ReLEAF's regulatory review identifies three separate questions: how the agricultural output is classified, how the engineered production culture is contained, and which requirements apply to the bioreactor. The most important finding is that a potential regulatory pathway is not an approval. A fertilizer or plant-biostimulant route is being investigated for ReLEAF's cell-free output, while the classification of the engineered Bacillus subtilis culture and the final equipment requirements remain separate questions.
Our analysis covers Taiwan, the European Union, the United States, and potential Southeast Asian markets. Taiwan is our development and validation environment. Our current commercialization plan prioritizes the Philippines as the first international expansion market, with the European Union considered for a later stage.
The review draws on primary legal sources and an industry briefing from Cheng Han Biotechnology (正瀚生技). It also identifies unresolved questions concerning product composition, residual cells and DNA, efficacy evidence, and applicable contained-use requirements. These gaps are treated as development tasks, not as evidence of regulatory compliance.
ReLEAF is a three-part system: the bioreactor, the engineered production culture, and the cell-free agricultural output. We examined these components across Taiwan, the European Union, the United States, and potential Southeast Asian markets. The same biological output may be treated differently depending on its composition, intended function, claims, and jurisdiction. We therefore treated regulation as part of product design rather than a final approval step.
Our regulatory analysis follows:
Function → Claim → Classification → Requirement → Market Access
| Principle | Implications for ReLEAF |
|---|---|
| I - Regulation shapes design | Formulation, function, and claims influence the regulatory pathway |
| II - Separate the system | The bioreactor, engineered B. subtilis, and cell-free output raise different regulatory questions |
| III - Claims shape markets | Claiming stress tolerance and no pest control; hence, the fertilizer and biostimulant routes are our main strategy. |
Regulation is therefore not the final checkpoint of ReLEAF – it is one of the constraints that shape what we build, what we claim, and where we sell it.
ReLEAF does not enter the agricultural environment as one undifferentiated product:
| Component | Primary Question | ReLEAF’s Approach |
|---|---|---|
| Bioreactor | Does the equipment meet applicable safety and operating requirements? | Assesses pressure, electrical, fluid-contact, leak-prevention, cleanability, and other applicable equipment requirements |
| Engineered B. subtilis | How is the genetically engineered production organism contained? | Keeps the culture inside the production system, and separately assesses transport, storage and waste rules for genetically modified organisms and micro-organisms (GMOs and GMMs). |
| Cell-Free Output | How should the agricultural product be classified? | Evaluates its composition, function, claims, efficacy, and applicable fertilizer/biostimulant pathway. |
The hollow-fiber membrane (0.2 µm) retains the production culture and lets the soluble products through. Under Regulation (EU) 2019/1009, PFC 6(B) is the category for non-microbial plant biostimulants, and PFC 6 covers functions including improving plant tolerance to abiotic stress. However, our review has not identified a general numerical residual-DNA limit in the Regulation that can be stated as a PFC 6(B) requirement. ReLEAF should therefore not claim a legal DNA threshold unless a specific provision, applicable delegated act, harmonised standard, conformity-assessment requirement, or competent authority interpretation is identified. Independently of the legal threshold, ReLEAF will validate its cell-free output by testing for viable production organisms and residual recombinant DNA, report the methods and detection limits, and describe the hollow-fiber membrane as “designed to retain cells” until retention has been experimentally validated. Containment is not only an engineering requirement; it determines the exposure pathway that regulators must consider. Separating the engineered production organism from the cell-free output lets regulators assess the two as distinct questions.
Ask not “What molecule is this?” but “What is the product intended to do?”
