Who buys turmeric, and in what quantity

Turmeric is a smaller trade than its cultural prominence suggests. Global imports of Curcuma longa under HS 0910.30 run at around USD 519 million a year, against roughly USD 504 million of recorded exports. For scale, that is a fraction of the sesame or chickpea trade. It is a high-visibility, modest-volume commodity.

On the export side the concentration is extreme. India accounts for about USD 334 million, or 66 percent of world turmeric exports. Myanmar is a distant second at around USD 31.5 million. The Netherlands and Germany appear in the export table as re-exporters, not growers: they buy Indian material, clean and steam it to European microbiological standards, and sell it on within the EU at a margin.

Note the fourth line of the import table. India is itself a significant importer of turmeric, mostly lower-cost Myanmar material destined for colour extraction and oleoresin. That is a useful signal about how the market segments, and it is covered further down.

The problem that organic certification does not solve

We should state this plainly, because it concerns the origin we sell from.

Lead chromate is a bright yellow industrial pigment. It has been documented as an adulterant in the South Asian turmeric supply chain, added to improve the colour of dull or low-grade rhizomes. A 2024 study published in Science of the Total Environment by Forsyth and colleagues tested 356 samples — 180 dried roots and 176 powders — collected from wholesale and retail markets in 23 cities across India, Pakistan, Sri Lanka and Nepal between December 2020 and March 2021. The findings:

• 14 percent of samples, 51 in total, carried lead above 2 micrograms per gram.
• In samples at or above 18 µg/g, the lead-to-chromium molar ratio sat close to 1:1 — the signature of lead chromate rather than environmental contamination.
• Lead exceeded 1,000 µg/g in samples from Patna, Karachi and Peshawar.
• Modelled child blood lead levels in those areas reached up to ten times the US CDC threshold of concern.

Set that against the regulatory limit. Regulation (EU) 2023/915 permits a maximum of 1.50 mg/kg of lead in root and rhizome spices. A sample at 1,000 µg/g is more than six hundred times that figure.

Now the part that matters commercially: an organic certificate does not test for this. NPOP, the USDA National Organic Program and the EU organic regulation are all process standards. They govern what may be applied to a crop and how it must be handled and segregated. They do not set contaminant limits and they do not require heavy metals analysis. A deliberately adulterated lot can be fully compliant with every organic requirement in the chain, because the adulteration happens after the point the organic system is looking at. The USDA organic seal has never been a heavy-metals assurance and was never intended as one.

If you are buying organic turmeric and your file contains an NPOP scope certificate, a transaction certificate and nothing else, you have documented the farming system and left the actual risk untested.

Why the usual quality spec makes it worse

This is the uncomfortable part. Turmeric is widely bought and graded on colour — ASTA colour value, or a bulk absorbance reading on a solvent extract. The brighter and more saturated the yellow, the better the lot scores and the more it is worth.

Lead chromate is a yellow pigment. Adding it improves the number that the trade uses to grade the goods. The specification most buyers rely on is the specification the adulteration is designed to satisfy. A lot can test well on colour, meet its moisture and ash limits, carry a clean organic certificate, and still be the problem.

Two consequences follow for how you write your purchase specification.

Separate the colour test from the curcumin test

A bulk spectrophotometric reading tells you how yellow an extract is. It does not tell you what is making it yellow. HPLC with peak identification separates and quantifies the three curcuminoids individually — curcumin, demethoxycurcumin and bisdemethoxycurcumin — by retention time and spectrum. An inorganic pigment does not produce those peaks. A curcuminoid profile by HPLC is therefore a far harder figure to fake than a colour value, and it is the number to put in your contract.

It also means that a curcumin percentage quoted without a method is not a specification. Ask which method, and ask for the chromatogram, not only the summary figure on the certificate of analysis.

Require a heavy metals report on the shipped lot

Lead, and chromium alongside it. Chromium matters because the lead-to-chromium ratio is diagnostic: environmental lead uptake does not arrive with a stoichiometric chromium partner. Testing both tells you not just whether lead is present but what kind of lead problem you have. A site report from six months ago on a different lot does not answer this. The analysis must be on the consignment.

Curcumin, variety and a disclosure about our own position

Turmeric is not one commodity. The split between material bought for colour and material bought for curcuminoid content is the central fact of the trade, and the varieties serve different ends.

Indian turmeric as a whole runs from roughly 1.5 percent to above 5 percent curcuminoids. Which end of that range you need depends entirely on the application, and paying for 6 percent material to make a curry powder is a waste of money.

Our own disclosure. We are based in Rajkot, Gujarat. Gujarat is not a significant turmeric state. When we quote Lakadong we are sourcing from Meghalaya and when we quote Alleppey we are sourcing from Kerala — in both cases from certified organic groups a long way from our own operation, with a longer internal chain of custody than applies to our groundnut, sesame or cumin, which come from the belt we sit in. That is a reason to interrogate our traceability documents harder on turmeric, not less. We would rather you knew that from us than discovered it in an audit.

Curcumin degrades after you buy it

Curcuminoids are sensitive to light and to prolonged heat. A certificate of analysis records the lot at the moment of testing. Material held in a hot warehouse in clear packaging for six months will not assay the same on arrival. If you are buying to a curcumin minimum, state whether the minimum applies at shipment or at discharge, specify opaque packaging, and agree who bears the cost if it drifts. This is an ordinary commercial term that is very often left out, and it causes more disputes than it should.

