Hosin Global Electronics Co., Ltd. — 2 prefixes (MA-L)

A MAC address starting with 8C:37:B7 or 2C:3E:BF belongs to Hosin Global Electronics Co., Ltd., a Shenzhen-based NAND flash storage and memory manufacturer, typically seen on embedded storage hardware such as SSDs, eMMC/UFS modules, DRAM modules, or USB flash controllers rather than on a classic network interface card.

IEEE's the IEEE MA-L registry lists two MA-L (24-bit) blocks at the same Futian District, Shenzhen facility, filed under slightly different name and address text: "Hosin Global Electronics Co.,Ltd" for 8C:37:B7 and "HOSIN Global Electronics Co., Ltd." for 2C:3E:BF. No MA-S or MA-M block was found for this company.

Hosin Global is an identifiable, currently operating company that designs and sells SATA/PCIe SSDs, embedded flash (eMMC/UFS), DRAM/DDR4/DDR5/LPDDR modules, and USB flash drives, and states it develops its own storage controller ICs. It is listed as a Chinese "National High-Tech Enterprise," exhibits at MWC Barcelona, and appears on a WPG Holdings distributor line card, all consistent with an active B2B electronics-component business rather than a dormant OUI registration.

A separate, unrelated company named "Hosin Industrial Limited" holds a sub-block, 70:B3:D5:69:2/36, under the shared IEEE base 70:B3:D5. That shared base is administered by IEEE and sub-allocated to roughly 4,092 registrants; it does not belong to Hosin Global Electronics and should never be cited as this vendor's territory.

Independent corroboration comes from a USB-IF Vendor ID, 0x325D, registered to the same legal name and tied to a named product, "2319 Boot ROM" — consistent with the HG2319-series controller chip Hosin Global markets. No source ties either OUI specifically to a shipping networked, Wi-Fi, or Bluetooth product, so device-level attribution beyond "Hosin Global hardware" stays unconfirmed.

Verified sample prefixes

8C:37:B7, 2C:3E:BF (both MA-L, Hosin Global Electronics) [Confirmed] — the IEEE MA-L registry 8C37B7, 2C3EBF

Unrelated shared-base entity

70:B3:D5 is an IEEE-administered shared base with roughly 4,092 registrants; sub-block 70:B3:D5:69:2/36 belongs to a different company, "Hosin Industrial Limited" — not this vendor [Confirmed] — the IEEE MA-S registry 70B3D5692

Special note

No IEEE registration date exists for either block; IEEE's the IEEE MA-L registry schema has no date column. maclookup.app prints third-party "Initial registration" dates (2C:3E:BF = 04 Mar 2023, 8C:37:B7 = 20 Jan 2026) that are database artifacts, not IEEE facts

[Confirmed] — the IEEE MA-L registry 8C37B7, 2C3EBF

Related vendors

none confirmed; Hosin Industrial Limited is NOT confirmed related (different legal entity, different registered address) [Unknown] — the IEEE MA-S registry 70B3D5692

Analyst note

two independently-addressed OUI blocks plus an independent USB-IF VID tied to a named chip product indicate a real operating company, not a shell registration; no source ties either OUI to a shipping networked/Wi-Fi/Bluetooth device, so treat matches as Hosin Global hardware, likely embedded storage, rather than a classic NIC