We call these three molecules biostimulants because of what they do in the plant. No authority has classified them, so the column below gives the category we are aiming at. Their intended functions are used to investigate whether a plant-biostimulant pathway could be appropriate for the final cell-free product. Because regulatory classification depends on the final formulation, claims, evidence, and jurisdiction, “Plant Biostimulant (PB)” below represents ReLEAF's current commercialization positioning rather than an approved legal classification.
| Biostimulant | Intended application | Current commercialization positioning |
|---|---|---|
| BoPEP4 | Salinity stress | Plant Biostimulant (PB) |
| AtLEA14 | Drought stress Salinity stress Osmotic stress | Plant Biostimulant (PB) |
| ACCD | Heat stress | Plant Biostimulant (PB) |
Our intended function is therefore abiotic-stress resilience rather than control of pathogens, insects, or weeds. The three biostimulants address complementary stress conditions: BoPEP4 is being investigated for salinity tolerance, AtLEA14 for drought and broader osmotic/abiotic-stress protection, and ACCD for heat-stress mitigation through reduction of stress-induced ethylene. These positions represent ReLEAF's current commercialization strategy, not a final legal classification by any regulatory authority.
Regulation (EU) 2019/1009 defines Product Function Category (PFC) 6 plant biostimulants around improving characteristics including tolerance to abiotic stress. PFC 6(B) covers non-microbial plant biostimulants. This makes PFC 6(B) a potential pathway for ReLEAF's cell-free output, but not an automatic classification. The three molecules are being investigated for the abiotic-stress functions in Table 3. The final product must also satisfy applicable composition, safety, efficacy, labeling, and conformity requirements.
Taiwan
Taiwan is where we build and test ReLEAF. Our lab work, plant trials and farmer meetings are all here, and it is where we would register first. The main regulatory question for the cell-free output is whether its composition, function, and claims fit an existing fertilizer-related category.
Taiwan's fertilizer specifications recognize 植物生長輔助劑類 (Plant Growth Auxiliary Materials) among its fertilizer categories. However, this does not establish that ReLEAF's protein- or peptide-based formulation automatically belongs in that category. Taiwan's Ministry of Agriculture oversees both routes. The Agriculture and Food Agency registers fertilizers under the Fertilizer Management Act, and the Animal and Plant Health Inspection Agency handles pesticides under the Pesticide Management Act. We would confirm our formulation and claims with the Agriculture and Food Agency.
If registered as a fertilizer, ReLEAF would need a defined and reproducible composition, safety and quality data, efficacy data, labeling and registration information.
Because some plant-physiological claims can fall within pesticide-related regulation, ReLEAF will avoid claims concerning the control of pathogens, insects, or weeds. Our intended positioning remains focused on abiotic-stress resilience, with BoPEP4 targeting salinity tolerance, AtLEA14 addressing drought and osmotic stress, and ACCD extending the system to heat-stress mitigation. This does not guarantee fertilizer or biostimulant classification. Final classification remains the responsibility of the competent authority.
The engineered B. subtilis is assessed separately from the cell-free output. Our current review did not identify a general Taiwan contained-use GMO framework that clearly resolves this specific engineered bacterial production scenario.
We therefore treat the applicable pathway as unresolved. Before commercial deployment, we would seek clarification from the relevant authority concerning manufacture, contained use, storage, transport, and waste handling. We will not describe the system as certified for contained use until the applicable framework and evidence requirements have been confirmed.
The bioreactor is an equipment rather than the agricultural product itself. Its requirements depend on the final hardware configuration, including electrical systems, pumps, pressure-bearing components, sensors, and fluid-contact materials. The final commercial design would therefore require a separate equipment-safety and conformity assessment.
European Union
The EU provides a clear framework to investigate ReLEAF's intended function. Under Regulation (EU) 2019/1009, PFC 6 covers plant biostimulants, including non-microbial PFC 6(B). The regulation explicitly includes improvement of tolerance to abiotic stress within the plant-biostimulant function.
