We are a company based in Guangzhou and Huizhou, Guangdong Province, China. Our sales department is in Guangzhou, and our production department is in Huizhou. Guangdong Province is China's leading automotive province, home to not only Toyota and Honda's production bases in China but also local automotive brands like BYD, Xpeng, and Huawei. We have grown within this industrial belt, focusing on the production and sale of automotive NOx sensors.

Are we safe and trustworthy? Can you receive your goods after payment? Please trust us. NOx sensors are a niche product. Beyond a small number of DIY car repair enthusiasts, most people who know about them are professionals in the automotive manufacturing and repair industries.
We've set up this sales website primarily to serve business buyers, especially auto parts distributors, auto repair shops, and companies with their own vehicle fleets. If you are an individual buyer, please email us your relevant information first to confirm if we can ship to you.
For business buyers, our sales process is as follows:
-
You email us to confirm the product model of the NOx sensor you need and any customization requirements.
-
After confirming that the product can be produced and supplied, we will send you a Proforma Invoice and our bank account details.
-
After receiving payment, we will begin production. We expect to ship within 5 business days, with DHL as our default logistics partner.
-
After the goods are shipped, we will provide you with a Commercial Invoice for customs clearance and a tracking number for you to monitor the shipping progress.
-
Upon receiving the goods, please inspect them and confirm the order completion via email.

For first-time business buyers, we highly recommend starting with a small order (even just one unit) to test the entire process. International procurement can present challenges with payment, logistics, and customs clearance/taxation. To help you navigate this, we offer free shipping on your initial small-batch order. This not only helps us streamline the purchasing process but also allows you to evaluate if our products meet your requirements.
If you're unfamiliar with customs clearance and taxation procedures, or unsure if logistics can deliver to your location, please contact us. We'll coordinate with our logistics providers to see if they can assist with customs clearance.
We believe that starting with small orders helps establish a smooth procurement process and builds mutual trust. We are confident in the quality of our products, which is why we offer free replacements for any defective items in every batch.
