The emerging vulnerability of global manufacturing
For decades, globalisation encouraged manufacturers to source components from countries offering the lowest costs, highest efficiency, and greatest technological specialisation. International production networks enabled companies to reduce inventories, achieve economies of scale, and manufacture sophisticated products through geographically dispersed supply chains.
However, the global manufacturing system is confronting a fundamental contradiction: the same international specialisation that improves efficiency can also create dangerous industrial dependencies.
A modern automobile may require thousands of components sourced from multiple countries. Electronics manufacturing depends on semiconductors, precision components, specialised chemicals, and advanced production equipment. Pharmaceutical production relies on active pharmaceutical ingredients, intermediates, and chemical inputs. Renewable energy systems depend on solar wafers, battery materials, power electronics, and critical minerals.
A shortage of one essential input can interrupt production across an entire industrial value chain.
The emerging question is therefore not simply where countries manufacture finished products, but whether they possess reliable access to the critical inputs required to sustain production.
From global efficiency to strategic vulnerability
Historically, international production networks developed around comparative advantage, economies of scale, and industrial specialisation.
East Asian economies became particularly successful in building interconnected manufacturing ecosystems. China developed extensive supplier networks, industrial infrastructure, and production capabilities, while Japan, South Korea, Taiwan, and Southeast Asian economies established complementary technological and manufacturing specialisations.
These networks substantially improved global manufacturing efficiency.
Yet several developments have exposed their vulnerabilities:
* Geopolitical tensions and restrictions on advanced technologies.
* Trade barriers, export controls, and industrial policy competition.
* Pandemic-related disruptions and transportation bottlenecks.
* Concentration of critical minerals and specialised processing capabilities.
* Rising uncertainty surrounding access to strategically important components.
The problem is especially serious where a component is produced by only a few specialised suppliers and cannot be replaced quickly.
A country may possess large assembly capacity without possessing genuine industrial resilience.
Recent evidence: Geopolitics is reshaping supply chains
The supplied account of UNCTAD's October 2026 Trade and Development Report highlights an important structural development: international trade is becoming increasingly sensitive to geopolitical alignment, particularly in strategic and high-technology products.
It also points to an important feature of supply chain diversification in East Asia. Countries benefiting from shifts in manufacturing investment may continue to depend heavily on China-centred networks for intermediate goods, machinery, and components.
This suggests that geographical diversification of final assembly does not necessarily produce diversification of the underlying supply chain.
A company may relocate assembly operations from one country to another while continuing to import its most important components from the original manufacturing centre.
Consequently, conventional indicators such as manufacturing investment, export growth, or the number of new factories may exaggerate the extent of genuine supply chain diversification.
The specific UNCTAD findings cited above should be checked against the original report before publication.
The future: From just-in-time production to strategic resilience
Governments and manufacturers are likely to place greater emphasis on industrial resilience alongside cost competitiveness.
Supplier diversification, strategic inventories, component standardisation, alternative sourcing arrangements, and domestic technological capabilities may become increasingly important.
However, building parallel manufacturing capacity is neither simple nor inexpensive.
Semiconductor fabrication, precision engineering, advanced chemical processing, and specialised industrial machinery require substantial investment, skilled workers, technological expertise, and dependable demand.
Duplicating every component domestically would often be economically inefficient.
The objective should therefore not be complete self-sufficiency, but strategic interdependence supported by diversified and technologically capable supplier networks.
Countries will need to distinguish between components that can be imported safely from competitive international suppliers and those whose concentration creates unacceptable industrial risks.
The missing-link challenge in manufacturing
India has significant opportunities as global companies reconsider their manufacturing locations and sourcing strategies.
Its automotive, electronics, pharmaceutical, capital goods, and renewable energy industries provide a substantial foundation for industrial expansion.
However, increasing domestic assembly alone will not necessarily create deeper manufacturing capabilities.
India needs to identify where its industrial value chains remain dependent on imported inputs, particularly components that are technologically sophisticated, difficult to substitute, or supplied by a limited number of countries.
These are priority areas for investigation, not a claim that every listed input is predominantly imported.
Why India's industrial clusters must become central to the solution
India's existing industrial clusters can play a decisive role in developing domestic component capabilities.
Clusters offer advantages that individual enterprises cannot easily create independently: specialised suppliers, shared infrastructure, skilled labour markets, technological services, and opportunities for collaboration.
Yet traditional cluster development programmes have often focused on improving productivity, quality, infrastructure, and market access within existing enterprises.
The next generation of cluster development must go further.
It should systematically identify missing links in industrial value chains and help domestic enterprises enter technologically demanding component markets.
This requires five complementary interventions.
First, value chain dependency mapping. Identify critical imported components, their source countries, supplier concentration, substitution possibilities, and potential production disruptions.
Second, targeted supplier development. Connect capable MSMEs with large manufacturers through long-term procurement commitments, vendor qualification programmes, and technical assistance.
Third, shared technological infrastructure. Establish common testing, calibration, prototyping, certification, and advanced manufacturing facilities.
Fourth, technology partnerships. Encourage collaboration between Indian enterprises, international technology providers, research institutions, and equipment manufacturers.
Fifth, coordinated industrial financing. Provide appropriate risk-sharing mechanisms and long-term finance for component manufacturing projects requiring technological upgrading.
Import substitution should not be pursued indiscriminately. Domestic component production must ultimately achieve competitive quality, productivity, reliability, and cost.
The critical policy question
Can India become a major global manufacturing power if its factories continue to depend on overseas suppliers for strategically important components?
The answer depends on the distinction between expanding manufacturing output and developing manufacturing capability.
Export incentives, production-linked subsidies, industrial corridors, and infrastructure investment can attract manufacturing activity. But sustainable industrial competitiveness requires something deeper: an ecosystem capable of designing, producing, testing, and continuously improving sophisticated components.
This is particularly important for MSMEs, which can become specialised suppliers within domestic and global production networks.
India's industrial policy must therefore move beyond measuring the number of factories established or the value of finished products exported.
It must also measure the technological depth, domestic value addition, supplier diversity, and resilience of its industrial ecosystems.
The next industrial competition will be fought within supply chains
The future of global manufacturing will increasingly be shaped by the ability of economies to combine international integration with strategic industrial capabilities.
Countries that simply attract final assembly operations may gain employment and exports, but remain vulnerable to disruptions elsewhere in the production network.
Countries that develop specialised suppliers, technological expertise, and diversified sourcing systems will be better positioned to sustain industrial growth.
For India, the priority is not to manufacture everything domestically. It is to identify the components that matter most, develop competitive capabilities where economically justified, and integrate Indian MSMEs into sophisticated production networks.
The defining measure of manufacturing strength may no longer be how many finished products a country produces, but how effectively it can sustain production when a critical international supplier becomes unavailable.
And that is why India's next industrial transformation must begin not only in large factories, but also in the specialised supplier networks and industrial clusters that support them.
