Atlas Legal published detailed commentary on the full financial liability structure arising from smuggling charges under South Korea’s Customs Act — covering the domestic wholesale price surcharge, mandatory fines under the Special Cases Act, and penalty taxes assessed upon criminal conviction.
Scope of the Commentary
This commentary addresses cases prosecuted under Article 269(2) of South Korea’s Customs Act (smuggling) and Article 6 of the Act on Special Cases Concerning the Punishment of Specific Crimes. The analysis covers common fact patterns including misuse of simplified clearance (목록통관), name-splitting schemes, and freight forwarder misprocessing, and reflects current enforcement practice at Incheon Main Customs and Incheon Airport Customs.
The Surcharge: Why the Domestic Wholesale Price Standard Matters
Under Article 282(3) of the Customs Act, when smuggled goods cannot be physically seized, the court must order a surcharge equal to the domestic wholesale price of the goods at the time of the offense. The Supreme Court defines this as the price including import duties, customs clearance costs, and a reasonable profit margin — not the defendant’s actual acquisition cost (Supreme Court, September 21, 2017, 2017Do8611). When smuggling continues over multiple years and all goods have been sold, the surcharge applies to the entire cumulative volume. Prosecutors typically estimate this figure by multiplying the defendant’s declared import cost by a standard factor, which frequently overstates the actual market price and creates a meaningful opportunity for reduction through defense advocacy.
Mandatory Fine Under the Special Cases Act
When a single smuggling incident involves goods valued at KRW 200 million or more, Article 6(6)(2) of the Special Cases Act mandates a fine equal to twice the goods’ value alongside imprisonment — with no judicial discretion to waive it. A defendant who receives a suspended sentence on goods valued at KRW 300 million will nonetheless receive a mandatory fine of KRW 600 million. This threshold is measured per incident, not as the aggregate of multiple shipments. Below KRW 200 million per incident, a concurrent fine is discretionary under Customs Act Article 275.
Penalty Taxes and Co-defendant Surcharge Exposure
Upon criminal conviction under Article 269, a penalty tax of 60% of applicable customs duties is imposed under Article 42(3)(1) of the Customs Act, in addition to the surcharge and any fine. For under-valuation cases, a separate 60% penalty tax on underpaid duties applies under Article 42(2). When multiple defendants are charged together, South Korean courts may impose the full surcharge amount on each co-conspirator independently, consistent with the Supreme Court’s confirmation that customs surcharges serve a punitive function (Supreme Court, April 14, 2006, 2006Do638). If one party pays in full, enforcement against the remaining co-defendants is released.
Surcharge Reduction and Early Defense Engagement
Because Article 282(3) requires the actual domestic wholesale price — not a formula-based estimate — there is frequently a gap between the prosecution’s figure and what can be established through market evidence, distributor records, and formal fact-finding requests. This work is most effective when defense counsel is engaged during the investigation phase, before the indictment locks in the prosecution’s surcharge calculation. Customs violations involving Incheon Port or Incheon Airport are investigated by Incheon Main Customs (인천본부세관), a specialized agency with independent investigative authority. Counsel should be retained before the first investigative interview.
