Purpose - Korea became a trillion-dollar trading country in 2011. With the exponential increase in Korea's trade volume over the past decades, trade-related administrative burdens per capita for Korea Customs became enormous, for which the government established the Single Window, a trade-facilitating system, in 2004 to enhance the efficiency of customs-clearing procedures for traders. This paper focuses on finding whether the Korean Single Window system affects the country's trade facilitation positively through an empirical methodology. Design/methodology - To find empirical evidence that Single Window affects trade facilitation for the customs-clearing procedure, this study assumes that a time-efficient environment enables the handling of the increase in trade volume, under which four independent variables related to import customs-clearing procedures and two dependent variables to import were adopted for empirical analysis. The import customs procedures are classified into four steps from port entry to declaration acceptance. To understand the relationship between variables, scattered plots and correlation coefficients were calculated. Eight hypotheses were set and underwent simple linear regression. The data for analysis were collected by Korea Customs, and were about the lead time of import, the volume of imports in million USD, and the number of import declarations reported to customs offices on a monthly basis from 2005 to 2013. Findings - Six of the eight hypotheses showed the statistically significant result that lead time in the import customs-clearing procedure positively affects the number of import declaration reports and import volume. Specifically, Hypothesis 1, Hypothesis 2, and Hypothesis 3 strongly support the assumption lead time in import customs declaration has an inverse relationship with the number of import declarations, which means that the shorter the import lead time, the more import declaration increases. Research Limitations/Implications - With limited data accessibility to the government's custom-sclearing procedures, only the import lead time for customs clearance were adopted as independent variables. This paper, however, successfully found that the Single Window system contributed to trade facilitation. Originality/value - This study found that the time-saving Single Window system of Korea Customs enables itself to manage an exponentially-increasing trade volume by creating a trade-facilitating environment for customs personnel and traders, which may be a unique implication found through quantitative methodology.

General Administrative Procedures of the Preshipment Inspection 1. Initial notification Preshipment Inspection is initiated by Agency when it receives notice either from the importing country, or the seller, that an export needs to be imspected 1.1 Notice from the importing country 1.2 Notice from the seller 2. Preliminary price verification After receipt of initial notification, Agency undertakes, Where possible, a preliminary price verification, based upon the Inspection Order and other contractual documents received. 3. Customs classification When required by the Government of the importing country. Agency forms an opinion of the Customs Classification Code based upon the Customs Tariff Book and Rules of Classification of the country of importation. The Customs Classification Code determines the tariff rate on the basis of which the importer will be required to pay import duties. 4. Import eligibility 5. Arrangements for physical inspection 5.1 Inspection request from seller 5.2 Place of inspection 5.3 Date of inspection 5.4 Physical inspection procedures 6. Physical inspection results When the physical inspection is completed, the inspector submits his report to the Agency office and the result of inspection will be communicated to the seller and, where applicable, the place of inspection. The result will state: satisfactory or conditional of unsatisfactory. The seller is welcome to present his views in writting to Agency in the event there is any query regarding the issuance of a conditional of unsatisfactory inspection result. 6.1 Satisfactory 6.2 Conditional 6.3 Unsatisfactory 7. Shipment of the goods The seller is advised to check with Agency prior to shipment if the physical inspection result has not been received or there are any doubts concerning whether a Clean Report of Findings will be issued. 8. Final price verification and classification Based on the results of physical inspection and appropriate final documents, Agency finalises the price verification and the Agency opinion of Customs classification code. When the preliminary price verification has not resulted in any unresolved questions and the inspection result and other documents received are consistent with the preliminary documentation, Agency will not normally require any additional information. The main exception would be if the terms of sale require reference to prices at the date of shipment. 9. The Report of Findings 9.1 Types of Reports of Findings - Clean Reports of Findings(CRF) The Agency will issue a Clean Reports of Findings(CRF), or equivalent document, normally within two working days after receipt of the necessary correct final documents and a satisfactory result in all aspects of the inspection. - Discrepancy Report.

