About Chengdu Youngshe Chem Co., Ltd - Cosmetic Chemicals Supplier in China

China‑based Chengdu Youngshe Chem Co., Ltd lists 103 active cosmetic‑chemical products in its online catalogue. The items are grouped under peptide‑based actives such as dipeptides, tripeptides, tetrapeptides and a pentapeptide, each identified with an HS‑code in the 2930‑2939 range or, for a single entry, 3304.99. Examples include L‑Carnosine (HS 2939.80), Dipeptide‑2 (HS 2937.29) and Tripeptide‑1 (HS 2934.90). The catalogue also records molecular formulas and typical assay purities, for instance Palmitoyl Tripeptide‑1 (C30H54N6O5, ~578.8 g mol‑1) and Acetyl Tetrapeptide‑33 (C20H32N8O6, ~480 g mol‑1).

The product list spans more than 30 distinct peptide families, each supplied as a synthetic cosmetic grade powder or liquid. Several entries note purity levels of 95 % or higher, and a few specify “cosmetic grade” or “synthetic” in the material description. HS codes such as 2937.29 (organic compounds, other) and 2932.99 (other organic chemicals) indicate that the goods fall under Chapter 29 of the Harmonised System, which covers organic chemicals used in personal‑care formulations.

Product Range and Specialties of Chengdu Youngshe Chem Co., Ltd

The catalogue concentrates on short‑chain peptides that are widely used as active ingredients in anti‑aging, skin‑brightening and hair‑care formulations. Typical industry specifications for such actives require a minimum of 95 % purity, verification by HPLC or LC‑MS, and a documented peptide sequence. Buyers often look for molecular‑weight data (most of the listed peptides range from 300 g mol‑1 to 600 g mol‑1) and stability information under neutral pH. In practice, these peptides are supplied in 25 g amber vials, 100 g bulk bags, or 1 kg drums, with moisture content below 2 % to preserve activity.

Chinese peptide manufacturers commonly meet ISO 9001 quality‑management standards and, for cosmetic applications, ISO 22716 (GMP for cosmetics). Export‑ready batches are usually packed in sealed polyethylene bags with a desiccant, labeled with batch number, expiry date and assay result, which aligns with the requirements of major importing regions.

Trade and Export Information - Chengdu Youngshe Chem Co., Ltd

China is a leading exporter of cosmetic active ingredients, and peptide actives fall under HS Chapter 29 (organic chemicals). Major import markets include the United States, the European Union (especially Germany, France and Italy), Japan and South Korea, where formulators seek high‑purity peptides for premium skin‑care lines. Buyers typically request certificates such as ISO 9001, ISO 22716, GMP compliance, and, where applicable, FDA Cosmetic Ingredient Review (CIR) or EU Cosmetic Regulation (EC 1223/2009) documentation. Standard Incoterms for these shipments are FOB Shanghai or CIF Hong Kong, with 20‑ft containers capable of holding roughly 10 - 12 tonnes of powdered peptide material, depending on packaging density.

The Chinese regulatory environment mandates that exported cosmetic chemicals comply with the “Regulations on the Administration of Cosmetic Products” and, when destined for the EU, meet the REACH registration requirements for substances above 1 tonne per year. Inspection agencies such as SGS or Bureau Veritas frequently perform pre‑shipment sampling to verify purity and microbial limits, which are standard expectations for high‑value peptide exports.

Sourcing from Chengdu Youngshe Chem Co., Ltd - Buyer Guidance

When sourcing from Chengdu Youngshe Chem, request a full Certificate of Analysis (CoA) for each peptide batch, including assay percentage, HPLC chromatogram, and mass‑spectrometry confirmation of the molecular weight. Verify that the supplier can provide GMP or ISO 22716 certification, and ask for stability data at the intended storage temperature (typically 2‑8 °C for peptide powders). It is also prudent to obtain a sample of at least 5 g for in‑house testing before confirming a larger order, and to confirm that the packaging meets moisture‑barrier specifications (≤2 % moisture).

Confirm that the HS code listed in the purchase order matches the product’s chemical classification, and request the supplier’s export documentation package (commercial invoice, packing list, certificate of origin) in advance. Checking the batch number against the CoA and ensuring that the purity meets the ≥95 % threshold will reduce the risk of formulation failures.

What types of peptide actives does Chengdu Youngshe Chem list?

The supplier lists dipeptides, tripeptides, tetrapeptides and a pentapeptide, all described as synthetic cosmetic‑grade compounds with HS codes in the 2930‑2939 range.

Which HS codes are associated with the listed peptides?

Typical HS codes include 2939.80 for L‑Carnosine, 2937.29 for many di‑ and tri‑peptides, 2934.90 for Tripeptide‑1, 2932.99 for Trifluoroacetyl Tripeptide‑2, 2933.59 for Palmitoyl Tetrapeptide‑10 and 3304.99 for Tetrapeptide‑16.

What purity levels are indicated for the peptides?

Several catalogue entries specify purity of 95 % or higher; other entries are described simply as “cosmetic grade,” which in the industry generally implies ≥95 % purity verified by HPLC.

Which certifications should a buyer request from this supplier?

Buyers should request ISO 9001, ISO 22716 (cosmetic GMP) and any GMP certificates the supplier holds; these are the typical certifications required for cosmetic peptide imports.

What documentation is needed before placing an order?

A Certificate of Analysis, batch‑specific CoA, GMP/ISO certificates, and standard export paperwork (commercial invoice, packing list, certificate of origin) are standard documents.

What are the common packaging formats for these peptides?

Industry practice is to ship peptide powders in sealed polyethylene bags with desiccant, placed in 25 g amber vials, 100 g bulk bags or 1 kg drums, all labeled with batch and expiry information.

Which markets commonly import Chinese cosmetic peptides?

The United States, the European Union (especially Germany, France and Italy), Japan and South Korea are the primary import markets for Chinese cosmetic peptide actives.

What are typical lead times and minimum order quantities?

Lead times for synthetic peptides from Chinese manufacturers usually range from 30 to 60 days, and minimum order quantities are often 5 g for sample testing and 1 kg for commercial shipments, depending on the specific peptide.
