Posting crews, subcontracting across borders, or staffing an EPC project site? Auxilai's compliance engine resolves the actual instruments — posting notifications, A1 certificates, chain liability, sectoral CBAs — per corridor, grounded in official sources.
Every instrument below comes from a live run of the compliance engine — nothing is illustrative.
The same subcontracting chain triggers a different instrument — or deliberately none — depending on the country. The engine names the one that actually applies.
| Corridor | Instrument | What your client/principal faces |
|---|---|---|
| Germany | Auftraggeberhaftung — MiLoG §13 i.V.m. §14 AEntG | Statutory liability for minimum wage + joint-fund contributions down the chain |
| Belgium | Law of 12 April 1965 | Wage chain liability — construction direct-relationship scheme + general RD-designated scheme |
| France | Donneur d'ordre — L.8222-1 et seq. | Vigilance attestations (contracts ≥ €5,000) + joint-and-several liability for wages, contributions, taxes |
| Netherlands | Ketenaansprakelijkheid | Chain liability for wage payment in construction |
| Ireland | Construction chain liability | Subcontractor wage liability in construction |
| Denmark | No chain-liability statute — AFU wage fund | Jointly funded wage-protection scheme; contribution duty per FTE |
| Finland | No wage liability — tilaajavastuu + Act 447/2016 §15 | Verification duties (7 document categories, negligence fee up to €79,380) + construction duty-to-inquire |
| Norway | Solidaransvar | Joint liability under generally-applied (allmenngjort) collective agreements |
Construction: TV Mindestlohn Baugewerbe (DE) · JC 124 (BE) · Bouw-CAO (NL) · CCN Bâtiment (FR) · allmenngjøring (NO) · yleissitovuus generally-binding agreements (FI).
Engineering & EPC: extended CCNs (conventions collectives étendues) apply to posted workers in whichever branch the work falls — the engine surfaces the applicable framework per scenario.
UK employers posting into the EU face the third-country stack: work authorisation (no free movement), TCA certificates of coverage (HMRC PD A1 via CA3822) before departure, and the full posting machinery (SIPSI, LIMOSA, Meldepflicht) unchanged. The engine treats UK as its own employer class — TCA-specific rules fire automatically.
