Executive Summary

Croatia regulates the plumber — hvac trade through a layered statutory framework comprising the host-state Labour Code, the labour-migration statute, the spatial-development or construction-categorisation act, and EU-derived regulations transposed under accession treaty obligations. Cross-border deployment of plumber — hvacs into Croatia sites engages four concurrent regulatory layers: immigration authorisation, labour-migration registration with the host inspectorate, social-insurance affiliation under EU Regulation 883/2004, and firm-level construction qualification.

Plumber — Hvac as a stand-alone occupation in Croatia sits within the broader construction sector regulatory framework. Trade-specific recognition pathways operate under the Recognition of Professional Qualifications regime transposing Directive 2005/36/EC as amended by 2013/55/EU. HVAC plumbing including refrigeration and ventilation systems on multi-trade sites adds firm-level construction-qualification overhead and may engage trade-adjacent regulated activities such as welding (EN ISO 9606), lifting equipment operation, and pressure-equipment work depending on the site context.

Bottom line: Croatia is a Tier-1 wage destination for plumber — hvac deployment. Total deployment cost reflects high statutory minimum wage, sector-fund contributions where applicable, and qualification-recognition lead times. Pre-deployment compliance preparation reduces exposure to inspectorate-driven schedule disruption.

The Republic of Croatia (Republika Hrvatska) is a unitary civil-law jurisdiction whose labour-law architecture rests on a layered legacy: Austrian-Hungarian codifications transmitted through the Kingdom of Croatia-Slavonia, Yugoslav-era statutes consolidated 1945-1990, and post-1991 Croatian republican legislation re-codified after independence. Legislative competence sits with the Hrvatski sabor, with implementing rules issued by ministries through Pravilnici and by the Vlada Republike Hrvatske through Uredbe. The primary publication channel is the Narodne novine (Official Gazette) at https://narodne-novine.nn.hr/.

Croatia became the twenty-eighth EU Member State on 1 July 2013, adopted the euro on 1 January 2023 (replacing the kuna at 1 EUR = 7.53450 HRK under Council Regulation (EU) 2022/1208), and acceded to the Schengen area on 1 January 2023. All three transitions are material for deployment: euro adoption normalises salary documentation for wage-parity; Schengen removes internal-border controls while reinforcing SIS checks on third-country nationals; EU membership applies the full free-movement, posted-worker, and qualifications-recognition acquis.

The current landscape for non-EU workforce deployment rests on four statutes. (1) The Zakon o strancima (Aliens Act NN 133/2020 of 5 December 2020, amended by NN 114/2022 and NN 151/2022, consolidated at https://narodne-novine.nn.hr/clanci/sluzbeni/2020_12_133_2520.html), which abolished the prior annual quota for non-EU work permits and introduced the Dozvola za boravak i rad (single residence-and-work permit) under Articles 92-109. (2) The Zakon o tržištu rada (Labour Market Act NN 118/2018 with amendments) governing HZZ labour-market testing and active-employment measures. (3) The Zakon o radu (Labour Act NN 93/2014, NN 127/2017, NN 98/2019, NN 151/2022) transposing Directive 96/71/EC and Directive 2018/957/EU on posting of workers. (4) The Zakon o gradnji (Building Act NN 153/2013 with amendments) read with the Zakon o poslovima i djelatnostima prostornog uređenja i gradnje (NN 78/2015 with amendments). EU acts at https://eur-lex.europa.eu/.

The principal enforcement bodies are the Ministarstvo unutarnjih poslova (MUP, https://mup.hr/) for residence-and-work permits; the Državni inspektorat (DIRH, https://dirh.gov.hr/) for labour-law and posted-worker enforcement; HZMO (https://www.mirovinsko.hr/) for pension contributions; and HZZO (https://hzzo.hr/) for public health insurance. The 2018 establishment of DIRH consolidated previously fragmented inspectorate competences (labour, construction, sanitary, market, tourism) into a single body, materially raising enforcement capacity since 2019.

Trade-specific context

HVAC plumber installs the wet and refrigerant side of mechanical building services: chilled-water and condenser-water mains for fan-coils and AHUs, low- and medium-temperature heating loops for radiator and underfloor circuits, refrigerant lines (split, multi-split, VRF/VRV) between condensers and evaporators, condensate drains from cooling coils, and the associated insulation, expansion, balancing and commissioning works. Increasingly the rubric also covers heat-pump primary and secondary circuits (air-source, ground-source, water-to-water) installed under the EU REPowerEU retrofit wave.

