Quick Answer

Buy diamond tools from China by verifying the factory, matching tools to your concrete and machines, requesting samples before bulk, and agreeing terms in writing. The risks are quality inconsistency and wrong bond specification - both are solved by testing samples.

Step 1: Verify the Supplier

• Check the factory's export records and business registration
• Ask for photos of the production line, not just the showroom
• Request references from buyers in your market
• Confirm which standards they test against

Step 2: Match the Product to Your Job

Send the supplier your concrete hardness, machine brand and holder type. The bond and plate style must match: trap-style, Redi-Lock or brand-specific. A good supplier recommends the bond, not just the cheapest price.

Step 3: Order Samples First

Buy a small test set covering the grits and bonds you plan to use, run them on a real job, and measure cut rate, wear and finish. Compare two or three suppliers side by side on the same floor.

Step 4: Agree Commercial Terms in Writing

• MOQ and sample cost
• Bulk pricing and lead time
• Payment terms and Incoterms
• Quality claims, batch consistency and what happens on defects

Step 5: Plan the Import

Confirm packaging for fragile diamond tools, shipping time and documentation. Ask for photos before dispatch and keep samples from the approved batch for comparison when goods arrive.
