MapleBOM

Canadian content

How much of your product is actually Canadian?

MapleBOM reveals the Canadian sourcing, foreign sourcing and country-of-origin gaps reported in your bill of materials — and how much of your purchasing nobody can currently account for.

Reported component sourcing is not regulatory Canadian content. A content determination follows specific rules and needs origin evidence, and MapleBOM makes no such determination. What it gives you is the reported starting position, including the share nobody can currently vouch for.

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

The problem

The number you are asked for and the number you can defend are not the same number.

It is easy to produce a Canadian-content percentage from a spreadsheet. It is hard to produce one you would put your name on, because a meaningful share of the underlying lines have an origin nobody has ever checked. Any figure calculated over those lines inherits their uncertainty without showing it.

01

An origin column is a claim, not evidence

A country recorded in an ERP usually has no certificate or attestation behind it. That distinction matters the moment somebody audits the number.

02

Unverified spend distorts the percentage

Every line with unknown origin is a line your content figure is quietly guessing about. MapleBOM sizes that guess in dollars.

03

Canadian sourcing is not Canadian origin

A Canadian supplier, a Canadian distributor and a Canadian factory are three different things, and only one of them counts.

The core output

The unverified share, in dollars.

Before any content figure means anything, you need to know how much of your purchasing it is silently assuming. MapleBOM ranks exactly that, largest first.

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

Origin shown as unknown because the file did not establish one — never because we could not guess.

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.
Future research Show four optional questions

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

Private beta

Canadian content and CUSMA

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

Analyze Canadian content → Private beta

Tariff exposure

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

Calculate tariff exposure → Private beta

Canadian supplier alternatives

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

Find Canadian suppliers → Private beta

Resolving unverified origins

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

Resolve unknown origins →

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.
