Hello, I am a user of KOSIS data. Referring to the IP Volume data table from this site - https://kosis.kr/statHtml/statHtml.do?orgId=101&tblId=DT_1F02012&conn_path=I2&language=en I noticed that two of the series in the table (Fuel Oil export quantity and Sand inventory quantity) are revised to reflect 0 as its value. - Fuel Oil export quantity, from 2021 April to 2021 June and from 2022 January to 2025 January - Sand Inventory quantity from 2022 May to 2025 January Can the team help to check and verify if these 0 values are accurate? Any additional explanation will also be highly appreciated. Thanks so much. Regards, Valerie Ho

Dear Valerie Ho, Thank you for visiting the KOSIS website. In general, the Industrial Production Index may show changes in the past time-series data when statistics are announced in January every year after the revision of weights using the latest data, the reflection of final datasets and the seasonal adjustment. Accordingly, the datasets of the industrial production published in January 2025 showed a change from the past ones owing to annual adjustments as usual. Warm regards, Statistics Korea
