HTS code known
Paste a 10-digit code and origin to check whether Moya sees Section 301 signals or unresolved code risk.
Section 301 tariff check
Check Section 301 tariff exposure before broker review
Section 301 exposure depends on HTS code, product facts, origin, Chapter 99 instructions, and exclusion status. Moya helps identify the visible signals and the questions that still need verification.

Check one product row
Moya works best on one product or supplier row at a time. Start with the item where the code, duty, or product facts feel uncertain.
Start with one code or product
Paste an HTS code, supplier HS code, product description, and country of origin.
Built for one-product checks. For a list, start with the row where the supplier code or duty looks least certain.
Important: AI output requires professional review

What Moya checks
The tariff result is only useful if the classification path is credible. Moya keeps the code review and tariff review connected.
- Whether the candidate HTS path is specific enough for tariff checking.
- Visible Section 301 list and Chapter 99 signals in the reviewed data.
- Exclusion signals where active reviewed data is available.
- Classification uncertainty that could change the tariff answer.
Why tariff-only answers can mislead
A tariff lookup can look clean while the underlying HTS code is wrong or too broad.
- A 6-digit HS code is often too broad for Section 301 analysis.
- The same product family may contain tariffed and non-tariffed US subheadings.
- Effective dates and exclusion status require current data review.
Common checks
Only supplier code known
Paste the supplier HS code and product description so Moya can first expand the US HTS candidates.
Tariff surprise
Use Moya when a broker, carrier, Shopify app, or landed-cost calculator shows an unexpected duty estimate.
Questions this page answers
Can a 6-digit code answer Section 301 exposure?
Usually not with enough precision. Section 301 analysis normally needs a more specific US HTS path and the relevant Chapter 99 context.
Does Moya show exclusions?
Moya can surface reviewed exclusion signals where available, but exclusion status is date-sensitive and must be verified before filing or pricing decisions.
