Your chain, through a customs lens.
BorderAudit maps your complete import flow from the declaration data HMRC (His Majesty’s Revenue and Customs) already holds — origin country to supplier to commodity to duty outcome — and shows where supply-chain decisions are creating duty exposure, or leaving preference unclaimed.
Supply-chain decisions are customs decisions. Most are made blind.
Every sourcing choice — which supplier, which origin, which route — sets a duty outcome that repeats on every shipment down that lane. But the customs consequences live in declaration data nobody looks at, spread across thousands of lines. That’s where the exposure hides, and where the opportunity does too.
Origin → supplier → commodity → duty. One picture.
Supply chain analysis rebuilds your import chain from your customs declarations and draws it as an interactive Sankey diagram — a flow map where the width of every band is the value moving through it. In most import books, a small share of flows carries the bulk of the duty; on the map, that share is impossible to miss.
Click any flow to open the declarations behind it — from country-level overview down to individual MRN (Movement Reference Number) and item level. If it’s on the map, the evidence is one click away. See the full platform →
From declaration data to decision, in six stages.
No spreadsheets to prepare, no systems to integrate. You grant access once; the platform does the rest — and keeps the map current as new declarations land.
- 01 · CONNECTGrant access onceAuthorise BorderAudit against your HMRC declaration data through Government Gateway. No data upload, no integration project, no change to how your goods move.
- 02 · RECONSTRUCTEvery line, mappedEach import line is mapped by origin country, supplier, commodity classification and duty outcome — on a platform that analyses 4.4 million declaration lines a day.
- 03 · DRAWThe chain, drawnThe Sankey builds itself from the mapped lines: origin → supplier → HS (Harmonised System) chapter → duty outcome, with each flow weighted by the value moving through it.
- 04 · OVERLAYPreference and anomalies, in placeTrade-agreement preference is overlaid flow by flow — claimed against available — and classification anomalies are flagged exactly where they sit in the chain.
- 05 · DRILLOverview to declarationAny flow opens into its underlying declarations, down to individual MRN (Movement Reference Number) and item level — so every pattern on the map can be evidenced.
- 06 · ACTExposure becomes actionPreference gaps route into an origin and preference audit, overpayments become reclaims — generally recoverable up to three years from the entry — and sourcing options get a duty line.
Three teams, one map.
Sourcing with the duty line visible
When two suppliers offer the same product from different origins, the tariff difference is part of the price. The map puts customs cost into sourcing decisions before the contract is signed — not after the goods clear.
Exposure you can budget
Duty exposure quantified by origin, supplier and lane — so budgets are built from actuals rather than averages, and the handful of flows carrying most of your customs cost are named.
The pattern, before HMRC sees it
Post-clearance checks look for patterns. The same map shows you systematic issues first — a repeated misclassification down one lane, a relief never claimed on one route — while there's still time to put it right on your terms.
The platform behind the picture.
Free to start. Flat to scale.
Summary supply-chain views on the free tier — connect once and see the shape of your chain. No card required.
The full interactive Sankey with preference overlay, anomaly flags and drill-down to declaration level — plus the platform's full audit tooling.
For intermediaries and platforms serving many importers — flat platform economics, white-label or co-branded.
Pricing is flat at every tier — never a success fee, never a percentage of what the map finds. Duty recovery is one outcome of the platform, not the price of it.

Supply chain analysis tells you where to look. These are the places it usually points.
Where you stand
The map shows your own flows; benchmarking shows how your customs profile compares with sector peers. One tells you where to look, the other where you stand.
The preference gap, audited
When the overlay shows flows entering at full rates that appear to qualify for preference, an origin and preference audit turns the gap into evidence — and into a reclaim.
Chains built on preference
Textile supply chains are where origin decisions bite hardest: our analysis of 2.3 million textile declaration lines found preference gaps on 53% of them.
Part of one platform
Supply chain analysis runs on the same declaration data as the rest of BorderAudit — audit automation, reclaims and compliance analytics from one connection.
