On September 8, 2026, Canada imposed counter-tariffs of 15%, 25%, and 50% on approximately C$27.6 billion of U.S. goods (about US$20 billion in some wire reports) in response to U.S. trade actions. Steel, aluminum, furniture, and apparel often face the 50% rate; dairy, appliances, agricultural equipment, pulp, paper, and electronics are also on the list. The same booking window now sits under a higher Trans-Pacific print: Drewry’s September 10 World Container Index shows Shanghai–Los Angeles at $7,352 (+2%) and Shanghai–New York at $9,726 (+1%), after the prior week’s jump to $7,185 / $9,587. Drivers remain pre–China National Day (October 1–7) pull-forward, Asia port congestion, and Panama Canal draft and slot limits.
For shippers moving freight from China to the U.S. with transshipment or onward moves into Canada, those two forces — duty stacks and freight surges — arrive in the same booking window. The landed cost you calculated last month is not the landed cost today.
As of September 13, 2026, this is an operational guide for container booking and landed-cost decisions. It is not customs, legal, or tariff classification advice.
Canada's September 8 counter-tariffs: what they cover
Canada's Department of Finance published the full product list on September 8. The counter-tariffs apply to U.S.-origin goods entering Canada and range by category:
| Tariff rate | Product categories (examples) |
|---|---|
| 50% | Steel, aluminum, furniture, apparel, certain manufactured goods |
| 25% | Automotive parts, machinery, certain chemicals |
| 15% | Electronics, consumer goods, selected agricultural products, pulp and paper |
Other affected categories include dairy, home appliances, agricultural equipment, and plastics. The list covers goods valued at ~C$27.6 billion annually.
CUSMA (Canada-United States-Mexico Agreement) preferential treatment does NOT exempt goods from the surtax. Even if a product qualifies for CUSMA preferential duty rates, the counter-tariff is additional and is applied on top of the CUSMA rate.

Trans-Pacific rate surge: China National Day and capacity pressure
Early September saw spot rates on major Trans-Pacific lanes rise week-over-week, driven by multiple operational forces converging before China's Golden Week holiday (October 1–7):
| Lane | Drewry Sep 10 (USD / 40ft) | Trend vs Sep 3 | Drivers |
|---|---|---|---|
| Shanghai–Los Angeles | $7,352 | +2% (after +5% the week before) | Pre–Golden Week pull-forward, Asia congestion, Panama draft / slots |
| Shanghai–New York | $9,726 | +1% (after +3% the week before) | Same plus East Coast space pressure |

CH Robinson's September freight market update flagged additional stresses:
- Typhoon-related port congestion slowing vessel rotations in Asia
- Panama Canal draft restrictions reducing alternate-route capacity for vessels avoiding longer Suez/Cape diversions
- Pre–National Day scramble as Chinese exporters and U.S. importers front-load bookings to avoid the October 1–7 factory shutdown

Separately, Descartes reported that U.S. container imports reached 2,603,709 TEU in August 2026, the third-highest monthly volume on record, reflecting ongoing elevated demand ahead of potential tariff changes and Golden Week.

