The Clearance Process
Once air cargo arrives at Darwin International Airport (DRW), several documentation, customs and biosecurity steps may need to be completed before the shipment can be released.
Air Waybill and Manifest Lodged
Before or as your cargo arrives, the carrier submits the manifest to the Australian Border Force (ABF).
Import Declaration Lodged
Your customs broker or forwarder submits an import declaration matching the commercial invoice, packing list and air waybill.
Risk Assessment
ABF and the Department of Agriculture, Fisheries and Forestry assess the shipment for customs risk and biosecurity risk. Most low-risk commercial cargo clears without physical inspection.
Biosecurity Screening
Cargo containing timber packaging, plant material, food or other organic content may be held for inspection. See our biosecurity and quarantine guide .
Duty and GST Assessment
Applicable duty and GST are calculated unless the goods qualify for a Free Trade Agreement preferential rate. See Free Trade Agreements & Preferential Certificates .
Release from the Cargo Terminal
Once cleared, cargo is released for pickup or onward delivery — often same-day or next-day at DRW when documentation was correct from the start.
Documents You'll Need Ready
Having the required paperwork prepared before the cargo arrives can help prevent avoidable clearance delays.
- Commercial invoice
- Packing list
- Air waybill
- Certificate of origin, where relevant for FTA claims
- Import permits for regulated goods such as certain foods, plants and chemicals

Why Documentation Errors Cause the Most Delay
Unlike a scheduling delay, a documentation error does not simply cost time. It can trigger a formal hold, storage fees at the cargo terminal and, in some cases, a resubmission cycle that adds days.
Common documentation and clearance problems include:
- Mismatched values between invoice and declaration
- Missing or incorrect tariff classification
- Undeclared organic material triggering an unplanned biosecurity inspection
- Missing import permits for regulated goods
Do You Need a Licensed Customs Broker?
A licensed customs broker is not a strict legal requirement for every shipment, but using one is strongly recommended for anything beyond very simple personal imports.
A broker can help by:
- Pre-lodging documentation so clearance can begin before or as the aircraft lands
- Understanding customs and biosecurity requirements
- Correcting classification or valuation issues before they become a formal hold

Preparation matters. Express air freight cannot compensate for incomplete documentation. Having the correct paperwork ready before arrival can help prevent avoidable clearance delays.
Frequently Asked Questions
Do I need a customs broker for air freight to Darwin?
Not always legally required, but strongly recommended for shipments that are more complex than simple personal imports. A broker can help reduce the risk of clearance delays by ensuring declarations and supporting documentation are prepared correctly.
How long does customs clearance typically take at DRW?
Clearance can often be completed the same day or next day when documentation is complete and accurate. Cargo flagged for physical inspection can take longer.
What happens if my paperwork is incomplete when cargo arrives?
Cargo may be held at the terminal until the required documentation is corrected or submitted. This can create additional delays and may also result in storage fees.
