S INC Corporation is a Tokyo-based trading company connecting Japan, ASEAN, and the Middle East — handling copper cathodes, copper scrap, and other non-ferrous metals and industrial materials end to end, from sourcing through export and logistics.
"Go to the site. Verify the goods. Deliver as promised."
The foundation of our business since day one.
We verify the goods, inspect, and document. You get what the specification says — with inspection records and photos as evidence of the transaction.
Since 2014, we have built practical international logistics and export experience through our used vehicle business. That experience underpins how we trade metals and industrial materials.
For custom specifications and deals that need flexibility — the kind larger houses struggle with — a responsible principal handles it directly, from spec check through shipment.
Copper cathodes and copper wire scrap as our core line, alongside other non-ferrous metals and raw materials.
Industrial petroleum and chemical products — base oil, urea (AdBlue / DEF), and lubricants.
One-stop execution: contracts, shipping documents, and transport arrangements.
Our core line. Substantial lots delivered with certificates of analysis and inspection records.

We also handle copper wire scrap (Millberry and other grades), serving smelting and brass mill demand. Destination, packing, and shipment schedule are arranged to your requirements.
