Wholesale gbl cleaner manufacturers

GBL (Gamma-Butyrolactone) is primarily used as a high-efficiency industrial solvent and cleaning agent. Key specifications include a purity level of 99.9%, a moisture content of <0.05%, and a clear, colorless liquid appearance. It is widely utilized in the electronics industry for cleaning circuit boards, in the automotive sector for wheel rim cleaning and paint stripping, and as a chemical intermediate in the production of herbicides and pharmaceuticals. Buyers must ensure the CAS No. 96-48-0 matches their technical requirements.

Due to its chemical nature, GBL is strictly regulated. Suppliers must provide a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch. For international trade, compliance with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) is essential for the EU market, while TSCA (Toxic Substances Control Act) compliance is necessary for the US. Furthermore, ensure the supplier adheres to ISO 9001:2015 for quality management and ISO 14001 for environmental standards.

Buyers should request third-party lab testing (such as SGS or Intertek) to verify the purity and acidity levels. It is critical to check the refractive index (1.434-1.436) and boiling point (204°C) to ensure the product has not been diluted. Always request a pre-shipment sample to test its solubility and reaction with specific substrates (like plastics or alloys) relevant to your intended application.

GBL is classified as a controlled substance or precursor chemical in many jurisdictions (e.g., Schedule 1 in some regions, or monitored under the DEA in the US). Buyers must possess the necessary import licenses and permits required by their local government. Failure to provide correct documentation can lead to customs seizure, heavy fines, or legal prosecution. Always consult with a licensed customs broker before finalizing the transaction.

To mitigate fraud, prioritize suppliers on Made-in-China.com who have undergone On-site Audits and possess Verified Supplier status. Use secure payment methods like Escrow or Letters of Credit (L/C) to ensure funds are only released upon proof of shipment. Avoid suppliers who insist on untraceable payment methods like Western Union or cryptocurrency for high-volume chemical orders.

GBL must be transported as Dangerous Goods (DG) according to IMDG (sea) or IATA (air) regulations. It should be packed in UN-approved HDPE drums or IBC tanks to prevent leakage and reaction with the container. Ensure the shipping labels clearly display the UN Number (UN 2810 or similar depending on concentration) and Hazard Class. Buyers should choose freight forwarders who specialize in Class 6.1 or Class 9 chemical logistics to ensure safe delivery to the destination country.
