Peak Season Shipping Calendar: Thailand to USA (2026)
Thailand-to-USA transit is stable in the abstract and volatile in practice. Rates and space swing by 40–120% across the year for reasons that are entirely predictable. Book against the calendar and you keep the money.
Month-by-month planning view
| Period | Market condition | What to do |
|---|---|---|
| Jan (pre-CNY rush) | Very tight, rates climbing | Book 4 weeks ahead; cut-offs move earlier |
| Late Jan–mid Feb (Chinese New Year) | Space opens, Asia output drops | Cheapest window; factories in Thailand run but Chinese inputs stall |
| Mar–Apr | Soft, competitive | Best time to negotiate annual contract rates |
| Mid-Apr (Songkran) | Thai factories closed 3–5 days | Add one week to production, not transit |
| May–Jun | Firming | Book Q3 holiday-season goods now |
| Jul–Sep (peak season) | Tight, GRI + PSS applied | Book 3–5 weeks ahead; expect rollovers |
| Oct | Peak fades after Golden Week | Ship replenishment |
| Nov–Dec | Moderate, pre-CNY builds | Lock Q1 volume, watch Dec cut-offs |
The surcharges you will actually see
- GRI (General Rate Increase): carrier-announced, usually the 1st or 15th, USD 200–600 per 40ft during peak.
- PSS (Peak Season Surcharge): typically June–October, USD 150–500 per container.
- Bunker adjustment (BAF/LSS): fuel-linked, moves monthly.
- Congestion / port fees: episodic, US West Coast and Gulf.
- Chassis and detention/demurrage: the ones that actually surprise importers — negotiate free days upfront (aim for 5 at destination).
Realistic transit from Thai ports
| Route | Transit (days) | Notes |
|---|---|---|
| Laem Chabang → Los Angeles/Long Beach | 21–28 | Usually via transshipment at Singapore or Port Klang |
| Laem Chabang → Seattle/Tacoma | 24–30 | Fewer direct strings |
| Laem Chabang → New York/Savannah | 32–42 | Suez or Panama routing dependent |
| Laem Chabang → Houston | 35–45 | Panama transit variability |
Add 5–10 days of buffer during peak. Transshipment at Singapore is where most Thai cargo loses time.
Holidays that move your ship date
- Songkran (mid-April): 3–5 day factory shutdown, longer for upcountry plants as staff travel.
- Chinese New Year (late Jan–Feb 2026): Thai plants stay open, but Chinese-sourced components, resins, and electronics stall for 2–3 weeks. This is the most common cause of a missed Thai ship date.
- Thai royal and Buddhist holidays: single days scattered across May, July, August, October and December — each shifts loading plans slightly.
- US Golden Week impact: Asia-wide space competition in early October.

A booking discipline that works
- Work backwards from your in-store or in-FBA date, then add: 10 days buffer + transit + 7 days port/loading + production lead time.
- Confirm the vessel booking before releasing the final production payment schedule.
- Split large programs across two sailings during peak to survive a rollover.
- Get quotes valid to a named vessel, not "subject to space".
- Track blank sailing announcements — carriers cancel capacity fastest in March and November.
TUSKO books space against your delivery date and holds the factory to the loading window, so the two halves of the schedule are managed by one party.
FAQ
When is the cheapest time to ship from Thailand to the USA?
Typically late February through April, after Chinese New Year and before peak season surcharges begin. Rates in that window can run 30–50% below July–September levels.
How far ahead should I book during peak season?
Three to five weeks for a confirmed slot from July to September, and expect at least one rollover on tight West Coast strings.
Does Chinese New Year affect Thai factories?
Yes, indirectly but significantly. Thai plants keep working, but Chinese-supplied components and raw materials stop for two to three weeks, which is a frequent cause of delayed loading.
What is a blank sailing and how do I protect against it?
A blank sailing is a cancelled vessel call used by carriers to manage capacity. Protect yourself by splitting shipments across sailings and getting bookings tied to a named vessel.
How long does Laem Chabang to Los Angeles take?
Usually 21–28 days port to port, most often with a transshipment at Singapore or Port Klang. Add buffer in peak season.
Should I ship LCL to avoid peak season rates?
LCL rates also rise in peak and per-CBM costs are higher. If you are above roughly 15 CBM, a 20ft FCL is normally cheaper and faster through the port.
