Ranong Port: Thailand's Andaman Sea Gateway Explained

Thailand has two coastlines, but almost all of its container trade leaves from one of them. Laem Chabang, on the Gulf of Thailand, handles the bulk of the country's ocean containers, and cargo heading west to India, the Middle East, Africa or Europe usually sails south around the Malay Peninsula and through the Strait of Malacca, often changing ships at a regional hub. On the other side of the country, facing the Andaman Sea, sits Ranong Port. It is the Port Authority of Thailand's (PAT) Andaman gateway, and its whole argument is geography: a ship leaving Ranong is already in the Indian Ocean basin.

That argument has been made for decades, and Ranong has found real uses, especially for cargo linked to Myanmar and to offshore energy work in Myanmar waters. It has not replaced Laem Chabang for mainstream container trade, and it is important to understand why before you plan around it. This guide explains where the port is, what it is built to handle, who uses it, how cargo gets there, how it compares with Laem Chabang and Songkhla, and how customs and the Myanmar border fit in. It avoids quoting rates, transit times or service schedules, because those change; where a fact comes from PAT's own description of the port, that is stated.

Where is Ranong Port and who runs it?

Ranong Port is on the east bank of the mouth of the Kraburi River, in Pak Nam subdistrict of Mueang Ranong district, on Thailand's Andaman coast, and it is operated by the Port Authority of Thailand.

The Kraburi River forms part of the border between Thailand and Myanmar, so the port looks across the estuary towards Myanmar territory, with Kawthaung, Myanmar's southernmost town, nearby. That proximity shapes everything about the port's trade.

According to PAT's history of the site, the port was originally built and run by another government agency and was transferred to PAT under a Cabinet resolution in March 2003, with PAT taking responsibility for developing it as Thailand's Andaman gateway. Since then PAT has expanded it, adding container handling and support facilities.

The port sits close to Ranong town, which is a provincial centre with fishing, tourism and cross-border trade, and close to the land and water crossings into Kawthaung. It is a long way from Thailand's main industrial areas, which is the core trade-off discussed below. For a shipper, the useful mental model is a regional port at the north end of the Andaman coast, facing Myanmar and the Indian Ocean, run by the same authority that operates Laem Chabang and Bangkok Port, but on a much smaller scale.

What can Ranong Port handle?

Ranong is built for small and medium vessels: PAT describes a multipurpose berth for small craft and a dedicated container berth for vessels up to about 12,000 deadweight tonnes, plus yard, warehouse and support facilities.

PAT lists two main berth types. The first is a multipurpose berth for vessels up to about 500 gross tonnes, the kind of small craft used for coastal trade and offshore support. The second is a container berth designed for vessels up to about 12,000 deadweight tonnes, which PAT says opened in July 2006. For context, that is a feeder-size ship, far smaller than the mainline container vessels that call at Laem Chabang.

Around the berths, PAT lists a warehouse, a container yard, tank storage for liquids in a bonded area, reefer plugs for refrigerated containers, a mobile harbour crane and a one-stop service building that brings together the agencies a shipper deals with. That mix supports general cargo, containers, liquid cargo and the supply runs that offshore operations need.

The access channel matters as much as the berths. PAT describes the channel into the port as dredged to about 8 metres at the lowest low water level. In practical terms, that is enough for small and medium vessels and feeders but not for large ocean-going ships, and any vessel planned for the port needs its draft checked against the channel and tide.

So the honest answer to what Ranong can handle is: general cargo, containers on feeder-size ships, liquids in bonded tanks, reefer boxes, and offshore supply work, all on a regional scale. It is not a port where a large mainline container ship will call, and it is not designed to handle the volumes of Laem Chabang.

Who actually uses Ranong Port?

The main users have been offshore oil and gas operators and their support companies working in Myanmar waters, along with regional cargo for southern Myanmar and local Andaman trade.

PAT's own description of the port's users is candid. It notes that the main customers have included petroleum concession holders and their contractors operating in the Gulf of Mottama area off Myanmar, who use Ranong as a supply base. Offshore projects need a steady stream of pipe, equipment, drilling materials, fuel, water and provisions, and Ranong is the nearest Thai port with the facilities, bonded storage and customs set-up to support that work.

PAT also records that a container service between Ranong and Yangon operated in 2015 and later stopped because there was not enough return cargo from Myanmar. That is a useful lesson for any shipper. A port can have the berths and the cranes, but a scheduled service only survives if there is cargo in both directions. When a carrier cannot fill the ship on the way back, the service ends, and any shipper who built a supply chain around it has to re-route.

Other users include coastal traders moving consumer goods, construction materials and food into southern Myanmar, fishing-related trade, and project shipments where the Andaman location is genuinely useful. Some of this moves through the port; some of it moves through the smaller piers and border crossings around Ranong and Kawthaung, which work under their own rules.

