Independent sourcing note: We are an independent butterfly pea flower tea B2B sourcing desk — we curate verified Indonesian growers and tea makers and route your RFQ to a vetted partner; we are not the manufacturer, exporter of record, or freight forwarder. Butterfly pea is dried Clitoria ternatea flowers, graded by colour and moisture and also sold as petals, powder, and extract. Figures (MOQ, FOB per kg, lead times) are indicative ranges and vary by grade, season, and volume — final terms are by quote. Compliance (pesticide-residue limits, organic certification, food-contact, and import status such as EU novel-food, which is uncertain) is your responsibility to verify with the supplier and a licensed customs broker — this is general trade information, not legal or regulatory advice. We may earn a sourcing commission on referred orders (referral disclosure).
A butterfly pea sample order playbook is a structured sequence — spec definition, paid sample request, physical evaluation, CoA cross-check, trial order — that a buyer runs before committing any volume of dried Clitoria ternatea to a commercial purchase order. The logic is simple: sample cost is measured in tens of dollars; an FCL that fails on arrival is measured in tens of thousands. What follows is the sequence this desk uses to walk a buyer from initial inquiry to a retained reference sample and, eventually, a production lot that matches it.
A disclosure before we start: this desk routes RFQs to a vetted partner network and may earn a referral fee if you proceed — that is how independent sourcing desks are funded, and it comes at no extra cost to you. No supplier can pay to change what we publish here.
EU buyers, stop here first. Clitoria ternatea as a food or food ingredient is currently not authorized in the European Union. EFSA raised safety objections (EFSA EN-7084), the Commission terminated the authorization procedure (C(2026)776), and RASFF enforcement notifications have been issued against consignments from multiple origins. Sampling for R&D or supplement use may sit in different regulatory territory depending on your member state, but you must take your own legal and regulatory advice before ordering any quantity for EU food use. This is trade information, not regulatory advice.
Step 1 — Define the Spec Before You Request Anything
The first sample butterfly pea steps most buyers skip are the ones that happen before the email to a supplier is drafted. A vague inquiry produces a vague sample — usually a showroom pouch chosen for visual appeal rather than production representativeness. A precise inquiry produces something you can actually evaluate.
Before contacting any supplier or desk, write down the following:
Product form
Whole dried flower, broken petals and fines, or milled powder. These are three different commodities with different handling, different quality signals, and different prices. Whole flowers suit premium loose-leaf tea and cocktail visual presentations; broken petals suit extract feedstock and blending; powder is the colorant and latte-mix workhorse. If you are still deciding, say so — a good desk will help you match form to application before a sample is even sent.
Grade intent
Premium tea grade typically specifies at least 90% intact whole flowers by mass, deep uniform blue color, minimal browning. Standard food-grade has more tolerance for broken petals and minor color variation. Blend and extract grade accepts a lower intact ratio because the material will be processed further anyway. Note that butterfly pea has no formal ISO or Codex grading system — these are industry-norm descriptions. Our grades and quality standards page breaks this hierarchy out in full.
Target moisture and color spec
State your moisture target: ≤10% is the defensible premium target, ≤12% the standard grade target, both inferred from general dried-herb and Codex practice rather than a species-specific published standard (none exists as of mid-2026). Include water activity: ≤0.60 is the general dried-herb norm for inhibiting mold growth. For color, request a spectrophotometric absorbance figure at a defined wavelength in the 560–620 nm range — that gives you a number to compare across batches and against future production lots.
Certification requirements
State these up front: USDA NOP organic, HACCP, ISO 22000, FSSC 22000, or any market-specific certification. A sample drawn from an uncertified line tells you nothing about what an organic-certified production lot will look like. Getting the certification requirement on the table before the sample is sent avoids that mismatch.
Commercial volume intent
Suppliers invest time and overhead in sample preparation. Stating whether you are building toward 100 kg or 5,000 kg is not committing you to anything — it is giving the supplier context to decide whether the relationship is worth the setup cost of a proper sample program. Be honest about this.
Step 2 — Request a Butterfly Pea Paid Sample (Not a Free Pouch)
Free samples exist across the butterfly pea supplier market and they are almost uniformly useless for sourcing decisions. A free courtesy packet is typically hand-selected for visual impact, photographed for catalogs, and sent without any batch documentation. It tells you what the supplier wants you to think the product looks like. That is not the same as what you will receive when 300 kg ships from Tanjung Priok.