PFC 6(B) → CMC Eligibility → Efficacy & Safety → Conformity Assessment → Market Access
Product Function Category (PFC) classification answers what the product does. Component Material Categories (CMCs), on the other hand, answer what materials the EU fertilizing product may contain. An EU fertilizing product must consist only of materials meeting an applicable CMC. This creates two separate questions for ReLEAF:
| Question | ReLEAF Consideration |
|---|---|
| What does the product do? | Improve tolerance to abiotic stress → potential PFC 6(B) |
| What is the product made from? | Cell-free proteins/peptides → CMC eligibility must be established |
| Does it work? | Claims must be supported by efficacy evidence |
| Is it safe and consistent? | Composition, contaminants, stability, and quality require assessment |
| Can it enter the EU market? | Applicable conformity assessment must be completed |
The EU framework therefore creates a direct feedback loop between our wetlab work and regulatory strategy. The intended claim determines the evidence we need to generate: salinity-tolerance evidence for BoPEP4, drought or osmotic-stress protection evidence for AtLEA14, and heat-stress mitigation evidence for ACCD. These experimental results would support the biological rationale for the corresponding claims, but would not by themselves determine the final regulatory classification.
The bioreactor and engineered production culture remain separate from the cell-free fertilizing product. Their applicable equipment and contained-biotechnology requirements must be assessed according to the final design and production system.
United States
The United States differs from the EU because agricultural-input requirements can involve both federal and state authorities. For ReLEAF, the main questions remain:
ReLEAF therefore cannot transfer an EU classification directly to the United States.
Our intended positioning remains abiotic-stress resilience rather than pest control. Depending on the final formulation, claims, and target state, the product may require assessment under fertilizer, beneficial-substance, plant-regulator, or other applicable frameworks.
For the contained engineered microorganism, the Environmental Protection Agency (EPA)’s Toxic Substances Control Act (TSCA) biotechnology framework under ‘Title 40 of the Code of Federal Regulations Part 725’ (40 C.F.R. Part 725) is a principal federal framework to investigate. Whether the final ReLEAF strain qualifies for an exemption or requires notification/review must be determined from the final strain and containment conditions.
The bioreactor requires a separate equipment-safety assessment based on its final electrical, mechanical, pressure, and installation characteristics.
| European Union | United States | |
|---|---|---|
| Main Regulatory Structure | Harmonized EU fertilizing-products framework | Federal agencies + state requirements |
| Plant Biostimulants | PFC 6 under Regulation (EU) 2019/1009 | No single harmonized federal biostimulant pathway |
| Product Claims | Important for PFC classification | Important for determining regulatory jurisdiction |
| Fertilizer Requirements | EU-wide harmonized framework for CE-marked products | Primarily state-specific |
| Engineered Microorganisms | Separate assessments from final product | Product- and use-specific federal jurisdiction |
| Market Strategy | EU-level harmonized pathway | Select target states individually |
After Taiwan and the Philippines, ReLEAF would investigate selected Southeast Asian markets rather than entering the region simultaneously. Here, ReLEAF explores its possible market expansion lineups through categories such as but not limited to: bioreactor, B. sub culture, output laws; farmland mass; smallholder structure; entry ease; technology acceptance; and on-site deployment fitness. Below, Table 6 shows how we ranked them, Table 7 offers the scoring guidelines, and Tables 8 through 13 are the subtables that expands on the Y’s and N’s (Yeses and Noes) of each category used to weigh the markets and what subcategories are entailed within one category. Additionally, each country’s rationale in the market lineup is explained after Table 13.
The United States ranks first in the weighted screening score (32), but its entry-ease score is only 1/5 because of distance and the practical burden of establishing a route across federal and state systems. We therefore prioritize the Philippines as the first international expansion market, followed by Thailand, while treating the United States as a high-value but resource-intensive target. Vietnam and Indonesia remain later-stage candidates under the current scoring model; the EU is a later-stage target for the cell-free output because the engineered production culture raises a separate regulatory barrier.

Our intended sequence, based on the chart, is therefore:

The United States of America, the largest base by far of 356 Mha of farmland, an average farm of 187 ha, and GM crops on 71.5 Mha (about 20% of farmland), so both market size and technology acceptance has a score of 5.
