Returns & Refund Policy
Last updated: October 2026
All sales are final. We do not accept returns, exchanges, or refunds on any product in our store. Please review your order carefully, including model, specifications, and quantity, before purchasing.
Warranty terms for each product category are set out below.
1. Grinding Wheels (Diamond and CBN)
Grinding wheels are custom-made to your specifications. They are not eligible for return, exchange, refund, or warranty claims under any circumstances. Please verify all specifications (dimensions, grit, bond, concentration, etc.) carefully before confirming your order.
2. Solenoid Valves
Warranty. Solenoid valves are covered by a one-year warranty from the date of delivery against manufacturing defects.
Claims. Email tanya@zyindustrial.com with your order number, a description of the problem, and photos or video showing the defect. We will review the claim and determine whether it is a manufacturing defect.
Remedy. If we confirm a manufacturing defect, we will send a replacement unit at our cost. The defective unit does not need to be returned unless we request it. One replacement per original unit.
Not covered. The warranty does not apply to failures caused by:
- incorrect voltage or wiring;
- contaminated or chemically incompatible media;
- pressure or temperature outside rated specifications;
- coil overheating due to continuous-duty operation beyond the rated duty cycle;
- improper installation, misuse, impact, or unauthorized disassembly or repair;
- normal wear of seals, diaphragms, O-rings, and coils after use.
Solenoid valves damaged by any of the above causes are not eligible for replacement.
3. Mitutoyo and Other Precision Instruments & Gauges
Warranty. These products are covered by a one-year warranty from the date of delivery against manufacturing defects. The warranty provides repair or replacement only. It does not provide a refund.
How to make a warranty claim
- Email tanya@zyindustrial.com with your order number, the product serial number (where applicable), a description of the problem, and photos or video.
- We will provide the return address of the service center. Do not ship anything before receiving this address from us in writing. Unauthorized shipments will not be accepted.
- Ship the product to that address. The buyer is responsible for shipping costs to the service center, including any export fees, customs duties, and taxes. Please keep the original packaging and accessories and include them where possible.
- Return the same unit that was purchased. The unit is identified by its serial number where applicable, or by model number and our purchase records. Units that do not match will not be accepted.
Return shipping after repair. If inspection confirms a manufacturing defect covered by this warranty, we will cover the cost of shipping the repaired or replacement unit back to the buyer, using the carrier and service level of our choice. Import duties and taxes at destination remain the buyer’s responsibility.
Damage not covered by warranty. The warranty is void if inspection determines that the damage was caused by misuse, impact, dropping, liquid or coolant ingress, improper installation, unauthorized disassembly or repair, or normal wear. In this case:
- where repair is possible, a paid repair may be offered at the buyer’s expense;
- where repair is not possible, the item will be returned as-is or scrapped, at the buyer’s choice;
- all shipping costs in both directions are borne by the buyer.
Consumables (such as batteries) and wear parts are not covered by the warranty.
