Glycerine price

Glycerine is primarily categorized into USP/BP Grade (Pharmaceutical), Food Grade (FCC), and Technical Grade. For B2B buyers, ensuring a purity level of 99.5% or higher is standard for high-end applications. You must verify the source, as it can be Vegetable-based (Palm, Coconut, or Soy), Animal-based (Tallow), or Synthetic. Vegetable-derived glycerine is currently the most sought-after due to Halal and Kosher requirements.

Key parameters include Color (APHA), where a lower number indicates higher clarity; Specific Gravity (typically ≥1.261 at 25°C); and Water Content (usually <0.5%). For pharmaceutical use, the Heavy Metals content (Pb, As) and Diethylene Glycol (DEG) / Ethylene Glycol (EG) limits are critical. Buyers should demand a Certificate of Analysis (COA) for every batch to ensure these levels meet safety thresholds.

Depending on the industry, you should look for ISO 9001 for quality management, HACCP or ISO 22000 for food safety, and GMP (Good Manufacturing Practice) for pharmaceutical applications. If exporting to the EU, REACH registration is mandatory. For North American markets, FDA registration and USP compliance are the primary benchmarks for quality assurance.

The price of glycerine is highly volatile as it is a by-product of Biodiesel and Oleochemical production. When palm oil prices rise or biodiesel subsidies change, glycerine prices fluctuate. Refined Glycerine offers better stability for formulations, while Crude Glycerine (80% purity) is more economical for industrial applications like anti-freeze or waste-water treatment, provided you have the capacity to process it.

The most significant risk is DEG/EG contamination, which can lead to legal and health crises. Always use third-party inspection services (like SGS or Intertek) to sample the product at the loading port. Another risk is leakage during transit; ensure the supplier uses UN-approved HDPE drums, IBC tanks, or Flexitanks with proper bracing to prevent movement in the container.

Focus on Volume-Based Pricing and Long-term Contracts. Since glycerine is a commodity, spot prices change weekly. Negotiating a formula-based price linked to market indices (like ICIS) can protect you from sudden spikes. Additionally, request Free Time at Destination (Detention/Demurrage) of at least 14 days to allow for customs clearance and lab testing without incurring extra costs.

Glycerine is hygroscopic (absorbs moisture from air), so airtight sealing is vital. For shipping to specific regions, ensure the MSDS (Material Safety Data Sheet) is provided in the local language. When sourcing from Made-in-China.com, prioritize Audited Suppliers who have experience with ISO Tank logistics, as this reduces packaging waste and lowers the per-ton freight cost for large-scale orders.

Utilize Escrow services or Letter of Credit (L/C at sight) for initial orders with new suppliers. Avoid 100% T/T advance payments. Ensure the Proforma Invoice (PI) clearly states the batch number, shelf life (typically 2 years), and storage conditions. Verify the supplier's export history on Made-in-China.com to confirm they have a proven track record of delivering consistent chemical quality.
