Free Tariff Calculator Comparison 2026: TariffCheck, Flexport, Freightos
Compare TariffCheck, Flexport, and Freightos on free access, HTS lookup, drug-tariff coverage, and pricing so you can pick the right calculator faster.
As of 2026-04-21, TariffCheck is the best fit when you want a small-business tariff calculator with AI HTS lookup, country comparisons, PDF export, and a separate pharmaceutical checker. Flexport fits import teams already living inside a brokerage or forwarding workflow, while Freightos is strongest when freight pricing is the main job and duty estimation is a supporting step. None of the three is universally best; the right pick depends on whether your bottleneck is HTS classification, landed-cost planning, or freight procurement.
TL;DR
- TariffCheck is the best fit for SMB importers who want plain-English HTS classification, landed-cost math, and a dedicated pharma module in one product.
- Flexport is the best fit for customs and logistics teams that want official-source duty logic, FTA handling, and a path into a larger enterprise logistics stack.
- Freightos is the best fit when you start with freight quotes and want a lightweight duty estimate on the side, not a deep tariff-compliance workspace.
- TariffCheck has the clearest public entry pricing: 3 free uses, then $5 one-time for 50 credits.
- Flexport's official pages conflict on free usage, and Freightos' public duty page says its estimates do not yet include Trump's 2025 tariffs.
Who each tool is built for
TariffCheck is built for first-time and mid-volume U.S. importers who do not want to start with a 10-digit HTS code. Its public tool page is centered on plain-English product input and full duty stacking, and the current build adds country comparison and PDF export.
Flexport's Tariff Simulator is built for importers who need a more compliance-oriented U.S. customs view and may already buy brokerage or forwarding services from Flexport. Its FAQ emphasizes official government sources, 10-digit HTS precision, preferential treatment, and updates within 24 to 48 hours of official changes.
Freightos is built for shippers who start from marketplace rates, transit planning, and freight procurement, then layer duty estimation into that process. Its public duty calculator is easy to reach from the content hub, but the workflow is lighter than TariffCheck or Flexport on tariff-specific detail.
Side-by-side feature comparison
| Feature | TariffCheck | Flexport | Freightos |
|---|---|---|---|
| Free tier | 3 free uses with sign-in | Official pages conflict: homepage shows 5 free searches, FAQ says unlimited free use | Free public estimator page |
| HTS auto-classify | Yes, AI from plain-English description | Yes, plain-English search suggests 10-digit HTS codes | Partial: keyword lookup, then choose HS code |
| Section 301 included | Yes | Yes | Public duty page says Trump's 2025 tariffs are not yet included |
| Multi-origin compare | Yes, current build compares CN/VN/IN/MX/TH | Yes, country comparison via recalculation | No public side-by-side compare documented |
| Pharma/drug module | Yes, dedicated consumer drug checker | No public drug-specific module | No public drug-specific module |
| API | No public API documented | No public tariff-calculator API documented | Freight APIs exist; no public duty-calculator API documented |
| Export to PDF | Yes, in current build | No public PDF export documented | No public PDF export documented |
| Login required | Yes for calculator use | No for initial public use; sign-up is pushed for unlimited access | No login shown on public estimator page |
The cleanest product split is this: TariffCheck leads on small-business usability, Flexport leads on customs-workflow depth, and Freightos leads when freight booking context matters more than tariff nuance.
Pricing model comparison
| Tool | Free tier limits | Paid tier | Enterprise |
|---|---|---|---|
| TariffCheck | 3 free uses with Google sign-in | $5 one-time for 50 credits | No separate enterprise plan publicly listed |
| Flexport | Homepage shows 5 free searches; FAQ says no registration or usage limits | No public paid tariff-simulator tier listed | Pricing on request |
| Freightos | Free public import-duty estimator | No public paid duty-estimator tier listed | Pricing on request |
TariffCheck is the only one of the three with public self-serve entry pricing on the site. For Flexport and Freightos, the defensible wording is still "pricing on request."
