For procurement managers and product developers in the plastics industry, securing a reliable and cost-effective supply of essential raw materials is a constant priority. Diisononyl Phthalate (DINP), a ubiquitous plasticizer for PVC, is one such critical component. This guide aims to demystify the process of sourcing DINP from China, highlighting the benefits and considerations for international buyers.

China has emerged as a global powerhouse in chemical manufacturing, and DINP is no exception. Numerous Chinese manufacturers specialize in producing high-quality DINP (CAS 28553-12-0) that meets international standards. The primary advantage of sourcing from China lies in the competitive pricing often offered by these large-scale producers. Decades of experience in export, coupled with efficient manufacturing processes, allow them to supply DINP at price points that are difficult to match elsewhere.

When approaching a Chinese DINP manufacturer or supplier, it's essential to conduct due diligence. Look for suppliers with a proven track record of export experience, certifications such as REACH, and positive buyer feedback. Requesting detailed technical specifications, including purity levels (typically ≥99.5%), free phthalate content, acid value, and color (Pt-Co scale), is crucial. Understanding the product's physical properties, such as its appearance as a colorless oily liquid, its density, and flash point, will also aid in your evaluation.

The availability of DINP in various packaging formats is another convenience offered by Chinese suppliers. Common options include 200 kg iron drums, 1000 kg IBC tanks, and large-volume flexitanks (23 Mts), catering to different order sizes and logistical needs. This flexibility simplifies the receiving and storage process at your facility.

To secure the best terms, it is advisable to contact multiple suppliers to compare quotes and lead times. Clearly communicate your specific requirements, including desired purity, quantity, packaging, and delivery timeline. Many Chinese manufacturers are eager to provide samples for testing, which is a vital step in the qualification process. By leveraging the manufacturing capabilities and competitive market in China, businesses can establish a robust and economical supply chain for their DINP requirements.
