China hosts Chengdu Alpha Biotech Co., Ltd., a supplier that currently lists six active chemical products. The catalogue spans the Agriculture and Cosmetic Raw Material categories. Products include Potassium 4‑Methoxysalicylate, Rhododendrol, Deoxyarbutin, Bis(5‑Oxo‑L‑Prolinato‑N1,O2) Zinc, Linagliptin, and Hydroquinone Dipropionate. Deoxyarbutin is the only item with a disclosed HS code (2932.13) and a defined molecular formula C11H14O3. All items are described by their chemical names without additional packaging or concentration data.

The listed chemicals are typical intermediates or active ingredients used in crop‑protection formulations and skin‑care or whitening products. Potassium 4‑Methoxysalicylate functions as a plant growth regulator, while Rhododendrol and Hydroquinone Dipropionate are common skin‑lightening agents. Bis(5‑Oxo‑L‑Prolinato‑N1,O2) Zinc is a zinc chelate employed in cosmetic stabilization. Linagliptin is a pharmaceutical intermediate that can also appear in research‑grade supplies. The supplier’s catalogue does not specify purity levels, but the chemicals fall under HS chapter 29 organic chemicals.

Product Range and Specialties of Chengdu Alpha Biotech Co., Ltd.

The catalogue comprises six distinct organic chemicals: Potassium 4‑Methoxysalicylate, Rhododendrol, Deoxyarbutin (HS 2932.13), Bis(5‑Oxo‑L‑Prolinato‑N1,O2) Zinc, Linagliptin, and Hydroquinone Dipropionate. In the cosmetic raw‑material market, these compounds are typically supplied at purity grades of 98 % - 99.5 % for skin‑care applications, with water content limited to 0.5 % or less and heavy‑metal limits below 10 ppm. Agricultural chemicals such as the growth regulator are usually formulated to meet ISO 14001 environmental standards and may be blended to specific active‑ingredient percentages. Typical export packaging includes 25 kg steel drums, 200 L intermediate bulk containers, and smaller amber glass bottles for high‑purity grades. Bulk shipments are sealed with tamper‑evident liners, and safety data sheets accompany each batch to satisfy importer requirements.

Trade and Export Information - Chengdu Alpha Biotech Co., Ltd.

Chinese exporters of organic intermediates commonly ship to the European Union, North America, Japan, and Southeast Asian markets. The HS code 2932.13 for Deoxyarbutin belongs to the aromatic hydroxy compounds chapter, which often triggers REACH registration checks in the EU and TSCA review in the United States. Buyers usually request ISO 9001 or GMP‑type quality management documentation, as well as a Certificate of Analysis and Material Safety Data Sheet for each batch. Logistics for these chemicals typically involve 20‑ft or 40‑ft containers, with freight terms such as CIF or FOB prevailing. Export controls in China require customs declarations that match the HS code and material description, and customs inspections may verify compliance with hazardous‑material regulations (e.g., IMDG for drum shipments).

Sourcing from Chengdu Alpha Biotech Co., Ltd. - Buyer Guidance

When sourcing from this supplier, request a current Certificate of Analysis that details purity, assay method (HPLC or GC), water content, and heavy‑metal limits. Obtain the latest Material Safety Data Sheet and confirm whether the product complies with ISO 9001, GMP, or REACH requirements relevant to the intended market. Verify packaging specifications - drum size, liner material, and any moisture barrier - to ensure product stability during transit. Before confirming a large order, ask for a small sample (1 kg or 500 g) to run independent laboratory verification, and clarify the supplier’s lead time, which is usually 4 - 6 weeks for first‑time production. Confirm the declared HS code (e.g., 2932.13 for Deoxyarbutin) matches the customs invoice, and discuss Incoterms (FOB Chengdu or CIF destination port) to align responsibilities for freight and insurance.

What HS code should be used for customs when importing Deoxyarbutin from China?

The standard HS code for Deoxyarbutin is 2932.13, classified under aromatic hydroxy compounds. Buyers should verify that the commercial invoice lists this code to avoid customs delays.

Which certificates are typically required for cosmetic raw materials from China?
