Port congestion, avoidable delays and paperwork problems cost Australian businesses dearly. For an importer, every unexpected storage charge, re-export bill or compliance penalty comes straight out of your margin. The good news is that most of these losses trace back to a handful of freight forwarding mistakes that are easy to prevent once you know what to look for.
Border rules keep changing. Biosecurity measures for seasonal pests are reviewed every season, restrictions on certain chemicals have tightened, and customs data checks are more thorough than many importers expect. A single paperwork typo, a misunderstood Incoterm or a pallet of untreated timber can leave your cargo stuck at the wharf while storage and demurrage charges build up.
Whether you are bringing in your first container or your fiftieth, this guide walks through the ten most common freight forwarding mistakes importers make in Australia, explains why each one hurts, and shows you how to avoid it so your supply chain keeps moving.
Most import problems are not caused by the ship, the plane or the truck. They are caused by information arriving late, being incomplete or being wrong. When that happens, your goods sit in a terminal or depot while the problem is fixed, and the charges keep running.
The cost of a mistake usually depends on how long the cargo is held, which charges apply at that port or depot, whether an inspection or treatment is ordered, and whether the goods have to be re-exported or destroyed. That is why prevention, not cure, is the cheapest strategy. If you want a deeper look at what holds cargo up at the border, read our guide to common customs clearance delays in Australia.
If you import from Europe, North America or parts of Asia, the brown marmorated stink bug (BMSB) is one of the biggest biosecurity risks you will deal with. The Department of Agriculture, Fisheries and Forestry (DAFF) applies seasonal measures to target goods manufactured in or shipped from target risk countries. Under DAFF's published seasonal measures, they apply to goods shipped between 1 September and 30 April (inclusive), but the department reviews the measures each season, so always confirm the current details on the DAFF BMSB seasonal measures page.
Many importers assume their goods are exempt because "it was fine last year" or because the product doesn't look like something a bug would shelter in. That is a costly assumption. The lists of target risk countries and target goods can change between seasons, and they cover categories such as machinery, vehicles, parts and many manufactured goods.
If target high risk goods arrive untreated, the options are limited and expensive. DAFF permits onshore treatment only in specific circumstances, such as goods in sealed, six hard-sided containers. Goods shipped as break bulk, in open top or flat rack containers are expected to be treated offshore, and untreated break bulk can be directed for export. Even where onshore treatment is allowed, you face extra handling, treatment and storage costs, plus delays while it is arranged.
How to avoid it:
Australia has introduced tighter environmental controls on certain per- and polyfluoroalkyl substances (PFAS), the "forever chemicals" found in some non-stick coatings, stain-resistant and waterproof textiles, firefighting foams and industrial products. These controls sit under the Industrial Chemicals Environmental Management Standard (IChEMS) managed by the Department of Climate Change, Energy, the Environment and Water.
The mistake here is assumption. Importers often assume their manufacturer knows Australian law, or believe their product is "clean" because it isn't a drum of chemicals. In reality, restricted substances can be hidden in the coating of a frying pan, the finish on a sofa or the seal of a hydraulic pump.
If your goods contain a restricted substance, you may not be able to lawfully import, use or sell them, and you could face compliance action. You may also lose the value of the goods and pay for their disposal.
How to avoid it:
Incoterms might sound like textbook jargon, but they can be the difference between a smooth delivery and a tax headache. The Incoterms 2020 rules set out who pays for freight, insurance and duties, and where risk passes from seller to buyer. If you want a refresher, see our explainer on what Incoterms are.
A classic freight forwarding mistake is agreeing to DDP (Delivered Duty Paid) without understanding what it means at the Australian border.
Under DDP, your overseas seller is responsible for everything, including freight, insurance and the Australian import duty and GST. On paper, the goods simply turn up at your door. The problem is that many overseas sellers are not set up to account for Australian import GST and duty. When the goods arrive, the customs entry still needs a party to lodge it and pay the duty and taxes. If the seller can't, the goods get stuck.
You may then have to engage a customs broker at short notice, pay the GST and duty yourself (even if you have already paid the seller for it), and amend paperwork while storage charges build up.
How to avoid it:
New importers often look at the unit price from the supplier and the ocean freight quote, add them together and set their wholesale price. What they miss is the landed cost, the true total cost of getting the goods into your warehouse.
Common costs that eat into margins include:
If you don't account for these upfront, you might sell at a loss, or with a margin so thin that a single delay wipes out your profit. The Australian Border Force explains the duties and taxes side of this on its cost of importing goods page.

You might call it a "fancy desk lamp", but customs needs to know what it is made of, what type of light source it uses and how it works to assign the correct Harmonized System (HS) code and tariff classification.
One of the most frequent importer mistakes is letting the supplier guess the HS code on the commercial invoice. Suppliers often pick a generic code, or one that suits their own country's tariff, without realising it's wrong for Australia.