FTA 협정에 따른 특혜관세 적용은 FTA 역외국과 비교하여 상대적 관세인하 효과로 나타나고 이는 회원국 간 수출입 규모의 증가로 이어진다. FTA 관세 제도의 안정적인 활용을 위해서는 무엇보다 관세 당국의 교역 대상 상품에 대한 명확한 원산지 적용 및 적격 여부 판단이 전제되어야 한다. 본 연구는 관세청, 조세심판원 등 관세 당국의 조세행정 집행과정 중에 확인되는 결정문을 바탕으로 원산지검증 제도에 따른 불복청구 절차를 분석하였고, 이를 통해 과세전적부심사청구 불채택 건에 대한 재심청구 비율이 아시아 국가와 서구 사회에서 어떻게 다르게 나타나며, 쟁점 사항이나 검증당사자에 따라 재심청구 빈도나 기각률이 또한 어떻게 다른지에 대한 실증 분석을 실시하였다. 더불어, FTA 국가 간 원산지검증 불복 사례의 희소성 문제를 극복하기 위해 부트스트랩 기법을 활용하여 정량적 분석을 실시하였다. 본 논문의 시사점을 요약하면, 첫째, 서구와의 국제거래가 더 높은 재심청구율을 보인다는 가설을 검정하였고, 둘째, 원산지기준 충족 여부, 직접운송 여부, 인증수출자 여부, 품목분류 적정 여부가 핵심 쟁점 요인으로써 재심사 요구와 유의한 인과관계가 있음을 보였다. 셋째, 재심사 요구와 검증 그룹 간 유의성은 관계가 없음을 밝혔으며, 마지막으로, 품목분류오류는 기각률에 상당히 유의한 영향을 미쳐 관련 사건의 경우, 재심 청구에도 불구하고 기각이 될 확률이 상당히 높다는 실무적 함의를 도출하였다.

The purpose of this study is to examine the legal standards of agreements on the origin of liability and the relevant laws in Korea, to suggest implications for custom authorities and traders wishing to benefit from preferential tariff via FTA, citing the excluded cases of related FTA preferences (court cases and administrative judgments). In order to examine the provisions related to supporting evidence of the origin of liability in FTA, we examined FTAs agreed between Korea and EU, EFTA, ASEAN, U.S., and India relevant to FTA Special Customs Act, court cases and administrative judgements. If verifying the origin to protect the fair trade order impedes to promote utilizing FTA, solutions will need to be suggested. If FTA preference is exempted due to verifying the origin by the import customs authorities, the importer shall pay the income tax calculated in accordance with the general tax rate. This is because the certificate of origin confirmed during verification process is different from the actual origin. In most agreements, the exporter (the producer) shall issue the certificate of origin and since the importer has no other option than obtaining the certificate of origin from the exporter, it may face consequences such as declined credibility from the custom authorities in addition to being disqualified for FTA preferential, if the certificate of origin received from the exporter has flaws. On the other hand, the exporter cannot help but being punished by the customs authorities due to issuing defective origin certificates, but it doesn't have conventionary liabilities for damages incurred to the importer. As a result, importers are forced to pursue legal proceedings to claim damages to exporters or to give up FTA preference. As FTA is increasingly utilized, the number and amount of origin verification in Korea has continuously been increasing while administrative judgements indicates other FTA exporters doesn't seem to gain any support in utilizing FTA like Korea does. It has been 8 years since full-scale supports in FTA launched and now is the time to introduce more efficient and intensive FTA support system In this regard, it is desirable to conduct comprehensive verification on export Next, an institutions that assures FTA-based exports should be established in order to compensate the importer's damages that may occur from disqualified certificate of origin issued by the exporter.

In recent years, BIM has been applied to many building projects. However, IFC, which is the core technology of data exchange in BIM, has not been used widely. In particular, IFC has almost never been used to represent rebars in RC structures. This is because the lack of understanding and utilization strategy for data model of IFC on rebars. The purpose of this study is to store and manage the data on rebars using IFC at the schematic design stage. For this, we investigated the data to represent rebars for RC members, such as beam, column, wall, and slab at the schematic design stage. And, we analyzed the data model of IFC on rebars at the schematic design stage. Based on these investigation and analysis on data, we proposed the strategy for utilization of the data model of IFC on rebars. Finally, for verification, we generated a sample IFC file to represent the rebars of a simple RC structure according to the proposed strategy and imported the sample IFC file into the software, which we developed for this study. Based on the results of the import, we concluded that the data on rebars can be stored and managed using the proposed strategy for utilization of the data model of IFC on rebars.
