pbo lead oxide

When purchasing Lead Oxide (PbO), the purity level (typically 99.0% to 99.9%) is the most critical factor. For the battery industry, look for low metallic lead content (less than 0.05%) and specific particle size distribution (D50) to ensure chemical reactivity. For glass and ceramics, the iron (Fe) content must be extremely low (below 10-20 ppm) to prevent discoloration of the final product.

Ensure the supplier provides a Certificate of Analysis (COA) for every batch. Since Lead Oxide is a hazardous material, it must comply with REACH (for EU markets) and be accompanied by a comprehensive Material Safety Data Sheet (MSDS). Verify that the manufacturer follows ISO 9001 for quality management and ISO 14001 for environmental management, as lead production is strictly regulated globally.

PbO is primarily used in Lead-Acid Battery production, where high oxidation degrees are required. In the glass and crystal industry, it acts as a flux to increase the refractive index. For stabilizers in PVC, the chemical stability and fineness of the powder are paramount. Always specify your end-use application to the supplier so they can recommend either Yellow Litharge (canary yellow) or Red Lead (Minium) based on your chemical requirements.

Due to its high density and toxicity, Lead Oxide is usually packed in 25kg multi-layer paper bags with PE liners or 1,000kg big bags (FIBC). Ensure the packaging is moisture-proof and UV-resistant to prevent clumping or chemical degradation during long-term sea transit. Bags must be palletized and shrink-wrapped to prevent leakage, which is a major safety violation in cross-border shipping.

Lead Oxide is classified under UN Class 6.1 (Toxic Substances). You must ensure the supplier provides a UN-certified packaging certificate. Shipping must be handled by carriers authorized to move Dangerous Goods (DG). Always confirm the IMDG Code requirements for sea freight to avoid port rejection or heavy fines.

Use Trade Assurance services on Made-in-China.com to protect your payment until delivery is confirmed. For high-volume chemical orders, it is highly recommended to hire a third-party inspection agency (like SGS or Intertek) to perform pre-shipment sampling and testing to ensure the chemical composition matches the agreed specifications.

Lead prices are tied to the London Metal Exchange (LME). Negotiate a pricing formula based on the LME Lead spot price plus a fixed processing fee. This transparency protects both parties from market volatility. Additionally, request volume-based discounts if your annual consumption exceeds 100 metric tons.

Check your local environmental protection agency (EPA) regulations regarding the import of lead compounds. Some countries require an import license for toxic substances. Ensure all labels are in the destination country's language and include the correct GHS (Globally Harmonized System) pictograms to avoid customs clearance delays.
