Question

How do I know if my HTS code is internally consistent?

Enter your HTS code along with product name, material, primary use, finished/part status, invoice description, and country of origin. The tool compares each field against the HTS description and surfaces Red (clear error), Yellow (review needed), or Green (consistent) signals across six checks.

Formula / Criteria

What to check

Six checks run in parallel: HTS existence in current tariff schedule, material alignment, use/function fit, finished/part structure, invoice description match, and kit/set retail logic. Each emits Green/Yellow/Red.

Use This Tool

When to use it

Use this before filing customs entries to catch obvious classification errors—wrong material, mismatched use, or invoice descriptions that don't support the HTS.

Official Source Note

Source-check required

This tool does not establish binding classifications. It is a pre-flight review only—use it alongside broker review and official HTS verification.

FAQ

Common questions

What does consistency check do?

It cross-checks six input fields against the official HTS description to surface likely errors or misalignments before they appear on customs paperwork.

Does it use AI to classify?

No. It uses deterministic text matching and structural rules. This is a pre-flight audit, not a binding classification.

Why does a Red finding appear even when the code "exists"?

Existence only means the code is in the schedule. Red flags surface when your material, use, or description does not logically match the HTS heading description.

Can I use this for the EU?

Yes—switch destination to EU. The tool pulls the active tariff for the destination jurisdiction when available.

Is my data saved?

No. This free audit runs without auth and does not persist data. Paid Classification Cases in the dashboard can save audit history.

What if I have missing fields?

Empty fields are skipped silently. Skipped checks do not appear in the result. Fill in as much as you can for a stronger audit.