What Ranong does not have is a large base of Thai manufacturers on its doorstep generating steady container exports. That is the structural reason it remains a niche port.

How does cargo get to Ranong Port?

Most cargo reaches Ranong by road along Highway 4 from Bangkok and the south, turning west towards Ranong in Chumphon province; PAT also describes a rail option to Saphli station in Chumphon, which has a container yard, with trucks covering the last leg.

PAT describes the road route as Highway 4, Phetkasem Road, south from Bangkok to the Pathomporn junction in Chumphon, then west on road 4010 towards Ranong and on to the port. The crossing from the Gulf side to the Andaman side runs through hilly country, which matters for heavy loads, and for cargo from the Eastern Seaboard or central Thailand the road leg is long. Shippers should treat the inland haul as a major part of total cost and time, not an afterthought.

For rail, PAT points to Saphli station in Pathio district, Chumphon, as a railhead with a container yard. Cargo can move by rail from central Thailand to Saphli and then by truck across to Ranong. Whether this is practical for a given shipment depends on current rail services, slot availability and the extra handling at the transfer, so confirm it with the State Railway of Thailand or your forwarder before planning around it.

For cargo from southern Thailand, such as seafood, rubber products or palm oil from provinces closer to the Andaman side, the road distance is much shorter, and Ranong's location looks more attractive. That is one reason regional cargo uses the port even though national volumes go elsewhere.

The inland leg is where the Andaman shortcut can be gained or lost. A ship from Ranong avoids a long sea passage around the peninsula, but the cargo first has to cross the peninsula by land. Compare the whole chain, factory to destination, before deciding.

How does Ranong compare with Laem Chabang and Songkhla?

Laem Chabang is Thailand's main container port with frequent services to every major trade lane; Songkhla serves the lower south on the Gulf side; Ranong is the Andaman-side option for the right cargo, mainly Myanmar-linked and offshore work.

Laem Chabang, covered in our Laem Chabang port guide, is where the mainline and feeder container services are. For a full container to India, the Gulf states, East Africa or Europe, it is normally the default: there are frequent sailings, competitive capacity, and either direct services or connections through a transshipment hub. The ship sails the long way round, but it sails often, and that frequency usually matters more to the shipper than the distance. Our article on direct services versus transshipment explains how to judge that trade-off.

Songkhla, covered in our Songkhla port guide, is the Gulf-side port for the lower south, with feeder container services that connect to regional hubs. Exporters of rubber, seafood and other southern products often weigh Songkhla against trucking to Laem Chabang or across the Malaysian border to Penang or Port Klang.

Ranong sits on the opposite coast and serves a narrower set of needs. It makes the most sense when:

• The cargo is going to Myanmar, especially southern Myanmar or offshore sites in Myanmar waters.
• The cargo supports offshore energy or marine work in the Andaman Sea.
• The origin is in the upper south close to the Andaman side, so the inland haul is short.
• A specific vessel, charter or service is confirmed to call Ranong for the voyage you need.

For mainstream full-container exports from central or eastern Thailand to South Asia, the Middle East or Europe, the starting assumption should still be Laem Chabang, unless a forwarder can show you a current Ranong service that beats it on total time, reliability and cost for your specific cargo.

Does Ranong really avoid the Strait of Malacca?

Geographically yes: a ship leaving Ranong is already west of the Malay Peninsula, so PAT presents the port as a way to reach South Asia, the Middle East, Africa and Europe without sailing via Singapore and the Strait of Malacca. Commercially, the benefit only exists if a suitable service calls.

PAT's case for Ranong is straightforward. A vessel from Laem Chabang to India, for example, must sail south around the Malay Peninsula and up through the Strait of Malacca, often stopping at Singapore or another hub to transfer containers to a larger ship. A vessel leaving Ranong is already in the Andaman Sea, so the sea distance to ports around the Bay of Bengal is much shorter, and PAT also positions Ranong as a link to BIMSTEC countries around the bay.

The catch is that container shipping runs on networks, not single voyages. Most carriers concentrate their westbound services where the cargo is, which is the Gulf of Thailand side and the big regional hubs. A shorter distance from Ranong does not help a shipper if no service calls Ranong in the week they need it, or if the only option is a small feeder that itself has to connect somewhere else.

The Ranong–Yangon service that ran in 2015 and then stopped is the clearest example. The geography was right, but without enough return cargo the carrier could not sustain it.

So the practical question is never whether Ranong is closer. It is whether there is a vessel, a service or a charter calling Ranong now that fits your cargo, your volume and your dates. If there is, the shorter sea leg can be real. If there is not, the geographic advantage stays theoretical.

How do customs and the Myanmar border work around Ranong?

Cargo through Ranong Port clears Thai customs like any other port, through an electronic declaration filed by the exporter, importer or a licensed broker; cargo crossing to Kawthaung by land or small boat uses border procedures that are separate from the port.

