Labeling Claims for THC-Free CBD Products

What this page covers: Practical, compliance-minded guidance for making truthful, verifiable “THC-free” or “non-detectable THC” labeling claims on CBD products, including COA/LOQ basics, recommended wording, common pitfalls, and a launch checklist.

What this page doesn’t cover: Full regulatory frameworks or enforcement procedures (see the site’s Compliance hub for overarching rules) and detailed legal advice for specific jurisdictions. For legal strategy and binding interpretations, consult a qualified attorney or regulator.

Short note on the broader Compliance context

This page focuses on labeling claims and claim substantiation. For the wider regulatory, registration, and enforcement topics that affect labeling, see the Compliance section at /compliance. This article intentionally summarizes those connections in 1–3 sentences and does not duplicate the Compliance hub’s broader coverage.

Key definitions

THC-free: A marketing claim asserting that a product contains no measurable tetrahydrocannabinol (THC). Because absolute zero cannot be analytically proven, responsible claims are qualified by method and threshold.
Non-detectable / Not detected (ND): The lab did not detect THC above the method’s limit of detection (LOD). ND statements should reference the LOD or LOQ.
Limit of Detection (LOD): The smallest concentration that a test can reliably distinguish from zero but not necessarily quantify precisely.
Limit of Quantitation (LOQ): The lowest concentration at which the analyte can be quantified with acceptable accuracy and precision. LOQ is the preferred threshold for labeling statements.
Certificate of Analysis (COA): A lab report showing test results for cannabinoids (including delta-9 THC), residual solvents, pesticides, and other analytes. COAs substantiate labeling claims.

Principles for truthful, defensible labeling claims

Substantiate every THC-related claim with a recent, batch-level COA from a reputable third-party lab (preferably ISO/IEC 17025-accredited).
Use numeric thresholds and testing context rather than absolute language. Identify the analyte (usually delta-9 THC), the LOQ/LOD, the lab name, and the date of testing.
Avoid medical or performance claims. Stick to product composition and testing statements.
Consider consumer safety and drug-testing risk: even low/ND THC levels can vary between batches, and cross-contamination is possible.

Recommended wording examples (and why they work)

Choose language that is specific, verifiable, and not absolute. Examples:

“Third‑party tested for delta‑9 THC: not detected at LOQ 0.01% (COA dated YYYY‑MM‑DD).” — Provides analyte, threshold, and provenance.
“Contains < 0.01% delta‑9 THC per COA (batch #XXXX)." — Numeric, tied to a COA and a batch.
“Manufactured to be THC-free; third‑party testing shows delta‑9 THC below the lab LOQ (COA available).” — Avoids an absolute zero claim while promising documentation.

Avoid blanket statements like “0% THC” or “guaranteed THC-free” unless you can substantiate them with rigorous, validated testing and accept the legal risk in your jurisdiction.

COAs, LOQ and practical testing guidance

How to use COAs in labeling:

Prefer batch-level COAs that match the specific product lot, not a certificate for a single sample from a broad production run.
Display or link to the COA where consumers can easily verify the batch number, analytes, LOQ/LOD, and the testing laboratory.
Verify the testing method and accreditation. ISO/IEC 17025 accreditation, clear reporting of LOQ/LOD, and chromatograms for cannabinoids increase credibility.

LOQ vs. LOD: For labeling, LOQ-based statements are stronger because they indicate quantifiable absence below a reproducible threshold. If a COA reports “ND” it should state the LOQ or LOD so the claim has context.

Pitfalls and enforcement risks

Unsubstantiated absolute claims: Saying “zero THC” without COAs or method context invites regulatory action and consumer complaints.
Inconsistent batch testing: Using a single test for multiple batches or failing to link COAs to lot numbers undermines claims.
Non‑accredited labs or opaque methods: Unsupported COAs are weak evidence in disputes or enforcement.
Misleading qualifiers: Small-print qualifiers that contradict the main label (e.g., burying a disclosure that THC may be present) can be considered deceptive.
Drug testing risk: No labeling statement can guarantee a consumer will not test positive for THC. Never imply a product is guaranteed to prevent positive drug tests.

Practical pre-launch labeling checklist

Obtain a batch-specific COA from a credible third-party lab; confirm LOQ/LOD and the analytes tested (including delta‑9 THC).
Draft label wording that cites the COA date, lab name, analyte, and LOQ threshold if claiming “THC-free” or “non-detectable.”
Include standard mandatory product information: net weight, serving size, cannabinoid potency per serving, ingredient list, manufacturer/distributor contact, batch/lot number, manufacture/expiry dates when required.
Add consumer risk language about potential drug-test detection and storage/usage instructions where relevant.
Post the COA or a clear link/QR code to the COA on your website or packaging for consumer verification.
Have labeling reviewed by legal and compliance advisors familiar with local laws and advertising rules.

Frequently asked questions (FAQ)

1. Can I label my product “THC-free”?

You can use a “THC-free” style claim if it is truthful and substantiated. Best practice is to qualify the claim with testing context (e.g., “not detected at LOQ 0.01% per third‑party COA dated YYYY‑MM‑DD”) and ensure a matching batch-level COA is available. Exact permissibility varies by jurisdiction.

2. Is “non-detectable” the same as zero THC?

No. “Non-detectable” means the lab did not detect THC above its method LOD/LOQ. It does not prove absolute absence of molecules; it documents that THC was below the laboratory’s reporting threshold.

3. Will a “THC-free” label prevent a positive drug test?

No labeling statement can guarantee a negative drug test. Drug-test results depend on test sensitivity, product variability, metabolism, and usage. Include clear consumer warnings about drug-test risk where appropriate.

4. How often should I test to support labeling claims?

Test each production batch that will be sold under a given label claim. Relying on a single representative test for many batches increases risk; frequency requirements may also be set by local law.

5. What lab credentials should I look for?

Prefer ISO/IEC 17025-accredited labs with experience in cannabinoid analysis. Confirm they report LOQ/LOD values and provide chromatograms and full-method descriptions upon request.

6. Can I use a COA that reports delta-9 THC but not other isomers like delta-8?

Be explicit about which analytes were tested. If you claim a product is “THC-free” but only tested for delta‑9, that is potentially misleading. Consider testing for all relevant THC isomers and impurities, or limit the claim wording accordingly.
