What is the US duty on glycine from China?
The USITC extract imported on 25 September 2026 stores a general rate of 4.2 percent on glycine (aminoacetic acid), HTS 2922.49.43.00. 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-570-836 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.

The unit on the line is kg. The line has no footnote. Heading 2922 in the file reads "Oxygen-function amino-compounds:". The line 2922.49 is described only as "Other:". The file does not store a parent phrase between that line and 2922.49.43.00.
| HTS | Description | General rate | Special rate | Additional duties |
|---|---|---|---|---|
| 2922.49.43.00 | Glycine (Aminoacetic acid) | 4.2% | Free (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 special-rate text does not include A and does not name China. This page does not treat Free as a China rate, and it does not apply the 25 percent other rate to a China shipment. HTS 2922.49.49, other amino acids, also stores a 4.2 percent general rate, but that description is not glycine. Its suffixes 2922.49.49.10 (Alanine), 2922.49.49.15 (l-Aspartic acid), and 2922.49.49.50 (Other) store blank rates. This page does not copy 4.2 percent onto those suffixes. HTS 2922.42.10.00 is monosodium glutamate at 6.5 percent, not glycine.
Section 301 stays on the USTR Section 301 page.

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 glycine 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 Glycine. That gap is not a finding that no countervailing order exists. Heading 2922 is not proof that every product in the heading is glycine. This glycine row is the only heading 2922 row in the file.
