Shipping from China and Hong Kong to Thailand: customs, Laem Chabang and documents

Customs authority: The Customs Department of Thailand
Trade agreement: ASEAN China FTA, with Form E certificate of origin for duty relief
Import VAT: 7 percent, one of the lowest rates in the region
Product standards: TISI certification required for regulated product categories
Regional role: Land transport hub for Laos, Cambodia and mainland Southeast Asia
Main entry points: Laem Chabang by sea, Suvarnabhumi by air

The Form E certificate of origin does the same work here as in Vietnam: it delivers the ASEAN China preference, and Thai customs examines it carefully. Getting it issued correctly at origin is worth more than any freight negotiation on this lane.

Laem Chabang is the main deepwater port, about two hours from Bangkok, and it handles almost all containerised trade. Bangkok Port at Klong Toey still operates but with size and access limits, and it mainly serves cargo destined for the city itself.

Thailand also functions as a land transport hub for mainland Southeast Asia. Road connections to Laos, Cambodia and Malaysia are used routinely, and for cargo continuing to those markets a Thai entry point can make more sense than shipping to each country separately.

Where cargo lands

Main freight and distribution centres

Bangkok

The dominant market and the centre of distribution, customs brokerage and consumption.

Laem Chabang and the Eastern Seaboard

The port and the industrial corridor around it, including the automotive and petrochemical clusters.

Chonburi and Rayong

The Eastern Economic Corridor, with heavy manufacturing investment and correspondingly heavy import demand.

Chiang Mai

The northern region, served by road from Bangkok and with its own air gateway.

Sea freight

Ports of entry and what they mean for your cargo

Laem Chabang

The main deepwater port, handling almost all container traffic, with direct services from China and good connections to the industrial corridor.

Bangkok Port (Klong Toey)

River port inside the city with vessel size limits, useful for cargo destined to Bangkok itself.

Map Ta Phut

Industrial port serving the petrochemical complex, relevant for bulk and project cargo.

Songkhla

Southern port serving the south of the country and the Malaysian border region.

Transit from South China to Laem Chabang is short, with frequent services, so sea is realistic even for cargo with moderate urgency.

For cargo continuing to Laos or Cambodia, road from Thailand is well-established and often more practical than a separate sea movement to those countries.

Bangkok Port limits mean most commercial cargo goes through Laem Chabang regardless of the final destination, with a road leg into the city.

Air freight

Airports and when air is the right answer

Bangkok Suvarnabhumi (BKK)

The main air cargo gateway, with extensive direct capacity from Asia and full customs facilities.

Don Mueang (DMK)

Secondary Bangkok airport, handling some cargo and charter operations.

U-Tapao (UTP)

Serving the Eastern Economic Corridor, developing as a cargo and logistics point.

Air freight from China into Bangkok is frequent and well served, so urgent cargo has real options rather than theoretical ones.

For manufacturing in the Eastern Economic Corridor, the choice of arrival airport can save a significant road leg through Bangkok traffic.

Indicative transit times

How long the movement usually takes

Sea FCL, South China to Laem ChabangAround 4 to 9 days port to portFrequent direct services and short transits.
Sea LCL, South China to ThailandAround 10 to 18 days door to doorConsolidation adds most of the time.
Air freight, Hong Kong or South China to BangkokAround 2 to 5 days door to doorFrequent direct services including handling and clearance.
Onward road to Laos or CambodiaAround 2 to 5 daysWell established cross border routes, subject to border formalities.

These ranges are indicative and exist to help you plan. Real transit time depends on the service, the season, the routing and the clearance itself, and we confirm it per shipment rather than publish it as a promise.

Customs

How clearance into Thailand actually works

The competent authority is The Customs Department of Thailand.

The Form E certificate of origin delivers ASEAN China duty relief and is examined closely. As elsewhere in the region, discrepancies between the certificate and the commercial documents are the usual reason a preference is refused.

VAT is 7 percent, among the lowest in the region, and registered businesses recover it through their filings.

Duty depends on classification, and Thailand applies protective rates to some categories, particularly finished consumer goods that compete with domestic production.

TISI, the Thai Industrial Standards Institute, certifies regulated products, including electrical goods and construction materials. Where a mandatory standard applies, certification is required before import.

A foreign company without a Thai entity needs a local importer, since the declarant must be established in Thailand. Foreign ownership restrictions in some sectors also shape how the local structure can be set up.

Documentation

What you need to have ready

Commercial invoice

Value, terms and a precise description. It must agree with the Form E where a preference is claimed.

Packing list

Piece counts, weights and dimensions per package.

Bill of Lading or Air Waybill

The transport contract and the release instrument.

Form E certificate of origin

For ASEAN China FTA duty relief.

Import declaration

Filed electronically by the importer or its customs broker.

TISI certification

For products subject to a mandatory Thai industrial standard.

Import licence

Where the product category requires one.

Thai company registration and tax ID

Of the importer of record.

Controlled and restricted goods

What gets stopped, and why

TISI mandatory standards cover electrical goods, construction materials and other categories, and certification must be in place before import.
Food, cosmetics, medical devices and health products require FDA Thailand registration, which is a separate process from customs.
Some finished consumer goods face protective duty rates or licensing requirements.
Thai language labelling is required for goods sold to consumers.
Used machinery faces condition and age scrutiny in several categories.
Wood packaging must comply with ISPM 15.