Regulatory-wise, the Environmental Protection Agency’s Toxic Substance Control Act biotechnology process names engineered microbes: a Microbial Commercial Activity Notice of 90 days before commercialization and a field-test application of 60 days before trials, with exemptions for some recipient organisms. Biostimulant categories exist at state level (AAPFCO definition; California permits plant biostimulant label claims from 1 January 2025).
As to why it is not our initial market, the United States has an entry ease score of 1 (about 12000 km from Taipei with no home presence). Additionally, two overlapping regimes (EPA and state) add cost, and there are no federal biostimulant definition (the Plant Biostimulant Act of 2025 is pending), plus a risk the ACCD activity is treated as a plant growth regulator under Federal Insecticide Fungicide Rodenticide Act (FIFRA).
The Philippines is the only Asian market where engineered organisms are named inside the fertilizer system (Fertilizer [and] Pesticide Authority; FPA Memorandum Circular 2018-20). It passes 4 of the 5 culture checks with 3 of 3 evidence checks for the permeate, including a provisional registration after one season of efficacy data collection.
One of its weaknesses is that the amount of farmland in the Philippines are only 12.7 Mha and the average farm size fell to 0.79 ha in 2022 (88% of farms were under 3 ha in 2012), so both market-potential scores (smallholder and farmland) are low. Entry ease is 4 (1160 km away, but a licensed local importer and an FPA-accredited researcher are needed). On the other hand, its technology-acceptance score is a four because GM maize covers about 0.9 Mha, roughly 7% of the farmland.
18~23 pts
The Kingdom of Thailand, a long-established fertilizer regime run by the Department of Agriculture, dictates that biological fertilizers are already recognized as a category. It has the best data-supported third market in Southeast Asia by far with 22.4 Mha of farmland and the largest average farm of the Southeast Asian region (3.2 ha, 2003 census), which gives it the top deployment-fit score.
Documenting registration takes about 8 to 12 months of process; additionally, biofertilizer is a defined fertilizer type. However, Thailand falls short because no commercial GM crop cultivation has been approved (technology acceptance of 1), a draft GMO regulation in 2019, and entry ease is 2 (about 2500 km, no dossier reuse established).
Taiwan, GEMS-Taiwan’s country-of-origin, has arguably the highest entry ease (5/5), largely because it is closest to the team, existing domestic infrastructure, and the easiest place to validate the product and consult regulators. It scores below the Philippines on regulation instead of practicality. On the contrary, its score is held down by market data: 0.56 Mha of farmland for over 80% of farm households cultivating under 1 ha, and no commercial GM crops.
The Fertilizer Management Act requires a registration certificate before any fertilizer is manufactured, imported, or sold. Microbial fertilizers need crop-toxicity, bio-toxicity, and ecological test reports. In 2011, the Ministry of Agriculture published a list of 16 pre-recognized safe strains (8 bacteria, 4 fungi, 4 yeasts), which mostly occur in Taiwan.
An engineered WB800 strain is unlikely to qualify for the simplified list, so it would need the full dossier. However, the Act states it does not apply to organic fertilizer that farmers make for their own use without selling. The on-site model may fit that carve-out, but whether it covers an engineered, purchased culture needs a regulator ruling. Note also that the Act bars repackaging, mixing, or diluting registered fertilizer for sale.
Lastly, domestic market potential is limited by farm size and area (2/5), so Taiwan works best as a validation and reference market for the dossier.
The European Union, the unified union of 27 member states in the region of Europe, holds 156.4 Mha of agricultural farmland with an average farm size of 17 ha and a clear non-microbial biostimulant category score well for the permeate. The culture laws hit a knockout. Regulation (EU) 2019/1009, applied since July 16th, 2022, limits microbial biostimulants to four groups (Azotobacter, Azospirillum, Rhizobium, and mycorrhizal fungi). B. subtilis is not on the list, so the culture fails outside the harmonized route and national rules apply; an EU study to expand the list is under way but not complete.
