TariffLens vs CBP CROSS
CROSS is the authoritative, free database of CBP binding rulings, the precedent that decides classification disputes. TariffLens is built on that same corpus: it surfaces the ruling that bears on your product, determines the 10-digit code, and computes the duty, instead of leaving the research to you.

The short version
CBP CROSS (Customs Rulings Online Search System, rulings.cbp.gov) is US Customs and Border Protection’s official, free, searchable database of CBP rulings, primarily binding tariff-classification, valuation, and country-of-origin rulings, roughly 221,000 of them, from 1989 to present, with keyword and Boolean search and cross-references to modified or revoked counterparts. It is the gold-standard corpus of classification precedent, and it is free. But it is a document search, not a classifier: you find and read rulings on similar merchandise and analogize to your own product yourself, and it computes no duty. TariffLens is built on that same corpus: on every classification it surfaces the specific CBP binding rulings that bear on the product (citing from a 200,000+ corpus with links to verify in CROSS), determines a full 10-digit HTSUS code with GRI reasoning, and computes the real-time US duty stack (Section 301/201/232/122, IEEPA/reciprocal, UFLPA, and AD/CVD). If you have the time and expertise to research precedent yourself, CROSS is the authoritative free source; if you want the right ruling surfaced automatically with a code and a duty, TariffLens is.
Use CROSS as the free, authoritative source of CBP ruling precedent. Use TariffLens to have the relevant ruling surfaced for your product automatically, with a defensible 10-digit code and the full computed US duty stack.
Side by side
TariffLens vs CBP CROSS, line by line.
| TariffLens | CBP CROSS | |
|---|---|---|
| What it does | Classifies your product, cites the relevant rulings, and computes the duty. | Lets you search existing CBP rulings and read them yourself. |
| Classification (description to code) | GRI reasoning to a full 10-digit HTSUS code, with the relevant rulings surfaced automatically. | None. You search for rulings on similar goods and analogize to your product yourself. |
| Ruling corpus | Cites from a 200,000+ corpus of CBP rulings, with links to verify in CROSS. | The authoritative, complete source itself, roughly 221,000 rulings, cross-referenced to revoked and modified counterparts. |
| Finding the relevant ruling | Surfaces the rulings that bear on your specific product on every result. | Manual keyword and Boolean search; you judge substantial similarity across many documents. |
| US duty computation | Real-time per-origin landed math across the full 2026 stack. | None. Duty appears only incidentally inside a ruling’s narrative. |
| Monitoring | Refreshed from CBP CSMS and the Federal Register; classifications reflect current measures. | No alerts when a relevant ruling is revoked or superseded; you re-check manually. |
| Cost | Self-serve subscription; sign up and start. | Free, government-published. |
Where TariffLens wins
TariffLens is built on the same corpus of CBP rulings that CROSS publishes. On every classification it surfaces the specific rulings that bear on the product (citing from a 200,000+ corpus with links to verify in CROSS), reasons through the GRI to a full 10-digit HTSUS code, and computes the real-time US duty for the origin country, so the research CROSS leaves to you is done automatically and tied to a code and a duty.
- Surfaces the relevant CBP rulings for your specific product automatically, rather than requiring manual keyword research across 221,000 documents.
- Cites rulings inline on a 10-digit HTSUS classification with GRI reasoning, turning precedent into a defensible artifact.
- Computes the full US duty stack per origin (Section 301/201/232/122, IEEPA/reciprocal, UFLPA, AD/CVD), which CROSS does not do at all.
- Confidence scoring, alternatives considered, and audit-ready exports, so precedent supports a filing decision.
- Self-serve with RESTful API and CSV bulk upload.
Where CROSS wins
CBP CROSS (Customs Rulings Online Search System, rulings.cbp.gov) is US Customs and Border Protection’s official, free, searchable database of CBP rulings, primarily binding tariff-classification, valuation, and country-of-origin rulings (HQ = Headquarters, NY/N = New York), spanning 1989 to present, roughly 221,000 rulings. It supports keyword and Boolean search and ruling-number lookup, and cross-references each ruling to its modified, revoked, or referenced counterparts. It is a search over existing precedent; obtaining a new binding ruling for your own product is a separate CBP process (the eRulings program), distinct from searching CROSS.
