Service Tenet
We are committed to providing fair and thoughtful after-sales support for customers
of authorized channels worldwide. We will respond to your needs at the first time to
ensure your peace of mind when using Chang cymbal products. Core Warranty Rules
Brand-new genuine cymbals purchased from authorized Chang dealers are covered
by a two-year warranty starting from the date of purchase. The warranty applies to
damages incurred under normal use (damages caused by human factors, improper
use, natural oxidation, impact, modification and other such circumstances are not
covered by the warranty). To apply for the warranty, valid purchase documents such
as invoices, official order records or purchase certificates from dealers must be
provided. No official warranty is provided for accessories including cymbal bags, cymbal stands
and drumsticks. Second-hand products, rental inventory products and products
purchased from unauthorized channels are all not eligible for this warranty service.
After-sales Inspection and Evaluation Standards
To accurately determine whether cymbals meet the replacement criteria, we will
conduct inspections from the following dimensions, while taking into account the
particularity of usage scenarios:
(I) Verification of Purchase Date
A copy of the purchase document must be provided to confirm the purchase date and
dealer information. (II) Damage Criterion
1. Edge Damage (Non-performance-related Human-caused Damage)
Inspect whether there are chips, chisel marks or rough areas on the edges caused by
falling or collision; cracks often extend from such damaged areas or the bell area of
the cymbal. 2. Inspection of Center Hole Condition

Over-tightening of the stand will restrict the vibration of the cymbal, leading to stress
cracks, metal bending or dents; such damages may also result from excessive
playing or mismatched specifications. 3. Inspection of Wear Caused by Improper Installation
• Damaged/missing stand protectors → Corrosion in the center hole area;
• Missing/severely worn felts → Corrosion marks on the inner/top surface of the
cymbal’s bell area. Normal Wear: Slight minor wear and a smooth surface are normal phenomena;
annular metal corrosion is a clear sign of improper use. Supplementary Note on Appearance Craft Traces
Small pits, spots and hairline marks on the cymbal surface are natural residues of
metal impurities during hand forging, which are inevitable normal craft phenomena.
If such traces develop into cracks within the warranty period and there are no signs
of improper use, the damage is covered by the warranty.
Pure appearance traces without cracks will not affect the use and shall not serve as a
basis for after-sales claims. (III) Principles for Determining Warranty Eligibility
1. Core Principle: If a cymbal has no traces of non-performance-related
damage/abuse, is in good overall condition except for cracks, and is still within the
warranty period, the above characteristics will be confirmed through inspection, and
the cymbal will be handled in accordance with the warranty policy (e.g., replacement
with a product of the same specification).
2. Non-warranty Handling: Damages caused by falling, collision, excessive playing,
improper installation, non-manufacturing defects and other such reasons are not
covered by the warranty. Warranty Application Process
1. Initiate the Application: Contact the authorized dealer where the purchase was
made or our official customer service through the background of the official website
(www.changcymbals.com) to submit after-sales demands..
2. Prepare Materials: Provide the following three types of materials:
• Clear photos/videos of the damaged cymbals (all damaged areas must be fully
displayed); • A copy of the original purchase document;
• Contact information and purchase details of the individual/dealer.
3. Audit and Feedback: We will complete the audit and reply within 5 working
days, and inform the follow-up inspection and handling arrangements simultaneously.

4. Return for Inspection: After the audit is approved, send the damaged cymbals to

requirements). Chang Cymbals shall bear the shipping cost for the delivery of
the replaced cymbals. If any customs duties are incurred, the customer shall be
responsible for their payment.
