How to Read a Korean Used-Car Auction Grade Sheet Before You Wire a Won
The single document that decides whether your container arrives in Tema holding a clean Sonata or a welded-together write-off is the auction grade sheet (성능점검기록부 plus the auction house’s own inspection map).
If you buy Korean used vehicles for the West African market and you cannot read that sheet, you are not sourcing — you are gambling with someone else’s odometer.
This guide walks through the exact marks used by the three auction systems we source from most — the domestic retail aggregators (the domestic retail aggregators), a Korean auction house, and a manufacturer-run auction house (오토벨) — plus how the retail aggregator the Korean domestic listing market and the export-facing aggregators present the same data to overseas buyers.
Everything below is what we check before a single Korean won leaves an account.
The short version
- Overall grade below 4 on a 1–5 (or A–C / 1–10 depending on house) scale — drops resale value in Lagos by a wide margin and often signals accident history.
- There is no single national scale, and this trips up new exporters constantly.
- Every sheet carries a line drawing of the car from above with single-letter codes on each panel.
- Korean domestic cars are driven hard on short urban cycles, so genuine mileage matters more than the year.
Quick read: the four things that kill a deal
- Overall grade below 4 on a 1–5 (or A–C / 1–10 depending on house) scale — drops resale value in Lagos by a wide margin and often signals accident history.
- An “X” mark on the inspection diagram — means panel replacement or frame welding. “W” or “용접” (yongjeop) means welded. These are structural, not cosmetic.
- A mismatch between the displayed mileage and the 성능점검기록부 (performance check record) — the classic odometer-rollback tell.
- “R” without context — repainted panel. One R is normal wear; four R’s plus an X is a rebuilt accident car wearing makeup.
The grade scale is not standardized — know which house you are reading

There is no single national scale, and this trips up new exporters constantly.
a manufacturer-run auction house / AJ Cell Auction use a numeric 1–5 with letter sub-grades. A “4.5” or “A” is genuinely clean; a “3” usually means a documented accident repair.
a Korean auction house publishes a 1–10 condition score plus a separate exterior/interior letter (A/B/C). A 9–10 with A/A is showroom-grade and priced accordingly.
the domestic retail aggregators and the consumer-facing the Korean domestic listing market listings translate these into a star or percentage display, but the underlying document is still the government-mandated 성능·상태점검기록부 that every Korean dealer must attach. Always ask for that PDF, not the marketing summary.
Operator note: the auction-house grade and the 성능점검기록부 are two different documents. The auction grade reflects sale-day condition; the 성능점검기록부 is the legal inspection. When they disagree, trust the inspection record and walk if the seller won’t produce it.
The inspection diagram: decode the body map

Every sheet carries a line drawing of the car from above with single-letter codes on each panel. The codes you must know:
- X — panel exchanged / replaced (교환). On a structural member (frame rail, radiator support, rear panel) this is an accident car.
- W / 용접 — welded. Frame welding is a hard no for our West African resale channel unless the price reflects it.
- A / 판금 — sheet-metal repair / dent pulled.
- R / 도색 — repainted.
- C / 부식 — corrosion.
- U / 요철 — uneven surface / minor dent.
A car with two R’s on bolt-on panels (a door, a fender) is ordinary. A car with an X on the rear floor panel (리어플로어) or side member has been in a meaningful collision regardless of how shiny it looks in the photos.
Mileage and the rollback tell
Korean domestic cars are driven hard on short urban cycles, so genuine mileage matters more than the year. A 2019 Hyundai Santa Fe (TM) showing 40,000 km when the 성능점검기록부 logged 95,000 km eight months earlier is a rollback — full stop.
Cross-check three things: the dash reading, the 성능점검기록부 history, and the TS (한국교통안전공단) inspection records tied to the VIN. The Korea Transportation Safety Authority logs odometer readings at each mandatory inspection. If the trend line is not monotonic, the odometer has been wound back.
Translating grade into a landed-cost decision
Here is the part most guides skip: the grade only matters relative to your landed cost and target margin. Our working framework for a typical mid-size sedan or compact SUV bound for Tema (Ghana) or Apapa/Lagos (Nigeria):
| Stage | What it covers | Notes |
|---|---|---|
| Auction hammer / the Korean domestic listing market price | KRW purchase | Verify against 3+ comparable listings same model/year/grade |
| Auction + dealer fees | ~3–5% | Higher at Lotte/Glovis closed auctions |
| Inland to Incheon/Pyeongtaek port | Domestic haul + yard | Pyeongtaek is the primary RoRo export port |
| Ocean freight (RoRo or container) | FOB → C&F | C&F Tema and C&F Apapa differ; container suits parts + 1–2 cars |
| Destination duty + clearance | Ghana CEPS / Nigeria Customs | Nigeria’s age cap and Ghana’s penalty on over-10-year vehicles bite hard |
Two Incoterms discipline points we enforce: quote buyers on C&F (CFR) so freight is locked, and never agree FOB without confirming who eats demurrage if the vessel slips. A two-week port delay at Apapa can erase the margin on a clean Grade-4 Kia Sorento.
The operator-grade pain is real and specific: grade inflation near auction close (sellers re-list borderline cars hoping for a distracted bidder), the over-10-year age penalty that quietly reclassifies a profitable Sorento into a loss once Ghana’s CEPS schedule is applied, and demurrage roulette at Apapa where clearance delays are the rule, not the exception.
Pre-wire checklist
Before any Korean won moves, we confirm:
- The 성능·상태점검기록부 PDF exists and the VIN matches the listing.
- No X on any structural panel; total R count is sane for the year.
- Dash mileage agrees with TS inspection history (monotonic, no rollback).
- The Korean domestic listing market/auction price is within range of at least three comparable listings (same model code, year, grade).
- Landed cost (purchase + fees + freight + duty) leaves margin after the destination age penalty is applied.
- Incoterm is C&F with demurrage responsibility named in writing.
A grade sheet is not paperwork to file after the sale. It is the sale. Read it like the car’s confession, because in Korea’s auction system, it usually is.
