Terpenes, Moisture and Quality

Total Terpene percentages and moisture content by strain and treatment condition is shown in Table 1. Average total terpene content was comparable  between the two microbial reduction methods, with variability driven more by strain - to- strain differences than by treatment effects. Some strains showed slightly higher terpene retention following RF treatment, while others were marginally higher under X-ray treatment, indicating no consistent directional loss associated with RF processing.

Average moisture content remains stable and comparable between RF and x-ray samples. Differences observed among samples were within the normal variation of moisture content of flowers within one lot. All samples retain their moisture content post treatment.

For products marketed on aroma, and sensory quality,  maintaining terpene content and moisture levels  is an important aspect of quality control, as these attributes contribute to product aroma, texture, and overall consumer acceptance. Collectively, these results indicate that RF treatment preserved moisture and terpene content within ranges considered commercially and organoleptically acceptable to consumers.

Germany’s Import Curve Didn't Climb, It Leapt

BfArM-tracked imports show a market that went from growing gradually to increasing dramatically after CanG was passed. ²

The jump from 2024 to 2025 matters. Imports hit roughly 142 tonnes in the first nine months alone, including 56.9 tonnes in Q3. The 2026 estimate assumes growth slows from the 2.6x jump (2024 to 2025) down to something closer to 1.3–1.5x as the market matures and regulatory pacing acts as a brake. ²

That shift changes the bottleneck for exporters and processors. The limiting factor stops being "can you grow it?" and becomes "can you clear EU-GMP processing, meet microbial regulatory compliance, and provide repeatable quality at scale?”

Most operators underestimate this until they stumble and miss a step.

What the Export Market Looks Like in 2026

By late 2025, the supply chain consolidated: Canada anchors supply at nearly half of total imports, Portugal functions as the main European processing and export hub, and a widening set of smaller origins fills in behind them. ⁴

Germany’s Cannabis Supply Chain in Practice

The clean version: cultivate to GACP standards, process to EU GMP standards, clear quality specs, import efficiently under BfArM regulatory controls through pharmaceutical wholesalers, and dispense through pharmacies. ⁵

The real version? Potential friction points happen along the way, and they are tedious and expensive.

• Microbial failures trigger rework
• Irradiation approvals for ionizing treatments (AMRadV) take months and cost thousands
• Batch documentation gaps delay release

What Germany's 2025 Import Approvals Tell You About 2026 Planning

In September 2025, Germany reached its narcotics import ceiling of 122 tonnes as determined under UN treaty guidelines, set annually. BfArM confirmed that while this did not constitute an outright import ban, new applications faced significant processing delays. Imports for cannabis, still recognized as a narcotic by the UN treaty, could not be licensed until the quota was adjusted. After a 2-month delay, the ceiling was increased to 192.5 tonnes and import licenses again started to flow. ⁶

The read for 2026 planning isn't "Germany will shut the door." It's that the system is capacity-managed, and import planning needs to factor in this constraint.

Why Selecting the Right Microbial Decontamination Technology Matters Even More When Exporting to Germany

As volumes increase, operational efficiency and inventory turnover drive profitability for all stakeholders in the supply chain.  Any misstep that slows down product along the supply chain is sand in the gears.

Firstly, Germany has a bias against ionizing radiation - gamma and X-Ray.  BfArM requires any strain treated with ionizing radiation to be registered.  The AMRadV registration process costs time (6-12 months) and money (€5,000 per strain).

Secondly, decontamination with ionizing radiation is expensive, whether performed on-site (X-Ray) or off-site (gamma).  X-Ray is slow, and sending product off-site is not only expensive, but adds another layer of administrative complexity.

Ziel’s decontamination solution uses radio frequency, a non-ionizing radiation that avoids the AMRadV registration requirement. It also has the highest throughput, resulting in the lowest processing cost per gram: less than one fourth the cost of the ionizing alternatives.

Smart operators exporting to Germany are incorporating Ziel’s non-ionizing kill step into their SOPs, streamlining import processes, getting their product on the shelves faster, and positioning their business operations with a scalable technology.

Ziel’s radio frequency solution is rapidly becoming the technology of choice for exporters targeting Germany, with customers in Canada, Portugal, Denmark - the leading suppliers to Europe’s largest market.

What Exporters Planning for Increased 2026 Germany Volumes Need to Know

If your goal is to supply Germany's medical channel in 2026, treat these as non-negotiable:

EU GMP facilities need to have scalability to meet increasing demand

Successfully coming through your EU GMP audit doesn't mean you can handle 3x the throughput six months later. This is where scalability matters. Invest in a high-throughput, EU GMP-compliant decontamination technology to integrate into your SOPs so you can keep up with increased demand. 

A decontamination solution is part of your SOPs.

Using Ziel's Business Case Calculator, cultivators can determine how much revenue RF can recover by increasing harvest yields, avoiding compliance failure, and eliminating the need to send contaminated product off to extraction. This also eliminates subsequent costs for retesting.