The trade is bounded on three sides. It is distinct from plumber_commercial (potable cold and hot water, sanitary drainage, gas service pipework downstream of the meter, fire-main pre-pressure), and distinct from pipefitter_industrial (process EPC piping in refineries, petrochemical, food, pharma — high-pressure carbon and stainless welded systems to ASME B31.3 or PED 2014/68/EU). It is also distinct from the dedicated ductwork sheet-metal trade (Lüftungsbauer, ductwork erector) although in DE and AT the Anlagenmechaniker SHK qualification overlaps with both wet-side HVAC and limited ductwork installation.

The defining technical boundary is refrigerant. Any worker who breaks into a refrigerant circuit, recovers refrigerant, charges a system, or performs leak-checks on circuits containing fluorinated gases must hold an individual F-Gas certificate under EU Regulation 517/2014 (and the 2024 amendment 2024/573). The boundary is statutory across all 27 EU member states plus EEA. Without F-Gas Cat I, the worker is restricted to wet-side and condensate work and cannot legally touch the refrigerant side.

Bayswater treats HVAC plumber as a high-value rubric distinct from commercial plumbing because data-centre, pharmaceutical, and heat-pump retrofit projects in Germany, Ireland, the Netherlands and the Nordics are bid against this specific scope, and because the F-Gas certificate represents a non-substitutable regulatory entry barrier.

Industry-Specific Compliance Stack

For plumber — hvac deployment to a Croatia site, the four-layer compliance stack — immigration authorisation, posting notification, social-insurance affiliation, and firm-level qualification — operates concurrently. Failure on any single layer can trigger inspectorate enforcement.

The Republic of Croatia (Republika Hrvatska) is a unitary civil-law jurisdiction whose labour-law architecture rests on a layered legacy: Austrian-Hungarian codifications transmitted through the Kingdom of Croatia-Slavonia, Yugoslav-era statutes consolidated 1945-1990, and post-1991 Croatian republican legislation re-codified after independence.

The Dozvola za boravak i rad operates as the principal single-permit instrument under Directive 2011/98/EU, replacing the bifurcated radna dozvola + dozvola za boravak architecture. The 2020 reform (NN 133/2020) abolished the prior annual quota system under the legacy NN 130/2011, replacing it with a labour-market test administered by HZZ under Article 105. Where HZZ confirms unavailability of EU/EEA/EFTA workers within an eight-day testing window, MUP issues the single permit. Government-listed deficit occupations and sector exemptions allow direct application without the labour-market test [verify 2026 Pravilnik o popisu zanimanja]. Permit validity is up to two years, renewable. References: https://narodne-novine.nn.hr/clanci/sluzbeni/2020_12_133_2520.html ; https://mup.hr/.

The Plava karta EU under Articles 110-117 transposes the recast EU Blue Card Directive (EU) 2021/1883 (replacing Directive 2009/50/EC from 18 November 2023). The salary floor is 1.5x the DZS average gross monthly wage for the preceding calendar year [verify 2026 DZS Priopcenje 9.1.1 + MUP Pravilnik]. References: https://mup.hr/ ; https://dzs.gov.hr/.

The Sezonski rad pathway is materially active because of dual seasonal demand: the Adriatic tourism corridor (Split, Dubrovnik, Istria, Kvarner) generates May-October hospitality and ancillary-construction demand; shipbuilding repair-and-conversion cycles at Brodosplit, Brodogradilište Viktor Lenac, and 3. Maj Rijeka generate demand for welders, fitters, pipefitters, and scaffolders pulled historically from BiH, Serbia, North Macedonia, and increasingly the Philippines, Nepal, and India. Seasonal title is restricted to listed activities and is not appropriate for year-round industrial-construction deployment.

3. Professional Recognition & Certification

Plumber — Hvac as a stand-alone occupation in Croatia typically does not carry an individual ordinal-registration requirement, though some host states (notably Germany under HwO Anlage A) impose Meisterzwang or equivalent qualification gates for specific construction trades. The Recognition of Professional Qualifications regime transposes Directive 2005/36/EC as amended by 2013/55/EU.

