Thiourea
Thiourea, also known as thiocarbamide, is an organic sulfur compound with the formula CH4N2S and CAS number 62‑56‑6. The product is supplied as a white crystalline solid with a stated purity range of 99.0 % to 99.5 % for industrial use. It is packaged in bulk, most commonly in 25 kg paper bags or 50 kg steel drums, to suit large‑scale chemical processing operations. The supplier notes that the material is a key raw material for thiourea dioxide, pharmaceutical intermediates and rubber accelerators.
Typical industry specifications for bulk thiourea include a moisture content of 0.5 % or less, particle size below 200 µm and a pH of 5.5‑6.5 for a 1 % aqueous solution; these values are not listed by the supplier but are standard for this grade. Storage is recommended at 15‑25 °C in a dry environment to maintain stability. The compound is also used in metal flotation, photographic processing, resin synthesis and as a bleaching aid in textile dyeing, making it versatile for multiple downstream applications.
Buyers should obtain a formal quotation that outlines packaging options, shipping terms and any required documentation such as a Material Safety Data Sheet. Because the listing does not disclose minimum order quantity, lead‑time or payment conditions, those details must be clarified directly with the supplier before confirming the purchase.

Sourcing Thiourea from Henan Langrui Chemical Co. Ltd. - Hong Kong Import Guide
When sourcing thiourea, first confirm the supplier’s harbour verification status, request a recent Certificate of Analysis and ask for any ISO or other quality certifications that apply to the batch you intend to purchase. Verify the exact purity, moisture content and packaging condition before finalising the order, and consider requesting a sample for independent testing if the volume permits.
Logistics for bulk thiourea typically involve sea freight from a Chinese port to Hong Kong or onward destinations. The listing does not state Incoterms, lead‑time or payment terms, so you should ask the supplier to specify whether FOB, CIF or DDP is preferred, the expected production lead‑time and acceptable payment methods such as T/T, L/C or Pay‑by‑Letter.
Arrange a pre‑shipment inspection that includes visual examination of packaging, verification of the COA and MSDS, and if possible a random laboratory analysis of the batch. Ensure that all documentation, including the commercial invoice, packing list and any required customs certificates, is prepared in advance to avoid clearance delays upon arrival.
