Calcium bromide

Calcium Bromide is predominantly used in the oil and gas industry as a completion fluid, drilling fluid, and workover fluid. Its high density and clear brine properties make it ideal for controlling wellbore pressure and preventing formation damage. Additionally, it is utilized in mercury emission control for coal-fired power plants and as a component in photography and medicine.

Buyers must verify the purity levels, typically requiring 96% min for solid powder or a 52% min concentration for liquid brine. Key chemical parameters include pH value (usually 6.5-8.0), specific gravity (1.70 g/cm³ min for liquid), and maximum limits for impurities like Chlorides, Sulfates, and Heavy Metals. For oilfield use, crystallization temperature (TCT) is a critical metric to ensure the fluid remains stable in cold environments.

As a chemical product, it must be accompanied by a comprehensive Material Safety Data Sheet (MSDS). For international trade, ensure the supplier provides COA (Certificate of Analysis) for every batch. Depending on the destination, compliance with REACH (EU) or TSCA (USA) is essential. Since it is often classified as a non-hazardous chemical for transport (unless mixed), verify the HS Code (typically 282759) for correct customs declaration.

Prioritize suppliers with ISO 9001:2015 certification to ensure consistent manufacturing processes. Request third-party inspection reports from agencies like SGS or Intertek before shipment. It is also advisable to evaluate the supplier's annual production capacity to ensure they can handle large-scale procurement without compromising on the chemical stability and moisture content of the product.

The primary risks include moisture absorption (hygroscopicity) during transit, which can cake solid powder, and leakage of liquid drums. To mitigate this, ensure the use of moisture-proof PP/PE bags (25kg) or heavy-duty IBC tanks (1700kg). Another risk is price volatility due to fluctuations in raw bromine costs; buyers should consider long-term supply contracts to lock in pricing.

When sourcing on Made-in-China.com, leverage the Audit Reports provided by the platform to verify the supplier's factory status. Negotiate based on volume-tiered pricing, as orders exceeding 20 metric tons (one full container load) usually qualify for significant discounts. Request free samples (shipping excluded) to conduct laboratory testing before committing to a bulk purchase.

Utilize secure payment methods such as L/C (Letter of Credit) for large orders to protect capital. For shipping, ensure the supplier follows IMO (International Maritime Organization) guidelines for chemical handling. It is recommended to use FOB (Free On Board) terms if you have a reliable freight forwarder, or CIF (Cost, Insurance, and Freight) to have the supplier manage the complexities of maritime insurance and logistics to your specific port.
