Abstract
European chemicals legislation – while among the most advanced in the world – still needs tools for bringing greater consistency to the substance evaluation processes. This article explores the elements of the ‘essential use’ concept – as proposed by the Montreal Protocol – in the European framework. The Treaty on the Functioning of the European Union provides context to understanding ‘health’, ‘safety’, and ‘functioning of society’ in order to then view how these elements are reflected within Union legislation and case law. In the balancing of EU priorities, examples exist where importance is given through exemptions and derogations to sectors within the categories of health, safety, and societal advancement. This demonstrates the possibility of the concept to help define essentiality and to determine specific uses that may be deemed essential.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