- The definitive, authoritative corpus of CBP classification precedent, nothing else carries the same legal weight.
- Roughly 221,000 rulings, cross-referenced to their modified, revoked, or superseding counterparts, so you can check whether a precedent still stands.
- Powerful keyword and Boolean search across Headquarters and New York rulings, 1989 to present.
- Completely free and login-free.
- Indispensable for defending or researching a classification position.
Where it can fall short
- It does not classify your product: you must find, read, and analogize to rulings yourself.
- No AI and no natural-language "which ruling applies to my item," no GRI reasoning, and no confidence scoring.
- No duty computation and no duty-stack assembly whatsoever.
- Coverage is not yet 100% of post-1989 rulings, and the interface is bare document search.
- No monitoring or alerts when a relevant ruling is revoked or a new one lands.
The differences that matter
What actually separates them.
The source of truth, and the tool built on it
CROSS is the authoritative corpus of CBP classification precedent, roughly 221,000 rulings, and TariffLens does not replace it: TariffLens is built on that same corpus and links back to it. The difference is retrieval and reasoning. CROSS gives you a search box over 221,000 documents; TariffLens surfaces the specific rulings that bear on your product, applies the GRI, and ties them to a 10-digit code and a computed duty. For verifying a citation or reading a ruling in full, CROSS is exactly right, which is why TariffLens links you there.
Search vs. surfacing the right ruling
Using CROSS well is skilled work: you form the right keyword and Boolean query, read many rulings, judge which merchandise is substantially similar to yours, and check whether each ruling still stands. That is real research, and free. TariffLens compresses it: on each classification it surfaces the rulings that bear on the specific product and cites them inline, so instead of starting from a blank search box you start from the relevant precedent, then verify it in CROSS. It is a superset of the research slice, not a substitute for the authoritative source.
CROSS has no duty math
CROSS is a document search: it computes no duty, stacks no tariffs, and assembles no landed cost. A ruling tells you the code CBP assigned to specific merchandise; it does not tell you what your shipment will cost to land in 2026 under Section 301, 232, IEEPA and reciprocal tariffs, and any AD/CVD order. TariffLens pairs the cited precedent with the computed duty stack per origin, so the classification and the bill come together. For a new binding ruling on your own product, both CROSS users and TariffLens users go to CBP’s separate eRulings program.
Which should you choose?

- You want the research done in seconds with a review queue and audit trail, then verified against CROSS.
FAQ
TariffLens vs CBP CROSS, answered.
Can I just use CBP CROSS for free instead of a paid classification tool?
CROSS is the free, authoritative source of CBP ruling precedent, and it is indispensable for reading and verifying rulings. What it does not do is classify your product (it is a document search, not a classifier), surface the relevant ruling automatically, or compute any duty. TariffLens is built on the same corpus and does those, then links you back to CROSS to verify. Many teams use both.
How many rulings are in CROSS, and does TariffLens use them?
CROSS contains roughly 221,000 CBP rulings from 1989 to present, cross-referenced to their modified and revoked counterparts. TariffLens cites from a 200,000+ corpus of CBP rulings drawn from the same source, surfacing the ones relevant to your product with links to verify in CROSS.
Does CROSS classify my product or compute duty?
No. CROSS lets you search existing rulings on similar merchandise, which contain the codes CBP assigned in those cases; you analogize to your own product yourself, and it computes no duty. TariffLens determines the 10-digit code with GRI reasoning, cites the relevant rulings, and computes the full US duty stack per origin.
Can CROSS give me a binding ruling for my product?
No. CROSS searches existing rulings; obtaining a new binding ruling for your own product is a separate CBP process (the eRulings program). TariffLens is not a substitute for a binding ruling either, it gives you a defensible classification grounded in existing precedent, which is what most day-to-day decisions need.
