About Yangzhou Guanmin Detergent Chemicals Co., Ltd. - Detergent Chemicals Supplier in China

Yangzhou Guanmin Detergent Chemicals Co., Ltd. is located in Yangzhou, China and lists 14 active detergent‑related products. The catalogue covers synthetic zeolite builders such as Zeolite 4A Detergent Grade (HS 3824.90) and Zeolite Detergent Grade (HS 2842.10), sodium silicate based builders including Modified Sodium Disilicate (HS 2839.19) and Complex Sodium Disilicate (HS 2835.39, 3402.90). It also offers anionic surfactants like Sodium Lauryl Ether Sulphate (SLES) (HS 3402.11) and a fluorescent whitening agent CBS‑X (HS 3204.20). Additional items include Carboxymethylcellulose Sodium (CMC) for liquid detergents (HS 3912.31) and enzyme blends for liquid detergent and dishwash applications.

The product list further contains STPP substitute options based on zeolite A, a Best STPP Substitute (HS 2835.39) and a Complex Sodium Disilicate - best STPP substitute (HS 2839.19). Two entries for Sodium Lauryl Ether Sulphate appear without HS codes, reflecting the same anionic surfactant chemistry. The catalogue also mentions phosphate‑free detergent builders and mixed enzyme systems, providing a comprehensive set of ingredients used in industrial and household detergent formulations.

Product Range and Specialties of Yangzhou Guanmin Detergent Chemicals Co., Ltd.

The catalogue includes Zeolite 4A Detergent Grade (synthetic Na12Al12Si12O48·27H2O, HS 3824.90) which in the industry is typically supplied with particle sizes of 3 - 5 µm, moisture below 5 % and purity > 99 %. Modified Sodium Disilicate (HS 2839.19) is usually sold with a Na2O/SiO2 ratio of 1:2 and a bulk density around 1.4 t/m³. Sodium Lauryl Ether Sulphate (SLES) listed under HS 3402.11 is commonly offered as a 30 % - 40 % active liquid, with an anionic surfactant content measured by titration and a cloud point below 30 °C. CBS‑X, a stilbene‑derived fluorescent whitening agent (HS 3204.20), is normally supplied at 0.1 % - 0.5 % concentration with a spectral emission peak near 440 nm. CMC Sodium (HS 3912.31) is provided as a powder with a degree of substitution around 0.7 and a viscosity of 5000 - 15000 cP at 1 % solution.

Industry practice for detergent builders such as zeolite A (STPP substitute) and complex sodium disilicate includes bulk packaging in 20‑ft containers, 25 kg drums or 1‑ton polyethylene bags, with moisture barriers to preserve performance. Enzyme blends for liquid detergent and dishwash are usually supplied as liquid concentrates with activity expressed in protease units per gram, and require cold‑chain handling below 25 °C. Buyers often request compliance with REACH registration, a Material Safety Data Sheet (MSDS), and a Certificate of Analysis (CoA) that confirms the stated purity, particle size distribution, and pH range.

Trade and Export Information - Yangzhou Guanmin Detergent Chemicals Co., Ltd.

China ranks among the world’s largest exporters of detergent chemicals, and the HS‑code families represented in this catalogue (3824, 2839, 2842, 3204, 3402, 3912) are routinely shipped to East Asia, Southeast Asia, Europe and North America. Importers typically require REACH registration, an ISO‑9001 quality management system and a GHS‑compliant MSDS. Bulk shipments are most often packed in 20‑ft or 40‑ft containers, using moisture‑proof bags for zeolites and sealed drums for liquid surfactants; FOB and CIF terms are common in contracts.

Regulatory bodies such as the US EPA, EU ECHA and China’s AQSIQ inspect the declared HS codes, material safety data and test reports before customs release. For surfactants like SLES, buyers frequently request a cloud‑point test and anionic surfactant content by titration. Zeolite builders are subject to particle‑size analysis (laser diffraction) and moisture content determination (Karl Fischer). Export from China benefits from established port facilities in Shanghai and Ningbo, with typical transit times of 20‑30 days to Europe and 12‑18 days to the United States.

