For stone tool distributors and regional wholesalers, OEM diamond polishing pads represent one of the highest-margin product categories available — if you source correctly. The difference between a profitable OEM program and an expensive mistake comes down to three variables: factory capability, minimum order quantity, and brand customization depth. This guide covers all three.
What OEM Actually Means for Diamond Polishing Pads
In the diamond tool industry, "OEM" (Original Equipment Manufacturer) means the factory produces pads to your specifications and ships them under your brand. This is distinct from:
- White-label: Standard stock pads with your logo printed on the backing — no formula changes.
- ODM (Original Design Manufacturer): The factory designs the product; you brand it.
- True OEM: You specify the diamond concentration, bond hardness, grit sequence, and Velcro backing — the factory manufactures to your spec.
Most distributors start with white-label and graduate to true OEM as volume increases. Both are viable; the right choice depends on your order volume and how differentiated you need your product line to be.
What Can Be Customized
1. Diamond Concentration Grade
This is the most impactful variable. Higher diamond concentration (measured in carats per cubic centimeter of bond matrix) means longer pad life and faster cut rate — but also higher cost. A reliable factory can tell you the exact concentration grade for each SKU. If they can't, they're reselling generic stock.
For professional-grade distributors targeting fabrication shops, specify a minimum concentration of 40–50 carats/cm³ for resin bond pads. Budget-grade pads typically run 20–30 carats/cm³.
2. Resin Bond Formula
Bond hardness determines which stone types the pad performs best on:
- Soft bond: For hard stone (granite, quartzite) — the bond releases diamonds faster, maintaining cut rate.
- Hard bond: For soft stone (marble, limestone) — prevents premature diamond loss on softer surfaces.
- White resin bond: Non-staining formula for light-colored stone (Carrara marble, white quartz) — critical for high-end fabrication shops.
3. Velcro Backing Color
Velcro color is the most visible brand differentiator. Standard colors are black and white; custom colors (blue, red, orange) are available at higher MOQ. Color-coding by grit is a popular strategy for distributors — it reduces operator error on job sites.
4. Logo and Packaging
Logo printing on the pad backing is standard for MOQ 500+ pieces per SKU. Custom retail packaging (blister packs, branded boxes) is available at MOQ 1,000+ pieces per SKU.
OEM Diamond Polishing Pads for Quartz & Tile
Quartz and porcelain tile are the two fastest-growing segments in stone fabrication — and both require specialized diamond polishing pads. Standard granite pads run too hot on quartz and wear too fast on tile. OEM programs for quartz polishing pads and tile polishing pads require specific bond formulations:
- Quartz: Heat-sensitive engineered stone. Requires wet diamond polishing pads with ultra-soft resin bond and strict RPM control (max 3,000). Standard pads can scorch quartz within seconds. Custom OEM quartz pads use a low-temperature bond formula and increased diamond concentration to compensate for the lower RPM.
- Porcelain & Ceramic Tile: Harder and more abrasive than natural stone. Requires diamond polishing pads with a harder resin bond and higher diamond concentration. Tile polishing pads in OEM programs typically start at 200 grit (tile doesn't need coarse grinding) and run through 3000 grit for edge polishing and surface restoration.
For distributors targeting countertop fabricators who work with quartz and large-format porcelain slabs, a combined OEM program covering granite + marble + quartz + tile covers 95% of a fabrication shop's pad consumption. Contact KAIYI for quartz and tile OEM sample kits.
MOQ and Lead Times
| Program Type | MOQ | Lead Time | Customization |
|---|---|---|---|
| White-label (stock pads + logo) | 10 pcs/SKU | 3–5 days | Logo on backing only |
| Semi-custom (color + logo) | 100 pcs/SKU | 2–3 weeks | Velcro color + logo |
| Full OEM (custom formula) | 500 pcs/SKU | 4–6 weeks | Full spec customization |
| First OEM order (new formula) | 500 pcs/SKU | 6–8 weeks | Includes formula development + testing |
Lead times above assume raw material availability. For orders placed during Chinese national holidays (Golden Week in October, Chinese New Year in January/February), add 2–3 weeks.
How to Vet a Factory for OEM
Request a Technical Data Sheet
A legitimate manufacturer can provide a TDS for each pad SKU, including diamond concentration, bond hardness rating, recommended RPM range, and compatible stone types. Trading companies cannot produce this document because they don't control the manufacturing process.
Ask for a Sample Run Before Full Order
Any factory confident in their product will provide samples (typically 5–10 pieces per grit) before you commit to a full OEM run. Test samples on your target stone types under real working conditions — not just a quick pass on a scrap piece.
Verify Production Capacity
For distributors placing orders of 5,000+ pieces, confirm the factory's monthly production capacity. A small operation running 2–3 presses cannot reliably fulfill large orders on schedule. Ask for photos of the production floor and sintering equipment.

FAQ
What is the minimum order for OEM diamond polishing pads?
Our white-label program starts at 10 pieces per SKU — the lowest MOQ in the industry for branded diamond pads. Full formula customization (custom bond hardness, diamond concentration) requires a minimum of 500 pieces per SKU with a 6–8 week lead time for the first production run.
Can I specify the diamond concentration for my OEM pads?
Yes. We can produce pads at specific diamond concentration grades to match your target market — from economy-grade (20–30 carats/cm³) to professional-grade (40–50 carats/cm³). We provide a technical data sheet for each custom SKU confirming the specification.
Do you offer free samples before an OEM order?
Yes. We provide sample sets (5–10 pieces per grit) for evaluation before any OEM commitment. Shipping cost applies for international sample shipments. Contact us to arrange a sample kit for your target stone types.
