The Deep-Water Port Map That Decides Your Vietnam Lead Time

In our experience qualifying suppliers across six product categories, the buyers who plan lead time backward from the right port avoid the most common surprise on a first Vietnam order: a quote built on a direct sailing that never existed for that factory’s region. Vietnam’s port build-out is one of the strongest stories in Asian logistics right now. Three of its port areas rank among the world’s most efficient, a new mega-port is under construction near Ho Chi Minh City, and the northern deep-water gateway just added berths that take the largest ships afloat. The task for a buyer is to match the factory to the port, then read the routing that follows.

Why the port, not the factory, sets your clock

A factory quote usually ends at the FOB line, the moment your goods are loaded on the vessel at the port of export. Everything before that line, including the truck or barge leg from the factory to the port, is baked into where the supplier sits. A garment maker in Ho Chi Minh City and an electronics assembler in Bac Ninh both make “Vietnamese goods,” but they load at different ports, catch different services, and reach your warehouse on different timelines.

The variable that matters most is whether the port your supplier uses has a direct deep-sea call to your market. A direct call means your container boards a mother vessel bound straight for the US or Europe. No direct call means a feeder ship carries your box to a transshipment hub first, then transfers it, which adds handling, cost, and typically several days. For a US-bound shipment, transit runs about 18 to 22 days to the West Coast and 28 to 35 days to the East Coast via the Suez Canal from a direct Vietnamese sailing. Add a feeder leg and that clock starts later than your quote assumes.

The southern cluster: Cai Mep-Thi Vai

Cai Mep-Thi Vai is Vietnam’s deep-water gateway for the south, sitting in Ba Ria-Vung Tau province about 50 kilometres southeast of Ho Chi Minh City by river. Its channel was deepened to 18 metres, which makes it the only Vietnamese port complex that can take fully loaded ultra-large container ships. Terminals here handle vessels up to 24,188 TEU and 214,121 DWT without draft restrictions, the class that sails the main US and Europe trades.

That depth is why the direct services live here. Carriers including MSC, ONE, COSCO, OOCL, and Evergreen run direct routes from the cluster to the US, Europe, and Africa. Volume backs the infrastructure: mother-vessel throughput at Cai Mep-Thi Vai rose more than 18 percent in the first ten months of 2025, and the World Bank ranked the Cai Mep area 30th in its Container Port Performance Index 2024 after moving over 7 million TEU that year.

For a buyer, the read is simple. If your supplier sits in the southern industrial belt around Ho Chi Minh City, Binh Duong, and Dong Nai, Cai Mep-Thi Vai is your deep-sea port, and a direct sailing to your market is on the table. That is the shortest lead-time path Vietnam offers on the southern side.

The southern workhorse: Cat Lai

Cat Lai in Ho Chi Minh City is Vietnam’s largest and busiest container terminal, moving well over 8 million TEU a year. It is close to the southern factories and fast to truck to, which is why so much cargo starts there. The constraint is geography: Cat Lai sits on the Saigon River with a water depth around 12 metres, too shallow for the largest mother vessels. In practice it works as a high-volume feeder and domestic hub. Boxes for the main deep-sea trades are commonly moved by barge to Cai Mep, a 6 to 8 hour barge run, to catch the direct services there.

Cat Lai is not a weakness in the map. It is a fast, dense collection point that pairs with Cai Mep’s depth. But if your quote loads at Cat Lai and your goods are US or Europe bound, price and time in that barge-plus-transfer step rather than assuming a direct sailing from the river terminal.

The northern gateway: Lach Huyen

Lach Huyen is the deep-water port of Hai Phong and the export gateway for the north. This is the port that matters if your supplier is in the Hanoi and Bac Ninh corridor, home to the electronics clusters that build for Samsung, Canon, and a long list of component makers. Hai Phong sits about 100 kilometres east of Hanoi, a short truck leg from those factories.

