ABOUT THIS CODE

HTS 8504.40.9550, filed for CN-origin shipments under "Electrical transformers, static converters (for example, rectifiers) and inductors; parts…", sits in Chapter 85 (Electrical machinery and equipment and parts thereof; sound recorders and reproducers). The schedule reaches this line starting from heading 8504 — "Electrical transformers, static converters (for example, rectifiers) and inductors; parts thereof", narrowing to 8504.40 ("Static converters"). Level 1 — 8504: "Electrical transformers, static converters (for example, rectifiers) and inductors; parts thereof." Level 2 — 8504.40: "Static converters." Level 3 — 8504.40.95: "Other." Level 4 — 8504.40.95.50: "Other." Filed as: "Electrical transformers, static converters (for example, rectifiers) and inductors; parts…." Reading HTS 8504.40.9550's own digits: 8504 names the heading, 40 the subheading, and 9550 the statistical suffix — equivalently, digit positions 1 through 4 read 8504, positions 5 and 6 read 40, and the final four positions read 9550. USITC's Column 2 entry for HTS 8504.40.9550, applying to countries without normal trade relations status, reads "35%" — not the ordinary MFN rate a CN-origin shipment pays.
