Sourcing Single-Botanical Powders Direct: EU and Japan Spec Guide
Buyer’s snapshot
- In the EU, whole-leaf Centella asiatica is catalogued as not novel, while a standardised 40 percent triterpene extract is treated as an unauthorised novel food (European Commission Novel Food status catalogue, updated January 2026).
- In Japan, Centella whole plant sits on the non-medicinal list, while Cassia auriculata bark sits on the medicines-only list (Ministry of Health, Labour and Welfare notification, 2020).
- Regulation (EU) 2023/915 caps lead in food supplements at 3.0 mg/kg and cadmium at 1.0 mg/kg, and those ceilings bind the finished product, not the raw material.
- Silk Foods Ceylon (SFC) runs a first-order minimum of 50 kg per SKU, with volume breaks at 500, 1,000 and 2,500 kg per SKU.
- The copy-ready RFQ block at the end of this guide is written for procurement teams buying leaf and flower powders into the EU and Japan.
Most buying guides for Ceylon botanicals answer the question a formulator asks: what does this ingredient do, and what does the evidence support. That question is already covered for Centella asiatica in the full Gotukola powder spec and evidence guide, and this article deliberately does not repeat it. The wider category view sits in the sourcing guide to Ceylon herbs and Ayurvedic botanicals.
This guide answers the procurement question instead. When a wellness brand in Rotterdam or an ingredient trader in Osaka buys a single-botanical powder direct from the manufacturer rather than through a consolidator, four things move onto the buyer’s desk that a broker previously absorbed: species and plant-part documentation, contaminant compliance against the destination market’s own ceilings, particle-size and moisture control at the mill, and the MOQ and lead-time arithmetic of a direct order. Get those four right and the direct route is cheaper and more traceable. Get the first one wrong and the shipment can be legally unsellable on arrival.
Why the plant part decides the deal before the spec does
A single-botanical powder is defined by three fields, not one: the accepted botanical name, the plant part, and the process applied to it. Buyers routinely specify the first and the third while leaving the second implicit. In the EU and Japan, that omission is the single most expensive mistake available on a botanical RFQ, because both regimes classify by plant part, not by species.
Centella asiatica shows the cleanest example. The European Medicines Agency adopted a European Union herbal monograph for Centella asiatica herba in September 2022 on the basis of traditional use, and that monograph covers the cutaneous route for skin disorders and minor wounds. It does not authorise oral claims. A buyer who cites the monograph to a Dutch or German authority as support for an oral supplement claim has cited a document that argues against them.
The Silk Route Ventures (SRV) trade desk sees the same gap on inbound RFQs with some regularity: the enquiry names the botanical in Latin, names the mesh, names the certification required, and never names the plant part. On a leaf powder that ships to a market with a plant-part-indexed rulebook, that single blank field is what turns a clean order into a customs hold.
The EU gate: leaf powder clears where the extract does not
The EU Novel Food status catalogue, updated in January 2026 and reported by NutraIngredients that month, lists the stem, flower and leaf of Centella asiatica as not novel, while an extract standardised to 40 percent triterpenes is classified as an unauthorised novel food requiring pre-market authorisation. That inverts the usual assumption that a concentrated extract is the more commercially valuable form. For an EU launch, the whole-leaf powder is the form with the shorter regulatory path.
Two qualifications belong in any buyer’s file. First, the Commission states plainly that the catalogue is a non-binding tool, and that the burden of demonstrating significant consumption before 15 May 1997 rests with the food business operator. The catalogue is a strong indicator, not a licence. Second, function health claims on botanicals remain unresolved. The EU Register of nutrition and health claims still carries entries flagged as referring to botanical substances and under further consideration by the Commission and EU countries, a status that has now persisted for well over a decade. Brands should build the label around composition and traditional-use framing rather than around a function claim that is still in the queue.
The Japan gate: two lists, and one of them is a wall
Japan operates a food and medicine division, the shokuyaku kubun, published by the Ministry of Health, Labour and Welfare. Ingredients judged to be used exclusively as pharmaceuticals appear in one annex. Ingredients not judged to be pharmaceuticals, provided no medicinal efficacy is claimed, appear in the other.
