What Happened

The Ministry of Statistics and Programme Implementation (MoSPI) released a revised Index of Industrial Production (IIP) series with a new base year of 2022-23 (FY23), effective from June 1, 2026.
This is the tenth revision of the all-India IIP; the previous series used a base year of 2011-12.
The revised item basket now covers 463 item groups, including 120 new items added to reflect structural changes in India's industrial economy, compared to 407 items in the old series.
New additions include credit and debit cards (magnetic stripe), CCTV cameras, articles of nonwoven textiles, aircraft and spacecraft parts, stents, and non-veterinary vaccines.
Items dropped from the basket include kerosene, fluorescent tubes and CFLs, sewing machines, printing machinery, and bicycle and light motor vehicle tyres — products whose industrial relevance has diminished.
Coverage has been expanded to include minor minerals, rare earth minerals, gas supply, water supply, sewerage, and waste management for the first time.

Index of Industrial Production (IIP): Concept and Methodology

The IIP is a composite short-term indicator published by MoSPI's National Statistics Office (NSO) that measures changes in the volume of industrial output in a reference month relative to a base year. It covers three broad sectors: Mining, Manufacturing, and Electricity. The index is released monthly, six weeks after the reference month, and is a key input for GDP estimation and monetary policy.

Calculated using the weighted arithmetic mean of quantity relatives — specifically applying the Laspeyres' formula, where weights reflect value added in the base year
Three use-based sub-indices are also published: Basic Goods, Capital Goods, Consumer Durables, Consumer Non-Durables, and Infrastructure/Construction Goods
The IIP is one of the high-frequency indicators used by the RBI's Monetary Policy Committee to assess the state of the industrial economy between quarterly GDP releases
Base year revisions are periodically undertaken to update the item basket, weights, and coverage to reflect structural shifts in the economy

Connection to this news: The shift from a 2011-12 to a 2022-23 base year corrects a persistent measurement problem — the older basket overweighted sunset industries (kerosene, CFLs, sewing machines) while underweighting fast-growing modern sectors (digital payments infrastructure, medical devices, advanced electronics).

Base Year Revision: Why It Matters

A base year is the reference period against which all subsequent changes are measured. In statistical indices, an outdated base year distorts measurements because the weights assigned to different items — derived from value added in the base year — no longer reflect the current structure of the economy. Regular base year updates ensure the index remains a faithful mirror of actual industrial activity.

India has revised the IIP base year multiple times: 1937, 1946, 1951, 1956, 1960, 1970, 1980-81, 1993-94, 2004-05, 2011-12, and now 2022-23
The lag between base years (14 years in this case: 2011-12 to 2022-23) was longer than international best practice, which recommends revisions every 5 years
Base year revision often results in headline IIP numbers being revised upward or downward as the weights of faster-growing sectors are updated
The National Statistical Commission recommends aligning base years across major statistical series (GDP, WPI, CPI, IIP) to ensure consistency

Connection to this news: The 14-year gap since the previous base year revision meant the IIP was significantly misrepresenting India's industrial structure; the 2022-23 revision corrects this by reflecting the post-pandemic, digital-era composition of manufacturing and industrial output.

Structural Changes in India's Industrial Economy Reflected in the Revision

The addition and removal of items in the new IIP series is a direct reflection of India's industrial transformation over the past decade — the rise of digital payment infrastructure, medical devices, defence and aerospace manufacturing, and environmental services, alongside the decline of fossil-fuel-dependent goods and low-skill manufacturing.

Credit and debit cards: Reflects India's digital payments revolution; the volume of card production is now industrially significant following the Jan Dhan-Aadhaar-Mobile (JAM) trinity rollout
Rare earth minerals and minor minerals: Added in recognition of India's critical minerals strategy and the growing domestic demand from EV and electronics manufacturing
Stents and non-veterinary vaccines: Reflects India's emergence as a global pharmaceutical and medical devices manufacturing hub
Kerosene and CFLs removed: Align with the near-elimination of kerosene subsidies under PAHAL and the transition to LED lighting under UJALA, making these products industrially marginal
Sewerage and waste management added: Reflects Swachh Bharat Mission-induced growth in the environmental services and urban infrastructure sector

Connection to this news: Each addition and removal in the basket is a data point about India's industrial priorities — the new IIP will more accurately capture performance in sunrise sectors while not distorting figures with sunset products.

Key Facts & Data

New item basket: 463 item groups (up from 407); includes 120 new items
Key items added: credit/debit cards, CCTV cameras, aircraft parts, stents, non-veterinary vaccines, rare earth minerals, gas supply, water supply, sewerage
Key items removed: kerosene, fluorescent tubes, CFLs, printing machinery, sewing machines, bicycle tyres
The IIP is compiled and published by the National Statistics Office (NSO) under MoSPI, released six weeks after the reference month
IIP uses the Laspeyres' formula with base-year value-added weights across Mining, Manufacturing, and Electricity sectors
