Penicillin G Amidase Enzyme Powder
Penicillin G amidase is a purified enzyme used in the biopharmaceutical industry to hydrolyze penicillin G into 6-aminopenicillanic acid (6-APA), a key intermediate for semi-synthetic antibiotics. This powder form is specifically classified under HTS 3507.90.20.00 as it matches the description of Penicillin G amidase, a prepared enzyme not elsewhere specified.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not specifically Penicillin G amidase
Other prepared enzymes not elsewhere specified fall under the residual subheading 3507.90.9000 if they don't match the precise description.
If prepared as a finished medicament
If formulated with excipients for direct therapeutic use as an antibiotic intermediate product, it shifts to Chapter 30 for medicaments.
If imported as part of a diagnostic reagent kit
Enzymes in lab diagnostic or research kits are classified under 3822 as composite lab reagents rather than pure enzymes.

Import Tips & Compliance
• Obtain a detailed Certificate of Analysis (CoA) verifying the enzyme's activity and purity to satisfy FDA and CBP requirements for biotech imports
• Declare as 'Penicillin G Amidase' explicitly on commercial invoices to avoid misclassification into general enzyme categories
• Ensure cold chain documentation for refrigerated shipments, as improper storage can degrade enzyme activity and lead to customs holds
