Quality control is an integral part of API production. Regulatory agencies, such as the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA), impose stringent guidelines to ensure that APIs meet established standards. Compliance with Good Manufacturing Practices (GMP) is mandatory to maintain the quality and consistency of APIs. Furthermore, the analytical techniques employed, such as chromatography and spectroscopy, play a vital role in verifying the identity, strength, and purity of the APIs.

Heavy duty machines typically have higher maximum sewing speeds, around 1500 stitches per minute, versus 1000-1200 stitches per minute for standard machines. Again, this allows them to work through heavy fabrics more efficiently. However, heavy duty machines also tend to sew better at slower speeds, in the 500-800 stitch per minute range, for optimal control through thick seams. So they provide a wider speed range to suit the fabric.
