How long does customs clearance take? Taiwan clearance times and delivery after release

The 9 stages from international dispatch to delivery in Taiwan

“Clearance time” often gets mixed up with international transit and final-mile delivery. Splitting the journey into nine stages shows where a parcel is actually waiting. Each stage varies with the flight or sailing, warehouse operations, declaration details and regulator requirements:

Why has my parcel been stuck on “customs clearance” without moving?

“Customs clearance” usually means that the parcel has entered, or is preparing to enter, the import-clearance process and that customs release has not yet been shown. It may be waiting for authorization, declaration, supplementary documents, permits, inspection, taxes and fees, cargo-terminal processing, or data synchronization. The exact stage must be confirmed with the actual customs broker.

Imported goods must be declared within 15 days from the day after importation (Customs Act, Article 16). After that, a late-declaration fee of NT$200 is charged per day. After declaration routing, C2 document review requires the written declaration to be submitted before the end of customs office hours on the following day. For C3 cargo inspection, a joint inspection must be requested within 10 days from the declaration date. If any stage is incomplete, tracking may remain at “customs clearance.” Taxes and fees must be paid within 14 days from the day after delivery of the tax-payment certificate. Late customs duties incur a late fee of five ten-thousandths per day, while business tax collected by customs incurs an additional 1% for every 3 days overdue.

Official deadlines for the three main hold points

1. Held for supplementary documents: If there is a question about the product description, quantity, dutiable value, or documents, the information must first be corrected or the documents resubmitted. For C2 routing (document review), the written declaration and original documents must be submitted before the end of customs office hours on the following day. Otherwise, processing will be postponed to the next business day.
2. Held for inspection: For C3 routing (cargo inspection), in addition to submitting written documents, you must request a joint inspection with a customs inspection officer within 10 days from the declaration date. The shipment can be released only after review, classification, and valuation.
3. Held for taxes and fees: Payment is due within 14 days from the day after the tax-payment certificate is delivered. Online payment through the Customs-Port-Trade Single Window accepts only tax bills issued within 45 days; after that, payment must be made at a counter or by remittance. Late customs duties incur a late fee of five ten-thousandths per day (Customs Act, Article 74), while business tax collected by customs incurs an additional 1% for every 3 days overdue.

“Customs clearance” is not an official customs status term. The Taipei Customs process chart summarizes the basic procedure as receipt, assessment, inspection, tax collection, and release. Actual cases may also involve authorization, permits, supplementary documents, cargo-terminal processing, and data synchronization. A carrier's general status alone cannot identify the hold point.

In 2013, Tseng Wen-Jui and others at National Kaohsiung University of Marine Science and Technology used the Delphi method in Volume 27 of the university journal to identify 16 risk factors and 21 risk-management strategies in the customs-clearance and pickup process for imported goods. They divided the risk sources into three categories: the goods themselves, missing customs-clearance documents, and the overland transportation stage. In other words, a stalled parcel is not necessarily being reviewed by customs; documentation and inland transportation are also common causes of delay.

What happens after customs release?

After customs release, the release message is sent to the customs broker and cargo terminal. The broker then presents the delivery order at the cargo terminal, pays the storage charges, and collects the goods. Therefore, there are still outbound processing, sorting, and last-mile delivery steps between “released” and “delivered to you.” (Based on the Ministry of Finance Customs Administration article〈How are imported goods taxed and released?〉and the Taipei Customs import-clearance process: receipt → assessment → inspection → tax collection → release.)

Which official time ranges can be treated as customs-clearance time?

Official figures cover different operations. Each number below applies only to the stated process and cannot be added up into a guaranteed parcel-delivery date:

General air or sea imports

No single fixed time

Declarations, C1/C2/C3 routing, duties and taxes, regulatory review, warehouses and carriers differ from case to case. The Customs Administration publishes no single SLA covering every import.

Imported express consignments

Officially described as mostly within a few hours

A Customs Administration FAQ says most express consignments can clear “within a few hours of arrival,” but it does not define the exact starting point of “arrival.” Cases requiring verification, inspection or extra documents are excluded, so vessel or aircraft arrival time cannot be used to calculate a guaranteed release time.

Customs inspection of imported postal parcels

Generally about 1–2 working days

Taipei Customs describes the customs-inspection time for ordinary postal parcels. It excludes postal transport, notification, extra documents, duties and taxes, and final delivery.

Competent-authority processing for food and similar goods

Counted separately by procedure

For example, TFDA publishes processing periods for document review, on-site checks and sampling or laboratory testing. These are regulator processing periods, not an end-to-end customs SLA.

