Every tier, down to the fibre.
A garment's supply chain is not a list of suppliers: it is a chain in which each company knows only the one above it. Tramaproof rebuilds it from the documents, derives the tiers from them and shows you exactly where it stops.

The hierarchy builds itself
The tier is not a pre-filled field: it is the distance from the finished garment, computed from the links. If a link changes, the tier updates by itself.
Every link says who declared it
A company enters the chain because somebody declared they bought from it, and that declaration has a document and a date.
Where the chain stops is where the work begins
The node nobody has named yet is drawn, not hidden. That is where the next request starts from.
What the map is used for.
The map answers three questions: who makes this garment, where each stage happens, and which of those companies has shown a document for what it declares.
From the label to the fibre
Start from a coat and its bill of materials. The first tier is already there: the companies you buy from. Each of them names who sold it the fabric or the yarn, and the drawing grows one tier at a time, with the material each company sells to the one above.
A company nobody has named yet
Where a company has declared nothing upstream, the map draws a dashed end. Open it and ask that company to declare who supplies it. When it answers, the next tier appears.
What expires, and where
Open a company on the map to see its country, its tier, the products it appears in and its certificates with their state. An expired certificate shows where it matters, with the action to ask for its renewal.
The same companies can be grouped by country, when the question is where production sits rather than how far it is from you.
The map shows only the purchases your suppliers declared to you. What a supplier buys for its other customers stays out of it. Who sees what →
Questions about the map
Do we have to enter the tiers ourselves?
No. The tier is the distance from the finished product, computed from declared purchases. You enter your own suppliers; the rest follows from what they declare.
What do the marks on the map mean?
Three states: a company that answered for itself, a company named by someone else that has not answered yet, and a dashed end where nothing has been declared. There is no fourth state for a guess.
Can we look at one component only?
Yes. Filtering by component, such as the shell fabric or the lining, narrows the whole chain behind it.
Does the map show a supplier's other customers?
No. A brand sees only the purchases declared to it, and a supplier's sources are never shown to a customer they were not declared to.
How deep can the chain go?
As far as the declarations go. Each company that answers can name its own suppliers, and the map follows every declared purchase up to eight tiers from the finished product.
Can we start from a spreadsheet?
Yes. A bill of materials imported from Excel or CSV can carry the supplier of each line, and those suppliers become the first tier of the map.
