About Dongding Industry Co., Ltd. - Chemicals & Allied Products Supplier in China

Dongding Industry Co., Ltd. is based in China and lists eight active chemical products in its catalogue. The company classifies its offerings under the Chemicals & Allied Products and Caustic Soda categories, covering both inorganic acids and sodium compounds. Products include Formic Acid (HS 2915.11), Oxalic Acid (HS 2917.11), Methylene Chloride (HS 2903.12), Sodium Nitrate (HS 3102.30), Sodium Nitrite (HS 2834.10), Caustic Soda Flakes and Pearls (both HS 2815.11), and Trichloroethylene with no HS code disclosed. Each listed material specifies purity levels, such as 99.99 % for Methylene Chloride and 99 %+ for Sodium Nitrate, indicating industrial‑grade standards. The catalogue focuses on aqueous solutions, inorganic salts, and halogenated solvents commonly used in manufacturing and laboratory settings.

The eight items span HS code families 2815, 2834, 2903, 2915, 2917 and 3102, reflecting typical tariff classifications for alkaline, nitrate, and organic solvent chemicals. Dongding’s product set includes both solid (flakes, pearls) and liquid (aqueous solutions, solvents) forms, providing flexibility for downstream processing. While the supplier’s trust tier is listed as “harbor,” no specific certifications are mentioned in the provided data. Buyers can therefore expect standard industrial specifications but should verify compliance with any required import regulations. The catalogue does not reference additional services such as blending or packaging beyond the described material forms.

Product Range and Specialties of Dongding Industry Co., Ltd.

Dongding’s catalogue presents Formic Acid as an aqueous solution of methanoic acid (HCOOH) and Oxalic Acid as the dihydrate C₂H₂O₄·2H₂O, both falling under HS 2915.11 and 2917.11 respectively. Methylene Chloride is offered at 99.99 % purity, a typical industrial grade used for paint stripping and extraction, while Trichloroethylene, though listed without an HS code, is a chlorinated solvent commonly classified under HS 2905. The sodium compounds include Sodium Nitrate (NaNO₃, >99 % purity) and Sodium Nitrite (NaNO₂), standard inputs for fertilizer and food preservation, classified under HS 3102.30 and 2834.10. Caustic Soda appears in two physical forms - flakes and pearls - both under HS 2815.11, with a minimum purity of 99 %, matching the specifications required for pulp‑and‑paper, textiles, and chemical synthesis.

In the broader chemicals market, Formic Acid is typically supplied at concentrations of 85 % - 99 % with specifications for purity and water content. Oxalic Acid dihydrate is usually graded as 99 % purity for analytical and industrial use. Methylene Chloride and Trichloroethylene are regulated for volatile organic compound (VOC) emissions, and buyers often request a Certificate of Analysis (CoA) confirming purity, boiling point, and density. Sodium Nitrate and Sodium Nitrite are shipped in bulk bags or drums, with standard moisture limits below 1 % and particle size specifications for uniform flow. Caustic Soda flakes and pearls are distinguished by particle size distribution; flakes are typically 2 - 5 mm, while pearls range 1 - 3 mm, affecting dissolution rates in process streams.

Trade and Export Information - Dongding Industry Co., Ltd.

Chinese chemical exporters such as Dongding commonly ship to Southeast Asia, the Middle East, and Europe, where demand for industrial solvents, alkaline reagents, and nitrate salts remains strong. HS code 2815 (Caustic Soda) often attracts buyers in the pulp‑and‑paper and metal treatment sectors, while HS 2903 (Methylene Chloride) and HS 2905 (Trichloroethylene) are regulated under REACH in the EU and may require pre‑export testing for residual chlorinated compounds. Typical incoterms include FOB Shanghai or CIF Rotterdam, with 20‑ft containers holding up to 20 tons of solid salts and 22 tons of liquids in drums. Export documentation usually includes a commercial invoice, packing list, Material Safety Data Sheet (MSDS), and where applicable, a Certificate of Origin.

Importers frequently request ISO 9001 quality management certification, REACH registration for organic solvents, and compliance with the Globally Harmonized System (GHS) for labeling. Although Dongding’s facts do not list any certifications, buyers should ask for the latest CoA, MSDS, and any third‑party testing reports (e.g., SGS, Bureau Veritas). Chinese exporters also follow the Ministry of Ecology and Environment’s guidelines for hazardous chemicals, which may affect packaging (e.g., UN‑rated drums) and transport labeling. Understanding these requirements helps mitigate customs delays and ensures that the chemicals meet the regulatory standards of the destination market.

Sourcing from Dongding Industry Co., Ltd. - Buyer Guidance

When sourcing from Dongding, buyers should request a Certificate of Analysis for each chemical, confirming purity, water content, and any residual solvents. For the caustic soda flakes and pearls, verify particle size distribution and moisture level, as these affect dissolution efficiency in process applications. Organic solvents such as Methylene Chloride and Trichloroethylene typically require an MSDS and, for EU destinations, a REACH compliance statement before shipment.

Buyers should also confirm packaging details: bulk chemicals are often packed in 200‑kg IBCs or 25‑kg drums, while solid salts may be shipped in 1‑ton polypropylene bags. It is prudent to ask for a sample batch and a test report from an accredited laboratory to validate the declared specifications. Finally, ensure that the supplier can provide the necessary export documentation, including a Certificate of Origin, to satisfy customs clearance in the target market.
