BiLock started the UL evaluation process years ago when it was owned by the Australian Lock Company. The evaluation was still in early stages when the BiLock brand was acquired by BiLock North America. The new owners elected to focus their resources on broadening the product line and relaunching the brand, rather than restarting the UL process.
I'll be honest when I say I wasn't expecting BiLock to be as open and responsive as they were, and was pleasantly surprised. I'd encourage others in the community to reach out to manufacturers politely as well if you have questions, and perhaps we can improve the overall relationship between the two parties.
