The rate environment heading into September is not easing — it's still climbing. Carriers have announced two further General Rate Increases for China and Asia to Australia in September, and fresh port call omissions published today confirm that Asia port congestion is continuing to reduce effective capacity on key services. On top of this, the BMSB compliance season begins 1 September with material rule changes, and the Christmas booking window is closing. September demands attention on multiple fronts at once.
Here's what to act on this month.
FCL rates from China into Sydney, Melbourne, and Brisbane entered August at elevated levels following the July surge, and the September rate trajectory is upward, not flat. Carriers have announced two rounds of General Rate Increases for the China/Asia–Australia trade for September:
Combined, that represents approximately USD 1,000 per TEU — or roughly USD 2,000 per 40' container — in announced rate increases across the single month of September alone. These increases apply across North East Asia, South East Asia, the Indian Subcontinent, and the Middle East to Australia.
Whether each round holds in full will depend on space demand and carrier discipline. But with effective capacity being actively reduced through blank sailings and port omissions (see below), the conditions for implementation are in place.
*Rates are indicative. Always confirm all-in pricing including current surcharges at time of booking — quote validity windows remain short.
1. BMSB Season Starts 1 September — And the Rules Have Changed
This is the most operationally urgent item for September. Australia's Department of Agriculture, Fisheries and Forestry (DAFF) has announced the 2026/27 Brown Marmorated Stink Bug (BMSB) seasonal measures, applying to certain goods manufactured in or shipped from target risk countries between 1 September 2026 and 30 April 2027.
The season itself is annual and well understood. What matters this year is that DAFF has introduced several operational changes for 2026/27. Ethyl Formate has been added as an approved onshore treatment option — previously it was only available offshore. The Rolled Goods Policy has been removed: breakbulk cargo must now be loaded within 120 hours of treatment, with the previous additional 48-hour allowance no longer available. Importantly, existing approvals issued during the 2025/26 season are no longer valid.
Any shipment of target high-risk goods from a risk country with a shipped-on-board date of 1 September 2026 or later falls under the new rules. China, Japan, the Republic of Korea, and the United Kingdom continue to be classified as emerging risk countries, resulting in increased random inspections of certain cargo.
The practical risk is straightforward: non-compliant cargo arriving at Australian ports can be re-exported or destroyed. There is no grace period for importers who haven't updated their treatment documentation or briefed their suppliers on the 120-hour loading requirement.
If you import machinery, vehicles, vehicle parts, metal goods, or high-risk categories from BMSB risk countries, confirm your treatment arrangements are in place under the 2026/27 rules before your next shipment leaves origin. Contact your KLN Oceania contact for current DAFF guidance and treatment provider details.
2. Two More GRIs Land in September — On Top of an Already Elevated Base
The surcharge stacking that characterised Q3 hasn't stopped. With GRIs of approximately USD 500 per TEU announced for both 1 September and 15 September, importers who haven't reviewed their landed cost models since Q2 are now working with numbers that are materially out of date.
PSS and BAF surcharges from July remain in play. The September GRIs layer on top of these, not in place of them. The all-in cost of a China–Australia FCL shipment in September is higher than in August, and mid-month increases mean quotes from early September may not reflect what ships in the second half.
Request current all-in quotes at the point of booking, not at the point of cargo readiness. For any purchase orders or supplier pricing agreements still based on H1 rate assumptions, the gap between those figures and current landed costs needs to be measured and accounted for before Q4 commitments go out.
3. September Is the Final Pre-Christmas Cargo Window
For most Australian retailers and distributors, goods need to arrive in Australia by October to allow adequate time for customs clearance, domestic freight, and warehouse processing ahead of November-December trading. That means the booking window for Christmas-critical stock is closing now.
Many businesses are preparing for spring and summer stock movements, and September sits at an important point in the freight calendar — it is the final realistic window to get Christmas-season inventory on the water.
With China-Australia transit times of 20–27 days on regular services, cargo that hasn't been booked and confirmed by mid-September carries real risk of arriving too late for peak trading. If you have outstanding purchase orders for Q4 goods, the freight booking conversation needs to happen this week.
4. Congestion Is Now Impacting Both Ends of the Supply Chain
The disruption picture for September has two fronts — Chinese origin ports and Australian destination ports — and both are deteriorating at the same time.