Do not mistake a statutory deadline for a completion time

Deadlines for submitting C2 documents or requesting attendance at a C3 inspection are deadlines for the party concerned, not a customs promise to release the goods within the same number of days. 24-hour clearance operations also do not mean that every manual review, inspection and other authority operates around the clock.

How long does Taipei Port sea-express clearance take? Bali Branch timing

Keelung Customs’ Bali Branch handles import and export clearance at Taipei Port. The official operating rules and HowBridge’s Taipei Port sea-express operating experience are separated below:

Typical case: vessel arrival → customs release / exit from express area

Usually allow 2–4 calendar days

HowBridge’s Taipei Port sea-express operational experience: this period covers berthing, container unloading and deconsolidation, warehouse entry, declaration, X-ray screening, customs release and exit from the express area. This is an operational estimate, not an official customs SLA. Arrivals after Friday or before a long holiday may roll into later staffed working days.

C1 with no X-ray anomaly

Commonly released on the same working day

All sea-express cargo is screened by X-ray first. If a C1 case has no pending authorization, duties, taxes or data issue and the scan shows no anomaly, release often occurs on the same working day that clearance-line processing is completed. This does not guarantee same-day warehouse exit or delivery.

C3 cargo inspection

Commonly about 1–2 additional working days

After cargo reaches the inspection area, the customs broker’s inspection representative assists Customs. When records are complete, scheduling proceeds smoothly and the goods match the declaration, HowBridge commonly sees exit about 1–2 working days later. Time for extra documents, valuation, import-regulation checks or suspected violations is additional.

Does clearance stop completely on Saturdays and Sundays?

Bali Branch’s regular office hours are Monday to Friday, 08:30–12:30 and 13:00–17:00, so routine manual review, inspection scheduling and C3 processing should not count Saturdays or Sundays as normal working days. That does not mean overtime never occurs: urgent cases may apply before a holiday for overtime processing, with staffing arranged by the clearance unit under Customs rules.

X-ray screening is not a separate inspection category alongside C3

In principle, all sea-express cargo undergoes X-ray screening first, regardless of clearance route; simplified express declarations are assigned C1 or C3. C1 with no X-ray anomaly may be released directly. If the scan detects an anomaly, C1 may be changed to C3 and sent to the inspection area. C3 is a cargo inspection selected by the risk system or converted after an anomaly and requires the customs broker’s inspection representative; it is not simply another X-ray pass.

HowBridge operational estimate: “2–4 days” is HowBridge’s Taipei Port sea-express experience from vessel arrival to customs release / exit from the express area. It is not a government-published average or an official customs SLA, and it is not guaranteed. Weekends, container positioning, data synchronization, authorization, duties and taxes, inspections and approvals by other authorities can all extend the timeline.

C1C2C3

Key point: sea freight, sea express and air freight mainly affect transit before arrival in Taiwan. After arrival, unloading, deconsolidation, warehouse entry, declaration and customs procedures still remain. Actual timing depends on the clearance channel, documents, duties and taxes, inspection and on-site operations; customs publishes no fixed number of days applicable to every parcel.

HowBridge measured data: sea freight customs release times

Measured data from HowBridge's own shipments, based on customs timestamps returned by Taiwan's single-window system.

Release to warehouse-out: 50.4% within 24h, 72.4% within 48h (same sample).

Definition: E1 filing accepted → RL customs released, using only event times returned by Taiwan's single-window system (GC329); "2s" means the two system events are less than 2 seconds apart, not how long customs review takes. Covers only declarations already filed with customs (shipments not yet filed, e.g. awaiting consignment confirmation, are excluded), and the data has no clearance-type (C1/C2/C3) code. Cumulative percentiles only; no averages (long-tail outliers distort them). Excludes arrival-to-warehouse and warehouse-out-to-delivery, as current data is insufficient to publish.

What does “customs clearance completed” mean? How long after release / warehouse-out until delivery?

Tracking pages word it differently: “Import customs clearance completed”, “Parcel cleared customs at destination” and “Destination clearance completed” usually mean the same thing — the goods have finished Taiwan customs procedures and moved on to warehouse-out and delivery. If it says “export clearance completed”, the parcel is still in the origin country and has not reached Taiwan; see the FAQ for the difference.

