What does this Korea product liability insurance calculator do?
Product liability insurance, often shortened to PL insurance, helps a business meet legal liability for bodily injury or third-party property damage caused by a defective product that it manufactured, processed, imported, sold, or supplied.
Korea does not have one universal formula that sets every manufacturer’s limit as a percentage of revenue.
Two businesses with the same sales can face very different maximum losses because the number of users, product batch size, final application, export territory, fire spread, and recall exposure differ.
This tool first builds a maximum credible loss for one occurrence from bodily injury, third-party property damage, defense and dispute cost, and other modeled legal liability.
It then repeats that loss over the selected number of severe occurrences in one policy year, applies the quoted per-claim limit, annual aggregate, and deductible, and shows both the modeled payout and retained exposure.
Finally, it protects the operating reserve you enter and uses the remaining liquidity and annual self-insurance budget to calculate an affordable deductible ceiling and rounded net-limit guide.
Korea-based scope and 2026 boundary
This calculator is based on Korean law and official records checked on July 30, 2026.
It is a planning comparison, not an insurer quote, underwriting decision, coverage opinion, mandatory-insurance determination, or legal assessment of defect and causation.
The actual policy schedule and wording for territory, insured parties, occurrence aggregation, exclusions, defense costs, deductible mechanics, and jurisdiction always control.
The verified Korean legal boundary
The current Product Liability Act record checked through the National Law Information OPEN API has law ID 002039 and MST 193381.
It was promulgated on April 18, 2017 and has been effective since April 19, 2018.
Article 3(1) makes a manufacturer liable for harm to life, body, or property caused by a defective product, but excludes damage occurring only to the product itself.
Article 2 covers manufacturing, design, and warning defects and includes a commercial manufacturer, processor, importer, and a party presenting itself as the manufacturer.
Article 3-2 supplies a rebuttable presumption of defect and causation when the statutory facts are proved.
Article 7 provides a three-year period after the victim knows both the loss and the liable party and, in principle, a ten-year period from product supply, with a special rule for cumulative or latent bodily harm.
Korean product liability exposure categories and treatment in this calculator| Exposure | Legal or policy question | Model treatment |
|---|
| Third-party bodily injury | Actual legal liability for injury, income loss, and damages | Included in basic modeled PL loss |
| Third-party property damage | Damage extending beyond the defective product itself | Included in basic modeled PL loss |
| Defense and dispute cost | Commercial Act Article 720, consent, and inside-or-outside-limit wording | User estimate included in the basic loss |
| Own product and recall | Own-product boundary and separate recall endorsement or policy | Shown separately and excluded from basic payout |
| Punitive or multiplied damages | Article 3(2) conditions, governing law, and insurability | Separate 1x, 2x, or 3x legal stress only |
Three times loss is not automatic
Under Article 3(2), a court may award no more than three times the loss when a manufacturer knew of a defect, failed to take necessary action, and serious bodily harm resulted.
The court considers intent, loss severity, economic benefit, sanctions, duration and scale of supply, financial condition, and remedial effort.
The calculator therefore applies the selected multiplier only to bodily injury as a separate stress uplift and never assumes it is insured.
No universal limit appears in the Act
The full current Product Liability Act contains no universal PL insurance duty, per-claim minimum, annual aggregate, or deductible applying to every business.
A separate product or industry statute, supply contract, tender, customer requirement, or export arrangement may still impose a limit, so confirm those obligations independently.
Liability insurance under the Korean Commercial Act
The current Commercial Act record checked on July 30, 2026 has law ID 001702 and MST 272919, with the current record effective July 23, 2026.
Article 719 states that a liability insurer is responsible when the insured becomes liable to a third party because of an accident during the insurance period.
Article 724(2) allows the injured third party to claim directly against the insurer within the insurance amount, subject to defenses available under the accident and contract.
Defense costs still require wording review
Article 720 includes necessary judicial and extra-judicial defense costs in the object of liability insurance and permits an advance request.
That does not make every legal invoice payable without conditions or decide whether a particular PL wording pays defense cost inside or outside the liability limit.
Enter a credible defense-cost amount here, then confirm consent requirements, panel counsel, allocation, and limit erosion in the actual policy.
How to set each input
Potential injured people and loss per person
Think beyond one sold unit and ask how many users could be affected by the same raw material, production batch, design, software update, or missing warning if the policy treats their claims as one occurrence.
Loss per person is not a statutory fixed amount.
Use claim history, legal review, customer environment, potential treatment, income loss, and settlement experience, then run low, base, and high scenarios rather than pretending one estimate is certain.
Third-party property and defense cost
A battery fire, electrical failure, or industrial component defect can damage a customer’s building, machinery, inventory, or production line far beyond the price of the defective item.
