Shanghai's export container index rose 2.0% to 3,662.18 points on 11 September, a seventh straight weekly gain, as North America stayed near peak levels: Shanghai-US West Coast $7,339 per FEU (+1.3%) and Shanghai-US East Coast $10,479 per FEU (+1.5%). Southeast Asia jumped 13.1% to $1,010 per TEU on pre-holiday restocking, while Europe kept sliding to $2,545 per TEU (-3.7%) and the Mediterranean to $3,299 (-4.2%). US imports reached 2.604m TEU in August, up 3.8% month on month.
Supply Chain Action Points
What this means for your business — and what to do about it:
Shanghai's container index closed at 3,662.18 points on 11 September, up 2.0% week on week and higher for a seventh straight week. Shanghai to US West Coast settled at $7,339 per FEU (+1.3%) and Shanghai to US East Coast at $10,479 per FEU (+1.5%), while Europe slipped to $2,545 per TEU (-3.7%) and the Mediterranean to $3,299 per TEU (-4.2%). US imports reached 2.604m TEU in August, up 3.8% month on month.
That split is the whole story. On the trans-Pacific lanes you are buying scarcity, and the price is still moving up every week. On Europe and the Mediterranean you are buying into a falling market, where waiting has a measurable value. Southeast Asia is the third case: $1,010 per TEU, up 13.1% on pre-holiday restocking, a short squeeze on a lane that used to be the cheap alternative to everything.
The five notes below are written for five different jobs inside one company. Each starts from the numbers above, shows the arithmetic it uses, labels every assumption, and finishes with dated actions and thresholds that can be handed to a desk on Monday morning.
For Exporters
A seventh consecutive weekly gain took SCFI to 3,662.18 points on 11 September, and the trans-Pacific leg did most of the harm: $7,339 per FEU to the US West Coast, up 1.3%, and $10,479 per FEU to the US East Coast, up 1.5%. A 1.3% weekly move looks harmless until it is priced. On a 20 FEU monthly allocation to Los Angeles, $7,339 per FEU is $146,780 of ocean freight; one more week at the same 1.3% adds $1,908 to that same book, before any inland drayage, chassis or fuel charge. Seven weeks of that pattern is why a quote issued in early September no longer covers cost. Your exposure is not the rate itself, it is the gap between the validity you sold and the next general rate increase the carrier files.
Assume a mid-sized exporter moving 40 FEU a month to the US West Coast and 20 TEU a month to Europe. The US book costs 40 x $7,339 = $293,560 a month and the Europe book costs 20 x $2,545 = $50,900, a combined $344,460. Now separate the lanes. If Europe keeps falling at the 3.7% weekly pace recorded by the index, $2,545 becomes roughly $2,189 after four weeks, a saving of about $356 per TEU and $7,120 across 20 TEU. If the US West Coast repeats its 1.3% weekly gain, the 40 FEU book costs $3,816 more in the same month. The falling lane is where the negotiating room sits; the rising lane is where volume has to be locked early.
Cut US lane quote validity to 14 days from 18 September and attach a pass-through clause that names the general rate increase and peak season surcharge, with a stated cap, owned by the commercial manager and applied to every outstanding quote before the next booking window opens. Keep Europe and Mediterranean quotes at 30 days but price them off a published index rather than a fixed number, so the decline reaches the buyer instead of staying in your margin. Split the US book 70% fixed rate with a guaranteed allocation and 30% spot, and take the European spot share to 60% to keep catching the decline. Treat Southeast Asia at $1,010 per TEU, up 13.1%, as a short window: quote small lots with 10-day validity only.
Alternatives are not free. Re-routing European cargo through the Mediterranean at $3,299 per TEU costs $754 per TEU more than direct Europe at $2,545 and only pays when the final customer sits in Italy, Spain or North Africa. Switching US cargo to the East Coast is worse, not safer: $10,479 against $7,339 is a $3,140 per FEU gap. The traps sit in documentation and billing rather than routing. Origin certification must match the actual port of loading, US cargo filings must be lodged against the right bill of lading, and free time starts at discharge, not at your gate, so a slow drayage booking quietly becomes a detention bill. A pass-through clause that names a rate increase without a cap, an effective date and a notice period is a blank cheque written in your own favour until a customer reads it.
