Smiletech — Verified Supplier
About Smiletech - Water Treatment Chemicals Supplier in Viet Nam
Viet Nam based Smiletech lists twelve active products across water treatment chemicals, industrial chemicals and dried fruit. The catalogue includes multiple forms of poly aluminium chloride (PAC) such as liquid, 30 % solution and polymer grades, as well as aluminium sulphate powder, chlorine gas and a 31 % hydrochloric acid. In the industrial chemicals segment the company also offers a reddish‑solution vial powder that is marketed for treatment processes. The food segment is represented by a single item, dried dragon fruit, which is listed alongside the chemical range. All entries are grouped under the broader categories of water treatment chemicals, industrial chemicals and fruit products, reflecting a diversified product portfolio.
The twelve products are identified by their functional names rather than brand codes, for example “Water Treatment Poly Aluminium Chloride Liquid” and “Aluminium Sulphate Powder Industrial Grade White”. The chemical list contains both liquid and solid PAC formulations, a chlorine gas product and a concentrated hydrochloric acid, each typical of water‑treatment plant inventories. The dried dragon fruit is the only non‑chemical item and is presented as a processed fruit commodity. No additional product specifications, such as HS codes or certifications, are provided in the source data.
Product Range and Specialties of Smiletech
Smiletech’s catalogue features several grades of poly aluminium chloride (PAC), a coagulant commonly supplied at 30 % active aluminium concentration and packaged in 25 kg drums or bulk containers. Industry practice for PAC includes purity specifications of ≥ 99 % Al₂O₃ and a cloud point below 20 °C, with standard test methods such as ASTM D 2775. Aluminium sulphate is typically offered as a white powder of 98 % purity, used for pH adjustment and flocculation, and is shipped in 20‑ft containers or 1‑ton bags. Chlorine gas is usually supplied at 99.5 % purity in pressurised cylinders, complying with UN 1011 regulations, while hydrochloric acid at 31 % is graded for industrial use with corrosion‑resistance testing. The dried dragon fruit is generally processed to a moisture content below 10 % and packed in food‑grade polyethylene bags of 20 kg, meeting HACCP guidelines.
Trade and Export Information - Smiletech
Vietnam is a major exporter of water‑treatment chemicals, with shipments of PAC, aluminium sulphate and chlorine gas commonly directed to Southeast Asian water utilities, Indian industrial parks and European treatment facilities. HS chapter 28 (inorganic chemicals) covers most of Smiletech’s chemical products: PAC falls under 2825, aluminium sulphate under 2833, chlorine gas under 2804 and hydrochloric acid under 2807. Buyers typically request ISO 9001 quality‑management certificates, REACH compliance documents for the EU market, and safety data sheets (SDS) for each chemical. Packaging for bulk chemicals follows standard ISO containers (ISO‑T containers for liquids, bulk bags for powders) and freight is usually quoted on FOB or CIF terms. Dried tropical fruits from Vietnam are classified under HS 0810 and are exported mainly to North America, the EU and Middle‑East markets, where phytosanitary certificates and GMP compliance are standard requirements.
Sourcing from Smiletech - Buyer Guidance
When sourcing PAC or aluminium sulphate from Smiletech, request a Certificate of Analysis that confirms active aluminium concentration, impurity levels and pH stability. For chlorine gas and hydrochloric acid, obtain a complete Safety Data Sheet and a compliance statement for UN 1011 and REACH regulations. The buyer should verify container integrity, especially for pressurised chlorine cylinders, and confirm that the packaging meets the destination country’s hazardous‑material handling rules. For the dried dragon fruit, ask for a moisture‑content test report, a pesticide residue analysis and a HACCP‑type food safety certificate before confirming a shipment. Typical minimum order quantities in the chemical segment range from 1 ton for powdered products to 5 tons for liquid PAC, while fruit orders often start at 500 kg.
