Why not just use a general AI tool?

General AI tools can review documents if you know what to upload, what to ask and how to check the answer. MarginMining turns that review into a repeatable commercial workflow: structured intake, evidence checks, missing-data flags, confidence levels and action prompts for suppliers, brokers and internal teams. The value is not just reading files. It is knowing what to look for, what is missing and what to do next.

How does MarginMining work?

MarginMining combines structured document review, deterministic checks and AI-assisted evidence analysis. Uploaded shipment documents are classified and reviewed for the Import Cost Review. Where calculations or checks can be made directly, MarginMining uses structured logic. AI is used to interpret evidence, identify missing information and draft the Action Pack. Confidence levels are shown where the evidence is incomplete.

How is my data handled?

Customer files are stored securely with authenticated access controls. MarginMining uses Supabase for authentication, storage and database services, including row-level access controls so users can only access their own assessments and documents. MarginMining is currently in Beta as we continue expanding support across Australian shipment documents. MarginMining does not sell customer data.

Possible outcomes

Four things a review can tell you about one shipment.

Every Import Cost Review ends in one of four places. None of them is a promise of money back.

Nothing specific to question

The evidence you supplied did not contain a specific reason to question the duty treatment on this shipment.

This is not confirmation that the duty treatment is correct, complete or compliant.

More evidence needed

Key documents were missing or unreadable, so the duty charged on this shipment could not be checked against the paperwork yet.

This is not a finding either way. It tells you which document to get next.

Worth a professional review

Something specific in your documents is a documented reason to have the duty treatment looked at by a licensed customs specialist.

This is not a refund, a recovery amount or a statement that duty was overpaid.

Compliance point to check

Something in the evidence points the other way: an inconsistency or gap that is better reviewed before the next shipment clears.

This is not a compliance determination. It is a prompt to check with your clearance party.

MarginMining only reports duty it can observe in your documents. It does not calculate refunds, savings or recovery amounts, and it does not decide tariff classification or origin eligibility.
