Somatrogon (Long-Acting Growth Hormone) from Japan

Somatrogon is a long-acting structural analogue of somatotropin created by linking human growth hormone to a CTP (C-terminal peptide) sequence from hCG beta subunit. This modification extends its half-life for weekly dosing in growth hormone deficiency. Classified in HTS 2937.11.00.00 as a chain-modified polypeptide analogue used primarily as a hormone.

Import Tips

Submit sequence analysis confirming CTP modification for chain-modified polypeptide classification

Maintain validated cold chain (2-8°C) with temperature monitoring records

Avoid bulk packaging declarations that might suggest non-hormonal protein status
