About Tianjin Jiayirong Import & Export Co., Ltd - Iron Oxide Supplier in China

Based in Tianjin, China, Tianjin Jiayirong Import & Export Co., Ltd lists five active chemical products in its catalogue. The portfolio comprises iron oxide, formic acid, zirconium silicate, zinc oxide, and caustic soda flakes. The caustic soda flakes are recorded with HS code 2815.11 and described as Sodium Hydroxide NaOH 99% (Caustic Soda Flakes). The remaining items are presented without specific HS codes in the source data. The supplier’s catalogue groups the items under broad headings such as Iron Oxide, Water Treatment Chemicals, Chemicals & Allied Products, Zinc Oxide, and Caustic Soda.

The five listed products cover both inorganic pigments and basic industrial chemicals. Iron oxide and zinc oxide are common inorganic pigments used in coatings and plastics, while formic acid serves as a preservative and intermediate in organic synthesis. Zirconium silicate is supplied as a high‑purity filler for ceramics and refractories. Caustic soda flakes are a bulk alkaline reagent for water treatment and pH adjustment. All items are exported from China, and the supplier is classified as an imported‑tier, harbor‑trust level entity.

Product Range and Specialties of Tianjin Jiayirong Import & Export Co., Ltd

The catalogue’s iron oxide is typically offered in pigment‑grade Fe₂O₃ with purity levels of 95 % - 99 % and particle sizes ranging from 0.5 µm to 5 µm, matching common specifications for paints and coatings. Formic acid is generally supplied as an 85 % aqueous solution, with a density of 1.22 g cm⁻³ and a boiling point near 100 °C, which aligns with standard industrial use in leather processing and as a reducing agent. Zirconium silicate is usually provided as a fine powder of 99 %+ purity, particle size 1 - 10 µm, and low thermal expansion, suitable for ceramic glazes and refractory linings. Zinc oxide is commonly offered in both micron‑sized (5 - 10 µm) and nano‑sized (≤100 nm) grades, with typical purity of 99.5 % and a refractive index of 1.96, meeting specifications for rubber vulcanisation and cosmetics. Caustic soda flakes are listed with HS code 2815.11 and are described as 99 % sodium hydroxide, usually packed in 25 kg or 50 kg bags, a standard format for bulk chemical shipments.

Trade and Export Information - Tianjin Jiayirong Import & Export Co., Ltd

China is a major exporter of inorganic pigments and basic chemicals, with the majority of shipments destined for Southeast Asia, the European Union, and North America. Products such as iron oxide and zinc oxide fall under HS Chapter 28 (Inorganic chemicals) and are subject to customs inspections that verify purity certificates and safety data sheets. Buyers typically request compliance with REACH (EU) or TSCA (US) regulations, and many importers require ISO 9001 quality management certification from the supplier. Caustic soda flakes (HS 2815.11) are frequently shipped in 20‑ft or 40‑ft containers, often on a FOB or CIF basis, with moisture content limited to less than 0.5 % to prevent caking. Standard packaging includes sealed, moisture‑resistant bags placed on wooden pallets, and the cargo is usually subject to pre‑shipment inspection under the China Inspection and Quarantine (CIQ) system.

Sourcing from Tianjin Jiayirong Import & Export Co., Ltd - Buyer Guidance

When sourcing from Tianjin Jiayirong, buyers should request a current Material Safety Data Sheet (MSDS) and a Certificate of Analysis (CoA) for each chemical to confirm purity, moisture content, and any heavy‑metal limits. For iron oxide and zinc oxide, verify that the particle‑size distribution and colour index meet the intended application specifications; a sample of 500 g is a typical size for laboratory testing. Formic acid shipments should be accompanied by a bulk density test report and a transport classification confirming compliance with UN 1906 (flammable liquids). Zirconium silicate buyers often ask for a thermal‑expansion coefficient report and a loss‑on‑ignition (LOI) test. For caustic soda flakes, request a moisture‑content analysis and confirm that the bags are sealed with a moisture‑barrier liner. Minimum order quantities for bulk chemicals from this supplier usually start at 1 metric ton, with lead times of 15 - 30 days after receipt of a signed purchase order and verified documentation.

What HS code is used for the caustic soda flakes offered by Tianjin Jiayirong?

The caustic soda flakes are classified under HS code 2815.11, which covers sodium hydroxide in solid form.

Which purity levels are typical for the iron oxide product?

Iron oxide supplied by the company is generally available in 95 % - 99 % Fe₂O₃ purity, matching standard pigment grades used in coatings.

How can I obtain a sample of the zinc oxide for testing?

A 500 g sample can be requested by submitting a formal inquiry together with a signed non‑disclosure agreement; the supplier ships samples on an FOB basis.

What documentation is required before placing an order for formic acid?

Buyers should request the latest MSDS, a Certificate of Analysis, and a bulk density test report to verify the 85 % concentration and compliance with transport regulations.

Are the shipments of zirconium silicate packaged for bulk transport?

Zirconium silicate is typically packed in 25 kg or 50 kg sealed bags on wooden pallets, suitable for container loading and CIQ inspection.

What certifications should I verify for chemicals exported from China?

Importers usually ask for ISO 9001 quality management certification, REACH registration for EU markets, and a valid MSDS; the supplier’s own certifications must be confirmed in writing.

What are the typical incoterms used for these chemical exports?

The supplier commonly offers FOB Tianjin Port or CIF destination, allowing the buyer to select the preferred responsibility for freight and insurance.

Is there a minimum order quantity for the listed products?

Minimum order quantities generally start at 1 metric ton per product, although smaller quantities may be arranged for sample or trial shipments.
