Waste Infrastructure Construction With a Clear Bali Opening

This activity covers the civil works behind solid, liquid, and gas waste systems, and the record treats it as nationally foreign-open and not blocked in Bali.

The honest national-vs-Bali picture is not a contradiction: nationally it is foreign-open up to 100%, and in Bali the record does not block PMA registration under the moratorium.
What Changed

Direct 1:1 match from KBLI 2020 — code and scope unchanged.

What You Need

Nationally, this field is fully open (100% PMA). In Bali, it's not blocked by the local moratorium, so foreign companies can enter. However, it's flagged as medium-high risk, meaning you'll face stricter location-specific checks—each address needs verification, and environmental permits will be non-negotiable.

Who This Is For

Foreign infrastructure or environmental engineering firms ready to take on complex, highly regulated waste management construction projects.

Common Questions
Can foreigners operate a wastewater treatment civil works business in Indonesia?
Yes. KBLI 42203 (Konstruksi Bangunan Sipil Sistem Pengolahan Limbah) is TERBUKA — open to 100% foreign ownership via PT PMA. No local Indonesian partner required. (Source: Perpres 10/2021 as amended by Perpres 49/2021 — the investment-list annexes predate KBLI 2025; per-code crosswalk audit in progress.)
What license is required for KBLI 42203?
KBLI 42203 has a Menengah Tinggi risk classification. Required license: NIB + Sertifikat Standar. Processing time: 15.
What is KBLI 42203?
KBLI 42203 is the Indonesian business classification code for "Konstruksi Bangunan Sipil Sistem Pengolahan Limbah" (Wastewater Treatment Civil Works). It falls under Section F of KBLI 2025, the Indonesian Standard Industrial Classification updated by BPS (Regulation 7/2025). The June 2026 KBLI 2025 transition window has closed; operators should verify the code's current OSS/NIB treatment before relying on it for licensing, reporting, or amendments.
How did KBLI 42203 change from KBLI 2020 to 2025?
KBLI 42203 was mapped from previous code 42203 (KBLI 2020). This is a direct match — the code number and scope remained the same. The June 2026 KBLI 2025 transition window has closed. If an NIB still relies on legacy KBLI 2020 mappings, treat the migration as overdue and verify/remediate the OSS record before new license applications, amendments, LKPM, import approvals, or investor/worker sponsorship.
