When sourcing lures, prioritize high-impact ABS plastic for hard baits to ensure durability against rocks and predatory teeth. For soft lures, verify the use of eco-friendly PVC or silicone that is phthalate-free to meet international environmental standards. Pay close attention to the internal weight transfer system (such as tungsten balls), which is critical for casting distance and underwater balance. Ensure that all hardware, specifically split rings and treble hooks, are made of 304 or 316 stainless steel or have a corrosion-resistant coating (like black nickel) to prevent rusting in saltwater environments.
