It is a solution of hydrogen fluoride in water, known for its unique ability to etch glass and react with silica compounds. Unlike other mineral acids, HF is a weak acid in dilute solutions but possesses extreme toxicity and reactivity, making it a critical yet dangerous chemical in industrial applications. Its primary uses include the production of fluorocarbons, aluminum smelting (as a precursor to aluminum fluoride), petroleum alkylation, uranium processing, and semiconductor etching. The global hydrofluoric acid market is driven by demand from the refrigeration, electronics, and automotive industries, with stringent safety regulations governing its production and handling.<\/p>\n<h2 id=\"toc-82542e09f78a12e16bf5bc61fa7ead5e\">Global Top 10 Hydrofluoric Acid Suppliers and Factories<\/h2>\n<p>The global HF market is dominated by large chemical conglomerates and specialized manufacturers.

For electronic-grade HF, look for SEMI standards compliance. Request Material Safety Data Sheets (MSDS) and batch analysis reports before purchase.<\/p>\n<h3 id=\"toc-fede2836112f08e7a3e013417ddd73d7\">Production Capacity and Consistency<\/h3>\n<p>Verify annual output and ability to scale. Large plants like Zhejiang Juhua offer consistent supply, while smaller factories may have variability. Request production schedules and third-party lab test results.<\/p>\n<h3 id=\"toc-10fd97d2c797234f4c15c9de0df1fec3\">Safety and Regulatory Compliance<\/h3>\n<p>Chinese manufacturers must comply with the &#8220;Regulations on the Safety Management of Hazardous Chemicals.&#8221; Check for valid production licenses, hazardous chemical permits, and export registration. Non-compliance can lead to shipment delays.<\/p>\n<h3 id=\"toc-bbf1638f673db4094afe28448d16710c\">Logistics and Packaging<\/h3>\n<p>HF requires specialized packaging (HDPE drums, IBC totes, ISO tanks).

Filter by &#8220;Manufacturer&#8221; and request samples. Ensure the supplier has a valid hazardous chemical export license.<\/li>\n<li><strong>Q: What is the price of hydrofluoric acid per ton in 2025?<\/strong> A: Industrial grade (70%) costs $1,200\u2013$1,500\/MT FOB China. Anhydrous grade is $2,000\u2013$2,500\/MT. Prices fluctuate with fluorspar costs and shipping rates.<\/li>\n<li><strong>Q: How to ship hydrofluoric acid internationally?<\/strong> A: Use UN-approved HDPE drums or ISO tanks. Classify as UN1790, Class 8, PG I. Hire a freight forwarder specializing in hazardous chemicals. Sea freight is mandatory.<\/li>\n<li><strong>Q: Is hydrofluoric acid legal to import in my country?<\/strong> A: Check local regulations. Most countries require an import permit for hazardous chemicals. The US EPA and EU REACH have specific registration requirements.<\/li>\n<li><strong>Q: What is the difference between 49% and 70% HF?<\/strong> A: 49% HF is commonly used for etching and cleaning, while 70% is used in chemical synthesis. Higher concentration requires stricter handling due to increased fuming.<\/li>\n<li><strong>Q: How to test hydrofluoric acid purity at home?<\/strong> A: Professional testing requires titration or ICP-MS. Do not attempt home testing due to toxicity. Request a certificate of analysis from the supplier.<\/li>\n<li><strong>Q: Can I get a sample of hydrofluoric acid before bulk purchase?<\/strong> A: Yes, most suppliers offer 1\u20135 kg samples for $100\u2013$300, including shipping. Ensure proper packaging and labeling for small quantities.<\/li>\n<li><strong>Q: What are the risks of buying cheap HF from China?<\/strong> A: Risks include low purity, contamination, and non-compliance with safety standards. Always verify the supplier&#8217;s certifications and request third-party testing.<\/li>\n<li><strong>Q: How to store hydrofluoric acid safely?<\/strong> A: Store in HDPE containers in a cool, dry, ventilated area away from metals and bases. Use secondary containment. Temperature should not exceed 30\u00b0C.<\/li>\n<li><strong>Q: What is the lead time for HF orders from China?<\/strong> A: Typical lead time is 2\u20134 weeks for bulk orders (20 MT+). Sample orders ship within 1 week.
