Check up to 25 US HTS numbers against the active USITC revision, identify codes not found in the current schedule, and download a browser-only review CSV.
Check a current schedule baseline
Paste exact codes or a small catalog extract. Results will show the active source revision, code presence, official description, units, and raw duty-column text.
Compare the exact number with the active USITC HTS edition or revision, record the revision and effective date, and review the current description, units, duty columns, legal notes, and product facts. A code that still exists may nevertheless be unsuitable for a changed product or origin scenario.
Exact-code status is based on the active USITC HTS revision stored by TariffCatalog. The checker does not infer replacements, decide classification, or combine Chapter 99, Section 301, Section 232, AD/CVD, quotas, or fees into the result.
Use the free check before reusing supplier, broker, marketplace, or catalog HTS data. Use the paid monitor to baseline larger catalogs, retain the source revision, recheck after a new official revision is imported, and export affected rows.
USITC publishes a basic annual edition and can publish multiple revisions during the year. Verify the complete current entry and legal notes at USITC, then check product facts and other trade measures separately.
Official source notes and calculator assumptions should be reviewed before shipment, label purchase, invoice filing, or customs entry.
A new revision can affect more than the visible number. The description, reporting suffix, unit of quantity, general duty text, special-program text, Column 2 text, chapter notes, or related Chapter 99 provisions may change. A catalog comparison therefore needs a versioned snapshot, not a timeless code column.
| Field | What to compare | Why it matters |
|---|---|---|
| HTS number | Exact code presence and statistical suffix | A missing or replaced number needs official research before reuse. |
| Description | Current wording and hierarchy | A surviving number may have revised scope or reporting detail. |
| Units | Primary and secondary quantity units | Catalog and entry data may need additional quantity fields. |
| Duty columns | Raw general, special, and Column 2 text | Specific or compound wording should not be flattened into an unsupported percentage. |
| Revision evidence | Revision code, effective date, source URL, and check time | The record shows which official schedule supported the review. |
The paid monitor supports the evidence and queue portion of this workflow. It remains a preparation system, not a binding ruling service or customs filing system.

A catalog may contain 6109.10.00.12 and 8507.60.00.90. The tool checks each exact number against the current revision, records the source version, and shows the current schedule text. A not-found result means the row needs official research; it does not identify a replacement automatically.
USITC publishes a basic annual edition and can publish multiple revisions during the year. Verify the complete current entry and legal notes at USITC, then check product facts and other trade measures separately.
A current code can still be wrong for a product, and a missing code does not prove which replacement applies. Confirm the product facts, legal notes, origin, entry date, and additional measures before filing.
No. USITC publishes a basic annual edition and may publish multiple in-year revisions. The announcement archive lists official publication dates.
The exact normalized number was not found in the active stored revision. Recheck the number at USITC and research the current legal structure; do not assume a replacement from a similar description.
No. It confirms code presence only. Correct classification still depends on the product material, function, construction, components, use, legal notes, and other relevant facts.
US HTS duty lines may contain free, ad valorem, specific, compound, special-program, or other source wording. Showing raw text avoids converting a complex duty expression into a false universal percentage.
Yes. Paste one code per line or simple CSV rows in the free checker. Paid accounts can create versioned baselines for larger catalog batches and export the saved review list.
It saves each SKU and exact code with the active revision snapshot, keeps one-time and monthly credit use in the existing ledger, rechecks saved rows against the active revision, and exports baseline/current fields and change status.
Not in its change status. It monitors ordinary HTS entry fields. Chapter 99 and trade-remedy scope require separate official checks using origin, date, product scope, and governing documents.
