Kratom in the new PML legal framework

Since November 2025, a major legislative change came into force in the Czech Republic. Under Act No. 321/2024 Coll., kratom (Mitragyna speciosa) was classified as a psychoactive modulating substance (PML). This step ended the period of an unregulated market and introduced strict rules for its distribution, storage, and labelling. Kratom is no longer considered ordinary goods but a substance subject to supervision by the Czech Agriculture and Food Inspection Authority (SZPI), ensuring greater transparency and product safety on the market.

Classification system: Colour as a mandatory “subtype”

Within the new legal framework, colour designation is no longer just a marketing name but becomes a legal requirement for product identification. According to Decree No. 448/2025 Coll., the label must follow a precise hierarchy of data, where colour is defined as a “subtype” of the substance. This precise terminology is key for traceability of each batch and its correct registration in the mandatory electronic system.

Technical and alkaloid specification of colour subtypes

The main technical difference between subtypes is their analytical profile, defined by the content of major alkaloids – especially mitragynine and 7-hydroxymitragynine. Legislation sets a limit of a maximum of 1,250 mg of mitragynine and 50 mg of 7-hydroxymitragynine per 50g package. Analyses in accredited laboratories, such as BAFA at the University of Chemistry and Technology, confirm the following parameters of individual subtypes:

Green kratom: Technically shows the highest mitragynine concentration, reaching up to 1.6% (w/w) in selected batches (e.g. L20261002).

White and yellow kratom: These variants show stable values in the range of 1.4% to 1.5% mitragynine.

Gold kratom: Analytical measurements (e.g. batch L20264001) confirm a mitragynine level of 1.4% (w/w).

Red and brown kratom: From a technical perspective, these subtypes have a lower mitragynine content, usually in the range of 0.7% to 0.9%.

Permitted colour subtypes on the Czech market

The current regulatory system allows distribution of six basic colour subtypes in the Czech Republic: green, white, yellow, red, brown, and gold. Each of these products must undergo testing for contaminants under strict limits:

• Heavy metals: Maximum allowed levels for arsenic (0.5 mg/kg), lead (3.0 mg/kg), cadmium (1.0 mg/kg), and mercury (0.1 mg/kg).
• Microbiology: Screening for Salmonella (must be negative), E. coli, and limits for moulds and yeasts.

Technical aspects of processing and botanical origin

Kratom from Plody země comes from wild-growing trees in Indonesia. The production process takes place in hygienically certified facilities, where raw material in 1 kg vacuum bags is disinfected and then repackaged into final 50g packages.

An important technical step ensuring purity is gamma irradiation treatment. Although laboratory analysis cannot retrospectively prove whether the treatment was applied, its use is highly recommended to eliminate unwanted microflora and ensure safety of each colour batch. Each batch is then labelled with a unique code (starting with the letter “L”), accompanying the product throughout the entire process from production to final sale.

Conclusion: Transparency and safety through precise labelling

The introduction of a clear classification system and mandatory testing in accredited laboratories raises the overall industry standard. Plody země is based on an individual approach and guarantees that each subtype meets not only visual requirements but also strict analytical limits for purity and alkaloid profile. Transparent labelling is therefore key to sustainability and safety within the new market for psychoactive modulating substances.
