8-digit subheadingFittings
This is a 8-digit subheading — a category, not a filing code. Pick the more specific code beneath it that best matches your goods; only a 10-digit statistical code can be used on a customs entry.
Duty rates
Ad valorem rate — a straight percentage of the declared customs value.
| Rate | Value and what it means |
|---|---|
| General rate (Column 1) | 5.3%Column 1 general Applies to most trading partners — the standard "normal trade relations" rate. |
| Special rate (Column 1) | Free (A,AU,B,BH,C,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG)Trade programs The country letters in parentheses are free trade agreement and preference programs. If your goods qualify under one of them, that rate replaces the general rate.
|
| Column 2 rate | 80%Non-NTR Reserved for the small group of countries that do not have normal trade relations with the US (currently Cuba, North Korea, Russia and Belarus). Almost no importer uses this column — if you are shipping from anywhere else, ignore it. |
| Unit of quantity | — How CBP expects the quantity to be reported on the entry summary. |
