Supply Chain Cadence Weekly (5 October 2026): Shanghai to Los Angeles Lithium Cells, Rates Peaking but Duties Now Dominate Cost

Executive Summary

Ocean freight on the Shanghai to Los Angeles lane has stopped rising but remains very expensive. Drewry's index held at US$7,835 per 40ft container on 1 October 2026, unchanged from the week before. Xeneta's chief analyst says the market has reached its post-Hormuz crisis peak but will not collapse. For lithium cells moving from China to Los Angeles, the bigger swing factor this week is tariffs: USTR's forced-labor Section 301 action sets 12.5% for investigated economies without a lower rate; a battery vendor's blog (single source) says it applies to Chinese goods entered from 24 July 2026 unless exempt, on top of older duties. Dangerous-goods rules for cells are a further compliance item.

Edition scope: lane = Shanghai to Los Angeles; product = lithium cells (lithium-ion, UN 3480 / 3481 context); cadence = weekly. No named suppliers were supplied, so no supplier or sanctions screening was run this edition.

Lane rates: Shanghai to Los Angeles has plateaued at an elevated level

Benchmark rate: Drewry assessed Shanghai to Los Angeles flat at US$7,835 per 40ft on 1 October 2026. Shanghai to New York rose 1% to US$10,428 in the same assessment. (The cited page is a trade-desk summary of Drewry's release; Drewry's own page was not opened directly.)

Second benchmark: Xeneta's market average for Far East to US West Coast was US$8,346 per FEU on 1 October, up 1.4% on the week, and up 344% versus 28 February 2026, before the Hormuz crisis. The two indexes differ in method and port coverage, so the gap between US$7,835 and US$8,346 is not a contradiction.

Momentum: The NYSHEX Freight Index (NYFI) Asia to US West Coast reading rose 1.89% to 7,557.37, versus a 4.82% rise in the prior reading. The SCFI fell 0.66% to 3,662.30.

Outlook: Xeneta sees rates into the US West Coast around US$4,500 to 5,500 in three months, a "sizeable correction, but not a collapse", and warns that new disruption could change this. Drewry expects Transpacific rates to ease in the next reading while Chinese factories are shut for Golden Week, and carriers had 10 blank sailings announced for the following week, down from 13.

KEY TAKEAWAY: Budget Shanghai to Los Angeles freight near current levels for October bookings; Xeneta expects a decline over the next three months, not a collapse.

Los Angeles port: busy but not congested, with some dwell-time warning signs

A 2 October trade report says the Port of Los Angeles is handling sustained volumes without vessel queuing, unlike the 2021 to 2022 crisis. The same site lists a 30 September piece on rising container dwell times at Los Angeles and Long Beach, which I did not open. The report itself cautions that fluidity is "a condition, not a guarantee". A Tradlinx post on rising LA/LB delays was blocked and not read, so treat delay claims as unverified. Asian-side congestion is a separate risk: Xeneta attributes part of the rate turn to easing Asian port congestion as typhoon season winds down, and Golden Week lowers early-October exports.

Tariffs: three duty layers can stack on Chinese lithium cells

The most important policy fact this week is the forced-labor Section 301 action. USTR announced on 23 July 2026 that it is imposing tariffs on 60 economies, with 12.5% for all other investigated economies not given a lower rate. The USTR release lists product exemptions in general categories; it does not name China or batteries. China is not in the lower-rate lists on the USTR page, which is consistent with the 12.5% rate, but the China-specific application and the 24 July effective date come from a battery vendor's blog, not USTR.

That vendor blog (Large Power, 18 August 2026) says covered Chinese non-EV lithium-ion batteries carry a 25% legacy Section 301 duty, a 3.4% normal HTSUS duty under 8507.60 for its illustrative case, and the new 12.5%, totalling 40.9% before other duties and fees. This is a single-source, commercial claim from a Chinese battery maker and I did not verify it against the Federal Register or HTS. Cells versus packs, EV versus non-EV use, and exemptions can change the result. Do not use 40.9% as a purchase-order assumption without a broker's confirmation of the 10-digit HTS code and Chapter 99 treatment.

On a US$100,000 customs value, the vendor's illustrative stack is US$40,900 in duty, more than five times the Drewry freight cost of one container. At current rates, duty rather than freight is the main landed-cost driver for this product. The vendor also notes that paying the tariff does not protect against UFLPA or Section 307 detention, so cell, graphite and lithium-compound traceability still matters.

Dangerous-goods handling: updated carrier guidance exists, details unread

The Cargo Integrity Group (CINS) published updated guidelines for shipping lithium-ion cells and batteries (UN 3480 and 3481) in cargo transport units on 27 April 2026, aimed at carriers and operators. I could only read the landing page, not the PDF, so I cannot state specific requirements such as state-of-charge limits. A separate CINS paper on IMDG Special Provision 188 is listed in the same newsroom. My inference, not from the source: confirm each carrier's current lithium acceptance policy before booking.

What to do this week

Freight: Anchor October Shanghai to Los Angeles budgets to the current benchmarks (Drewry US$7,835 per 40ft; Xeneta US$8,346 per FEU; different methods), and ask for post-Golden Week blank-sailing lists.
Duty: Obtain a written HTS and Chapter 99 determination for each cell or pack SKU; model landed cost with and without the 12.5% layer.
Compliance: Request carrier DG acceptance and the latest CINS-aligned packing requirements before cargo-ready date.
Watch next week: Post-Golden Week Drewry and Xeneta prints, carrier General Rate Increase announcements, and any USTR exemption changes.

Evidence gaps

No Drewry or Federal Register primary page for the China 12.5% rate was read directly.
No source for Los Angeles throughput volumes (TEU) this week was opened.
No supplier names were provided, so sanctions, UFLPA entity and financial screening were not performed.
