At our factory, every trash can lid hinge mechanism is backed by a structured warranty designed to give you confidence in long-term durability. Specifically, we offer a limited five-year warranty on the hinge mechanism itself. This covers any manufacturing defects in material or workmanship, including cracking, pin breakage, or failure of the spring-assisted return function under normal household or commercial use. During the warranty period, we will repair the hinge free of charge or replace the entire lid assembly if the hinge is deemed irreparable. The warranty does not cover damage caused by misuse, excessive force, intentional modification, or exposure to extreme temperatures beyond the product’s rated range. To make a claim, simply contact our customer support team with your purchase receipt, the model number, and a short video demonstrating the hinge issue. Once verified, we ship the replacement parts or a new lid within five business days. For original equipment manufacturers or bulk buyers, we also offer an extended warranty package that elevates hinge coverage to ten years, paired with priority technical support. Our after-sales service centers are located in three regions to reduce shipping time and cost. We believe a hinge should last as long as the bin itself, so we rigorously test every hinge model through 100,000 open-close cycles before approving it for production. If you are evaluating our trash cans for a project, we can provide a written warranty certificate that lists all terms in plain language. Ultimately, our warranty is not just a piece of paper — it is our commitment to keeping every lid swinging smoothly for years.
