1. Scope

This policy applies to all custom cardboard displays, display boxes, and related packaging products sold by Long Win Display Shenzhen Limited (“we”) via www.longwindisplay.com.

2. Sample Approval Policy
 

• Before mass production, we strongly recommend and usually require customers to approve a sample (Golden Sample).

• Mass production will be based solely on the final sample approved by the customer via signature or email confirmation, including structure, dimensions, material, printing content, color effect, and surface finishing.

• If the customer proceeds directly to mass production without requesting a sample, it is deemed acceptance of “production according to customer-provided files,” and color/structure deviations not caused by quality issues will not be grounds for return or exchange.

3. Color and Physical Tolerance
Given that cardboard displays are custom consumables affected by printing processes, paper batches, and transportation conditions, the following tolerances are considered acceptable within the industry:

    • Printing color: Based on Pantone or CMYK references, a color difference of Delta E < 5 is considered within normal tolerance.

    • Paperboard thickness: A thickness variation of ±5% within the same batch is acceptable.

    • Load-bearing performance: Under correct assembly and usage, load capacity shall meet the testing standards confirmed by both parties (e.g., ISO or industry-common methods).

Deviations beyond the above ranges that affect normal use may be considered quality disputes.

4. Quality Dispute Window and Evidence Requirements
• Inspection period: Customers must complete visual and functional inspection within 15–30 days after receipt of goods.

• In case of serious issues (e.g., load-bearing collapse, obvious printing errors, inability to assemble normally, etc.), a written claim (via email) must be submitted within the inspection period, including:

     • Clear photos or videos of the issue (including overall and close-up views);

     • Order number, date of receipt, and affected quantity;

      • If available, third-party inspection reports or logistics damage certificates.

Claims not raised within the inspection period will be deemed as acceptance of the goods as delivered and qualified.

5. Responsibility Allocation

5.1 Transit Damage
 

• For transit-related outer carton damage, moisture, or obvious dents, if damage certificates from the logistics provider or clear photo/video evidence are provided, we will assist the customer in claiming compensation from the logistics carrier and, depending on the situation, offer replacement or discount solutions.

• Customers must notify the logistics provider immediately upon receipt or upon discovery and retain relevant evidence.

5.2 Manufacturing Defects
 

• For quality issues confirmed to be caused by our production errors (e.g., severe printing errors, material mismatch, structural failure to bear load, etc.), we will:

    • Replace the affected portion or the entire batch free of charge (depending on severity and quantity); or

    • Upon mutual agreement, provide a credit or refund of the corresponding amount.

• The amount of replacement or refund shall be capped at the order value of the defective goods and does not cover indirect losses (e.g., promotional delays, sales losses, etc.).

5.3 Customized Products Without Quality Issues
 

• All displays are custom-made consumables. Once produced, returns or exchanges due to “slight color deviation,” “subjective dissatisfaction,” or “order cancellation” will not be accepted unless there is a quality issue.

• Issues caused by customer file errors, approval draft mistakes, or late modification requests shall be borne by the customer.

6. Refund Process
 

• When a refundable situation is confirmed by both parties, we will arrange the refund or credit within 5–10 working days.

• Refunds will, in principle, be returned via the original payment method; if this is feasible, both parties may agree on other reasonable methods (e.g., credit toward future orders).