When you request a butterfly pea paid sample, the economics change. Supplier charges for sample preparation and courier — typically somewhere in the range of USD 30 to 100 or more, depending on weight, grade, and shipping destination, though sample pricing is by quote and no fixed rate is meaningful to publish. That charge functions as a qualification filter on both sides: it signals the buyer is serious about a commercial relationship, and it gives the supplier a reason to pull from a real production batch and generate real documentation.
What should accompany the paid sample
A properly documented paid sample should arrive with:
- The physical material in a food-grade PE or PP bag, ideally vacuum-compressed, in an outer carton with a batch label showing lot number, production date, and net weight.
- A CoA — Certificate of Analysis — tied to that specific lot, not a generic or historical document. The production date on the CoA must be consistent with the sample’s batch label. Historical CoAs are not useful for evaluating the lot in front of you.
- Supplier food-safety certifications: GMP (BPOM or equivalent), HACCP documentation, ISO 22000 if applicable. Request the certificate number and issuing body name so you can verify independently.
- Traceability information: region of origin, harvest date range for the batch, and the processing facility. A supplier unable to trace a sample batch to its origin cannot investigate a quality problem later.

Step 3 — Evaluate Butterfly Pea Sample on Arrival
When the parcel arrives, run the physical evaluation before you open the CoA. Lab data confirms what you already suspect; your senses catch what the lab did not test for.
Color depth and uniformity
Open the bag and spread a small handful on a white surface under natural light. The blue pigment in butterfly pea — a family of polyacylated delphinidin-3,3′,5′-triglucosides called ternatins — degrades under high heat, prolonged light exposure, and excess moisture during drying. A well-dried lot looks deep, saturated, and consistent across the spread. A lot with visible browning at petal edges, grey fading, or patchwork color has lost ternatin content and will underperform in any color-yield application.
Run a pH shift test: steep a small pinch in ambient-temperature water for two minutes. The infusion should be a clear deep blue at neutral pH. Add a few drops of lemon juice or citric acid solution and watch for a visible shift through purple and into pink-magenta. A weak or muddy response — one that starts grey-blue and barely shifts — indicates degraded anthocyanins. This takes under five minutes and requires no equipment beyond a white cup and something acidic.
Intact-to-broken ratio
For premium tea and cocktail-visual applications, weigh out 10 g and sort manually. Premium grade is typically specified at ≥90% intact whole flowers — at most one in ten flowers showing broken petals, torn calyxes, or fragment-level damage. If you are sourcing for extract or blend use, the ratio matters less; if your end product features the flower visually, every broken piece in a retail pouch is a customer complaint. Count both categories and record the number; it becomes your acceptance criterion for production lots.
Foreign matter
Butterfly pea is harvested by hand from smallholder plots across Java, Bali, and other growing areas in Indonesia. Hand-picking is careful work but it is not sterile. Spread the sample thinly and check for stems, leaf fragments, seed pods, dust, and insect parts. A well-processed premium lot should show minimal foreign matter; a lot with a high proportion of stems and fines mixed in has not been sorted after harvest. That affects your usable yield, not just the aesthetics.
Odor
Open the bag and smell immediately. Good dried butterfly pea flowers have a mild, clean, faintly vegetal note. The checks here are against off-notes:
- Musty or mold-adjacent odor — the most important warning. High moisture creates conditions for mold and mycotoxin development, often invisible in early stages. Industry practice infers moisture at ≤10% for premium and ≤12% for standard grade; off-odor on arrival suggests a lot above those thresholds. Do not proceed to CoA review without sending it to a lab for moisture, water activity, and mycotoxin testing.
- Stale or rancid note — can indicate oxidation from poor packaging or prolonged storage beyond the supplier-stated shelf life of 18–24 months under proper cool, dark, airtight conditions.
- Chemical or solvent odor — raises pesticide or fumigant questions immediately. Flag it and request the pesticide multi-residue panel before any further steps.
Step 4 — Cross-Check the CoA Fields
The CoA is only as useful as the lab that issued it and the batch it was drawn from. A CoA from a supplier’s in-house quality room carries far less weight than one from an ISO/IEC 17025-accredited third-party. If a supplier cannot name the third-party lab, or if the CoA address matches the supplier’s facility, ask for a retested sample at a named independent lab before any commercial commitment.
