Custom clearance tips to save time and money on your imports

Custom clearance tips to save time and money on your imports

Efficient customs clearance can make or break your import strategy. From delayed shipments to unexpected duties, even small oversights can lead to costly setbacks. 

With over 50 years of experience in international freight, Stockwells helps businesses navigate complex import and export regulations with ease.

Our in-house customs brokers manage documentation, tariffs, and quarantine procedures and moving on time. Understanding how to plan ahead and work with an experienced broker can save you valuable time and money.

We asked our experts to share their customs clearance tips to help you avoid the most common and costly pitfalls. 


Tip 1: Confirm import and quarantine requirements before you order

This is one of the most common mistakes importers make. Certain products are subject to biosecurity, quarantine, or permit requirements that aren’t always obvious at the purchasing stage.

When these requirements aren’t identified early, issues are far more difficult to resolve once cargo arrives in Australia. In some cases, goods may be delayed for inspection, require treatment, or be refused entry altogether. 

Early planning with a customs broker helps confirm whether goods can be legally imported, and what approvals or treatments may be required. 

Tip 2: Don’t assume supplier paperwork is complete or correct

Customs clearance relies heavily on accurate documentation, such as commercial invoices and certificates of origin.

While suppliers often prepare these documents, errors and inconsistencies are common. For example, some suppliers may claim they can’t get a certificate of origin, which saves importers duty. In reality, they just want to avoid paying for the certificate.

Ultimately, responsibility for this paperwork sits with the importer. This is where working with an experienced customs brokerage team makes the world of difference. Stockwells takes the time to:

  • Identify errors
  • Confirm eligibility for duty concessions
  • Ensure documents meet Australian customs requirements

We’re on your team, working with you to prevent your shipments from being held, delayed, or fined.

Tip 4: Check supplier-provided HS codes

Too many importers assume the HS codes listed on commercial invoices are correct. However, these codes are often wrong.

Incorrect classification can lead to overpaid duty, penalties, or shipment holds. Reviewing HS codes before lodgement is a critical part of a streamlined customs clearance journey.

In one case, a Stockwells client importing ceramic mugs had been paying duty unnecessarily. After review, the goods were correctly classified as ceramic rather than porcelain or china, making them eligible for a Tariff Concession Order. The result was a $40,000 duty refund for our client. 

Tip 5: Start customs planning earlier than you think

Even if you’re only considering importing a product, it’s worth checking requirements with a customs broker first. Don’t assume everything will be fine on arrival.

Early checks help confirm import eligibility, documentation needs, and potential costs before goods are purchased or shipped.

Tip 6: Understand how technology supports clearance

Customs clearance has shifted from manual, paper-heavy processes to digital systems. Working with a customs broker that understands how to utilise this new technology can increase speed and accuracy across your supply chain. 

AI-driven tools now assist with classification, risk assessment and suggesting possible HS codes. Electronic Data Interchange enables real-time submissions of customs documents, cutting processing times by up to 62% and also reducing human error.

These advancements have helped reduce clearance costs, minimise delays, and improve time to market, particularly when paired with experienced oversight.

Tip 7: Avoid unlicensed brokers

Importers who attempt to self-clear or use unlicensed brokers face significantly higher risk. Misclassified goods, incorrect customs values, or missed declarations can lead to penalties, seizure of goods, or prosecution under the Customs Act 1901.

Australia’s quarantine regime is among the strictest globally, and missing a single BICON condition or fumigation certificate can result in costly delays, re-exportation, or destruction of goods.

Not only are licensed brokers legally permitted to lodge import declarations, they also provide essential safeguards through:

  • Correct tariff classification and valuation
  • Knowledge of biosecurity requirements
  • Liaison with ABF and DAFF
  • Accountability under strict licensing conditions

Tip 8: Stay across changes to quarantine and customs legislation

Customs and biosecurity rules change regularly, and even small updates can affect clearance outcomes. 

Recent changes include new Illegal logging requirements for timber products, tighter controls on offshore treatment providers, and stricter enforcement of seasonal biosecurity measures and TCO classification.

Missing or misunderstanding these updates can result in delays, re-treatment, re-exportation, or penalties. Staying informed, or working with a broker who does, helps avoid costly surprises.

Tip 9: Choose a customs partner that keeps you informed

Clear communication is critical to a smooth customs journey. Importers benefit from knowing what’s required upfront, where their shipment sits during clearance, and when conditions change.

At Stockwells, this visibility is built into the process. Clients receive clear guidance before shipments move, proactive updates as cargo progresses through clearance, and early notice of any potential issues. 

Dedicated account management, market alerts, and real-time tracking help businesses plan ahead, respond early, and move through customs with confidence.


If you’re unsure how these considerations apply to your next shipment, speaking with an experienced customs brokerage team early can make all the difference. For tailored advice on your next shipment, reach out to Stockwells at [email protected].
