About Weifang Kaihong Chemical Ltd. - Industrial Chemicals Supplier in China

Weifang Kaihong Chemical Ltd. is based in China and currently lists five distinct chemical products. The company’s catalogue focuses on brominated flame retardants within the industrial chemicals sector. Products include Tetrabromobisphenol A, Tetrabromobisphenol A bis (2, 3‑dibromopropyl ether), Hexabromocyclododecane (HBCD), an HBCD masterbatch, and Decabromodiphenyl ethane (DBDPE). Each item falls under the broader classification of industrial chemicals used for fire‑safety applications. The supplier is recorded as an imported tier with a harbor trust tier, indicating active cross‑border trade.

The five listed items are all organic brominated compounds that function as flame‑retardant additives for polymers, textiles, and foams. In trade data, such compounds are generally classified under HS Chapter 29 for organic chemicals or Chapter 38 for other chemical products. Buyers typically encounter these chemicals in powder or masterbatch form, with specifications that include purity percentages, moisture limits, and particle size distribution. The catalogue does not provide individual HS codes, so trade classifications rely on the standard headings for brominated flame retardants.

Product Range and Specialties of Weifang Kaihong Chemical Ltd.

The catalogue comprises Tetrabromobisphenol A, a high‑purity (≥99 %) phenolic flame retardant commonly supplied as a fine powder. Industry practice also offers a bis(2,3‑dibromopropyl ether) derivative, which is used where higher thermal stability is required. Hexabromocyclododecane (HBCD) appears both as a bulk chemical and as a masterbatch, the latter being pre‑mixed with a polymer carrier at typical loadings of 10‑30 % by weight. Decabromodiphenyl ethane (DBDPE) is another high‑performance brominated flame retardant, usually supplied in granular form with particle sizes of 0.5‑2 mm. Across these products, standard quality grades reference ISO‑based purity tests, moisture content below 0.5 %, and compliance with RoHS limits for restricted substances.

Trade and Export Information - Weifang Kaihong Chemical Ltd.

China is a leading exporter of brominated flame retardants, and shipments from the country are directed mainly to the European Union, North America, and Southeast Asian manufacturing hubs. Export filings for these chemicals typically use HS headings 2925.90 (other organic chemicals) or 3824.90 (chemical products not elsewhere specified). Importing parties often require REACH registration in the EU, TSCA compliance in the United States, and ISO 9001 quality management certification from the supplier. Standard packaging includes multi‑layered polyethylene bags or 25 kg IBC drums, with moisture‑barrier liners for bulk shipments. Common Incoterms are FOB Shanghai or CIF destination ports, and freight is usually arranged in 20‑ft or 40‑ft containers depending on volume.

Sourcing from Weifang Kaihong Chemical Ltd. - Buyer Guidance

When sourcing from this supplier, buyers should request a current Material Safety Data Sheet (MSDS) and a Certificate of Analysis (CoA) that details purity, moisture, and particle size for each product. Confirmation of REACH registration or an equivalent chemical regulatory status is advisable for EU shipments, while US buyers should verify TSCA compliance. Sampling is typically offered in 500 g to 1 kg quantities; buyers should assess the sample against the required flame‑retardancy performance standards such as UL 94 V‑0 or V‑1 before confirming larger orders.
