Professional perspective: The know-how of importing X-ray diffractometers

As a senior consultant who has been deeply engaged inImport RepresentationA professional institution with 20 years of industry experience,ZhongShen International Traderecently successfully represented a batch of X-ray diffractometersImport Customs Declaration. Such precision instrumentsEquipment Importsoften involve complex HS code classification, technical parameter reviews, and other professional procedures. Based on our experience, approximately 35% of import delays stem from inadequate preliminary preparation. This article will analyze key nodes in the entire import process using real case studies.

Case study review: The customs clearance journey from Germany to Chengdu

The batch of X-ray diffractometers we recently represented came from a German manufacturer, with a value of approximately 120,000 euros. Several typical issues were encountered during the process:

• HS Code Disputes: Initially classified by the client as 9027.8090 (other physical and chemical analysis instruments), our professional team adjusted it to the more accurate 9022.1200 (X-ray diffractometers), reducing tariffs from 8% to 5%
• Lack of technical information: The technical parameter sheet provided by the German manufacturer lacked key radiation safety information. We assisted in supplementing CE certification and radiation safety test reports
• Port inspection: Chengdu Shuangliu Airport Customs conducted special testing on the instruments radiation indicators. Due to thorough preliminary documentation preparation, the process was completed in just 1.5 working days

Last year, a research institution importing the same equipment independently encountered these issues due to classification errors:
1. Overpaid taxes by 24,000 CNY
2. 9-day port detention due to incomplete technical documents incurred 12,000 CNY storage fees
3. Installation delays ultimately affected research progress
