About Chemtrade International - Chemical Supplier in China

Chemtrade International is based in China and currently lists five chemical products in its catalogue. The active product count of five includes Itaconic acid, Povidone‑iodine, Hydroxylamine hydrochloride, Nitromethane and Polyvinylpyrrolidone. These items belong to the industrial organic chemicals segment and are identified by their standard chemical names. The supplier is classified as an imported tier with a harbor trust tier, indicating it is sourced through established trade channels. The catalogue does not provide HS codes, but each chemical aligns with HS Chapter 29 for organic chemicals, a common classification for bulk chemical exports from China.

The listed chemicals serve distinct market functions: Itaconic acid is a monomer for specialty polymers, Povidone‑iodine is an antiseptic active in medical formulations, Hydroxylamine hydrochloride acts as a reducing agent in synthesis processes, Nitromethane is employed as a high‑energy solvent and fuel additive, and Polyvinylpyrrolidone is a water‑soluble polymer used as a binder and film‑former. Together they address demand in plastics manufacturing, pharmaceutical intermediates, agro‑chemical synthesis and specialty coating applications, reflecting a diversified product portfolio within a single supplier.

Product Range and Specialties of Chemtrade International

Chemtrade International’s catalogue comprises Itaconic acid, Povidone‑iodine, Hydroxylamine hydrochloride, Nitromethane and Polyvinylpyrrolidone. In the industry, Itaconic acid is typically supplied at a purity of 99 % or higher and conforms to ISO 9001 quality management; grades are often designated as technical‑grade (≈95 % purity) and high‑purity (≥99 %). Povidone‑iodine is commonly offered in aqueous solutions of 5 % to 10 % iodine concentration, with USP‑type specifications for pharmaceutical use. Hydroxylamine hydrochloride is shipped as a dry solid with moisture content below 0.5 % and is graded for analytical or industrial use. Nitromethane is usually provided with a water content under 0.1 % and a flash point of 35 °C, meeting ASTM D1150 standards for solvents. Polyvinylpyrrolidone (PVP) is available in various molecular weight ranges (K‑15 to K‑90) expressed in kilodaltons, with viscosity specifications (e.g., 10 cP to 1 M cP) that guide its use as a binder or film former.

Trade and Export Information - Chemtrade International

Exports of organic chemicals from China are concentrated in the Asia‑Pacific, European Union and North American markets, with HS Chapter 29 codes used for customs clearance. Buyers typically require proof of compliance with REACH (EU) or TSCA (US) regulations, as well as a Certificate of Analysis (CoA) for each batch. Commonly requested certifications include ISO 9001 for quality management and, where applicable, ISO 14001 for environmental management. Shipping of bulk chemicals from Chinese ports follows standard Incoterms such as FOB Shanghai or CIF Los Angeles; containers are usually 20‑ft or 40‑ft drums for liquids and bulk bags for solids, with UN packaging specifications applied to hazardous materials like Nitromethane. Chinese exporters often provide pre‑shipment inspection reports from agencies such as SGS or Bureau Veritas to satisfy importer due diligence.

The typical buyer profile for Chemtrade International’s product set includes polymer manufacturers seeking Itaconic acid monomer, pharmaceutical companies sourcing Povidone‑iodine or high‑purity Hydroxylamine hydrochloride, and specialty chemical firms requiring Nitromethane as a solvent. Importers generally request material safety data sheets (MSDS), third‑party test reports, and compliance declarations before contract signing. The Chinese chemical export environment emphasizes strict customs documentation, including accurate HS codes, weight declarations and proper labeling for hazardous substances.

Sourcing from Chemtrade International - Buyer Guidance

When sourcing from Chemtrade International, buyers should request a current Certificate of Analysis for each product to verify purity, moisture content and any specified impurity limits. For Itaconic acid and Polyvinylpyrrolidone, confirming the molecular weight distribution or polymer grade is essential; for Povidone‑iodine, the iodine concentration and USP‑type sterility status should be validated. Hydroxylamine hydrochloride and Nitromethone shipments should be accompanied by UN classification numbers and a full safety data sheet, as they are classified as hazardous under IMDG rules. Buyers are advised to verify that the supplier can provide REACH‑registration or equivalent regulatory documentation for EU or US markets, and to negotiate packaging options such as 20‑ft drums with inner liners for liquids or 25 kg bulk bags for solids to match logistical preferences.

What chemical products does Chemtrade International list for export?

The catalogue includes Itaconic acid, Povidone‑iodine, Hydroxylamine hydrochloride, Nitromethane and Polyvinylpyrrolidone, all classified under HS Chapter 29 for organic chemicals.

Which purity levels are typical for Itaconic acid from this supplier?

Industry practice is to offer technical‑grade at about 95 % purity and high‑purity grades at 99 % or higher, each supported by a Certificate of Analysis.

What documentation should a buyer request for Povidone‑iodine?

Buyers should request the USP‑type specification sheet, a Certificate of Analysis showing iodine concentration (5‑10 %), and an MSDS covering handling and storage.

Are there any special shipping requirements for Nitromethane?

Nitromethane is classified as a hazardous liquid (UN 1840) and must be packed in UN‑rated drums, labeled according to IMDG rules, and shipped under appropriate Incoterms such as FOB or CIF.

What certifications are commonly required for these chemicals?

Typical certifications include ISO 9001 quality management, REACH registration for EU markets, and a third‑party inspection report (e.g., SGS) confirming batch conformity.

What are the usual packaging formats for Hydroxylamine hydrochloride and Polyvinylpyrrolidone?

Hydroxylamine hydrochloride is often supplied in 25 kg bulk bags with moisture barriers, while Polyvinylpyrrolidone is shipped in 20‑ft drums or fiber drums, depending on grade and viscosity requirements.

Which regions import these types of chemicals most frequently?

Major import regions are the Asia‑Pacific (Japan, South Korea), the European Union (Germany, Netherlands) and North America (United States, Canada), where the chemicals are used in plastics, pharma and specialty applications.

What are typical lead times and minimum order quantities for these products?

Lead times generally range from 4 to 8 weeks after order confirmation, with minimum order quantities of 1 metric ton for bulk chemicals like Itaconic acid and 500 kg for specialty grades such as Povidone‑iodine.