Lach Huyen was built to solve the same problem Cai Mep solved in the south: give the region a berth deep enough for the biggest ships. The Hateco Hai Phong International Container Terminal opened with a 900 metre wharf and water depth of 16.8 to 18.4 metres, taking vessels up to 18,000 TEU. Its newer berths opened direct routes to Europe and the Americas, including sailings straight to the US West and East Coasts. Hai Phong moved around 7.1 million TEU in 2024 and ranked 29th in the World Bank’s Container Port Performance Index 2024, just ahead of Cai Mep.

For a buyer sourcing electronics, footwear, or garments from the north, Lach Huyen gives you a direct deep-sea call without routing cargo the length of the country to a southern port. That is the point of the deep-water build-out: each manufacturing region now has its own gateway to the world.

The next chapter: Can Gio

The map is still being drawn. Near Ho Chi Minh City, construction is underway on the Can Gio International Transshipment Port, a project the Prime Minister approved on 16 January 2025. It is a roughly 4.9 billion US dollar build, with MSC’s terminal arm holding 49 percent, designed to handle 4.8 million TEU a year by 2030 and up to 16.9 million TEU by 2047, with berths for ships up to 250,000 DWT.

Can Gio is aimed at international transshipment, cargo that changes ships in Vietnam rather than only entering or leaving it. For buyers, the near-term signal is confidence rather than a service to book today. It tells you the southern gateway is being expanded with a major carrier’s own capital, which points to more direct capacity and steadier space in the years your sourcing program will run.

The port-to-region map

What we tell buyers to do

Three moves. First, confirm the port of loading in the FOB quote and whether the booked service is a direct mother-vessel call or a transshipment, before you compare prices. Second, match the port to the factory’s region using the table above, and treat any southern quote that loads at Cat Lai as a barge-plus-transfer path unless the supplier shows a direct Cai Mep booking. Third, model landed cost on the routing you will actually get, not the one the quote implies.

You can pressure-test the routing while you still have leverage at the quotation stage. Filter for factories in the region that matches your target port in the verified supplier directory, and put the transit and port fees into the landed-cost calculator so the number your CFO sees reflects the real sailing. The port is not a detail you sort out after you pick a supplier. It is part of picking the supplier.

Frequently Asked Questions

Q: Which Vietnamese ports have direct deep-sea services to the US and Europe?

Cai Mep-Thi Vai in the south and Lach Huyen in Hai Phong in the north both run direct mother-vessel services to the US and Europe. They are the two ports deep enough to take the largest container ships, so they carry the direct trades. Most other Vietnamese terminals feed cargo to these two or to regional transshipment hubs.

Q: Which port should my Vietnamese supplier use?

It depends on the factory’s region. Suppliers in the Ho Chi Minh City belt (including Binh Duong and Dong Nai) load through the south and reach deep-sea services at Cai Mep-Thi Vai. Suppliers in the Hanoi and Bac Ninh corridor load through Lach Huyen in Hai Phong. Matching the port to the region gives you the shortest transit and avoids routing cargo across the country.

Q: Why does Cat Lai handle so much volume if it cannot take big ships?

Cat Lai is Vietnam’s busiest terminal because it is close to the dense southern factory base and quick to truck to. Its river location limits depth to about 12 metres, so it works as a high-volume feeder. Boxes bound for the main US and Europe trades are typically barged 6 to 8 hours to Cai Mep to board a mother vessel there.

Q: How long does shipping from Vietnam to the US take?

From a direct Vietnamese sailing, transit runs roughly 18 to 22 days to the US West Coast and 28 to 35 days to the East Coast via the Suez Canal. A feeder leg to a transshipment hub adds handling and usually several days, so a direct call from Cai Mep-Thi Vai or Lach Huyen is the faster path when your supplier’s region supports it.

Q: What is the Can Gio port and does it affect my sourcing now?

Can Gio is a new international transshipment port near Ho Chi Minh City, approved in January 2025 with MSC as a major investor, targeting 4.8 million TEU a year by 2030. It is not a service you can book today. For now it signals that southern deep-sea capacity is expanding, which supports steadier space and more direct routing over the life of a sourcing program.
