Puyang Henvan Trading Co., Ltd. — Verified Supplier
About Puyang Henvan Trading Co., Ltd. - Sodium Percarbonate Supplier in China
China‑based Puyang Henvan Trading Co., Ltd. lists five active chemical products in its catalogue. The items include Sodium percarbonate, Thiourea dioxide, Furfuryl alcohol, a pulp bleaching agent (referred to as “fas”), and Furfural. Each product falls under the broader inorganic or organic chemical categories used in bleaching, reducing, and resin‑forming applications. The supplier’s catalogue does not provide HS codes, so buyers should verify the appropriate HS chapters (e.g., 28 for inorganic chemicals, 29 for organic aldehydes) during customs clearance.
The Sodium percarbonate offered is an oxygen‑releasing bleaching agent, while Thiourea dioxide is a strong reducing agent commonly used in textile processing. Furfuryl alcohol serves as a key intermediate for resin and polymer production, and Furfural is an aldehyde derived from biomass, used in solvents and flavoring intermediates. The pulp bleaching agent “fas” is marketed for paper‑pulp brightness improvement. All five products are listed without specific purity claims in the supplier data, so buyers need to request detailed assay reports.
Product Range and Specialties of Puyang Henvan Trading Co., Ltd.
The catalogue lists Sodium percarbonate, Thiourea dioxide, Furfuryl alcohol, a pulp bleaching agent (fas) and Furfural. In the chemical trade, Sodium percarbonate is typically supplied in grades with 45 % - 55 % active oxygen, particle sizes of 200 - 500 µm, and purity of 95 % - 99 % by weight. Thiourea dioxide grades usually reach 98 % purity and are shipped in 25 kg or 50 kg bags for textile bleaching. Furfuryl alcohol is commonly offered at ≥99 % purity, with moisture content below 0.5 % and packaged in 20 L drums or 25 kg bags. Furfural grades for industrial use are generally ≥99 % purity, low aldehyde content, and shipped in 25 kg bags or 200 L drums. The pulp bleaching agent “fas” is often a sodium percarbonate‑based formulation, supplied in 25 kg bags with standard moisture limits of ≤5 %. Buyers should request a Certificate of Analysis (CoA) and Safety Data Sheet (SDS) for each product to confirm these typical specifications.
Trade and Export Information - Puyang Henvan Trading Co., Ltd.
China is a leading exporter of inorganic peroxides and organic aldehydes, with Europe, North America and Southeast Asia representing the largest import markets. Sodium percarbonate falls under HS Chapter 28 (e.g., 2836.30), while Thiourea dioxide, Furfuryl alcohol and Furfural are classified under HS Chapter 29 (e.g., 2933.39 for furfural). Export shipments are usually packed in 25 kg or 50 kg polypropylene bags, placed in 20‑ft or 40‑ft containers, and shipped under FOB or CIF terms. Buyers typically request REACH registration, GHS classification, and an ISO‑9001 quality management statement from Chinese chemical exporters, even when the supplier does not explicitly hold these certifications. Customs inspections often focus on correct HS code declaration, proper labeling of hazardous substances, and compliance with the Globally Harmonized System for classification and labeling of chemicals.
