What is the US duty on barium carbonate from China?
The USITC extract imported on 25 September 2026 stores a general rate of 2.3 percent on barium carbonate, HTS 2836.60.00.00. That 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 lists China case A-570-880 and does not store a cash-deposit percent. This page is the United States file only. It does not state an Australian duty or a ChAFTA percent.

Source: USITC Harmonized Tariff Schedule export, updated_at 2026-09-25T11:27:06.251Z, from hts.usitc.gov exportList chapters 28 to 39. The public schedule is at hts.usitc.gov. The unit on the line is kg. Heading 2836 in the file reads "Carbonates; peroxocarbonates (percarbonates); commercial ammonium carbonate containing ammonium carbamate:". The barium carbonate line has no statistical suffix under it.
| HTS | Description | General rate | Special rate | Additional duties |
|---|---|---|---|---|
| 2836.60.00.00 | Barium carbonate | 2.3% | Free (A,AU,BH,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG) | blank |
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 8.4 percent other rate to a China shipment.
The same heading is not all barium carbonate. HTS 2836.20.00.00 is disodium carbonate at 1.2 percent. HTS 2836.91.00 is lithium carbonates at 3.7 percent, and its suffixes store blank rates. The anti-dumping file has no row for those products. Section 301 stays on the USTR Section 301 page.
China case in the 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. The binding cash-deposit rate is on ACCESS. The barium carbonate row sets duty_rate_percent to null and sets the rate text to "verify per case file on access.trade.gov before invoicing".

Exporting country is China. The manufacturer field reads "All exporters (cooperative-exporter list per case file)". Sunset status reads "five-year-review-cycle". The file does not store an order date or an expiry date. It does not list a countervailing case whose product text is Barium carbonate. That gap is not a finding that no countervailing order exists. This row is the only heading 2836 row in the file. The heading tag is not proof that disodium carbonate or lithium carbonate is the same case.
