Import Tips
• Document coating as <5% total weight to preserve steel classification; heavy coatings risk non-ferrous shift
• Test for magnetic permeability to distinguish from pure silicon hairsprings under Chapter 71
• Use material safety data sheets (MSDS) for coated products to address any hazmat concerns
