Iodine Prills – High-Purity Crystalline Iodine

Iodine is a dark violet to blackish-blue crystalline element (halogen) with a distinctive sharp, pungent odor. It sublimes when heated and exhibits moderate solubility in water, dissolving readily in alcohol, ether, and potassium iodide solutions. Moon Bright Resources supplies high-purity iodine prills — spherical, uniform particles produced through specialized prilling technology. Unlike conventional flake or lump iodine, prilled iodine offers superior flowability, reduced dusting, and consistent particle size for precise dosing and blending operations.

Iodine is an essential micronutrient for human and animal health, playing a critical role in thyroid hormone production (thyroxine T3 and T4). It is also a powerful antiseptic and disinfectant. Our iodine prills meet USP, BP, and EP purity standards, making them suitable for pharmaceutical manufacturing, nutritional supplements, veterinary products, and industrial applications requiring high purity and consistent performance.

FAQ – Frequently Asked Questions

Q1: What is the advantage of iodine prills over flakes or lump?
A1: Iodine prills offer three key advantages: (1) superior flowability — spherical shape prevents bridging in hoppers and feeders, enabling automated dosing; (2) minimal dust — reduces product loss and worker exposure; (3) uniform particle size — ensures consistent blending and dissolution rates. For pharmaceutical blending, animal feed premix production, and any application requiring accurate, repeatable dosing, prilled iodine is the preferred form. Flakes and lump are suitable for less demanding applications where simple manual handling is acceptable.

Q2: How should iodine prills be stored and handled safely?
A2: Iodine is moderately toxic and corrosive. Store in original tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight, heat, and incompatible materials (ammonia, reducing agents, metals, alkalis). Protect from moisture. Use appropriate PPE including nitrile or neoprene gloves, safety goggles, and dust mask. Avoid inhalation of sublimed vapors. In case of skin contact, wash with soap and water. Iodine sublimes slowly at room temperature — avoid opening containers unnecessarily. Shelf life is 36-48 months when stored properly in sealed containers.

Q3: Do you offer OEM / private label packaging?
A3: Yes, Moon Bright Resources provides full OEM services for iodine prills. We can repackage under your brand name with custom-printed containers (1 kg to 50 kg drums), custom prill size specifications (1-4 mm or tighter range), and pharmaceutical/USP certification with full traceability documentation. Minimum OEM order quantity is 100 kg. We also offer custom labeling with batch numbering, tamper-evident seals, and child-resistant packaging for retail applications. USP/EP grade certificates available with each OEM shipment.

Q4: What is your minimum order quantity (MOQ)?
A4: MOQ is 1 kg for sample orders, 25 kg for small commercial orders (one drum), and 500 kg for wholesale pricing. Bulk orders of 1 metric ton or more qualify for discounted rates. For OEM private label orders, MOQ is 100 kg. Pharmaceutical/USP grade with full documentation requires a minimum of 25 kg. Full container loads (typically 10-15 metric tons) receive maximum discount.

Q5: What purity grades of iodine do you offer?
A5: We offer multiple purity grades: (1) Technical Grade — 99.5% minimum, suitable for chemical synthesis, animal feed, and industrial applications; (2) Pharmaceutical/USP Grade — 99.8% minimum, meets USP, BP, and EP standards, suitable for drug manufacturing and human nutrition; (3) Ultra-High Purity — 99.9% minimum, for electronics and specialty applications. Certificate of Analysis (COA) provided with every shipment specifying purity, heavy metals, non-volatile residue, and other key parameters.
