The cashew tree is not native to India. Portuguese traders brought it from Brazil in the sixteenth century, and it found a home along the Malabar coast. But the industrial shelling and peeling of cashew nuts, as a large-scale export trade, took root in Kollam in the twentieth century, using raw nuts shipped from Africa. That paradox, an industry built on imported material and local hands, is the key to understanding both its rise and its current troubles.
Kollam's cashew industry rests on a geographic paradox: the tree grows along the Malabar coast, yet the factories that made the town a global processing centre ran on raw nuts shipped from Africa and Southeast Asia. The Portuguese introduced the cashew from Brazil in the sixteenth century, but the industrial shelling and peeling trade that defined Kollam from the twentieth century depended on imported material. This is the first fact to hold on to: Kollam had the labour and the port, not the plantations. The raw nut arrived by sea, was processed in the town, and left again as kernels for markets in Europe and North America. The town's advantage was organisational, not agricultural.
The reasons for this pattern lie in trade geography. Kollam sits on the coast with a harbour that, in the colonial period, linked it to Indian Ocean networks. When the global cashew trade expanded in the early twentieth century, processors in Kollam could draw on a dense local workforce and established shipping links. Raw nuts came from Portuguese East Africa, later from Tanzania, Mozambique and Kenya, and from Southeast Asian ports. The local supply from Kerala's own cashew trees was never sufficient for the scale of the factories. The industry was, from the start, an import-processing-export operation, and that made it vulnerable to shifts in shipping, tariffs and competition.
That vulnerability is central to the story. Because the raw material was imported, Kollam's cashew factories were exposed to changes in African production, freight costs and trade policy. When African countries began processing more of their own nuts, or when Vietnam built its own processing capacity, Kollam's position weakened. The town did not control its supply chain. It controlled the shelling and peeling, which are labour-intensive steps, and for decades that was enough. The model worked as long as labour was cheap and plentiful and shipping reliable. Once those conditions changed, the absence of a local raw nut base became a structural weakness rather than a manageable cost.
For the observer, the lesson is about how industrial districts form. Kollam became a cashew town not because cashews grew there in abundance but because it had a port, a workforce and commercial networks. The same logic explains why the industry contracted: the advantages that mattered in the twentieth century, manual skill and low wages, matter less when mechanisation and rival producers change the economics. The imported nut at the centre of the trade is therefore not a curiosity but the key to the whole story. Any understanding of Kollam's cashew past has to begin with the ships that brought the raw material and the global markets that took the kernels away.
Cashew processing in Kollam began as household work. Women shelled and peeled nuts at home, often as part of a family economy, and sold kernels to traders. This cottage phase was flexible and poorly recorded, which is why the early history is difficult to date precisely. What is clear is that the transition to organised factories accelerated in the early twentieth century, when export demand and the availability of imported raw nuts made larger-scale operations viable. The factory floor replaced the courtyard, and the pace of work came under the control of supervisors rather than the household. The shift was gradual, but it changed the terms of employment for thousands of women.
Colonial trade networks shaped this transition. British and other European firms were involved in the export of cashew kernels, and Indian merchants and processors linked to those networks built the first substantial factories. The port at Kollam and the railway connections that followed made it possible to move raw nuts in and finished kernels out at volume. The organisational form was not unique to cashew: it followed the pattern of other colonial export industries, where local labour processed imported or locally grown material for distant markets. The difference for Kollam was the sheer concentration of cashew work and the reliance on imported raw nuts, which tied the town's fortunes to shipping schedules and overseas prices.
The factory system brought a division of labour. Shelling, peeling, grading and packing became separate tasks, and the workforce was organised around them. This allowed higher throughput but also made working conditions a matter of public concern. Official committees and labour inquiries in the twentieth century documented the long hours, the repetitive strain and the exposure to dust and heat. The factories were not uniformly grim, but the evidence points to a pattern of strenuous manual work with limited protection. The transition from cottage to factory floor thus meant not only larger scale but also a loss of the autonomy that household workers had, however modest that autonomy may have been.
For anyone trying to read the landscape today, the factory buildings and the port area are the visible residue of this shift. The architecture is utilitarian, and many structures have been adapted or abandoned. The historical record, including government reports and academic studies, is the better guide to what happened inside them. The cottage-to-factory story is also a reminder that industrialisation in Kerala was often built on imported material and exported products, with the region supplying labour and organisation. That model delivered employment for generations, but it left the industry exposed when the global trade changed. The next section turns to the workers themselves, whose experience is the human core of this history.
