This product is a high-purity natural agate grinding ball, primarily composed of silicon dioxide (SiO₂) ≥ 99.91%, with extremely low impurity content, ensuring high grinding purity. The spheres are precisely polished, resulting in a smooth surface and high sphericity, making them suitable for a wide range of laboratory ball mills and grinding equipment. Their high hardness and wear resistance effectively reduce cross-contamination during grinding, ensuring sample purity and experimental reproducibility.

Yes. We offer CNC machining, ceramic injection molding, cold isostatic pressing, hot pressing, dry pressing and casting to produce non-standard parts based on your drawings or samples.
Different products have different MOQ, if you have mass production in future, we can discuss MOQ again to meet your requirement.
Our products meet ISO 9001:2015 and IATF16949 standards. Material COA (Certificate of Analysis) and mechanical test reports (e.g., hardness, density, flexural strength) are available.
Standard tolerance is ISO2768-M. Precision machining can reach ±0.001mm (depending on material and design).
Standard parts: 1-7 days; Custom parts: 30-60 days (complex designs require additional evaluation).
We use two or three layer protection: shock-absorbing foam + reinforced cartons or shock-absorbing foam + individual blister boxes + reinforced cartons. Fragile labels are applied for delicate parts.
Yes. Provide your application conditions (temperature/medium/pressure/load), and our engineers will recommend the optimal material solution.
Report the issue within 7 days with photos/videos. Verified defects will be replaced or refunded at no cost.
Yes. Contact our email info@innovasupplies.com to get more details about offline orders. For corporate transfers, provide full company name and tax ID for VAT invoice issuance.
Yes, for large orders, we can discuss by offline through email.
Returns are accepted if:
– Received incorrect product model/specification
– Manufacturing defects (non-human damage)
– Unopened packaging & resalable condition (standard parts only)
Claims must be filed within 7 business days after delivery.
Custom orders are non-returnable (unless with critical defects) as they are produced specifically for you. Pre-shipment inspection reports will be provided for approval.
Tours by appointment only. Submit 3 days in advance: company name, visitor position, purpose. Note: Clean-rooms require protective gear.
If you have mass production in future, 1-5 free standard samples are available and you pay the freight cost, custom samples charged at cost.
Import duties, customs taxes and carrier brokerage fees are charged by customs authorities or the carrier when an international shipment enters your country. These charges are not set or collected by InnovaSupplies at checkout unless DDP shipping is explicitly specified.
Unless DDP shipping is explicitly specified, international orders are shipped under DAP terms. This means the buyer is responsible for paying any import duties, customs taxes, brokerage fees, storage fees, or other customs clearance charges after the shipment arrives.
If customs charges are not paid on time, the shipment may be delayed, returned, stored, or abandoned. Any resulting shipping, return, storage, customs, or handling costs will be the buyer’s responsibility. Refund eligibility may be reduced or denied for custom-made or non-resellable products.
