A practical guide to a supply or manufacturing contract with a Mainland China party

A supply or manufacturing contract with a Mainland China counterparty raises a set of questions that no single jurisdiction's counsel can answer alone. The law of the contract, the forum for disputes, the recognition of any award or judgment, and the day-two operational reality – the way the arrangement functions in practice once signed – sit across two distinct legal systems. Getting the governing-law and forum clause right at the drafting stage is not a formality. It is the structural decision that determines whether any remedy is reachable when things go wrong.

A well-constructed supply or manufacturing contract with a Mainland China party requires deliberate choices on governing law, forum, enforcement route, and contract language – choices made in sequence, before signature, under the Mainland's contract law regime and the cross-border enforcement architecture that links Hong Kong to the people's courts.

This guide sets out the practical sequence: the decision the reader faces, the steps in order, the gate at each stage, and the single mistake that recurs most often in cross-border supply arrangements.

What decision does the reader actually face?

The central decision is structural, not commercial. Before price, lead time, or quality standards, a party contracting with a Mainland China entity must resolve four anterior questions.

First, which law governs the contract? Mainland China applies its own civil-law–influenced contract statute. If the parties choose a foreign governing law, Mainland courts will in principle respect that choice for commercial contracts – but only within limits, and not where mandatory provisions of Mainland law apply. Choosing Hong Kong law brings a common-law system into a Mainland relationship; that choice has implications for interpretation, implied terms, and the remedies available.

Second, where are disputes resolved? The options are Mainland court litigation, Hong Kong court litigation, Mainland arbitration, or Hong Kong-seated international arbitration. Each produces a different enforcement pathway. An arbitral award from a Hong Kong-seated arbitration can be enforced in the Mainland under the Mainland–HK Arrangements. A Hong Kong court judgment can now be registered and enforced in the Mainland under the Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance (Cap. 645), in force 29 January 2024. These are different routes with different procedural requirements.

Third, in which language is the contract written, and which version controls? In Mainland proceedings, a Chinese-language contract that differs from an English-language version – even subtly, in translation – is the version that counts.

Fourth, what is the day-two operating reality? How are purchase orders issued, accepted, and varied? Where is the contract performed, and does that affect the enforceability of any agreed terms?

These four questions must be sequenced and resolved before the commercial terms are finalised. In our cross-border practice, the agreements that generate enforcement problems are overwhelmingly those where the structural questions were deferred.

Step 1: Choose the governing law with the enforcement outcome in mind

The governing-law choice is not simply a matter of familiarity or preference. It must be made with the enforcement outcome already in view.

If disputes will be resolved by Mainland courts, a Mainland-law governing clause removes a layer of legal-system friction. Mainland courts apply Mainland law efficiently when it is the chosen law. If the parties select a foreign law – say, Hong Kong law or English law – a Mainland court will in principle apply it, but the court's practical experience with foreign law is variable, and mandatory Mainland provisions override it in any event.

If disputes will be resolved by Hong Kong-seated arbitration, the governing law of the contract is a separate question from the lex arbitri (the law governing the arbitration procedure itself, which for a Hong Kong seat is the Arbitration Ordinance (Cap. 609)). Hong Kong law or English law as the governing law of a supply contract is well-suited to a Hong Kong-seated arbitration – the arbitral tribunal will apply it without translation difficulty.

What the governing law cannot do is override Mainland mandatory provisions where the contract is performed in the Mainland or concerns Mainland-situated activities. Product liability, environmental compliance, employment of Mainland workers, and certain IP rules are governed by Mainland law regardless of the contractual choice.

The practical position: for a pure goods-supply arrangement with limited Mainland performance obligations, Hong Kong or English law as the governing law, combined with a Hong Kong-seated arbitration clause, gives a coherent and enforceable package. For a manufacturing arrangement with deep Mainland operational content – factory-level quality control, local workers, on-site inspection – the governing-law choice requires more deliberation, and local Mainland legal input is essential.

