1Overview

  • Destination duty: 0% (Column 1, 29362700004) — No preferential agreement with United States — the basic / MFN rate applies.
  • Business tax (營業稅): 5%
  • This code covers: Vitamin C and its derivatives
  • 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 a 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 the import-rule column for MW0 (not permitted) or MP1 (permitted with conditions). For express consignments addressed to an individual, the declaration is only accepted once the consignee has completed real-name verification in the EZ WAY app.

Key points on the origin side

  • No export duty and no export VAT refund, because the United States has no VAT.
  • EEI must be filed in AESDirect when any single Schedule B or HTS line in the shipment exceeds US$2,500, or when a licence is required at any value; the ITN returned by AES must reach the carrier before lading.
  • Classify with Schedule B for the declaration, and determine the ECCN for anything that may be controlled under the EAR.
  • Screen all parties against the OFAC Specially Designated Nationals list and the BIS Entity List and Denied Persons List before shipping.
  • Export records are generally kept for five years from the date of export under 15 CFR 30.10.

Caveats

  • Trade-promotion service fee 0.04% is not collected where the amount payable is 100 TWD or less. The calculator does not apply that floor, because it does not know which currency you typed.
  • Excise and requirement lists are written at the national tariff line, not at HS6. An HS6 code can only give the general picture.
  • A small or personal consignment may go through a different regime with a different tax result — see the routes listed below.
  • De minimis: NT$2,000 per-consignment exemption.
  • Information only, as of 2026-09-09. The rates and the customs value fixed on the entry date control — verify with the customs authority or a licensed broker.
De minimis

NT$2,000 per-consignment exemption

A consignment with a dutiable value of NT$2,000 or less is free of customs duty, business tax and commodity tax. The trade-promotion fee is in practice not collected in this range either, because of its NT$100 floor.

· More than six such duty-free releases by the same taxpayer within a half-year (Jan–Jun / Jul–Dec) triggers a 頻繁進口 designation and the exemption is withdrawn.

· Alcohol, tobacco and tariff-quota agricultural products are excluded regardless of value.

  • EZ WAY real-name verification — required for individual consignees

    An import express consignment addressed to an individual is only accepted for declaration once the consignee has completed real-name verification in the EZ WAY app, binding a mobile number to an ID or residence-permit number. Without it clearance is held until corrected. Basis: 空運快遞貨物通關辦法 §17(3); enforced in the clearance system since 2020-05-16.

Information, not advice. What is actually charged is fixed by Customs on the dutiable value and the rates in force on the entry date. 貨物稅 and 菸酒稅 fall only on goods listed in their statutes, which an HS6 code cannot settle. Verify with the Customs Administration or a licensed 報關業者.

As of: 2026-09-09

  • · Business tax = (dutiable value + import duty + commodity tax or tobacco and alcohol tax + tobacco health and welfare surcharge) x 5%, collected by customs under Article 41 of the Business Tax Act.
  • · Trade promotion service fee: 0.04% (four per ten thousand) of the customs value, under art. 21-1 of the Foreign Trade Act and art. 17 of its enforcement rules; it is not collected where the amount payable is NT$100 or less.
  • · Commodity tax applies only to the categories listed in the Commodity Tax Act, such as electrical appliances, vehicles, oil and gas, cement, beverages, flat glass and rubber tyres; the base is the dutiable value plus import duty.
  • · Tobacco and alcohol tax: for example NT$1,590 per 1,000 cigarettes, NT$26 per litre of beer, and NT$2.5 per litre per degree of alcohol for distilled spirits; tobacco also carries a health and welfare surcharge of NT$1,000 per 1,000 cigarettes.
  • · Special goods and services tax of 10% applies to passenger cars, aircraft, yachts and high-value goods above set thresholds.

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 categoriesExpress consignments are graded by customs value into X1 (import express documents), X2 (low-value duty-free, NT$2,000 or less), X3 (low-value dutiable, NT$2,001–50,000) and X4 (high-value, over NT$50,000). X1 to X3 are assigned only the C1 (release) or C3 (examination) channel; X4 can be assigned C1, C2 or C3.
  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.
  6. Consignee real-name verification (EZ WAY)For an import express consignment addressed to an individual, art. 17(3) of the Regulations Governing Customs Clearance for Air Express Consignments requires the consignee to complete real-name verification in the EZ WAY app, binding a mobile number to an ID or residence-permit number. Customs has checked the express-consignment declaration authorisation in its clearance system since 2020-05-16; where the importer is not verified, the declaration is not accepted until the omission is corrected.
  1. Declaration on arrivalTravellers carrying dutiable or declarable goods use the red channel and complete a declaration form.
  2. AllowanceFor an adult traveller, personal and household articles are exempt up to a total customs value of NT$35,000, raised from NT$20,000 with effect from 2024-06-26. Separately, 1.5 litres of alcohol (any number of bottles, travellers 18 and over), and 200 cigarettes or 25 cigars or one pound of tobacco (travellers 20 and over) are exempt; articles the traveller already owned and used abroad are exempt separately where a single article or set has a customs value of NT$10,000 or less. The NT$35,000 exemption does not apply to travellers who are evidently carrying goods for profit or who travel frequently — twice or more within 30 days, or six times or more within half a year. The basis is art. 11 of the Regulations Governing the Inspection, Taxation and Release of Inbound Passengers' Baggage.
  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.
Show United States export-side steps
  1. Classify and screenDetermine the Schedule B number, check whether the item has an ECCN on the Commerce Control List or falls under the USML, and screen the buyer, end user and end use against the OFAC and BIS lists.
  2. Book and documentBook with the carrier or forwarder, and prepare the commercial invoice, packing list and Shipper's Letter of Instruction. Obtain any export licence that applies.
  3. File EEIFile the EEI in AESDirect at least 24 hours before the cargo is loaded onto the vessel, and record the ITN returned by the system.
  4. Deliver and ladeDeliver the cargo to the terminal. The carrier cites the ITN on its outbound manifest; without it the goods should not be laded.
  5. Departure and documentsAfter sailing, collect the bill of lading and send the shipping documents and the origin certification to the buyer for its import clearance.
  6. RecordkeepingKeep the export records, generally for five years from the date of export, and correct the AES filing if the shipment particulars change.
