Linear alkyl benzene sulphonic

Buyers must prioritize the Active Matter content, which should ideally be 96% or higher. Other critical parameters include Free Oil (Unsulfonated matter) which should be below 2.0%, and Free Sulfuric Acid which should be below 1.5%. Additionally, check the color (Hazen/APHA); a lighter color (typically below 50-80) is essential for producing high-quality, clear liquid detergents or white washing powders.

As a chemical product, LABSA must be accompanied by a comprehensive Material Safety Data Sheet (MSDS). For international trade, ensure the supplier complies with REACH regulations (especially for the EU market) and holds ISO 9001:2015 for quality management. Since it is a surfactant, verify its biodegradability to meet global environmental standards, ensuring the product is environmentally friendly and compliant with local surfactant regulations.

High-purity LABSA (96%) offers the best cost-to-performance ratio because it reduces the volume of raw material needed per batch, thereby lowering logistics and storage costs. Buyers should calculate the cost per unit of active matter rather than just the price per metric ton. Using a lower grade may result in instability in the final formulation, leading to higher costs in the long run due to the need for additional stabilizers or neutralizers.

LABSA is highly acidic and corrosive. It must be stored in corrosion-resistant containers, such as PVC, fiberglass (FRP), or stainless steel tanks. Avoid contact with mild steel to prevent contamination and container degradation. Ensure the storage area is cool, dry, and well-ventilated, away from strong oxidizing agents. For B2B buyers, verifying that the supplier uses UN-approved plastic drums or IBC tanks is crucial for safe transit.

The main risk is leakage and corrosion during sea freight. LABSA is classified under UN Class 8 (Corrosive Substances). Buyers must ensure the supplier provides proper dangerous goods (DG) packaging and accurate IMO declarations. Failure to declare the cargo correctly can lead to heavy fines, shipment seizures, or refusal by shipping lines.

Utilize secure payment methods and consider third-party pre-shipment inspections (such as SGS or Intertek) to verify the active matter percentage and acidity before the balance payment is released. On platforms like Made-in-China.com, prioritize Audited Suppliers who have undergone comprehensive on-site verification of their manufacturing capabilities and business legitimacy.

Chemical prices are often tied to crude oil and benzene market fluctuations. Negotiate for formula-based pricing or volume-based discounts (e.g., 5-10% discount for full container loads/FCL). Additionally, request a fixed price validity period of at least 15-30 days to protect against sudden market volatility during the procurement process.

Check the HS Code (typically 3402.11) for your specific country to determine import tariffs. Be aware of anti-dumping duties that some regions (like India or the EU) may impose on chemicals from specific origins. Always request a Certificate of Origin (CO) from the supplier to take advantage of Free Trade Agreements (FTAs) which can significantly reduce your landed cost.
