What is the US duty on melamine from China?
The USITC extract imported on 25 September 2026 stores a general rate of 3.5 percent on melamine, HTS 2933.61.00.00. 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 cases A-570-020 and C-570-021 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 other column is not shown. It does not apply to goods of China.
The line has no footnote. The special-rate text does not name China. This page does not treat Free as a China rate, and it does not apply the other rate to a China shipment. Section 301 stays on the USTR Section 301 page.
China cases 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. Both melamine rows set duty_rate_percent to null and set the rate text to "verify per case file on access.trade.gov before invoicing".
| Case | Type | Product in the file | HS tag | Cash-deposit percent |
|---|---|---|---|---|
| A-570-020 | anti-dumping | Melamine | 2933 | not stored |
| C-570-021 | countervailing | Melamine | 2933 | not stored |
Exporting country on both rows 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. Heading 2933 is not proof that every product in the heading is melamine. The same file lists A-570-898, chlorinated isocyanurates, on heading 2933, and that row is a different product with no cash-deposit percent stored. The named tariff line stores no rate. The answer is on US duty on trichloroisocyanuric acid from China.
