The supplier origin declaration, and when you need one
Every component on your bill of materials that came from a supplier outside Vietnam needs a signed declaration from that supplier. This page explains what the declaration covers and how it fits into the record around it.
The obligations, by name
The documentation supporting an origin claim should exist before the shipment departs[1].

What the declaration states
The declaration is a short document, one per non-Vietnamese supplier, naming the component, the country where it was produced, and a signature and date from that supplier. It is fixed text with merge fields, not open drafting, so every declaration on a shipment reads the same way.
When you need one
You need a declaration for every component on your bill of materials whose supplier country is not Vietnam. A component bought through a Vietnamese distributor but produced elsewhere still needs the declaration naming where it was actually produced.
Getting it signed
The documentation supporting an origin claim should exist before the shipment departs[1]. A declaration chased down after the shipment has already left carries less weight than one already on file when the broker asks for it. The template is built so you can send it to a supplier and get a signature back without drafting anything yourself.
What the pack produces for this
One supplier origin declaration per non-Vietnamese supplier, generated from the same bill of materials that feeds the rest of the origin memo. Each declaration lists the component, the supplier and the declared country of manufacture, with a signature block and a date. The declarations support the record. They do not, on their own, decide origin.

Questions
- Does a signed declaration settle where my product originates?
- No. It records what a supplier states about where a component was produced. The determination on the finished product still belongs to the importer's counsel or broker.
- What if a supplier refuses to sign?
- The bill of materials flags that row as origin not stated, and the evidence inventory records the gap rather than filling it in for the supplier.
Have the record reviewed by the importer's customs counsel or licensed broker before use.
