California Food Date Labeling: Compliance Guide for Spice Trade

As of July 1, 2026, California has implemented Assembly Bill 660 (AB 660), establishing a mandatory standard for date labeling on food products sold within the state. This legislative pivot aims to eliminate consumer confusion surrounding varying labels and reduce systemic food waste, which has long plagued the industry. For stakeholders in the premium spice trade—including importers, distributors, and private-label buyers—this represents a critical shift in packaging compliance. Understanding the distinction between peak quality and safety-based timelines is essential for maintaining supply chain integrity and brand trust. By moving away from a fragmented landscape of "sell-by," "enjoy-by," and "freshest-by" labels, California is setting a precedent that prioritises transparency, ensuring that consumers can distinguish between a product that is past its prime and one that is no longer safe to consume.

Navigating the New Standards

The core of the legislation is the replacement of inconsistent terminology with uniform, clear language. Manufacturers must now utilise specific, regulated phrases. For products where the date reflects peak freshness and sensory quality, labels must read "BEST if Used by" or "BEST if Used or Frozen by." Conversely, when a date is dictated by strict safety parameters, the law requires the usage of "USE by" or "USE by or Freeze by."

This standardisation provides a clear framework for the industry. While retailers are permitted to continue using coded inventory management systems for internal rotation, these codes must not be displayed in a manner that creates consumer-facing ambiguity. According to California Legislative Information, the focus is on clarifying the difference between the deterioration of volatile oils in spices and potential food safety concerns. For those managing products, this requires an immediate audit of existing packaging to ensure full compliance with the California market. Failure to align labels with these specific phrases is no longer merely a branding oversight; it is a regulatory violation that could result in stop-sale orders or significant administrative friction.

The legislation also mandates that these dates be displayed in a clear and conspicuous manner. For spices, which often utilise smaller packaging, this requires careful consideration of font size and placement. Labels must be legible to the average consumer, preventing the common practice of burying date information in obscured or cluttered sections of the packaging.

The Impact on Spice Provenance and Quality

At Treedha, we view these regulations through the lens of provenance and purity. Spices are defined by their essential volatile oils; their flavour profile is a living metric of their origin and handling. The new "BEST if Used by" labelling provides an authoritative, state-sanctioned way to communicate to chefs and home cooks that our ground cumin or Kashmiri chilli powder is at its peak.

By codifying these dates, the industry can better educate the end-user. A spice that has passed its "BEST if Used by" date is not inherently dangerous, but it may lack the vibrant, characteristic notes that define our sourced ingredients. Our commitment to steam-sterilisation ensures that products arrive in pristine condition, yet shelf-life remains a product of natural physics. Oxidation, light exposure, and fluctuations in ambient temperature are the primary enemies of high-grade spices. This law helps align consumer expectations with the inherent shelf-stability of high-grade natural ingredients, protecting the brand equity of premium importers who prioritise flavour intensity over long-term shelf endurance. By explicitly labeling for "Best" quality, we encourage consumers to enjoy our spices when they are most potent, rather than holding onto them long after their terpene profiles have degraded.

Operational Compliance for Importers

For distributors and wholesale partners, compliance with AB 660 is not optional. The legislation applies across the distribution chain, meaning liability extends beyond the original manufacturer. Ensuring that labels are accurate and compliant is a core component of risk management. As outlined by the EAS Consulting Group, failure to align with these requirements can lead to regulatory scrutiny and unnecessary penalties.

For the importer, this means a rigorous review of labelling processes at the point of origin or the point of entry. If you are importing bulk spices that are then repacked or private-labelled, you must ensure that your facility or your third-party co-packer is fully integrated into the AB 660 workflow. We recommend that all partners review their current stock against these new standards. If your inventory involves diverse categories such as grains or pulses, assessing the shelf-life markers against the new "USE by" safety criteria is a prudent step in safeguarding your business reputation. Proper documentation and transparency—the hallmarks of Treedha's sourcing model—are now, more than ever, the industry standard for success in the California market.

Compliance audits should now be a standard component of quarterly quality assurance reviews. Distributors must ensure that incoming documentation reflects these labels, and retailers must ensure that no non-compliant legacy stock remains on shelves. Clear labelling is not just a legal requirement; it is a signal of operational excellence.

Comparison of Date Labeling Applications

When comparing these applications, it becomes clear why AB 660 is a necessary evolution. Many historical labels, such as "Sell by," were essentially retailer-facing tools that confused consumers into throwing away perfectly usable products. By moving the focus toward "BEST if Used by" for quality and "USE by" for safety, we provide the consumer with a binary choice that respects the integrity of the product.

For many spices, a "USE by" date may never actually be reached, as the quality ("BEST if Used by") will degrade long before the product presents a safety risk. This distinction is vital for chefs and restaurant procurement teams, as it allows for better inventory management—ensuring that the most flavourful product is always in use, while maintaining absolute compliance with state safety guidelines.

Maintaining a clear, compliant supply chain is the most effective way to honour the origin and quality of the ingredients we share. As the industry moves forward, we remain committed to providing not only the finest spices but also the regulatory clarity required to navigate this changing landscape successfully. By proactively adopting these standards, we reinforce our dedication to transparency, food safety, and the unmatched quality of the products delivered to your kitchens. We encourage all stakeholders to use this legislative transition as an opportunity to refresh their inventory practices, ensuring that every bag and jar that leaves our facilities is a testament to the uncompromising standards of the modern spice trade.
