Three Hidden Pitfalls in Customs Clearance for Imported Wire-Cut EDM Machines

PrecisionThe compliance threshold is being raised.

The latest amendment to the "Measures for the Import Management of Electromechanical Products" in 2025 sets stricter entry requirements for precision processing equipment.Taking wire EDM equipment as an example,the focus of customs inspection has shifted from simply declaring the price to other aspects.Technical Parameter VerificationwithUse-Case Review.In a recent import case involving a German-brand machine,we found that the same model can be assigned HS codes ranging from 8456.30 to 8456.90 depending on its machining accuracy,resulting in a 5.8 % difference in import duty.

Analysis of Typical Risk Cases

When a certain company imported Japanese low-speed wire-cut EDM equipment,it failed to distinguishBasic ConfigurationwithOptional Module,resulting in the CIF price being re-assessed by customs at 128% of the declared value.A professional agent,by providing the manufacturerModular Pricing List,successfully reducing the additional tax from 370,000 yuan to 85,000 yuan.This case reveals: the ability to declare equipment disassembly directly affects import-cost control.
