California's Sell-By Date Ban
What Supplement and Vitamin Brands Need to Know and Why Icelandirect Clients Are Already Covered
If you sell dietary supplements or vitamins in California, a significant labeling change takes effect July 1, 2026. California’s Assembly Bill 660 (AB 660), signed into law in 2024, makes California the first U.S. state to ban consumer-facing “sell-by” dates on packaged products and non-compliance means your product may not be legally sold in the nation’s largest state economy.
At Icelandirect, we believe our clients should be spending their energy on growing sales, not decoding the latest regulatory curveball. That’s why we’ve already ensured our labeling processes are fully AB 660 compliant ahead of the July 1 deadline.
What AB 660 Actually Requires
While AB 660 was drafted primarily with packaged foods in mind, dietary supplements and vitamins fall squarely within its scope. The law is straightforward in principle but has nuances worth understanding. Starting July 1, 2026, the only date labels permitted on consumer-facing packaging are:
- “BEST if Used By” (or “BEST if Used or Frozen By”)
This indicates peak quality and potency. The product may still be safe to consume after this date, but efficacy or quality may have declined. - “USE By” (or “USE By or Freeze By”)
This is a safety indicator signaling the product should not be consumed after this date.
That’s it. Any variation — “sell-by,” “expires on,” “freshest by,” or any similar phrase — is no longer legal on consumer-facing labels in California. The state estimates there are currently more than 50 different date label phrases in use across the U.S., a fragmented landscape that has long confused consumers and contributed to billions of pounds of unnecessary waste annually.
Why This Matters More for Supplements Than You Might Think
For food brands, the date label conversation is primarily about food safety. For supplement and vitamin brands, it’s really about potency and consumer trust. When a customer sees an ambiguous date on a product like CoQ10, fish oil, Vitamin D3K2, etc., confusion about what that date means can drive returns, undermine brand credibility, or lead consumers to discard perfectly effective products.
The shift to standardized “BEST if Used By” language actually aligns well with how quality supplement brands should already be communicating shelf life. It signals a committment to quality: your product was formulated and tested to deliver on its label claims through a specific date.
What This Means for Brands Not Yet Compliant
For supplement companies ensuring they have a compliant contract manufacturer is imperative to manage the potential disruption this kind of regulatory change can cause. Compliance isn’t just about printing new labels — it requires auditing your entire product line for non-compliant date language, updating artwork files, coordinating with your co-manufacturer, and ensuring compliant inventory is in the pipeline before the deadline.
How Icelandirect Keeps Clients Ahead of Changes Like This
Regulatory compliance is manufacturing function that doesn’t generate revenue directly — but non-compliance can destroy it. Icelandirect monitors labeling regulations as part of our core service model so our clients don’t have to. When changes like AB 660 occur, we adapt our processes proactively, not reactively.
Our labeling operations are already aligned with California’s new date label standards. If you’re an Icelandirect client with supplement or vitamin products shipping into California, you have one less item on your compliance checklist and one more reason to focus on what actually moves the needle: product innovation, customer acquisition, and revenue growth.
If you’re not yet working with Icelandirect and have questions about AB 660 compliance for your supplement line, we’d welcome the conversation. Navigating regulations like this on behalf of our clients is exactly what we do!
