The New Era: Weights & Measures Scrutiny for Hemp Retail in 2025–2026
As hemp-derived THC beverages and other hemp products enter the mainstream grocery and convenience marketplace, a wave of new compliance priorities has emerged—specifically, the arrival of weights and measures audits at the retail level. From net contents declarations to shelf price scanners, the cutting edge of hemp retail compliance in 2025 now integrates rules and enforcement historically reserved for packaged foods and household goods. This shift is driven by the adoption of updated NIST Handbook 130 and 133 requirements as well as heightened FDA and state oversight for ingestible hemp products.
Why This Matters Now
Over the past year, hemp-THC drinks have moved from boutique shelves to high-volume grocers and c-stores. With this growth comes increased scrutiny—both from state Weights & Measures (W&M) divisions and from private sector quality assurance teams tasked with avoiding the risk of recalls, fines, or damaged relationships with key chains and distributors.
Handbook 130 & 133: Rulebook for Hemp Retailers
Core Regulatory Standards
The National Institute of Standards and Technology (NIST) issues Handbook 130 (Uniform Packaging and Labeling Regulation) and Handbook 133 (Checking the Net Contents of Packaged Goods). In 2025, these rulebooks are directly referenced by most state W&M agencies for packaged hemp beverages:
Net Contents: Dual Declaration Is Mandatory
For beverage products, labels must display net contents in both U.S. customary ("fl oz") and metric units ("mL"). The correct sequence is fluid ounces first, followed by milliliters (example: “12 fl oz (355 mL)”).
Key elements for compliance:
- Location: Net quantity must be on the principal display panel (PDP)—typically, the front of the package, not obscured by shrink sleeves, images, or branding.
- Type Size: Font size must meet the minimum requirement determined by the area of the PDP. For many common formats, this means at least 1/8 inch in height for packages with a PDP under 5 square inches. Larger packages require larger type.
- Readability: No print distortion, and the statement must contrast with background graphics/color.
- No Deceptive Space: Packages cannot have excessive empty space that exaggerates contents visually (e.g., oversized cans with less liquid). FDA and W&M will cite this as “slack fill.”
Scanner Accuracy & Unit Pricing
As hemp beverages become regular inventory in chain retailers, stores are now subject to scanner price accuracy sweeps and unit pricing audits:
- Scanner Accuracy: All shelf or promotional prices must match those scanned at checkout. If a shelf tag says “2 for $5,” the register must reflect this at point of sale. State W&M inspectors run surprise audits—fines and corrective actions follow mis-scanning.
- Unit Pricing: Shelf tags must display price per ounce or per 100 mL/100 g, making comparison shopping possible and preventing hidden price inflation for hemp drinks.
Audit Risks: Common Violations and Their Impacts
Top Compliance Violations in 2025 Audits
- Net Quantity Errors
- Missing the dual declaration (“fl oz” and “mL”) or reversing the order.
- Using non-standard abbreviations (like “fluid oz” or “mililiters”) instead of “fl oz” / “mL”.
- Placing net contents too low or tucked beneath shrink sleeves, graphics, or flavor icons.
- Minimum type size not met, especially with custom artwork or small-format cans.
- Deceptive Packaging
- Packages have visible empty space (slack fill) inappropriate for the size/volume.
- Windows or cutouts used to suggest greater content than is present.
- Scanner and Shelf Tag Mismatches
- Promotional shelf tags or weekly ads do not sync with scanner prices, especially during short-term sales or regional pricing trials.
- Shelf tags lack required unit pricing or display inconsistent units between flavors/brands.
Enforcement Trends
- State W&M offices have increased both announced and undercover inspections, focusing on new hemp-THC beverage categories.
- Retailer response: Chains impose chargebacks or compliance penalties for suppliers whose products generate W&M citations, threatening supplier relationships.
- UDAP Risk: Weights and measures findings can trigger Unfair or Deceptive Acts or Practices (UDAP) complaints, escalating exposure from an administrative citation to full-scale AG or class action scrutiny.
Pre-Audit Checklist for Hemp-THC Beverages
Before your next shipment or planogram reset, use this pre-audit checklist to minimize compliance risks:
Net Contents & Labeling
- Dual declaration is present: Net contents show both fl oz and mL, in the required order
- Correct abbreviations: “fl oz” and “mL” only
- Principal display panel: Net contents placed above the bottom 30% of the PDP, clearly visible
- Font size: Meets or exceeds NIST type size minimums based on label area
- Readable contrast: Statement is not hidden or distorted by shrink wrap, images, or branding
- No deceptive slack fill: Package size closely fits actual beverage volume
Shelf/Unit Pricing & Scanner Accuracy
- Promotional/sale tags: Match scanner price exactly at checkout
- Unit pricing tags: Price per ounce or per 100 mL is displayed, consistent with other shelf tags in the set
- Weekly/time-limited promos: Review that all POS/inventory systems are aligned with advertised prices before starting promotion
- Barcode verification: UPC/barcode is registered to the right SKU/size
What Business Owners and Compliance Teams Should Do Next
Documentation: Maintain current copies of label proofs, W&M certifications (if applicable), and regular scanner/unit price logs—especially for chain accounts.
Vendor Management: Distributors and copackers should review all recipes, yields, and fill lines in view of 2025 rules, as W&M citations at retail often trigger costly investigations up the supply chain.
Training: Store-level and third-party merchandising teams should receive refresher training on net contents placement, scanner accuracy protocols, and spot checks.
Rapid Remediation: Develop (and rehearse) a rapid-response protocol for suspected scanner mismatches or discovered label violations.
The Bottom Line: Don’t Let Minor Mistakes Trigger Major Headaches
Hemp beverage producers, distributors, and retailers must treat W&M compliance not as a box-checking exercise, but as an enterprise-wide, ongoing risk management function. As enforcement ramps up and hemp-THC drinks move deeper into mainstream retail, even minor compliance slips can cascade: state fines, retail chargebacks, and consumer lawsuits all loom.