- Cut US lane quote validity to 14 days from 18 September, with the commercial manager signing off and all outstanding quotes audited within 5 working days.
- Add a rate-increase and peak-season surcharge pass-through clause with a stated cap and effective date to every US quote issued from 18 September.
- Confirm US West Coast space for the next four weeks by 25 September, targeting 70% fixed rate with guaranteed allocation and 30% spot.
- Keep Europe and Mediterranean quotes at 30 days priced off a published index, and hold 60% of European volume on spot to capture the 3.7% weekly decline.
- Reconcile port of loading against origin certificates and bill of lading data on every US shipment, targeting zero amendments after vessel departure.
- Limit Southeast Asia allocations to 5 FEU per sailing with 10-day validity, so the 13.1% pre-holiday spike cannot lock a full month of volume at the top.
For Cross-Border E-commerce
For a cross-border importer, the East Coast print of $10,479 per FEU (+1.5%) matters more than the index headline, and the West Coast at $7,339 per FEU (+1.3%) sets the floor. Take a 40HQ carrying 1,500 units of small home goods with a $25 shelf price. At $10,479 per FEU the ocean leg alone is $6.99 per unit. One more week at this week's 1.5% pace adds $0.10 per unit and $1,886 across a 12-container month. That $0.10 is 0.42% of the ticket price, gone before any last-mile delivery, payment fee or return cost. Peak volume makes it harder to avoid: US imports reached 2.604m TEU in August, up 3.8% month on month, and all of it competes for the sailings your replenishment plan depends on.
Assume a hero SKU selling 600 units a month with 45 days of cover held in a US warehouse. The freight increase alone does not justify air freight, but it changes the replenishment maths. Moving from one sailing a month to two, on 6 containers per sailing, lifts the buffer from 45 to 60 days, about 300 extra units of working capital at $6.99 of freight per unit plus goods cost. Against that, a stockout on the hero SKU during the pre-holiday restocking window loses the full retail margin on every missed sale, which is far larger than $1,886 a month of added freight. The real decision is not whether to absorb $0.10 per unit, it is which SKUs are allowed to run thin.
By 22 September, reset safety stock for the top 20 SKUs by revenue to 60 days and hold the tail at 30 days, with the supply chain lead owning the change and reporting landed cost per unit weekly. Shift 60% of replenishment volume to the West Coast at $7,339 per FEU and 40% to the East Coast, and book both by the 10th of each month so the pre-holiday build-up cannot set your price. Freeze prices where the 1.5% weekly move changes landed cost by less than 0.5%, and trigger a price review only where it exceeds 1%. Stop replenishing the slowest 10% of SKUs whose freight cost per unit is above 15% of the ticket price.
Alternatives have their own price. Air freight is not a substitute at 1,500 units per container, and Southeast Asia at $1,010 per TEU, up 13.1%, helps importers sourcing there rather than US-bound replenishment. Buffering goods in a bonded or free-zone warehouse buys 15 to 20 days of cover but adds handling and storage per unit, so run it only for the top 5 SKUs. The traps: free time and demurrage are counted from discharge, not from your gate, so a 5-day drayage delay can erase a container's entire freight saving; surcharge billing must state which peak season surcharge applies and from which effective date; and any delivery promise published in September on 45 days of cover will fail in November if the sailing slips by a week.
- Reset the top 20 SKUs by revenue to 60 days of safety stock and the tail to 30 days by 22 September, owned by the supply chain lead.
- Split replenishment 60% West Coast and 40% East Coast, and book both by the 10th of each month.
- Increase hero SKU buffer by about 300 units, funded only for SKUs whose stockout margin loss exceeds the added freight of $1,886 a month per 12 containers.
- Freeze pricing where the 1.5% weekly move changes landed cost by under 0.5%; review only SKUs where it exceeds 1%.
- Delist or pause the slowest 10% of SKUs with freight cost above 15% of the ticket price by 30 September.
- Require a weekly free-time and demurrage report from the 3PL so that no drayage delay exceeds 3 days from discharge.
