For businesses operating in sectors like automotive, textiles, and chemical manufacturing, sourcing high-quality Ethylene Glycol (EG) is paramount. As a critical raw material for antifreeze, polyester (PET) resins, and various industrial solvents, the choice of an Ethylene Glycol supplier directly impacts product performance and operational efficiency. This guide will help procurement managers and R&D scientists identify reliable manufacturers and suppliers of EG, particularly focusing on securing competitive pricing and consistent quality from China.

When evaluating an Ethylene Glycol manufacturer, several factors should be prioritized. Firstly, product purity is non-negotiable. Industrial-grade EG typically requires a purity of ≥99.0%, but specific applications, such as high-grade polyester fiber production, may demand even higher purity levels (e.g., Fiber Grade: ≥99.8%). Verifying adherence to international standards and requesting Certificates of Analysis (CoA) is crucial. Reputable suppliers will readily provide detailed specifications, including density, boiling point, and water content, as outlined in the ASTM standards.

Secondly, a stable production capacity and a robust supply chain are essential. Businesses looking to purchase Ethylene Glycol in bulk need assurance of timely delivery and consistent availability. Factors like the supplier's manufacturing facilities, inventory management, and logistics network play a significant role. For instance, suppliers with factory-backed operations often offer more competitive pricing and greater control over quality assurance. When inquiring about price, it's advisable to ask about bulk order discounts and lead times, which can range from 7-15 days from Chinese ports like Tianjin.

Furthermore, the supplier's experience and customer support are vital. Engaging with a supplier that understands your specific application needs – whether it's for antifreeze formulation, synthetic polyester production, or as an industrial solvent – can lead to better product recommendations and troubleshooting. Many suppliers offer sample orders, allowing you to test the EG's performance before committing to a large purchase. This is a standard practice for many chemical procurement processes.

When considering a purchase, understand the Incoterms (e.g., FOB, CIF) and payment terms (e.g., L/C, T/T) that the supplier offers.
