Rui Heng Technology & Trade Co., Ltd. operates from China and currently lists five distinct chemical products in its catalogue. The active product count of five includes 2-(Phenylsulfonyl)aniline, Dexrazoxane, Tosylmethyl isocyanide, Procainamide hydrochloride, and 1,2-Diaminopropane-N. Three of these items are associated with specific HS codes: Tosylmethyl isocyanide (HS 2929.90), Procainamide hydrochloride (HS 2933.59) and 1,2-Diaminopropane-N (HS 2921.29). The remaining two chemicals are listed without HS-code data in the source information. All products fall under the broader Customs tariff chapter 29 for organic chemicals.
The catalogue covers a small set of specialty organics that are common intermediates or active pharmaceutical ingredients. Tosylmethyl isocyanide is typically supplied with a purity of 98‑99 % and a moisture content below 0.1 %, while Procainamide hydrochloride as an API is usually required at ≥99 % assay and complies with pharmacopeial specifications such as USP or EP. 1,2-Diaminopropane-N, classified as an aliphatic diamine, is often shipped with a nitrogen content of 99 % and low heavy‑metal residues. Dexrazoxane and 2-(Phenylsulfonyl)aniline are also handled as high‑purity intermediates, generally meeting ISO‑9001 quality management standards and providing a Certificate of Analysis for each batch. Buyers in fine‑chemical and pharmaceutical sectors frequently request specifications on residual solvents, heavy metals (≤10 ppm) and particle size distribution where relevant.
The catalogue provides HS 2929.90 for Tosylmethyl isocyanide, HS 2933.59 for Procainamide hydrochloride and HS 2921.29 for 1,2-Diaminopropane-N. The other two products fall under the broader chapter 29 for organic chemicals but no specific HS code is listed.
Buyers should ask for a Certificate of Analysis, a Material Safety Data Sheet, and any available ISO‑9001 or GMP certificates. For pharmaceutical APIs, a batch‑specific pharmacopeial compliance statement (USP/EP) is also advisable.
Procainamide hydrochloride is usually supplied at ≥99 % assay. Intermediates such as Tosylmethyl isocyanide and 1,2-Diaminopropane-N are commonly offered at 98‑99 % purity with moisture below 0.1 %.
Standard export packaging includes 25 kg IBC drums or 200 kg steel drums with inner liners. Small sample quantities may be shipped in sealed glass vials or polyethylene bottles.
Suppliers in China frequently quote FOB Shanghai or CIF Rotterdam for fine‑chemical shipments, depending on the buyer’s preferred logistics arrangement.
