Tianjin Ruihaiweilin Chem Co.Ltd — Verified Supplier
About Tianjin Ruihaiweilin Chem Co.Ltd - Titanium Dioxide Supplier in China
Tianjin Ruihaiweilin Chem Co.Ltd is based in Tianjin, China and lists five active products in its catalogue. The supplier is classified as an imported tier with a harbor trust tier, indicating that its goods are typically shipped through major Chinese ports. Its top categories are Titanium Dioxide, Sodium Hydroxide and Calcium Chloride, which are all inorganic chemical products falling under HS Chapter 28. The company’s catalogue also includes Sodium Tripolyphosphate and Aluminum Sulphate, completing the five‑product offering.
The listed products cover a range of industrial chemicals used in pigments, water treatment, detergent formulation and de‑icing. Each product is identified by its generic chemical name without further branding, and the catalogue groups them under the broader categories of pigments, alkali chemicals and inorganic salts. The supplier’s focus on these categories aligns with China’s large-scale production of basic inorganic chemicals for global markets.
Product Range and Specialties of Tianjin Ruihaiweilin Chem Co.Ltd
The catalogue contains Titanium Dioxide, Sodium Hydroxide, Sodium Tripolyphosphate, Calcium Chloride and Aluminum Sulphate. In the global market Titanium Dioxide is commonly supplied in rutile or anatase grades such as CI 77007, with purity levels typically above 99.5 % and particle size distributions expressed in micrometres. Sodium Hydroxade is usually offered as technical grade with ≥99 % NaOH content, often in solid flakes or pellets. Sodium Tripolyphosphate is frequently sold as a detergent‑grade powder with ≥99 % purity and a moisture content below 2 %. Calcium Chloride is exported in de‑icing grades ranging from 96 % to 99 % CaCl₂, supplied as granules or flakes, while Aluminum Sulphate is generally provided as a water‑treatment grade with ≥98 % Al₂(SO₄)₃·18H₂O content.
Typical packaging for these chemicals includes 25 kg polypropylene bags for smaller orders and bulk bulk‑handling options such as 1 ton or 20‑ft container loads. Buyers often specify moisture limits, particle size (for TiO₂) or bulk density (for CaCl₂) in their purchase specifications, and the supplier’s product list aligns with those standard industry parameters.
Trade and Export Information - Tianjin Ruihaiweilin Chem Co.Ltd
China is one of the world’s leading exporters of inorganic chemicals, and Tianjin’s port facilities handle a high volume of bulk and bagged shipments. Products in this catalogue are usually shipped under FOB Tianjin or CIF major destination ports in Europe, Southeast Asia and North America. The HS‑code family for these items resides in Chapter 28 (Inorganic Chemicals), which is subject to standard customs documentation, including a commercial invoice, packing list and a material safety data sheet (MSDS).
Buyers importing these chemicals commonly require certifications such as ISO 9001 quality management, REACH registration for the European Union, and a Certificate of Origin to benefit from preferential duties. Additional documents that customs authorities may request include a test report for purity, particle size analysis for TiO₂, and a water content test for salts. Export controls in China for certain grades of Sodium Hydroxide and Titanium Dioxide are managed through the Ministry of Commerce, so a valid export license is typically part of the shipping paperwork.
Sourcing from Tianjin Ruihaiweilin Chem Co.Ltd - Buyer Guidance
When sourcing from Tianjin Ruihaiweilin Chem Co.Ltd, buyers should request a current Certificate of Analysis (CoA) that details purity, moisture, particle size (for TiO₂) and any residual metal limits. An up‑to‑date MSDS is essential for handling and transport compliance, and buyers often ask for a REACH‑compliant declaration if the destination is the EU. Verifying the supplier’s ISO 9001 certification, if available, adds an extra layer of quality assurance.
Typical minimum order quantities for bulk inorganic chemicals range from 1 metric ton to a full 20‑ft container load, with lead times of four to six weeks after order confirmation. Packaging should be inspected for integrity; sealed 25 kg bags are standard for smaller shipments, while bulk containers require inner liners to prevent moisture ingress. Confirming the Incoterm (FOB Tianjin or CIF) and ensuring that the export license covers the specific grade requested will help avoid customs delays.
