Hydroxylamine hydrochloride

For B2B procurement, the standard purity for Hydroxylamine Hydrochloride (CAS No. 5470-11-1) is typically ≥99.0%. Key technical indicators include low heavy metal content (≤0.0005%), low iron (Fe) content (≤0.0005%), and a clear, colorless solution when dissolved in water or alcohol. Buyers should request a Certificate of Analysis (COA) for every batch to ensure the acidity (pH of 5% solution) falls within the range of 2.5 to 3.5.

Hydroxylamine Hydrochloride acts as a powerful reducing agent and imaging agent. It is widely used in the pharmaceutical industry for synthesizing sulfanilamide drugs and antibiotics. In the rubber industry, it serves as a non-staining short-stop agent for synthetic rubber. Additionally, it is critical in analytical chemistry for the determination of copper, iron, and magnesium, and in the textile industry as a dyeing auxiliary.

As a hazardous chemical (Class 8 Corrosive), it must comply with the Globally Harmonized System (GHS) for labeling and packaging. Suppliers must provide a comprehensive Material Safety Data Sheet (MSDS). For European markets, REACH registration is essential. Ensure the supplier adheres to ISO 9001:2015 for quality management and ISO 14001 for environmental standards to mitigate regulatory risks.

The product is hygroscopic (absorbs moisture) and sensitive to light. It should be packed in plastic-lined fiber drums (25kg standard) or UV-resistant PE bags. Storage must be in a cool, dry, and well-ventilated warehouse, strictly separated from oxidizing agents, alkalis, and edible chemicals. Ensure the packaging is hermetically sealed to prevent caking and degradation.

This product is classified under UN Number 3335 or 2811 (depending on concentration and form) and requires UN-certified packaging. When sourcing from Made-in-China.com, verify that the supplier has a Dangerous Goods Export License. Shipping usually requires a 'Certificate for Safe Transport of Chemical Goods' issued by recognized bodies like DGM to facilitate smooth customs clearance.

Utilize Trade Assurance services to protect payments until delivery is confirmed. It is highly recommended to appoint a third-party inspection agency (such as SGS or BV) to conduct pre-shipment sampling and testing. This ensures the chemical composition matches the agreed-upon specifications before the balance payment is released.

Chemical prices are heavily influenced by raw material costs (e.g., Nitromethane or Ammonia) and environmental tax policies. Negotiate based on volume-based pricing tiers; for example, ordering in Full Container Loads (FCL) can reduce unit costs by 10-15% compared to LCL. Request a price validity period (usually 7-14 days) to protect against sudden market fluctuations during the procurement cycle.

Buyers must check their local import permit requirements, as some countries categorize hydroxylamine derivatives as precursor chemicals for controlled substances. Ensure the HS Code (typically 282510) is correctly declared to avoid anti-dumping duties or customs seizures. Always align with Incoterms 2020 (preferably CIF or DAP) to clearly define the point of risk transfer.
