Introduction

Standard background and scope of application

This standard, as the No. 78 Industry Standard issued by the General Administration of Customs in 2023, is formulated to meet the type verification requirements of hydrocarbon lubricants in import and export trade. Mainly applicable to:

Customs classification supervision on imported lubricant products
Quality compliance verification of exported lubricant products
Oil type identification in trade disputes

Comparison of core detection technologies

Method	Detection index	Applicable oil	Equipment requirements
Infrared spectroscopy	Molecular structure characteristic peaks	Mineral/synthetic lubricant	Fourier transform infrared spectrometer
Gas chromatography	Hydrocarbon composition distribution	Base oil	Gas chromatography-mass spectrometry
Elemental analysis	S/N content	Oil containing additives	X-ray fluorescence spectrometer

Key technical innovations

The standard establishes a multi-method combined verification system for the first time:

Differential scanning calorimetry (DSC) is introduced to detect the phase transition temperature of oil products
The judgment threshold of infrared spectrum characteristic peak matching degree ≥90% is specified
The difference index of carbon number distribution between synthetic oil and mineral oil is added

Typical case: In 2024, Qingdao Customs found through GC-MS testing that the actual carbon number distribution of a batch of imported goods declared as synthetic oil did not meet the PAO characteristics, and finally levied additional taxes of 1.27 million yuan.

Implementation suggestions

Corporate response strategies:

Establish oil product technical archives and retain raw material test reports
Perform method validation and pre-testing before import and export
Pay attention to the correspondence between API classification and customs standards

Key points of customs supervision:

Focus on monitoring high-tax oil products (such as HS2710.19.90)
It is recommended to equip portable infrared analyzers for on-site screening