Add credible legal, technical expert, testing, investigation, and settlement expenses.
Keep documentary support for each figure because the calculator does not infer these losses from revenue or product price.
Own-product, withdrawal, and recall cost
Add notice, logistics, sorting, testing, disposal, refund, replacement, and re-manufacturing cost in the separate field.
The Supreme Court decision of March 26, 2015, case 2012Da4824 and precedent ID 177906, held that loss to the product itself and business loss caused by that defect fell within the own-product boundary outside Article 3(1) of the Product Liability Act.
The model adds these amounts to total business exposure but excludes them from the basic PL payout so a recall endorsement or separate recall policy is not silently assumed.
Severe occurrences in one year
A policy can have an adequate per-claim limit and still exhaust its annual aggregate after repeated losses.
Use five-year claim history, batch count, installed sites, units in circulation, and expected recall speed to choose a stress count of similar maximum losses.
This is not an actuarial frequency estimate; it is an aggregate-exhaustion scenario.
Formulas and the net-limit guide
Simplified payout sequence
Bodily injury = injured people × loss per person
Basic PL loss = bodily injury + third-party property + defense + other modeled liability
Per-claim payout = min(max(basic PL loss − deductible, 0), per-claim limit)
Annual payout = min(per-claim payout × occurrence count, annual aggregate)
The model assumes one deductible for each modeled occurrence and treats the quoted per-claim amount as a cap on insurer payment.
It does not reproduce alternate wordings that aggregate a product batch, place expenses outside the limit, apply a deductible to selected damage categories, or use claims-made reporting conditions.
Affordable retention before insurance limit
- Available liquidity equals immediately available funds minus the protected operating reserve, never below zero
- The annual self-insurance budget is divided by the selected severe-occurrence count
- The smallest of available liquidity, budget per occurrence, and basic PL loss is rounded down to KRW 100,000 as the deductible-capacity ceiling
- Basic PL loss minus that affordable retention is rounded up by KRW 10M, 50M, or 100M to form the per-claim net-limit guide
- Annual basic loss minus affordable retention for every modeled occurrence is rounded up in the same way to form the annual aggregate guide
The result is a transparent consequence of your loss and liquidity inputs, not a recommended product from an insurer.
A buyer, tender, overseas jurisdiction, or difficult-to-model tail risk may justify a higher limit than the calculator shows.
Worked Korea PL example
The default example uses three injured people at KRW 50M each, KRW 30M of third-party property damage, and KRW 20M of defense and dispute cost.
Basic PL loss is KRW 200M per occurrence.
A separate KRW 50M own-product and recall exposure makes total business risk KRW 250M per occurrence before any punitive-damages stress.
The quoted policy has a KRW 200M per-claim limit, a KRW 300M annual aggregate, and a KRW 0.5M deductible, with two severe occurrences modeled.
The business has KRW 50M of immediate liquidity, protects KRW 30M for operations, and budgets KRW 10M for annual retained claims.
The selected limit-rounding unit is KRW 100M.
Worked product liability insurance limit and deductible results in Korean won| Result | Amount | Interpretation |
|---|
| Basic PL loss per occurrence | KRW 200,000,000 | KRW 150M bodily + 30M property + 20M defense |
| Current payout per occurrence | KRW 199,500,000 | Basic loss less the KRW 0.5M deductible |
| Current annual payout | KRW 300,000,000 | KRW 399M before aggregate, capped at KRW 300M |
| Affordable deductible ceiling | KRW 5,000,000 | Smaller of KRW 20M available cash and KRW 5M budget per occurrence |
| Modeled per-claim net limit | KRW 200,000,000 | KRW 195M rounded up by KRW 100M |
| Modeled annual net aggregate | KRW 400,000,000 | KRW 390M rounded up by KRW 100M |
| Annual total retained exposure | KRW 200,000,000 | KRW 100M basic shortfall + KRW 100M separate cost |
The current per-claim limit meets the rounded guide, but the annual aggregate is KRW 100M below the modeled aggregate.
The two per-claim payouts would total KRW 399M before the aggregate, so KRW 99M is blocked by the current aggregate; the guide rounds the net annual need of KRW 390M to KRW 400M.
The current policy covers 75% of annual basic PL loss and only 60% of total exposure after separate own-product and recall cost is included.
