Packaging and labeling violations are among the most common reasons cannabis products are pulled from shelves. A missing THC warning, an incorrect net weight, or a font size that is 1 point too small can all trigger a recall or fine. The problem is that every state has different requirements, and those requirements change regularly. This guide is a living reference for the core requirements in major markets.
Universal requirements (most states)
- Product identity and category (flower, edible, concentrate, etc.).
- Net weight or volume in metric and imperial units.
- THC and CBD content per serving and per package.
- Universal THC symbol or state-specific warning symbol.
- Government warning statement about health risks.
- License number of the manufacturer or distributor.
- Batch or lot number for traceability.
- Date of manufacture and expiration or best-by date.
California: the strictest standard
California's DCC has the most detailed labeling rules in the country. Warning statements must be in specific fonts and sizes. THC content must be listed as milligrams per serving and per package. Edibles must include a full ingredient list and allergen warnings. The universal symbol must be at least 0.5 inches in diameter on the primary panel.
Child-resistant packaging
Every state requires child-resistant packaging for cannabis products, but the test standards differ. Some states accept ASTM D3475 certification. Others require CPSC testing. Some require resealable child-resistant closures for multi-dose products. If you are sourcing packaging from a vendor, verify that their certification matches your state's specific requirement. A package that is child-resistant in Colorado may not meet Washington's standard.
Labeling your own products versus white-label
If you manufacture your own products, you are responsible for label compliance. If you sell white-label or third-party products, you are still responsible for verifying that the label meets your state's requirements. The regulator does not care who printed the label. They care that the product on your shelf is labeled correctly.
Keeping up with changes
Labeling rules change. California updated its warning symbol in 2024. New York added social-equity tracking requirements in 2025. The only way to stay current is to subscribe to your state regulator's email list, join industry associations that monitor rule changes, and review your labels quarterly. When a rule changes, you typically have 90 to 180 days to comply. Use that window to redesign, reprint, and replace old inventory.
