Gamma butyrolactone gbl manufacturers

Gamma Butyrolactone (GBL) is a high-performance industrial solvent and chemical intermediate. It is widely used as a cleaner for circuit boards (PCBs) in the electronics industry, a paint stripper, and a solvent in lithium-ion batteries. In the pharmaceutical and agricultural sectors, it serves as a precursor for synthesizing pyrrolidones, herbicides, and vitamin B1. Buyers must ensure the intended use is strictly industrial or laboratory-based.

For high-end industrial applications, buyers should demand a purity level of ≥99.9%. Key technical parameters include moisture content (typically <0.05%) and color index (APHA <10). Ensure the supplier provides a Certificate of Analysis (COA) for every batch and utilizes Gas Chromatography (GC) testing to verify the chemical composition and absence of prohibited impurities.

GBL is a highly regulated substance globally due to its potential for misuse. It is often classified as a List II regulated chemical or a controlled precursor. Buyers must possess the necessary Import Licenses and End-User Certificates (EUC). Suppliers must comply with REACH (EU), TSCA (USA), and international GHS (Globally Harmonized System) labeling standards. Always verify the CAS No. 96-48-0 documentation before proceeding.

GBL is hygroscopic and should be stored in sealed, moisture-proof containers, typically galvanized iron drums (200kg) or IBC tanks (1000kg). It must be kept in a cool, well-ventilated warehouse away from oxidizing agents and open flames. Ensure the packaging meets UN-certified standards for hazardous liquid transport to prevent leakage during cross-border transit.

The primary risks include customs seizure due to improper documentation and supplier non-compliance with international drug precursor laws. To mitigate this, only source from verified manufacturers on Made-in-China.com who have a proven track record of legal exports. Avoid 'too-good-to-be-true' prices, which often indicate substandard purity or fraudulent shipping practices.

Utilize Trade Assurance services to protect your payment until the goods are delivered and inspected. Conduct third-party factory audits (such as SGS or Intertek) to verify the supplier's production capacity and legal permits. Ensure the supplier is a legally registered chemical manufacturer rather than an unlicensed trading entity.

GBL is classified as Dangerous Goods (DG) for transport. You must use a specialized DG freight forwarder experienced in handling Class 9 or relevant hazardous categories. Ensure the Material Safety Data Sheet (MSDS) is provided in the language of the destination country. For shipping, FOB (Free On Board) is often preferred by experienced buyers to maintain control over the specialized logistics chain.

Chemical prices fluctuate based on raw material costs (e.g., Maleic Anhydride) and energy prices. Negotiate based on annual volume contracts rather than spot buys to secure stable pricing. Ask for tiered pricing (e.g., 5-ton vs. 20-ton orders) and clarify if the quoted price includes specialized hazardous material packaging fees.
