What is the US duty on calcium EDTA from China?
The USITC extract imported on 25 September 2026 does not use the words calcium EDTA, Ca EDTA, chelated calcium, or 23411-34-9. This page does not state a rate for those names.
Calcium carbonate, HTS 2836.50.00.00, stores Free general and 25 percent other. Barium carbonate, HTS 2836.60.00.00, stores 2.3 percent and 8.4 percent. This page does not call either line calcium EDTA, and it does not treat Free as a China total. The extract does not use calcium oxide or calcium sulphate. HTS 2825.90.90.00 is described only as Other and stores 3.7 percent. That number is not copied. Iron oxides store 3.7 percent and are not copied. The sulfate Of iron line stores Free and is not copied. A supplier active-content figure of 10 percent is not a duty. This file does not store a Section 301 percent for a name it does not list. This page is the United States file only. It does not state an Australian duty or a ChAFTA percent.

Shiv Chem Industries, EDTA calcium, prints 10.0 percent, plus or minus 1.0 percent, as active content. It also calls the product calcium EDTA, chelated calcium EDTA, Ca EDTA, ethylene diamine tetra acetic acid calcium, and calcium-disodium complex, and it prints CAS 23411-34-9. The page does not state a date and does not state a US duty. That 10 percent figure is not in this extract. This page does not read it as a duty.
Calcium disodium EDTA is a different missing name. The answer is on US duty on calcium disodium EDTA from China. That page does not use Ca EDTA or 23411-34-9, and it does not state a rate. This page does not add a second rate. Iron EDTA is a different missing name. The answer is on US duty on iron EDTA from China.