For Manufacturing Plants
Southeast Asia's jump to $1,010 per TEU, up 13.1%, and the trans-Pacific's seventh weekly gain reach a factory through two doors: inbound components and outbound spares. US import volume of 2.604m TEU in August, up 3.8% month on month, means more cargo chasing the same sailings, so the door-to-door window for inbound components stretches just as production plans firm up for the fourth quarter. Europe at $2,545 per TEU (-3.7%) and the Mediterranean at $3,299 per TEU (-4.2%) are moving the other way, and that is where the cost relief sits for European machinery, tooling and spare parts.
Assume the plant imports two 40HQ containers of European spares a month, which is four TEU at $2,545, or $10,180 a month. If the Europe rate keeps falling at the 3.7% weekly pace shown in the index, month four costs about $8,756 and the four-month total falls from $40,720 to roughly $38,179, a saving of about $2,541. On the inbound US side, assume the door-to-door window lengthens from 35 to 40 days because of the volume surge. Critical raw material cover at 20 days then has to move to 26 days to hold the same line-stop risk, and that is a working-capital decision measured in inventory value, not a freight decision measured in rates.
Before 30 September, place the fourth-quarter European spare parts order one quarter earlier and book four TEU a month on index-linked terms, with the planning manager owning the schedule and the procurement desk owning the booking. Any changeover part with a lead time above 45 days must be on site by 10 November, with at least 26 days of cover held from that date. Re-sequence production so lines running US export orders carry a 10-day finished-goods buffer instead of 5, and have the plant director confirm that buffer weekly against actual bookings rather than against plan.
Alternatives need a written threshold, not a debate during an incident. Air freight is justified only for a part whose line-stop cost per day is higher than the air premium, so state that number in advance. Adding a second port of loading on the same service costs documentation time but no extra freight. Buffering components at a 3PL near the plant trades storage cost for shorter in-plant congestion. The traps: demurrage and detention run from discharge, so a late drayage booking is a real cost; origin documents and tariff classification for spare parts must match the supplier invoice exactly; and in a peak where every buyer is chasing the same suppliers, allocation goes to whoever confirmed the booking first, not to whoever sent the most emails.
- Place the fourth-quarter European spare parts order one quarter early and book 4 TEU a month index-linked, before 30 September.
- Raise critical raw material cover from 20 to 26 days, assuming a 35-to-40-day door-to-door window, and report the working capital impact to the plant director.
- Have every changeover part with a lead time above 45 days on site by 10 November.
- Build a 10-day finished-goods buffer on US export lines instead of 5 days, confirmed weekly against actual bookings.
- Write a line-stop cost per day threshold above which air freight is authorised without further approval.
- Lift key spare parts cover to 26 days by 10 November, owned by the planning manager, and reconcile classification against supplier invoices monthly.
For Brand Owners
A brand selling into the US has to convert $7,339 per FEU to the West Coast and $10,479 per FEU to the East Coast into a delivery date it is willing to publish. Seven straight weeks of increases means the cost side of that promise moves weekly while the promise itself was probably set in August. The $3,140 per FEU gap between the two coasts is the size of the lever available. US import volume of 2.604m TEU in August, up 3.8% month on month, is the reason space rather than price is the binding constraint as the peak builds, and a brand without a confirmed allocation is bidding for capacity it may not get.
Assume the brand plans 20 FEU a month into the US East Coast. Moving that book to the West Coast and running inland rail changes the freight line by 20 x ($10,479 - $7,339) = $62,800 a month. Assume inland rail and drayage add $1,800 per FEU, or $36,000, which leaves a net saving of $26,800 a month. The price is time: a Midwest customer moves from a 3-day post-arrival delivery to roughly 7 days under the same assumption. That is a change to a published promise, so it has to be made deliberately, with new dates on the website, rather than discovered in a customer service queue.
By 25 September, publish two service bands instead of one promise: a 5-day band for coastal and direct-to-consumer orders and a 10-day band for inland, owned by the customer service director, with daily exception reporting on any order that will miss its band. Set a margin rule so that any SKU where the weekly freight move changes landed cost by more than 2% goes to price review within 5 working days, and no promotion is confirmed until space is confirmed. Allocate constrained inventory first to direct-to-consumer and contracted key accounts, then to wholesale, and put that priority order in writing with the 3PL. Require a weekly space and rollover report from each carrier and forwarder, listed by vessel name.
