JP CSCL — Annual Reporting of Manufacturing and Import Volumes for General Chemical Substances
ENFORCEMENT TIMELINE
Annual mandatory reporting period from April 1 to June 30
Overview
Under Japan's Chemical Substances Control Law (CSCL), this is a post-market management system designed to prevent environmental contamination and health damage caused by chemical substances manufactured or imported domestically. Manufacturers and importers are required to report annually to the national government on the volumes and intended uses of General Chemical Substances, Priority Assessment Chemical Substances, and Monitoring Chemical Substances above certain thresholds, based on the previous fiscal year's activity. The government uses this reported data to estimate environmental releases and to conduct staged safety assessments, including screening evaluations, in order to manage risk.
Enforcement Timeline
April 1 to June 30 each year: Businesses report manufacturing and import volumes and intended uses for the previous fiscal year (April 1 to March 31) to the Ministry of Economy, Trade and Industry, the Ministry of Health, Labour and Welfare, and the Ministry of the Environment, either online or in writing.
Second half of each year: The government conducts screening evaluations based on the submitted data, newly designating or removing substances from the Priority Assessment Chemical Substances category as needed.
From fiscal 2024 onward: As autonomous chemical management is strengthened, businesses are expected to track intended-use information more rigorously and to ensure accurate electronic filing.
Business Impact
Every business that manufactures or imports 1 tonne or more per year of a covered substance (20 kilograms or more for Priority Assessment Chemical Substances, with thresholds varying by category) is subject to the reporting requirement. Companies must fully identify the CAS numbers and constituent substances of raw materials sourced from upstream suppliers and build an internal system to monitor monthly whether these volumes exceed the reporting thresholds, cross-checking against their own customs and manufacturing data.
Reports must also include a use code, which requires businesses to track and confirm how their products are actually used by downstream customers, creating a need for use-tracking practices and coordination with downstream companies through schemes such as chemSHERPA.
Failing to file an annual report, or filing a false report, is a violation of the CSCL subject to penalties, including fines of up to 300,000 yen. Beyond the fine itself, public disclosure of the violating company's name carries a serious risk of reputational damage that can make it difficult to continue business relationships across the supply chain.