• Release → warehouse-out: after customs release, the warehouse and carrier handle departure and sorting; in our data most parcels complete this within 48 hours (distribution above under “HowBridge real-world data”), but it is not a guaranteed value.
• Warehouse-out → delivered: once in final-mile delivery, timing depends on the carrier, the region and holidays; our current data is not sufficient to publish statistics for this leg — if the status stops updating for a long time, contact the carrier directly.

If tracking shows “left the warehouse” or “warehouse-out processing”, the parcel is usually leaving or has left the customs-supervised warehouse. From then on, follow the warehouse and carrier status. Switch to the carrier’s delivery tracking, or use the clearance-node lookup tool above to confirm the current node.

Is customs open on holidays? Does customs clear goods on holidays and weekends?

• Automated operations: declaration transmission, C1 pick-up and express clearance pick-up can keep running.
• Cases needing human intervention: document review, inspection or additional paperwork may be pushed back, although companies can also apply for overtime processing under the rules.

What gets selected for customs inspection?

According to the Customs Administration, Ministry of Finance (財政部關務署), the customs computer system screens cases using a combination of the company clearance record, the origin of the goods, the nature of the goods and the customs broker involved. No official fixed inspection rate applicable to every parcel has been published, and selection cannot be predicted from price or import frequency alone.

• Clearance record and origin: the customs risk system combines the existing record with the origin of the goods.
• Nature of the goods: goods subject to import regulations, permits, commodity tax or other controls generally require more documents or checks.
• Declared data: where the product description, quantity, value or documents are questionable, correction or inspection may be required.
• Random inspection: customs inspection works on a random-sampling basis; being selected does not mean a violation has been determined.

How do you read clearance progress from the clearance channel?

If your tracking page shows no review and no inspection, there are usually fewer customs steps left. If it shows document review or cargo inspection, you still have manual review, inspection scheduling or document requests ahead. This only tells you which stages remain — it cannot be converted into a fixed number of extra days.

The clearance channel is assigned by customs based on the clearance record, origin, nature of the goods, the customs broker and other risk factors. No official fixed probability or guaranteed number of days applicable to every parcel has been published. Full definitions of C1／C2／C3, simplified declarations, formal declarations and X1–X4 are covered in one place in our guide to simplified and customs declarations.

EZWay advance authorization confirmation: avoid getting stuck on unconfirmed data

Customs Administration press release (February 2026): “Advance confirmation of authorization means that after a consumer buys goods online from abroad, the customs broker first pushes the shipment information to the consumer via the EZ Way app; only after the consumer confirms it matches the actual purchase and completes the online authorization does the broker proceed with the declaration.” — Source: Customs Administration: advance confirmation of authorization fully implemented from 1 March.

What to expect: completing the authorization prevents the declaration from stalling for lack of confirmation, but the actual clearance time is still determined by C1／C2／C3, documents, duties and taxes, permits and inspection. For the full walkthrough see our EZWay tutorial.

What fees does customs clearance involve?

💡 Want a total cost estimate first? Start with our China to Taiwan shipping cost calculator to compare the routes available to you, then use the Taiwan import duty and tax guide to estimate using the correct CCC code. Brokerage, storage and special handling fees still go by the provider itemised quote.

Common reasons parcels get held up, and how to fix them

• Advance authorization not confirmed → verify the data in EZWay; if anything is wrong, contact the customs broker to correct it first.
• Questionable product description, quantity, value or documents → provide order records, payment records, invoices and product specifications so the customs broker can file a correction.
• Duties or taxes assessed but not yet paid → pay according to the official tax notice, never through a link in an unsolicited text message.
• Subject to import regulations or testing → supply the permit, test report or other certificate required by the competent authority.
• Suspected prohibited imports or false declaration → customs decides how to handle it based on the goods and the individual case; do not assume the shipment will automatically be returned or destroyed.

Can AEO benefits guarantee fast release for an individual shipment?

"AEO" (Authorized Economic Operator) is a customs certification programme for trusted businesses. Qualifying importers and exporters may, under the rules, receive a lower document review or inspection rate, priority inspection, a single point of contact and other benefits. But those benefits come with eligibility requirements and conditions, so you cannot conclude that every personal parcel declared by an AEO-partnered broker will clear faster.

• The benefits that actually apply depend on the company category, certification status and the circumstances of the individual case.
• Customs still decides based on the importer, the origin, the nature of the goods, the declared data and the risk system.
• Choosing a customs broker who knows the paperwork and the rules helps reduce data errors, but it is not a guarantee of release time.

HowBridge works with AEO-certified partner customs brokers on these procedures; every shipment is still subject to the customs decision.
