Levulinic acid

Levulinic Acid (CAS No. 123-76-2) is typically available in two primary grades: Industrial Grade (98% purity) and Pharmaceutical/Food Grade (99%+ purity). For B2B buyers, it is critical to verify the melting point (33-35°C) and refractive index (1.438-1.442). Ensure the product is a white crystalline solid or pale yellow liquid (depending on temperature) with low moisture content, typically ≤0.5%, to prevent degradation during storage.

As a versatile platform chemical, it is widely used in the production of resins, plasticizers, and pharmaceuticals. In the agricultural sector, it serves as a precursor for Delta-aminolevulinic acid (DALA), a biodegradable herbicide. For the fragrance and flavor industry, it is used to synthesize esters like Ethyl Levulinate. Buyers should specify their application to ensure the supplier provides the correct impurity profile, especially regarding heavy metal limits for sensitive applications.

Suppliers must provide a comprehensive Material Safety Data Sheet (MSDS/SDS) compliant with GHS standards. For entry into the EU, REACH registration is mandatory. If the product is intended for food or pharma derivatives, look for ISO 9001:2015 and HACCP or GMP certifications. Ensure the supplier complies with IMO (International Maritime Organization) regulations for the transport of corrosive or irritant substances if applicable.

Modern sourcing prioritizes bio-based Levulinic Acid derived from biomass (cellulose) rather than petrochemical routes. Ask suppliers about their raw material source (e.g., corn stover, wood waste) and their yield efficiency. High-quality manufacturers on Made-in-China.com often utilize advanced acid-catalyzed hydrolysis processes that minimize waste and carbon footprint, which is a significant selling point for eco-conscious brands.

Levulinic Acid is mildly corrosive. It should be packed in UN-approved plastic drums (200L/250kg) or IBC tanks to prevent leakage. For long-distance shipping, ensure the containers are UV-protected and stored in a cool, ventilated warehouse (below 30°C). Always request seaworthy packaging with pallets and shrink-wrap to avoid damage during transshipment.

Utilize Secure Payment services provided by platforms like Made-in-China.com to protect your funds until delivery. Before bulk shipment, mandate a Pre-Shipment Inspection (PSI) by a third party like SGS or Intertek to verify the purity and assay against the provided COA (Certificate of Analysis). Never rely solely on the supplier's internal lab reports for the first three orders.

Focus on Volume-Based Pricing; prices for Levulinic Acid are highly sensitive to raw material (biomass/sugar) costs. Negotiate for a fixed-price contract for 6-12 months if you have stable demand to hedge against market volatility. Additionally, request free samples (100g-500g) for lab testing, but offer to cover the express courier costs to demonstrate serious intent.

Check the HS Code (typically 291830) for specific import duties in your country. Be aware of Anti-Dumping Duties (ADD) that may apply to certain organic acids in specific regions. Ensure all documentation, including the Commercial Invoice, Packing List, and Certificate of Origin, accurately reflects the chemical name and purity to avoid customs delays or seizures.
