Rice, from the paddy field to the milled lot.
Record paddy by plot and season, keep drying and milling linked to every input, and see the milling runs whose yield falls outside the expected range.

The challenge
Paddy loses water before it is milled, and milling takes off husk and bran.
Harvested wet
Paddy is often harvested wet and dried before storage, so its weight changes before it reaches the mill.
Milling yield
Hulling and polishing turn paddy into milled rice, broken rice, bran and husk; the share of milled rice says how the run went.
Blends at the mill
A mill lot can hold the paddy of many farms and seasons.
Products used
How A-REX runs rice, step by step.
01
Register harvests
Register paddy by plot and season in the unit your people use, recorded exactly in kilograms. A crop sold before harvest can wait as Not yet harvested.
- Tonnes or bags, recorded exactly
- Each lot with its plot and season
Fictitious demo data 02
Field work and weather
Record planting, flooding, applications and drainage on each plot, with the rain and temperature at the plot that day and the next. Rain right after an application reads Wash-off risk.
- Weather at the plot, that day and the next
- Wash-off risk shown after an application
Fictitious demo data 03
Processing
Dry, merge and mill paddy into new lots that keep every input. A control flags milled rice outside the expected share of the paddy, and Humboldt explains the finding.
- Drying, merging and milling keep every input
- Milling yields out of range open a finding
Fictitious demo data 04
Lineage
Open a lot of milled rice to see the paddy and the plots behind it, and everything made from a lot. Follow it forward to every holder, even across companies.
- Back to the paddy and the plots
- Forward to every holder
Fictitious demo data 05
Readings
Temperature and humidity from a logger, a tracker or a connected platform are charted against the range agreed for the trip, with each excursion marked. Logger files in CSV, spreadsheet or PDF can be imported too.
- Humidity and temperature against the agreed range
- Logger files imported as they are written
Fictitious demo data 06
Tracked deliveries
Ship rice to a mill, a port or a buyer once your lot rules have checked the receiver, the certificates and the expiry. A tracked delivery keeps a custody record signed step by step and the route as recorded.
- Receivers, certificates and expiry checked first
- Custody signed step by step

The journey, stage by stage
Every step is a proposal a person approves.
Start from the rice chain
Rice with its HS codes, in tonnes, the schemes buyers ask about, such as the Sustainable Rice Platform and Organic, and what partners usually share: certificates and lab results.
Record the work on each plot
Planting, flooding, applications and drainage as field work you define, with the rain and temperature at the plot that day and the next.
Register paddy by plot and season
In tonnes, recorded exactly, each lot with the origin reference of its plot.
Dry and store, keeping the inputs
Drying makes a new lot that names the wet paddy, and the moisture can be kept as a fact on it.
Mill and check the yield
Milling makes lots that keep every input, and a control flags milled rice outside 55–80 % of the paddy.
Deliver with the certificates
Lot rules check the receiver, the certificates and the expiry before a lot leaves.
The evidence it produces
What a buyer, an auditor or a verifier you allow can read, with who declared each part.
- Lineage
- Each lot back to its inputs and their plots or farms, and forward to every holder.
- Mass balance
- Processing output against input, and the findings where it does not add up.
- Certificates and lab results
- Each with its issuer, its validity and its evidence level.
- Commodity codes
- Each product with the code of your country, from HS and NCM to CN and HTS.
- Recall scope
- Every lot, holder and quantity a recall reaches.
- EPCIS and UNTP
- Lot events as EPCIS 2.0, and the UNTP product passport of a lot.
An evidence check lists what the records hold. It is not a legal opinion and never says that a lot complies.
Regulation crosswalk
What each rule asks of you, and where the platform keeps it. Evidence, not a legal opinion.
| Rule | What it asks of you | Where the platform keeps it |
|---|---|---|
| Certification schemes | Organic and other schemes, as certificates a lot must carry. | Each certificate with its issuer and evidence level; a lot rule can stop a lot that lacks one. |
| National rules | Country profiles for what each jurisdiction asks for. | Product codes, units and records in the scheme of each country, from HS and NCM to CN and HTS. |