How to avoid it:
| Mistake | Potential consequence | What drives the cost |
|---|---|---|
| BMSB non-compliance | Onshore treatment where permitted, or the goods directed for export | Treatment method, container type, handling, storage and any re-export freight |
| Wrong HS code | Duty shortfall, penalties and audit work, or overpaid duty | Duty rate difference, value and volume of imports, and how long the error went unnoticed |
| Missing or incorrect documents | Cargo held at the port or depot until paperwork is fixed | Length of the hold, terminal storage and container detention terms |
| Inadequate packing | Cargo damage and possible insurance claim disputes | Value of the goods, extent of the damage and the policy terms |
| Restricted chemicals (e.g. PFAS) | Goods unable to be lawfully imported or sold | Value of the goods, disposal costs and any compliance action |
Everyone wants to save money, but freight markets are volatile. Chasing the absolute cheapest spot rate online can backfire. Low-priced slots are often the first to be cut when a vessel is overbooked.
This is called getting rolled. Your container stays on the wharf at origin while the ship sails without it, because the carrier prioritised cargo booked on higher or protected rates. Very cheap rates can also come with:
How to avoid it: Look for value, not just the lowest number on the quote. Compare free time, routing, inclusions and the level of support you'll get. A reliable forwarder who answers the phone when things go wrong and keeps you updated is usually worth more than a small saving on the rate. Our guide on how to choose the best freight forwarder in Australia covers what to compare.
"The carrier will pay if they break it, right?" Not necessarily.
This is one of the most dangerous myths in logistics. International carriers have limited liability under the conventions and contract terms that apply to your shipment, and it is often calculated by weight or by package rather than by the value of your goods. If a container of expensive electronics is damaged, the carrier's liability may be a small fraction of what you have lost.
It can get worse. If a ship catches fire, runs aground or faces another serious emergency, the shipowner may declare general average. Under this long-standing maritime principle, all cargo owners on the voyage share the cost of saving the ship and cargo, in proportion to the value of their goods. Without insurance, you may have to provide security before your undamaged goods are released.
How to avoid it: Arrange comprehensive marine cargo insurance before the goods ship. The premium depends on the cargo type, value, route, packing and level of cover, and it is usually small compared with the value it protects. Read more in our guide to freight insurance coverage and why you need it.
Waiting until the ship is berthing at Fremantle or Port Botany before you look for a customs broker is a recipe for customs clearance delays. Clearance involves several steps, and each takes time:
Terminals are busy and are not designed to hold your container while paperwork is sorted. Storage and container detention charges can escalate quickly once free time runs out.
How to avoid it: Send your commercial invoice, packing list, bill of lading and packing declaration to your customs broker as soon as the goods leave the origin port. That gives your broker time to lodge the import declaration and resolve questions before the ship arrives. Our customs and quarantine clearance team can help you get ahead of arrival, and our guide on how to speed up customs clearance in Australia has more practical tips.
Australia has some of the strictest biosecurity laws in the world to protect its agriculture and environment. Using dirty pallets, straw, used fruit cartons or untreated timber packing is a major importing misstep.
If a biosecurity officer opens your container and finds:
The whole shipment can be held. You may have to pay for an inspection, followed by cleaning, fumigation or other treatment, and possibly the destruction of the contaminated packing.
How to avoid it:
Freight, duty and GST usually have to be paid before your goods are released. A common freight forwarding pitfall is assuming you can pay on the same credit terms you have with other suppliers.
On a large shipment, the combined import GST, duty and freight can add up to a significant cash amount due on arrival. If the money isn't ready, your goods sit at the wharf accruing storage while you arrange funds.
How to avoid it:
Underestimating biosecurity rules, particularly the BMSB seasonal measures, is one of the most expensive. Shipping target goods from target risk countries during the season without the required treatment can lead to onshore treatment costs, long delays or the goods being directed for export.
Yes. Carrier liability is limited and often based on weight or package, not the value of your goods. If your cargo is damaged or lost, or general average is declared, you could lose much of your investment without marine cargo insurance.
Pre-clear your cargo. Send all documents (commercial invoice, packing list, bill of lading and packing declaration) to your customs broker as soon as the goods depart, so the import declaration can be lodged and any questions resolved before the vessel arrives. Have funds ready for duty, GST and freight, and book transport early.
You can lodge your own import declaration through the Integrated Cargo System (ICS), but it is complex and errors can lead to delays, penalties or audits. Most commercial importers use a licensed customs broker who understands tariff classification, valuation and biosecurity requirements.
A freight forwarder organises the movement of your goods, booking space on ships, planes and trucks. A licensed customs broker handles the border side, including import declarations, tariff classification, duty and GST, and biosecurity clearance. Many logistics companies, including Omega Cargo, offer both. Learn more about the difference between a freight forwarder and a customs broker.
It depends on the mistake, the value of the goods, how long the cargo is held, the charges at the terminal or depot, and whether inspection, treatment, re-export or destruction is required. A small document error may cause a short delay, while a biosecurity or classification problem can be far more expensive.
Delays depend on the cause, the completeness of your documents, whether an inspection or treatment is required, and how quickly duty and GST are paid. The best way to keep delays short is to lodge accurate paperwork early and respond quickly to any queries.
Importing doesn't have to be a gamble. By avoiding these common freight forwarding mistakes, you protect your margins, your reputation and your delivery commitments to customers. Often, the difference between a profitable shipment and a costly one is a little preparation and the right advice.
