South Summit is a Bangkok-based specialized law firm, established in 2014, operating at the intersection of international trade, business and contract law, human rights, international NGO advisory, and media and entertainment law. The firm advises Thai industries, exporters, commercial enterprises, creative sector clients, international organizations, and individuals engaged in transnational litigation, each navigating complex and multi-jurisdictional legal environments.

The firm's practice is led by attorneys with complementary expertise spanning transnational litigation and trade law, media and entertainment, and human rights advocacy. This multidisciplinary strength is unified by a commitment to client-centered, purpose-driven legal representation, supported by a broader team of legal professionals across all core practice areas.

The firm is led by its Managing Director, Dornnapha Sukkree, who also serves as Co-founder and Executive Director of MAST Human, a nonprofit social enterprise dedicated to combating human trafficking and forced criminality through the application of legal expertise and technology. This dual role reflects a broader institutional commitment to ethical leadership and human-centered policy, which underpins the firm's approach to every mandate.

International Trade

Section 301 and What It Means for Thai Exporters

Section 301 of the U.S. Trade Act of 1974 gives the U.S. government authority to impose tariffs and trade restrictions on countries it determines are engaging in unfair trade practices. For Thai businesses exporting to the United States, understanding how this mechanism works — and when it applies — is increasingly essential.

How Section 301 Works

The U.S. Trade Representative (USTR) initiates a Section 301 investigation either on its own initiative or in response to a petition. If the USTR determines that a foreign government's acts, policies, or practices are unreasonable, discriminatory, or burden U.S. commerce, it can recommend retaliatory action — most commonly in the form of additional tariffs on imports from that country.

The China Tariffs and Spillover Effects on Thailand

The most significant recent application of Section 301 has been the tariffs imposed on Chinese goods beginning in 2018. These tariffs — covering hundreds of billions of dollars in imports — have had a direct effect on Thailand. As companies restructured supply chains to avoid China-origin tariffs, Thailand became a key alternative manufacturing hub. This brought investment and orders — but also increased scrutiny. U.S. Customs and Border Protection (CBP) has intensified efforts to identify tariff circumvention, where goods are routed through third countries to avoid applicable duties.

What This Means Practically for Thai Businesses

Thai exporters in sectors including electronics, solar panels, rubber, seafood, and steel have faced CBP inquiries into the origin of their goods. A business that sources significant inputs from China and processes them in Thailand may be found to have engaged in circumvention if the processing does not constitute substantial transformation under U.S. rules of origin.

The consequences of a circumvention finding are serious: retroactive duty liability, exclusion from the U.S. market, and in some cases, referral for criminal investigation. Thai businesses need to ensure their supply chain documentation, production records, and origin determinations are robust before a CBP inquiry arrives — not after.

How South Summit Can Help

South Summit advises Thai exporters on rules of origin compliance, supply chain structuring, and response strategies when CBP inquiries or Section 301 investigations arise. Working with our U.S. firm partners, we provide coordinated Bangkok–Washington counsel across the full lifecycle of a trade enforcement matter.

Forced Labor Compliance

The UFLPA: How U.S. Forced Labor Import Rules Affect Thai Supply Chains

The Uyghur Forced Labor Prevention Act (UFLPA), signed into U.S. law in 2021 and enforced from June 2022, creates a rebuttable presumption that goods made — in whole or in part — with forced labor from China's Xinjiang region are prohibited from entering the United States.

The Rebuttable Presumption Standard

Under the UFLPA, U.S. Customs and Border Protection (CBP) presumes that any goods mined, produced, or manufactured in Xinjiang — or by entities on the UFLPA Entity List — were made with forced labor. The burden falls entirely on the importer to rebut this presumption with clear and convincing evidence. This is a high standard, and many shipments have been detained or excluded because importers could not meet it.

Why This Matters for Thai Businesses

Thailand is deeply integrated into global supply chains that source materials, components, and inputs from China — including from Xinjiang. Sectors particularly exposed include textiles and apparel (cotton), electronics and semiconductors (polysilicon), rubber and chemical products, and agricultural inputs. A Thai manufacturer that unknowingly incorporates a Xinjiang-origin component into its product may find its entire shipment detained at a U.S. port of entry.

