Section 711.22 - Duplicative reporting(a)With regard to TSCA section 8(a) rules. Any person subject to the requirements of this part who previously has complied with reporting requirements of a rule under TSCA section 8(a) by submitting the information described in § 711.15 for a chemical substance described in § 711.5 to EPA, and has done so within 1 year of the start of a submission period described in § 711.20 , is not required to report again on the manufacture of that chemical substance at that site during that submission period.(b)With regard to importers. This part requires that only one report be submitted on each import transaction involving a chemical substance described in § 711.5 . When two or more persons are involved in a particular import transaction and each person meets the Agency's definition of "importer" as set forth in 40 CFR 704.3 , they may determine among themselves who should submit the required report; if no report is submitted as required under this part, EPA will hold each such person liable for failure to report.(c)Co-manufactured chemicals. This part requires that only one report per site be submitted on each chemical substance described in § 711.5 . However, both the contracting company and producing company are liable if no report is made. When a company contracts with a producing company to manufacture a chemical substance, and each party meets the definition of "manufacturer" as set forth in § 711.3 , reporting of the co-manufactured chemical can be performed by one of the following methods: (1) The contracting company initiates the required report for that site as the primary submitter. The contracting company must indicate on the report that this is a co-manufacturing situation, notify the producing company, and record the production volume domestically co-manufactured as set forth in § 711.15(b)(3) and processing and use information set forth in § 711.15(b)(4) . Upon notification by the contracting company, the producing company must also record the production volume domestically co-manufactured and complete the rest of the report as prompted by e-CDRweb.(2) Upon written agreement between the contracting company and the producing company, the producing company completes the full report for the co-manufactured chemical. The contracting company supplies the information not otherwise known to or reasonably ascertainable by the producing company. 76 FR 54933 , Sept. 6, 2011, as amended at 85 FR 20148 , Apr. 9, 2020
