About Taizhou Diva Imp&exp Co., Ltd. - Laboratory Chemicals Supplier in China

Based in China, Taizhou Diva Imp&exp Co., Ltd. lists eight distinct laboratory chemical and reagent items in its online catalogue. The catalogue includes compounds such as Echinocandin B, 4-(4-bromopyrazol-1-yl)piperidine-1-carboxylic, and 4-(4-aminophenoxy)-N-methylpicolinamide, among others. All items fall under the broader categories of Laboratory Chemicals and Laboratory Reagents as defined by the supplier. The product entries are presented without accompanying HS codes, indicating that the supplier may rely on buyer‑provided classification during order processing. These eight entries represent the full active product count reported for the company.

The chemical names suggest a focus on specialized synthetic intermediates and bioactive molecules used in research and development. Such compounds are typically required in analytical or research grade purity for pharmaceutical, biotech, and academic laboratories. The supplier’s listing format aligns with standard chemical trade catalogues that reference molecular structures rather than bulk commodity grades. Potential buyers can expect the items to be supplied in laboratory‑grade packaging such as amber glass bottles or HDPE containers. The absence of additional product details implies that specifications and safety data sheets are provided on request.

Product Range and Specialties of Taizhou Diva Imp&exp Co., Ltd.

Taizhou Diva’s catalogue comprises eight individual chemical entities, each identified by its systematic name. The list includes antifungal agent Echinocandin B, halogenated heterocycles, and pyridine‑based amides, reflecting a portfolio of fine‑chemical intermediates. In the laboratory chemicals market, such compounds are typically offered in analytical grade (purity ≥ 98 %) or research grade (purity ≥ 95 %). Common specifications include documented melting point, NMR and MS spectra, and a Certificate of Analysis (CoA) confirming identity and purity. Buyers often request compliance with ISO 9001 quality management and, for pharmaceutical‑related intermediates, GMP‑compatible documentation.

Trade and Export Information - Taizhou Diva Imp&exp Co., Ltd.

Laboratory chemicals and reagents from China are classified under HS chapter 29 (organic chemicals). Export volumes from Chinese fine‑chemical hubs frequently target North America, Western Europe, and the Asia‑Pacific region, where pharmaceutical manufacturers, contract research organizations, and university laboratories import these goods. Typical import requirements include a full Material Safety Data Sheet (MSDS), a CoA, and, where applicable, certificates confirming compliance with REACH (EU) or TSCA (US). Shipping is commonly arranged on a CIF or FOB basis in 20‑ft or 40‑ft containers, with products packed in sealed, moisture‑controlled inner packs and outer cartons labeled with the appropriate HS code. Chinese exporters of fine chemicals often hold ISO 9001 and may seek additional certifications such as ISO 22716 for cosmetics‑related intermediates, though Taizhou Diva does not list specific certifications in its public data.

Sourcing from Taizhou Diva Imp&exp Co., Ltd. - Buyer Guidance

When sourcing from Taizhou Diva, buyers should request a current CoA and MSDS for each listed compound to verify purity, water content, and any residual solvents. It is advisable to confirm the intended grade (analytical vs research) and to ask for supporting analytical data such as HPLC or GC traces. Typical minimum order quantities for specialized intermediates range from 1 kg to 5 kg, but the exact MOQ should be clarified with the supplier. Packaging is usually in amber glass bottles (≤ 500 ml) or HDPE drums (≤ 25 kg), sealed with tamper‑evident caps and accompanied by a packing list that references the HS code. Lead times for custom‑synthesized molecules can extend from 2 to 6 weeks depending on synthesis complexity.

What types of products does Taizhou Diva list?

The supplier lists eight laboratory‑chemical items, including Echinocandin B, various bromopyrazole‑piperidine derivatives, chloropyrimidine‑based amines, and pyridine‑amide compounds, all classified under Laboratory Chemicals and Laboratory Reagents.

Are HS codes provided for the products?

The catalogue does not include HS codes; buyers typically assign the appropriate HS‑29 sub‑heading during the ordering process based on the chemical structure.

Which documents should a buyer request before purchase?

Buyers should ask for a Certificate of Analysis, a Material Safety Data Sheet, and any applicable regulatory compliance certificates such as REACH or TSCA declarations.

What purity levels are common for these chemicals?

In the fine‑chemical market, analytical grade purity is usually ≥ 98 % and research grade is ≥ 95 %; the supplier’s CoA will specify the exact purity for each batch.

What packaging formats are used for shipment?

Products are normally packed in sealed amber glass bottles or HDPE containers, placed in moisture‑controlled inner packs and boxed for transport in 20‑ft or 40‑ft containers.

Which markets typically import these types of laboratory reagents?

Major importers include pharmaceutical manufacturers, biotech firms, and academic research institutions in North America, Europe, and the Asia‑Pacific region.
