A single wrong digit in a tariff code, a missing fumigation certificate or an untreated timber pallet can leave your cargo sitting at the wharf while storage charges build up. If you have just received a "Held by Customs" notice, you are not alone. Understanding the common customs clearance delays in Australia is the best starting point for fixing a hold and stopping the next one.
Every import is checked by the Australian Border Force (ABF) and the Department of Agriculture, Fisheries and Forestry (DAFF), and Australia's border and biosecurity rules leave very little room for error. Whether you are a first-time importer bringing in a small parcel or a logistics manager handling FCL and LCL shipments, a customs hold costs you time, money and customer trust.
This guide explains why holds happen, what affects how long they last, and the practical steps you can take to get your goods moving again.
Customs clearance is the mandatory process in which the Australian Government checks that your imported goods are safe, legal and correctly declared, and that any duty and taxes have been paid. For a full walk-through of each stage, see our customs clearance step-by-step guide.
In practice, clearance is a digital exchange between your licensed customs broker and two main government bodies:
If either agency spots a red flag, your shipment is placed on hold and becomes stuck in customs until the issue is resolved. Meanwhile, port storage and container charges may keep accruing.
If your tracking status shows a customs hold, it is usually caused by one of the following seven issues.
Paperwork problems are the most common cause of customs clearance delays in Australia. If your documents do not match the physical cargo, or key details are missing, the ABF can hold the consignment until the discrepancy is fixed. Our article on document errors that cause customs delays covers this in more depth.
Pro tip: Ask your supplier to send you the commercial invoice and packing list before the goods leave the country of origin, and have your customs broker or freight forwarder check them while there is still time to fix errors.
Australia is an island nation with a unique environment, so biosecurity import delays are very common, particularly for sea freight. DAFF officers look closely for:
If DAFF suspects a pest or contamination, the container may be directed to an approved facility for unpacking, inspection, cleaning or treatment. This is one of the more serious types of delay because it depends on facility availability, the treatment required and how quickly any non-compliance can be fixed. You can check the import conditions for your product on the Biosecurity Import Conditions system (BICON).
Your goods will not be released until duty, GST and any other taxes owed have been paid.
If funds are not ready, or there is a dispute about the value of the goods, the cargo stays at the wharf or depot. Delays caused by payment issues are almost always avoidable with a little planning.
Under-declaring the value of your goods to reduce duty and GST is a serious offence, and the ABF has good information about typical market values. If you declare high-value electronics at a small fraction of their retail price, expect a customs hold. The ABF may ask for proof of the transaction, such as bank transfer records, purchase orders and correspondence with the supplier.
Some goods are banned outright, such as asbestos-containing products and certain weapons, while others need a permit, such as some medicines, certain lasers and tobacco products. The ABF lists them on its prohibited goods page.
Sometimes the issue is not your paperwork; it is the volume of cargo moving through the system. Clearance and inspection delays tend to increase during busy periods such as:
During these periods, terminals, depots, inspection facilities and carriers handle far more LCL and FCL shipments, so queues for unpacking, inspection and collection can grow.
Even if everything is correct, your shipment may be selected for a random check. This is part of the ABF's compliance and risk-targeting activity, and being selected does not mean you have done anything wrong. Our guide to the customs inspection process in Australia explains what happens next.
The construction sector accounts for many customs holds. If you are importing building materials from China to Australia, expect close scrutiny.
Pro tip: Work with a freight forwarder and customs broker who understand the rules for construction materials, and ask your supplier for test reports and certificates before you pay for the goods.
