How long does customs clearance take in Taiwan? How many days from customs processing to release? (Historical observation: 2026-09-09)

First, which stage is the shipment at?

After HowBridge sea express leaves the Shenzhen warehouse, it passes through four segments that can be checked separately. Clearance is only one of them; do not treat the whole transit time or the time of the query as the clearance time.

• Shenzhen warehouse dispatch to vessel arrival: sailing schedules are controlled by the carrier; this site has no reliable per-shipment dispatch times to aggregate, so no figures are given.
• Declaration to release (clearance): the sea express operator transmits the simplified declaration to Customs by computer link and must complete it within 1 day counting from the day after devanning is finished (Article 17 of the Regulations Governing Customs Clearance Procedures for Maritime Express Consignments); after Customs “accepts the declaration”, C1／C2／C3 determines whether it is released without review or examination, reviewed on documents, or examined, and once done it is “released”. If a personal express shipment under simplified declaration uses EZ WAY online authorization, the recipient must confirm the authorization first.
• Release to warehouse exit: the goods “exit the warehouse” only after X-ray screening and sorting are completed in the sea express cargo zone, and are then handed to the Taiwan-leg logistics provider (in principle all import and export sea express cargo must pass X-ray screening, except cargo whose nature is unsuitable for X-ray and which has been approved by Customs, Article 3 of the Regulations).
• Warehouse exit to signed delivery: home delivery or convenience store pickup; the time is determined by the logistics provider and the delivery method, and is not part of clearance.

How should you read sea express clearance times?

The following historical sample reflects the observation made on 2026-09-09, not current shipment statuses. This site queries the Customs Port Trade Single Window GC329 with clearance numbers and uses only the event times returned by Customs, not the query time and not estimates.

The table below covers the 517 sea express house bills with complete acceptance and release records (de-identified and aggregated, Taiwan time); another 535 had been accepted but not yet released at the last query and were not tracked further, so they are excluded from the timings, which means this table describes only cases whose observation is complete and cannot be taken as the distribution of all cases.

Keelung Customs’ “Notes on Cross-Border Online Shopping via Sea Express” explains that express cargo is X-rayed piece by piece on a conveyor belt and “can be cleared, released and picked up in only about 5 minutes or so”; that statement assumes honest declaration with no violations, refers to the customs inspection operation itself, and does not use the same start and end points as this table’s “declaration acceptance to release” and “release to warehouse exit”.

The median from release to warehouse exit in this site’s sample is 18.8 hours, which may be related to sailing schedules, devanning, sorting and pickup arrangements; this site has not broken down the causes shipment by shipment.

The following historical sample reflects the observation made on 2026-09-09, not current shipment statuses. Recalculation method: start = customs declaration acceptance (E1), end = customs release (RL); only the procDate / procTime returned by GC329 are used, empty values are not filled in and the query time is never substituted; percentiles take the CEIL(n × percentile)-th record after sorting by duration, and negative durations are excluded from percentiles and percentages.

The data range uses a fixed cut-off at record creation time 2026-09-09 20:00; the 1,052 records map one-to-one to 1,052 house bills, with all five stage codes present and in consistent order.

Of all 1,052 with an acceptance record, at least 501 (48%) were released within 1 minute and at least 166 (16%) were still unreleased 24 hours after acceptance; the final duration of the 535 not tracked to release cannot be determined, so this page does not present a final distribution for all cases.

Confirm authorization first

What situations delay release or warehouse exit?

Among the 517 whose observation is complete, release was mostly completed within 1 minute; the following situations lengthen acceptance to release, or slow down warehouse exit and delivery after release. This site has not broken down the causes of individual cases shipment by shipment; rely on what the carrier or customs broker reports.

• The following historical sample reflects the observation made on 2026-09-09, not current shipment statuses. Being classified for C2 document review or C3 cargo examination: of this site’s 517 complete records, 16 took more than 1 minute from acceptance to release, the longest about 2.7 days; of the 535 censored records, at least 21 were still unreleased 72 hours after acceptance. This site does not have the clearance method code for each shipment and cannot confirm the cause of individual cases.
• For personal express imports declared under the simplified procedure using EZ WAY real-name online authorization, first complete identity verification, check the goods and confirm authorization; the customs broker then handles the subsequent declaration. If these steps are incomplete, contact the broker. Also ask the broker whether another lawful form of authorization is available for your case.
• Zone operating hours: clearance operations in the sea express cargo zone are in principle handled during the office hours of the local customs office (Article 13 of the Regulations); 12% of this site’s release events fell on a Saturday or Sunday, but warehouse exit and delivery are still affected by the zone’s and the logistics provider’s operating hours.
• Article 11 of the Regulations classifies express cargo with a customs value of NT$2,001 to NT$50,000 as low-value dutiable cargo, and above NT$50,000 as high-value cargo. High-value cargo and other cases requiring a regular declaration under Article 12 must use that declaration. Low-value cargo may still use a simplified declaration if none of that article’s grounds requiring a regular declaration apply. The broker should assess how to address discrepancies, additional documents or duty in each case.