What Compliance Requires

Effective UFLPA compliance requires supply chain mapping to the raw material level, supplier due diligence and audit programmes, documentation capable of proving input origin, and — where Xinjiang-origin inputs are identified — sourcing alternatives. The USTR and CBP have made clear that lack of awareness is not a defence. Thai exporters to the U.S. market need to know what is in their supply chains.

How South Summit Can Help

South Summit works with Thai exporters to conduct supply chain due diligence, build the compliance record required under the UFLPA, and respond to CBP detentions or requests for information. In coordination with our U.S. firm partners, we provide end-to-end support from Bangkok to Washington.

Public Procurement & PPP

Thailand's PPP Framework: What Private Investors and Project Developers Need to Know

Thailand's Public-Private Partnership Act B.E. 2562 (2019) established a modernised framework for private sector participation in public infrastructure projects. For foreign investors, developers, and lenders entering the Thai market, understanding the PPP regime is foundational to structuring transactions correctly from the outset.

What the PPP Act Covers

The PPP Act applies to projects where a state agency partners with a private entity for the design, construction, financing, operation, or maintenance of infrastructure or public services. Projects meeting a threshold of THB 5,000 million or more in investment value are subject to the full PPP process, including a Joint Committee review, Cabinet approval, and procurement under PPP-specific rules.

Key Structural Features

Thai PPP transactions are typically structured as concession agreements under which a private party is granted the right to build and operate infrastructure — such as toll roads, mass transit systems, airports, utilities, or healthcare facilities — in exchange for revenue rights over a defined period. The state retains ownership of the underlying asset.

Critical negotiation points include revenue-sharing mechanisms, risk allocation between public and private parties, force majeure and change-in-law provisions, step-in rights for lenders, and termination and compensation regimes. Getting these right at the structuring stage is essential — renegotiation after financial close is difficult and costly.

Public Procurement Outside the PPP Threshold

Projects below the PPP threshold — or those structured as government procurement rather than concessions — are governed by the Public Procurement and Supplies Administration Act B.E. 2560 (2017). This Act sets out the rules for competitive tendering, contractor qualification, contract award, and dispute resolution in public contracts. Thai and foreign businesses tendering for government work need to understand both regimes and which applies to a given opportunity.

How South Summit Can Help

Drawing on a decade of expertise in Thai public procurement and PPP law, South Summit advises both public sector bodies and private investors and developers on transaction structuring, concession agreement negotiation, procurement compliance, and dispute resolution across the full lifecycle of public infrastructure projects.

NGO Establishment

Establishing an International NGO in Thailand: The Two Legal Pathways

International non-governmental organisations seeking to operate in Thailand must navigate a specific regulatory framework that differs significantly from commercial business registration. There are two primary legal pathways — and choosing the wrong one can create significant operational and legal problems down the line.

Pathway One: National Office Establishment

Under the relevant ministerial regulations, an international NGO may apply to establish a national office in Thailand. This pathway is suited to organisations that intend to operate programmes directly in Thailand — employing staff, managing projects, and engaging with government counterparts. Approval requires a formal application to the relevant ministry, demonstration of the organisation's mission and track record, and ongoing reporting obligations. The national office does not have independent legal personality — it operates as an extension of the international organisation.

Pathway Two: Foundation Structure

The alternative is to establish a Thai-registered foundation under the Civil and Commercial Code. A foundation has independent legal personality and can hold assets, enter contracts, and employ staff in its own name. This structure offers greater operational autonomy but requires a governing board, a defined objective aligned with public benefit, and compliance with foundation reporting and audit requirements. Foreign control of Thai foundations is subject to limitations that must be carefully structured.

Choosing the Right Structure

The choice between these pathways depends on the organisation's operational model, funding sources, engagement with the Thai government, and long-term presence plans. Some organisations use both — a national office for programme implementation and a foundation for asset-holding or sub-granting. Getting the structure right at inception avoids costly restructuring and regulatory complications later.

How South Summit Can Help

South Summit has guided international NGOs through both pathways — from initial structural assessment and regulatory strategy through to submission, registration, and ongoing compliance. We are one of the few Thai law firms with dedicated expertise in this area.
