L-tryptophan
L‑tryptophan is an essential amino acid with the molecular formula C11H12N2O2, supplied by Inner Mongolia Fulifeng Trade Co., Ltd. The product is offered in bulk 25 kg bags, a standard packaging size for bulk chemical trade. The supplier describes the material as suitable for pharmaceutical, nutritional supplement and animal feed formulations. It is marketed as a pharmaceutical‑grade amino acid.
Typical pharmaceutical grades of L‑tryptophan achieve a purity of 99 % or higher, which aligns with industry expectations for human and veterinary use. Standard moisture content for bulk amino acids is below 0.5 % to preserve stability. The powder is usually milled to a particle size of around 200 mesh, facilitating uniform blending in formulations. Storage under dry conditions below 25 °C is standard practice to maintain potency.
Manufacturers of dietary supplements, pharmaceutical companies and animal‑feed producers commonly source this amino acid for serotonin and melatonin synthesis pathways. The supplier indicates flexible minimum order quantities and offers shipping terms such as FOB and CIF, allowing buyers to select the most suitable logistics arrangement. Buyers are advised to request the supplier’s ISO and FDA compliance documentation before finalising contracts. Payment methods typically include L/C or T/T, but exact terms should be confirmed directly with the supplier.

Sourcing L-tryptophan from Inner Mongolia Fulifeng Trade Co., Ltd. - China Import Guide
Before placing an order, importers should obtain the supplier’s ISO and FDA compliance certificates and a recent certificate of analysis for the specific batch of L‑tryptophan. Verifying the product’s purity, moisture content and HS code helps avoid customs delays and ensures the material meets pharmaceutical or feed standards.

The supplier mentions FOB and CIF shipping options, but the exact port of loading in China and the estimated lead time are not disclosed in the public data. Buyers need to confirm the preferred Incoterm, the loading port (e.g., Tianjin or Shanghai), and the expected transit duration to their destination. Payment methods such as letter of credit or telegraphic transfer should be agreed upon in the contract.
Upon arrival, a third‑party inspection should verify the batch’s assay result, moisture level and packaging integrity. Importers may request an on‑site laboratory test or review the supplier’s inspection report to ensure compliance with the agreed specifications. Proper documentation, including the commercial invoice, packing list and certificate of origin, must accompany the shipment for smooth customs clearance.
