1.Case Background: The Particularity of Oil Seal Imports in Taiwan

In June 2022,we represented a machinery equipment manufacturer in importing a batch of oil seals produced in Taiwan.Special attention must be paid to such sealing products during customs declaration: HS code classification (usually under item 4016.93),declaration of rubber material (involving environmental protection requirements),and description of industrial use.Additional preparations are required for importing products from the Taiwan region.ECFABook,which is the key document for enjoying the agreed tariff rates.

In practical operations,we have observed that clients frequently make two common mistakes: first,confusing the classification differences between oil seals and mechanical seals; second,overlooking the special format requirements for certificates of origin from Taiwan.It is precisely these details that determine customs clearance efficiency and highlight the value of professional agency services.

II.Comprehensive Breakdown of the Customs Clearance Process at Yangshan Port

1.Preparation Phase (3 working days)

Output:

Our team completed three core tasks before the goods arrived at the port:

• Checkthedeclarationelements:including8keyparameterssuchasmaterialpercentage,brandmodel,applicabletemperaturerange,etc.
• Pre-reviewofECFAcertificate:ConfirmthatthereisasignaturefromtheTaiwansideinthe"ForOfficialUse"column(Column7)ofthecertificate.
• LabelFiling:Althoughindustrialoilsealsdonotrequirefood-gradelabels,theymustbemarkedas"forindustrialuse"onthecustomsdeclarationform.

2.Customs declaration practical operation phase (0.5 working days)

Output:

Yangshan Port adopts the "pre-declaration" mode,where we complete the customs declaration entry 24 hours before the vessel’s arrival.Special note:

• Themodeoftransportationshouldbereportedas"Waterwaytransport(Code6)".
• Theregulatorymethodisselectedbasedontheactualtradesituation:"GeneralTrade(Code0110)"
• FreightandinsurancepremiumsmustbefullydeclaredattheCIFprice.

3.Inspection Response Strategy (15-18 working days)

Output:

The inspection rate for electromechanical products at Yangshan Port is approximately 30%.We have implemented three measures to reduce inspection time:

• Preparetheproductcross-sectiondiagramandtechnicalparametersheetinadvance.
• Schedulethe"Pre-inspectionEntry"servicetoreduceon-sitewaitingtime.
• Preparethird-partyinspectionreportsforcommoninspectionpriorities(suchasmaterialtesting).

III.Three Key Secrets to Time Node Control

Compared to the industry average of 25 days for customs clearance,the key to our completion in 15 days lies in:

Special reminder: June to August is the peak season for ports each year.It is recommended to allow a 20% time buffer.

IV.Common "Pitfalls" in Seal Imports and How to Address Them

Based on our 15 years of agency experience,the following issues are most likely to occur with the import of oil seal products:

1.Classification disputes

Output:

A customer once mistakenly classified a PTFE oil seal under HS code 3926 (plastic products),resulting in the tariff rate increasing from 8% to 12%.The correct approach should be:

• Rubbercontent>50%isclassifiedunder4016.
• Plasticsaremainlyclassifiedunder3926.
• Metalskeleton-basedreclassificationbymaterialindescendingorderofweight.

2.Determination of origin

Output:

A Taiwanese manufacturer once provided a "Made in Taiwan" statement instead of an ECFA certificate,resulting in the inability to enjoy zero tariffs.We recommend:

• RequestthesuppliertoprovidetheoriginalECFAcertificatewithofficialseals.
• ConfirmthatthemanufacturerisincludedinthelistapprovedbytheMinistryofEconomicAffairsofTaiwan.

V.Value-added Services of Professional Agents

In addition to basic customs clearance,we offer three extended services to our clients:

6.Industry Trends and Recommendations

With the implementation of RCEP,we have observed:

• TheimportvolumeofoilsealsinTaiwanincreasedby15%year-on-year,primarilyreplacingproductsfromJapanandSouthKorea.
• Afterthepilotofthe"SmartPort"atYangshanPort,thecustomsclearanceefficiencyforelectromechanicalproductshasincreasedby40%.
