MSG is generally recognized as safe (GRAS) under FDA regulations, but imported food-grade MSG must comply with FDA labeling and purity standards. Shipments may be subject to FDA examination at the port of entry, and importers should ensure the product is accompanied by a certificate of analysis confirming food-grade specifications. Consulting a licensed customs broker or FDA-registered agent is advisable for first-time importers.
MSG's distinct commercial identity as a high-volume food ingredient, combined with its separate trade statistics significance, led to its own 10-digit line (2922421000).