At origin in China: Shanghai and Ningbo have been hit hard by typhoon activity, creating severe vessel bunching and berth queues. Terminal delays at the worst-affected ports are currently running as long as 8 days for a vessel to secure a berth — before any sailing time. As confirmed by ANL's service notices published today, this congestion is already forcing port call omissions on key Australia-bound services: the A3N is dropping its Shanghai call for 6 weeks, and the ACX is dropping Qingdao for 5 weeks. Shekou port has separately imposed limits on vessel exchange — restricting the number of containers loaded and unloaded per vessel call — which will tighten equipment availability in South China in the weeks ahead.
The consequence is that roll pools are growing fast. Shipping lines are currently carrying cargo backlogs of more than 2,000 TEU per carrier. If your goods are not confirmed on a named vessel with a firm load, they are competing against a significant queue of rolled cargo.
At destination in Australia: Brisbane is currently the worst-performing East Coast port, with vessel bunching from off-schedule arrivals creating localised congestion and extended turnaround times. Melbourne and Sydney are operating but under pressure from strong import volumes and the same schedule unpredictability flowing from Asia. These conditions are not resolved by the time a vessel departs — they are waiting for it when it arrives.
What this means for transit times: The table below reflects KLN Oceania's current estimated transit times, incorporating buffer for schedule reliability, observed delays, and port congestion — these are not proforma times.
| Origin | Destination | Weighted Estimate | Worst Case | Notes |
|---|---|---|---|---|
| Shanghai | Melbourne | 25 days | 37 days | Typhoon season (Sep–Oct): add 3–5 days |
| Ningbo | Melbourne | 24 days | 35 days | Typhoon season (Sep–Oct): add 3–5 days |
| Qingdao | Melbourne | 28 days | 38 days | — |
| Shenzhen | Melbourne | 23 days | 34 days | — |
| Shanghai | Sydney | 25 days | 37 days | Typhoon season (Sep–Oct): add 3–5 days |
| Ningbo | Sydney | 24 days | 35 days | Typhoon season (Sep–Oct): add 3–5 days |
| Qingdao | Sydney | 30 days | 41 days | — |
| Shenzhen | Sydney | 23 days | 30 days | — |
| Shanghai | Brisbane | 31 days | 41 days | BNE congestion adds 3–7 days; typhoon adds 3–5 days |
| Ningbo | Brisbane | 29 days | 40 days | BNE congestion adds 3–7 days; typhoon adds 3–5 days |
| Qingdao | Brisbane | 38 days | 47 days | BNE congestion adds 3–7 days |
| Shenzhen | Brisbane | 30 days | 36 days | BNE congestion adds 3–7 days |
Estimates = KLN Oceania analysis based on carrier proforma plus buffer for current conditions. Worst case = P90 estimate across all services for that port pair. Use for contingency planning, not promise dates.
Any delivery commitment or inventory arrival plan built on standard proforma transit times is currently wrong. Use the weighted estimates as your planning baseline and the worst-case column for anything time-sensitive.

September is a month of transition. The acute cost pressure of Q3 is easing, but the compliance and planning demands are just as significant. BMSB adds a documentation and treatment layer to every relevant shipment from 1 September. The Christmas booking window closes this month. And while rates are stabilising, they haven't returned to H1 levels — meaning anyone still operating on first-half cost assumptions is working with an inaccurate landed cost picture.
The importers best positioned heading into Q4 are those who have done three things: updated their landed cost models to reflect current rate and surcharge levels, confirmed BMSB compliance arrangements for Q4 shipments, and placed Christmas-cycle bookings before mid-September.
Rates are not yet past peak on the China–Australia trade. With two GRI rounds announced for September and port congestion at Asian origins actively disrupting services and compressing effective capacity, the conditions that drove Q3 rate increases remain in place. Whether October brings relief will depend on how quickly congestion clears and whether carrier pricing discipline holds against any demand softening.
The practical position for September: the cost environment is still moving, compliance requirements are in force from day one, and the Christmas cargo window is closing. Importers who act this week — on BMSB documentation, Q4 bookings, and current rate confirmation — are in a fundamentally better position than those waiting for the market to stabilise first.
The congestion at Chinese origin terminals — particularly Shanghai and Ningbo following typhoon activity — adds a layer of supply-side risk that goes beyond carrier capacity management decisions. It is weather- and infrastructure-driven, which makes it harder to predict and slower to resolve. With typhoon season running through September and October and Brisbane's structural congestion unresolved, the second half of Q3 is not the time to plan to tight transit windows.
