Hemp Product Labeling Under the Federal Standard: What Must Appear on the Package

Finished product labeling is where hemp compliance becomes visible to consumers, retailers, and regulators. Under the November 12 federal standard, hemp-derived cannabinoid products must meet specific labeling requirements — and brands that have not updated their labels to reflect the new framework are creating compliance exposure even if their formulations and ingredient sourcing are fully compliant.

The Core Labeling Requirements

1. Total THC Disclosure

The November 12 standard requires that hemp-derived cannabinoid products disclose total THC content on the label. This disclosure must reflect the total THC calculated using the standard formula (delta-9 THC + THCA × 0.877), not just delta-9 THC alone.

Brands that currently label products as "<0.3% delta-9 THC" or "0mg THC" without disclosing total THC are non-compliant with the labeling requirement even if the delta-9 THC content is accurate. The label must show the total THC figure.

The total THC disclosure should specify:

• The amount in milligrams per container (the compliance threshold is 0.4mg per container)
• The serving size basis if the label also lists per-serving cannabinoid content

2. Cannabinoid Content Disclosure

In addition to total THC, hemp product labels must disclose the cannabinoid content of the product. Minimum required disclosures typically include:

• Primary cannabinoid(s) by concentration (e.g., CBD 25mg per serving)
• Total cannabinoid content per container where applicable
• Whether the product contains full spectrum, broad spectrum, or isolate hemp extract

Labels that list only CBD content without total THC, or that describe the product as "hemp extract" without cannabinoid specifics, are insufficient under the federal labeling framework.

3. Testing Documentation Reference

While the COA itself is not printed on the label, the November 12 framework encourages (and some state laws require) that hemp product labels include a reference to how consumers and retailers can access the product's COA. This typically takes the form of:

• A QR code linking to the COA for the specific lot
• A batch/lot number that can be used to look up the COA on the brand's website
• A URL where COA documentation can be accessed

For B2B ingredient buyers whose customers are finished product brands, the lot number on the ingredient COA should trace through to the finished product lot number and ultimately to the retail label.

4. Net Weight and Serving Size

Hemp products must comply with standard food labeling requirements for net weight and serving size under FDA's food labeling regulations (21 CFR Part 101). For cannabinoid products, serving size is particularly important because the 0.4mg per container limit must be evaluated at the container level — which means the serving size and servings per container must support accurate consumer calculation of cannabinoid intake.

5. Manufacturer Information

• Legal name and address of the manufacturer or distributor responsible for the product
• Contact information for consumer inquiries
• For dietary supplement formats: compliance with FDA's dietary supplement labeling requirements including structure/function claim disclaimers where applicable

6. Hemp Source Declaration

Labels should clearly indicate that the product is derived from hemp (Cannabis sativa L.) produced under USDA hemp program licensing or an approved state plan. This declaration distinguishes the product from marijuana-derived products and is a baseline compliance statement.

What Must NOT Appear on Labels

Disease treatment or drug claims. As discussed in the FTC warning letter article, labels may not claim that the product treats, cures, or mitigates specific medical conditions. This applies equally to label text and to imagery or symbols that imply medical use.

"THC-free" claims without qualification. Products labeled as "THC-free" that contain detectable THCA are making a potentially misleading claim — THCA can convert to THC, and under the total THC standard, THCA contributes to compliance calculations. "Non-detect" claims should reference the specific test and the detection limit of the laboratory method used.

Synthetic cannabinoid identity claims. Products may not be labeled as containing delta-8 THC produced from isomerization, HHC, THC-O, or other synthetic cannabinoid derivatives if sold as hemp-compliant products under the November 12 framework.

State-Specific Labeling Requirements

State labeling requirements vary and in some cases are stricter than the federal standard. States that have aligned with the federal framework (Virginia, New Jersey) have adopted labeling requirements consistent with the federal standard. States with different compliance frameworks (Kansas's intoxicating product prohibition, Georgia's synthetic cannabinoid prohibition) may impose additional labeling requirements. Multi-state brands should audit their labels against the specific requirements of each state in their distribution footprint.