The Thai Customs Department operates at Ranong. Exports and imports through the port need a customs declaration with the correct HS code, value, origin and any permits the goods require. PAT's one-stop service building is meant to bring the relevant agencies into one place, which helps for shipments that need customs, immigration for crew, and other agency checks at the same time. Bonded storage for liquids allows certain goods, such as fuel for offshore operations, to be held under customs control.

Ranong is also a border province. Across the Kraburi estuary is Kawthaung, and there is trade between the two towns by small vessels as well as through formal crossing points. That trade works under border trade rules, with its own documents and checkpoints, and the arrangements, opening status and permitted goods can change with conditions in Myanmar and with Thai policy. If you plan to use a Ranong–Kawthaung crossing rather than the port, confirm the current status, the permitted cargo and the procedures with Ranong Customs and a local broker before you move.

On the Myanmar side, imports need Myanmar customs clearance, import licences where required, and payment arrangements that work under current Myanmar rules. Those rules have changed frequently in recent years, so the buyer and their broker in Myanmar should confirm what is needed for each shipment. Our guides to shipping from Thailand to Myanmar and to the Thailand–Myanmar road freight checklist cover the wider set of routes, including the main land crossing at Mae Sot.

What should exporters watch out for at Ranong?

The main risks are assuming a service exists when it does not, underestimating the inland haul, sending a vessel whose draft does not fit, and treating border-trade rules as if they were port rules.

Most problems with Ranong come from expectations formed by its location rather than its current operations.

• Assumed services. Port websites and news articles describe Ranong's potential and past services. Neither is proof that a service calls now. Get a written booking confirmation from a carrier or charterer for your sailing.
• Inland cost and time. The truck or rail leg from central or eastern Thailand is long and crosses hilly terrain. Build it into the quote and the timeline from the start.
• Vessel fit. Ranong is built for small and medium vessels. A charter or project ship needs its length, draft and cargo gear checked against the channel and berth before it is fixed.
• Equipment for heavy lifts. Heavy or out-of-gauge pieces need confirmation that the port's crane and yard can handle them, or that the vessel has its own gear.
• Return cargo and container supply. If you need empty containers at Ranong, confirm that the carrier will position them there. On thin routes, empties may have to be trucked in.
• Border-trade confusion. Small-boat and land trade with Kawthaung works under border rules that differ from port procedures. Do not assume a document or permit valid at one is valid at the other.
• Myanmar-side changes. Import licensing, payment and security conditions in Myanmar can shift quickly. Confirm with the buyer before every shipment, not just the first.
• Insurance. Make sure the policy covers the inland leg, any coastal or feeder voyage, and storage at the port.

When is Ranong the right choice?

Ranong is the right choice when your cargo is going to Myanmar or supporting work in the Andaman Sea, when your origin is close to the Andaman side, or when a confirmed vessel or service gives a real advantage over routing through the Gulf of Thailand.

Put simply, choose Ranong for the cargo and routes it was built and used for, and verify everything else. A useful way to decide is to start from the destination and the cargo, then test Ranong against the alternatives.

If the destination is an offshore site or a coastal town in southern Myanmar, Ranong is often the natural base, and the main questions are vessel availability, permits and Myanmar-side clearance. If the destination is Yangon, compare a Ranong option, if one exists, with sea freight via Laem Chabang and with road freight through Mae Sot; the answer will depend on volume, timing and conditions in Myanmar. If the destination is India, Bangladesh, Sri Lanka, the Middle East or Europe, start from Laem Chabang and ask your forwarder whether any Andaman-side option would genuinely beat it for your shipment.

The answer can change. New services, changes in Myanmar, port development and changes in carriers' networks can all shift the picture, so it is worth checking again when you plan a new lane rather than relying on what was true a year ago.

How do you plan a shipment through Ranong?

Confirm the vessel or service first, then plan the inland leg, customs at Ranong and destination clearance around it, and compare the full chain with the Laem Chabang alternative.

A practical sequence:

• Define the cargo: HS code, weight, dimensions, packing, value, and whether it is dangerous, perishable or out of gauge.
• Ask for a written confirmation of a vessel, service or charter calling Ranong for your dates, with the vessel's size and draft.
• Get a parallel quote via Laem Chabang, including transshipment, so you can compare total time, reliability and cost.
• Book the inland leg by road or rail to Ranong and check access for heavy or oversized pieces.
• Appoint a customs broker with staff at Ranong and prepare the export declaration, invoice, packing list and any permits.
• Arrange destination clearance with the buyer and their broker, including import licences and payment terms that work under current rules.
• Confirm insurance covers the whole route, including inland, coastal and storage legs.
• After the shipment, record what worked and what did not, so the next decision is based on your own data.

Thai Global Freight (TGF) can quote Andaman and Gulf routings side by side, coordinate the inland haul and documents, and hand off customs work to a broker at the relevant port, so you choose on the full picture.
