1.Q: How can you guarantee the quality?
A: a. At first, our QC staff will inspect the raw material,
b. During the process of before-filling, after-filling and before-delivery we will inspect the sealant too.
c. At last we will keep the sample for around 12 months in case there is any problem so that we can trace it and solve the problem.
2.Q: How to solve the quality problem after sales?
A: Take photos or videos of the problem to us. After confirming the problem, we will make a satisfied solution for you
3.Q: why should you buy from us and not from other suppliers?
A: In the past 10 years, TENGYU has developed into a modern environmental protection adhesive accessories comprehensive platform enterprise integrating R&D, production, sales, and import & export services. Here, you can enjoy our most considerate service and guarantee. We have professional customer service to do after-sales service to ensure that the goods can be delivered on time.
