① Answer First: KC Mark Is Mandatory — 0% KFTA Duty, 10% VAT
LED linear lights (HS 9405.40) imported into South Korea require KC Certification (Korea Certification Mark, 통합인증마크) under the Electrical Appliances and Consumer Products Safety Control Act (전기용품 및 생활용품 안전관리법). As of 2026, the previously separate KCs (KC Safety) and KC (KC EMC) marks have been unified into a single KC mark — one certification now covers both safety and electromagnetic compatibility.
Key Numbers at a Glance
| Parameter | Value |
|---|---|
| Mandatory Certification | KC Safety Confirmation (안전확인) for LED luminaires |
| Import Duty (KFTA with COO) | 0% |
| Import Duty (MFN, no FTA) | 8% |
| VAT (부가가치세) | 10% on (CIF + Duty) |
| Testing Labs | KTC, KTL, KTR (KOLAS-accredited) |
| Timeline | 4–8 weeks |
| Cost per Model | KRW 2,000,000–4,000,000 (≈$1,500–$3,000) |
| Responsible Person | Must be Korea-based entity with business registration |
| Energy Label (Gov Procurement) | KEEL (Korean Energy Efficiency Label) required |
Who Needs What: Certification Pathways
| Product Category | Certification Type | Risk Level | Testing | Validity |
|---|---|---|---|---|
| LED drivers, ballasts, power supplies | KC Safety Certification (안전인증) | High | Korea KOLAS lab only | 5 years + annual factory audit |
| LED luminaires, linear lights (220V, >50W) | KC Safety Confirmation (안전확인) | Medium | CB test report accepted | No expiry (model registration) |
| LED accessories, low-voltage (<50V DC) | KC Supplier Conformity (공급자적합성) | Low | Self-testing + KATS filing | Perpetual |
Most commercial LED linear lights fall under KC Safety Confirmation — the middle pathway. This allows manufacturers to leverage existing IEC 60598-1 CB test reports, significantly reducing time and cost.
KEEL: Korean Energy Efficiency Label
The Korean Energy Efficiency Label (에너지소비효율등급) is administered by KEMCO (Korea Energy Management Corporation). While not mandatory for all imports, it is required for government procurement contracts (공공기관 조달) and is increasingly demanded by large Korean construction firms and ESCO projects. LED linear lights must achieve minimum efficacy thresholds (typically ≥100 lm/W for indoor applications) to qualify. Testing is done to KS C 7651 and KS C 7652 standards.
② Korean Standards & Certification Pathways for LED Linear Lights

Certification Pathway Decision Matrix
| Scenario | Pathway | Timeline | Cost (KRW) | Key Requirement |
|---|---|---|---|---|
| New manufacturer, no CB report | Full KC Safety Confirmation via KTC/KTL | 6–8 weeks | 3,500,000–4,000,000 | Submit physical samples to Korean lab |
| Existing CB report (IEC 60598-1) | CB Report Conversion → KC Safety Confirmation | 4–6 weeks | 2,000,000–2,500,000 | CB report from IECEE-recognized lab + Korean national deviations |
| CE-certified with EN 60598-1 report | CE Report Review → Supplemental Testing → KC | 5–7 weeks | 2,500,000–3,500,000 | Gap analysis for Korean national differences; may need partial retesting |
| UL-certified (UL 1598) | Full testing at KTC/KTL | 6–8 weeks | 3,500,000–4,000,000 | UL 1598 is not harmonized with IEC; full retest required |
| Multiple models (family series) | Family certification | +1–2 weeks per variant | +500,000–800,000 per variant | Worst-case model tested; others by similarity declaration |
③ Frequently Asked Questions
Q: KC vs KCs — what's the difference?
As of 2026, they are unified. Previously, KCs (KC Safety) was a separate mark for the safety aspect under the Electrical Appliances Safety Control Act, while KC (KC EMC) covered electromagnetic compatibility under the Radio Waves Act. The Korean government consolidated these into a single integrated KC mark (통합인증마크). One certification now covers both safety and EMC requirements. If you had separate KCs and KC certificates before 2026, check with KATS whether your products need re-registration under the unified system.
Q: Do I need a Korean office to get KC certification?