What's Changing Heading Into the Rest of 2026

Germany's medical market mechanics shifted following CanG, with the law removing cannabis from narcotics classification, eliminating the burdensome administrative requirements for prescribing doctors, wholesalers, and pharmacies. Telemedicine increased ease of access for patients, removing the initial in-person doctor visit.  And mail order resolved distribution gaps. Taken all together, it supercharged demand in 2025. ³

In 2026, legislation is under review to rein in telemedicine, require in-person doctor visits, and restrict mail delivery—any or all of which could slow the pace of growth

Why It Matters: Ensuring Clean and Organic-Compliant Cannabis

To reach today’s market, cultivators must meet regulatory limits for heavy metals, pesticides, and microbiological contamination. While heavy metals and pesticide compliance are often addressed through sourcing and cultivation controls, microbial contamination remains a persistent challenge.^⁷,⁸,⁹

Mold, yeast, and bacterial failures can reduce harvest yields, delay time to market, and impact profitability. At the same time, cultivators aim to preserve potency, aroma, flavor, and visual quality. Some decontamination methods can meet microbial targets but introduce tradeoffs. Gamma irradiation, for example, is effective for sterilization and used in certain medical markets, but requires labeling and may reduce volatile terpenes.^¹

RF remediation offers a non-ionizing, chemical-free alternative that reduces microbial contamination while maintaining the flower’s natural chemical and sensory profile.^³,⁴,⁵

As the cannabis industry continues to mature, demand is trending toward validated, non-ionizing decontamination technologies that support quality-driven and organic-compliant production standards. Ziel’s decontamination solutions operate commercially throughout the European Union and North America, building on a long-standing foundation in regulated food processing applications.

What Is Good Agricultural and Collection Practice (GACP)?

GACP sets the foundation for cannabis quality by defining cultivation and harvest standards.

• Avoiding contamination: Farmers must monitor soil, water, and nutrients to keep out pesticides, mold, and heavy metals.
• Consistency across crops: Standardized methods produce flowers with predictable cannabinoid and terpene levels. This is essential for doctors prescribing cannabis as medicine.
• Traceability from seed to harvest: Every plant is documented, creating a verifiable history for inspectors.
• Imports must comply too: Since Germany imports much of its cannabis, all imported cannabis must also be grown in GACP-compliant facilities.

What Is Good Manufacturing Practice (GMP)?

Once harvested, cannabis must be treated like a pharmaceutical product. GMP governs post-harvest handling.

• Controlled spaces: Processing areas must be clean and tightly monitored to prevent contamination.
• Documented procedures: Every step, from drying times to packaging, must be written, followed, and reviewed.
• Quality management: Processes must be validated, deviations logged, and performance reviewed over time.
• Safe distribution: Good Distribution Practice extends protections into storage and transport, ensuring cannabis remains stable until it reaches pharmacies.

Without GMP certification, cannabis cannot be sold in Germany's medical market.

What Is the Role of European Pharmacopoeia?

The European Pharmacopoeia (Ph. Eur.) serves as the official rulebook for medicines across Europe. Its Cannabis Flower Monograph sets the final product requirements.

• Potency standards: THC and CBD content must be within 10 percent of the labeled value.
• Purity requirements: Strict limits apply for heavy metals, and low moisture levels reduce mold risk.
• Physical appearance: Flowers must be free of seeds and large leaves, with only minimal foreign matter allowed.

Harmonized rules across Europe: Shared standards smooth the flow of imports and exports and give patients consistent quality across the EU.

How GACP, GMP, and the Pharmacopoeia Work Together

Think of these standards as a three-step safety net:

1. GACP: Defines how the plant is grown and harvested.
2. GMP: Regulates processing, testing, and packaging.
3. Ph. Eur.: Confirms the finished product before it reaches pharmacies.

Together, they create full traceability. If an issue arises, regulators can track a product back to the exact harvest and facility.

Cannabis in Europe by the Numbers (2025 Estimates)

What the Numbers Show

• Germany dominates as Europe’s largest medical cannabis market, with imports doubling in 2024.
• The UK continues rapid growth, supported by telehealth adoption and domestic cultivation.
• Poland, Portugal, and Denmark are smaller but strategically vital markets, supplying Germany and other EU states.
• Switzerland is pioneering adult-use pilots, already recording €23.7 million in sales.
• The Czech Republic has begun to scale exports, signaling its intent to grow as a supplier.

This growth represents more than opportunity. As volumes expand, the risks of contamination, recalls, and compliance failures also grow.

Ziel: Setting the Remediation Standard

Ziel's role in Europe's cannabis future is clear:

• Safety at scale: Eliminating harmful microbes without damaging cannabinoids or terpenes.
• Compliance made simple: Meet Pharmacopeia standards with flexible recipe settings
• Value protection: Preserving flower quality in markets where price competition is intensifying.
• Cross-border confidence: Giving regulators and importers assurance that products meet the highest quality standards, without having to register strains with AmRadV in Germany.

As Europe's cannabis market races toward multi-billion-euro growth, Ziel ensures the foundation is strong, safe, and scalable. Without it, the numbers are just numbers. With Ziel, they become a roadmap to a secure and thriving industry.