Strengths and weaknesses — TariffCheck
TariffCheck's main strength is workflow compression. The core calculator handles tariff stacking and landed-cost math, while the separate drug tariff checker covers a use case that the other two do not expose publicly.
It is also opinionated around 2026 U.S. tariff reality. The current build supports AI HTS identification, country comparisons, saved history, and PDF export, which is useful for fast internal planning.
The weakness is that TariffCheck is not truly unlimited-free. The public pricing page shows 3 free uses and then a one-time credit pack, and there is no public API or enterprise pricing surface.
Strengths and weaknesses — Flexport
Flexport's strongest point is source discipline. Its FAQ says the Tariff Simulator uses HTSUS, USTR notices, Commerce announcements, and CBP guidance, with updates landing within 24 to 48 hours after official publication.
Flexport also looks more enterprise-ready than the other two because the simulator sits inside a larger forwarding and customs platform.
The tradeoff is ambiguity at the public self-serve layer. As of 2026-04-21, the homepage shows "0 / 5 free searches" while the FAQ says no registration or usage limits. There is also no public PDF-export or drug-specific tariff workflow documented.
Strengths and weaknesses — Freightos
Freightos wins on accessibility if your first question is "what will freight cost?" rather than "what is the exact duty stack?" The marketplace, rate tools, and duty-estimator content live in the same public navigation.
Its HS and duty tools are also easy to approach without creating a dedicated customs workflow.
The weakness is that the duty side looks less current for 2026 U.S. tariff complexity. Freightos' public import-duty page explicitly says its customs estimates do not yet include Trump's 2025 tariffs, so I would treat it as a directional estimator, not the first choice for tariff-sensitive decisions.
Which free tariff calculator should you use?
| User type | Best fit | Why |
|---|---|---|
| First-time SMB importer | TariffCheck | Fastest path from product description to landed cost |
| Sourcing manager comparing origins | TariffCheck or Flexport | Both support cross-country tariff planning |
| Existing Flexport customer | Flexport | Best ecosystem fit for brokerage and logistics workflows |
| Freight buyer starting from quotes | Freightos | Freight research is the center of the workflow |
| Pharma patient, benefits team, or health writer | TariffCheck | Only one with a public drug-specific tariff module |
Use TariffCheck for fast self-serve tariff planning, Flexport for trade-ops workflow depth, and Freightos when freight discovery is the main job and duty estimation only needs to be directional.
Frequently Asked Questions
Is TariffCheck really free?
TariffCheck is free to try, but it is not unlimited-free. The public pricing page shows 3 free uses with Google sign-in, then a $5 one-time pack for 50 credits.
Does Flexport have a free tariff calculator?
Yes. Flexport's Tariff Simulator is publicly accessible at tariffs.flexport.com, but its own pages conflict on the exact free limit as of 2026-04-21. The homepage shows 5 free searches before sign-up, while the FAQ says there are no registration requirements or usage limits.
Can Freightos calculate import duty?
Yes. Freightos publishes a free U.S. import-duty calculator and an HS lookup workflow that lets you estimate duties from product terms and shipment inputs. The caveat is that its public duty page says the estimates do not yet include Trump's 2025 tariffs.
Which calculator has the best HTS auto-classification?
TariffCheck is the best fit if you want AI to turn a plain-English product description into a likely HTS classification and landed-cost estimate in one step. Flexport is strong if you want search-assisted 10-digit HTS identification backed by official-source customs logic, while Freightos is more of a keyword lookup flow.
Which tool supports the 2026 pharmaceutical tariff?
TariffCheck is the clearest choice because it has a dedicated public drug-tariff module covering 57+ named drugs and exemption status. Flexport's simulator changelog shows pharmaceutical tariff updates, but there is no public patient- or drug-level module, and Freightos' public tools do not show a dedicated 2026 pharmaceutical tariff calculator.
Is there an open-source tariff calculator?
Not among these three products. TariffCheck, Flexport, and Freightos are all proprietary tools, and none publicly positions its tariff calculator as open source.