The cashew factories of Kollam were, and to a large extent remain, workplaces dominated by women. Shelling and peeling were classified as women's work, and the industry drew on a large female labour force from Kollam and the surrounding districts. This was not a matter of choice alone: the tasks were low-paid and considered unskilled, which kept wages down and reinforced the gender division of labour. Women worked in large halls, often seated for long hours, and the pace was set by production targets. The predominance of women is one of the most documented features of the industry, noted in official inquiries and in the records of trade unions and cooperatives.
The labour process itself was arduous. Raw cashew shells contain anacardic acid, a caustic substance that can burn the skin, and the dust from shelling irritated eyes and lungs. Peeling required sharp tools and precise hand movements, repeated thousands of times. Official committees, including labour commissions and factory inspectorate reports, documented these conditions over the decades. The evidence describes long shifts, inadequate ventilation in some units, and a lack of protective equipment. The work was also seasonal and insecure, with periods of intense activity followed by layoffs. These conditions were not unique to Kollam, but the concentration of the industry there made them a defining feature of the town's labour history.
Health and safety were recurrent themes in the official record. Reports noted the risk of dermatitis, respiratory problems and musculoskeletal injuries. The response was slow and uneven. Trade unions and later the cooperative movement pressed for better conditions, and some factories improved ventilation and provided gloves or aprons. But enforcement was difficult, especially in smaller units and in the informal sector, where much of the work took place. The difficulty of measuring informal work means that the full extent of harm is unknown. What the sources can show is that the risks were recognised and documented; what they cannot show is a complete picture of every worker's experience. That gap is important for anyone assessing the industry's human cost.
The predominance of women also shaped the social history of Kollam. Women workers organised, joined unions and became a visible force in the town's public life. Their wages, however modest, supported households and gave them a degree of economic independence. The decline of the industry therefore had consequences beyond employment figures: it eroded a source of income and status for women who had few alternatives. For the observer, the lesson is that the cashew factories were not just economic units but social institutions. Any account that treats the industry only as a trade story misses the gendered labour that made it work. The next section turns to the cooperative and state structures that attempted to sustain it.
By the mid-twentieth century, the cashew industry in Kollam faced chronic problems: fluctuating raw nut supplies, competition, and pressure on wages. The response included state intervention and cooperative organisation. The Kerala State Cashew Development Corporation (KSCDC) was established to support the industry, and the Cashew Workers Apex Industrial Cooperative Society (CAPEX) was formed to bring factories under worker control. These were not minor bodies; they became major employers and shaped the industry's structure in Kerala. Their aims were to stabilise employment, secure raw material and give workers a stake in the enterprises. The results were mixed, and the reasons are instructive.
The KSCDC was set up by the Kerala government to run cashew factories and to procure raw nuts. It aimed to provide steady work and to protect the industry from the volatility of private trade. The corporation operated factories and employed thousands, but it struggled with the same structural problems that affected the private sector: dependence on imported raw nuts, competition from other producers, and the difficulty of modernising while preserving jobs. The cooperative model, represented by CAPEX, sought to place ownership and management in the hands of workers. This was an ambitious attempt to combine employment security with democratic control. It produced a different set of pressures, including the need to balance member interests with commercial viability.
The cooperative and state structures also became part of the political economy of Kollam. They were significant employers, and their fortunes were tied to government policy, trade rules and the global market. When the industry contracted, these bodies faced difficult choices about closures and retrenchment. The sources for their history include government reports, cooperative records and academic studies, which document both the aspirations and the constraints. What they cannot show is a simple verdict on success or failure, because the external pressures were severe. The honest assessment is that the cooperative and state structures delayed but did not reverse the decline. They provided a buffer for workers and a model for public ownership, but they could not change the underlying economics.
For a traveller or observer, the cooperative buildings and the KSCDC facilities are part of the visible landscape, though access is limited and not all are in use. The historical record is the better guide to what these bodies attempted. The lesson is that state and cooperative intervention can shape an industry's social outcomes even when it cannot secure its commercial future. The cashew workers of Kollam gained a measure of organisation and dignity through these structures, and that is a real achievement. But the decline continued, and the next section of this page examines the economic pressures that drove it. The cooperative story is therefore both a model and a cautionary tale about the limits of institutional solutions.
