Import Acid Chlohydric 31% Made In Vietnam — Buy in wholesale FOB from Supplier in Viet Nam

Smiletech supplies hydrochloric acid at 31% concentration, a colourless to slightly yellowish corrosive solution with formula HCl and CAS number 7647-01-0, manufactured in Vinh Phuc province, Vietnam. The product carries EINECS 231-595-7 registration and is classified as a chemical auxiliary agent for water treatment applications. At 31% concentration, this material sits at the azeotropic composition for atmospheric pressure HCl solutions, making it stable against concentration drift during storage and transport under standard conditions.

The manufacturing process typically involves hydrogen chloride gas absorption in demineralised water, with quality controlled by iron content, sulfate content, and free chlorine specifications. Smiletech's stated iron content is 5.0 ppm maximum, sulfate as SO4²⁻ at 200.0 ppm maximum, and free chlorine at 30 ppm maximum. These impurity levels indicate technical-grade material suitable for water treatment, pH adjustment, and industrial cleaning rather than pharmaceutical or food-grade applications. Standard packaging for this concentration includes IBC tanks for bulk supply and 25-litre drums for smaller quantities, though exact net weights and UN-certified container specifications require direct confirmation.

Primary applications span municipal and industrial water treatment, metal surface pickling, textile processing, and chemical synthesis where controlled acidity is required. The 31% strength offers handling advantages over fuming grades while minimising transport water content. Buyers should verify with Smiletech whether their production capacity supports scheduled delivery programmes or spot-only supply, and whether they provide material safety data sheets compliant with destination country regulations. The Harbor trust tier and zero response rate indicate all transaction terms, lead times, and certification scope must be negotiated directly rather than through automated channels.

Smiletech operates from 172a Yen Lang Street, Thinh Quang Ward, Dong Da District, Hanoi, 100000, Vietnam, with production stated to occur in Vinh Phuc province north of the capital. The supplier holds Harbor trust. trust tier status, indicating basic marketplace profile presence without enhanced verification. No response rate or average response time data is recorded, which signals that digital enquiry channels may not yield prompt replies and direct contact methods should be pursued for urgent procurement needs.

The company markets under the Vietchem brand for this product line, though the relationship between Smiletech as supplier and Vietchem as brand requires clarification directly with them. No manufacturing facility details, production capacity, year of establishment, employee count, or named reference customers appear in available data. Their product description classifies the material as molecular sieve adsorbent variety, which appears to be a categorisation error given HCl's true classification as a strong inorganic acid, buyers should confirm the actual intended application scope and regulatory compliance status with Smiletech before finalising specifications.
