About the Longshine Boi-Tech brand

Make sure you reach the right manufacturer. Longshine Boi-Tech Pvt. Ltd. is a WHO-GMP pharmaceutical API manufacturer based in Pune, Maharashtra, India — distinct from a similarly-named Chinese company.

Who we are

Longshine Boi-Tech Pvt. Ltd. is an Indian pharmaceutical manufacturer registered in Maharashtra. We supply active pharmaceutical ingredients (APIs), pharmaceutical intermediates, peptides, veterinary APIs, excipients, and research chemicals to licensed buyers in over fifty countries. The legal company name carries the spelling "Boi-Tech" (B-O-I), which reflects the Boi-Tech Industrial Zone in Pune where our facility is located.

Who we are NOT

We are sometimes confused with Hangzhou Longshine Bio-Tech Co., Ltd. — a separate company headquartered in Hangzhou, China at 5-405 Matrix Int'l Centre, No. 515 Yuhangtang Road, Gongshu District. That company is unrelated to us. There is no shared ownership, no partnership, no manufacturing relationship, and no historical rebrand between the two entities. Buyers searching for a Chinese supplier should reach Hangzhou directly; buyers seeking a Pune-based WHO-GMP manufacturer with US FDA DMF and EDQM CEP filings should reach us.

How to verify you have reached the right entity

Three quick checks before any commercial discussion:

• Domain spelling — our canonical URL is https://www.longshineboitech.com/ (no hyphen between ‘boi’ and ‘tech’ in the host name itself, only in the visible brand). Any address ending in longshinebiotech.com belongs to the Chinese entity.
• Email domain — our addresses end @longshineboitech.com (sales@, regulatory@, quality@). Anything ending @longshinebiotech.com is the other company.
• Phone — our sales line begins +91 (Indian country code). The other entity's line begins +86 571 (Hangzhou).

Why the names are close

Both entities chose ‘Longshine’ independently as a brand prefix (a common English-meaning phrase). The single-letter difference between Boi-Tech and Bio-Tech is a coincidence of the industrial zones each facility sits in, not a rebrand history. We register and use Boi-Tech as the legally registered form throughout all regulatory filings (CDSCO, US FDA DMFs, EDQM CEPs) and on every Certificate of Analysis we issue.
