These rows have the largest covered annual spend and an explicit non-Canadian reported origin, supplier country, or both. Unknown geography is kept as a data gap, not treated as foreign evidence.

How to read this list Annual spend = entered annual spend, or annual quantity × unit cost. Reported origin = manufacturing origin stated in the file. Supplier country = commercial relationship location. Unknown / Unverified is a data gap, not foreign evidence.

This is invented data.

The bill of materials behind this page describes a fictional packaged process line. No company, product, supplier, part number or price on this page is real. It exists so you can see exactly what MapleBOM produces before uploading anything of your own. Download the sample BOM to check the arithmetic yourself.

Economic exposure

Keep the evidence views separate.

All figures in this section use covered annual spend. Reported origin is the manufacturing-origin value entered in your file. Supplier country is the location of the commercial relationship. Neither is inferred from the other.

Annual-spend figures assume one consistent input currency. MapleBOM does not detect or normalize mixed currencies.

Spend concentration describes recorded supplier shares. It does not establish that another source is unavailable or that any supplier is the sole source.

Reported origin exposure

Reported sourcing by country.

Shares are of annual purchasing, not of component count. These are the origins your file reports. MapleBOM does not verify them, and attributes a country only where the file states one — never from a supplier or a manufacturer name.

Tariff classification coverage

748 of 1,536 components carry an HS code

That is 48.7% of lines and 47.2% of annual purchasing. HS classification is the prerequisite for any tariff analysis. MapleBOM records the codes your file supplies and does not classify anything itself.

Missing origin evidence

Close the highest-value evidence gaps.

After reviewing confirmed exposure above, close the highest-value missing-origin evidence gaps. These components have no established country of origin, ranked by the money attached to them.

Unverified annual purchasing

$2.49M

21.2% of annual purchasing across 480 components.

The largest 142 of those components carry $2.00M — 80% of the total exposure. The other 338 account for the rest.

Why each line is unresolved

A blank cell and a cell that says "Various" are different problems. Both are unverified; only one of them has somebody to ask.

Reason	Components	Annual purchasing	Share of gap
Not provided The country column was blank or said nothing	358	$1,849,318	74.1%
Ambiguous The cell named more than one origin, or deferred to the supplier	122	$644,821	25.9%

7 unresolved components carry no unit cost, so they do not appear in the ranking above.

Origin is reported as unverified because the file did not establish one. MapleBOM never infers origin from the supplier, the manufacturer or the distributor.

Origin coverage is the share of that supplier's annual purchasing whose country of origin your file establishes. The concentration index is a Herfindahl-Hirschman index over supplier shares, shown as a descriptive measure of your supplier base — not a regulatory finding.

How we read your file.

Every figure above comes from the columns below and nothing else. No external data was applied. Every figure on this page is derived only from the file you provided.

Spend basis: Every costed line supplied an annual quantity. Spend = annual quantity x unit cost.

Data quality

18 Lines with no unit cost 18 of 1,536 lines carried no unit cost. Entered annual spend remains usable, but annual spend cannot be calculated for the other affected lines.
122 Country values naming more than one origin Spend cannot be attributed to a single country for these lines, so they count as unverified. Values seen: "Various", "See supplier", "Asia", "EU", "Multiple", "Imported".
