1Overview

  • Destination duty: 1.6% (FTA 협정세율 - 중국, 8518400000)
  • VAT (부가가치세): 10%
  • This code covers: Other audio-frequency electric amplifiers

Key points

  • Small-consignment exemption: goods value of US$150 or less for self-use items, and US$200 or less for goods of U.S. origin under KORUS. Same-day shipments from the same sender are aggregated.
  • Import VAT is 10%, charged on the customs value plus duty plus any individual consumption or liquor tax.
  • A customs broker is not mandatory. The importer may self-file in UNI-PASS, and an individual needs a personal customs clearance code.
  • FTA preference needs a certificate or declaration of origin: KORUS for U.S. origin, the Korea-China FTA or RCEP for Chinese origin. Korea and Taiwan have no agreement, so the basic or WTO rate applies.
  • Whether a product requirement applies depends on the HS code. Food, cosmetics, electrical goods and radio equipment must clear their agency requirement before customs clearance can proceed.

  • · Tax base = customs value (CIF) + duty + individual consumption tax, liquor tax, education tax and special rural development tax where they apply.
  • · Duty is calculated at whichever rate in the tariff schedule applies: basic rate (A), WTO rate (C), or an FTA preferential rate.
  • · Small self-use consignments may instead be assessed at the simplified combined rate under Article 81 of the Customs Act, which rolls duty and internal taxes into one figure.
  • · Individual consumption tax applies only to listed goods such as certain cosmetics, precious metals and vehicles; alcohol carries liquor tax and education tax separately.
  • · A business importer can normally credit the import VAT as input tax, so the final cost differs between businesses and individuals.

6Procedure

  1. Arrival and manifestThe carrier or forwarder files the cargo manifest before arrival and reports discharge once the vessel is in.
  2. Entry into a bonded areaThe goods move into a bonded area such as a CY, CFS or bonded warehouse. A declaration can be filed from that point, or earlier as a pre-arrival or pre-departure declaration when speed matters.
  3. Import declarationThe importer or a customs broker files the declaration in UNI-PASS with the HS code, customs value, origin, the rate claimed including any FTA preference, and any product requirement.
  4. Document review and examinationThe declaration is routed as paperless, document review or physical examination. Goods subject to a product requirement wait until the relevant agency has confirmed it.
  5. PaymentDuty, VAT and any internal taxes are paid. With security lodged, deferred payment including monthly consolidated payment is available.
  6. Acceptance and releaseOnce the import declaration certificate is issued the goods leave the bonded area. Amendment, refund claims and duty drawback follow their own separate procedures.
  1. Arrival and discharge reportThe airline files the manifest and reports discharge, and the goods move into the airport bonded cargo terminal.
  2. Import declarationThe declaration is filed in UNI-PASS, with the same pre-arrival option as for ocean cargo.
  3. Review, examination and requirementsAgency confirmation is obtained where a product requirement applies. Because air cargo moves quickly, the requirement step is often the constraint.
  4. Payment and acceptanceTaxes are paid and the import declaration certificate is issued.
  5. ReleaseThe goods leave the airport bonded area.
  1. Express clearance listThe express operator submits the clearance list to customs before arrival. For an individual importer it must carry the personal customs clearance code.
  2. Choosing the trackLow-value self-use goods go through list clearance; everything else goes through a simplified or a full declaration. Goods excluded from list clearance, such as medicines, health functional foods, some foods and cosmetics and electrical goods, must be declared regardless of value.
  3. Exemption testSelf-use goods with a goods value of US$150 or less, or US$200 or less for U.S. origin, are free of duty and VAT. Same-day shipments from the same sender are added together for the test.
  4. Assessment and paymentAbove the threshold the whole value is taxable, and small self-use consignments may be assessed at the simplified combined rate. Express operators normally advance the tax and bill the recipient.
  5. Release and deliveryAfter clearance the operator delivers. Goods awaiting an agency confirmation stay in the bonded area until it is issued.
  1. Traveller declarationOn arrival, travellers complete the traveller declaration form or the mobile declaration and declare dutiable goods.
  2. Personal allowanceThe basic allowance is US$800, with separate allowances for alcohol, tobacco and perfume.
  3. Voluntary declarationDeclaring goods above the allowance voluntarily earns a reduction in the duty; failing to declare and being found out attracts a penalty surcharge.
  4. Commercial goodsGoods carried for sale need an ordinary import declaration even when hand-carried, and any product requirement still applies.
Show China export-side steps
  1. Registration and preliminary checksComplete customs registration and any export refund registration; look up the regulatory conditions and refund rate for the commodity code to see whether a licence or statutory inspection applies.
  2. Book, prepare and obtain permitsBook with the carrier and obtain the shipping order, complete packing and marks, and obtain the export licence, dual-use licence and export inspection where required.
  3. DeclarationFile the export goods declaration through the Single Window before loading, either directly or through a customs broker.
  4. Examination and inspectionComply with customs examination, and complete the inspection and quarantine procedure for goods on the statutory catalogue.
  5. Release and departureAfter release the goods are loaded and depart; collect the bill of lading and the declaration close-out data.
  6. Settlement and refundReceive payment and file the export VAT refund claim. The documents and the declaration data have to match.