Under the March 2020 notification, Centella asiatica (tsubokusa) appears in the non-medicinal annex with the plant part recorded as whole plant. Cassia auriculata appears in the medicines-only annex with the plant part recorded as bark. Ranawara powder for the Sri Lankan tea trade is normally milled from the flower, which is not the listed part, and unlisted parts are decided case by case by the prefectural authority rather than cleared automatically. The correct position for a buyer is therefore precise: Cassia auriculata bark cannot be sold into Japan as a food ingredient, flower material is not on the medicines-only list, and the plant part must be confirmed with the prefectural pharmaceutical affairs office before a purchase order is raised. Any supplier who answers “ranawara is approved in Japan” without that distinction has not read the notification. The notification has also been amended at least twice since 2020, so the consolidated list is the version that counts.
Separately, every commercial import of food into Japan requires an import notification filed with a quarantine station under Article 27 of the Food Sanitation Act before customs clearance concludes.
| Checkpoint | European Union | Japan |
|---|---|---|
| Classification basis | Novel food status by species and plant part | Food and medicine division by species and plant part |
| Centella asiatica | Stem, flower, leaf catalogued as not novel | Whole plant on the non-medicinal list |
| Cassia auriculata | No novel food bar identified for flower material | Bark on the medicines-only list; flower not listed |
| Standardised extracts | 40 percent triterpene Centella extract unauthorised | Assessed separately from the plant material |
| Import filing | Standard import controls and organic transaction certificate where applicable | Import notification to a quarantine station under Article 27 |
| Default pesticide position | Raw commodity MRL applies where no processing factor exists | Uniform limit of 0.01 ppm where no MRL is set |
What the COA has to carry, and what it usually does not
Regulation (EU) 2023/915 sets a maximum of 3.0 mg/kg for lead and 1.0 mg/kg for cadmium in food supplements. The practical trap is that those ceilings apply to the finished supplement, not to each raw material inside it. A leaf powder testing at 2.5 mg/kg lead is a legal raw material and can still push a multi-botanical capsule over the line once the other inputs are added. Buyers formulating blends should set an internal raw-material ceiling well below the statutory number rather than accepting compliance at the ingredient level as sufficient.
The same regulation sets lead limits by spice category rather than by a single dried-herb figure: 2.0 mg/kg for bark spices, 1.50 for root and rhizome, 1.0 for bud and for flower-pistil, 0.90 for seed and 0.60 for fruit. There is no general dried-herbs row, which is precisely why the plant-part field on the specification determines which number the consignment is measured against.
Pesticides work against the buyer by default. Article 20 of Regulation (EC) No 396/2005 allows the concentration effect of drying to be taken into account, but where no processing factor has been established, the MRL for the raw agricultural commodity applies to the dried product. European Spice Association dehydration factors for dried herbs and spices run from about 3 to 13 depending on material, so a powder is being judged against a limit set for the fresh crop it was concentrated from. CBI, the market intelligence service of the Netherlands Enterprise Agency, reported that the leading causes of EU border rejection for herbs and spices in 2025 were chlorpyrifos at 35 cases, multi-residue combinations at 33, and ethylene oxide at 16. Japan is stricter still on unlisted actives: under the positive list system in force since May 2006, a chemical with no established MRL for that food is capped at a uniform 0.01 ppm.
On microbiology, EU legislation sets no numeric limits specific to herbs and spices. Salmonella absence is the mandatory criterion, and every total plate count, yeast and mould, and E. coli figure in a botanical specification comes from the buyer’s own document. If the buyer does not write those numbers, nobody does. CBI confirms this position, and the FAO and WHO joint expert meeting report on microbiological hazards in spices and dried aromatic herbs, published in 2022, identifies Salmonella, Bacillus cereus and Clostridium perfringens as the recognised pathogens of concern in this category.
SFC issues a certificate of analysis on every batch, covering moisture, microbial load, heavy metals, pesticide residues where relevant, and organoleptic parameters where specified, with third-party testing run against customer-specific parameters on request.
