When conducting customs commodity classification,it is crucial to accurately understand and fill in the purpose,function,and principle of the commodity.These elements seem similar,but there are obvious differences between them.Misunderstanding may lead to classification errors,thus affecting the smooth progress of the business.Today,we will talk about these concepts in an easy - to - understand way to help you better understand their declaration requirements.I.Purpose

II.Function

PurposeIn the declaration elements,there are often some prompts for limiting the scope,and special attention should be paid to the content in parentheses.For example: It can be filled as for laboratory use,chemical use,agricultural use,etc.It can be filled as for industrial use,non - industrial use.

• 6909Itcanbefilledasusedforconnectionbetweenpipes.
• 7326Itcanbefilledasformetalprocessing,forwoodprocessing,etc.
• 7307Itcanbefilledasformotorvehicles,forfurniture,etc.
• 8208Itmustbefilledasforelectronicproductssuchasmicroprocessors,telecommunicationsequipment,automaticdataprocessingequipmentordevices.
• 8301Inaddition,forsomecommoditycodes,itisnecessarytospecifythespecificoccasionofapplicationanditsfunctionindetail,especiallyforthedeclarationofmachineparts.Forexample:
• 8414599050Mustfillinforelectronicproductssuchasmicroprocessors,telecommunicationsequipment,automaticdataprocessingequipmentordevices.

In addition,for some commodity codes,it is necessary to provide a detailed description of the specific occasions of use and their functions,especially for the declaration of machine parts.For example: 84733090,8466100000,85030090For these codes,the applicable models need to be declared,that is,they are applicable to a certain model of a certain brand or are commonly used for some equipment,as well as their specific functions.

III.Principle

FunctionIt refers to the role that a commodity can play or the attributes it possesses.It can be simply understood aswhat this commodity can do.The function usually describes the specific use of the commodity or the goal it achieves.For example:

• 90261000Thefunctioncanbedeclaredasplaystheroleofdetectingtheliquidflowrate.

IV.Understanding of Declaration Requirements

PrincipleIt describes the basic working mechanism that a commodity is based on during operation.Simply put,it iswhy it plays such a role.Machines with the same function may have different principles,and under different tariff items,the description of the principle will also vary.For example:

• 8413Theprinciplecanbedeclaredasreciprocating,rotary,centrifugal.
• 8514,8516Theheatingprincipledescribesthewayofgeneratingheatandcanbedeclaredasresistanceheating,inductionheating,resistancelossheating,etc.
• 8528Thedisplayprincipledescribesthespecificwayofthedisplaydeviceandcanbedeclaredascathoderaytube,liquidcrystal,plasma,etc.

Generally refers to the application object or application field of the commodity,or the industry or scope to which the commodity applies.Simply put,it is where this commodity is used.

When making commodity declarations,the customs also has different requirements for use,function,and principle:

• Use(Where):Ifonlyuseneedstobedeclared,thentwoelements,theapplicableoccasionandandspecificfunctionofthecommodityneedtobefilledin.
• Function(What):Thefunctiondescribestherolethatthecommodityplays,thatis,whatthiscommoditycando.
• Principle(Why):Theprincipleisfilledinaccordingtothepromptsinthedeclarationelements,describingthespecificworkingprincipleofthecommodity,thatis,whythiscommoditycanplaysucharole.

V.Summary

When classifying commodities,it is crucial to clarify the differences between use,function,and principle.Use describes where the commodity is used,function is what it can do,and principle is why it can do it.Accurately understanding these elements not only helps improve the accuracy of classification but also avoids troubles and unnecessary costs caused by incorrect declarations.