Alternatives all cost something. Holding more finished goods in a US warehouse costs storage but protects the promise. Shipping partial containers protects the date at a worse cost per unit. Extending the published window protects margin but damages conversion, and on a marketplace that also costs ranking. The traps are mostly internal. Promotional calendars are locked 8 to 12 weeks ahead, often before space is secured, which is how a brand ends up paying spot rates to rescue a campaign it already advertised. Retailer chargebacks for late delivery and short shipment can exceed the freight increase itself. And a return rate that climbs because customers received late deliveries quietly cancels out the $26,800 saved by re-routing.
- Publish a 5-day coastal and direct-to-consumer band and a 10-day inland band by 25 September, with daily exception reporting by the customer service director.
- Set a rule that any SKU whose landed cost moves more than 2% in a week goes to price review within 5 working days.
- Confirm space before any promotion is signed off, with no promotional commitment made on unbooked capacity.
- Write the inventory priority order, direct-to-consumer and key accounts first, wholesale second, into the 3PL agreement by 30 September.
- Require a weekly space and rollover report by vessel name from every carrier and forwarder.
- Review the return rate monthly against on-time delivery; if delivery misses lift returns, move volume back to the East Coast at $10,479 per FEU.
For Procurement Teams
Seven consecutive weekly gains put the trans-Pacific at a high-water mark: $7,339 per FEU to the West Coast and $10,479 per FEU to the East Coast, while Europe at $2,545 and the Mediterranean at $3,299 are both falling. The procurement question is not whether rates are high, it is which lanes should be contracted now and which should be left to float. Buying the top of a seven-week rally on an annual commitment is expensive. Buying Europe on the way down locks in a floor you will regret within a quarter, and the gap between the two decisions is what a tender is for.
Assume an annual requirement of 600 FEU split 70% contract and 30% spot. On the US West Coast at $7,339 per FEU, the spot share is 180 FEU, or $1,321,020 a year, and the contract share is 420 FEU. Assume a contract rate 12% below spot, which is a planning assumption rather than a market quotation. Moving 120 FEU from spot to contract saves 120 x $7,339 x 12%, or about $105,682 a year. Run the same logic in reverse on Europe: at $2,545 and falling, commit no more than a quarter of volume, buy the rest on 3-month index-linked terms, and keep 60% floating so the weekly decline is captured rather than locked away.
Open the tender for US West Coast space by 30 September and close it within 10 working days, with the procurement director owning the result and a target of at least 50% of the US book on a fixed rate with a guaranteed allocation. Write index-linked terms for Europe and the Mediterranean against a published index with a stated reference period, adjustment no more frequent than monthly, and a cap of 3% per adjustment. Qualify a second carrier plus one consolidator on each lane before 15 October, so a rollover becomes a switching decision instead of an emergency negotiation.
Alternatives and traps belong in the same clause list. Three carriers on one lane buys resilience but splits volume below the level that earns a real service commitment, so keep the primary carrier above 50% of that lane. A minimum quantity commitment looks like leverage until volumes fall, and dead freight on an unmet commitment can cost more than the rate difference you negotiated. Write these points into the contract explicitly: whether a named general rate increase includes the peak season surcharge, which party pays after free time expires, the notice period for a rate adjustment, and what happens when an emergency surcharge is triggered at the carrier's own discretion. An index-linked clause without a reference period and an adjustment frequency is not protection, it is a promise to argue later.
- Open the US West Coast tender by 30 September and close within 10 working days, targeting at least 50% of the US book on fixed rate with guaranteed allocation.
- Move 120 FEU a year from spot to contract on the West Coast, an expected saving of about $105,682 on the stated 12% assumption.
- Write Europe and Mediterranean terms as index-linked with a reference period, monthly adjustment, and a 3% cap per adjustment.
- Cap European commitments at one quarter of volume and keep 60% floating while the rate falls 3.7% a week.
- Qualify a second carrier and one consolidator per lane before 15 October, keeping the primary carrier above 50% of lane volume.
- Add clauses covering peak season surcharge inclusion, free-time expiry liability, rate adjustment notice, and emergency surcharge discretion to all contracts by 31 October.
