IDRISS, the Integrated Development Region in South Selangor, is a state-level strategic region under the First Selangor Plan 2021–2025, spanning 16,369.58 acres with ~RM57.7B GDV and 9 high-impact projects. Here is what it means for industrial buyers, and why NCT Smart Industrial Park is a flagship anchor.
IDRISS (Integrated Development Region in South Selangor) is a master-planned economic region established by the Selangor State Government to consolidate and accelerate development across the state's southern districts. It was formalised as a strategic initiative under the First Selangor Plan 2021–2025, commonly referred to as RS-1 (Rancangan Selangor Pertama).
Rather than a single project, IDRISS is an integrated planning framework: it knits together aerospace, port logistics, industrial parks, tourism, and supporting infrastructure so that investment in one node reinforces the others. The intent is to position South Selangor, already home to Kuala Lumpur International Airport (KLIA), as a globally connected hub for high-value manufacturing and trade.
The "integrated" in the name is the key idea. Instead of letting industrial estates, an airport-city, a deep-sea port and tourism develop in isolation, IDRISS coordinates them so that an aerospace tenant near KLIA, a manufacturer in a managed park, and a logistics operator at Carey Island can all draw on the same road network, utilities, talent pool and policy support. For the state, that coordination is meant to lift the whole region's productivity; for a business, it means the surrounding ecosystem is being built up at the same time as your own site.
IDRISS spans two districts in the south of Selangor: Sepang and Kuala Langat. This is the corridor immediately around and west of KLIA, taking in areas such as Dengkil, Bukit Changgang, Salak Tinggi, and Banting, and reaching out toward Carey Island on the Straits of Malacca. The region's proximity to KLIA/KLIA2, the MEX, ELITE, NKVE, KESAS, and PLUS highways, and the West Coast Expressway (WCE) is central to its logistics appeal.
According to Invest Selangor, the state's investment promotion agency, IDRISS is defined by the following headline numbers. (Where you see larger numbers elsewhere, treat the Invest Selangor figures as the official basis.)
| Metric | Official figure (Invest Selangor) |
|---|---|
| Total area | 16,369.58 acres |
| Estimated gross development value (GDV) | ~RM57.7 billion |
| High-impact projects | 9 |
| Districts covered | Sepang & Kuala Langat |
| State framework | First Selangor Plan 2021–2025 (RS-1) |
Note: A broader ~40,000-acre figure is sometimes cited for the wider South Selangor growth area. That is a different, broader basis. This article uses the official 16,369.58-acre figure attributed to Invest Selangor.
IDRISS gathers several high-impact developments under one regional umbrella. The table below summarises the key anchor projects.
| Anchor project | Primary focus |
|---|---|
| NCT Smart Industrial Park (NSIP) | Smart, low-carbon managed industrial park, flagship industrial anchor |
| Selangor Aero Park | Aerospace manufacturing, MRO and aviation supply chain |
| KLIA Aeropolis | Airport-city: air cargo, logistics, aerospace and MICE around KLIA |
| Carey Island Port / SEZ | Deep-sea port and special economic zone on the Straits of Malacca |
| Sepang Gold Coast | Coastal tourism, hospitality and leisure |
Among these, NCT Smart Industrial Park (NSIP) stands out as the flagship industrial anchor of IDRISS. Developed by NCT Group / NCT Land (parent NCT Alliance Berhad, listed on Bursa Malaysia), NSIP is a leasehold, master-planned Managed Industrial Park (MIP), recognised by the Malaysia Book of Records as Malaysia's first Managed Industrial Park.
NSIP spans roughly 732 acres with an estimated RM10 billion GDV, of which Phase 1 is 230.09 acres. It sits in the Sepang district, with the site straddling Sepang and Kuala Langat along Jalan Langat Lestari. Crucially, it is about 12 km to KLIA / KLIA2 and roughly 5 km to all major highways, exactly the connectivity IDRISS is built around.
What makes NSIP a true "smart" anchor:
On flood resilience, NSIP is engineered to sit above the 100-year flood level, paired with a Blue & Green Force canal flood-mitigation system and a green-belt canal corridor. It also carries strong third-party recognition, including a 5-Diamond rating under the Low Carbon Cities (LCCF) framework from MGTC, which matters for tenants whose own customers expect verifiable ESG credentials in the supply chain.
Looking ahead, NSIP is also positioning for the digital economy: NCT Alliance signed a term sheet in May 2026 to sell a roughly 100-acre parcel for an up-to-800 MW data centre within the park, underlining how the IDRISS region is attracting next-generation infrastructure alongside conventional manufacturing.

As a flagship Selangor initiative, IDRISS is positioned to attract a coordinated package of state-level incentives and facilitation, from investment promotion via Invest Selangor to infrastructure prioritisation and streamlined approvals for high-impact projects. The targeted sectors mirror the region's strengths: semiconductor, electrical & electronics (E&E), smart logistics, data-centre-adjacent activity, IR4.0, and clean light/medium manufacturing.
For an industrial buyer or investor, IDRISS reduces a key risk: uncertainty about long-term direction. When the state government anchors a corridor with a 5-year plan, named high-impact projects, and dedicated promotion, the infrastructure and demand fundamentals are far more predictable. Buying into a flagship anchor like NSIP means buying into:
The most direct route into IDRISS for manufacturers is a managed park unit. NSIP offers factory products from 2-storey semi-detached and cluster factories up to large detached factories, with indicative pricing from RM5,108,000 for entry semi-detached units. Larger corner cluster and detached options scale up from there to suit heavier or higher-throughput operations. Discounts and full unit-by-unit details are best confirmed directly, contact us and we will walk you through current availability.
A practical way to evaluate the region is to start with your operational must-haves, airport proximity, highway and port access, power capacity, ESG credentials and worker-welfare facilities, and then map them against what a managed anchor like NSIP already provides. Because IDRISS is a long-term, state-backed framework rather than a one-off launch, early positioning inside a flagship park can lock in a strategic address before the surrounding ecosystem fully matures.
