What is the US duty on dimethyl ether from China?
The USITC extract imported on 25 September 2026 does not use the words dimethyl ether. This page does not state a rate for that name.
Diethyl ether, HTS 2909.11.00.00, is a different line. It stores 1 percent general and 4 percent other. That is not a dimethyl ether rate. Heading 2909 stores no rate. The anti-dumping file dated 16 May 2026 has no heading 2909 row. 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.
What the extract stores instead
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. A search of the descriptions does not find dimethyl ether. The extract also does not use the words hydrogen bromide, so this page does not state a rate for that name and does not copy the hydrobromic acid line onto it. Confirm the live schedule before you quote. Section 301 stays on the USTR Section 301 page.
| HTS | Description in the file | General rate | Additional duties |
|---|---|---|---|
| 2909 | Ethers, ether-alcohols, ether-phenols, ether-alcohol- phenols, alcohol peroxides, ether peroxides, acetal and hemiacetal peroxides, ketone peroxides (whether or not chemically defined), and their halogenated, sulfonated, nitrated or nitrosated derivatives | blank | blank |
| 2909.11.00.00 | Diethyl ether | 1% | blank |
| 2909.19 | Other | blank | blank |
| 2909.19.14.00 | Methyl tertiary-butyl ether (MTBE) | 5.5% | blank |
The other column is not shown. It does not apply to goods of China.
Diethyl ether stores the unit kg. It has no footnote. Its special-rate text is Free (A,AU,BH,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG). That text does not name China. None of that makes 1 percent a dimethyl ether rate. MTBE is also a different name. HTS 2909.19 stores no rate. The suffix lines described only as Other are not dimethyl ether, and this page does not assign them to that name. The same seller list names carbon tetrachloride beside dimethyl ether. That is a different product. The answer is on US duty on carbon tetrachloride from China.
Dimethyl sulfide (DMS), HTS 2930.90.92.40, is a different description. The general rate and the other rate on that line are blank. This page does not read a blank as Free or as zero, and it does not treat that line as dimethyl ether.
The anti-dumping file, updated_at 2026-05-16T23:32:23.566Z, has no heading 2909 row. That gap is not a finding that no order exists. Check ACCESS before you treat it as a clearance.
A list of codes, three free and up to 50 on Pro, is on the China duty list. Subscribe for the longer list and the copyable report. A rate there is shown only when the file stores it.
Frequently asked
What is the US duty on dimethyl ether from China?
The USITC extract imported on 25 September 2026 does not use the words dimethyl ether. This page does not state a rate for that name. It does not copy another ether line onto it. Heading 2909 stores no rate. The anti-dumping file has no heading 2909 row. Additional duties are not stored for a line the file does not have, so this page does not add a Section 301 percent.
Is diethyl ether the same rate?
No. Diethyl ether, HTS 2909.11.00.00, stores a general rate of 1 percent and an other rate of 4 percent. That line is not dimethyl ether. This page does not treat 1 percent as a dimethyl ether rate, and it does not treat 1 percent as a China total.
Is MTBE the same line?
No. Methyl tertiary-butyl ether, HTS 2909.19.14.00, stores 5.5 percent general and 37 percent other. The lines under HTS 2909.19 that are described only as Other are not dimethyl ether. This page does not assign those lines to that name.
Does dimethyl sulfide fill the gap?
No. Dimethyl sulfide (DMS), HTS 2930.90.92.40, is a different description. That line stores no rate. A blank is not a Free rate and not a zero. It is not dimethyl ether.
