What is the US duty on ethylene oxide from China?
The USITC extract imported on 25 September 2026 stores a general rate of 5.5 percent on HTS 2910.10.00.00, described as Oxirane (Ethylene oxide). The other rate on that line is 49 percent. The special-rate text does not name China.
The unit is kg. There is no footnote on that line. Heading 2910 stores no rate. Additional duties on the ethylene oxide line are blank, so this file does not store a Section 301 percent. The anti-dumping file dated 16 May 2026 has no heading 2910 row. 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. HTS 2910.10.00.00 stores the unit kg. It has no statistical suffix. There is no footnote. The 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. The extract 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.
| HTS | Description | General rate | Additional duties |

| 2910 | Epoxides, epoxyalcohols, epoxyphenols and epoxyethers, with a three-membered ring, and their halogenated, sulfonated, nitrated or nitrosated derivatives | blank | blank |
| 2910.10.00.00 | Oxirane (Ethylene oxide) | 5.5% | blank |

The heading stores no rate. HTS 2910.90, described as Other, also stores no rate. Propylene oxide stores 55 percent other, not 49 percent. Epichlorohydrin stores 3.7 percent, not 5.5 percent. Its special-rate text includes K. The ethylene oxide special-rate text does not. Butylene oxide stores 4.6 percent and 46 percent, and its special-rate text includes K. HTS 2910.90.20.00, described only as Aromatic, stores 5.5 percent general and an other rate of 15.4¢/kg + 40%. This page does not treat that line as ethylene oxide, and it does not turn the compound rate into dollars. This page does not treat 5.5 percent as a China total. Confirm the line on hts.usitc.gov before you quote. Section 301 stays on the USTR Section 301 page.
Ethylene glycol is not this line. HTS 2905.31.00.00 stores 5.5 percent general and 63 percent other. The answer is on US duty on ethylene glycol from China.
The anti-dumping file, updated_at 2026-05-16T23:32:23.566Z, has no heading 2910 row. That gap is not a finding that no order exists. Check ACCESS before you treat it as a clearance.
