Before You Score Anyone: Three Disqualifying Red Flags

These are not point deductions. They are reasons to stop.

  1. A CoA with no ratio declaration. A trikatu certificate showing only a piperine figure documents an assay, not a formulation. If the supplier's standard document does not state the 1:1:1 proportion, the proportion is not being controlled.
  2. A price at or below black-pepper-extract parity. Long pepper trades at a multiple of black pepper. A trikatu quotation priced like plain pepper extract is telling you what is actually in the drum — arithmetic, not suspicion.
  3. Refusal to allow third-party pre-shipment testing. There is no legitimate commercial reason to refuse. A supplier confident in their blend treats independent verification as a sales tool.

The parity test, in one line: before reading any quotation, look up current bulk prices for black pepper extract and for dried pippali. A genuine 1:1:1 trikatu cannot be cheaper than the weighted cost of its own components — any offer that beats that arithmetic has already told you the ratio is not 1:1:1.

The Scoring Framework

Weighted to 100 points across five dimensions, with blend integrity carrying the weight that a formulation product demands. Score suppliers before you see their price, so commercial pressure does not colour the technical read.

1. Blend Integrity — 30 points

CriterionPoints
1:1:1 ratio declared as a CoA specification line, batch formulation record auditable8
Per-component identity testing (TLC) on each botanical before blending7
Total gingerols reported per batch (ginger verification)6
Piperlongumine / long-pepper amide detection available on request5
Manufacturing route stated (extract-then-blend vs blend-then-extract) with matching records4

This dimension does not exist for single-botanical extracts, and it is exactly where trikatu suppliers separate. A supplier who can produce per-component records is running a formulation; one who cannot is running a mixer. The analytical reasoning is set out in our ratio-markers guide.

2. Documentation and Analytical Rigour — 25 points

CriterionPoints
Batch-specific CoA (not a generic specification sheet) with methods named per parameter8
Piperine assayed by HPLC, stated on dry basis7
Acid-insoluble ash, residual solvent and aflatoxin lines present5
Carriers and excipients declared by name and percentage5

3. Testing and Compliance Readiness — 20 points

CriterionPoints
Heavy metals by ICP-MS with numeric per-element limits (not "complies")5
Full USP microbiological panel including pathogens4
EU pesticide MRL screening available with a real report4
Non-ETO declaration, with LC-MS/MS testing available4
Testing at a NABL-accredited (or ISO 17025 equivalent) laboratory3

The ETO line deserves its weight: all three trikatu components are dried, spice-derived materials — squarely the EU's recognised ethylene-oxide risk category, where a positive finding means destruction of the consignment. A supplier who has never been asked about ETO has never shipped this material seriously into the EU. See our guide to EU import requirements for botanical extracts.

4. Traceability and Sourcing — 15 points

CriterionPoints
Correct species declared for all three botanicals — P. longum fruit specifically, not related species or stem6
Batch traceable to raw-material lots for each component5
Country and region of origin stated per component2
Organic certification chain intact where organic is claimed2

5. Commercial Terms and Responsiveness — 10 points

CriterionPoints
Incoterms quoted properly (EXW/FOB/CIF/CIP) to your named destination3
Written payment terms on a proforma invoice, not verbal3
Realistic lead times; samples supplied with the same CoA standard as bulk2
Technical questions answered by someone who can discuss the blend chemistry2

That last line is a fast, reliable probe: ask the commercial contact how they verify the long pepper is really in the blend. A supplier with genuine depth answers in markers and records; a trader answers in reassurance.

Interpreting the Score

ScoreReading
85–100Qualified for bulk supply. Proceed to sample and pre-shipment verification.
70–84Workable with conditions. Require the gaps closed in writing before first bulk order.
55–69Trial quantities only, with independent testing — including the gingerol check — on every lot.
Below 55Not a supplier for a formulation product. The blend-integrity burden will fall entirely on you.

First-Order Protocol

Even with a high-scoring supplier, structure the first commercial order defensively:

  1. Nominate an independent laboratory — Eurofins, SGS or Intertek — for pre-shipment sampling, and put both piperine and total gingerols in the scope. The second assay is what verifies the blend.
  2. Compare the independent report line by line against the supplier CoA; a directional pattern of variance matters more than any single gap.
  3. Retain a sealed, dated sample of the shipped lot for the material's shelf life.
  4. Exercise the piperlongumine check once early in the relationship, and randomly thereafter — its deterrent value exceeds its analytical cost.
  5. Re-verify on any change of season, price or manufacturing site. Blend economics drift with the long-pepper market.

SV Botanica supplies ratio-verified bulk trikatu extract from certified manufacturing facilities in India with batch-specific CoAs from NABL-accredited laboratories, and welcomes buyer-nominated third-party pre-shipment testing. The full parameter list is on the trikatu extract product page; the failure modes this checklist defends against are in adulteration and authenticity.
