Typical proposal-form questions
- Under which Suva or private-insurer hazard class and sub-class is the business activity currently classified?
- Has the mix of activities at the location changed in a way that could justify a reclassification?
- Are there separate hazard classes for distinct operational units within the same legal entity?
Evidence
- Suva/UVG business description (Betriebsbeschreibung)
- Suva classification decision (Einreihungsverfügung)
- Site activity and process description
Why it matters for underwriting
The hazard class assigned by Suva, or by a private UVG insurer for accredited employers, sets the base rate that is multiplied by the wage sum to derive the occupational accident premium. Because accident frequency and severity vary enormously between, for example, office administration and construction or metalworking, the classification is the single biggest lever on premium after the wage sum itself. Misclassification distorts pricing for the insurer and can leave the employer exposed to a large retroactive correction if a subsequent audit reveals that actual activities carry a higher hazard class than declared.
Capturing the attribute and evidence
Underwriters determine the applicable class from the business description, which details the operational activities, machinery, materials handled and staff functions at each site. Suva issues a formal classification decision (Einreihungsverfügung) that assigns the class and sub-class; private insurers apply an analogous tariff. Where an employer runs several distinct operational units, each may be classified separately, and underwriters review site visit notes or process descriptions to confirm the classification remains accurate as operations evolve.
Effect on coverage, premium and conditions
The hazard class is the primary driver of the occupational accident premium rate; it can also affect eligibility for experience-rating (bonus-malus) adjustments over time. A class that understates true operational risk typically triggers a reclassification and retroactive premium correction rather than a coverage exclusion, since UVG cover itself is mandatory and cannot be denied.
Mitigation measures
Employers should keep the business description current whenever activities, processes or machinery change materially, proactively notify Suva or the insurer of new higher-risk operations, and periodically review the classification against actual site activities to avoid disputes or retroactive premium adjustments at audit.
