who Has to Comply and Who Enforces
CARB’s Consumer Products Regulation applies to any person who sells, supplies, offers for sale, or manufactures a regulated product for use in California. That language is deliberately broad. Distributors and retailers carry the same exposure as manufacturers, and CARB has pursued distributors directly. A settlement with National Oak Distributors, Inc. involved a degreaser sold above the VOC limit for its category.1California Air Resources Board. National Oak Distributors Inc SA Settlement Agreement
Out-of-state online retailers are not outside the reach of the rules. If the product is for use in California, the California limit applies regardless of where the seller sits. Federal regulations expressly preserve each state’s authority to adopt and enforce its own emission standards.2eCFR. 40 CFR Part 59 Subpart C — National Volatile Organic Compound Emission Standards for Consumer Products
CARB runs two main statewide programs: the Consumer Products Regulations for household and institutional products, and the Architectural Coatings Suggested Control Measure for paints, stains, and varnishes.3California Air Resources Board. The California Consumer Products Regulations Local AQMDs implement those statewide rules within their regions and often adopt stricter ones. The South Coast AQMD, covering the greater Los Angeles area, is the most active example. Where a local district’s limit is tighter than CARB’s, the tighter number controls.
One vocabulary point worth carrying through the rest of this article: California’s regulatory definition of a VOC turns on a compound’s ability to contribute to ozone formation. Chemicals with negligible photochemical reactivity are classified as exempt compounds and don’t count toward a product’s VOC content.4eCFR. 40 CFR Part 59 — National Volatile Organic Compound Emission Standards for Consumer and Commercial Products A product can contain organic solvents and still comply if those solvents are on the exempt list.
Architectural Coatings
Paint and other architectural coatings are regulated separately from general consumer products. Limits are expressed in grams of VOC per liter (g/L). CARB’s Suggested Control Measure sets baseline statewide limits, and local districts either adopt them or tighten them.
The two broadest categories carry these statewide limits:
- Flat coatings: 50 g/L
- Nonflat coatings (satin, semi-gloss, gloss): 100 g/L
Those numbers come from CARB’s 2019 Suggested Control Measure.5California Air Resources Board. Appendix B 2019 Suggested Control Measure for Architectural Coatings Specialty categories like industrial maintenance and rust-preventive coatings have their own limits, and several districts are stricter than the statewide floor.6California Air Resources Board. VOC Limits Summary Check the AQMD rule for the region where the product will actually be applied. A label VOC content statement is mandatory on architectural coatings.
Consumer Products
Hairsprays, air fresheners, cleaning supplies, insecticides, and similar items are regulated under CARB’s Table of Standards at Section 94509 of Title 17 of the California Code of Regulations. Here the limits are stated as a maximum percentage of VOC by weight, and California’s caps run well below federal ones. Federal rules allow up to 80% VOC content for hairsprays; California is far stricter.2eCFR. 40 CFR Part 59 Subpart C — National Volatile Organic Compound Emission Standards for Consumer Products
A few representative numbers:
- Hair finishing spray: 50% VOC by weight, reduced from 55% effective January 1, 20237Legal Information Institute. Cal. Code Regs. Tit. 17, 94509 – Standards for Consumer Products
- Aerosol crawling bug insecticide: 15%
- Single-phase aerosol air freshener: 30%
- Double-phase aerosol air freshener: 25%
The Table of Standards covers well over 100 product categories, each with its own limit and phase-in schedule. CARB tightens limits periodically and gives advance notice so manufacturers can reformulate. Recent amendments also prohibit certain high-GWP chemicals and toxic compounds such as methylene chloride and trichloroethylene in specified product categories, with sell-through deadlines running through 2026.
Adhesives and Sealants
There isn’t a single statewide CARB rule that covers every adhesive. When an adhesive is a consumer product under CARB’s regulations, the statewide limit applies. For adhesives used in construction, industrial, and commercial applications, local AQMD rules typically govern.
South Coast AQMD’s Rule 1168 is the most widely referenced. It sets application-specific limits including:
- Indoor carpet adhesive: 50 g/L
- Multipurpose construction adhesive: 70 g/L
- Drywall and panel adhesive: 50 g/L
These are grams of VOC per liter of product, excluding water and exempt compounds.8South Coast AQMD. Rule 1168 Adhesive and Sealant Applications Other districts have parallel rules with numbers that may differ. Check the district rule for the location where the adhesive will be used.
