Three Disqualifying Red Flags

  1. Declares 1:1:1 but cannot verify it analytically. As covered in adulteration and authenticity, ratio manipulation passes a tannin assay perfectly. A supplier without verification capability cannot detect it in their own incoming material, let alone prove composition to you.
  2. Cannot identify the three fruits separately before blending. A supplier who buys pre-blended material is one step removed from the only point where species verification is straightforward — and is trusting someone else's composition.
  3. Ambiguous about extract versus churna. These are several-fold different in concentration. A quotation that does not state which, clearly, is a quotation you cannot evaluate.

The one-question filter: "Do you verify the fruit ratio by marker HPLC, and will that verification appear on every batch CoA?" On a single-botanical extract this question makes no sense. On triphala it is the whole assessment — because it distinguishes a supplier who knows what is in the drum from one who is passing on an assurance.

The Scoring Framework

Weighted to 100 points, with composition control carrying 40 — reflecting that on a blend, composition is the product.

1. Ratio Verification and Composition Control — 40 points

CriterionPoints
Fruit ratio verified by marker HPLC and reported on every batch CoA14
Each fruit species identified individually before blending9
All three species declared by binomial on the certificate6
Chebulagic / chebulinic and ellagic acid figures reported6
Will supply three consecutive batch marker profiles on request5

That last row deserves attention. As explained in the standardisation guide, natural marker variation scatters while systematic under-weighting produces a consistent directional bias. Three batches distinguish the two; one cannot.

2. Raw Material Control — 15 points

CriterionPoints
Deseeded fruit pericarp only — declaration on every batch6
Acid-insoluble ash limited at NMT 2% — catches stone and grit4
Collection status declared (cultivated / wild-collected) per fruit3
Fruit origin and harvest period stated2

3. Assay and Product Clarity — 15 points

CriterionPoints
Total tannins by UV with the method named5
Extract versus churna stated unambiguously in quotation and CoA5
Assay on dry, carrier-free basis; carriers declared by name and percentage3
Will measure vitamin C on request rather than implying amla-level content2

The last row is a small but genuine honesty signal. A supplier who volunteers that extract vitamin C is process-dependent, rather than trading on amla's reputation, is telling you how they handle other claims.

4. Compliance and Contaminant Testing — 15 points

CriterionPoints
Heavy metals by ICP-MS with numeric per-element limits4
Aflatoxin testing by HPLC-FLD4
Full USP microbiological panel including pathogens3
EU pesticide MRL screening with a real report2
Non-ETO declaration with LC-MS/MS available2

Aflatoxin earns its weighting on a dried-fruit blend stored in a warm climate before processing — and note that with three fruits, you have three raw-material streams each carrying that risk.

5. Consistency and Commercial Terms — 15 points

CriterionPoints
Three consecutive batch CoAs with consistent ratio verification5
Can quote and verify a custom ratio if required3
Incoterms quoted properly to your named destination3
Written payment terms on a proforma invoice2
Technical questions answered by someone who understands the chemistry2

Interpreting the Score

ScoreReading
85–100Qualified for bulk supply. Proceed to sample and pre-shipment verification.
70–84Workable with conditions. Close the gaps in writing before first bulk order.
55–69Trial quantities only, with independent ratio verification on every lot.
Below 55Not a supplier for a regulated market.

Apply a hard floor on section 1: below 25 of 40, decline regardless of total. A supplier can score full marks on contaminants, terms and responsiveness while being unable to tell you what proportion of each fruit is in the drum. On a blend, that is not a gap in the specification — it is the absence of one.

The Manufacturer-Versus-Trader Question

More consequential on triphala than elsewhere, and worth asking directly.

A manufacturer buys three fruits, identifies each, blends to a controlled ratio and extracts. Composition is under their control and verifiable at the point it is created.

A trader buys finished triphala extract and resells it. Whatever the ratio is, they inherited it — and verifying composition on a finished blend is harder than controlling it during blending.

Ask: "Do you blend from identified fruit, or buy blended extract?" Both can be honest businesses. Only one controls the thing that defines the product.

The Sample Stage

First-Order Protocol

  1. Nominate an independent laboratory — Eurofins, SGS or Intertek. Put ratio markers in the scope — chebulagic/chebulinic and ellagic acid — not just total tannins. An independent tannin figure reproduces exactly the blind spot you are paying to close, and this is the most common error in triphala verification.
  2. Compare the independent marker profile against the supplier's and against the declared ratio.
  3. Retain a sealed, dated sample, stored dry and sealed given the material's hygroscopicity.
  4. Re-verify at batch three, then annually — and always when one of the three fruits has a poor season. Rising cost on any single fruit raises the incentive to re-weight the blend.

SV Botanica identifies each fruit before blending, verifies the ratio by marker HPLC on every batch, reports the chebulagic/chebulinic, ellagic and gallic acid figures, and supplies a deseeded declaration with all three binomials on every certificate. Buyer-nominated third-party pre-shipment testing is welcome. See the product page, the buyer's guide, or adulteration and authenticity.