For EEA-issued plumber — hvac certificates, recognition flows under the automatic or general systems with typical processing of 2-6 weeks. For non-EEA certificates, equivalence assessment by the host-state competent authority typically runs 4-12 weeks and may require supplementary assessment via a designated host-state VET centre.

Construction activity is regulated under three intersecting statutes. The Zakon o gradnji (NN 153/2013 with amendments NN 20/2017, NN 39/2019, NN 125/2019) defines the building-permit regime, classifies works by complexity, and establishes the framework for stručni nadzor (professional supervision) and izvođač radova (works contractor) competences. The Zakon o poslovima i djelatnostima prostornog uređenja i gradnje (NN 78/2015, NN 118/2018, NN 110/2019) regulates the occupational eligibility framework, including the requirement for named responsible engineers (glavni projektant, glavni inženjer gradilišta, voditelj radova) to be chamber members.

The principal professional chamber is the Hrvatska komora inženjera građevinarstva (HKIG) at https://www.hkig.hr/, administering the registry of ovlašteni inženjer građevinarstva and ovlašteni voditelj građenja, with parallel chambers HKA (architects), HKIS (mechanical), HKIE (electrical). HKIG authorisation attaches to named individuals at engineer / supervisor level — gatekeeper for stručni nadzor and voditelj građenja roles. Worker-level mason, pipefitter, scaffolder, and welder activity does not require individual chamber registration; it operates under the firm-level licence of the registered izvođač radova.

For lifting equipment, pressure vessels, and classified technical equipment, supervision operates through the Državni inspektorat (DIRH) via its inspekcija rada and inspekcija opreme functions, with periodic technical inspections delegated to accredited inspection bodies. Unlike the Polish UDT or Czech TIČR systems, Croatia does not operate a single integrated technical-equipment authority — responsibility is distributed between DIRH, the Hrvatska obrtnička komora (HOK at https://hok.hr/) for certain craft-trade attestations, and conformity-assessment bodies. Crane, scaffold, and welding qualifications carried by non-Croatian workers are accepted at site induction subject to firm stručni nadzor verification; DIRH inspections may require translated documentation. EN ISO 9606 welder qualifications are typically accepted on valid certificate plus continuity log, with the host employer retaining proof.

The EU qualifications-recognition framework is transposed through the Zakon o reguliranim profesijama i priznavanju inozemnih stručnih kvalifikacija (NN 82/2015 with amendments), giving effect to Directive 2005/36/EC as amended by Directive 2013/55/EU. For chamber-regulated engineering roles, recognition is administered by the relevant chamber. For non-regulated craft trades, free movement applies under Article 56 TFEU subject to firm-level licensing and DIRH notification.

  • IT — Qualifica regionale per termoidraulico / frigorista; Accredia patentino F-Gas. https://www.accredia.it/

4. Social Security & Insurance

A1 portable documents are issued by the home-state social-insurance institution under EU Regulation (EC) 883/2004 and accepted by Croatia authorities for inbound postings. Absence of a valid A1 triggers Croatia social-security liability from day one of work.

Contribution architecture: standard EU host-state pattern of employer + employee contributions on insurable income, typically 25-35% combined depending on trade-specific risk classification and sector-fund supplements where applicable.

Croatian social security operates through three institutionally distinct streams: pension insurance under HZMO (https://www.mirovinsko.hr/) administering Pillar I (generational solidarity) and connecting to mandatory Pillar II individual capitalised accounts at REGOS; public health insurance under HZZO (https://hzzo.hr/); and employment-service contributions under HZZ (https://hzz.hr/). Statutory occupational-injury cover is integrated into HZZO and HZMO rather than operated through a commercial accident insurer.

  • Mirovinsko osiguranje I. stup (Pillar I pension): Zakon o mirovinskom osiguranju (NN 157/2013 with amendments) — total 15.0 % of gross (employee 15.0 %, employer 0 %) [verify 2026].
  • Mirovinsko osiguranje II. stup (Pillar II individual capitalised): Zakon o obveznim mirovinskim fondovima (NN 19/2014 with amendments) — total 5.0 % of gross (employee 5.0 %, employer 0 %), applicable to insured persons born after 1 January 1962 [verify 2026].
  • Zdravstveno osiguranje (health insurance): Zakon o doprinosima (NN 84/2008 with amendments) — total 16.5 % of gross (employer 16.5 %, employee 0 %) [verify 2026 Zakon o doprinosima consolidated text].
  • Zaštita zdravlja na radu / specijalni doprinos (occupational health and safety contribution): historically merged into the 16.5 % zdravstveno rate under the consolidated Zakon o doprinosima reforms — verify any separate add-on lines on the As-At date [verify 2026].
  • Doprinos za zapošljavanje: the standalone employer contribution to active-employment measures was structurally reduced in earlier reforms; verify operative status [verify 2026].

