Flexport tariff simulator alternative for Planning Use
Planning Use only. Broker review required for Entry Use.
A tariff simulator is useful when an importer wants a fast duty exposure view. The weak spot is the same every time: the estimate is only as good as the classification, origin, value, and trade-remedy facts underneath it.
quick answer
Use TariffCase when you need the evidence file behind the simulation. Compare any Flexport tariff simulator workflow by asking whether it records Product Facts, Missing Facts, HTS Candidate families, Authority Sources, and the assumptions behind the duty exposure.
what to compare
Simulators are good at turning inputs into a number. TariffCase is meant to check whether the inputs are safe enough for Planning Use. That means reviewing supplier codes, product photos, origin evidence, invoice value, set contents, and official sources.
The comparison should focus on input quality. If the HTS Candidate is weak, every downstream duty estimate is weak too.
missing facts
Missing Facts include origin support, supplier-code depth, material or function, value basis, trade remedy exposure, Incoterms context, accessories, and whether the product is a set or part.
If these facts are absent, the simulator may still return a number. TariffCase should keep the record open and show what is missing.
HTS candidate notes
TariffCase names HTS Candidate families before calculating duty exposure. The record should show why the family is plausible, which official sources were checked, and what facts could move the product elsewhere.
For a Flexport simulator comparison, ask whether the estimate can be traced back to the product evidence and Authority Sources.
authority sources
- USITC HTS
- CBP CROSS
- 19 CFR 177.2
- CBP ruling program
- Public Flexport pages as workflow context, not customs authority
Authority Sources should be official sources for classification and tariff review. Calculator pages can explain workflow assumptions, but they are not the authority for the record.
TariffCase workflow
TariffCase starts with a Duty Surprise Scan, then builds a Classification Record when the SKU needs support. The record contains Product Evidence, Missing Facts, HTS Candidate families, Authority Sources, duty exposure notes, and review status.
This fits importers who want to know whether a tariff simulation rests on real evidence or on guessed fields.
review file contents
A useful simulation packet should include the product description, supplier invoice, origin support, value basis, HTS Candidate families, trade remedy assumptions, Missing Facts, Authority Sources, and the date of review.
If the number changes after a new code or origin fact appears, keep both scenarios in the record. The difference is often the duty surprise the importer needed to see before the purchase order.
Do the same when value assumptions change. A sample, discount, assist, or freight treatment can make a scenario misleading if the value basis is not written down.
When the scenario drives a sourcing decision, save the version sent to the buyer or founder.
questions importers ask
Is a simulator enough for planning?
It can help with a rough scenario. The inputs still need an evidence check.
What should be checked before simulation?
Classification path, origin, value, trade remedies, and product facts.
What is the next step?
Run a Duty Surprise Scan on the SKU that drives the largest margin risk.

planning boundary
This Flexport tariff simulator alternative page is a planning artifact. It is not an Entry Use decision, not a binding ruling, and not a legal opinion. The importer remains responsible for reasonable care and must obtain broker or customs authority review before filing.
