Shenzhen Boomtech Industrial Corporation — 4 prefixes (MA-L)

The vendor-shenzhen-boomtech-industrial slug consolidates four IEEE MA-L assignments registered to "Shenzhen Boomtech Industrial Corporation": B4:9A:95, 98:47:44, 88:0E:85, and 84:9D:4B, all carrying Bao'an District, Shenzhen, Guangdong, CN addresses (two slightly different building/street strings across the four rows, consistent with repeat-allocation address drift rather than distinct entities). The vendor's own English-language site (en.boomtech.cn) describes a company founded in 2004 that designs wireless-communication products, embedded software, and audio/IoT hardware/software modules; in 2020 it reorganized into five divisions (Semiconductor, Digital, IOT, Acoustics, Automated Test), and its stated core products are TWS Bluetooth headsets, "intelligent audio" control modules, and smart-wearable/smart-home/automotive-electronics modules. It is described as a national high-tech enterprise in China with IC-design-enterprise and "double soft" designations, and a 2022 "specialized and special new" (专精特新) enterprise award in Shenzhen. A device on a network carrying one of these OUIs is most plausibly a consumer Bluetooth-audio or IoT/smart-home peripheral built on a Boomtech-designed module, not networking infrastructure. A separate, similarly named registrant, "SHENZHEN BOOMTECH INDUSTRY CO.,LTD" (E8:07:BF, different Bao'an address), is excluded from this slug — the project's normaliseVendorName logic strips the differing "Corporation" vs "Co.,Ltd" suffixes to distinct base strings ("shenzhen boomtech industrial" vs "shenzhen boomtech industry"), producing separate slugs; treat it as a likely-related but administratively distinct registrant pending confirmation. No IEEE registration/allocation date exists for any of these prefixes — IEEE's the IEEE MA-L registry publishes no date field; third-party MAC-lookup aggregators (e.g. maclookup.app) show "registered" dates of 2019-03-19 (B4:9A:95), 2022-12-16 (98:47:44), 2024-10-24 (88:0E:85), and 2025-08-14 (84:9D:4B) that are database-ingestion artifacts, not IEEE facts, and are not recorded as allocation dates here.

Allocated date

Unknown [Confirmed] — IEEE the IEEE MA-L registry publishes no registration/allocation date for any of these 4 prefixes; third-party "date registered" values (maclookup.app: 2019-03-19 for B4:9A:95, 2022-12-16 for 98:47:44, 2024-10-24 for 88:0E:85, 2025-08-14 for 84:9D:4B) are database-ingestion artifacts, not IEEE facts

Security context

no vendor security-certification claims (e.g. IEC 62443, ISO 27001) found on the company's own site this pass — this is a consumer-electronics/embedded-module vendor, not an industrial-OT vendor [Likely — negative result] — https://en.boomtech.cn/, https://en.boomtech.cn/Company-Profile.html

CVE status

Unknown [Unknown] — no Boomtech-specific CVE or CISA ICS advisory located in this pass's web search; NVD/MITRE direct database query not performed. Absence of a search hit is not proof of absence.

Related vendors

SHENZHEN BOOMTECH INDUSTRY CO.,LTD (E8:07:BF) — same city/district, closely similar name, likely a related or predecessor/successor registrant, but administratively a separate IEEE registrant and a separate project slug (vendor-shenzhen-boomtech-industry); not merged into this entry pending confirmation

[Likely] — the IEEE MA-L registry

Analyst note

a globally-administered Shenzhen Boomtech Industrial Corporation OUI on a network most likely identifies a consumer Bluetooth-audio or smart-home/wearable peripheral built on a Boomtech-designed embedded module — not networking or industrial-OT hardware. Do not surface a third-party "registration date" as an IEEE fact.
