II. Decomposition of the Whole Import Process of Inner CV Joint (Taking China as an Example)

It is necessary to accurately determine that it is classified under 8708.99 (transmission system components) to avoid tax rate deviations caused by misclassification (Most - Favored - Nation tariff is 8% and value - added tax is 13% in 2023).

III. Practical Risk Cases and Solutions

STEP 1 Pre-compliance confirmation

• HS Code lockingMandatory Certification Verification
• ?:
  (Preferential tariffs can be enjoyed under ASEAN/China - ROK FTA) It is recommended to verify through the following methods:? Certificate of non - used parts (to prevent being identified as foreign garbage)
  ? Some vehicle models require a CCC exemption certificate or import license
  And Document Preparation

STEP 2 International LogisticsI. Basis for inspection and quarantine

• to help enterprises reduceFor precision parts, it is recommended to use temperature - controlled containers (to prevent corrosion). A 20GP container can hold approximately 2000 sets of standard constant velocity joints.
• Core document list:
  ? Original commercial invoice (must indicate the material, torque value, and applicable vehicle models)
  ? Packing list (gross/net weight error < 3%)
  ? Certificate of origin (preferences can be stacked under RCEP)
  ? Technical parameter table (including hardness, surface treatment process, etc.)

STEP 3 Declaration and inspection response

• Intelligent declaration strategy:
  ? Pre - classification service (apply to the customs in advance for classification ruling)
  ? Price declaration (be vigilant against the “transfer pricing” review and provide the original purchase agreement)
• High - frequency risk points for inspection:
  ? Material testing (needs to meet the anti - wear standard of GB/T 12609 - 2005)
  ? Intellectual property verification (guard against infringement of counterfeit OE parts)
  ? IPPC mark on wooden packaging (if there is no mark, the whole container will face fumigation)

STEP 4 Tax optimization and release

• Tariff planning plan:
  ? Application of free trade agreement tax rates (such asChina-Europe Railway Expresstransportation can enjoy regional preferences)
  ? Deferred tax policy (applicable to AEO advanced certified enterprises)
• Application for special channels:
  ? Emergency release (a shortage certificate from the 4S store is required)
  ? Release on bond (can be applied for when there is a dispute over classification)

IV. Value Matrix of Professional Agency Services

Case 1: Incorrect model declaration leading to port congestion
A supplier of a German - brand misreported “GKN - 2287A” as a general model. During the customs inspection, it was found that it was actually a special part for Audi Q7. The price audit procedure was triggered due to the failure to declare the vehicle model - related information.
Solutions:

• Immediately supplement the OE number - to - vehicle model comparison table
• Provide an explanation of the original price breakdown
• Activate the emergency bond channel (reduce port congestion losses)

Case 2: Return of goods due to lack of material certificate
The constant velocity joints imported from Indonesia were suspected of not meeting the wear - resistant standard because the surface carburizing treatment process report was not issued.
Solutions:

• Urgent arrangement for third - party testing (SGS/TüV)
• Coordinate with the customs for on - site sampling and testing
• Submit a supplementary statement of compliance with the ISO 2638:2015 standard

V. Import Trend Warning in 2024

As a core component of the automotive transmission system, the import demand for Inner CV Joint (Inner Constant Velocity Joint) has been continuously increasing with the expansion of the Chinese automotive aftermarket. Data in 2023 shows that the domestic high - end vehicle maintenance market has a 65% import dependence on original factory/high - precision CV joint parts. However, due to the complex product technical specifications, many customs classification disputes, and strict certification requirements, importers often face risks such as high demurrage fees, return of goods, and even administrative penalties.

Internationally - recognized Safety StandardsStrengthening of customs AI bill review：Incomplete declaration elements will result in direct return of the bill
Regional Mandatory CertificationsCarbon footprint certification requirements：For EU - imported parts, carbon emission data of the production process needs to be provided
Cultural and Religious NormsUpgrading of origin verification：For goods transshipped in Southeast Asia, a complete processing procedure certificate needs to be provided

Conclusion
Importing inner constant velocity joint parts is not only a technical battle but also a compliance battle. Choosing an agency service provider with special qualifications for auto parts (it is recommended to check its AEO certification and auto - industry service case library) can reduce the comprehensive import cost by more than 40%. It is recommended that enterprises establish a trinity import management system of “technical parameters - customs code - tax planning” to seize the initiative in the supply chain in the fierce competition.
