Hemp Derivative Import Compliance: EU vs US THC Thresholds for CBD, CBG & CBN

A CBD isolate that clears customs cleanly into the United States can get flagged entering the EU, and the reverse happens just as often. The products aren't different — the compliance regimes measuring them are. For a buyer sourcing wholesale hemp derivatives for more than one market, understanding exactly where those regimes diverge is the difference between a routine shipment and a seized one.

The headline number isn't the whole story

The most commonly cited figures are a 0.3% Delta-9 THC threshold for "hemp" under US federal law (the 2018 Farm Bill definition) versus a 0.2% (in some EU member states, 0.3% as the EU moves toward harmonization) THC threshold under EU frameworks. Treating this as a single number to hit is where buyers get into trouble — the thresholds differ not just in value but in what's actually being measured, how it's measured, and at what stage of the product.

Total THC vs. Delta-9 THC

This is the distinction that causes the most compliance failures. US federal hemp law measures Delta-9 THC specifically. Many state and international frameworks, including several EU testing protocols, measure "total THC" — which accounts for THCA (tetrahydrocannabinolic acid, the non-psychoactive precursor that converts to Delta-9 THC when heated) using a conversion formula. A product that tests compliant under a Delta-9-only measurement can test as exceeding the threshold under a total-THC measurement, because THCA content gets folded into the total. If your supplier's CoA only reports Delta-9 THC and your destination market uses a total-THC standard, that CoA doesn't actually demonstrate compliance for your shipment.

Always confirm which measurement methodology the CoA uses, and cross-check it against what your destination market's customs and regulatory authority actually requires — not just what threshold number gets quoted informally.

Product form changes the risk profile too

Raw hemp paste, crystalline isolate, and water-soluble formulated products carry different compliance considerations even at identical THC percentages, because finished-product regulation (labeling, novel-food status in the EU for ingestible CBD products, cosmetic-use rules) sits on top of the raw-material THC threshold. A crystalline CBD isolate destined for further formulation faces a different compliance path than the same isolate pre-blended into a consumer-facing wellness product — the latter triggers additional finished-goods regulation in most EU markets under novel food rules, which raw isolate for B2B reformulation generally doesn't.

A practical compliance checklist

• Confirm whether your destination market tests Delta-9 THC or total THC, and request a CoA that reports the metric that actually applies.
• Confirm the threshold currently in force for your specific destination country — EU member states have not fully harmonized on a single number, so "EU-compliant" without a country specified is an incomplete claim.
• If the product will be sold as a finished consumer good rather than reformulated further, check novel-food or equivalent finished-product regulation separately from the raw THC threshold.
• Request batch-specific CoAs, not a reference CoA — THC content in hemp-derived isolates can vary batch to batch even from the same supplier and cultivar.

None of this compliance work replaces your own legal review for a specific destination market — thresholds and finished-product rules shift, and a supplier's documentation is a starting point for your own compliance process, not a substitute for it. But asking these specific questions, rather than accepting "EU-compliant" or "US-compliant" as a blanket claim, is what separates a shipment that clears customs from one that doesn't.