Composite employer contribution (2026): approximately 16.5 % of gross wage (zdravstveno) on the employer side, with the 20.0 % pension burden (15.0 % Pillar I + 5.0 % Pillar II) carried on the employee side as deductions [verify 2026 Zakon o doprinosima]. The Croatian profile is materially lighter on the employer side than the German (Soka-Bau plus standard burden), Austrian (BUAK), or French (CIBTP plus URSSAF) regimes — Croatian deployment cost models should not assume a Western European composite. References: https://www.mirovinsko.hr/ ; https://hzzo.hr/ ; https://www.porezna-uprava.hr/ (administers unified collection through the JOPPD return).

No construction-sector fund equivalent. Unlike Germany (Soka-Bau), Austria (BUAK), Belgium (Constructiv), or France (CIBTP), Croatia operates no statutory sectoral fund for construction-worker holiday pay, weather-idle compensation, or sector severance. Holiday entitlement (godišnji odmor) is administered directly by the employer under Articles 76-86 Zakon o radu at the statutory minimum of four working weeks per year (Article 77). Posted employers face no Croatian-side construction-fund contribution — a material cost difference relative to neighbouring regimes.

5. Wages & Collective Agreements

Croatia statutory minimum wage is set annually by the relevant national authority. Sector-level CBA coverage in construction varies; posted-worker wage parity under Directive 2018/957/EU anchors to statutory minimum or to applicable CBA rates where the agreement has been universally extended.

The Croatian wage architecture combines a statutory Minimalna plaća (minimum wage) under the Zakon o minimalnoj plaći (NN 118/2018, NN 120/2021, NN 156/2022 consolidated at https://narodne-novine.nn.hr/) and the annual Vlada Republike Hrvatske Uredba o visini minimalne plaće setting the operative monthly value, with selective sectoral collective agreements extended under Article 203 Zakon o radu.

  • Minimalna plaća: Annually indexed by Government Decree under Article 6 Zakon o minimalnoj plaći. For 2026: monthly approximately EUR 970-1,000 gross [verify 2026 Uredba o visini minimalne plaće za 2026.]; net approximately EUR 770-790 after employee deductions [verify 2026 Porezna uprava]. Hourly equivalent (derived from 174.67 monthly hours at 40-hour week) is approximately EUR 5.55-5.75 [verify 2026]. The 2022 reform introduced a transparent indexation formula referencing average wage and cost-of-living indices.

  • Sector CBAs in construction — limited extension: The Kolektivni ugovor za graditeljstvo (HUP Udruga poslodavaca graditeljstva / SGH) defines wage tariffs for tariff groups I-IX. Extended-application status under Article 203 Zakon o radu has historically been intermittent — the Odluka o proširenju primjene has been issued, lapsed, and re-issued across cycles. Verify extension status on the deployment date at https://narodne-novine.nn.hr/ — where extended, CBA tariffs apply; where not, only Minimalna plaća binds [verify Odluka 2026].

  • Construction-worker wage levels (2026 indicative): Skilled mason, pipefitter, electrician, and welder gross monthly wages typically range EUR 1,400-2,200 depending on certifications, location (Zagreb / Rijeka / Split premiums 10-20 %), and project type. Average construction-sector gross monthly per DZS Priopcenje 9.1.1 was approximately EUR 1,500-1,650 [verify 2026], rising for industrial-shipbuilding and large-EPC roles. References: https://dzs.gov.hr/ ; https://hup.hr/.

Trade-specific context

HVAC plumber tiering tracks the broader European mechanical-services market with one differentiator: holders of F-Gas Category I command a 20–30% premium over wet-side-only HVAC installers because they can be deployed across the full mechanical scope without a paired refrigeration specialist.

