Choosing a herbal ingredient supplier comes down to evidence: documents, tests, and consistency, not website claims. This guide gives importers a practical checklist for evaluating any supplier in India or elsewhere: what to request, how to verify it, and the red flags that reliably predict problems later.
Start with the documents
A serious exporter can produce, without delay: a Certificate of Analysis for the exact lot on offer, a written product specification, and the standard export set (commercial invoice, packing list, certificate of origin, and a phytosanitary certificate where the destination requires it). Depending on your market you may also need Halal, Organic, or pharmacopeia (BP, USP, EP) documentation. For the full document walk-through, see our COA and documentation guide.
Read the COA properly
A useful COA names the laboratory, the lot number, the test methods, and the result against each specification line: active markers (for example sennosides by HPLC for senna, lawsone for henna), moisture, ash, heavy metals, and microbial limits. Vague COAs with round numbers and no method stated are a warning sign. Re-test your first shipment at an independent lab in your own country; a good supplier expects this.
What certifications mean (and do not mean)
| Certification | What it covers | What it does not cover |
|---|---|---|
| GMP | Facility practices: hygiene, traceability, documented processes | The spec of a specific lot; check the COA |
| APEDA | Registration with India’s agri-export authority | Product quality by itself |
| Halal | Process compliance for halal markets | Composition or potency |
| Organic | Certified organic cultivation and handling for the stated scope | Every product in the catalog; confirm scope per ingredient |
| FSSAI | Indian food-business registration | Destination-market compliance |
Ask for certificate numbers and issuing bodies, and verify them with the issuer where the stakes are high.
Run a real sample test
Request a sample drawn from a current production lot and test it against the agreed specification. Then confirm in writing that the bulk order will ship against the same spec with a fresh COA. Consistency between sample, spec, and shipment is the whole game in botanicals, where crop, season and cut vary.
Red flags
Walk away, or at least slow down, when you see: no per-lot COA (only a generic brochure spec); prices far below the market with no explanation; health or medical claims on ingredient pages; certifications claimed without numbers or issuers; no physical address or facility detail; pressure to pay in full before documentation; and specifications that change between quote and proforma.
How we handle evaluation
A.R.T International supplies against written specifications with a COA on every lot, GMP and APEDA certified, with Halal, Organic and FSSAI documentation available depending on the product. We expect buyers to test samples and verify documents; send your specification to our export desk and we will respond within 24 hours with current specs and documentation.
Frequently asked questions
What documents should a herbal ingredient supplier provide?
At minimum: a Certificate of Analysis (COA) for the specific lot, product specifications, and standard export documents (invoice, packing list, certificate of origin, phytosanitary certificate where required). Depending on your market, also Halal, Organic or pharmacopeia documentation. A supplier who hesitates on any of these is a risk.
How do I verify a COA is genuine?
Check that the COA names the testing laboratory, the lot number, and the test methods (for example HPLC for active markers). You can contact the named lab to confirm the report, and you should re-test your first shipment at an independent laboratory in your own country.
What does GMP certification actually tell me?
GMP certification covers the processing and packaging practices of the facility: hygiene, traceability, and documented procedures. It does not by itself guarantee the spec of a given lot, which is why the per-lot COA matters alongside it.
Should I always test samples before a bulk order?
Yes. Ask for a sample from a current production lot, not a showcase sample, and test it against the written specification you agreed. Confirm the bulk shipment will carry a COA against that same specification.
Specifications vary by crop, season and grade. For current lot specifications, sennosides or lawsone levels, MOQ and pricing to your destination, ask our export desk for a live COA.
