How to read this
The Special column on this line reads Free (AU,BH,CL,CO,D,IL,JO,KR,MA,OM,P,PA,PE,R,S,SG). The S in that list stands for USMCA, so goods that qualify as originating pay nothing here instead of the general rate of 37.5%.
No Section 338 program reaches this line, so a qualifying claim brings the duty to nothing.
From HTS Revision 18 (2026). Check this line in the official schedule before you make entry.