The pressure on Kollam's cashew factories came from several directions at once, and no single cause explains the contraction. Mechanisation is the most cited factor. Automated shelling and peeling lines, developed and adopted in Vietnam and Brazil, reduced the labour content of processing sharply. Kollam's competitive advantage had rested on abundant, low-cost hand labour, particularly the skills of women shellers. When machines could handle a larger share of the kernel without breaking it, that advantage eroded. The shift was gradual rather than sudden, and it operated through investment decisions made far from Kerala, in the equipment and processing firms of competitor countries.
Competition from Vietnam is the second force. Vietnamese production expanded rapidly from the late twentieth century, supported by domestic raw nut supply and by state-backed investment in processing capacity. Vietnam moved from being a minor producer to a leading exporter of cashew kernels, and it did so while Kollam's factories depended on imported raw material. The asymmetry is important: a Vietnamese processor could draw on local farms, while a Kollam processor had to buy nuts on the world market, absorb shipping and handling, and still compete on the sale of the kernel. That structure left little room for error when prices moved.
Changes in global trade compounded these pressures. Trade liberalisation in the 1990s altered the terms on which raw nuts moved and on which kernels were sold. Tariff structures, import rules and the growth of new processing centres in Africa and Southeast Asia shifted the geography of the trade. Kollam's factories also faced domestic constraints: power costs, labour relations, ageing plant and the difficulty of raising capital for modernisation. The Kerala State Cashew Development Corporation and the cooperative sector were intended to shelter workers from the worst of these pressures, but they could not reverse a market shift that was global in scale.
The result has been a long, uneven contraction rather than a clean closure. Some units shut, some reduced shifts, and some continued at low capacity. The honest verdict is that Kollam's cashew industry is now a shadow of its mid-twentieth-century scale, and the reasons are structural, not local. A place that built a global trade on imported nuts and local hands found both sides of that equation changing at once. The factories that remain are a reminder that industrial districts are not permanent, however dominant they once appeared.
The first thing to say about the data is that employment figures for Kollam's cashew industry are unreliable, and the unreliability is not accidental. Official counts have historically captured registered factory workers, while a large share of shelling and peeling has been done informally, in homes and small units, beyond the reach of factory inspectors. The Census of India records workers by category, but the categories do not map neatly onto the casual, seasonal and piece-rate arrangements common in cashew processing. Any figure quoted as a total workforce should therefore be treated as an order of magnitude, not a count.
The difficulty of measuring informal work is compounded by the nature of the labour. Cashew shelling has been organised through contractors, cooperatives and household arrangements, and workers have moved between them. A woman who shells nuts at home for part of the year may appear in no register at all. Official committees and labour commissions have documented conditions and grievances, but their remit has usually been the organised sector. The gap between the registered and the real is the central methodological problem, and it is why estimates of the number of workers displaced by mechanisation vary so widely.
There is also no definitive count of closures. Factories have shut, reopened, changed ownership and changed function, and no single authority publishes a running total. The Kerala State Cashew Development Corporation and the cooperative societies maintain their own records, but these cover their own units, not the private sector as a whole. District-level industrial records exist, yet they are not always current or comparable over time. A traveller or researcher looking for a clean number will not find one, and should be suspicious of any source that offers one without stating its scope.
What the sources can show is the direction of travel and the mechanism of change. They can establish that the industry was once a major employer, that women were the majority of the workforce, that mechanisation and foreign competition are the standard explanations for decline, and that the cooperative and state structures were created in response to chronic instability. What they cannot show, with confidence, is the precise scale of the workforce at any given moment or the exact number of units that have ceased operation. The honest answer is that the record is patchy, and the patchiness is itself part of the story.
Kollam is a port town, and the cashew trade is legible in its geography before it is legible in any document. The port and the backwater system that links it to the interior are the reason raw nuts could be landed and moved. The railway, operated by Indian Railways, tied the town into the wider network that carried kernels to markets. A traveller reading the landscape should start with these connections, because they explain why processing concentrated here rather than somewhere with more cashew trees. The town's position, not its hinterland, was the original advantage.