Work through the CoA in this order:
- Moisture content (%)
- The baseline physical indicator. Target ≤10% for premium grade, ≤12% for standard, both defensible inferences from general dried-herb practice. A CoA showing 13–14% is not an automatic rejection but warrants a conversation about storage and shelf life.
- Water activity (αw)
- More predictive of mold risk than moisture percentage alone. Target ≤0.60 — the general threshold for inhibiting most mold growth in dried botanicals. If the CoA does not include water activity, ask for it. A lot at 9% moisture with αw 0.65 can still support mold growth in humid storage; a lot at 11% moisture with αw 0.58 is meaningfully safer.
- Microbiology panel
- Minimum: Total Plate Count, yeast and mold count, Salmonella absent per 25 g, E. coli absent per 25 g. These last two are non-negotiable for any food import. US FSMA requires importer supplier verification, which at minimum covers the microbiological results. Add mycotoxins — aflatoxins B1, B2, G1, G2 and ochratoxin A — if the odor check raised any concern, or if the supplier cannot confirm controlled-humidity storage with temperature logs.
- Pesticide multi-residue screen
- Run by LC/GC-MS/MS, covering at least 200 compounds. Smallholder-grown butterfly pea across Indonesian growing areas may carry organophosphate, carbamate, or fungicide residues without documentation. US buyers: EPA tolerances and FSMA/FSVP supplier verification apply. EU buyers: Regulation (EC) No 396/2005 MRLs are the world’s most stringent benchmark for herb exports, regardless of the current novel-food non-authorization status.
- Heavy metals by ICP-MS
- Lead (Pb), cadmium (Cd), arsenic (As), mercury (Hg) at minimum. Indonesia’s volcanic soils vary considerably by region in naturally occurring metal content. Specify the limits from your destination market’s regulation in the purchase order; confirm the CoA methodology is ICP-MS and not the less precise XRF screening.
- Anthocyanin color strength
- This is the commercially critical field. Ternatins absorb most strongly in the 560–620 nm range; the CoA should report spectrophotometric absorbance at a defined wavelength and concentration, or total anthocyanin content using the pH differential method (absorbance at 520 nm at pH 1.0 vs. pH 4.5). Either method is acceptable; what matters is that the method is stated and consistent between batches so you can compare a production CoA against this sample CoA. A significant drop in anthocyanin strength between sample and production is a legitimate basis to reject or renegotiate.
See our sample ordering and vendor vetting page for the full CoA field checklist and what to look for in traceability documentation.
Step 5 — Retain the Sample as a Production Reference
Once the sample passes both physical evaluation and CoA review, do not discard it. Retain a defined portion — at least 50 g, ideally 100 g, sealed in an airtight food-grade container, labeled with the lot number, production date, supplier name, and your evaluation date — and store it in a cool, dark, dry environment. This is your production reference.
When production lots ship, request the production-lot CoA from the same third-party lab before authorizing shipment. Compare moisture, water activity, anthocyanin color strength, and the microbiological panel to the sample CoA. If the production CoA shows a material discrepancy in any critical parameter, you have documented evidence of a specification gap and a retained physical reference to compare against. A supplier who holds their own retention samples from each batch — ask specifically whether they do — can confirm from their end as well.
This step costs nothing beyond a labeled jar and a shelf. It is the most underused quality tool in the buyer’s playbook.
Step 6 — Trial Order Before FCL
A good sample does not guarantee the production lot. This is not a polite hedge — it reflects a documented reality in the botanical export trade. Samples are often drawn from carefully prepared batches by quality-conscious staff who know the material is going to a prospect. Production lots are what happens when the system operates at commercial speed under normal conditions, sometimes across multiple drying batches aggregated to fill one order.
