Consortium Requirement:The procurement documents reference tenderer qualification requirements and selection criteria that typically allow either single economic operators or consortia/subcontracting arrangements. The lot metadata and selection templates indicate specific tenderer requirements must be demonstrated, but a mandatory multi-party consortium is not explicitly specified in the high-level metadata. Bidders should consult the Tender Specifications and Template selection criterion (Annex 8) for precise rules on joint bids, subcontracting, and eligible forms of tenderers.

Beneficiary Scope (Geographic Eligibility):The contracting authority is ECHA, an EU agency. The procurement is published on the EU Funding & Tenders Portal and follows EU procurement rules. Eligible tenderers are those able to enter into contracts with EU bodies; typically this includes organisations established in EU Member States and possibly EEA and certain third countries complying with the procurement rules and participation conditions set in the tender dossier. Tenderers must verify nationality and establishment rules in the Tender Specifications and Invitation to Tender documents.

Target Sector:Primary sector: chemicals and regulatory science, specifically nanomaterials risk assessment. Secondary sectors: environmental health and safety, toxicology, materials characterisation, analytical chemistry, regulatory compliance under REACH, and scientific data analysis. CPV codes listed include 73000000 (research and development services and related consultancy services), 71313000 (chemical analysis services), and 90711100 (research and development services in physical sciences).

Geographic scope should be treated as EU/EFTA/eligible third countries in accordance with procurement participation rules in the tender documents.

Project Stage:Expected maturity: data analysis, validation and guidance development. The work requires analysis and validation of existing thresholds using additional experimental and literature data sets. Activities are at development/validation/demonstration stages rather than early-stage idea generation or pure laboratory discovery; the output is intended to support regulatory guidance (applied regulatory science).

Funding Amount:Estimated overall contract amount: €160,000 (this is the estimated total procedure value published with the tender). Bidders must submit a financial offer using the provided Annex 6 - Financial offer template.

Application Type:Application method: open competitive tender via the EU Funding & Tenders Portal. Submission method code: ESUBMISSION (electronic). The call is publicly accessible on the portal and allows submissions until the published closing date.

Nature of Support:Beneficiaries will receive monetary remuneration through a service contract (payment for deliverables and activities) if awarded. The procurement is for contracted services (money for services).

Application Stages:The tender process follows a single-stage submission and evaluation typical for service contracts: bidders submit selection and award documentation by the closing date, the contracting authority evaluates selection criteria (eligibility and capacity) and award criteria (quality and price). The metadata lists awarding criteria weights in summary: quality 60 and price 40, but bidders must consult the tender specifications for full award evaluation methodology. There is an open tender event scheduled on the day of closing for clarification. Thus operationally applicants pass 1 formal submission stage and then evaluation; overall this is a 1-stage tender process (with possible clarifications and negotiations as provided in the tender rules).

Success Rates:The tender record does not disclose historic success rates or number of expected awards. As a single-lot procurement with an estimated contract value of €160,000 and standard EU procurement competitive procedures, success rates depend on the number and quality of bids received.

What the tender is about

The contract is a follow up to the 2023 ECHA project on sameness and grouping approaches for nanomaterials, which developed a framework based on binary decision trees and variability thresholds for the mandatory nanoform characterisers. The new work is intended to refine those threshold values and validate them using additional datasets that cover a wider range of chemical types. [1][2]

This topic sits within the REACH nanoform framework, where nanoforms are characterised through parameters such as size distribution, shape, surface treatment or functionalisation, and specific surface area. EU law also allows similar nanoforms to be grouped into sets when the variation is justified and shown not to affect hazard, exposure, or risk assessment. [6][9][22][23]

Who can apply

The opportunity is a services procurement for research and development services and environmental technical consultancy, so it is aimed at economic operators that can deliver scientific, regulatory, or technical work in nanomaterial risk assessment. The tender summary marks the opportunity as suitable for SMEs and indicates that performance can take place anywhere in the European Economic Area. [2]

Contract structure and value

Why this tender matters

1. 1It may shape future ECHA guidance for registrants of nanoforms of a substance. [2]
2. 2It addresses a central regulatory issue, because acceptable variation thresholds determine when a material can still be treated as the same nanoform and when it should be considered distinct. [6][9][23]
3. 3It builds directly on earlier decision tree and threshold work, which suggests that strong expertise in nanoform characterisation, data validation, and regulatory interpretation will be important. [1][2]

Practical bidder considerations

Applicants should be prepared to demonstrate competence in nanoform characterisation, quantitative assessment of variability, and validation across multiple chemical classes. Because quality carries a 60 percent weighting and price 40 percent, the technical soundness of the proposed methodology is likely to be more important than offering the lowest price alone. [2][6][9]
