What is the US duty on polypropylene from China?
The USITC extract imported on 25 September 2026 stores a general rate of 6.5 percent on polypropylene, HTS 3902.10.00.00. 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 dated 16 May 2026 has no row for heading 3902. 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 heading in the file reads "Polymers of propylene or of other olefins, in primary forms". The unit on both lines below is kg.
| HTS | Description | General rate | Special rate | Additional duties |
|---|---|---|---|---|
| 3902.10.00.00 | Polypropylene | 6.5% | Free (A*,AU,BH,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG) | blank |
| 3902.30.00.00 | Propylene copolymers | 6.5% | 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 polypropylene 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 copolymer 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. Polyisobutylene and polybutylene are different lines. Section 301 stays on the USTR Section 301 page.
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. No row names polypropylene, propylene, or heading 3902. The file therefore stores no cash-deposit percent for this product. Check ACCESS before you treat that gap as a clearance.
Frequently asked
What is the US duty on polypropylene from China?
The USITC extract imported on 25 September 2026 stores a general rate of 6.5 percent on polypropylene, HTS 3902.10.00.00. That is the general rate in the file, not a China total. Additional duties are blank, so this file does not store a Section 301 percent.
Does the 6.5 percent include Section 301?
No. additional_duties on 3902.10.00.00 is blank. Section 301 list membership and the extra percent are not in this file. Read the line on hts.usitc.gov and the USTR Section 301 page before you quote.
Is polypropylene copolymer the same line?
No. Propylene copolymers are HTS 3902.30.00.00. That line also stores a general rate of 6.5 percent, but the other rate is 2.2 cents per kg plus 33.5 percent, and the special-rate text starts with A rather than A*. Additional duties are blank on that line too.
Is there a US anti-dumping case on polypropylene from China in this file?
The anti-dumping file dated 16 May 2026 has 154 entries and no row for polypropylene, propylene, or heading 3902. That is not a finding that no order exists. The cash-deposit rate, if a case covers the shipment, is on ACCESS.
