Peg 8000

When purchasing PEG 8000, the most critical factor is the Molecular Weight range, which should be strictly between 7000 and 9000 g/mol. You must verify the Hydroxyl Value (12–16 mg KOH/g) and the Melting Point (60°C–63°C). For industrial or pharmaceutical applications, ensure the pH value of a 5% aqueous solution is between 4.5 and 7.5 to maintain chemical stability.

Quality requirements vary by application. For pharmaceutical or cosmetic grades, the product must comply with USP/EP (United States Pharmacopeia / European Pharmacopoeia) standards and be free from Ethylene Oxide and 1,4-Dioxane residuals. For industrial grades used in lubricants or binders, focus on moisture content (typically <0.5%) and color (APHA/Hazen scale <50) to ensure it doesn't discolor your final product.

PEG 8000 is a versatile high-molecular-weight polymer used as a binder in tablet manufacturing, a viscosity modifier in cosmetics, and a lubricant in rubber processing. Its primary functions include water solubility, low toxicity, and excellent thermal stability. In the textile industry, it serves as an antistatic agent and softener, while in wood processing, it acts as a dimensional stabilizer.

A professional supplier should provide an ISO 9001 certification for quality management. If you are importing for food or drug contact, look for GMP (Good Manufacturing Practice) or REACH registration for the European market. Always request a COA (Certificate of Analysis) and an MSDS (Material Safety Data Sheet) for every batch to ensure safety and regulatory compliance.

PEG 8000 is hygroscopic (absorbs moisture) and sensitive to high temperatures. Ensure the supplier uses moisture-proof packaging, such as 25kg plastic-lined woven bags or fiber drums. Specify that the cargo should be stored in a cool, dry, and well-ventilated warehouse and kept away from strong oxidizers during transit.

Focus on volume-based pricing tiers; since PEG 8000 is a commodity chemical, margins are slim, and discounts usually trigger at 5-ton or 10-ton thresholds. Request a pre-shipment sample from the actual production lot and use Trade Assurance services on Made-in-China.com to protect your payment until the quality is verified by a third-party inspector like SGS or Intertek.

Check the HS Code (typically 3907.29) for specific import duties in your country. Be aware of anti-dumping duties that may apply to chemical products from certain regions. For shipping, ensure the supplier provides a Non-Hazardous Chemical Declaration if the product is classified as non-DG (Dangerous Goods) to simplify customs clearance and reduce freight costs.

Conduct a factory audit or hire a local agent to verify the supplier's production capacity and environmental permits. On Made-in-China.com, prioritize Audited Suppliers who have undergone on-site verification. Check their export history to see if they have experience shipping to your specific region, which ensures they understand your local customs documentation requirements.
