What import regulation codes commonly appear in Chapter 81?
Import regulation codes are marked on the tariff line and indicate inspection, quarantine, permit, or mainland China import controls that may need to be handled before import. A code may apply only to some of the goods under that tariff line — click into the tariff line for the full description. A tariff line with no code means import is permitted and no permit is required from a trade-control standpoint, but this does not mean the goods are exempt from inspection, quarantine, or duty.

MW0 does not mean nothing can be shipped at all. MW0 = import from mainland China is prohibited. Exception: small quantities of mainland Chinese goods in Chapters 25–97 may be imported without an import permit if the whole declaration is within CIF NT$32,000 and each single product is within 24 pieces (40 kg if it cannot be counted; a single product is identified by its model number, or by the line item on the declaration if there is no model number, and may not be split by size, specification or colour; stone under heading 6802 and tiles under heading 6907 must meet both 24 pieces and 40 kg). Electric motorcycles, electric bicycles and their controllers (tariff lines 8711.60.10, 8711.60.20 and 8543.70.99.50) are excluded, and Chapters 1–24 do not qualify. Inspection, quarantine and other import requirements must still be met separately. This does not mean the goods are duty-free.

What's the difference between Column 1, Column 2, and Column 3 tariff rates?
General Rule 2 of the Customs Import Tariff divides rates into 3 columns: Column 1 applies to imports from World Trade Organization members or from countries or regions with reciprocal treatment toward Taiwan; Column 2 applies only to “specific” imports in two situations: specific goods from certain least-developed or developing countries or regions, or specific goods from countries or regions that have signed a free trade agreement or economic cooperation agreement with Taiwan; goods that do not qualify for either of the first two columns are subject to Column 3. Where both Column 1 and Column 2 could apply, the lower rate is used. Mainland China is a World Trade Organization member and generally falls under Column 1; Column 2 applies to mainland China only for goods on the ECFA Early Harvest list.
The chapter and tariff-line pages on this site display Column 1 rates. Column 2 marks eligible countries in the tariff table using country codes, for example “Duty-free (PA,GT,NI,SV,HN,NZ,SG)”; the codes are only labels in the tariff table, and some of the underlying agreements have been suspended or terminated (e.g., Nicaragua, El Salvador, Honduras) — actual eligibility is subject to Customs Administration announcements. Miscellaneous items in postal parcels have separate rules: when the dutiable value exceeds the duty-free threshold, a 5% rate applies, except for tobacco, alcohol, and goods subject to a tariff rate quota; however, if a single item or items under the same tariff line total more than NT$2,000, they are not treated as miscellaneous items and are instead taxed at each tariff line's own rate (General Rule 5; Regulations Governing Customs Clearance of Postal Parcels, Articles 8 and 9). This 5% rule only covers postal parcels and passengers' goods; express shipments are calculated by each tariff line's rate.
Frequently Asked Questions
- Customs duty: for ad valorem tariff lines, dutiable value × rate; for specific-duty tariff lines, calculated by quantity or weight (imports from mainland China generally apply Column 1).
- Business tax: levied on the dutiable value plus customs duty, collected by Customs on the government's behalf (Value-added and Non-value-added Business Tax Act Article 20 and Article 41); goods also subject to commodity tax or tobacco and alcohol tax have those amounts added to the tax base as well.
- Trade Promotion Service Fee: the statutory cap is 4.25 per 10,000 of the goods' value (Foreign Trade Act Article 21); it is currently charged at 4 per 10,000 of the dutiable value, and waived when the amount payable does not exceed NT$100.
- If the same taxpayer receives duty-free release more than 6 times within the same half-year period (January–June or July–December), imports after that point in the period are no longer duty-exempt (Ministry of Finance Order Tai-Cai-Guan-Zi No. 1061011007 dated May 26, ROC year 106 (2017)).
- A single express shipment may not be split and declared separately (Article 14 of the Regulations Governing Customs Clearance of Air Express Cargo).
- When a postal parcel exceeds the threshold, the entire parcel is taxed in full, not just the amount over the threshold (Article 8 of the Regulations Governing Customs Clearance of Postal Parcels).
