Methods Characteristics
Individual Refund

This is a method of checking the name, specifications, and quantity of the raw materials used in the manufacturing of the
exporting goods and the tax amount initially paid when importing such raw materials individually, and calculating the
refundable amount accordingly. An individual refund is more complicated to prepare than a simplified fixed amount
refund but is more accurate and proper in its refund.

  • Documents to submit: export confirmation document, Certificate of tax payment, and Calculation Bill of Yield Ratio
Simplified Fixed
Amount Refund

This method has been implemented to simplify the refund process in order to encourage the exportation of small and
medium sized companies that do not have the ability to receive individual refund. When calculating (including when issuing
Certificate of Tax Payment on Basic Raw Materials on supplied goods by means of local letters of credit) the refund amount
for small and medium sized companies, with a refund of 600 million won or less in the year to which the refund application
year belongs and a refund of 600 million won or less for each of the latest two years, a certain amount determined by the
government (refer to the simplified fixed amount refund rates table) is considered as the paid tax amount for imported raw
materials for manufacturing exporting goods, and can be refunded.

  • Applicable for small and medium sized companies (a refund of 600 million won or less in the year to which the refund
    application year belongs and a refund of 600 million won or less for each of the latest two years)

to be exported, customs refund can be claimed with supporting documents on such transactions.

A system to certify the tax amount paid, including the import duty
on imported raw materials, after providing the finished products
to the exporter or producers of exported goods (including the
producers of processed raw materials)

A system to certify the tax amount paid – including the import duty on
imported raw materials, after providing the raw materials in the same
condition as they were imported (as they were purchased if they are
produced domestically) – to the exporter or producers of the exporting
goods (including the producers of processed raw materials)
