Farm-to-lot spray records and residue test plans for spice exporters
TL;DR Peppertrail ties each export lot of chilli, cumin or turmeric to the farms, traders and processing steps behind it, so an exporter knows where residue risk sits before testing. Exporters pay a yearly fee per supply cluster. One rejected container can cost more than a year of the service.
India shipped about 17.34 lakh tonnes of spices worth ₹39,140 Cr in 2025-26, and chilli alone was 27% of the value[1]. Most of it starts on small farms and passes through several traders before an exporter cleans and packs it. When a buyer finds a pesticide or ethylene oxide residue, the exporter usually cannot say which farm or which trader the problem came from.
Rejections are a small share of shipments, under 1% of samples in major markets by one count[2]. Not everything is hunky-dory though, and the 2024 ethylene oxide cases in Hong Kong and Singapore showed that a few failures can put a whole country's spices under scrutiny. The Spices Board now tells exporters to treat ethylene oxide as a critical hazard and test raw material, packaging and finished goods[3].
First, the regulatory bit - Peppertrail does record-keeping and test planning that helps exporters meet buyer-country residue limits and Spices Board guidance. It does not test samples or certify safety, and accredited labs do the testing.
An exporter's buying team logs each purchase on a phone - trader, village, quantity and date. Where the exporter runs a contract-farming or FPO programme, field staff add spray records for each farm. Every lot in the warehouse then carries its source list. The software ranks incoming lots by risk, using past lab results by village and trader, and suggests which to test before blending. If a buyer flags a residue then the exporter can pull the affected sources within an hour and show the buyer what changed.
The original idea was blockchain and AI traceability for all food. I've narrowed it to spice exports, where the money at risk is clear, and dropped the chain, because a database with an audit log does the same job and buyers ask for records, not tokens.
The payer is a mid-size spice exporter, usually one with ₹50–500 Cr in sales and a quality manager who already handles buyer audits. Price it per supply cluster per year, plus a setup fee. I found no public price for comparable software, so test willingness to pay against the exporter's own testing bill, which they know down to the rupee.
The 2024 ethylene oxide cases made buyers and regulators ask for proof of source, and the Spices Board's guidelines followed[3]. Spice export volume fell 4% in 2025-26[1], which makes keeping existing buyers more urgent than chasing new ones. No Codex limit for ethylene oxide exists yet, so buyer-specific limits will keep changing[2].
There's no public figure for what India spends on spice traceability or residue testing. The firmest number is the size of the trade at risk - ₹39,140 Cr of exports in 2025-26, with chilli, cumin and turmeric making up 46% of value[1]. India held 12% of global spice exports in 2023-24[2]. Treat these as the value being protected, not as your market size.
One global traceability firm lists spices among the crops it covers[4]. An Indian authentication firm sells track-and-trace for agro and food products, aimed mainly at packaging-level authentication[5]. Large exporters run in-house quality systems. The gap is a tool built around residue risk for mid-size exporters who buy through traders and cannot afford an in-house traceability team.

The software is modest. The hard part is getting traders to name their villages and farmers, since that information is their bargaining power. A useful risk score also needs a season or two of lab results tied to sources. Until then the product is a record book, and you have to price it like one.
You need no licence of your own. Your customers hold the export registrations, and your job is to fit their rules.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't trust a risk score to replace a lab test. It decides what to test first, never what to ship.

Here's what can go south -
I'd say this is worth trying for a founder with spice-trade or food-quality experience in Guntur, Unjha or Kochi. It is a poor fit for a software-only team. Prove first that one exporter will log every purchase for a full season, and that a buyer values the records in an audit.
Plan for about ₹45–80 L, mostly field staff in the spice belts, a simple app and a season of lab results to build the risk score.
Not for yourself. Your exporter customers hold Spices Board registration and follow its ethylene oxide guidelines, and you must handle farmer data under the DPDP Act.
Yes, in any country exporting spices through traders to strict markets. Find that country's spice authority and its residue rules first.

Thinking about building Peppertrail or something close to it? The make-or-break work is getting traders to share their sources without feeling cut out, and I'm happy to help you think that through. If you need a hand, you know where to find me. Talk to Yash →