Sourcing from Yangzhou Guanmin Detergent Chemicals Co., Ltd. - Buyer Guidance

When sourcing from this supplier, request a current Material Safety Data Sheet, a Certificate of Analysis and, where applicable, REACH registration documents for each product. Verify the zeolite grades by confirming particle‑size distribution, moisture content and purity percentages; for SLES ask for active‑content titration results and cloud‑point data. Enzyme concentrates should be accompanied by activity units per gram and storage‑temperature specifications.

Typical minimum order quantities in the detergent‑chemical segment range from 1 metric ton for bulk powders to 500 kg for specialty liquids, with lead times of 30‑45 days after order confirmation. Confirm packaging details - e.g., 25 kg drums for liquid surfactants or 1‑ton polyethylene bags for zeolites - and ensure the supplier can provide ISO‑9001 or ISO‑14001 certification upon request. Samples of 5 - 10 kg for powders or 10 L for liquids are customary for performance testing before full‑scale purchase.

What detergent‑chemical products does Yangzhou Guanmin list in its catalogue?

The catalogue contains 14 items, including Zeolite 4A Detergent Grade (HS 3824.90), Zeolite Detergent Grade (HS 2842.10), Modified Sodium Disilicate (HS 2839.19), Complex Sodium Disilicate (HS 2835.39 and 3402.90), Sodium Lauryl Ether Sulphate (HS 3402.11), CBS‑X fluorescent whitening agent (HS 3204.20), CMC Sodium (HS 3912.31) and mixed enzyme blends for liquid detergent and dishwash.

Which HS codes are associated with the listed products?

Relevant HS codes are 3824.90 for Zeolite 4A, 2842.10 for Zeolite Detergent Grade, 2839.19 for Modified Sodium Disilicate and Complex Sodium Disilicate, 2835.39 for the Best STPP Substitute, 3402.11 for Sodium Lauryl Ether Sulphate, 3204.20 for CBS‑X, and 3912.31 for CMC Sodium. Products without an HS code in the catalogue should be clarified with the supplier.

What typical specifications should I verify for zeolite builders?

Buyers usually check particle size (3 - 5 µm), moisture content (< 5 %), purity (> 99 %), and bulk density (~1.4 t/m³). A Certificate of Analysis should confirm these parameters and the chemical formula Na12Al12Si12O48·27H2O.

How is the quality of Sodium Lauryl Ether Sulphate measured?

SLES quality is assessed by anionic surfactant content (30 % - 40 % active), cloud‑point temperature (below 30 °C) and pH of a 1 % solution (typically 7 - 9). A CoA should include titration results and visual clarity data.

Are there any standard certifications buyers should request for these chemicals?

Typical certifications include ISO‑9001 for quality management, ISO‑14001 for environmental management, REACH registration for the EU market, and a GHS‑compliant MSDS. The supplier’s own certifications, if any, must be confirmed directly.

What are common packaging formats for the listed products?

Bulk powders such as zeolites and sodium disilicates are usually packed in 1‑ton polyethylene bags or 25 kg drums; liquid surfactants and enzyme concentrates are shipped in 200 L or 500 L steel drums, and small‑scale samples are provided in 5 kg bags or 10 L containers.

What are typical MOQ and lead time for orders?

Minimum order quantities generally start at 1 metric ton for bulk powders and 500 kg for liquids. Lead times after order confirmation are typically 30‑45 days, depending on product availability and required packaging.

Which regions most frequently import these detergent chemicals from China?

Major import regions include Southeast Asia, the European Union, North America and the Middle East. Buyers in these markets often require the same HS‑code declarations, REACH compliance and customs documentation for smooth clearance.
