6-digit headingOther
This is a 6-digit heading — 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
No rate is published at this level — check the specific 10-digit statistical code beneath it.
| Rate | Value and what it means |
|---|---|
| General rate (Column 1) | See 10-digit codeColumn 1 general Applies to most trading partners — the standard "normal trade relations" rate. |
| Special rate (Column 1) | —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 | —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. |
