Mecasermin (Recombinant IGF-1)
Mecasermin (Recombinant IGF-1) is a recombinant insulin-like growth factor 1, a structural analogue closely related to the somatotropin/IGF-1 axis. Although it mediates the effects of somatotropin, it is a distinct polypeptide hormone with its own biological activity. It is used primarily for treating severe primary IGF-1 deficiency, and its classification under somatotropin is arguable due to its distinct structure and function.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as another polypeptide hormone rather than a somatotropin derivative
IGF-1 is a distinct polypeptide hormone and may fall under other polypeptide hormones.

Import Tips & Compliance
• Confirm the product's active ingredient and intended use with the manufacturer, as IGF-1 may be classified differently if used for non-hormonal purposes
• Provide a detailed product monograph to the CBSA to support classification as a polypeptide hormone
• Check if a Drug Identification Number (DIN) or Notice of Compliance is required for importation into Canada

Human Growth Hormone Reference Standard USP
Human Growth Hormone Reference Standard USP is a highly purified recombinant somatotropin preparation used exclusively for quality control, assay calibration, and standardization in pharmaceutical manufacturing. It meets United States Pharmacopeia specifications for identity, purity, and potency, and is imported in small quantities for laboratory use. As a chemically defined polypeptide hormone, it falls squarely under tariff item 2937.11.00.
Pegylated Somatotropin (PEG-GH)
Pegylated Somatotropin (PEG-GH) is human somatotropin conjugated with polyethylene glycol (PEG) to extend its half-life and reduce injection frequency. This structural modification creates a derivative of somatotropin used primarily for its hormonal effect in growth hormone therapy. The PEGylation does not alter the core hormonal function, making it classifiable under somatotropin derivatives.
Recombinant Human Growth Hormone (Somatropin)
Recombinant Human Growth Hormone (Somatropin) is a recombinant DNA-derived version of human somatotropin, identical in structure to the natural pituitary hormone. It is used primarily to treat growth hormone deficiency in children and adults. As a chemically defined polypeptide hormone, it is directly classifiable under tariff item 2937.11.00.
Somatotropin Lyophilized Powder for Injection
Somatotropin Lyophilized Powder for Injection is a freeze-dried form of recombinant human somatotropin for reconstitution prior to injection. It is used in growth hormone replacement therapy and maintains the structural integrity of the polypeptide hormone. The lyophilized presentation does not change the product's classification under somatotropin.
Somatrem (Methionyl Human Growth Hormone)
Somatrem (Methionyl Human Growth Hormone) is a structurally modified form of human somatotropin with an extra methionine residue at the N-terminus. This modification makes it a derivative of somatotropin used for growth hormone replacement therapy. The analogue maintains the biological activity of the natural hormone and is classifiable under somatotropin derivatives.
Somatrogon (Long-Acting Growth Hormone)
Somatrogon (Long-Acting Growth Hormone) is a structural analogue of somatotropin created by linking human growth hormone to a CTP (C-terminal peptide) sequence from the hCG beta subunit. This modification extends its half-life for weekly dosing. As a structural analogue used primarily for its hormonal effect, it is classifiable under somatotropin derivatives.
