KBLI 42203 is open to PT PMA at the class level under BUPM. Some sub-activities are restricted to Indonesian capital or require partnerships — a foreign investor can operate the unrestricted slices. Confirm with our team to scope the open portion against your business plan.
OSS RBA classifies KBLI 42203 as Medium-High — NIB + Verified Standard Certificate at Large scale. No specific PB UMKU permits recorded against this code. Licensing instruments follow the standard ladder; no sector-regulator override is on file for this code.
Foreign representative offices must form a structured JV with a qualified Indonesian partner (≥30% project cost executed domestically), employ more Indonesian workers than foreign, appoint an Indonesian responsible party, prioritise domestic materials, and provide technology transfer. Not a clean PT PMA setup — every project is structured around the Indonesian partner.
Worth confirming: Openness here is based on BUPM (Pres. Reg. 10/2021). Sector regulators (PSE/Kominfo for digital platforms, BPOM for food and cosmetics, OJK for financial, Kemenkes for healthcare, Permendag for retail, ESDM for energy) often add licensing and capital requirements on top — the practical answer depends on your business model.

Civil Construction of Infrastructure and Facilities for Solid, Liquid, and Gas Waste Treatment Systems.
Last updated · Sourced from OSS Indonesia
This group includes activities related to the construction, maintenance, and/or reconstruction of facilities for the processing of solid, liquid, and gas waste, waste reservoirs, waste piping networks, urban wastewater infrastructure (domestic/human and industrial wastewater collection networks), waste disposal and incineration facilities, and complementary facilities for solid, liquid, and gas waste, final waste disposal sites along with their complementary structures, and services for the installation of septic system construction, as well as the construction of waste treatment units generated from thermal, hydro, geothermal, and other new and renewable energy (EBT) sources.
Operating license routes through Ministry of Public Works (PUPR) / Sector ministries, not OSS — Emerhub handles the application end-to-end.
SBU classification specific to civil works (jalan/jembatan, pengairan, etc.).
Specialised infrastructure (military, defence, airport) typically restricted to highest SBU grades and may require additional sector-ministry approvals.
PBG required project-by-project; environmental clearance (UKL-UPL or AMDAL) for large works.

Indonesia's BUPM (Investment Business Fields) regulation places this code into one of five tracks. The track determines whether a foreign investor (PMA) can operate in this activity at all, and under what conditions.
KBLI 42203 is open as a class — a 100% foreign-owned PT PMA can be incorporated under this code — but Pres. Reg. 10/2021 carves out 1 specific sub-activity that are off-limits or restricted for foreign capital. The rest of the activity remains open to PMA. The carved-out items are listed below; any of them needs to be either avoided, served via an Indonesian operator, or structured around case-by-case.
Emerhub is a corporate-services provider in Indonesia. We do the legal and regulatory legwork for foreign investors so you can focus on the business itself. Here's what the engagement looks like.
We confirm KBLI 42203 is the right primary code for your business, advise on secondary codes you may also need, and finalize the holding structure with you before any filing.
We draft the Articles of Association before a notary, register the entity with the Ministry of Law & Human Rights (Kemenkumham), and obtain the company's tax ID (NPWP). Under BKPM Reg. 5/2025, paid-up capital is IDR 2.5 billion (~USD 160K) — the cash actually deposited at incorporation. The IDR 10 billion+ figure many sources still cite is the total investment commitment per KBLI, realised over time via your LKPM reports.
Specific permits, application requirements and ongoing obligations vary by business scale and the sub-activity within this KBLI. We file these on your behalf — this section is for transparency on what we'll be handling. Switch between scales below; by default we show Large (the PMA scale).

