The three reasons buyers switch suppliers.
And what we do differently.
Weeks to get a reply
International offices in London and Hong Kong. Same-day responses in your timezone.
"30 days" that becomes 6 months
Conservative scheduling. Real timelines quoted upfront, not after you commit.
Export regulation surprises
MOFCOM licensing starts day one, runs parallel with production.
The 3 Pillars
Engineered to Your Exact Specifications
We handle challenging projects that commodity suppliers can't.

Engineered to Your Exact Specifications

How We Actually Work
Why Mainrich?
We deliver what we quote, when we quote it, and we pick up the phone when things get complicated.
Same company, same owners, 30 years running.
We're not a trading company that appeared last year and might disappear next year. Four owned factories across Guangdong, Zhejiang, and Liaoning. UK and Hong Kong offices you can actually visit. When regulations change, we adapt - we don't run.
→ You will always know who to call


We quote 30-45 days. We deliver in 30-45 days.
That sounds like it should be the bare minimum. But after talking to enough buyers who were promised 30 days and waited 6 months, we know it's not. Our production scheduling is conservative on purpose. If there's a risk of delay, we tell you before you place the order - not three months in.
→ Honest timelines, not optimistic ones
Factory direct. No distributor markup.
Vertically integrated across four production sites. Sintering, machining, coating, magnetization, QC - all in-house. You're buying from the people who actually make the magnets, not a middleman adding 20% for a PDF with your logo on it.
→ Competitive China pricing without the China risk
