I. How to Choose a DINP Supplier
When sourcing plasticizers, the stability of a DINP supplier supply chain and their quality control capabilities directly determine the pace of downstream production. As a DINP supplier, Shandong Aojin Chemical offers a long-term supply of industrial-grade DINP (Diisononyl phthalate) and supports full-container shipments to major ports.
Basic DINP Information:
Chinese Name: Diisononyl phthalate
English Name: Diisononyl phthalate (DINP)
CAS No.: 28553-12-0
Molecular Formula: C₂₆H₄₂O₄
Molecular Weight: 418.61
HS Code: 2917330000
Appearance: Colorless, transparent, oily liquid
Main Applications: Primary plasticizer for PVC; used in wire and cable, artificial leather, plastic flooring, flexible PVC products, rubber-plastic accessories, etc.
II. Delivery Capabilities for Full-Container DINP Exports to Japan
For the Japanese market, Aojin Chemical provides end-to-end export services from the factory to the port:
1. Standard Packaging: Packed in 200kg iron drums.
2. Full Container Loading: Supports 20GP/40GP container shipments; drums undergo inspection and reinforcement prior to loading.
3. Complete Documentation: Provides a full set of export documents—including invoices, packing lists, bills of lading, MSDS, and Certificates of Analysis (COA)—to meet Japanese import customs clearance requirements.
Demand for DINP in Japan's plastics manufacturing industry remains consistently stable. Sectors such as wire and cable, automotive interiors, and plastic building materials demand high heat resistance and low volatility from plasticizers; compared to traditional DOP, DINP offers superior performance regarding volatility loss and migration resistance, making it a mainstream choice for downstream customers in Japan.
III. DINP Pricing and Wholesale Price Information
DINP prices are influenced by multiple factors, including market trends for raw materials (such as crude oil, phthalic anhydride, and isononyl alcohol), supply and demand dynamics, fluctuations in ocean freight rates, and delivery terms at the destination port. Therefore, the wholesale price of DINP is not fixed but is closely linked to the following factors:
Purchase Quantity: The unit price for full-container orders is significantly lower than for loose-drum orders; larger volumes allow for greater bargaining power.
Delivery Terms: Prices vary based on terms such as FOB Qingdao or CIF Japanese ports (e.g., Tokyo, Yokohama, Osaka, Kobe).
Packaging Requirements: Standard 200kg steel drums are the default; special packaging requirements require separate cost calculations.
Procurement Cycle: Customers with long-term agreements can lock in prices for specific periods, mitigating the risk of short-term raw material price fluctuations.
Customers looking to purchase DINP for the Japanese market are advised to contact Aojin Chemical directly for real-time quotes and to confirm product specifications, container loading capacity, shipping schedules, and documentation arrangements.
FAQ (Frequently Asked Questions)
Q1: Is Aojin Chemical a DINP supplier?
A: Yes, Aojin Chemical is a DINP supplier and can provide samples and COA (Certificate of Analysis) reports.
Q2: What are the CAS number and molecular formula for DINP?
A: DINP (Diisononyl phthalate) has the CAS number 28553-12-0, molecular formula C₂₆H₄₂O₄, molecular weight 418.61, and HS code 2917330000.
Q3: What is the current price of DINP? How is the wholesale price calculated?

Wholesale prices are calculated based on factors such as purchase quantity (full container vs. loose drums), delivery terms (FOB/CIF), and the destination port. Please contact us directly for the current real-time quote.
Q4: Can DINP be shipped to Japan in full containers? Which ports are supported?
A: Yes. Aojin Chemical can arrange full-container exports of DINP to major Japanese ports, including Tokyo, Yokohama, Osaka, Kobe, and Nagoya.
Q5: What are the packaging specifications and full-container loading capacity for DINP?
A: Standard packaging consists of 200 kg steel drums. A full 20GP container holds approximately 80 drums (approx. 16 metric tons), while a 40GP container holds approximately 160 drums (approx. 32 metric tons); actual loading quantities depend on the specific securing plan and the shipping line's weight limits.
Q6: What products is DINP primarily used for?
A: DINP is a high-performance, general-purpose plasticizer. It is mainly used in applications such as flexible PVC products, wires and cables, artificial leather, plastic flooring, wallpaper, automotive interiors, and rubber-plastic seals. It is characterized by low volatility, heat resistance, and migration resistance.
Q7: Can you provide samples and an MSDS?
A: Yes. We can provide DINP samples (freight collect) as well as MSDS, COA, and test reports in both Chinese and English for quality verification and customs clearance purposes.
