How to read this

The Special column on this line reads Free (A+,AU,B,BH,CL,CO,D,E,IL, JO,KR,MA, OM,P,PA,PE,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 12.5%.

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.