The factory buildings themselves are the second layer. Many are large, older structures, and some stand in states of partial use or disuse. This page does not print addresses, opening hours or access rules, and it does not name individual units, because those details change and because many are working premises. What can be said is that the architecture of the cashew trade, the sheds, the yards and the workers' quarters, is part of the town's fabric. The Kerala State Archaeology Department and the local body are the authorities for any monument or civic matter, and enquiries about specific buildings belong with them.
The third layer is social rather than physical. The neighbourhoods associated with cashew work carry the imprint of a female workforce: the patterns of settlement, the small shops, the routes workers took. None of this is signposted, and none of it can be read from a distance with confidence. A traveller who wants to understand the industry should read the official reports and the labour history first, then use the town to see the scale of what was built. The landscape confirms the history; it does not explain it on its own.
The verdict for the observer is that Kollam repays a certain kind of attention. It is not a heritage site with a ticket counter and a leaflet. It is a working town whose main industry has contracted, and the evidence is in the port, the railway, the factory shells and the residential quarters. Go with the history in hand and the expectation of fragments, not a museum. The figure that moves most is the state of individual buildings, and the authority for that is the local body and the owners.
Kollam's cashew story matters because it complicates the standard account of Kerala's development. The state is often described through its high human development indicators, its remittance economy and its service sector. The cashew industry is a reminder that Kerala also had a large, difficult, industrial working class, concentrated in a few towns, and that this workforce was overwhelmingly female. The industry's rise and contraction are therefore part of the state's social history, not a footnote to it. Understanding Kollam means understanding that Kerala's prosperity was built partly on export processing of an imported commodity.
The second lesson is about vulnerability. An industry that depends on imported raw material and exported finished goods is exposed to forces it does not control: shipping costs, exchange rates, foreign investment decisions and the industrial policy of competitor states. Kollam's factories had skills, institutions and a trained workforce, and these were not enough. The cooperative and state structures cushioned the shock for some workers, but they could not alter the underlying economics. For a region-scale travel site, the point is that places are shaped by trade geographies that are invisible on the ground.
The third lesson concerns how such a story should be told. The temptation is to narrate decline as tragedy, with the factories as ruins and the workers as victims. The record supports something more measured: a long, contested adjustment, with organised resistance, institutional innovation and real losses. This page does not print prices, opening hours or employment totals, because those figures move and because the sources are patchy. What can be stated plainly is that the industry contracted, that the causes are structural, and that the people who worked in it built something that outlasted the trade.
The verdict for the observer is therefore double. Kollam is worth attention as a case study in how a global industry settles into a place and then leaves it, and it is worth attention as a place in its own right, with a port, a railway, a backwater system and a working town around them. It does not suit a traveller looking for a curated industrial heritage experience. It suits a traveller willing to read first and look second, and to accept that the most important evidence is in documents, not in signage. That is the honest position, and it is the one this page takes.
Why did the cashew industry develop in Kollam rather than elsewhere in Kerala?
Kollam's port allowed the import of raw cashew nuts from Africa and the export of processed kernels. The district also had a large labour force, particularly women, who were skilled in the manual tasks of shelling and peeling. These factors made it the natural centre for the industry.
Are the cashew factories still operating today?
Many factories have closed, but some remain operational under the Kerala State Cashew Development Corporation and cooperative societies. The industry has shrunk significantly due to competition from other countries and mechanisation. The exact number of functioning factories fluctuates and is not reliably published.
What is the role of women in the cashew industry?
Women have historically formed the majority of the workforce in shelling and peeling, tasks that are labour-intensive and often low-paid. Their participation was central to the industry's growth. Official reports have documented the health hazards they face, such as skin irritation from cashew shell oil.
Can visitors see the cashew factories in Kollam?
Most factories are not open to the public, and this page does not recommend attempting to visit without permission. The industrial area and the port can be seen from outside, but the processing floors are workplaces, not tourist sites. The historical context is best understood through the sources cited here.
This page draws on published reports from the Kerala State Cashew Development Corporation, the Cashew Workers Apex Industrial Cooperative Society and the Department of Industries, which document the number of factories and workers over time.
Economic histories of Kerala, including studies from the Centre for Development Studies, provide analysis of the industry's rise and decline, though they note that employment figures are often incomplete.
The exact number of workers and factories at any given time is not measurable with precision because much of the work is informal and unregistered, and records are not consistently maintained.
No business, factory or cooperative paid to appear on this page. The information is compiled from public sources and official reports.