Particle size, moisture and the questions buyers skip
Mesh is where botanical specifications become vague. “Fine powder” is not a specification. A capsule filler, a stick-pack blender and a beverage premix each need a different distribution, and the milling route that hits one will fail another. The same discipline applies to multi-herb blends, where particle size governs whether an adaptogen blend stays homogeneous through filling.
Four fields belong on every powder line:
- Target mesh with a stated tolerance, plus whether the requirement is a sieve pass percentage or a full distribution.
- Moisture at dispatch, since a hygroscopic leaf powder will move during a four-week sea transit and arrive outside a tight window that was met at the mill.
- Colour reference, agreed against a retained sample rather than described in words, because leaf powders drift green to olive with drying temperature.
- Sieving and metal-detection steps, stated as process requirements rather than assumed.
The herb line at the Matale facility, which sits at Hapugasyaya in Nalanda about 1 km from the Nalanda Gedige, runs drying, grinding and sieving of herbal material at 100 to 200 kg per hour, or roughly 1 to 2 MT per day, across a 10,000 sq ft processing floor laid out in cellular manufacturing cells. The cellular layout matters commercially rather than technically: adding a new botanical SKU does not require re-auditing the whole plant.
The direct-buy arithmetic
Buying direct changes the numbers a procurement team plans against. SFC sets a first-order minimum of 50 kg per SKU, and that figure is per product, not distributable across a basket. A buyer opening with six botanicals is committing to 300 kg in total, not 50. Volume breaks then sit at 500, 1,000 and 2,500 kg per SKU. Buyers weighing that opening commitment against a consolidator’s smaller drop should read the case for when low-MOQ sourcing is worth it and when it is not before deciding.
| Stage | Timeline |
|---|---|
| Sample dispatch, courier door to door | 3 to 5 business days transit |
| Purchase order to dispatch, production | 2 to 3 weeks |
| Air freight transit | 3 to 4 days |
| Sea freight transit to the EU | 3 to 4 weeks |
Bulk material ships in 25 kg and 50 kg sacks with an LDPE clear gusseted inner bag. Retail-facing kraft pouch formats run from 50 g to 1 kg where the buyer is taking finished packs rather than bulk. The export document pack covers commercial invoice, packing list, bill of lading or air waybill, certificate of origin, phytosanitary certificate, organic transaction certificate where the SKU is organic, and the batch certificate of analysis, with fumigation declarations, per-SKU halal and kosher certificates, shelf-life statements and allergen declarations available on request.
Payment runs 100 percent in advance by bank transfer for orders under $10,000, and 50 percent advance with the balance against scanned shipping documents at $10,000 and above.
Why direct sourcing changes the contaminant conversation
The case for buying direct is usually argued on margin. The stronger argument is documentary. An analysis of 23 years of EU rapid alert notifications published in the Journal of Food Safety in 2024 found 3,741 notifications concerning herbs and spices between 2000 and 2022, about 5.3 percent of the 70,630 notifications recorded across all product categories, with Salmonella, aflatoxin, Sudan dyes, ethylene oxide and pyrrolizidine alkaloids among the leading hazards. The origins carrying the largest shares were India at 23.6 percent, Brazil at 8.7 percent, Thailand at 7.2 percent, Türkiye at 5.8 percent and China at 4.6 percent.
Sri Lanka does not appear in that top five. The concentration sits with the highest-volume trading origins, which is what a buyer would expect from a volume-weighted dataset rather than a quality ranking. The useful conclusion for a procurement team is narrower and more actionable: notification risk in this category attaches to material that has passed through consolidation, blending and re-bagging steps that separate the certificate from the crop. A batch certificate of analysis issued by the manufacturer that milled the material, traceable to the farm, is a different evidentiary object from a certificate issued against a lot assembled from several suppliers.
That is the whole argument for the lean route in one line. The manufacturer holds the audit, the batch record and the farm link. Every intermediary between the mill and the buyer weakens that chain without adding anything the specification asks for.
