A Flexport Tariff Simulator alternative you can actually open
If your tariff tool just locked you out — or you never had a freight forwarder relationship to unlock it in the first place — CVDar gives you the same HTS duty estimate plus classification, compliance-risk flags, and a pre-purchase verdict. No account, no sales call.
How CVDar compares
| Capability | CVDar | Typical forwarder tool |
|---|---|---|
| Query without an account | Yes | Often gated |
| AI classify from product name | Yes (GRI reasoning) | Usually code-in only |
| AD/CVD order screening | 1,200+ active orders | Varies |
| Section 301 / 232 / UFLPA flags | Yes | Rarely |
| Pre-purchase go/no-go verdict | Yes | No |
| Freight booking integration | No (use your forwarder) | Yes (theirs) |
The honest trade-off: a forwarder's tool books the box; CVDar does not. If you want one tool for the duty/classification/compliance question and a separate forwarder for shipping, CVDar is built for that split.

Common questions
Is CVDar really free to use without an account?
Yes. You can look up any HTS code, run a landed-cost calculation, check AD/CVD exposure, and use the AI classification without creating an account. Unauthenticated use is rate-limited per IP to keep the service available for everyone; a free account raises the limits and adds search history. There is no "talk to our team" gate and no requirement to be a freight forwarder customer.
How does CVDar compare to the Flexport Tariff Simulator?
Both estimate US import duties by HTS code. The core differences: CVDar requires no login or Flexport customer relationship to query; CVDar adds an AI HTS classifier that starts from a plain product description (not just a code you already know); and CVDar flags compliance risk — active AD/CVD orders, Section 301, Section 232, and UFLPA exposure — alongside the duty rate. Flexport's tool is tightly integrated with its freight business; CVDar is a standalone reference that stays open.
Why would I need an alternative to Flexport's tariff tool?
Two common reasons. First, access: Flexport has periodically restricted its simulator to customers or limited usage, which catches brokers and importers who relied on it off guard. Second, scope: a freight forwarder's tool optimizes for shipping a box with Flexport, so it stops at duty estimation. Importers who also need classification, compliance-risk screening, and pre-purchase decisions often need a second tool anyway.
Does CVDar cover the same 2026 tariff regimes as Flexport?
CVDar covers the layers that determine what you actually pay: base HTS duty, Section 301 China tariffs, active AD/CVD orders, MPF, and HMF. For the 2026-specific regimes — Section 122 (under legal challenge), the expanded Section 232 on steel/aluminum/copper/autos/semiconductors, and the proposed Section 301 forced-labor duties — see our US tariffs 2026 status page, which tracks what is in effect, pending, and refundable.
Can I use CVDar while I'm sourcing on Alibaba or 1688?
Yes. The CVDar Chrome extension classifies products and flags duties directly on Alibaba.com and 1688.com product pages, so you see the US tariff exposure before you message a supplier. It shares the same data as the website and links back to the full HTS detail page for deeper analysis.