The table below shows how serious different problems can be. The actual delay depends on the port, the agency involved, inspection facility availability and how quickly you can supply what is needed.
| Common error | Customs hold consequence | Delay severity and main drivers |
|---|---|---|
| Missing commercial invoice | Customs cannot assess value or tax, so the entry stops. | Usually minor if the invoice is supplied promptly. |
| Wrong tariff (HS) code | The entry must be amended. A penalty for an incorrect declaration is possible. | Minor to moderate, depending on how quickly the correct code is confirmed. |
| Missing BMSB treatment certificate | Goods directed for onshore treatment, or export. | Serious; depends on treatment facility availability and whether onshore treatment is permitted. |
| Soil or dirt on machinery | Cleaning required at an approved facility. | Moderate to serious; depends on how contaminated the goods are and facility bookings. |
| Random X-ray or physical inspection | Container moved to an examination facility. | Moderate; depends on inspection queues and the type of examination. |
| Unpaid GST or duty | Goods held until payment is received. | Continues until the amount owed is paid. |
Customs and biosecurity rules are national, but local conditions at each port and airport can affect how quickly your cargo moves.
Sydney is one of Australia's busiest gateways for both air and sea cargo.
Our team handles customs and quarantine clearance in Sydney.
Melbourne receives a large volume of retail and consumer goods. Delays can be linked to weather, congestion and industrial action affecting terminals or carriers, which can create backlogs at depots and examination facilities. See our customs and quarantine clearance in Melbourne service.
In Brisbane, agricultural and food imports often attract extra biosecurity attention. In Perth and Fremantle, distance from the east coast and the location of specialist facilities can affect how quickly inspections, treatments or disputes are resolved. Learn more about customs clearance in Brisbane and customs clearance in Fremantle.
A common question is "how long does customs clearance take?" The honest answer is that there is no fixed timeframe. Clearance time depends on the transport mode, the quality of your documents, whether biosecurity or border checks are required, the port or airport, and how quickly duty and GST are paid.
Keep in mind: clearance does not include the time the airline, shipping line, terminal or depot needs to unload, unpack and release the cargo. "Cleared" does not always mean "ready for pickup". For more on hold durations, read how long customs can hold a package.

The best way to deal with a customs hold is to prevent it. Use this checklist for a smoother import. Our guide on how to speed up customs clearance in Australia adds more practical tips.
Do not wait until the ship berths or the flight lands. Your customs broker can usually lodge the import declaration before the goods arrive, so assessment can start while the cargo is still in transit. If the ABF or DAFF raises a query, you have a chance to answer it before the goods reach the wharf or airport.
Before the goods leave the factory, ask your supplier to email the invoice and packing list. Check that:
Choose your broker on expertise, not just on the lowest price. A licensed customs broker lodges entries through the Integrated Cargo System (ICS), communicates with the ABF and DAFF on your behalf and knows how to resolve queries correctly. Read what a customs broker does to understand their role.
If your tracking shows "Held", "Exception" or "Awaiting clearance", do not panic. Follow these steps:
The most likely reasons are incomplete or inconsistent paperwork, such as a missing invoice or vague description, or unpaid duty and GST. Biosecurity concerns, including BMSB treatment requirements and contaminated packaging, are also a major cause of customs holds in Australia.
Customs and biosecurity officers can hold goods for as long as they need to confirm compliance. Routine document or payment holds are usually resolved once the missing information or payment is provided. Holds involving treatment, testing, permits or seizure for legal reasons generally take considerably longer.
You cannot track a shipment on a government website. Use the tracking number from your courier or postal carrier, or contact your freight forwarder or customs broker, who can see the status of your entry in the Integrated Cargo System (ICS).
Common customs hold reasons include:
The most effective step is to lodge your import declaration early, before the goods arrive, with accurate and complete documents. Once a hold is in place, respond to every request quickly and fully. There is no shortcut around a required inspection or treatment.
Oversize freight, such as machinery and vehicles, often needs special biosecurity inspection to check for soil in tyres or pests in hard-to-reach areas. These inspections need specialised bookings and handling, so they can take longer to arrange than inspections for standard cartons.
Not necessarily. Some shipments are selected at random or because the type of goods or origin is considered higher risk. If your documents are accurate and your goods comply, a random check usually ends with the goods being released.
Customs clearance problems cost more than time:
These charges vary by port, carrier, container type and how long the cargo is held. Don't let a missing document or a biosecurity oversight hurt your business. Import rules are complex, but they are manageable with the right partner.
