Avoiding cargo rejection: a shipper's biosecurity compliance checklist

Fumigation team reviewing cargo compliance documents

A rejected shipment is one of the most expensive things that can happen to a trader. Beyond the cost of re-treatment, there's demurrage, storage, re-booking, missed contracts and the reputational hit of a late delivery. The good news is that most rejections come down to a handful of avoidable issues. Use this checklist to keep your cargo moving.

Before you book

  • Know the destination's requirements. Every country — and often every commodity — has its own accepted treatments and tolerances. Confirm them before you commit to a shipping date.
  • Check for seasonal measures. Windows such as the BMSB risk season can change what's required based on arrival dates, not order dates.
  • Verify your packaging. Solid-wood packaging and dunnage must meet ISPM-15. Don't assume a supplier's pallets are compliant — check the stamp.

Before treatment

  • Identify the right fumigant and dose. The commodity, pest risk and destination all shape the correct treatment.
  • Confirm the enclosure holds gas. Whether it's a silo, container or tarped stack, gas retention is what makes a treatment effective.
  • Use an approved, licensed provider. Only treatments carried out and certified by an approved fumigator will be recognised.

Documentation is half the battle

A treatment that was done perfectly can still cause a hold if the certificate is wrong. Make sure certification details exactly match the physical consignment — quantities, descriptions, container numbers and treatment data all need to line up.

Before departure and on arrival

  • Keep records together. Treatment certificates and phytosanitary documentation should travel with the shipping paperwork.
  • Allow time for clearance. Build treatment and certification into your schedule rather than leaving it to the last cut-off.
  • Have a contact who can act fast. If something is queried, a 24/7 provider can be the difference between a short delay and a rejected load.

Biosecurity compliance isn't complicated, but it is unforgiving — small oversights create big costs.
