What is the US duty on soda ash from China?
The USITC extract imported on 25 September 2026 stores a general rate of 1.2 percent on disodium carbonate, HTS 2836.20.00.00. The file does not use the words soda ash on that line. That 1.2 percent is the general rate in the file. It is not a China total.
Additional duties on the line are blank, so this file does not store a Section 301 percent. The anti-dumping file dated 16 May 2026 has no disodium carbonate row and stores no cash-deposit percent for it. This page is the United States file only. It does not state an Australian duty or a ChAFTA percent.

The other column is not shown. It does not apply to goods of China.
The line has one footnote, on the other column: "See 9903.90.08." This extract stops at chapter 39, so heading 9903 is not in the file and no rate from that note is stored. The special-rate text does not name China. This page does not treat Free as a China rate, and it does not apply the 8.5 percent other rate to a China shipment.
HTS 2836.30.00.00 is sodium hydrogencarbonate (sodium bicarbonate) at Free, and it has no footnote. The answer is on US duty on sodium bicarbonate from China. HTS 2836.60.00.00 is barium carbonate at 2.3 percent. Neither line is disodium carbonate. Section 301 stays on the USTR Section 301 page.
Anti-dumping file
Source: the US AD/CVD file, updated_at 2026-05-16T23:32:23.566Z, 154 entries, drawn from the Trade.gov China scope index. No row names disodium carbonate or soda ash. The only heading 2836 row is anti-dumping case A-570-880, product Barium carbonate, exporting country China. That row sets duty_rate_percent to null. It is not a soda ash case. The answer for that product is on US duty on barium carbonate from China. The file therefore stores no cash-deposit percent for disodium carbonate. Check ACCESS before you treat that gap as a clearance.
