About Shandong Angel Chemical Co., Ltd. - Chemicals & Allied Products Supplier in China

China‑based Shandong Angel Chemical Co., Ltd. lists 33 active chemical products across the catalogue. The list includes Bronopol, 1,2,5,6,9,10‑Hexabromocyclododecane (HS 2903.39) and 2‑Cyanoacetamide (HS 2924.19) among other brominated and nitrogen‑based intermediates. Several entries carry specific HS codes such as DBNE (HS 2905.49), TBBA/TBBPA (HS 3824.83) and OIT‑99 (HS 3808.92), indicating coverage of HS chapters 28, 29, 38 and 39. The catalogue also mentions polymer additives like Brominated SBS (HS 3824.99) and Brominated Polystyrene (HS 3903.90).

China also provides a set of water‑treatment chemicals, for example Sodium Dichloroisocyanurate Dihydrate (HS 2933.61) with minimum 55 % effective chlorine, Calcium Hypochlorite (HS 2828.10) at 65‑70 % active chlorine, Polyaluminium Chloride and Aluminum Chloride (HS 2827.32). Additional inorganic salts such as Sodium Bromate (HS 2829.00) and Ammonium Sulfate (HS 3102.30) are listed. The presence of multiple HS‑code families (2827‑2830, 2903‑2934, 3808‑3824, 3903) shows the supplier’s activity across both organic intermediates and inorganic water‑treatment agents. The catalogue does not provide any manufacturing capacity or certification details.

Product Range and Specialties of Shandong Angel Chemical Co., Ltd.

The catalogue covers brominated flame retardants (HBCD, DBDE, TBBA/TBBPA), isothiazolinone biocides (OIT‑99, OIT‑45, DCOIT‑99, BIT‑85) and halogenated hydantoin disinfectants (DBDMH, DCDMH, DCDIH). In the industry, HBCD is typically supplied in technical grade at 99 % purity for polymer extrusion, while TBBPA grades range from 97 % to 99 % bromine content for electronic housing applications. Isothiazolinones are commonly sold as 99 % active concentrates for preservative formulations, with standard test methods including HPLC for active content. Water‑treatment chemicals such as Sodium Dichloroisocyanurate are usually shipped in 25 kg drums with chlorine residual verified by iodometric titration, and Calcium Hypochlorite is offered in granular or powder form meeting ASTM C‑1028 specifications.

Trade and Export Information - Shandong Angel Chemical Co., Ltd.

Chinese chemical exporters of brominated compounds, biocides and water‑treatment agents typically ship to Southeast Asia, Europe and North America. HS chapters 28‑29 cover inorganic salts and halogenated organics, while chapters 38‑39 address polymer additives; customs authorities often request REACH registration certificates for EU imports and MSDS for all hazardous chemicals. Common certifications requested by buyers include ISO 9001 quality management, REACH compliance for brominated substances, and OECD‑TG for ecotoxicity. Standard packaging consists of 25 kg steel drums, 20 ft or 40 ft containers, and bulk bags for inorganic salts, with Incoterms FOB or CIF frequently used. Export control in China requires declaration of hazardous waste under the Basel Convention for certain brominated products, and customs may inspect for correct HS coding and safety documentation.

Sourcing from Shandong Angel Chemical Co., Ltd. - Buyer Guidance

Buyers should request a latest batch analysis report showing purity, bromine content or active chlorine percentage, together with a full Safety Data Sheet and, where applicable, REACH registration evidence. For biocides such as OIT or BIT, a microbiological efficacy test report (e.g., ASTM E‑214) helps verify performance. Verify that the HS code on the commercial invoice matches the product material to avoid customs delays, and confirm packaging dimensions to plan container loading. Request a certificate of analysis for each shipment and, for water‑treatment chemicals, a chlorine residual test result performed by an accredited laboratory before loading.

What documentation is required before ordering chemicals from Shandong Angel Chemical Co., Ltd.?
