Commerce Fixes Math in China Carbon Duty Review
Published Date: 6/2/2026
Notice
Summary
The U.S. Department of Commerce fixed some small math mistakes in the review of antidumping duties on activated carbon from China for April 2023 to March 2024. This update affects companies like Calgon Carbon, Norit Americas, and Chinese exporters Datong Juqiang and Ningxia Huahui. The corrected results, effective June 2, 2026, could change the money these companies owe or get back.
Analyzed Economic Effects
5 provisions identified: 2 benefits, 3 costs, 0 mixed.
Importers Must Certify Reimbursement or Risk Double Duties
Importers are reminded they must file a certificate regarding reimbursement of antidumping duties prior to liquidation of entries for this review period under 19 CFR 351.402(f)(2). If an importer fails to file the certificate, Commerce may presume reimbursement occurred and assess double antidumping duties.
Ningxia Huahui Duty Cut to $0.04/kg
Commerce corrected math errors and changed Ningxia Huahui's final dumping margin from $0.56 per kilogram to $0.04 per kilogram for the period April 1, 2023 through March 31, 2024. Commerce also revised the rate assigned to non‑individually examined separate‑rate companies from $0.56/kg to $0.04/kg, which can lower the antidumping duties importers owe for affected shipments.
Cash Deposit Rules and China‑Wide Rate Set
Effective on publication, amended cash deposit requirements apply: for DJAC, Ningxia Huahui, and other companies not individually examined the deposit rate equals the amended weighted‑average dumping margin; if a rate is less than 0.50 percent it is de minimis and the cash deposit will be zero. For Chinese exporters not found entitled to a separate rate, the China‑wide cash deposit rate is 2.42 USD per kilogram.
Datong Juqiang Margin Remains Zero
Commerce found that Datong Juqiang Activated Carbon Co., Ltd.'s final dumping margin remains $0.00 per kilogram for April 1, 2023 through March 31, 2024. Entries subject to a zero or de minimis rate may be liquidated without regard to antidumping duties.
Assessment, Liquidation Timing, and China‑Wide Liquidation Rule
Commerce will instruct U.S. Customs and Border Protection to assess antidumping duties based on these amended final results; it intends to issue assessment instructions no earlier than 35 days after publication and may direct CBP not to liquidate entries if a timely summons is filed (up to the 90‑day statutory injunction window). Entries not reported in the U.S. sales database by exporters individually examined in this review will be liquidated at the China‑wide rate.
