Will this satisfy every broker's request?

The memo organizes the records a broker commonly asks for, in the order a broker asks for them. Individual brokers can ask for more than this list, and no page here states that any specific broker's request is satisfied by it.

What if my supplier will not confirm where a component was produced?

The record flags that row as origin not stated, to be obtained from the supplier, and the supplier origin declaration template is what you send them.

What a US customs broker asks a Vietnamese supplier for

A broker evaluating an origin claim wants a small, specific set of records from the factory, covering where each component comes from, what was done in Vietnam, and evidence that can back both up. This page lists what a broker typically asks for and where each item lands in the origin memo.

The obligations, by name

The documentation supporting an origin claim should exist before the shipment departs^[1]. US Customs conducted inspections of factories in Vietnam in July 2026 examining value-added and origin^[2].

The bill of materials, by origin

A broker wants component, supplier, supplier country and cost, with supplier country meaning where the part was produced, not where it was bought. The origin memo builds this table directly from your costing sheet. Any row missing an origin country is flagged as one to chase down before the record is finished.

The processing record

Alongside the bill of materials, a broker wants the steps performed in Vietnam, what was done, with what equipment, and for how many labor hours. The memo lists these steps in order and pairs them with a plain description of what arrives at the factory and what leaves it.

Evidence on request

US Customs conducted inspections of factories in Vietnam in July 2026 examining value-added and origin^[2]. A broker knows an inspection can follow the paperwork, so it asks which records the factory can produce, among them purchase invoices, production logs, labor records, equipment lists, photos and video, and quality certificates. The memo's evidence inventory lists what you have and flags the gaps.

What the pack produces for this

The origin memo assembles the bill of materials, the processing table, the evidence inventory and a supplier origin declaration for each non-Vietnamese supplier, ordered the way a broker asks for them. The documentation supporting an origin claim should exist before the shipment departs^[1]. The pack organizes what the broker will look for. It does not decide what the broker or the importer's counsel concludes from it.
