International Trade Law sits at the intersection of public international rules (WTO, treaties, FTAs) and a wide array of domestic laws that actually make cross-border commerce happen, regulate its risks, and enforce obligations. Below, I map with short definitions and practical links the main domestic and international legal families that feed into, shape, or are shaped by International Trade Law. Use this as a checklist when you draft trade advice, compliance notes or classroom material.


1) Public international / trade treaties (the backbone)

Definition: multilateral rules (WTO Agreements, GATT, GATS, TRIPS, TBT, SPS, AD/SCM, etc.) that set minimum obligations between States and create a dispute-settlement machinery.
Why it matters: these rules determine what States can do to tariffs, subsidies, IP protection, sanitary measures, and trade remedies; domestic measures must be interpreted against them when a State is put into a WTO panel or FTA arbitration.


2) Domestic foreign-trade & customs law (implementation + enforcement)

Definition: national statutes and administrative regimes that permit/prohibit imports/exports, issue licences, levy tariffs and impose customs penalties.
Relation: They are the operational arm of trade law tariff schedules, customs valuation, rules of origin and export controls are applied under domestic statutes and customs procedure (and often must comply with WTO commitments). In India, for example, the Foreign Trade (Development & Regulation) Act (DGFT) and the Customs Act are the primary instruments used to implement trade policy. 


3) Tax law (customs duties, IGST, income tax consequences)

Definition: domestic tax statutes (customs, GST/IGST, corporate and withholding tax).
Relation: Tariffs and indirect taxes change the landed cost and competitiveness of goods; IGST/Central/State GST rules determine taxation at import/export and interplay with customs valuation and duty-drawback or refund schemes. Tax laws also shape investment and pricing decisions for exporters/importers. 


4) Contract & commercial law (international sale, payment, delivery)

Definition: the rules that govern how parties make and enforce contracts (sales contracts, letters of credit, carriage contracts).
Relation: Most international trade disputes begin as contract disputes. Documentary credits and trade finance follow the ICC rules (UCP 600 / eUCP) and bank practice, which practitioners treat as quasi-mandatory in documentary credit workflows. Governing law, INCOTERMS (commercial practice), and force-majeure clauses all operate inside this layer. 


5) Company law, securities & foreign investment law

Definition: corporate law (company formation, directors’ duties), securities regulation and investment-screening regimes.
Relation: Trade facilitation, export incentives and foreign-investor protections (and restrictions) are administered through company and investment law. Cross-border M&A, joint ventures, and investment treaty protections (BITs/ISDS) sit at the interface of trade and investment law. Institutional forums like ICSID handle investor–state claims arising from trade-related regulation.


6) Competition (antitrust) law

Definition: rules prohibiting anti-competitive agreements, abuse of dominance and unfair mergers.
Relation: Competition law shapes market access and remedies for anticompetitive conduct by exporters/importers (e.g., price-fixing cartels affecting cross-border markets); competition authorities sometimes coordinate with trade regulators where anti-dumping or subsidy issues intersect market distortions.

7) Intellectual Property Law (TRIPS + national IP statutes)

Definition: patent, copyright, trademark, GI, trade secrets and enforcement law.
Relation: IP rules (especially TRIPS) are trade rules — they affect market access for technology and pharmaceuticals, licensing, border measures (seizure of counterfeit goods) and trade disputes over IP thresholds and exceptions (public health, exhaustion). Domestic IP statutes are often framed to meet TRIPS minima. 


8) Standards, labelling & conformity (TBT / SPS / national standards)

Definition: product standards, testing, labelling and sanitary/phytosanitary rules.
Relation: These are frequent non-tariff measures that can impede trade. WTO’s TBT and SPS frameworks allow legitimate protection of health/environment but prohibit disguised protectionism by national standard bodies (e.g., BIS; FSSAI for food), therefore play an important trade role. 


9) Environmental & climate law

Definition: domestic environmental statutes and international environmental agreements (e.g., Paris Agreement).
Relation: Environmental regulation (emissions rules, ecolabelling, carbon border measures) affects competitiveness and can generate trade disputes (e.g., compatibility with WTO rules, green subsidies, fisheries subsidies). Recent WTO work on fisheries subsidies shows the growing overlap of trade & environment policy. 


10) Labour & human-rights law

Definition: national labour laws and ILO conventions.
Relation: Labour standards (working conditions, minimum wages) can influence trade policy (e.g., preferential market access conditional on labour compliance), and FTAs increasingly reference labour and human-rights obligations, so trade lawyers must flag workplace/regulatory risk in supply chains. 


11) Transport, maritime & carriage law

Definition: rules governing carriage of goods by sea, road, air (e.g., Hague/Visby rules, Merchant Shipping/carriage acts).
Relation: Liability, shipping documents, bills of lading and multimodal transport contracts directly affect who bears loss, the timing of title transfer and insurance claims in cross-border trade. (Note: carriage law references see local statute collections for the latest Indian shipping/carriage enactments.)


12) Banking, payments & foreign-exchange law (FEMA, trade finance rules)

Definition: FX controls, RBI/central bank rules, payments regulations and trade-finance norms.
Relation: FEMA and RBI rules govern remittances, trade credits and external borrowings; trade finance instruments (LCs, guarantees) operate under private rules + central-bank/FX controls. Compliance here is vital for cross-border settlement. 


13) Dispute resolution (courts, arbitration, ISDS, WTO panels)

Definition: domestic courts, international commercial arbitration (UNCITRAL Model Law), investor-State arbitration (ICSID), and WTO dispute settlement.
Relation: Choice of forum and enforcement are core trade concerns — arbitral awards and WTO panel findings both shape how States and businesses design measures and contracts; arbitration statutes (e.g., India’s Arbitration & Conciliation Act implementing UNCITRAL principles) are central to enforcing cross-border commercial outcomes. 

14) Criminal & enforcement laws (customs offences, AML/PMLA)

Definition: smuggling, customs fraud, money-laundering statutes and enforcement procedures.
Relation: Trade-based money laundering, mis-invoicing, smuggling and sanctions evasion attract criminal enforcement; trade advice must therefore cover criminal risk and compliance (KYC, AML, customs reporting). 


15) Data protection & digital trade

Definition: national data-protection statutes and international rules on cross-border data flows.
Relation: Digital trade (services, e-commerce, fintech) is shaped by data-transfer restrictions and privacy law; many FTAs now include digital trade chapters. In India, the Digital Personal Data Protection Act (DPDP) introduces cross-border transfer controls and compliance obligations relevant to e-commerce and trade services. 


Practical takeaways for a practitioner

  1. Map obligations top-down: start from WTO/FTA obligations → domestic enabling statutes → implementing regulations → sectoral standards (IP, environment, health). 

  2. Watch non-tariff measures early: standards, conformity, and export/import licensing are often the actual barriers to market access. 

  3. Integrate compliance: trade law advice must include customs, taxation (IGST), FX, AML, and sectoral regulators (FSSAI/BIS) to be operationally useful.

  4. Design dispute strategy at the outset: pick law/forum clauses with enforcement in mind — arbitral seat, ICSID access, and the scope of WTO remedies (State-to-State).
