Effective Date: October 21, 2026

Welcome to the official returns and refund policy page of www.electronicasteren.com, operated by ELECTRONICA STEREN SA DE CV. As a local Mexican tech accessory store focused on delivering daily tech that fits your busy lifestyle, we curate every local-quality tested phone protection and stable Type-C gear to keep up with the daily routines of our users across the country. To ensure transparent, fair service standards that benefit both our customers and our local operations, we have formulated this policy to clearly outline all rules governing returns, replacements and related transaction arrangements. The core principle of our policy explicitly prohibits standalone only-refund requests without product return, to guarantee that every user can enjoy consistent, high-quality tech accessory products at our reasonable price point. This policy applies to all orders placed on our e-commerce platform after the effective date, and your submission of any order on our site will be deemed as your full acknowledgement and acceptance of all terms specified below.

1. Core Rule: No Standalone Only-Refund Requests Are Permitted

We strictly enforce a ‌no only-refund without physical product return‌ policy across all product categories, including our scratch-resistant phone cases, tangle-free Type-C cables, fast-charging adapters and all other tech accessories sold on our platform. Under no circumstances will we process a full or partial monetary refund for any completed order if you do not return the original purchased product to our designated warehouse in intact, resalable condition that meets our inspection standards.

This rule is set in response to the actual usage scenarios of our local Mexican customers: our products are curated specifically for the busy commutes, warm weather and on-the-go lifestyle of users in Mexico, and we maintain our low-price positioning by minimizing unnecessary operating losses. Only when the original product is returned to us can we verify the actual problem of the product, carry out subsequent quality rectification, restock qualified returned units for normal resale, and avoid passing on the loss caused by unreturned product refunds to all our other local customers through subsequent price increases. Any application that attempts to obtain a refund while retaining the purchased product is a violation of this policy, and our customer service team will reject such requests without exception.

2. Eligibility Conditions for Return Eligible Orders

You can submit a valid product return application within 30 calendar days from the date you successfully sign for your ordered product, if the product meets any of the following conditions:

• The product you received has confirmed manufacturing quality defects that affect normal use, such as a Type-C cable that cannot support fast charging as described on the product page, or a phone case that has obvious cracking defects right after unboxing;
• The product you received does not match the specifications, model or color you selected at the time of checkout, which is caused by our incorrect order picking and delivery;
• The product you received is severely damaged during the local delivery process, rendering it completely unusable for normal daily use.

To be qualified for a successful return processing, the returned product must be kept with its original packaging, all included accessories intact, without obvious man-made damage from misuse, violent impact, or unauthorized disassembly. Products that have been customized with exclusive engravings or exclusive printing according to your personal requirements are not eligible for return, unless the customized product has confirmed manufacturing quality defects.

3. Process of Return and Subsequent Arrangements

When you need to initiate a return application, you can first contact our customer service team via email at zeroco@electronicasteren.com or our official contact phone +52 55 5234 3764 to provide your order number, clear photos or short videos showing the product problem, and explain the specific situation of your return request. Our team will verify the legitimacy of your application within 3 working days, and send you a formal return authorization notice along with the designated return shipping address: Biólogo Maximino Martínez No. 3408, Col. San Salvador Xochimanca, Azcapotzalco, Ciudad de México, C.P. 02870, Mexico.

After you send the product back to us and fill in the return tracking number on our platform, our professional quality inspection team will check the returned product within 5 working days after we receive the parcel. Once your return is confirmed to meet all our eligibility requirements, you can choose one of the two alternative arrangements instead of a direct standalone refund:

• ‌Equal value product exchange‌: You can exchange the returned product for an identical brand new unit of the same product, or exchange it for another tech accessory of the same value in our store. We will cover the full shipping fee to send the new product to your designated address across Mexico;
• ‌Store credit issuance‌: We will issue a store credit with the exact equal value of your original order amount to your account on www.electronicasteren.com, which has no expiration date and can be fully used for any subsequent purchases in our store without any additional restriction.

The shipping cost for returning the product to our side will be covered by us for all return requests caused by our quality fault or wrong delivery. For return requests initiated for non-quality related personal reasons, you only need to bear the basic local return shipping fee.

4. Exclusions and Special Reminders

We do not accept return applications submitted more than 30 calendar days after you sign for the product, nor do we accept return requests for products that show obvious traces of man-made damage, long-term use, or unauthorized modification. We never process any only-refund application that does not include the physical return of the purchased product, and any dispute caused by a user applying for a refund without returning the product will not be supported by our official system.