  • Tier 1 (CH, LU, NO, DK) — €23–33 per hour gross for an experienced installer with F-Gas Cat I; CH outliers above €35 in Zurich and Geneva data-centre projects.
  • Tier 2 (DE, NL, FR, BE, AT, FI, SE, IE) — €18–27 per hour gross. IE data-centre corridor (Dublin, Cork) trends to the upper end. NL VRF specialists with STEK background command premium within the band.
  • Tier 3 (IT, ES, PT) — €13–19 per hour gross for the same scope, with frigorista premium in IT roughly +15% over wet-side-only termotecnico.
  • F-Gas Cat I premium — uniform +20–30% across all tiers when the project scope includes refrigerant work, reflecting the regulatory non-substitutability of the certificate.

6. Accommodation & Welfare

Posted-worker accommodation standards in Croatia are governed by general employer health-and-safety obligations under the Labour Code and, where applicable, by sector-specific implementation ordinances setting square-meter-per-worker minima, sanitary-facility ratios, and ventilation/heating requirements. Practical norms on multi-trade sites typically follow national contractor codes of practice.

7. Language Requirements

Croatia’s official administrative language applies to inspectorate notifications, social-insurance filings, and regulatory submissions. Site language fluency expectations follow from the supervisor’s working language and the safety-driven inspectorate posture.

There is no statutory CEFR requirement attaching to the Dozvola za boravak i rad or Plava karta EU at issuance. A Croatian-language requirement applies to the Dugotrajno boravište EU at the level set by Pravilnik [verify 2026], administered through Ministarstvo znanosti i obrazovanja-accredited providers and the Croaticum programme at the University of Zagreb (https://croaticum.ffzg.unizg.hr/). This is a downstream concern for long-staying workers, not an entry barrier.

Croatian (hrvatski jezik) is the principal site language and the canonical language of all DIRH-facing documentation. Site safety briefings, induction, zaštita na radu instructions, and emergency procedures are posted in Croatian under Articles 27-29 Zakon o zaštiti na radu (NN 71/2014 with amendments). DIRH accepts multilingual versions where the workforce is non-Croatian-speaking, but the Croatian version is canonical at every inspection. On tourism, EPC, and shipbuilding sites, English is the engineering language for drawings, ITPs, and method statements; Croatian site induction and Croatian-or-bilingual signage at site entry remain contractually standard.

Practical note: Croatian, Bosnian, Serbian, and Montenegrin retain mutual intelligibility at conversational and site-instruction level. BiH, Serbian, and Montenegrin workers operate without language friction; non-South-Slavic workers (Philippines, Nepal, India, Bangladesh) require structured bilingual induction packs. Indicative 2026 A2 intensive Croatian course cost: EUR 400-900 per term [verify].

8. Compliance & Enforcement

The host-state labour inspectorate conducts site audits with statutory powers under the labour code and posting-regime ordinance. Audit triggers include targeted inspections on high-risk sites, complaint-driven inspections, cross-agency referrals, and routine audits on randomly selected posting notifications.

Common compliance traps cluster around late posting notification, A1 absence, document-translation overhead for non-Latin-script jurisdictions, and CBA wage-parity assumptions where the host-state CBA universal-extension status is variable.

Five recurrent failure modes account for most DIRH, HZMO, and MUP sanctions.

  1. DIRH notification omission (Article 195 Zakon o radu). Failure to file obavijest o upućivanju radnika before work begins, or notification omitting sites or worker identities. Workers rotated across multiple Adriatic or Zagreb sites: each new site / worker requires updated filing; original notification does not carry forward. Post-2018 DIRH consolidation has materially raised coastal-tourism inspection frequency during May-October peak.

  2. Minimalna plaća non-parity and CBA extension misreading. Posted workers paid at home-country rates without verifying gross compensation reaches Croatian Minimalna plaća after conversion and deduction of overseas allowances. Secondary trap: assuming the Kolektivni ugovor za graditeljstvo is currently extended when the Odluka o proširenju primjene has lapsed. Verify extension at https://narodne-novine.nn.hr/ on the deployment date.

  3. HZMO and HZZO contribution evasion. Workers nominally engaged under paušalni obrt / service-contract where the actual relationship is dependent employment under Article 4 Zakon o radu. Reclassification triggers retroactive HZMO Pillar I + Pillar II + HZZO contributions plus interest and Porezna uprava penalties. Third-country invoicing without A1 coverage carries highest exposure.

