US tariff heading 5401 covers: “Sewing thread of man-made filaments, whether or not put up for retail sale”. Below is every rated line under it. Each row is a statistical breakout within the heading; which one a shipment falls under is a classification decision, and adjacent lines can carry very different duty.
| HTS | Description | General (MFN, before 301/AD/CVD) | Preferential, where the goods qualify |
|---|---|---|---|
| 5401.10.00.00 | Of synthetic filaments (200) | 11.4% | Free (AU,BH,CL,CO,IL,JO,KR,MA,OM,P,PA,PE,S,SG) |
| 5401.20.00.00 | Of artificial filaments (200) | 11.4% | Free (AU,BH, CL,CO,IL,JO,KR, MA,OM,P, PA,PE,S,SG) |
This is the schedule, and the schedule is not the whole duty. The rates below are the published United States Harmonized Tariff Schedule for the revision named at the foot of this page. They do not include Section 301 duties, antidumping duties or countervailing duties, and for textiles of some origins those exceed the scheduled rate — a line reading 16.5% can land well above it. Nor is a rate of Free a statement that the goods enter free of charge: it is the general rate only, before any of the above. Which line a particular garment falls under is a classification decision, the difference between two adjacent lines can be several times the duty, and a preferential rate applies only where the goods actually qualify under that agreement’s rules of origin. Check with your broker before quoting a landed price.
