Effective Date: [February 4th, 2026]
This Warranty Policy (“Policy”) applies to eligible purchases made on ADVINCI.shop (“ADVINCI,” “we,” “us,” or “our”). By placing an order on ADVINCI.shop, you agree to this Policy.
This Policy applies only to orders purchased directly from ADVINCI.shop.
If you purchased through another retailer or platform (including, without limitation, Amazon or authorized dealers), that retailer/platform is responsible for warranty and after-sales service under its own policies. ADVINCI.shop does not process warranty claims for such orders.
We currently sell two major product categories. Fulfillment methods and after-sales rules differ by product type.
Shipping availability: United States domestic orders only.
Fulfillment: U.S. domestic fulfillment via Amazon FBA Multi-Channel Fulfillment.
Handling time: Orders are typically processed and shipped within 24 hours.
Estimated delivery: Typically 4–6 days, depending on destination, carrier performance, and peak seasons.
Fulfillment: Shipped from Mainland China with international shipping to supported destinations.
Estimated delivery: Typically 30–60 days, depending on destination country, customs clearance, route capacity, and peak seasons.
Pre-shipment confirmation requirement:
Within 24 hours after receiving your order, we will email you to confirm that you accept the estimated delivery timeframe and the cross-border fulfillment terms applicable to RACK.
If you do not reply within 48 hours, we will follow up; in many cases we will attempt a phone call during a verification window that is typically U.S. evening hours.
We will ship RACK only after you explicitly confirm acceptance.
For eligible products purchased on ADVINCI.shop, ADVINCI provides a one (1) year limited warranty beginning on the date of delivery (as shown by the carrier’s delivery confirmation). This warranty covers manufacturing defects and assembly-related defects that occur under normal and intended use.
If we determine that a covered defect exists, we will provide one or more of the following remedies, at our discretion, consistent with this Policy:
Replacement parts and/or missing parts shipment;
Remote troubleshooting and installation guidance (video/photo instructions);
If necessary, a reasonable resolution such as partial refund, store credit, or an upgrade of parts, as determined by ADVINCI based on the circumstances.
Our principle: We prioritize the fastest and most effective solution to restore product usability while minimizing unnecessary cross-border returns, time loss, and logistics costs.
Because RACK products are large, cross-border shipments with multi-leg logistics and factors outside our control, we take reasonable steps to provide secure packaging and to support you after delivery. To maintain a sustainable service model, the following rules apply specifically to RACK:
After a RACK has shipped, if a quality issue arises, ADVINCI will prioritize replacement parts/missing parts and remote technical support to resolve the issue.
Refunds are generally not provided for RACK after shipment, unless ADVINCI determines that the issue cannot be reasonably resolved through replacement/repair solutions and ADVINCI agrees to an alternative compensation arrangement.
While we strive to provide strong packaging, cross-border transportation may involve impacts, compression, carrier handling, and customs processes that are not fully controllable.
If shipping damage or missing items occur, ADVINCI will prioritize reshipment of the relevant parts/components needed to complete installation and enable use.
Refunds are generally not provided for cross-border shipping damage or missing items for RACK, unless ADVINCI determines that replacement solutions cannot reasonably resolve the issue and ADVINCI elects to provide an alternative remedy.
Because international return freight, duties, warehousing, and handling may exceed the residual product value, RACK products are generally not eligible for “return for refund” after delivery.
In rare, exceptional cases where ADVINCI provides written approval for a return:
International return shipping, duties, warehousing, and handling costs are typically the customer’s responsibility and may be deducted from any refund; and
Such deductions may result in a net refund of $0.
Whenever feasible, we prefer solutions such as replacement parts, technical support, and (if appropriate) partial compensation, to resolve issues faster and reduce cost for both parties.
Except for the RACK special terms in Section 4, the return/refund principles below apply to eligible orders.
You may request a return or refund within 30 days of delivery (based on carrier delivery confirmation).
Requests made after 30 days are generally not accepted for no-reason returns, except where required by applicable law.
To qualify:
The product must be in the condition received: unused or not materially affecting resale, with all parts/accessories included, and with original packaging when applicable.
Return shipping costs are typically the customer’s responsibility.
For international returns, costs may be high; please confirm carefully before ordering.
If you receive an item with damage, missing parts, or an obvious quality abnormality, please submit a claim within 24 hours of delivery and provide supporting evidence (photos/videos).
We will prioritize: replacement parts / technical support / exchange (as applicable).
For Enclosure orders that truly require a return and refund, we will handle the matter based on the actual circumstances and assume responsibility within a reasonable scope.
Cancellations after shipment or refused delivery may result in interception, return freight, and handling costs. Such costs may be deducted from any refund.
For international RACK orders, refusal/return costs can be significant and may materially reduce the refund amount, potentially to $0.
This limited warranty does not cover, and ADVINCI is not responsible for, any issue caused by:
misuse, abuse, accidents, dropping, impact, neglect, or improper handling;
unauthorized modification, disassembly, repair, or service by non-authorized personnel;
incorrect installation, operation outside intended conditions, or improper maintenance (including unreasonable load or incorrect heating/lighting setups that damage materials);
normal wear and tear, cosmetic imperfections that do not affect functionality, or minor scratches;
missing valid proof of purchase or inability to verify order information;
purchases made outside ADVINCI.shop (handled by the original retailer/platform).
To help us resolve issues quickly, please prepare:
Your ADVINCI.shop order number or proof of purchase;
A description of the issue (when it occurred, usage scenario, installation steps);
Clear photos/videos showing: outer carton, shipping label, damage details, missing parts location, and overall product condition;
If shipping damage is involved, please keep the carton and protective materials until the case is resolved.
Recommended timing:
Shipping damage/missing parts: submit within 72 hours of delivery for fastest processing.
Warranty issues: submit as soon as discovered so we can arrange parts and support promptly.
After a returned product is received and inspected (when a return is approved), refunds are typically processed within 3–7 business days.
Posting times vary by payment method and issuing bank and may require additional time.
We may update this Policy from time to time. Updates become effective upon posting.