We file the OSS application with KBLI 42203 as your primary business activity, complete the risk-based assessment, and collect the NIB (Business Identification Number) for you — typically within hours of submission. You don't need to touch the OSS portal.
NIB is issued for the preparation stage. To begin commercial operations, the operator must obtain a Sertifikat Standar that has been verified by the competent ministry. The verification step typically requires a site or document inspection. Operating with NIB alone is not legally compliant. We prepare the application bundle, liaise with the competent ministry, and chase issuance through to the certificate. Statutory turnaround: 15 business days — real-world timing typically runs longer when site inspections or additional clarifications are requested.
Post-launch we run your monthly tax filings, quarterly LKPM (Investment Activity Reports), annual general meeting (RUPS), and any sector-specific reporting. You get a single point of contact and a monthly compliance digest — no Indonesian-language paperwork on your desk.
Class-level prerequisites that apply to every operator under this KBLI, independent of business scale. These commonly include minimum capital rules for PMA entities and spatial-planning (KKPR) conformance.
A plain-English explanation of this classification and the businesses it covers.
KBLI 42203 (Civil Construction of Infrastructure and Facilities for Solid, Liquid, and Gas Waste Treatment Systems.) is the 5-digit Indonesian Standard Industrial Classification code for construction of civil infrastructure and facilities for solid, liquid, and gas waste treatment systems. It sits within Construction under the subgroup Construction of Irrigation, Communication, and Waste Networks (major group 42) in the official KBLI 2020 taxonomy maintained by Statistics Indonesia (BPS).
Any Indonesian or foreign-owned entity that intends to operate in construction of civil infrastructure and facilities for solid, liquid, and gas waste treatment systems as a primary or secondary business activity must select this code on its NIB (Business Identification Number). The selected code determines the licensing instruments required, the issuing authority, and the ongoing compliance obligations.
Indonesia's OSS Risk-Based Approach uses the KBLI code to determine three things: (1) whether foreign investment is permitted and at what cap, (2) the risk-based licensing instruments required, and (3) the authority that issues each instrument. Choosing the wrong code can delay or invalidate your license.
Indonesia's BPS published the new KBLI 2025 taxonomy in early 2025. OSS, BKPM and the operating ministries have not yet adopted it — KBLI 2020 remains the active standard for business registration. This is what's coming for this specific code.
KBLI 42203 retains the same code number and scope in the new taxonomy. The activity description, hierarchy, and intended use of the code are preserved.
When OSS adopts KBLI 2025, we'll migrate your existing entity to the appropriate successor code as part of ongoing compliance — no action needed on your end now.
Talk to a specialistIndonesia's OSS Risk-Based Approach assigns a separate risk level for each of the four business scales. The licensing instruments required (NIB, Standard Certificate, Operating License) are determined by the risk level. Foreign-owned entities (PT PMA) must register at the Large scale, so the rightmost column applies to most foreign investors.
KBLI 42203 (Civil Construction of Infrastructure and Facilities for Solid, Liquid, and Gas Waste Treatment Systems.) is the 5-digit Indonesian Standard Industrial Classification code for construction of civil infrastructure and facilities for solid, liquid, and gas waste treatment systems. It sits within the Construction category in the official KBLI 2020 taxonomy maintained by Badan Pusat Statistik (BPS).
KBLI 42203 is open to PT PMA at the class level under BUPM, but Pres. Reg. 10/2021 carves out specific sub-activities that are restricted to Indonesian capital, capped, or reserved for cooperatives/UMKM. A foreign investor can operate the unrestricted slices; sector regulators (BPOM, OJK, Kemenkes, Permendag, ESDM) commonly add their own requirements on top depending on the activity mix. Talk to our team to scope your business plan to the open portion.
KBLI 42203's risk levels per business scale: Micro Medium-High, Small Medium-High, Medium Medium-High, Large Medium-High. Foreign-owned entities (PT PMA) must register at the Large scale.
NIB + verified Standard Certificate (Sertifikat Standar Terverifikasi). KBLI 42203 is Medium-High risk at Large scale, so NIB is issued first, but the Standard Certificate becomes effective only after the issuing ministry verifies compliance (typically through a document review or site audit). Plus one basic requirement (KKPR) at the class level.
BKPM Reg. 5/2025's default floor is IDR 2.5 billion paid-up capital at incorporation + IDR 10 billion+ total investment commitment per KBLI registered (realised over time and reported quarterly via LKPM). Sector regulators (OJK for financial, ESDM for energy, Kemenkes for healthcare, BPOM for food and cosmetics, Permendag for retail, Kominfo for digital platforms) often set higher minimums for specific activities — the binding figure depends on what you actually plan to operate, so confirm with our team before committing capital.
PT PMA setup typically takes 4-8 weeks: AHU registration (1-2 weeks), NIB issuance via OSS (immediate to 1 week), bank account opening (2-4 weeks). The licensing cycle for KBLI 42203 specifically takes 15 days at the Large business scale.
Not on the Tax Holiday or Tax Allowance priority lists. KBLI 42203 businesses pay the standard 22% PPh Badan; Super Tax Deduction (300% R&D / 200% vocational training) may still apply for qualifying expenses.
Authority depends on the investor profile. For PMA: Minister/Head of Agency. For domestic SME scale: typically Governor (for Provincial scope) or Regent/Mayor (Regency/City scope). Specific mapping is in §1 of this page.
Beyond the NIB, no specific auxiliary permits (PB UMKU) are recorded for KBLI 42203. Sector-specific obligations may still apply — verify with the relevant ministry.
KBLIs in the same subgroup 4220: 42201 (Construction of Irrigation and Drainage Networks.); 42202 (Civil Building Construction for Clean Water Treatment); 42204 (Civil Construction of Electrical Buildings.); 42205 (Civil Construction of Telecommunication Buildings for Transportation Infrastructure.); 42206 (Construction of Telecommunication Central Offices.).
