What is the US duty on edetic acid from China?
The USITC extract imported on 25 September 2026 does not use the words edetic acid, EDTA acid, edathamil, or tetraacetic. This page does not state a rate for those names.
Ethylenediamine and its salts, HTS 2921.21.00.00, stores 5.8 percent general and 39 percent other.

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.
