Carbolic acid

When purchasing Carbolic Acid (Phenol), the purity level is the most critical factor, typically requiring ≥99.9% for pharmaceutical or high-end chemical synthesis. You must verify the freezing point (should be around 40.6°C to 40.9°C) and the water content (usually ≤0.05%). Additionally, check for color (Hazen) levels to ensure the product has not oxidized, as high-quality phenol should be colorless to white crystalline at room temperature.

As a hazardous chemical, Carbolic Acid must comply with the GHS (Globally Harmonized System) for labeling and packaging. Suppliers should provide a valid MSDS (Material Safety Data Sheet) and COA (Certificate of Analysis) for every batch. For specific industries, look for REACH registration (EU market) or USP/BP grade certifications if the product is intended for medical or antiseptic applications.

Carbolic Acid is a versatile precursor used in the production of phenolic resins, bisphenol A (BPA), and caprolactam. In the medical field, it serves as a powerful antiseptic and disinfectant. Buyers must ensure the chemical's reactivity profile matches their specific synthesis needs, particularly regarding acidity levels and solubility in water or organic solvents.

Due to its corrosive and toxic nature, you must ensure the supplier uses stainless steel or specially coated drums to prevent contamination and corrosion. The product must be stored in a cool, ventilated area away from oxidizers. Verify that the supplier has experience in temperature-controlled logistics if the product needs to remain in a liquid state during transit.

Carbolic Acid is classified as a Class 6.1 Toxic Substance. The primary risk involves customs seizure or shipping delays if the UN Number (UN1671 for solid, UN2312 for molten) and IMDG (International Maritime Dangerous Goods) codes are not correctly declared. Always work with freight forwarders who specialize in DG (Dangerous Goods) cargo to avoid heavy fines.

To mitigate financial risk, use secure payment methods and prioritize suppliers on Made-in-China.com who have undergone Audited Supplier verifications. Request a pre-shipment inspection by a third party like SGS or Intertek to verify the chemical composition and weight before the final balance is paid.

Chemical prices are highly sensitive to raw material (benzene) market fluctuations. Negotiate for formula-based pricing or volume-based discounts (e.g., 5-10% off for full container loads). Additionally, discuss lead time guarantees, as supply chain disruptions in the chemical industry can halt your entire production line.

Ensure the supplier provides a TSCA (Toxic Substances Control Act) declaration for the US or REACH compliance for Europe. Failure to provide these documents will result in the goods being denied entry at the port. Always confirm the Harmonized System (HS) Code (typically 290711) to calculate accurate import duties and taxes.
