Our company specializes in petrochemicals (methanol, styrene, ethylene glycol), plastic resins (PP, PE, PVC, ABS), fine chemicals (pharmaceutical/pesticide intermediates, additives, solvents), chemical fiber raw materials (PTA, polyester filament, polyester staple fiber), inorganic chemicals (soda ash, caustic soda, titanium dioxide), as well as rubber, paraffin wax, and other products. We offer one-stop procurement services covering a wide range of categories.


2. Are you a trading company or a manufacturer?
We are a professional chemical trading company specializing in international trade. We have established long-term strategic partnerships with numerous high-quality domestic manufacturers to ensure a stable supply of goods and competitive pricing, while also providing comprehensive export services throughout the entire process.


3. Can you provide third-party inspection reports?
Yes. We provide a Certificate of Analysis (COA) with every shipment. Additionally, upon a client's request, we can arrange for inspections by third-party agencies such as SGS, BV, or ITS; the associated costs and details are negotiable.


4. What is the Minimum Order Quantity (MOQ)?
For plastic resins and chemical fiber raw materials, the MOQ typically starts at 1–5 tons, and we welcome small-batch trial orders. For liquid chemicals, bulk shipments start at 20 tons, while drummed shipments can be consolidated (LCL). For fine chemicals, the MOQ is determined on a case-by-case basis depending on the specific product.


5. From which ports do you primarily ship?
Our company is located in close proximity to the Port of Tianjin. We can also arrange shipments from other major domestic ports—such as Qingdao or Shanghai—to meet our clients' specific requirements.
