Electronics: The Biggest Export That Earns the Least

The Philippines’ largest export is a processing service dressed as a manufactured good. This story covers what the industry actually does, the economic zone model, value added, competition, the chip supply chain, upgrading, incentive reform and the strategic risk — part of the Philippines Company Stories hub.

What is assembly, test and packaging?

The back end of semiconductor manufacturing: wafers produced elsewhere are cut into individual chips, mounted, wired, encapsulated in packages and tested before shipment to device makers.

It is labour-intensive relative to wafer fabrication, requires clean-room facilities and precise process control, and does not require the enormous capital of a fabrication plant.

That combination is exactly why it located in Southeast Asia: the work needs disciplined labour and reliable operations rather than billions in fab investment.

How does the economic zone model work?

Designated zones offer tax holidays, duty-free import of inputs and equipment, simplified customs and streamlined regulatory processing for export-oriented manufacturers.

Inputs enter without duty, are processed and re-exported, so the zone functions as an enclave that is economically outside the domestic customs territory.

It works: the zones attracted substantial foreign investment and employment. It also limits linkages to the domestic economy, since the enclave buys little locally.

Why is domestic value added so thin?

Because the imported components frequently represent most of the export value, so what the country earns is the processing margin plus wages, utilities and local services.

Gross export figures therefore overstate the contribution substantially, which is a general problem with trade statistics in processing economies.

The meaningful measure is domestic value added in exports, which for Philippine electronics is far below the headline and is the number policy should target.

How competitive is the position?

Reasonably, on labour cost, workforce quality and decades of accumulated process capability, and against Malaysia, Vietnam, Thailand and increasingly Indonesia and India.

Electricity cost is the persistent disadvantage, since clean rooms and test equipment run continuously and Philippine power is the most expensive in the comparison set.

Logistics reliability is the other, since a semiconductor supply chain requires predictable shipment timing that congested ports and airports do not always deliver.

What would upgrading involve?

Moving from assembly and test into design, advanced packaging, testing engineering and eventually wafer-level processes, each requiring more skilled engineers and more capital.

Design services in particular are attractive: high value added, moderate capital, and dependent on engineering talent rather than on power-intensive facilities.

It requires engineering graduate output at scale with the specific skills the industry needs, which returns to the education question that limits every Philippine upgrading ambition.

What did incentive reform change?

Rationalized the incentive regime, replacing indefinite arrangements with defined periods and tying benefits more closely to performance and to activities the government wants to encourage.

Existing investors argued that changing terms retroactively damages credibility, and the treasury argued that open-ended incentives cost revenue without changing behaviour.

Both are partly right, and the practical consequence was a period of uncertainty during which some investment decisions were deferred.

How exposed is the industry to the chip cycle?

Fully. Semiconductor demand is famously cyclical, and assembly and test volumes swing with it, producing employment and export volatility the country absorbs directly.

The pandemic period produced extreme swings, with shortages driving volumes up and the subsequent inventory correction driving them sharply down.

Because the operations are subsidiaries of multinationals, capacity decisions during downturns are made abroad against a global network rather than locally.

What is the geopolitical dimension?

Semiconductor supply chains have become a strategic concern for major economies, driving investment in diversification away from concentrated locations.

That creates opportunity for Southeast Asian assembly and test locations, since companies want capacity outside the most exposed jurisdictions.

Capturing it requires being ready — power, logistics, skilled labour, policy stability — when investment decisions are made, which is a preparation question rather than a marketing one.

What about domestic linkages?

Limited. The enclave model means most inputs are imported, so local suppliers develop slowly and the industry’s multiplier into the domestic economy is smaller than employment figures suggest.

Supplier development programmes attempt to change this, and the constraint is that global electronics supply chains demand quality and reliability standards few local firms meet.

Where linkages have developed, it is usually in packaging materials, precision components and services rather than in the electronic content itself.

Who operates these facilities?

Subsidiaries of American, Japanese, European, Korean and Taiwanese semiconductor and electronics companies, plus contract assembly and test providers serving multiple clients.

Ownership is overwhelmingly foreign, which means the decisions that matter — capacity, investment, technology upgrade — are made in headquarters abroad.

Long-established operations with decades of history in the country are stickier than recent entrants, since accumulated process knowledge and workforce capability are genuine assets.

