About Dalian Chem Imp.& Exp. Group Co., Ltd - Silica Gel Supplier in China

China, Dalian - Dalian Chem Imp.& Exp. Group Co., Ltd lists five active chemical products in its catalogue. The portfolio includes silica gel, zinc oxide, caustic soda flake/sold/pearls, maleic anhydride briquettes and flakes, and carbon molecular sieve (CMS). Silica gel is offered as a desiccant material, while zinc oxide is presented as an inorganic white powder. Caustic soda appears in flake, solid, and pearl forms for various alkaline applications. Maleic anhydride is supplied in both briquette and flake formats, and CMS is listed for gas separation uses.

The supplier is classified as an imported tier with a harbor trust tier, indicating it operates primarily as an intermediary for overseas procurement. All five products fall under standard chemical HS code families used for bulk chemical trade, though specific codes are not disclosed in the catalogue. The product range covers both inorganic oxides and organic anhydrides, reflecting a focus on industrial chemicals used in manufacturing, water treatment, and petrochemical processing. Buyers can expect the listed items to be handled in bulk shipments such as 20‑ft or 40‑ft containers, typical for Chinese chemical exporters. The catalogue does not provide detailed specifications, leaving verification to the buyer.

Product Range and Specialties of Dalian Chem Imp.& Exp. Group Co., Ltd

The catalogue lists silica gel, zinc oxide, caustic soda (flake, solid, pearls), maleic anhydride (briquettes and flakes) and carbon molecular sieve (CMS). In the global market silica gel is commonly graded as 4A, 13X or 60 mesh, with moisture content usually below 5 % and particle sizes from 0.5 to 2 mm. Zinc oxide is typically supplied at 99.5 % purity or higher, with a median particle size around 5 µm and is used in rubber, ceramics and cosmetics. Caustic soda in flake or pearl form is usually 99 % pure, moisture below 2 %, and shipped in HDPE drums or bulk bags for chemical processing. Maleic anhydride briquettes and flakes are generally 99 % pure, stored in sealed containers to avoid moisture uptake, and serve as intermediates for polyester resins. Carbon molecular sieve is offered for gas separation, with pore sizes near 0.5 nm, adsorption capacities of 150 - 200 mg g‑1, and purity often exceeding 99.5 %.

Trade and Export Information - Dalian Chem Imp.& Exp. Group Co., Ltd

China remains one of the world’s largest exporters of bulk chemicals, and the listed products are routinely shipped to industrial users in Southeast Asia, Europe, and North America. Exporters of silica gel, zinc oxide, caustic soda, maleic anhydride and CMS usually file under HS‑4 chapters 38 (organic chemicals) and 28 (inorganic chemicals), and customs authorities often request a Material Safety Data Sheet (MSDS) and a Certificate of Analysis for each shipment. Buyers in the EU typically require REACH registration or an import authorization, while North American importers look for compliance with TSCA and EPA regulations. Standard logistics involve 20‑ft or 40‑ft containers, with FOB Dalian or CIF major ports such as Shanghai; bulk drums or flexible intermediate bulk containers (FIBCs) are common packing formats. Quality certifications such as ISO 9001, ISO 14001 or specific industry standards are frequently requested by importers to verify consistent production processes.

Sourcing from Dalian Chem Imp.& Exp. Group Co., Ltd - Buyer Guidance

When sourcing from this supplier, request an up‑to‑date MSDS and a third‑party Certificate of Analysis that details purity, moisture content and particle size for each chemical. Ask for evidence of any applicable certifications - for example ISO 9001 for the manufacturing system, REACH compliance for EU shipments, or TSCA pre‑manufacture notice for the United States. Verify packaging details (e.g., 200 L HDPE drums for caustic soda, 25 kg paper bags for silica gel) and confirm that the containers meet UN hazardous‑materials regulations if required. Typical minimum order quantities for bulk chemicals from Chinese exporters range from 5 to 20 metric tonnes, with lead times of 30 - 45 days after order confirmation. Ensure that the supplier can provide inspection reports from recognized agencies such as SGS or Bureau Veritas before loading.

What form does silica gel come in from Dalian Chem?

The catalogue lists silica gel without a specified shape, but industry practice is to supply it as granules or beads ranging from 0.5 mm to 2 mm in size, suitable for bulk desiccant applications.

Is zinc oxide supplied with a purity specification?

The supplier’s listing does not include a purity figure; buyers should request a Certificate of Analysis stating purity, typically 99.5 % or higher for industrial zinc oxide.

How is caustic soda packaged for export?

Caustic soda is offered as flake, solid and pearl forms; exporters normally use 200 L HDPE drums, 25 kg paper bags, or bulk containers, and the buyer should confirm the exact packaging before ordering.

What documentation is needed for maleic anhydride imports?

Importers generally require an MSDS, a Certificate of Analysis, and, for EU destinations, proof of REACH registration or an import notification.

Can I obtain a sample of the carbon molecular sieve?

Yes, most Chinese chemical exporters provide a small sample (e.g., 500 g) of CMS for testing; request the sample together with the COA and pore‑size data.

What are the typical Incoterms used by this supplier?

Chinese chemical exporters commonly quote FOB Dalian or CIF Shanghai, allowing the buyer to choose the most suitable logistics arrangement.

Are there any standard certifications I should verify before purchase?

Buyers should verify ISO 9001 for quality management, any relevant environmental certifications, and request third‑party inspection reports (SGS, Intertek, etc.) to confirm compliance with product specifications.

What is the usual lead time for a bulk order?

Lead times for the listed chemicals are generally 30 to 45 days after order confirmation, depending on production scheduling and container availability.
