About Guangzhou Chengshuai New Material Co., Ltd - Industrial Chemicals Supplier in China

Guangzhou Chengshuai New Material Co., Ltd is based in Guangzhou, China and lists 61 distinct chemical products. The company’s catalogue falls under the industrial chemicals segment, with additional listings in chemicals & allied products, stabilizers, and industrial machinery. Product entries are organized by HS‑code families such as 2907 (phenolic antioxidants), 2914 (photoinitiators), 2918 (UV absorbers), 2931 (phosphite antioxidants) and 3812 (vulcanizing agents). Each entry includes the chemical name, CAS number and, where provided, the molecular composition. The HS codes indicate that the goods are classified under Chapter 29 (organic chemicals) and Chapter 38 (miscellaneous chemical products).

The catalogue contains a range of antioxidants such as Antioxidant 626, 1135, 1425 and 1790, each identified by specific CAS numbers and material descriptions. UV‑absorbing additives include UV‑1, UV‑120, UV‑329, UV‑531 and UV‑571, covering benzotriazole and benzophenone chemistries. Photoinitiators listed include TPO‑L, BP, EMK and PBZ, which are typical for UV‑curable coatings. Additional items are a phosphite antioxidant DPD, a vulcanizing agent TB710 and several HALS (e.g., Antioxidant 565, Light Stabilizer LS‑5050H). All products are recorded with HS codes that align with their chemical function, enabling straightforward customs classification.

Product Range and Specialties of Guangzhou Chengshuai New Material Co., Ltd

The antioxidant portfolio covers hindered phenolic structures (e.g., Antioxidant 626, 1135) and phosphite‑based systems (DPD) that are widely used to inhibit thermal oxidation in polyolefins and rubber. In the industry, such antioxidants are specified by their oxidation onset temperature, typically above 180 °C, and by the required dosage ranging from 0.1 % to 0.5 % by weight. The HALS items (e.g., Antioxidant 565, Light Stabilizer UV3853PP5) provide long‑term UV resistance and are evaluated through light‑fade tests such as ASTM D4325. UV absorbers listed (UV‑1, UV‑120, UV‑329, UV‑531) belong to benzotriazole and benzophenone families, which absorb in the 300‑400 nm band and are commonly dosed at 0.2‑2 wt%. Photoinitiators such as TPO‑L, BP and EMK are aromatic ketones that initiate polymerisation under UV light, with typical cure rates measured in seconds at 365 nm.

All chemicals are supplied in standard industrial packaging, often 25 kg drums or 200 L IBCs, suitable for bulk shipments. The HS‑code assignments (e.g., 2931.90 for phosphite antioxidants, 2914.50 for benzophenone photoinitiators) align with global customs tariff schedules, facilitating clearance in major import markets. Buyers can expect purity levels of ≥ 98 % for most listed compounds, as indicated by the molecular formulas provided. The catalogue also includes a vulcanizing agent (TB710) that combines sulfur with organic accelerators, a formulation typical for tire and rubber compounding.

Trade and Export Information - Guangzhou Chengshuai New Material Co., Ltd

China ranks among the world’s largest exporters of organic chemicals, and products classified under HS chapters 29 and 38 are regularly shipped to Europe, North America, Southeast Asia and the Middle East. Buyers of antioxidants, UV absorbers and photoinitiators usually request compliance with REACH registration for the EU, TSCA certification for the United States, and safety data sheets (SDS) that meet GHS labeling. Common third‑party inspections include SGS or Intertek audits, and many importers require ISO 9001‑based quality management documentation. The HS codes present in this catalogue (e.g., 2907.19, 2914.39, 3812.39) fall under tariff rates that may be subject to anti‑dumping duties in certain jurisdictions. Export logistics from Guangzhou typically involve loading 20‑ft or 40‑ft containers, with bulk drums stacked on pallets to meet standard container weight limits.

Standard packaging for these chemicals includes sealed 25 kg drums, 200 L IBCs or 1 ton intermediate bulk containers, all with UN number labeling for hazardous substances where applicable. Incoterms such as FOB Guangzhou or CIF destination port are commonly used, allowing buyers to arrange customs clearance and inland transport. Documentation normally required includes commercial invoice, packing list, certificate of origin, and where applicable, a REACH registration number. Export controls in China mandate that the exporter holds the necessary export licenses for dual‑use chemicals, and buyers should verify that the supplier’s licenses cover the specific HS codes listed.

Sourcing from Guangzhou Chengshuai New Material Co., Ltd - Buyer Guidance

Prospective buyers should request a full safety data sheet for each chemical, confirming GHS hazard classifications, storage temperature limits and recommended personal protective equipment. For antioxidants and HALS, it is advisable to obtain thermal stability data (e.g., TGA or DSC curves) and dosage recommendations from the supplier’s technical data sheet. UV absorbers and photoinitiators typically require spectral absorption data (UV‑Vis) and cure rate testing results, which should be supplied before finalising a purchase. Verification of REACH registration numbers, TSCA status and any applicable EU or US export restrictions is essential to avoid customs delays. Samples are generally provided in 100 g to 500 g quantities, allowing laboratory evaluation of compatibility with the buyer’s polymer matrix.

Before placing a bulk order, confirm the supplier’s packaging integrity, such as inner‑liner material of drums and seal integrity, to prevent contamination. Ask for a recent third‑party analysis report (e.g., HPLC, GC‑MS) to validate purity claims of ≥ 98 %. Clarify the minimum order quantity, which for most listed chemicals is one 25 kg drum, and negotiate lead times that typically range from 15 to 30 days after order confirmation. Ensure that the commercial invoice clearly lists the HS code and CAS number to streamline customs clearance.