The trial order is the bridge that closes this gap.
| Stage | Typical volume | Key purpose | What you get |
|---|---|---|---|
| Paid sample | 100 g – 1 kg | Physical evaluation, CoA baseline, supplier document check | Go/no-go decision; retained reference sample; sample CoA |
| Trial order | 20 kg – 100 kg (indicative; by quote) | Verify production-lot consistency; test customs clearance chain; baseline the relationship | Production-lot CoA from named lab; customs clearance experience; supplier communication record |
| First FCL | ~3–5 MT (20 ft, estimated) or ~6–10 MT (40 ft, estimated) | Commercial volume; FCL freight economics; scale the relationship | Full trade documentation; verified, tested supplier relationship |
A note on FCL volumes: dried butterfly pea flowers are light and bulky. Bulk density is estimated around 100–150 kg per cubic metre based on analogous dried herbs — no butterfly-pea-specific published figure exists. A container cubes out (fills by volume) well before reaching its weight limit, so the estimated 3–5 MT per 20 ft and 6–10 MT per 40 ft are rough planning figures only. Confirm with your freight forwarder based on the specific lot’s packing and vacuum-compression configuration. Main Indonesian export ports for dried herbs are Tanjung Priok (Jakarta), Tanjung Perak (Surabaya), and Tanjung Emas (Semarang); routing is order-specific.
The trial order reveals what the sample cannot: whether the supplier’s quoted lead time of 1–3 weeks ex-stock or 4–8 weeks production-against-order is real; how they communicate during production; whether customs documentation is complete and correct at your destination. Buyers who skip the trial order and go straight from sample to FCL occasionally win on price and cycle time. More often they discover discrepancies they could have caught for the cost of 50 kg.

Frequently Asked Questions
What is the butterfly pea sample price and why is it by quote?
Sample pricing is not published by any desk or supplier that operates a serious sample program, for a straightforward reason: it varies by the weight requested, the grade, the preparation overhead for that specific grade (hand-sorting for premium whole-flower takes more time than scooping fines), and the actual courier cost to your destination country. A published flat rate would be wrong almost immediately. Expect the structure to reflect a small-quantity material premium plus actual shipping — not a catalogue number. Request a quote via the desk and you will get the breakdown you can compare across suppliers, rather than a single number that obscures the components.
How do I evaluate a butterfly pea sample if I do not have a laboratory?
You can run three meaningful checks without any lab equipment: a visual color-uniformity assessment on a white surface under natural light (browning and grey fading are visible); a manual intact-flower sort on a 10 g subsample (count intact vs. broken, both categories matter); and a pH shift test — steep a small pinch in room-temperature water and add a few drops of lemon juice. A properly dried, high-ternatin lot should shift clearly from blue through purple to pink. These three checks will catch most of the common failure modes — color fade from over-hot drying, broken-ratio misrepresentation, and degraded anthocyanins — before you even open the CoA. The lab tests (pesticide screen, heavy metals, micro panel) cannot be run at home; those are handled through an accredited third-party and should be on the CoA the supplier provides with the paid sample.
What are the first sample butterfly pea steps for a buyer who has never ordered before?
Start by writing down the product form (whole flower, broken petals, or powder), the grade you need (premium, standard, or blend grade — our grades page explains the differences), and whether you need any certification (organic, HACCP, ISO 22000). Then contact a vetted desk — or us directly via our enquiry form — with that brief. A good desk will confirm the spec makes sense for your application, route the RFQ to a verified supplier, and make sure the paid sample comes with a proper CoA and batch documentation. Do not accept a free sample as a substitute for this process; it will not tell you what you need to know about production quality.
Can a good sample guarantee the production lot will match?
No, and any desk that implies otherwise is not being honest with you. A sample is drawn from a specific batch, often one prepared carefully because someone knows it is going to a prospective buyer. A production lot aggregated across multiple drying batches and produced at commercial speed may vary in anthocyanin color strength, moisture, and intact-flower ratio. The protection is the retained reference sample plus a production-lot CoA from the same third-party lab, compared before shipment is authorized. That comparison, and a trial order before any FCL commitment, is how a careful buyer closes the gap between sample quality and production reality.
Should EU buyers request a butterfly pea sample for a food product?
Clitoria ternatea as a food or food ingredient is currently not authorized in the EU. EFSA raised safety objections under dossier EN-7084; the Commission terminated the authorization procedure under Decision C(2026)776; RASFF notifications have been issued including against consignments from Cambodia and triggered recalls in Belgium and Austria. Marketing butterfly pea as an EU food ingredient is not a gray area. If you are an EU buyer exploring R&D use, cosmetics, or supplement applications — which may be governed differently depending on the member state — you must take qualified legal and regulatory advice specific to your use case before importing any quantity. This desk cannot advise on EU regulatory compliance. We can route a sourcing inquiry to a vetted partner once your legal position is clear.
