Slurry acid

When purchasing Slurry Acid (often referring to Linear Alkyl Benzene Sulfonic Acid or specialized industrial descalers), the most critical factor is the Active Matter content, typically required at 96% or higher for industrial efficiency. You must also verify the Free Oil content (max 2.0%) and Sulfuric Acid content (max 1.5%) to ensure chemical stability. For liquid variants, check the color Klett value (ideally below 50) to ensure it won't discolor your end products, such as detergents or industrial cleaners.

As a chemical substance, Slurry Acid must be accompanied by a comprehensive Material Safety Data Sheet (MSDS) compliant with the GHS (Globally Harmonized System). For international trade, ensure the supplier provides a COA (Certificate of Analysis) for every batch. Depending on the destination, compliance with REACH (EU) or TSCA (USA) is essential. Furthermore, since it is often classified as a corrosive substance, the packaging must meet UN-certified standards for hazardous material transport.

Request a pre-shipment sample and conduct a viscosity and pH level test to ensure it meets your formulation requirements. It is highly recommended to use third-party inspection services (like SGS or Intertek) to verify the chemical composition before the balance payment is made. Additionally, evaluate the supplier's production capacity and storage conditions, as Slurry Acid is sensitive to temperature fluctuations which can lead to product separation or degradation.

Slurry Acid is primarily used as a surfactant in the production of household detergents, dishwashing liquids, and industrial cleaners. In the textile industry, it serves as a mercerizing and washing agent. Functional requirements include high foaming ability, excellent emulsification, and rapid biodegradability. If your application is for specialized industrial descaling, ensure the acid concentration is optimized for calcium and magnesium deposit removal without damaging the substrate metal.

The main risk is leakage and corrosion during transit. Slurry Acid is a corrosive chemical; therefore, you must insist on high-density polyethylene (HDPE) drums or ISO tanks. Ensure the supplier follows IMDG (International Maritime Dangerous Goods) codes strictly. Failure to declare the goods correctly as 'Dangerous Goods' can lead to heavy fines, shipment seizure, or port rejection.

Chemical prices are highly sensitive to raw material costs (like Benzene and Sulfur). It is wise to negotiate a formula-based pricing model for long-term contracts. For MOQs, while standard is often a 20ft container (approx. 18-21 tons), you can negotiate smaller trial orders if you use a consolidated chemical warehouse. Always ask for tiered pricing—bulk discounts typically start at 50 tons or more.

To ensure transaction security, use Secured Trading Services provided by reputable platforms like Made-in-China.com. Avoid 100% upfront payments; a standard 30% deposit and 70% against the Bill of Lading (B/L) is common. For new suppliers, consider using a Letter of Credit (L/C) to mitigate financial risk, ensuring payment is only released upon the presentation of valid shipping and quality documents.

Verify the HS Code (typically 3402.11 or 3402.31) to determine the exact import duties and taxes in your country. Be aware of anti-dumping duties that some regions impose on chemical imports from specific countries. Ensure all labels are in the language of the destination country and include required hazard symbols and emergency contact information to prevent delays during customs inspections.