Why Portugal Became the GMP Processing Hub

• Progressive drug policy: In 2001, Portugal became the first country in the world to decriminalize all personal drug use, including cannabis.
• Legalization framework: Cannabis was legalized for regulated uses in 2018, with implementation guidelines finalized in 2019.
• First international export: Portugal’s first cannabis shipment took place in 2019, when 500 kilograms were exported by Tilray to Germany.
• Regulatory efficiency: Oversight by Infarmed encouraged foreign investment and positioned Portugal as an EU-compliant export hub.

Understanding the GACP-to-GMP Gap

GACP governs everything from seed propagation to harvest. It ensures plants are grown consistently, safely, and in line with WHO guidelines. But GACP only covers part of the chain to market.

GMP begins after harvest. It includes bucking, drying, trimming, microbial decontamination, testing, and final packaging. Without a local GMP-certified option, GACP growers must outsource their GMP processing, either in their own country or, more likely, an EU-based GMP Processor. This is why many producers in countries like Thailand and Colombia have relied on Portugal to meet the GMP processing required for exporting to the largest European markets, Germany and the UK. This system works, but adds significant cost and complexity for the producer and cuts into their profit margins.

Growers Are Shifting to In-Country GMP

Growers have built large-scale cultivation sectors around GACP compliance, which is essential for EU entry. Now, they’re also incorporating GMP compliance into their operations. Both Thailand and Colombia are strong examples of this shift to in-country GMP processing.

In Thailand, the evolving regulatory landscape supports a growing export sector. Producers are increasingly looking to build more control into their operations to leverage this and have started investing in GMP processing locally.

In Colombia, ideal growing conditions and a well-established GACP framework have positioned the country as a major flower supplier, and growers there are also starting to incorporate GMP locally.

The global trend is clear. Instead of relying on GMP Processors in Portugal, more growers are choosing to bring post-harvest compliance into their own facilities. Ziel makes this transition possible.

What Ziel RF Remediation Delivers

Ziel’s Radio Frequency (RF) remediation systems allow growers to meet strict EU microbial safety standards in-house. The technology uses non-ionizing energy to reduce total yeast and mold counts by more than 99.9 percent, without using ionizing radiation, gas, or chemicals.

Key Benefits of Ziel’s RF Technology Include:

• Meets EU Pharmacopeia Standards
• Avoids labeling and registration issues related to irradiation in Germany, like the AmRadV license
• Preserves terpenes, aroma, and cannabinoid profiles
• Compatible with organic certification
• Compact design with fast cycle times for high-throughput processing
• Commercially proven and validated under EU GMP standards
• Technology has been commercially used and validated in the food industry for over 20 years

Meeting Global Standards

The European Union’s 27 countries represent one of the largest potential markets, with more than 350 million people. Leveraging this market by exporting cannabis to the EU involves strict compliance with agricultural and manufacturing standards.

European regulators apply pharmaceutical-level standards to their cannabis market, which set tight limits on yeast, mold, and bacteria. In practice, every crop must pass strict safety tests before it can reach patients. Producers have to maintain very low microbial counts and adhere to the EU’s Good Agricultural and Collecting Practices (GACP) and Good Manufacturing Practices (GMP), as well as to individual country requirements. For example, in Germany, each cannabis strain treated by ionizing radiation requires a separate registration, a costly obstacle our Radio Frequency (RF) approach avoids.

The EU does not have a single cannabis monograph, so growers must adapt broad pharma microbiology requirements. Colombian producers planning to enter the EU market need to build these requirements into their operations from the beginning, including thorough testing and reliable records.

Microbes: A Hidden Risk

Mold, yeast, and other pathogens are serious risks in cannabis production, especially in warm and humid climates like Colombia’s. The same conditions that support strong plant growth also encourage mold. Mold can develop during drying or storage, and even properly dried flower can become contaminated if humidity changes.

Regulators test for total yeast and mold (TYMC), total bacteria (TAMC), and pathogens such as Aspergillus or Salmonella. If a batch exceeds limits, it must be reworked or destroyed, which cuts into profits. Contaminated cannabis might have to be converted into extract products, which usually hold less value. We’ve seen many producers forced to shift product to lower-value extracts, a result that effective remediation can help avoid.

Radio Frequency Remediation

Ziel uses Radio Frequency technology to support safe and effective cannabis remediation. RF energy is non-ionizing, which means it does not change the chemical structure of the plant. Instead, RF waves oscillate water molecules within the flower, creating volumetric heating that kills mold and bacteria while maintaining product quality. Our RF system can reduce yeast and mold counts by over 99.9%, allowing producers to save harvests and avoid major losses. Unlike traditional, ionizing methods like X-ray or E-Beam, RF treatment is non-ionizing and does not require special labeling or licensing.

Safe, Organic Treatment

We are committed to providing a safe and organic process. Ziel’s machines require only a food-grade nylon bag and minimal electricity per cycle, producing no chemical residues or impact on the plant’s sensory qualities. The RFX and APEX 7 can run continuously with no required downtime, making them practical solutions for high-volume producers.
