Import Tips

Provide chemical analysis confirming 17-4 PH alloy (UNS S17400) to distinguish from standard stainless; pitfall is generic 'stainless' declaration triggering audits

Measure and declare precise tolerances; capillary tubing often scrutinized for 'tube' vs 'wire' classification

For cleanroom use, include surface finish specs (e.g

electropolished) in documentation