No, you do not need your own Korean office. However, you must appoint a Korea-based Responsible Person (국내책임자) who holds a valid Korean business registration (사업자등록증). This can be:
- Your Korean importer or distributor
- A specialized KC certification agency (대행기관)
- A third-party compliance service provider
The Responsible Person is the legal entity that interacts with KATS, signs the application, and takes liability for compliance. Fees for this service typically range from KRW 300,000 to KRW 1,000,000 per year depending on the scope.
Q: Can I use CE (EN 60598-1) or UL (UL 1598) test reports directly?
CE reports can be leveraged but not directly accepted. EN 60598-1 test reports from ISO 17025-accredited EU labs can serve as a starting point, but KATS requires a gap analysis for Korean national deviations (K 60598-1 has specific differences from IEC 60598-1). Supplemental testing at a KOLAS lab is almost always needed — expect 2–4 weeks of additional testing.
UL 1598 reports are NOT accepted because UL 1598 (North American standard) is not harmonized with IEC 60598-1. Products with only UL certification must undergo full testing at KTC, KTL, or KTR.
The gold standard is a CB Test Report from an IECEE-recognized CB Testing Laboratory (CBTL). This is the most efficient path — KATS accepts CB reports with minimal additional testing for national deviations.
Q: What about EMC testing? Is it included in KC certification?
Yes, EMC is now included in the unified KC mark. Under the 2026 unified system, KC certification covers both safety and EMC. The applicable EMC standards are:
- KN 15 (CISPR 15) — Conducted and radiated emission limits for lighting equipment
- KN 61547 (IEC 61547) — EMC immunity requirements (surge, ESD, burst, voltage dips)
EMC testing is typically done concurrently with safety testing. If you have an existing CE EMC report (EN 55015 / EN 61547), it can help streamline the process, but KATS requires testing to the Korean national standards (KN series), which have minor deviations from CISPR/EN standards — primarily in frequency range and limits for conducted emissions.
Q: How long does the entire process take and what does it cost?
| Item | Timeline | Cost (KRW) |
|---|---|---|
| Appoint Responsible Person | 1 week | 300,000–1,000,000/yr |
| Prepare documentation + CB report | 1–2 weeks | — (existing reports) |
| KOLAS lab testing (if needed) | 2–4 weeks | 1,500,000–3,000,000 |
| KATS application + document review | 2–3 weeks | 200,000–500,000 |
| KC mark issuance | 1 week | Included |
| Total | 4–8 weeks | 2,000,000–4,000,000 |
Q: Are there any labeling requirements beyond the KC mark?
Yes. The following must appear on the product and packaging in Korean language (한글):
- KC mark + certification number
- Rated voltage, frequency, power consumption
- Manufacturer name + country of origin
- Responsible Person name + contact (Korean entity)
- Manufacturing date or batch number
- KEEL (Energy Efficiency Label) — mandatory for government procurement; recommended for commercial sales

Landed Cost Calculation — Worked Example
Below is a real-world example for a single LED linear light fixture imported from China to South Korea under KFTA (with valid COO):
| Cost Item | Calculation | Amount (KRW) |
|---|---|---|
| FOB Price (ex-factory) | Per unit, Shenzhen | 100,000 |
| Ocean Freight (per unit allocation) | LCL, Shenzhen → Busan | +3,000 |
| Insurance (0.3% of CIF) | 0.3% × 103,000 | +309 |
| CIF Busan | FOB + Freight + Insurance | 103,309 |
| Import Duty (KFTA, 0%) | 0% × 103,309 | 0 |
| Dutiable Value | CIF + Duty | 103,309 |
| VAT (10%) | 10% × 103,309 | +10,331 |
| Customs Brokerage Fee | Per entry (~KRW 150,000 / 50 units) | +3,000 |
| Local Delivery (Busan → Seoul) | Per unit allocation | +1,500 |
| Total Landed Cost (per unit) | ≈118,140 |
Summary: A KRW 100,000 FOB LED linear light lands in Korea at approximately KRW 118,000 — an ~18% markup primarily from VAT (10%) and logistics. Without KFTA COO, the 8% duty would add ~KRW 8,265, pushing the landed cost to ~KRW 126,000.
KFTA Duty Savings Comparison
| Scenario | Duty Rate | Duty (KRW) | VAT (KRW) | Landed Cost (KRW) |
|---|---|---|---|---|
| With KFTA COO | 0% | 0 | 10,331 | ≈118,140 |
| Without FTA (MFN rate) | 8% | 8,265 | 11,157 | ≈126,231 |
| KFTA Savings per Unit | — | — | — | ≈8,091 (6.4%) |