These are not annual GRI adjustments. They are event-driven capacity and demand pressures that compress available space and drive spot-rate premiums before the Golden Week factory pause.
How the tariff and rate surge interact on September landed cost
If you are moving U.S.-origin goods from a U.S. port to Canada (or transshipping through the U.S. en route to Canada), or moving goods to the U.S. that include components subject to either U.S. or Canadian tariff rules, your landed cost now reflects:
- Base Trans-Pacific ocean freight (up ~3–5% early September)
- Pre–Golden Week space premium (carrier-specific; may add further surcharges)
- Panama Canal draft fees or alternate-route fuel costs (carrier-dependent)
- U.S. Section 301 / Section 122 tariffs (if applicable to China-origin goods entering U.S.)
- Canada counter-tariffs (if U.S.-origin goods entering Canada)
Pattern that fails: using August landed-cost worksheets with September 8 bookings.
Pattern that works:
| Cost layer | Where to find it | Reconfirm frequency |
|---|---|---|
| Ocean freight | Forwarder quote with as-of date | Per booking |
| Space premium | Carrier notice (often labeled "emergency" or "peak surcharge") | Weekly in Sep |
| Tariff rates | CBSA / CBP notices + customs broker | When policy updates |
| CUSMA interaction | Customs broker (CUSMA preferential does not exempt from Canada counter-tariff surtax) | Per shipment if U.S.→CA |
Booking discipline for September moves
Use this sequence when quoting or booking Trans-Pacific moves that touch Canada or the U.S. in September 2026:
1. Separate freight surge from duty change
Ask your forwarder:
- What is the base ocean freight for this lane as of today?
- Is there a Golden Week space premium or emergency surcharge on top?
- Does the quote include or exclude Panama Canal alternate-route fuel?
Do not accept one "all-in" number without the breakdown. If the rate moved 5% since last week, you need to know which layer changed.
2. Confirm HTS classification and counter-tariff applicability
For U.S.-origin goods moving to Canada:
- Which 10-digit HTS code applies?
- Is the product on Canada's September 8 counter-tariff list?
- What is the counter-tariff rate (15% / 25% / 50%)?
- Does CUSMA preferential treatment apply to the base duty (it does not exempt from the counter-tariff surtax)?
If your customs broker's worksheet still shows pre–September 8 rates, it is wrong.
3. Run two landed-cost scenarios: book now vs wait
Scenario A: Book by mid-September for pre–Golden Week departure
- Higher ocean freight (Sep 10 spot $7,352 SHA–LA; reconfirm before booking)
- Possible space premium
- Counter-tariff applies if U.S.→CA (15/25/50%)
- Cargo moves before October 1; less risk of post-holiday vessel bunching
Scenario B: Book post–Golden Week (mid-October sailings)
- Uncertain ocean freight (could ease if capacity returns; could tighten if backlog severe)
- Counter-tariff still applies if U.S.→CA
- Risk: post-holiday demand surge and blank-sailing recovery delays
Which scenario wins depends on:
- Whether your product faces a 50% counter-tariff (front-load to secure inventory before price increases propagate)
- Whether you have warehouse capacity to hold goods that arrive before retail windows open
- Whether cash flow allows higher per-container freight now vs uncertain rates later
There is no universal answer. Run both in a landed-cost calculator and decide based on your margin and storage cost.
4. Cube and weight discipline still matter
A 5% freight increase on a 40HC that ships at 85% cube utilization costs less per unit than a 40GP at 60% utilization with the same 5% increase. The tariff and rate surge do not erase the need to optimize packing.
Pre-book workflow:
- Model packing scenarios (20 / 40 / 40GP / 40HC) in a container calculator.
- Add the current spot rate (not last month's contract rate) to each equipment type.
- Apply the counter-tariff % to landed cost if the move is U.S.→CA.
- Compare total cost per unit across scenarios.
- Book the configuration that minimizes exposure to both the freight surge and the tariff stack.
For packing scenario comparison, see compare two packing scenarios before booking.
What CUSMA does and does not do
CUSMA (formerly NAFTA) provides preferential duty treatment for qualifying goods traded between Canada, the United States, and Mexico. That preferential treatment reduces or eliminates the base customs duty on eligible products.
Key point: CUSMA preferential treatment does NOT exempt goods from Canada's September 8 counter-tariff surtax.
Example landed-cost stack for U.S.-origin furniture entering Canada:
| Layer | Rate | Notes |
|---|---|---|
| CUSMA preferential base duty | 0% or reduced | Applies if goods qualify |
| Canada counter-tariff surtax | +50% | Applied on top of CUSMA rate |
If you assumed CUSMA would shield you from the counter-tariff, recalculate landed cost with the surtax included.
Source: Baker McKenzie notes that the surtax is additional to preferential CUSMA rates (Baker McKenzie, September 8, 2026).
Bottom line
Canada's September 8 counter-tariffs (15/25/50% on about C$27.6 billion of U.S. goods) and the Trans-Pacific rate climb before China's Golden Week (October 1–7) hit the same booking window. CUSMA preferential duty rates do not exempt goods from the counter-tariff surtax. Drewry’s September 10 prints show Shanghai–LA at $7,352 (+2%) and Shanghai–NY at $9,726 (+1%). Reconfirm before booking.
Before you book, separate the freight surge from the duty change, confirm HTS classification and counter-tariff applicability, and run two landed-cost scenarios (book now vs post–Golden Week). Then optimize cube and weight discipline so you minimize total exposure to both the rate increase and the tariff stack.
Use the Palletizr calculator to model equipment scenarios and compare landed cost per unit with the September 8 counter-tariff and current spot rates included — not the August worksheet you used last month.