How to use the result step by step
- Define one occurrence. Read the batch and series wording, then choose the maximum number of affected people and expanded property loss under that occurrence definition
- Separate basic PL from other business cost. Put third-party damage and modeled defense cost in basic loss, and own-product, withdrawal, and recall cost in the separate field
- Run legal stress deliberately. Start at 1x and use 2x or 3x only to inspect a knowing-failure-to-act scenario, never as an automatic award
- Copy the actual quote. Enter the per-claim limit, annual aggregate, deductible, and a severe-occurrence count for aggregate stress
- Protect operating cash. Do not call all bank cash available; retain payroll, rent, material, and emergency reserves before setting a deductible
- Read three gaps separately. A per-claim shortfall, aggregate shortfall, and deductible above capacity require different contract changes
- Request like-for-like quotes. Align territory, insured parties, batch wording, defense-cost treatment, recall cover, and jurisdiction before comparing premium
Practical scenarios by product type
Food and cosmetics
One ingredient or production batch may affect many consumers, making injured-person count and series wording central to the per-claim limit.
Model consumer bodily injury separately from notice, logistics, disposal, refund, and replacement cost.
Electrical products and batteries
Fire can spread into a home, factory, warehouse, machinery, and neighboring inventory, so third-party property exposure may exceed product price many times over.
Include credible fire-cause investigation, technical expert, and litigation cost rather than leaving defense at zero.
Industrial components and OEM supply
A small component can damage a final product or production facility, so identify the final application rather than valuing exposure at component price.
Compare vendor endorsements, additional insured requirements, completed-operations exposure, and contractual-liability exclusions with the supply agreement.
Export manufacturers
Do not copy a domestic KRW limit into an overseas liability decision.
The KBIZ quote questionnaire itself separates domestic and overseas limits and deductibles, so request territory-specific terms for the United States and Canada, Europe, Asia, foreign counsel, local judgments, currency, and vendor coverage.
What the KBIZ quick choices actually mean
The official Korea Federation of SMEs, or KBIZ, PL group-insurance questionnaire offers domestic limit choices of KRW 100M, 200M, 300M, and 500M, plus a custom amount.
It offers per-claim deductible choices of KRW 0.3M, KRW 0.5M, and KRW 1M, plus a custom amount.
The form describes the limit as the amount payable per claim and in total during the one-year insurance period and the deductible as the amount borne by the insured business for a claim.
Quote menu, not law or a market benchmark
These values are quick options from a particular group-policy quote form.
They are not statutory minimums, not a statement that KRW 500M is sufficient, and not an average recommendation for every Korean manufacturer.
KBIZ explains that premium depends on insured products, sales, limit, deductible, insurance history, company and industry claims, export territory, and endorsements, which is why this calculator does not invent a premium rate.
Policy schedule checklist
- Insured products: all products or named products, components, final applications, and new products during the term
- Territory and jurisdiction: domestic Korea, United States and Canada, Europe, Asia, and every actual sales territory
- Trigger: occurrence or claims-made, retroactive date, extended reporting period, and continuity at renewal
- Batch or series: whether many claims from one defect become one occurrence or several deductibles and limits
- Defense cost: inside or outside the limit, prior insurer consent, panel counsel, expert cost, and allocation
- Deductible: per claim, occurrence, victim, or damage category and how often it applies
- Annual aggregate: equal to or above the per-claim limit and whether any reinstatement exists
- Exclusions and endorsements: own product, recall, warranty, performance, pollution, cyber, contractual uplift, and punitive damages
- Insured parties: manufacturer, importer, distributor, installer, vendor, customer, and additional insured requirements
Frequently asked questions
Can revenue alone determine a suitable PL limit?
Revenue is an important exposure and premium-rating input, but it does not directly equal a maximum loss.
User count, batch aggregation, final application, expanded property damage, and jurisdiction can dominate the result, so this tool deliberately avoids a statutory-looking revenue percentage.
Why compare a per-claim limit and annual aggregate separately?
The per-claim limit caps one modeled claim, while the annual aggregate caps all payments during the policy period.
A policy may fund the first accident well and leave a large second accident partly uninsured after aggregate exhaustion.
Is the lowest deductible always best?
A low deductible reduces cash needed after a claim, but premium and small-claim handling can differ.
A high deductible may save premium yet drain working cash after repeated claims, so protect payroll, rent, and supply reserves before deciding what the business can retain.
Does the basic PL limit automatically cover recall cost?
This model says no and places repair, replacement, withdrawal, and disposal in a separate exposure field.
If the actual contract includes product-withdrawal expense or a separate recall policy, compare its trigger, sublimit, deductible, notice requirement, and territory independently.
Does selecting 3x mean the insurer will pay three times loss?
No.
The statutory ceiling is not an automatic award, and insurability of intentional, punitive, or multiplied damages is a separate governing-law and policy issue.
The calculator keeps that uplift outside the basic payout and uses it only as a balance-sheet stress warning.
Why do limitation periods matter for renewal?
Product Liability Act Article 7 uses a three-year knowledge period and, in principle, a ten-year long-stop from product supply, subject to the latent-harm exception.
Claims-made wording, a retroactive date, or a gap at renewal can therefore affect old products still in circulation, so confirm continuity rather than comparing only this year’s price.