Testing, Records, and Date Codes
Compliance has to be documented, not assumed. The two primary approved test methods are EPA Method 24 for coatings and CARB Method 310 for consumer products. A manufacturer can use formulation data to calculate VOC content, but lab testing controls if there’s a dispute.4eCFR. 40 CFR Part 59 — National Volatile Organic Compound Emission Standards for Consumer and Commercial Products
Manufacturers relying on formulation data must keep daily production records showing the amounts and chemical composition of individual product constituents, retained for at least three years.9Legal Information Institute. Cal. Code Regs. Tit. 17, 94515 – Test Methods That’s ingredient lists, formulation percentages, production volumes, and test results.
Every regulated consumer product container must display the date of manufacture (day, month, and year) or a code representing that date. If you use a code, it must be filed with CARB’s Executive Officer before the product enters the market. A code that only reflects a sequential batch number, with no link to a specific date, does not qualify.10California Air Resources Board. Product Dating Requirements This matters beyond labeling: date codes are how CARB decides whether older inventory still qualifies for a sell-through grace period.
Sell-Through When Limits Change
When CARB lowers a VOC limit, products already manufactured under the old limit generally get a three-year sell-through window. Distributors and retailers can keep selling that inventory for up to three years after the new limit takes effect, provided the container shows a valid date of manufacture or code.3California Air Resources Board. The California Consumer Products Regulations For pesticide products registered under the federal FIFRA statute, the three-year window starts one year after the effective date, giving those products four years total.
There is a shorter exception. Solid air fresheners and toilet care products containing para-dichlorobenzene get only a one-year sell-through. Once the window closes, previously compliant stock becomes a violation, so anyone holding inventory needs to track manufacture dates against CARB’s schedule of effective dates.
Exemptions and Variances
A product that exceeds its category limit can still be sold in California if it qualifies for an Innovative Product Exemption (IPE). The manufacturer must show by clear and convincing evidence that the product’s formulation, delivery system, or other design features result in lower total VOC emissions than a comparable compliant product in the same category and product form with similar effectiveness.11Legal Information Institute. Cal. Code Regs. Tit. 17, 94511 – Innovative Products The idea is that a higher-concentration product may still emit less total VOC if people use much less of it per application.
A separate IPE pathway exists for aerosol hair finishing sprays, dry shampoos, and personal fragrance products that cut greenhouse gas emissions by replacing HFC-152a propellant. Products manufactured before January 1, 2029 must achieve at least a 50% reduction in GHG emissions; products manufactured on or after that date must hit 90% or use only ingredients with a GWP below 10.11Legal Information Institute. Cal. Code Regs. Tit. 17, 94511 – Innovative Products
A temporary variance is a different tool. At the federal level, a manufacturer facing extraordinary circumstances beyond its reasonable control can apply, laying out the grounds, proposing a compliance date (no later than five years out for most categories), and submitting a compliance plan. The variance is granted only if compliance is not technologically or economically feasible at the time.4eCFR. 40 CFR Part 59 — National Volatile Organic Compound Emission Standards for Consumer and Commercial Products CARB runs a parallel state process. Variances are not routine, and they aren’t a compliance strategy.
Mandatory Product Surveys
Meeting the numeric limit isn’t the end of a manufacturer’s obligations. CARB periodically requires companies to submit detailed data about the products they sell in California through mandatory surveys. It has run these since the mid-1990s; the most recent covered calendar year 2023.12California Air Resources Board. FAQ – 2023 Consumer and Commercial Products Survey Any company that sold or supplied a regulated consumer product for use in California during the survey year must respond.
The data requested is formulation-level: chemical composition of each product, weight percentages of organic compounds, exempt compounds, and water. Individual fragrance ingredients need not be broken out, but the total fragrance content by weight and the fragrance supplier’s contact information must be reported. A representative product label goes in with each product.
Penalties
CARB and local AQMDs find violations through inspections, data analysis, public tips, referrals from other agencies, and the mandatory reporting described above. A substantiated violation is formalized in a Notice of Violation.13California Air Resources Board. Enforcement Policy – Updated October 2017 Penalties scale with intent:
- Strict liability, no intent or negligence required: $5,000 to $10,000 per violation per day under Health and Safety Code Sections 42400 and 42402.14California Legislative Information. California Health and Safety Code HSC 42402
- Negligent violations: up to $25,000 per day for negligently emitting an air contaminant.
- Knowing violations with failure to take corrective action: up to $40,000 per day.
- Willful and intentional emissions: up to $75,000 per day.
- Violations causing great bodily injury or death: between $250,000 and $1 million per day.
CARB and the local district can both pursue enforcement for the same violation, and cases often settle rather than litigate.13California Air Resources Board. Enforcement Policy – Updated October 2017 The final number turns on the severity of the violation, environmental harm, compliance history, and any economic benefit gained by not complying. Knowingly falsifying documents submitted to CARB is its own separate penalty of up to $35,000 per day.
