Germany’s Sixth NpSG Amendment — and the 0.3% That Means Three Different Things

December 2025’s second amendment to Germany’s New Psychoactive Substances Act closed a drafting gap and reshaped what hemp businesses must track: a 0.3% threshold that is measured differently depending on law, analyte and stage of production.

Germany’s Sixth NpSG Amendment — and the 0.3 % That Means Three Different Things

Useful takeaways from this story.

Germany’s NpSG now defines banned semi-synthetic cannabinoids by structural classes, allowing regulators to capture successor molecules without listing each substance.

The 0.3% THC figure in German consumer cannabis law applies to the source plant or variety (or alternatively to certified EU varieties), not explicitly to delta-9-THC or the finished product.

Austria and Switzerland treat similar percentages differently: Austria applies a product limit across production, while Switzerland counts average total THC (including THCA) with a 1.0% threshold.

# What changed in Germany

# Why the drafting technique matters

By legislating against structural classes instead of naming each molecule, regulators avoid having to schedule every new analogue. That means a regulator can capture broad categories of semi-synthetic cannabinoids and does not have to chase the market substance by substance. For advisers, that undercuts the idea that each new analogue will reliably buy a year or more of legal trading.

# What the 0.3% figure actually means in Germany

  • The certified-variety route and the 0.3% route are alternatives, not cumulative requirements. Either route can be used to evidence lawful origin.
  • The statute refers to "tetrahydrocannabinol" without naming an analyte. It does not specify delta-9-THC or total THC.
  • The threshold applies to the source material—the plant or variety—rather than explicitly to the finished product on the shelf. Evidence in practice is supplier documentation: variety certification or plant analysis.

A certificate of analysis on a finished product is useful but not what the statutory wording requires. The law also conditions the definition on excluding use for intoxication, a factual and enforcement question that lab reports cannot settle by themselves.

# Switzerland differ

Austria's Suchtmittelverordnung sets a genuine product threshold: the limit must not be exceeded before, during and after production. That means concentration steps in processing can breach compliance even when starting material met a 0.3% plant threshold.

Switzerland's BetmVV-EDI defines controlled cannabis beginning at an average total THC content of 1.0%, explicitly counting total THC (so THCA is included). Unheated flower often has a THCA-dominant profile, which changes the compliance picture compared with a delta-9 reading.

# Practical compliance consequences

For cross-border sellers the compliance question is not simply whether a product is under 0.3%. It is: which analyte (delta-9, THCA, total THC), measured at which stage (source plant, intermediate, finished product), against which legal instrument in each destination market. A standard EU certificate of analysis may not answer Austria's or Switzerland's test.

Advisers should reframe client checks around mapping destination-specific measurement rules, documenting source-material provenance, and treating the exclusion-of-intoxication requirement as an operational and evidentiary issue rather than solely a lab result.

# Bottom line