The three layers of organic paperwork

Organic turmeric arriving in a regulated market has to satisfy three separate systems. They are not alternatives to one another and a certificate from one does not discharge the others.

Contaminant and regulatory limits worth writing into the contract

Two notes on the border control line. First, the annexes to Regulation (EU) 2019/1793 are revised roughly twice a year, and the January 2026 revision applying from 18 February 2026 made several changes affecting Indian goods: nutmeg was removed for aflatoxins, vanilla and cloves were removed for ethylene oxide, okra was removed for ethylene oxide while remaining listed for pesticide residues, and Piper peppers along with dried, crushed or ground Capsicum and Pimenta moved from Annex II to Annex I for ethylene oxide. A further amendment was adopted on 9 June 2026. Check the position at the date of shipment rather than relying on this table.

Second: turmeric not being listed is good news, but it is not a certificate. It means consignments are not pulled for mandatory increased checks as a category. It does not mean a consignment cannot be sampled, and it does not mean the limits do not apply.

Microbiological reduction without fumigation

Turmeric goes through a wet process. Rhizomes are boiled or steamed, then dried in the open. That combination makes microbiological load a standing issue, and Salmonella is the organism European and American buyers specify against.

Conventional supply chains have historically handled this with fumigation or with ethylene oxide. Organic certification prohibits both, and ethylene oxide is prohibited on food in the EU regardless of organic status. The permitted routes are:

• Validated saturated steam treatment — the mainstream option. It works, but it is heat, and heat is what curcuminoids and volatile oil do not like. A process validated for log reduction without quantifying its effect on the curcumin assay is only half validated.
• Controlled atmosphere or carbon dioxide treatment — effective against insects, slower, and not a substitute for a pathogen kill step.

In India these treatments operate under the National Standards for Phytosanitary Measures, NSPM-25. Ask for the validation report on the specific process and the specific commodity. A generic statement that the lot was “steam sterilised” tells you nothing about log reduction achieved or about what the treatment cost you in curcumin.

Organic is not an analytical zero

This applies to every organic commodity and it is worth repeating here. Organic certification governs what may be applied. It does not promise that nothing will ever be detected.

Pesticide drift from neighbouring conventional fields, carry-over on shared drying yards, shared grinding lines and shared transport all produce low-level detections in genuinely organic material. The question a competent buyer asks on a positive result is not “is this organic?” but “at what concentration, and is that concentration consistent with drift or with application?” Drift sits in parts per billion. A result in parts per million is a traceability question, and it should be investigated as one.

A supplier who tells you their organic turmeric will test at zero for everything is either not testing or not telling you the results.

What to ask before you place the order

1. The NPOP transaction certificate for the specific lot, verified directly with the certifying body.
2. A heavy metals report on the shipped lot covering lead and chromium, from an accredited laboratory.
3. Curcuminoid content by HPLC, with the chromatogram, not a colour value presented as a curcumin figure.
4. The variety and growing region, stated — not “Indian turmeric”.
5. The microbiological treatment used, with the validation report, and the curcumin assay taken after treatment rather than before.
6. Whether the curcumin minimum applies at shipment or at discharge, and the packaging specified to hold it.
7. For the United States: the NOP Import Certificate, raised before the goods move.
8. For the EU: the COI in TRACES NT, with the product description matching the commercial documents.

Frequently asked questions

Does organic certification mean turmeric has been tested for lead?

No. Organic certification under NPOP, the USDA National Organic Program or the EU organic regulation governs what may be applied during cultivation and processing. It is a process standard, not a contaminant testing standard. Lead chromate adulteration is deliberate addition of a pigment after harvest, and no organic certificate tests for it. You need a separate heavy metals report on the shipped lot.

What is a normal curcumin content for Indian turmeric?

Standard commercial Indian turmeric from the Erode, Salem, Rajapuri and Nizamabad growing areas typically runs around 2 to 3 percent curcuminoids. Lakadong turmeric from Meghalaya is the recognised high end at roughly 5 to 7 percent. Any figure is only meaningful if the test method is stated, because HPLC quantification of the three individual curcuminoids and bulk spectrophotometric readings are not interchangeable.

Is turmeric from India subject to increased EU border controls?

Turmeric is not listed for India in the annexes to Regulation (EU) 2019/1793 as they stood at the January 2026 update. Other Indian spices are listed, including peppers of the genus Piper and dried Capsicum and Pimenta for ethylene oxide. Those annexes are revised roughly twice a year, so confirm the position at the date your container is shipped rather than relying on a figure in an article.

What is the EU maximum level for lead in turmeric?

Regulation (EU) 2023/915 sets a maximum level of 1.50 mg/kg for lead in root and rhizome spices, which covers dried turmeric. For comparison, a 2024 study of South Asian markets found samples exceeding 1,000 micrograms per gram, which is more than six hundred times that limit.

How is organic turmeric treated for microbiological reduction if fumigation is banned?

Organic standards prohibit synthetic chemical fumigants and ethylene oxide. The permitted routes are validated saturated steam treatment, controlled atmosphere or carbon dioxide treatment. In India these are carried out under the National Standards for Phytosanitary Measures, NSPM-25. Ask for the validation report for the specific process, not just a statement that the lot was treated.
