California compostable law guide for shopping and trash bags
Table of Contents
This page gives a simple, usable view of California compostable rules so buyers, importers, and brands can quickly decide what to buy, request samples, or ask for a quote. It is not hype. It is what you need to meet the rules, print correctly, and work with a supplier who can deliver. This page is part of our USA compostable packaging laws overview.
What California actually requires, in plain language
California sets real limits on how products can be labeled as compostable. The rules matter for plastic or plastic‑coated bags and for packaging that claims home composting.
- California requires compostable plastic products to meet ASTM D6400 and plastic‑coated products to meet ASTM D6868. Home compostable claims require OK compost HOME certification.
- Rules also add limits on fluorine, require clear labeling, and design for organic waste recovery.
- By June 30, 2027, products must meet USDA National Organic Program allowable input rules. This is a timeline to watch when planning future orders.
These are not optional suggestions. They are the foundation for any California‑market compostable claim.
2025 pre‑checkout bag rules you must know
From January 1, 2025, California allows only two types of pre‑checkout bags in many stores: recycled paper or compostable bags. This is for loose produce, bulk food, or to protect items before checkout.
For compostable pre‑checkout bags, the rules include:
- No recycling arrow symbol or resin code shown.
- No words like biodegradable or degradable that imply breakdown elsewhere.
- At least 15‑inch mouth width.
- Color and labeling rules. Green color plus the word compostable in the right size and place.
- Must meet ASTM D6400, verified by an independent third party, and show certification logo.
- Limits on PFAS.
- Home compostable claim needs OK compost HOME certification.
- From January 1, 2026, must meet USDA allowable agricultural organic input rules as noted.
In short: if you plan to supply shopping bags or trash bags that may be used as pre‑checkout bags, every point above is a check that your product, label, and documentation must pass.
How buyers can use this page today
Use the following steps to decide and to contact a supplier with confidence.
Step 1. Match bag type to the exact rule set
- Shopping bags or trash bags for stores with pre‑checkout use must follow the 2025 requirements above.
- Other uses still must meet the core labeling and standard requirements from the state truth‑in‑labeling rules.
This keeps you safe from two common mistakes:
- thinking any compostable bag is OK, and
- confusing what is legal to sell with what local facilities accept. California rules focus on legal labeling and allowable bag types for stores; local composting acceptance can differ by city or program, which is a separate reality to check locally.
Step 3. Request samples or a quote only after documentation is confirmed
When a supplier shows both the right certification and the correct label design, requesting a sample is a low‑risk next move. A sample lets you check print, material feel, and bag dimensions before bulk order. Then you can ask for a quote with clear specs, MOQ, lead time, and certificate copies.
What a reliable supplier should deliver to you
For shopping and trash bags meant for California:
Clear certification materials
Proof of ASTM D6400 or D6868 compliance, plus third‑party logo if required.
Any home compostable proof if used.
Current statements on PFAS and related limits.
Label and print guidance
Exact green color use, placement of compostable wording, font size, and side rules.
Examples of correct and incorrect labels, so your printer or the supplier’s line does not slip.
Timeline and change notice
Note the 2026‑2027 timeline for USDA allowance.
Explain how changes could affect future batches or label wording.
Sample plan and quote basics
Offer a sample shipment for inspection.
Provide a written quote with specs, weight, thickness, color, sizes, MOQ, lead time, and shipping notes.
When you get all four, you can move from research to a real purchase with less risk.
Practical tips for making a safe choice now
- Do not rely on general claims alone. Ask for the exact standard and proof.
- Keep label design simple and compliant. If your design uses other symbols or words, it may fail even if the film or resin is compliant.
- Plan orders in the next 18–36 months with an eye on the USDA rule timeline. This helps avoid last‑minute changes or wasted stock.
- Check both seller rules and local facility rules. You may sell and label correctly but still face local acceptance limits; that is a separate check, not a reason to ignore state rules.
These steps are not hard. They are precise. They let you buy and sell in California without guesswork.

We will share the certification documents, label approvals, and any updates tied to California’s rules and timelines. That way your purchase is practical, compliant, and ready for real store use.
FAQ quick notes
It is the main California standard for compostable plastics. You need third‑party verification and logo for bags that use the compostable label in California.
No. California limits symbols like chasing arrows, and sets strict color and wording rules. Use only the allowed labels and colors in the official guidance.
The law timeline notes a point to watch on January 1, 2026, with further statewide rules linked to USDA allowance by June 30, 2027. This is a schedule for future compliance checks.
These notes help you judge a supplier quickly. If a supplier cannot answer them clearly or show proof, move to another partner.
