Return & Refund Policy

United States and Southeast Asia
Effective Date: July 1, 2026 | Last Updated: July 1, 2026

This Return & Refund Policy applies to eligible purchases of oil seals and related sealing products made through https://preqseal.com, operated by Monsun (Tianjin) Import and Export Co., Ltd. under the brand Preqseal. It explains our return, refund, exchange, and cancellation procedures for customers in the United States, Vietnam, Thailand, Malaysia, Singapore, and the Philippines.

This Policy does not limit any refund, repair, replacement, cancellation, or other remedy that is mandatory under applicable consumer law. Where applicable law provides more favorable rights, those rights will apply.

1. Standard Return Window

Unless a product page, quotation, promotion, or applicable law states otherwise, you may request a standard return within 15 calendar days after confirmed delivery. Contact preqseal@gmail.com before sending any product back. Returns sent without written authorization may be refused or delayed.

2. Return Eligibility and Condition

To qualify for a discretionary return, the product must be new, unused, uninstalled, clean, complete, and in its original packaging, without wear, scratches, deformation, contamination, lubrication, missing parts, or any other condition that affects resale. You must provide the order number and reasonable proof of purchase. We may request photographs, video, measurements, or other information before authorizing a return.

Customers are responsible for checking the product model, dimensions, sealing material, operating temperature, pressure, speed, medium, installation requirements, and compatibility before purchase and installation. Products that have been installed, tested in machinery, lubricated, altered, or damaged through improper handling are not eligible for a discretionary return, except where a defect or mandatory consumer right applies.

3. Non-Returnable or Restricted Items

Customized, made-to-order, specially manufactured, or modified products are non-returnable unless they are defective, damaged, incorrectly supplied, or otherwise non-conforming. Products expressly identified as final sale before purchase, including qualifying promotional or clearance items, are also non-returnable where permitted by law.

A non-returnable designation does not remove remedies for products that are defective, damaged in transit, incorrectly supplied, materially misdescribed, counterfeit, unsafe, or otherwise non-conforming where applicable law provides a remedy.

4. How to Request a Return

  • Email preqseal@gmail.com with your order number, product name or model, quantity, reason for return, and relevant photographs or video.
  • Wait for written authorization and return instructions. Authorization to send a product back does not guarantee a refund until inspection is complete.
  • Send an approved return only to: Room 318, 3rd Floor, TEDA Tower, 256 Jiefang South Road, Hexi District, Tianjin, China. Do not send returns to another office, warehouse, supplier, or carrier location unless instructed in writing.
  • Pack the product securely and include any return authorization number or documentation provided by us.

5. Damaged, Defective, Missing, or Incorrect Items

Inspect your order promptly. Report visible shipping damage, missing items, incorrect products, or apparent manufacturing defects within 7 calendar days after delivery by contacting preqseal@gmail.com. Provide photographs of the outer package, shipping label, internal packaging, product, markings, dimensions, and the relevant damage or discrepancy.

For a verified seller error, transit damage, manufacturing defect, or non-conforming product, we may provide a repair, replacement, reshipment, partial refund, or full refund as appropriate and as required by law. We will pay or reimburse reasonable return shipping when the return results from our error or an eligible defect, unless another lawful remedy is agreed.

6. Exchanges

We do not offer direct exchanges. If you need a different model, size, material, or specification, you must return the eligible product in accordance with this Policy and place a new order. Any price difference, stock limitation, promotional restriction, shipping charge, duty, or tax treatment will apply to the new order.

7. Return Shipping, Duties, and Risk

For returns caused by the customer, including change of mind, incorrect selection, or an unsuitable size, model, specification, or material, the customer is responsible for return shipping and related costs. For verified returns caused by our error, including wrong shipment, eligible quality defects, or transit damage for which we are responsible, we will pay or reimburse reasonable return shipping.

Use a trackable service and retain proof of shipment. Unless applicable law or our written instructions state otherwise, you are responsible for the return until it reaches the approved return location. For international returns, accurately describe the package as returned merchandise and follow carrier and customs instructions. We are not responsible for duties, taxes, storage, brokerage, or penalties caused by inaccurate return documentation.

8. Inspection and Restocking Fee

We inspect returned products after receipt. If a product does not meet the disclosed return conditions, we may deny the discretionary return, reduce the refund to reflect loss in value, or send the product back at the customer's cost where permitted by law.

For an approved discretionary return caused by the customer, we may deduct a restocking fee equal to 10% of the returned product's actual purchase price, but only where the fee was disclosed before purchase and is permitted by applicable law. No restocking fee applies to defective, damaged, incorrectly supplied, or materially misdescribed products, or where applicable law requires a full remedy.

9. Refund Method and Timing

Approved refunds for returned products are normally initiated within 15 business days after the returned products are received, inspected, and approved. Refunds are issued to the original payment method unless another method is required by law or agreed in writing. Your bank or payment provider may require additional time to post the refund.

Original outbound shipping, expedited service charges, duties, taxes, brokerage, and other non-recoverable charges are refundable only when required by law, caused by our error, or expressly included in the approved remedy. Refunds for cancelled unshipped orders will be processed promptly in accordance with applicable law.

10. Order Cancellation and Changes

You may request cancellation or an address change within 2 hours after placing an order, provided that fulfillment, production, customization, or shipment has not started. Contact preqseal@gmail.com immediately. A request is not effective until confirmed by us in writing, and cancellation or address changes are not guaranteed once order processing has begun.

If we cannot ship within the time promised at purchase, we will provide an updated estimate and, where required by applicable law, offer the option to accept the delay or cancel the unshipped order for a prompt refund.

11. Refused, Unclaimed, and Undeliverable Packages

Refusing delivery or failing to collect a parcel does not automatically create an approved return. If a package is returned because of an incorrect address, refusal, unpaid import charges, failure to provide customs information, or non-collection, we may deduct actual return freight, storage, brokerage, duty, and other non-recoverable costs from any refund where permitted by law and supported by records.

12. Warranty Claims

We do not provide an additional commercial warranty unless a specific warranty is stated on the relevant product page, quotation, invoice, or written agreement. Any stated warranty does not cover normal wear, incorrect product selection, improper installation, misuse, incompatible operating conditions, accidental damage, unauthorized modification, contamination, or failure to follow instructions. Mandatory statutory rights remain unaffected.

13. Chargebacks and Payment Disputes

Please contact preqseal@gmail.com so that we can try to resolve a problem before you initiate a chargeback. Nothing in this section prevents you from using lawful payment-dispute rights. Knowingly submitting false information or seeking duplicate recovery may be treated as fraud.
