We help you source Ultroviolet Absorber UV-327 in China

Our Advantages:

China currently plays a very important role in the world market for plastic additives, with 168, 1010, DSTDP, DLTDP, 977 and 365 being the most produced products in the world.
The price of plastic additives varies significantly with oil, while the cost correlation between antioxidants and palm oil is high. Since 2020, the number of black swan events in the world has increased, resulting in dramatic changes in raw material prices.
Companies such as UPP, SONGWON, PMC, LG, etc. have been alerted by us in time and have avoided many losses.

We have a 20+ year track record of working with suppliers in China and rating reports on them, and we keep our suppliers updated with the latest news so our customers can get the latest supplier reports. We know the market well and have early warning notifications on upstream raw material prices to help you build a stable supply chain.

When selecting suppliers, our procurement specialists will audit the qualification of suppliers, conduct thorough investigations such as field visits and sample testing, and make ratings to ensure the authenticity and legality of supplier information.

We have a long-term stable cooperation with GLP laboratories, encounter customer test results and supplier test results do not match the situation, we will commission a third party to test to ensure the accuracy, authenticity and reliability of the experimental results. In this way, we can effectively control the product quality problems.

We have a long-term cooperative warehouse and can follow up packaging and labeling according to safety regulations and customer requirements. In order to effectively prevent damage to the goods in transit, we have prepared various reinforcement measures and packaging solutions.
