Key takeaway
1. The starting point: production at home, sales abroad
When a factory in Korea sells its output to a foreign buyer, domestic production and the physical export shipment are closely connected. Even in this simple model, export revenue is not profit. Imported inputs, manufacturing costs, logistics and selling expenses must be paid before a margin remains.
Industries did not all move overseas at the same time or for the same reasons. “Past” in this series identifies the change in business structure; it does not imply one uniform historical sequence for every Korean manufacturer.
2. Overseas production changes the measurement boundary
| Transaction | Useful measure | Do not assume |
|---|---|---|
| Korean-made goods sold abroad | Customs exports and company revenue | All revenue is domestic profit |
| Foreign factory sells locally | Affiliate sales and consolidated results | The entire sale is a Korean customs export |
| Korean components supplied to a foreign affiliate | Component exports and entity-level revenue | Intragroup sales can be added again to consolidated sales |
| Design, maintenance or licensing | The relevant service or usage-fee transaction | Everything belongs in merchandise exports |
| Income from an overseas investment | Investment income, including relevant dividends or reinvested earnings | Income is identical to cash remitted home |
Customs statistics focus on goods crossing an economic territory. Balance-of-payments goods accounting also requires attention to ownership between residents and nonresidents. These boundaries explain why a company’s global footprint cannot be read directly from one export total.
3. Export substitution and new export demand can coexist
Local assembly can reduce shipments of finished products from Korea. A new plant may nevertheless buy Korean machinery, molds, critical parts or consumables. The balance depends on local sourcing, product design, contracts and the stage of plant development.
For an SME, the actionable question is specific: will this customer’s new factory buy our item from Korea, procure it locally, or redesign it out of the process? A bill of materials and supplier-registration requirements are more useful for this decision than a broad headline about overseas investment.
4. Assess the complete cost of producing abroad
Commercial considerations include proximity to customers, delivery times, staffing, logistics, local sourcing requirements and supply-chain resilience. Lower factory costs do not automatically produce a higher total margin. Utilization, quality stabilization, management, inventory and working capital must also be funded.
An internal comparison should assign an owner to every cost. Who handles rejected goods? Who stores spare parts? Who finances the gap between shipment and customer payment? Tariff and origin treatment require separate product- and process-specific verification; a foreign factory address alone does not establish eligibility.
5. A worked example: revenue is not profit
| Illustrative units — not company statistics | Produce in Korea and export | Produce and sell abroad |
|---|---|---|
| External sales | 100 | 100 |
| Manufacturing and procurement | 65 | 58 |
| Logistics, selling and operating costs | 15 | 24 |
| Simplified operating remainder | 20 | 18 |
This is an invented teaching example. Manufacturing costs fall by seven units, but other costs rise by nine. The remainder therefore falls by two. It is not a calculation of net income after tax, financing and accounting adjustments.
Do not add a parent’s component sale to its subsidiary to the subsidiary’s final customer sale when interpreting consolidated revenue without checking eliminations. Likewise, evaluate value retained in Korea through several measures: local procurement, profit, employment, engineering and research. Gross export value and domestic value added answer different questions.
6. Where SME suppliers can enter
| Entry point | Value proposition | Evidence to prepare |
|---|---|---|
| Plant setup | Molds, inspection equipment, automation parts | Specifications, installation schedule, qualifications |
| Recurring production | Critical parts, materials, consumables | Quality record, continuity plan, inventory support |
| Plant operations | Repair, calibration, training, software | Service scope, response time, contracting entity |
| Head-office design and procurement | Approved components and joint development | Technical validation, design fit, cost case |
Our practical recommendation is to draw two separate maps: production locations and purchasing responsibility. Identify who specifies, who contracts, where deliveries go and who pays. This converts an investment announcement into a qualified list of sales targets.
7. Frequently asked questions
Q1. Are overseas affiliate sales Korean exports?
They are not automatically Korean customs exports. Check production, the transaction and physical movement separately.
Q2. Does overseas manufacturing always reduce Korean exports?
No. Finished-goods substitution and demand for Korean inputs can coexist.
Q3. Do higher overseas sales guarantee more profit in Korea?
No. Costs, ownership and accounting treatment also matter.
Q4. Are dividends merchandise exports?
No. Investment income and goods transactions are different categories.
Q5. Does a foreign plant establish a new origin automatically?
No. Actual production and the applicable origin rules must be assessed.
Q6. Can intragroup sales be added to consolidated sales?
Do not double-count them; check consolidation eliminations.
Q7. Must an SME establish its own overseas factory?
No. Direct supply, local partnerships and service contracts are alternative commercial routes.
Q8. What does Part 05 cover?
It separates export growth into price, volume, product and destination effects.
8. Final checklist
| Check | Action |
|---|---|
| Measurement | Separate customs exports, affiliate sales and investment income |
| Production | Map domestic and foreign processes and suppliers |
| Profitability | Compare manufacturing and other operating costs together |
| Domestic value | Check parts, engineering, employment and R&D |
| Sales action | Identify specification, contracting, delivery and payment entities |