Volume context is worth keeping in proportion. Sri Lanka’s spices and essential oils exports earned US$449.9 million in 2025, down 2.59 percent year on year against total merchandise exports of US$13,579.38 million, according to the Sri Lanka Export Development Board in January 2026. On the demand side, the American Botanical Council reported in HerbalGram issue 144 that US retail sales of herbal dietary supplements reached a record US$13.23 billion in 2024, up 5.4 percent on the prior year. Ingredient demand is growing faster than Ceylon botanical supply is scaling, which is the market condition that makes securing a direct line worth doing now rather than at the next reformulation.
Buyer’s RFQ checklist for single-botanical powders
- Accepted botanical name, plus the synonym the supplier uses locally.
- Plant part, stated explicitly (leaf, flower, whole plant, root, bark).
- Destination markets, named, so classification is checked before pricing.
- Target mesh with tolerance, and whether it is a sieve pass or a distribution.
- Moisture at dispatch and the acceptable range on arrival.
- Heavy metal ceilings, set at your own internal limit rather than the statutory one.
- Pesticide panel, with the destination market named so the default position is priced in.
- Microbiological limits, written out in full, since the regulation will not supply them.
- Certification required at SKU level, and whether dual organic is needed.
- Volume per SKU per year, so the order lands in the right price tier.
A worked example of the same discipline applied to a seed rather than a leaf sits in the fenugreek powder RFQ checklist, and the commercial terms behind a direct line are set out in the ingredient supply playbook for certified bulk. For buyers building a multi-botanical range, the sibling specifications for Guduchi powder and Sarsaparilla powder and tea cut follow the same format.
Frequently asked questions
What is the first-order MOQ for a single-botanical powder from SRV? The first-order minimum is 50 kg per SKU, applied per product rather than across the order. A buyer taking six botanicals commits to 300 kg in total. Volume breaks follow at 500, 1,000 and 2,500 kg per SKU, and production runs 2 to 3 weeks from purchase order to dispatch.
Does SRV supply bulk botanical powders under USDA Organic and EU Organic? Yes. Silk Foods Ceylon manufactures under BRCGS and FSSC 22000 V6, with USDA Organic and EU Organic held at SKU level. Dual organic certification is the clean path for buyers selling into both the United States and the EU, since equivalence is not recognised across all SKUs. Certification scope is confirmed per SKU at quotation, and the buyer’s guide to organic certifications sets out what each scheme actually gates.
Can gotukola powder be sold in the EU without novel food authorisation? The Novel Food status catalogue lists the stem, flower and leaf of Centella asiatica as not novel, while a 40 percent triterpene standardised extract is treated as unauthorised. The catalogue is a non-binding tool and the burden of proving pre-1997 consumption rests with the food business operator.
Can ranawara powder be exported to Japan? Cassia auriculata bark appears on Japan’s medicines-only list under the 2020 notification, so bark material cannot be sold there as a food ingredient. Flower material is not on that list, but unlisted plant parts are assessed case by case by the prefectural authority. Confirm before raising a purchase order.
What documentation ships with a bulk botanical order? Every batch carries a certificate of analysis covering moisture, microbial load, heavy metals and pesticide residues where relevant, with traceability recorded to farm level. The export pack adds the certificate of origin, phytosanitary certificate and organic transaction certificate where applicable.
How Silk Route Ventures can help
Silk Route Ventures supplies bulk single-botanical powders and Ayurvedic herbs from the Silk Foods Ceylon facility in Matale, which manufactures under BRCGS and FSSC 22000 V6, with USDA Organic and EU Organic held at SKU level. The herb line runs drying, grinding and sieving at 100 to 200 kg per hour, issues a certificate of analysis on every batch with traceability to farm, and opens at 50 kg per SKU so a brand can qualify a botanical before committing to a container. In-house R&D and NPD support sits alongside supply for brands developing a formulation rather than buying a finished specification. Request a sample and the certification dossier, naming your destination markets and plant part, and the trade desk will confirm classification before quoting. Contact us
