A residue finding is the most expensive way to lose an organic consignment. The lot is decertified, the buyer's market may reject it, and your certification record carries the finding into every future risk assessment. NPOP sets out how testing works; the rest is prevention.
NPOP's testing rules
- 5%Of all operators under a certification body, sampled and tested every year — at the body's cost
- 2%Of farmers in every grower group, sampled in addition
- ISO 17025Testing only in accredited, APEDA-recognised laboratories
- DestinationExport testing parameters are set by the importing country's requirements
How Sampling Works
- Every year, each certification body must sample and analyse at least 5% of the operators under its control for unauthorised substances, and in addition samples from at least 2% of farmers in each grower group. The certification body bears the cost of the mandatory 5%.
- Where the use of unauthorised products or techniques is suspected, samples are taken and tested in every such case, over and above the 5%.
- Sampling is third-party, drawn by trained laboratory personnel or the certification body's inspector, with procedures to stop samples being contaminated before testing.
- Sampling is risk-based and covers all stages — production, processing and chain of custody.

What the Laboratory Tests For
Testing must be done in ISO 17025-certified, APEDA-recognised laboratories, accredited for the entire range being tested. The range of unauthorised substances must follow the importing country's requirements as notified from time to time, and for export consignments the testing parameters are fixed to the importing country's requirements. APEDA can also direct additional testing based on risk, or on complaints from importing countries.
Test against the destination's list, not a generic panel. A consignment can pass an NPOP-scope test and still fail at an EU port on a substance the EU looks for and the panel did not include. The best-known case is ethylene oxide: in 2020 EU authorities found it in sesame seeds from India, which led to large product recalls across Europe.
If a Residue Is Found
Where an infringement affecting organic integrity is found, the certification body must ensure the non-compliant lot is removed from the entire lot of the production cycle affected. For serious non-compliances, certification is withdrawn for a specified period; for severe or repeated violations, it is terminated. The certification body informs APEDA and publishes the decision on its website. Sanctions and your right of appeal are covered in episode 19.
- Lot removedThe non-compliant lot is removed from the entire lot of the affected production cycle.
- WithdrawalFor serious non-compliances affecting organic integrity, certification is withdrawn for a specified period.
- TerminationFor severe infringement or repeated violations, certification is terminated.
- Made publicThe certification body informs APEDA and publishes the decision on its website.
Where Contamination Comes From
| Source | Prevention |
|---|---|
| Drift from neighbouring conventional fields | Buffer zones, documented and maintained |
| Contaminated or treated seed | Certified organic seed, or documented untreated seed where permitted |
| Shared equipment or storage | Separation in time or place, cleaning records |
| Storage and port fumigation | Check what treatments warehouses, containers and ports apply before booking |
| Bought-in material | Upstream TCs verified, supplier testing where risk is high |
Keeping a Consignment From Being Rejected
Pre-shipment residue checklist
- Get the destination's residue list and limits from your buyer before production, not before shipping.
- Test pre-shipment in an ISO 17025, APEDA-recognised laboratory accredited for that full range.
- Keep the test report in the shipment file, matched to the lot and the TC.
- Find out whether your product and origin are under additional official controls in the EU — see the EU episode.
- Treat any positive result upstream as a supplier problem to resolve, not a lot to blend away.
