See what others miss
From import evidence to the next right question.
MarginMining helps ecommerce founders review shipment evidence, spot cost gaps and turn the findings into practical actions for suppliers, brokers or internal teams.
How MarginMining works
Evidence in. Cost gaps out. Action Pack ready.
Upload evidence
Add shipment documents, invoices, duty statements, product data or landed-cost files.
Find the gaps
MarginMining reviews the evidence with you, surfacing supported findings, missing information, HS code questions and weak landed-cost assumptions.
Send the next question
Get a practical Action Pack with review signals, missing evidence and copy-ready questions for your broker, supplier or internal team.
What you get back
An Action Pack turns messy evidence into the next practical step.
Every Import Cost Review produces a copy-ready Action Pack: an evidence summary, supported findings and messages to send suppliers, clearance teams and your internal landed-cost file. Actions describe what the evidence supports and what still needs checking; final customs treatment sits with your clearance party.
Evidence checked
See which documents were reviewed and which evidence is still missing.
Review signals
See where duty, freight, origin, valuation or variant-cost assumptions are supported by evidence and where they still need verification.
Recommended first action
See the most useful next question to ask before the cost number is trusted downstream.
Copy-ready message
Use plain-English wording with your broker, supplier or internal team.
Import tools
Use import tools when evidence needs cleanup.
Import Cost Review is the main workflow. Import tools help prepare cleaner evidence before running or updating a review.
Evidence first. Never customs guesswork.
MarginMining does not provide customs, tax or legal advice.
It organises evidence, highlights review signals and prepares questions you can raise with your broker, supplier or internal team.
Source-backed signals
Review signals are framed around evidence so you can see why a question was raised.
Evidence-led wording
Findings describe what the evidence supports and what still needs checking. They are not final customs, duty or eligibility outcomes.
You stay in control
Use the findings to decide what to review, what to ask and who to involve.
Start with the cost question in front of you.
Review your last shipment and get an Action Pack showing what is missing, what to question and who to ask.
