About Jostrong (Tianjin) Technology - Industrial Chemicals Supplier in China

Jostrong (Tianjin) Technology operates out of Tianjin, China and currently lists seven active chemical products. The catalogue focuses on niche organic intermediates used in pharmaceutical synthesis, agro‑chemical research and specialty material development, all falling under the Industrial Chemicals and Chemicals & Allied Products categories.

The supplier’s product list includes Ethyl Trifluoro Acetoacetate, Thio Acetamide, 2,6‑Dibromo‑4‑(Trifluoromethoxy) Aniline, 2‑Hydroxy‑6‑(Trifluoromethyl) Pyridine, 5‑Thiazolecarboxylic acid (CAS 117724‑63‑7), 6‑Ethyl‑5‑Fluoro‑4‑Hydroxy Pyrimidine and 4‑Chloro‑6‑Ethyl‑5‑Fluoro Pyrimidine. Each entry is identified by its chemical name and conforms to the standard nomenclature used in the global chemical trade.

Product Range and Specialties of Jostrong (Tianjin) Technology

The seven items are all organic heterocyclic or fluorinated intermediates that are typically supplied in bulk quantities ranging from 25 kg drums to 1 ton IBC containers. In the chemical industry, buyers usually require a minimum purity of 98 % for research‑grade material and 99 % or higher for pharmaceutical‑grade intermediates, with moisture content below 0.5 %. Common analytical specifications include HPLC purity, NMR confirmation and gas chromatography for residual solvents.

Industry practice for these classes of compounds also involves standard safety data sheets (SDS) prepared according to the Globally Harmonized System (GHS) and, where applicable, compliance with REACH registration for the European market. Typical grades are described as “research grade”, “pharma‑intermediate grade” or “high‑purity grade”, each with defined limits on metal impurities and halogen content.

Trade and Export Information - Jostrong (Tianjin) Technology

Exporters of specialty organic intermediates from China normally classify these products under HS Chapter 29 (Organic Chemicals), with sub‑headings such as 2933 for heterocyclic compounds and 2935 for fluorinated organic chemicals. Major import regions include North America, the European Union and Southeast Asia, where pharmaceutical manufacturers and agro‑chemical firms source bulk intermediates.

Buyers frequently request certificates such as ISO 9001 quality management, REACH compliance statements, and third‑party analysis reports (e.g., SGS, Eurofins). Packaging is usually in sealed metal drums or IBCs with inner liners of HDPE, and shipments are commonly arranged on 20 ft or 40 ft containers under CFR or CIF Incoterms. Chinese exporters also follow customs requirements for hazardous materials, providing UN numbers and proper labeling.

Sourcing from Jostrong (Tianjin) Technology - Buyer Guidance

When sourcing from Jostrong (Tianjin) Technology, buyers should request a recent Certificate of Analysis (COA) that details purity, water content and residual solvent levels for each batch. A complete Safety Data Sheet (SDS) and, if the destination is the EU, a REACH registration dossier or equivalence statement are standard prerequisites.

It is advisable to verify the supplier’s ISO 9001 certification and to obtain a third‑party laboratory test report before confirming a large order. Buyers should also confirm packaging material, drum linings and the presence of any hazardous material markings to ensure compliance with both export and import regulations.
