Supplier sourcing & verification
Give us your specification. We shortlist three to five factories, audit them in person, and return comparable quotes with lead times — before you pay anyone.
How sourcing worksZhengzhou · China’s superhard materials hubDiamond tools from China,
Diamond tools from China,
sourced and inspected
by people who live where they’re made.
More than 90% of the world’s synthetic diamond is produced within three hours of our office. We turn that geography into factory-direct pricing, independent inspection, and one invoice for your entire order.

What we do
Four things, done properly.
We are not a marketplace and we are not a freight forwarder. We are the party that knows which factory to call, what the price should be, and how to prove the goods are right before they leave China.
Quality inspection
Pre-shipment inspection with dimensional reports, hardness and bond testing, and photo evidence on every order — not only when something goes wrong.
What we checkConsolidation & warehousing
Buy from five factories, receive one shipment. We hold, label, palletise and photograph everything in our Zhengzhou warehouse before it moves.
Consolidation detailFreight & logistics
Rail to Europe in 12–18 days, air to North America in five, sea freight for heavy tonnage. Customs paperwork and export declarations included.
Routes & transit timesWhy Zhengzhou
The world’s diamond tool supply chain already runs through Henan.
Most sourcing agents sit in Shenzhen or Yiwu and buy diamond tools from traders. We sit where the material is synthesised, the powder is graded and the bonds are sintered.
- 90%+ of global synthetic diamond is produced in Henan province, concentrated around Zhengzhou and Nanyang.
- Three hours by high-speed rail to every major manufacturing belt we buy from — no flights, no excuses, same-week factory visits.
- Direct rail freight to Europe from Zhengzhou terminal — 12 to 18 days door to door, roughly half the cost of air.
- Zhengzhou Xinzheng airport is a cargo hub with daily freighter capacity to Europe and North America.
What buyers usually get wrong
How it works
Six steps. No black boxes.
You always know which stage your order is at, who is handling it, and what happens next.
01
Send the specification
Drawing, sample photo, or just a description of what the tool has to do. We will tell you what information is still missing before quoting.
02
Shortlist and quote
Within five working days you get three to five comparable factory quotes, with lead times and the trade-offs between them spelled out.
03
Sample and approve
We arrange samples, test them against your spec, and only release production once you have signed off on the reference piece.
04
Production and inspection
We monitor the run and inspect before shipment — dimensions, hardness, bond integrity, packaging. Report and photos go to you.
05
Consolidate and ship
Goods from multiple factories are merged into one shipment, labelled to your warehouse requirements, and moved on the route you choose.
06
After-sales
If something is out of specification, we handle the claim with the factory on your behalf. You deal with one contact, not five.
What we source
Superhard materials, end to end.
From micron-sized diamond powder to finished core bits. If it cuts, grinds or polishes hard material, it probably comes from Henan.
Cutting
Diamond cutting tools
Segmented blades, turbo blades, laser-welded discs for granite, concrete and tile.
DrillingDiamond core drills
Wet and dry core bits, 20–400 mm, for reinforced concrete and masonry.
GrindingDiamond grinding wheels
Resin, metal and vitrified bond wheels for carbide, glass, ceramics and PCD.
MaterialSuperabrasive powder
Micron diamond, CBN and coated grit, graded to your mesh and concentration.
Pricing
One number, written down before you commit.
Sourcing agents who won’t tell you their commission are usually charging you in the factory price. We publish ours.
- Charged on product value only — never on freight, never on inspection
- Factory quotes shown to you at cost, with the factory name
- No minimum order value — a single carton is fine
- Inspection and consolidation included, not billed as extras
Standard commission
5%of product value
On a US$20,000 order that is US$1,000 — and the factory price you see is the price the factory quoted us. For high-volume or repeat programmes the rate is negotiable downward.

Our commitments
Three things we put in writing.
Transparent pricing
You see the factory quote and our commission as separate lines. If a factory raises its price mid-programme, you see that too.
Inspection before payment clears
We inspect and report before the balance payment is released to the factory. Nothing ships on a promise.
One named contact
The person who quotes your order is the person who answers during production. No ticket queues, no handoffs to a call centre.
Questions
Answered before you ask.
A flat 5% of the product value. Freight, inspection and consolidation are quoted separately at cost — we do not mark them up. There is no retainer and no fee to submit an enquiry.
No. We regularly handle orders of a few cartons for buyers validating a supplier before scaling. The 5% commission simply applies to whatever the order is worth.
Yes. That is the default arrangement. Production typically runs on a 30% deposit, and we inspect and send the report before the 70% balance is released. If the goods fail, the balance does not go out.
China–Europe rail: 12–18 days door to door. Air to North America: 5–8 days. Sea freight: 30–40 days depending on port. Transit times are quoted per order, based on the actual route at the time of booking.
Most of our clients started as small buyers. The economics work the same at any volume because the commission is percentage-based, and consolidation means you are not paying for a container you cannot fill.
We raise the claim with the factory, negotiate replacement or credit, and handle the paperwork. Claims are far rarer when inspection happens before shipment rather than after arrival — which is the whole point.
An agent. We do not hold inventory or resell goods at a hidden margin. We are paid a stated commission to find, verify and manage factories on your behalf — which means our incentive is a repeat order, not a one-time markup.