  4. Permit-scope mismatch. Worker performing tasks materially different from registered Dozvola za boravak i rad scope — permit issued for zidar (mason) but worker deployed as zavarivač (welder) or operater dizalice (crane operator). Permit revocation under the relevant articles of Zakon o strancima. The 2020 reform’s quota removal did not remove role-scope rigour.

  5. Quota-residual exposure on legacy applications. Although NN 133/2020 abolished the prior annual quota and replaced it with a labour-market test, the regime operates deficit-occupation lists and sector exemption lists affecting processing speed. Where the occupation falls outside the current exemption list, the eight-day HZZ labour-market test is mandatory, extending the timeline by 2-3 weeks [verify 2026 Pravilnik o popisu zanimanja u nedostatku].

9. Cost-Per-Worker Breakdown (First Year)

Indicative cost stack for a posted plumber — hvac on a 12-month deployment to a Croatia construction site:

ItemEUR / worker / yearNotes
Gross wage (sector journeyman)35,000Tier-1 wage destination; varies by CBA
Employer social-insurance contributions9,000~25% of gross; varies by jurisdiction

Accommodation (employer-provided, indicative)6,000EUR 500/month; varies by location
Total deployment cost~53,500First-year, fully loaded; excludes per-diem and travel

10. Operational Warnings & Red Flags

  • Pre-arrival posting notification is non-negotiable: late notification is treated identically to non-notification under the host-state Posted Workers Directive transposition. Build the notification milestone into the pre-deployment T-2 weeks checkpoint.
  • A1 absence triggers parallel host-state social-security liability: a posted worker without a valid A1 from home state is presumed host-state-affiliated from day one of work, with retroactive contribution liability cumulating monthly.
  • CBA wage-parity verification: confirm the host-state construction CBA’s universal-extension status before pricing the deployment; assumption of universal applicability is a common compliance error.
  • Subcontracting chain liability: where the host state imposes joint and several liability across the subcontracting chain, the principal contractor bears risk for sub-tier wage and contribution compliance.
  • Sector-fund registration (where applicable): SOKA-BAU (Germany), Constructiv (Belgium), CIBTP (France), Cassa Edile (Italy), BUAK (Austria) — verify whether Croatia’s sector-fund regime covers plumber — hvac deployment and pre-register before site arrival.

Trade-specific context

  • F-Gas refrigerant exposure — asphyxiation in confined-space plant rooms during recovery or leak; HFCs are heavier than air and displace oxygen at floor level. EN 378-3 specifies machinery-room ventilation and detection thresholds.
  • Working at height — rooftop AHU and chiller installation; condenser deck work; high-level pipework in plant rooms. Mobile elevating work platforms and harnessing competence are routinely required (PASMA, IPAF, or country equivalents).
  • Brazing torches — silver-brazing copper refrigerant pipework with oxy-acetylene or oxy-propane; risks include burns, hot-work fire ignition, and inhalation of metal fume (cadmium-free filler is now standard but flux fume remains a hazard). EN 13585 covers brazing.
  • Refrigerant flammability — A2L (R32, R1234yf) and A3 (R290 propane, R600a isobutane) refrigerants now dominant under the F-Gas phase-down. Risks include flash-fire on poorly-purged systems and electrical ignition; the 2024 F-Gas recast adds explicit flammability-handling competence requirements.
  • Pressure systems — refrigerant circuit working pressures (R410A up to 42 bar, R32 similar, transcritical R744 above 100 bar) bring the trade into PED 2014/68/EU territory for components and assemblies.
  • PPE baseline — helmet, gloves (cut-resistant for sheet metal, leather for brazing), safety glasses with side shields, FFP3 respirator for brazing fume and confined-space refrigerant work, full-body harness for rooftop scope. Refrigerant gauntlets and face-shield specifically for charging and recovery operations.

11. Compliance Checklist

  • T-2: Pre-posting notification submitted via host-state inspectorate portal; reference number captured
  • T-1: Site-arrival logistics confirmed; sworn-translated documents pack assembled for site retention
  • T-0: Worker arrives on site; A1, employment contract, payslip-template, time-record system available within inspector accessibility window

Monthly during deployment

  • Wage payment effected at minimum wage floor or applicable CBA tariff with statutory premia
  • Time-records updated and retained on site
  • Social-insurance contributions remitted by host-state due date
  • Sector-fund contributions remitted (where applicable)
  • Any change to worker, scope, or duration triggers notification update

Annual / per-event