Additionally, GMO contained-use and deliberate-release rules would likely apply to the engineered strain and are why the culture scores 1/5. There are no central EU registries, products are CE-marked after conformity assessment. However, the cell-free permeate could go through the non-microbial biostimulant route, so the EU stays a long-term target for the permeate, with an EU dossier that could support entry elsewhere.

Socialist Republic of Vietnam has an average farm size of 0.4 ha with 89% of smallholders and 12.3 Mha of farmland, so both market-potential scores (farmland and smallholder) scores are 1.
Decree 84/2019/ND-CP (amended by Decree 130/2022; consolidated in 04/VBHN-BNNPTNT, 2023) requires a Decision on Recognition of Fertilizer for Trade before a product is sold. The application needs a test report from a recognized testing organization; imports need an import permit and a certificate of free sale from the exporting country. Foreign firms must apply through a representative office or branch. However, the Decree sets quality indices for conventional fertilizer classes, so a cell-free biostimulant needs a classification decision, and the GMM status of the production host is a separate question. For example, GM maize is grown on about 0.1 Mha (technology acceptance of 3) and 1800 km distance is short.
The Republic of Indonesia has farmlands spanning 55.1 Mha in area in total (largest in Southeast Asia), but 60.8% of land-using farm households work under 0.5 ha (2023 census) and GM crop areas are under 0.1 Mha. Regulatory-wise, the Ministry of Agriculture Regulation 1/2019 covers organic fertilizer, biofertilizer, and soil amendments, all fileable through the Online Single Submission (OSS), with extra documents for foreign products and a local legal entity needed. Additionally, no engineered-microbe or biostimulant provision was found.
Malaysia has 8.6 Mha of farmland, mainly plantations; no average farm size or smallholder figure was found, so that score was flagged provisional 3.
Regulatory-wise, the Biosafety Act 2007 (act 678) requires the National Biosafety Board (NBB) approval for the release or import of living modified organisms and their products; contained use needs only institutional biosafety committee oversight. Hence, this makes a sealed-cartridge, contained design attractive–no fertilizer-registration source was reviewed, so the permeate score reflects an evidence gap.
Kelpak provides a useful case study for understanding why ReLEAF cannot assume that one regulatory classification will apply globally. Kelpak is a seaweed-derived agricultural biostimulant whose regulatory treatment differs across markets, even though the underlying product remains substantially the same. This makes it particularly relevant to ReLEAF, where the same cell-free protectant output may encounter different legal definitions, registration requirements, and evidence standards depending on the destination market.
| Market | Regulatory Treatment of Kelpak | What This Demonstrates |
|---|---|---|
| European Union | CE-marked EU fertilizing product | Harmonized plant-biostimulant framework |
| Taiwan | Registered fertilizer product | National fertilizer classification |
| United States | Agricultural input with organic-input approval; requirements can also depend on state | Decentralized regulatory system |
The table shows the pattern: Kelpak does not change when it crosses a border, but its pathway does. We therefore treat each target market as a separate regulatory assessment. In the European Union, Kelpak is positioned within the EU fertilising-products framework, demonstrating how a harmonized regional system can provide a defined pathway for plant-biostimulant products. In Taiwan, its registration as a fertilizer illustrates how the same type of agricultural input can instead be evaluated through a national fertilizer classification system. In the United States, Kelpak's market position demonstrates the more decentralized nature of agricultural-input regulation, where federal considerations, organic-input requirements, and individual state requirements can all affect market access.
The contrast is important for ReLEAF because regulatory classification depends not only on the biological material itself, but also on its formulation, intended function, claims, and jurisdiction. Kelpak therefore serves as the main regulatory case study for our project: the product does not change simply because it crosses a border, but the regulatory pathway governing that product can change substantially. ReLEAF consequently treats each target market as a separate regulatory assessment rather than assuming that approval or classification in one jurisdiction automatically transfers to another.
