Turmeric Supply Outlook: Harvest Calendar and Arrivals

How does turmeric's annual harvest cycle affect supply?

Turmeric is harvested once a year in a concentrated window rather than continuously, so world supply alternates between old-crop carryover stock and new-crop arrivals within any given trading year.

Unlike some tropical spices that yield two cycles annually, turmeric rhizomes are dug once per season and then processed before they are fit for export. This creates two distinct supply phases that buyers track separately: old crop, meaning material carried over from the prior harvest, and new crop, meaning material processed after the current harvest closes. Old crop is often offered at a discount but can show higher moisture loss, more fiber, and curcumin values at the low end of range. New crop is generally closer to target specification but arrives later in the trading calendar and can carry a premium in the first weeks after release.

The exact harvest window, growing region, and producing country are not published by ODOD LLC. This information is confidential to each contract and is stated only on the quotation and the shipping documents issued for the specific lot booked. What matters for planning purposes is the crop-year designation on the offer, not the geography behind it.

When does new-crop turmeric typically reach US buyers?

New-crop turmeric generally reaches US importers several months after the harvest closes, once primary processing, quality testing, and ocean transit are complete.

After digging, rhizomes go through cleaning, drying, and polishing before they qualify as export-grade material. This processing stage, plus internal quality checks and export documentation, typically adds four to eight weeks before a lot is ready to book. Ocean transit to US ports then adds another 25 to 40 days depending on the shipping lane and whether the order moves as FCL (full container load) or LCL (less than container load, consolidated with other cargo). Buyers who need continuity of supply across the calendar year usually place two to three orders spaced through the year rather than one large order timed to the harvest, since a single order timed poorly can leave a gap between old-crop depletion and new-crop release.

How is turmeric graded for export?

Turmeric is graded primarily on curcumin content, color value, moisture, and form, and these figures must be confirmed on the certificate of analysis for the specific lot rather than assumed from a general table.

Curcumin content is measured by HPLC (high-performance liquid chromatography) and is the main driver of price tier. Color is expressed as an ASTA (American Spice Trade Association) color value, measured by spectrophotometer, and correlates with curcumin and with the visual richness of the powder. Moisture affects shelf life and is capped for export-grade material. Form matters too: whole finger (the elongated primary rhizome), whole bulb or round (the rounder secondary rhizome), and ground powder each serve different buyers.

Grade / form	Curcumin, HPLC (illustrative)	ASTA color value (illustrative)	Moisture, max	Typical use
Whole finger, export grade	3.0% to 5.0%	120 to 145	10%	Whole spice, in-house grinding
Whole bulb / round	2.5% to 4.0%	100 to 130	10%	Blending, lower-tier powder
Standard ground powder	2.5% to 4.5%	130 to 160	9%	Retail masalas, spice blends
High-curcumin powder	4.5% to 6.5%+	150 to 190	8%	Premium blends, nutraceutical use

The ranges above are illustrative trade ranges only, not guaranteed laboratory values and not a substitute for a per-lot certificate of analysis. Curcumin and ASTA color vary by crop year, growing conditions, and processing, and must be confirmed by HPLC and spectrophotometric testing on the specific lot before shipment. ODOD LLC provides a certificate of analysis with each quotation so the buyer can verify the figures against the lot actually booked.

What causes turmeric price and availability to swing during the year?

Price and availability move mainly with the old-crop-to-new-crop transition, currency movements, and demand spikes tied to festival and seasonal cooking calendars in importing markets.

In the weeks before new crop is released, old-crop stock tightens and quality can be less consistent, since the best material has usually already moved. Once new crop is released, supply eases and pricing typically stabilizes, though the first arrivals can carry a short-term premium before volume builds. Beyond the crop cycle, currency movements against the US dollar affect landed cost independent of the physical market, and demand spikes around major buying seasons in importing countries can tighten container and vessel space regardless of how much turmeric is available. ODOD LLC does not quote prices in advance of a formal quotation, since final pricing depends on grade, quantity, and destination port; buyers should request a quotation for current terms rather than rely on general market commentary.

What should a buyer confirm before booking a turmeric shipment?

A buyer should confirm crop year, curcumin and ASTA targets, moisture cap, particle size for powder, packaging, and certification before booking, since these terms determine whether the lot fits the intended finished product.

For powder, particle size is usually specified as a mesh range appropriate to the application, for example fine mesh for retail sachets versus a coarser mesh for industrial blending lines. Packaging is typically multiwall paper bags with a polyethylene liner for whole and ground turmeric, though bulk buyers supplying blenders may request jumbo bags depending on volume. Minimum order quantity typically runs from 500 kg to a full container load depending on the product and packing format. Buyers who also purchase finished curry bases built around turmeric, such as Biryani Paste or Chettinad Curry Sauce, often combine those orders with raw turmeric bookings to consolidate a container. Buyers formulating masalas that pair turmeric with a souring agent for color and tang commonly source Amchur (Mango) in the same shipment.

What documents accompany a turmeric shipment to the US?

A turmeric shipment is accompanied by a standard set of commercial, quality, and regulatory documents that the buyer's customs broker will require to clear the entry.

• Commercial invoice and packing list
• Bill of lading (ocean) or air waybill, depending on mode
• Certificate of analysis confirming curcumin, ASTA color, moisture, and microbial limits for the specific lot
• Certificate of origin, issued as applicable to the contract
• Phytosanitary certificate, where required by the importing authority
• Fumigation certificate, where treatment has been applied
• Certifications held by ODOD LLC covering US FDA registration, ISO, Halal, HACCP, and GMP, provided with each quotation

ODOD LLC states the origin of each lot on the quotation and on the shipping documents issued for that booking; this detail is not published in general marketing content and varies by contract and season.

Buyers planning a turmeric order around the annual crop cycle, or combining it with pastes, sauces, or other spices in the same container, can request a quotation for current grade options, packing formats, and lead times.
