Search by product, not by country rumor
Start from what is being shipped, not from a guess that “Vietnam makes this.” The records show who actually filed shipments into the US for that category.
Find suppliers
Find the factories already shipping your product
Supplier discovery from US import records: who ships it, how often, and which American buyers already buy from them — not a directory of self-reported factories.
The other direction
The same customs question, pointed at factories
Portaxo works both ways. Search a product to find US importers — or switch to suppliers to find the overseas companies already moving that product into the United States, with the customers sitting on the other side of those shipments.
Rank by activity and factory signals
Shipment volume, recent activity, customer count, and heuristic factory evidence help separate a plant that makes the goods from a trader that moves other people’s freight.
Open customers, then reach people
Drill into a supplier’s known US customers without leaving the workspace, then run contact discovery when you are ready to talk to a buyer or a plant.
Use cases
Who uses supplier discovery
Same product engine. Different question on the other side of the shipment.
Sourcing teams
Find plants already proven in the US lane for a category, with named customers as diligence.
Exporters mapping competitors
See which overseas suppliers own the shelf at the importers you want — before you pitch.
Distributors validating supply
Check whether a claimed factory shows up in shipment history, or whether the volume sits elsewhere.
Questions
Straight answers
How do I find factories already shipping my product?
Search the product the same way you would search for buyers, then switch to supplier discovery. Portaxo returns overseas suppliers that appear in US import records for that product, with customer counts, shipment activity, and the buyers they already ship to.
Is this the same as Alibaba search?
No. Alibaba shows who claims to make a product. Portaxo shows who has already shipped it into the United States according to customs records — with named customers and volume. Claims and shipments are different kinds of evidence.
Can I see who a supplier already sells to?
Yes, once the supplier profile has been loaded. Customer relationships come from the supplier's own trade page and show who they ship to, with product descriptions and shipment periods where available.
Does supplier search use the same credits as buyer search?
Credits are spent on discovering and unlocking companies and contacts. Browse what you already unlocked for free. See the pricing page for the current plan allowances.