Sagarika is a useful example of a seaweed-derived plant biostimulant, rather than a confirmed microbial biostimulant. IFFCO describes Sagarika Liquid as a concentrated extract of red and brown marine algae (28% w/w), containing naturally occurring plant-growth substances and nutrients. Its official product information therefore supports describing it as a seaweed-extract product; the sources reviewed do not establish that the marketed product is itself a microbial inoculant. Sagarika is relevant to ReLEAF as a comparison for how an agricultural biostimulant is formulated, positioned, and regulated, but it is not a direct biological analogue for ReLEAF's engineered production culture or purified/cell-free protein output. India's regulatory framework for biostimulants was amended through Notification S.O. 882(E) of 23 February 2021, which added biostimulants to the Fertiliser Control Order, 1985, including Clause 20C and Schedule VI.
For ReLEAF, this reinforces the importance of establishing product identity, composition, efficacy, safety, traceability, and containment early.
Our exchange with Cheng Han Biotechnology supplemented our legal research with industry experience from Taiwan, the EU, and the US. This discussion reinforced three practical considerations:
We used this discussion as an industrial perspective rather than as a substitute for official regulatory requirements.
| Component / Positioning | Potential Regulatory Pathway | Why It Could Apply To ReLEAF | Current ReLEAF Position |
|---|---|---|---|
| Cell-free biostimulant output | Fertilizer/Plant Biostimulant | The intended function is to improve tolerance to abiotic stress rather than control pests or pathogens. BoPep4, AtLEA14, and ACCD are being developed to address complementary abiotic stresses. In the EU, PFC 6 includes abiotic-stress tolerance as a plant-biostimulant function. | Primary pathway under investigation. Exact composition, CMC eligibility, efficacy, and conformity requirements remain to be confirmed. |
| Engineered Bacillus subtilis culture | Contained-Use / Biotechnology Framework | The engineered microorganism is the production chassis rather than the agricultural product. Its regulatory status must be assessed separately, including manufacture, transport, storage, containment, and waste. | Separate regulatory question. ReLEAF does not intend to apply the engineered culture directly to crops. |
| Bioreactor | Equipment, Machinery, Electrical, and Potentially Pressure-Related Requirements | The bioreactor contains pumps, sensors, fluid-handling components, electrical equipment, and a hollow-fiber membrane system. | Separate equipment pathway. Requirements depend on the final commercial hardware and target jurisdiction. |
| Direct Application of Engineered Bacteria to Crops | GMO / Environmental-Release and Agricultural Input Regulation | Direct application would create substantially different questions concerning environmental exposure and release of the engineered microorganism. | Not the ReLEAF model. The engineered culture remains contained while the agricultural output is cell-free. |
| Organic-Agriculture Positioning | Organic Input Requirements | Taiwan's Organic Agriculture Promotion Act excludes any product of a genetically modified organism from certified organic production, whatever the containment. Certified organic farming is therefore closed to ReLEAF, about 3.7% of cultivated land. | Not an initial positioning target. ReLEAF's commercial model retains the engineered production organism within the bioreactor. |
The three components therefore form one manufacturing system but do not necessarily share one regulatory identity.
| Issue | Current Status |
|---|---|
| Taiwan - cell-free output | Exact fertilizer category still requires authority confirmation |
| Taiwan - engineered culture | Applicable contained-use framework remains unconfirmed |
| EU - PFC 6(B) | Potential pathway; not an automatic classification |
| EU - CMC | Eligibility of each ReLEAF protein/peptide remains to be established |
| US - engineered culture | Final TSCA Part 725 pathway remains to be determined |
| US - cell-free output | Target-state requirements remain open |
| Efficacy | Commercial claims require ReLEAF's own supporting data: salinity tolerance for BoPEP4, drought/salinity/osmotic-stress protection for AtLEA14, and heat-stress mitigation through ACCD |
| Bioreactor | Final equipment/conformity pathways depend on commercial design. |
ReLEAF’s regulatory strategy can therefore be reduced to five questions:
Regulation has therefore become part of ReLEAF's development process. Our goal is not simply to identify a legal category after the product is built, but to develop the production system, containment strategy, scientific evidence, product claims, and market pathway together.
