KBLI 03251 requires a mandatory partnership with cooperatives or Indonesian UMKM under Pres. Reg. 10/2021. PT PMA can hold a share of the entity but cannot operate as a standalone foreign-owned business.
OSS RBA classifies KBLI 03251 as Medium-High — NIB + Verified Standard Certificate at Large scale. 1 PB UMKU sector-specific permit apply depending on the exact activity. Licensing instruments follow the standard ladder; no sector-regulator override is on file for this code.
OSS lists 3 operational obligations at Large scale for this code. None are structural foreign-investor barriers, but they determine ongoing compliance: Standard production process for the cultivation of Pisces/brackish water finfish, Business activity report (LKU) and, and others.
Worth confirming: BUPM restricts foreign capital for this activity. Even where a limited path exists (local partnership, SME structuring, alternative KBLI), sector regulators may add their own requirements on top. Talk to our team
Brackish Water Finfish Farming
Last updated · Sourced from OSS Indonesia
This group includes businesses or activities related to the cultivation of brackish water fish (such as milkfish, catfish, tilapia, goldfish, white snapper, and grouper) in brackish water using land, water, and other artificial facilities.
Read the sector notes below carefully before incorporation.
Capture fisheries beyond 12 nautical miles require SIPI/SIKPI permits.
Foreign-flagged vessels are restricted from Indonesian fishing waters.
Aquaculture (KBLI 0321/0322) is more open to PMA, especially seaweed and shrimp farming.
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 03251 is open to investment but the operating entity must form a mandatory partnership with cooperatives or Indonesian UMKM. The structure and terms of the partnership are listed below.
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.
KBLI 03251 requires a mandatory partnership with cooperatives or Indonesian UMKM. We help identify, vet, and contract with qualifying partners — and structure the partnership so it satisfies the regulator without hollowing out your economics.
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).
Documents and capabilities you must demonstrate at registration
Compliance and reporting duties throughout operation
The authority that issues the license depends on your situation.
| Authority | Applies when |
|---|---|
| Regent/Mayor | 1. The business location is within the same district/city and 2. uses simple, semi-intensive, or intensive technology. |
| Minister/Head of Agency | 1. The business location is across provincial borders. 2. It employs foreign workers and/or 3. It uses super-intensive technology. |
| Minister/Head of Agency | Foreign Investment |
| Governor | 1. The business location is across districts/cities within one province and 2. uses simple, semi-intensive, or intensive technology. |
PB UMKU permits sit on top of the main NIB and Sertifikat Standar — each is issued by a different ministry, and only when a specific operational activity is performed. This KBLI carries 1 candidate permit across 1 regulator; most operations only need a handful. Emerhub maps your operation to the exact set, files them, and tracks renewals.
Ministry of Marine Affairs & Fisheries (KKP). Applies to capture fishing, aquaculture, fish processing, fish-feed production, and live-fish trade. The Processing Feasibility Certificate (SKP) is the gating quality permit for fish processors.

We file the OSS application with KBLI 03251 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: 3 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.
A plain-English explanation of this classification and the businesses it covers.
KBLI 03251 (Brackish Water Finfish Farming) is the 5-digit Indonesian Standard Industrial Classification code for brackish water fish farming. It sits within Agriculture, Forestry, and Fisheries under the subgroup Brackish water fish farming. (major group 03) in the official KBLI 2020 taxonomy maintained by Statistics Indonesia (BPS).
Any Indonesian or foreign-owned entity that intends to operate in brackish water fish farming 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 03251 does not carry the same number forward into KBLI 2025 — the activity has been reclassified, but the precise mapping isn't recorded in our database yet.
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 03251 (Brackish Water Finfish Farming) is the 5-digit Indonesian Standard Industrial Classification code for brackish water fish farming. It sits within the Agriculture, Forestry, and Fisheries category in the official KBLI 2020 taxonomy maintained by Badan Pusat Statistik (BPS).
Mandatory partnership with cooperatives or Indonesian UMKM is required under Pres. Reg. 10/2021. Sector regulators may add further licensing requirements depending on the activity — our team structures the partnership and confirms the licensing stack.
KBLI 03251's risk levels per business scale: Micro Medium-Low, Small Medium-Low, 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 03251 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). One sector-specific PB UMKU permit also applies. See the requirements summary at the top of the page.
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 03251 specifically takes 3 days at the Large business scale.
Not on the Tax Holiday or Tax Allowance priority lists. KBLI 03251 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: Regent/Mayor. 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, KBLI 03251 carries 1 PB UMKU permits across 1 sector regulator: Marine & Fisheries (1). Most operations only need 2-4 of these — the relevant set depends on which specific activities you actually perform; Emerhub maps the right subset before filing.
KBLIs in the same subgroup 0325: 03252 (Pembenihan Ikan Air Payau); 03253 (Brackish Water Mollusk Farming); 03254 (Brackish Water Crustacean Farming); 03255 (Brackish Water Aquatic Plant Cultivation); 03259 (Cultivation of Other Brackish Water Organisms). These are closely related activities — see the related-codes section below for full list.