What is the employment picture?

Substantial direct employment in the zones, concentrated in specific provinces, with the workforce skewed toward technicians and operators alongside a smaller engineering cohort.

Wages are above the national average and below what the same work commands in Malaysia or Singapore, which is the competitive position.

Automation is reducing labour intensity gradually, which means employment growth will lag export growth even if the sector expands.

What is the lesson?

That trade statistics can mislead. An export figure dominated by imported content describes activity rather than earnings, and policy targeted at the headline number targets the wrong thing.

The second lesson is that processing work is mobile. A sector built on incentives and labour cost has no permanent claim on the investment it hosts.

The third is that upgrading is an engineering education problem. Moving from assembly into design requires people the country must train, and no incentive attracts work the workforce cannot perform.

What are the other significant exports?

Vehicle components and wiring harnesses, machinery, chemicals, processed food, garments and mineral products, alongside the dominant electronics category.

Vehicle wiring harnesses in particular are a substantial labour-intensive export where the Philippines holds a meaningful global position.

Services exports — outsourcing above all — are far larger than most merchandise categories and are recorded separately, which is why merchandise trade statistics understate the country’s export performance.

How do trade agreements affect the sector?

Regional agreements reduce tariffs on components moving between Southeast Asian countries, which supports the fragmented supply chains electronics manufacturing depends on.

Information technology agreements have eliminated tariffs on most electronics products among major economies, so the sector operates in a largely duty-free environment.

That means competitiveness is decided by cost, reliability and logistics rather than by trade policy, which is unusual among export sectors.

What is the automation trajectory?

Assembly and test operations are progressively automated, with machine vision, robotic handling and automated test reducing labour content per unit.

That improves the country’s cost position against lower-wage competitors and reduces the employment the sector generates per dollar of output.

It also shifts the skill requirement toward technicians and engineers maintaining equipment rather than operators performing manual tasks.

What would attract advanced packaging investment?

Competitive industrial power, reliable logistics, engineering graduates with the relevant specializations and policy stability sufficient for a decade-long commitment.

Advanced packaging is strategically important because it is where much of the performance gain in modern chips now comes from, which makes it higher value than conventional assembly.

Regional competitors are actively courting exactly this investment, so the window is competitive rather than open indefinitely.

How exposed is the sector to a single customer?

Individual facilities frequently serve one or a few multinational clients, so a client’s product cycle or sourcing decision determines that facility’s volumes entirely.

At the national level the sector is more diversified, with many multinationals operating across several provinces and product categories.

The vulnerability is therefore local rather than national: a plant closure devastates a province while the aggregate export figure barely moves.

What is the workforce profile?

Predominantly technicians and operators with vocational or technical training, supervised by a smaller cohort of engineers, in facilities running continuous shifts.

Retention is generally better than in outsourcing, since the work is day-shift-inclusive, skills are cumulative and career progression into technical roles exists.

Training partnerships between companies and technical schools are common, which is the model the country’s wider upgrading ambition would need to replicate at scale.

What is the outlook for the sector?

Stable to modestly growing, dependent on the global semiconductor cycle and on whether supply chain diversification directs new investment to the country.

Competitive position depends on resolving power cost and logistics reliability, which are the two variables companies cite most consistently.

Without upgrading into higher-value activities, the sector will continue to record large export values and contribute modest domestic earnings, which is the status quo rather than a forecast.

What is the wiring harness industry?

Assembly of the wiring looms that connect a vehicle’s electrical systems, a labour-intensive process performed in economic zones and exported to vehicle manufacturers abroad.

The Philippines holds a meaningful global position in this product, and it faces the same competitive pressures as electronics assembly: labour cost, power and logistics reliability.

Vehicle electrification changes the product substantially, with high-voltage architectures requiring different components and manufacturing processes, which is both risk and opportunity.

How does the sector interact with the peso?

Revenue is dollar-denominated while a portion of costs — labour, utilities, local services — is in pesos, so a weaker currency improves margins for exporters.

That is the opposite exposure from most Philippine businesses, which earn pesos and pay dollars for inputs, and it makes electronics exporters a natural hedge within a diversified economy.

Imported components offset part of the benefit, which is another consequence of the sector’s low domestic value added.
