Warranty Return Policy

Our Quality Commitment

Every blade that leaves our facility in Ezhou City has passed final outgoing inspection — dimensional checks, visual inspection, runout measurement, and cutting performance testing on sample pieces from each production run. We stand behind that process. If a blade fails under normal operating conditions within the warranty period, we will replace it or issue credit. That's the short version.

The longer version is below, because diamond saw blade warranty involves specifics that matter to your business: what's covered, what isn't, how to submit a claim, and how long the process takes. Read it once and you'll know exactly where you stand.

Warranty Coverage

Duration

CLSEG warrants its diamond saw blades against manufacturing defects for a period of 12 months from the date of confirmed shipment, or until the segment reaches the end of its usable life, whichever comes first.

Segment wear is a normal part of using a diamond blade — the warranty covers defects in the blade itself, not consumption of the cutting segment through normal use.

What Is Covered

Segment Separation or Detachment

Welding joint failures where the blade was used within its rated RPM, compatible with the material specified, and operated with adequate cooling where required.

Premature Segment Loss

That cannot be attributed to incorrect application, overloading, or improper machine mounting — verified through returned sample inspection.

Core Deformation or Cracking

That is not the result of impact, improper storage, or use beyond the blade's rated specifications.

Dimensional Non-Conformance

On delivery: diameter, arbor bore, thickness, or segment geometry that deviates materially from the confirmed order specification.

Manufacturing Defects on Delivery

Identified before first use, including visible welding defects, surface cracks in the steel core, or incorrect labeling on OEM/private-label orders.

What Is Not Covered

We've been making diamond blades since 2003 and we've seen every failure mode there is. Most claims that don't qualify come down to application mismatch — a blade spec'd for marble cutting used on hard abrasive granite, or a wet-cut blade run dry. The following are not covered under this warranty:

Normal Segment Wear

Diamond blades are consumable cutting tools; depletion of the segment matrix through use is expected, not a defect.

Incorrect Application

Using a blade rated for a specific stone type or hardness range on an incompatible material.

Wet/Dry Mismatch

Dry cutting with a wet-cut blade — or wet cutting with a dry-cut blade; the thermal stress and water ingress implications are different by design.

Operating Beyond Rated RPM

Running a blade above its maximum RPM marking creates centrifugal stress the core was not designed for.

Improper Mounting

Using an arbor size other than specified, or inadequate flange support on large-diameter blades.

Impact Damage

Dropping a blade, forcing it through a material, or kickback events.

Improper Storage

Corrosion, core deformation, or segment degradation caused by moisture exposure, stacking heavy items on blades, or storage in chemically corrosive environments.

Modified Blades

Grinding, regrinding the segments, or altering the core after delivery.

Force Majeure

Natural disaster or force majeure events during transit or storage.

Returns & Eligibility

Return Policy

Clear conditions for when returns are accepted, what state the product must be in, and who bears freight cost.

Eligibility Window

Returns are accepted within 30 days of the shipment date for:

Blades with manufacturing defects confirmed before first use
Order errors on our side — wrong specification, wrong quantity, wrong labeling versus the confirmed purchase order
Blades with dimensional non-conformance identified on delivery inspection

Returns are not accepted for:

Used blades (blades with visible cutting use), except in the context of a warranty claim for in-use defects (see Warranty Claims process below)
Products returned outside the 30-day window without prior written agreement
Custom OEM or ODM orders unless the issue is a manufacturing defect or order error — custom-spec blades are produced to your confirmed specification and cannot be returned due to a specification change on your end

Return Condition Requirements

Returned blades must be:

In their original packaging where possible, or packaged to prevent damage in transit

Accompanied by the original packing list or invoice reference

Unused (for pre-use defect or order error returns), or clearly documented with the usage conditions and failure description (for warranty claims)

Who Pays Return Freight

Reason for Return	Return Freight
Manufacturing defect confirmed by CLSEG	CLSEG covers return freight or issues credit without requiring physical return for low-value claims
Order error on CLSEG's side	CLSEG covers return freight
Buyer specification error or change of mind	Buyer covers return freight
Warranty claim (in-use defect, under investigation)	Buyer covers inbound freight; CLSEG covers outbound replacement freight if claim is approved

Overseas shipments: We often process warranty replacements or credits without requiring the full returned quantity to ship back — the freight cost on a container of blades doesn't make sense for either side. We'll ask for a representative sample and photographs instead.

Claims Process

How to Submit a Warranty Claim or Return Request

Follow these four steps to get your claim reviewed and resolved as quickly as possible.

Contact Us First

Email or message us before returning any product. We need to review the claim before any goods move.

Provide Documentation

We'll ask for the following to evaluate your claim:

Your original purchase order number or invoice reference
Photographs of the affected blades — full blade, segment detail, core (if relevant), and any visible damage or failure point
Description of the application: stone or material type, machine make and model, operating RPM, wet or dry cut, approximate footage cut before failure
The quantity affected versus the total quantity received in the same shipment

We Review and Respond

Our QC team reviews the documentation and gets back to you:

3–5 days

Straightforward cases — dimensional non-conformance on delivery, pre-use defects

Up to 10 days

In-use warranty claims requiring detailed review, especially where application conditions need verification

Resolution

Approved claims are resolved by one of the following, at CLSEG's discretion based on the nature and scale of the issue:

Replacement blades shipped with your next order or as a standalone shipment
Credit note applied to your account for future orders
Partial replacement or partial credit where only a portion of the claim is confirmed

No Cash Refunds on International Orders

We don't issue cash refunds on international orders. Resolution is by replacement or credit. This approach keeps the process practical for both sides on cross-border transactions.

Buyer Responsibility

Inspection on Receipt — Your Responsibility

We strongly recommend inspecting all shipments within 5 business days of delivery. For container loads:

Verify Quantities

Check the packing list against actual quantities received. Confirm piece counts per SKU and per carton where applicable.

Sample Inspection

Inspect a representative sample of blades for visible defects, dimensional issues, or packaging damage.

Document Discrepancies

Note any discrepancies on the delivery documentation and photograph them. Clear records expedite claim resolution.

Report Within 5 Days

Report any issues to us within 5 business days of receipt. Timely notification allows us to trace logistics and production records while still fresh.

30-Day Reporting Window: Claims for shortage, wrong goods, or visible damage reported after 30 days from shipment will be reviewed at our discretion. We're not trying to create a window to avoid responsibility — we're asking for timely notification so we can address issues with our own logistics and production records while they're still traceable.

Legal Scope

Limitations

To the extent permitted by applicable law, the following limitations apply to all warranty obligations and liability:

Liability Cap

CLSEG's liability under this warranty is limited to replacement of the defective product or issuance of a credit note equal to the invoice value of the affected goods. We are not liable for consequential losses, downtime costs, third-party claims, or project delays arising from product defects.

Specification Authority

Product specifications shown on our website and in our catalog are for reference. Final product specifications are those confirmed in writing in the purchase order and order acknowledgment.

Non-Transferable

This warranty applies to the original purchaser only and is not transferable to downstream buyers or end users.
