Not a typo — a classification gap. In China Customs, Chapter 84 (machinery) and Chapter 85 (electrical machinery/equipment) sit right next to each other, but the duty difference between them can wipe out an entire shipment margin. The catch? Many industrial products do both mechanical work and electrical control.

China Customs applies the “principal function” rule. If the device is mainly mechanical — motors, conveyors, processing machines — it tends to land in Chapter 84. If its core value is electrical control, conversion, or regulation — power units, control cabinets, automation controllers — Chapter 85 is more likely. Borderline cases are decided case by case, and audits can look back more than a year after the original entry.

The real risk isn’t the rate itself. It’s the retroactive duty recovery, administrative fine, and compliance record that follow a wrong call. We see this most often on industrial equipment, auto parts with embedded electronics, and automated production modules imported into China.

Our take: get the HS code locked before the PO, not after the audit. An advance classification ruling is the cheapest insurance against a 5-figure invoice shock.

Comment ‘guide’ if you’re importing machinery or electrical equipment into China.
