EOS-Forordning Skill

Expert knowledge of EU/EEA social security coordination regulations (EC) No 883/2004 and 987/2009.

Quick Reference

Regulatory Framework

Regulation	Full Name	Purpose
(EC) No 883/2004	Basic Regulation	Coordination rules for social security
(EC) No 987/2009	Implementing Regulation	Procedures and implementation details
EEA Agreement	Annex VI	Extends EU regulations to EEA countries
Separasjonsavtalen	Withdrawal/Separation Agreement (art. 29/30)	Keeps 883/2004 & 987/2009 in force for pre-2021 NO-UK cross-border situations
EØS/EFTA-UK-konvensjonen	EEA EFTA Convention (kodeverk KONV_EFTA_STORBRITANNIA_*, art. 13-18)	Post-Brexit basis for new NO-UK cases (in force from 01.01.2024). Note: Norway is NOT party to the EU-UK TCA.

Core Principles

Principle	Description	Implementation
Single Legislation	Person subject to ONE country's legislation only (Art. 11.1)	Lovvalgsperiode has single lovvalgsland
Lex Loci Laboris	Work location determines legislation (Art. 11.3.a)	Default for employed persons
Equal Treatment	No discrimination based on nationality (Art. 4)	Same rights as national citizens
Aggregation	Periods from all countries count (Art. 6)	For qualifying for benefits
Export of Benefits	Benefits paid regardless of residence (Art. 7)	No residence requirements

Personal Scope (Art. 2)

The regulations apply to:

Category	Description
Nationals	EU/EEA/Swiss nationals subject to member state legislation
Stateless/Refugees	Residing in EU/EEA, subject to member state legislation
Family Members	Covered for derived rights (healthcare, survivors)
Third-Country Nationals	At EU level (Reg. 1231/2010) when legally resident and moving within EU. NOT adopted by Norway — for Norwegian cases a plain TCN is generally outside the personkrets of 883/2004, and only covered via the Nordic Convention or the NL/LUX/AT bilateral agreements.

Material Scope (Art. 3)

Benefits covered:

Branch	Norwegian Coverage
Sickness	Folketrygden + Helfo
Maternity/Paternity	Foreldrepenger
Old-age	Alderspensjon
Invalidity	Uføretrygd
Survivors	Etterlattepensjon
Accidents at Work	Yrkesskade
Unemployment	Dagpenger
Family	Barnetrygd, kontantstøtte
Pre-retirement	N/A in Norway

Territorial Scope

Territory	Regulation Basis	A1 Validity
EU-27	Direct application of 883/2004	Full
EEA (NO, IS, LI)	EEA Agreement Annex VI	Full
Switzerland	EU-Switzerland Agreement (applies from 01.01.2016)	Full
UK	Separasjonsavtalen (pre-2021 cases) + EØS/EFTA-UK-konvensjonen (new cases)	Convention-based (NOT the EU-UK TCA — Norway is not a TCA party)

Sakstype Handling

EU_EOS vs Other Types

Sakstype	Regulation	Service	Key Difference
EU_EOS	883/2004	EosVedtakService	EESSI integration, SEDs
TRYGDEAVTALE	Bilateral agreements	TrygdeavtaleVedtakService	Country-specific articles
FTRL	Folketrygdloven	FtrlVedtakService	National law, no EESSI

EU_EOS Processing

// In FattVedtakVelger.getFattVedtakService(behandling)
// ÅRSAVREGNING short-circuits before the sakstype branch
if (behandling.type == Behandlingstyper.ÅRSAVREGNING) {
    return årsavregningVedtakService
}

return when (behandling.fagsak.type) {
    Sakstyper.EU_EOS -> eosVedtakService
    Sakstyper.FTRL -> ftrlVedtakService
    Sakstyper.TRYGDEAVTALE -> trygdeavtaleVedtakService
}

EU_EOS cases:

• Use 883/2004 articles (FO_883_2004_ART*)
• Integrate with EESSI via EUX
• Generate EU A1 certificates
• Exchange SEDs with other institutions

Title II - Applicable Legislation

The key articles for determining legislation:

Article	Scenario	Result
Art. 11	General rule - work in one country	Country of work
Art. 12	Posted workers	Sending country (max 24 months)
Art. 13	Multi-state work	Residence if substantial, else employer
Art. 14	Voluntary insurance	Optional additions
Art. 15	Contract agents	Choice of legislation
Art. 16	Exceptions	Agreed exception

For detailed article descriptions, see the lovvalg skill.

Implementing Regulation 987/2009

Key procedural articles:

Article	Topic	Purpose
Art. 14	Supplementary provisions for art. 12 AND art. 13	Clarifying criteria (e.g. the 25% substantial-activity test is art. 14(8))
Art. 15	Procedure for applying art. 12	Posting procedure
Art. 16	Multi-state procedure	Art. 13 determination process
Art. 18	Exception procedure	Art. 16 application process

Art. 14.11 - Business Outside EEA

When employer has no registered office in EEA:

Kodeverk: FO_987_2009_ART14_11
Result: Employee's residence country determines legislation

EESSI Integration

Portable Documents and AC Decisions

Do not confuse the Portable Document with Administrative Commission (AC) Decisions:

Item	Type	Relevance
PD A1	Portable Document	The attestation of applicable legislation issued for posted/multi-state workers (the result of LA_BUC processing)
Decision A2	AC Decision	Interpretation of the posting rules (art. 12)
Decision A3	AC Decision	Aggregation of uninterrupted posting periods

The PD A1 is the document NAV produces; AC Decisions are interpretive guidance from the Administrative Commission, not documents exchanged per case.

BUC Types by Article

Article	BUC	Purpose
Art. 11	LA_BUC_05	Legislation notification
Art. 12	LA_BUC_04	Posted worker notification
Art. 13	LA_BUC_02	Multi-state decision
Art. 16	LA_BUC_01	Exception request

Debugging Queries

Schema note: fagsak PK is saksnummer (string); the sakstype column is fagsak_type. behandling joins fagsak via the saksnummer FK column (there is no fagsak_id), and orders by registrert_dato. BUC/SED documents are NOT stored in the melosys-api database — they live in melosys-eessi.

Find EU_EOS Cases

SELECT f.saksnummer, f.gsak_saksnummer, b.id as behandling_id, b.status
FROM fagsak f
JOIN behandling b ON b.saksnummer = f.saksnummer
WHERE f.fagsak_type = 'EU_EOS'
ORDER BY b.registrert_dato DESC
FETCH FIRST 50 ROWS ONLY;

Check Lovvalgsbestemmelse Used

SELECT lp.id, lp.lovvalg_bestemmelse, lp.fom_dato, lp.tom_dato, f.gsak_saksnummer
FROM lovvalg_periode lp
JOIN behandlingsresultat br ON lp.beh_resultat_id = br.behandling_id
JOIN behandling b ON br.behandling_id = b.id
JOIN fagsak f ON b.saksnummer = f.saksnummer
WHERE f.fagsak_type = 'EU_EOS'
AND lp.lovvalg_bestemmelse LIKE 'FO_883%'
ORDER BY b.registrert_dato DESC;

UK Post-Brexit

After Brexit, UK cases use:

Period	Legal basis	Kodeverk
Pre-2021 cross-border situations	Separasjonsavtalen (art. 29/30) keeps 883/2004 & 987/2009 in force	FO_883_2004_*
New cases (EØS/EFTA-UK-konvensjonen, in force from 01.01.2024)	EEA EFTA Convention (art. 13-18) — NOT the EU-UK TCA, which Norway is not party to	Lovvalgbestemmelser_konv_efta_storbritannia
