Relevant operators in the certified seed sector have new obligation dates as of July 2, 2026. The Resolution of June 22, 2026, from the General Directorate of Agricultural Production and Markets, modifies the Resolution of September 27, 2022 and completely redefines the communication calendar to the SIEGA system for certified seed stocks of cereals, rice, oilseeds and protein crops.
The change responds to EU Regulation 2024/2391, which adapted European deadlines to the real harvest and sowing cycle. The previous mid-year deadline did not adequately reflect the actual availability of seeds in the market, generating reports misaligned with productive reality.
What does this regulation establish?
The resolution replaces the previous communication calendar with a system of four mandatory annual dates, aligned with the real agricultural cycle. Below is the complete detail of the new deadlines:
| Report | Maximum deadline | Data reference |
|---|---|---|
| Certified seed stocks (1st annual report) | Before February 15 | Last day of previous month (January 31) |
| Certified seed stocks (2nd annual report) | Before September 15 | Last day of previous month (August 31) |
| Area accepted for certification | Before November 15 | Current campaign |
| Quantity harvested for certification | Before January 15 of the following year | Completed campaign |
The products affected by these reporting obligations are:
- Certified cereal seeds
- Certified rice seeds
- Oilseed seeds
- Protein crop seeds
The previous regulation, from September 2022, established a communication deadline centered on mid-year that did not align with the real seed availability cycle. The new calendar distributes obligations throughout the year to accurately reflect the actual state of stocks at each point in the agricultural cycle.
Economic and operational impact
The main impact of this resolution is operational and compliance-related, not directly economic. No fees, specific penalties or amounts are established in the text of the resolution. However, the real risk for operators is twofold:
- Risk of regulatory non-compliance by failing to adapt internal calendars to the new deadlines, which may result in sanctioning proceedings under the general regime for agricultural violations.
- Operational adaptation cost: administration and logistics teams must reprogram their counting, validation and data upload processes to SIEGA to meet the four annual dates.
The most relevant change in terms of internal management is the incorporation of two new specific reports (area accepted for certification before November 15, and quantity harvested before January 15), which were not previously disaggregated with these specific deadlines. This requires reviewing internal data flows and warehouse or production management systems that feed the SIEGA report.
Who does it affect?
- Certified seed producers of cereals, rice, oilseeds and protein crops registered as relevant operators in SIEGA.
- Wholesalers with certified seed stocks of the indicated types.
- Commercial agents operating with certified seeds and registered as relevant operators.
- Compliance and administration managers of agricultural sector companies that manage periodic communications to the administration.
- Advisors and management firms providing regulatory compliance services to seed sector companies.
Practical example
A producer and wholesaler company of certified wheat seeds (cereal) and sunflower (oilseed) registered in SIEGA previously had a single reporting point around mid-year. With the new deadlines, its annual calendar is now as follows:
| Deadline | What must be reported |
|---|---|
| January 15 | Quantity harvested for certification from the previous campaign |
| February 15 | Certified seed stocks as of January 31 |
| September 15 | Certified seed stocks as of August 31 |
| November 15 | Area accepted for certification of the current campaign |
This company must review its warehouse management systems to ensure that stock data is available and validated before each of these dates, and not just once a year as could occur under the previous regime.
What should companies do now?
- Verify SIEGA registration: confirm that the company is registered as a relevant operator and that system access is active and up to date.
- Update the internal reporting calendar: incorporate the four key dates (January 15, February 15, September 15 and November 15) into management systems and administration team reminders.
- Review stock counting processes: ensure that stock data as of January 31 and August 31 can be obtained and validated with sufficient advance notice to meet the February 15 and September 15 deadlines respectively.
- Adapt production data flows: data on area accepted for certification (deadline: November 15) and quantity harvested (deadline: January 15) must be integrated into campaign closing processes.
- Inform external advisors and managers: if SIEGA reporting is delegated to a management firm or advisory service, communicate the new deadlines immediately to avoid non-compliance due to lack of awareness.
- Keep records of each report: save receipts or confirmations from the SIEGA system for each of the four annual reports, as evidence of compliance in case of inspections.
Frequently asked questions
What are the new SIEGA reporting dates for certified seeds?
Four annual dates are established: before February 15 (stocks as of January 31), before September 15 (stocks as of August 31), before November 15 (area accepted for certification) and before January 15 of the following year (quantity harvested for certification).
What products are affected by the SIEGA reporting obligation?
Operators must report stocks of certified seeds of cereals, rice, oilseeds and protein crop seeds. The obligation applies to all relevant operators registered in SIEGA that have stocks of these products.
Why are the certified seed reporting deadlines changing in 2026?
The change responds to EU Regulation 2024/2391, which adapted European deadlines to the real harvest and sowing cycle. The previous mid-year deadline did not adequately reflect the actual availability of seeds in the market, so the calendar has been redistributed throughout the year.
When do the new SIEGA deadlines for seeds become mandatory?
The new deadlines apply as of July 2, 2026, the publication and entry into force date of the Resolution of June 22, 2026 from the General Directorate of Agricultural Production and Markets.
What regulation does this resolution modify and what changes from the previous one?
It modifies the Resolution of September 27, 2022, which established technical criteria for relevant operators and electronic communication means. The main change is the replacement of the previous calendar (with a deadline centered on mid-year) with four annual dates distributed throughout the real agricultural cycle.
