1Overview

  • Destination duty: 0% (Column 2, 85044091007)
  • Business tax (營業稅): 5%
  • This code covers: Other power supply
  • Regime to watch: Taiwan express low-value exemption and frequency capExpress consignments up to NT$2,000 are duty free, but a consignee exceeding six such entries in a half-year loses the exemption and moves to formal declaration.web.customs.gov.tw

Key points

  • De minimis: a consignment with a dutiable value of NT$2,000 or less is free of duty, business tax and commodity tax. More than six such exempt releases by the same taxpayer in a half-year makes them a frequent importer, and the exemption stops.
  • Business tax is 5%, collected by customs. A trade promotion service fee of 0.04% also applies, plus commodity tax on listed categories and tobacco and alcohol tax.
  • Using a customs broker is not mandatory; the taxpayer may file directly, but the declaration still goes through the Single Window electronically.
  • Express consignments are graded by dutiable value: X1 (documents), X2 (NT$2,000 or less, exempt), X3 (NT$2,001 to 50,000, dutiable) and X4 (over NT$50,000, which requires a full import declaration).
  • Before importing from mainland China, check whether the import regulation column of the commodity classification table shows MW0 or MP1.

6Procedure

  1. Advance cargo data and storageThe carrier transmits the manifest, and after discharge the goods enter a container terminal, wharf or bonded warehouse.
  2. Delivery order and documentsExchange the bill of lading for a delivery order and assemble the invoice, packing list, certificate of origin and any import permit.
  3. File the import declarationThe broker or the importer transmits the import declaration through the Single Window, within 15 days from the day after the conveyance's import date.
  4. Clearance channelThe system assigns C1 (release without review), C2 (document review) or C3 (physical examination, either manual C3M or scanned C3X). Goods requiring inspection wait for the competent authority's result.
  5. Pay duty and taxesPay the import duty, business tax, commodity tax where applicable and the trade promotion service fee. Online payment is available, as is release before payment where the rules allow it.
  6. Release and collectionAfter the release notice the goods are collected from the terminal. Amendment, refund and post-clearance audit procedures follow separately.
  1. Manifest and storageThe airline transmits the manifest and the goods enter the air cargo terminal.
  2. Documents and declarationAssemble the documents and transmit the import declaration through the Single Window; the same 15-day deadline applies.
  3. Channel and examinationThe declaration is routed C1, C2 or C3. Goods regulated by BSMI or TFDA must complete their inspection procedure.
  4. PaymentPay the duty, business tax and related fees.
  5. ReleaseCollect the goods from the air cargo terminal.
  1. Express categoriesConsignments are graded by dutiable value: X1 (express documents), X2 (NT$2,000 or less, exempt), X3 (NT$2,001 to 50,000, dutiable) and X4 (over NT$50,000).
  2. Simplified or full declarationX1 to X3 may use a simplified declaration. X4, and anything involving an import regulation, drawback, quota, special duties or the special goods and services tax, requires a full import declaration.
  3. Exemption and frequent-importer testA dutiable value of NT$2,000 or less is exempt, but more than six exempt releases by the same taxpayer within a half-year ends the exemption. Tobacco, alcohol and tariff-quota agricultural products never qualify.
  4. PaymentWhere tax is due, the express operator normally pays and recovers it from the consignee, or the consignee pays directly.
  5. Goods subject to inspectionElectrical goods and other items on the BSMI inspection list bought online still need inspection or an inspection waiver; without it they are not released and a penalty may follow.
  1. Declaration on arrivalTravellers carrying dutiable or declarable goods use the red channel and complete a declaration form.
  2. AllowanceAdult travellers' personal baggage with a total dutiable value of NT$20,000 or less is exempt; alcohol and tobacco have separate quantity limits.
  3. Commercial goodsGoods that are not for personal use follow the ordinary import procedure even when hand-carried, and must meet the import regulation and inspection requirements.
  4. PaymentAnything above the allowance is valued by customs on arrival and the tax is paid on the spot.
