MapleBOM

Country-of-origin documentation

Can you prove where your components come from?

MapleBOM identifies the components with missing or unverified country of origin, and prioritizes the gaps that matter most — so a job that feels unbounded becomes a short, ranked list.

Analyze provenance gaps Analyze my BOM

MapleBOM reports only what your file establishes. It never infers origin from a supplier, a manufacturer or a distributor, and it never guesses.

BOM uploads are analyzed transiently in memory and are not retained. How this works

The problem

Origin documentation is a per-line problem that gets asked as a per-product question.

Nobody asks about one component. They ask about the product, and answering means resolving hundreds of lines held across a distributor portal, a broker's file and somebody's inbox. The work is not hard, it is just unbounded — until you know which lines actually matter.

01

The gap follows how you buy

Parts bought direct from a manufacturer usually carry an origin. Parts bought through a distributor usually do not.

02

Blank and "various" are different problems

One means nobody asked. The other means somebody did, and the answer was more than one country. Only one of them has somebody to chase.

03

It is finite, once it is ranked

Unverified origin feels like an endless task because it is never sorted by importance. Sorted by spend, it is usually a short list of suppliers.

The core output

Turn a percentage into a work list.

MapleBOM ranks every unresolved component by the money attached to it, and names the handful of suppliers who between them can close most of the gap.

In the sample analysis, 480 components have no established country of origin — but 10 supplier conversations would account for 80% of that exposure.

What you get

A prioritized exposure view of one product, in about ten seconds.

  1. Find the focus rows

    Components ranked by covered annual spend, with the evidence and next fact behind each priority.

  2. Separate the evidence

    Reported origin and supplier country shown as separate views, with Unknown / Unverified kept visible instead of inferred.

  3. Leave with a worklist

    Missing economic inputs, supplier concentration and downloadable rows make the next conversation finite.

What MapleBOM will not do

Provenance is only useful if it is true. These are the rules the analysis follows, without exception:

  • We never infer country of origin from a supplier, manufacturer, distributor or company nationality. Buying a part from a Canadian distributor does not make it Canadian.
  • Anything the file does not establish is reported as Unknown / Unverified, with the reason it is unresolved.
  • Country values we cannot interpret are surfaced, not silently dropped or guessed.
  • V0 makes no CUSMA, tariff, Canadian-content or Buy Canadian determination. Those require rules and evidence this tool does not yet have.
  • Facts you supplied, figures we calculated, and information nobody has are labelled separately throughout.

These capabilities are not built. The current product is the Supply Chain Exposure analysis above.

Private beta

Resolving unverified origins

Track evidence and supplier attestations for the components nobody can currently vouch for.

Resolve unknown origins → Private beta

Tariff exposure

Understand which components and purchasing categories may be affected by changing tariffs.

Calculate tariff exposure → Private beta

Canadian content and CUSMA

Identify documentation gaps and the components that would need deeper qualification.

Analyze Canadian content → Private beta

Canadian supplier alternatives

Discover foreign components that may have Canadian manufacturing or sourcing alternatives.

None of these are built. Clicking one tells us which capability you want, not what you would get back — no figure anywhere else in MapleBOM depends on one that does not exist. The current report remains the Supply Chain Exposure analysis shown above.

Built in Canada

An independent project.

MapleBOM is built by Tyson Hamilton, a Canadian software engineer building better trade and supply-chain tools for Canadian manufacturers.

It is early, and deliberately narrow: it reports what your bill of materials establishes, and says plainly what it does not.
