For manufacturers of laser welding equipment, technical innovation and market competition may not be their biggest headache. Many enterprises receive US orders yet fail to deliver on schedule due to stalled FDA certification. FDA compliance is not merely a market access threshold; it is also a critical factor causing delivery delays, lost clients and regulatory compliance risks amid global business expansion.