The sequence above describes the standard analytical framework. Your contract turns on the specific jurisdictions engaged, the nature of performance, and the counterparty's entity type – which is where the governing-law decision is won or lost.

Step 2: Select the forum clause – and understand what each option produces

The forum clause determines which body resolves the dispute and, equally importantly, what the winning party then does with the result. These are inseparable questions.

Four realistic options exist for a cross-border Mainland–Hong Kong supply contract.

Option A – Mainland court litigation. Mainland people's courts have jurisdiction over disputes where the contract is performed in the Mainland, the counterparty is incorporated there, or the parties have chosen Mainland court jurisdiction. A judgment from a competent Mainland court in a civil or commercial matter can now be registered in Hong Kong under Cap. 645 – the regime that took effect on 29 January 2024. This is a material development. It means that a foreign party who obtains a Mainland judgment is no longer confined to the 2008 choice-of-court regime, which required an exclusive jurisdiction clause to engage the prior recognition mechanism.

Option B – Hong Kong court litigation. A Hong Kong court judgment in a civil or commercial matter can be enforced in the Mainland using the certified-copy and certificate procedure under Cap. 645. The old requirement that the parties have chosen the Hong Kong court exclusively has been removed. A connection-based test now applies. This is an important practical improvement – but the foreign party must still obtain an effective Hong Kong judgment first, which requires that the Hong Kong court has jurisdiction.

Option C – Mainland-seated arbitration. Arbitration before a Mainland institution (such as the China International Economic and Trade Arbitration Commission, known as CIETAC) produces a Mainland arbitral award. That award is enforceable in Hong Kong under the 1999 Arrangement between the Mainland and the HKSAR on mutual enforcement of arbitral awards, as supplemented in 2020. The 2021 amendment permits simultaneous enforcement applications in both jurisdictions.

Option D – Hong Kong-seated international arbitration. An award from a Hong Kong-seated arbitration is enforceable in the Mainland under the same Arrangement. Hong Kong arbitrations are governed by the Arbitration Ordinance (Cap. 609), which is modelled on the UNCITRAL Model Law and incorporates the HKIAC Administered Arbitration Rules where those rules are selected. The 2024 HKIAC Rules, effective 1 June 2024, contain updated provisions on emergency relief – ordinarily completed within 14 days of file transmission – and are familiar to international arbitration practitioners worldwide.

For most foreign parties entering a supply or manufacturing arrangement with a Mainland counterparty, Option D – HKIAC arbitration, Hong Kong seat, Hong Kong or English governing law – is the most commonly adopted structure. It provides a neutral forum, a well-tested set of procedural rules, and an established enforcement pathway to the Mainland. The choice is not universal: sector, counterparty, and transaction size all affect it.

We regularly advise on forum-clause selection for Mainland supply and manufacturing contracts across a range of sectors. The analysis depends on where performance sits, what assets the counterparty holds, and what the realistic enforcement scenario looks like.

Step 3: Draft the contract – language, structure, and operative provisions

With governing law and forum resolved, the drafting stage begins. Several points consistently distinguish contracts that function in practice from those that generate downstream problems.

Bilingual drafting with a designated controlling version. Where the Mainland counterparty is a PRC entity, Mainland courts and arbitral tribunals will work from the Chinese text. The contract must therefore be drafted bilingually – English and Simplified Chinese – with an explicit clause specifying which version controls in the event of conflict. Relying on a translation produced after a dispute has arisen is a structural error that recurs in cross-border supply arrangements.

Entity identification. The Mainland counterparty must be identified precisely. The Chinese legal name, unified social credit code (shehui xinyong daima – the identifier assigned to all PRC legal entities), and registered address should be stated verbatim. A mismatch between the contracting entity and the operating entity is a common source of enforcement difficulty.

Purchase order mechanics. A framework supply contract typically governs the ongoing relationship; individual purchase orders govern each shipment or production run. The contract must state clearly whether a purchase order creates a binding obligation on acceptance, how acceptance is communicated, and what happens to orders that are issued but not formally accepted. Gaps here are exploited in disputes over whether a particular transaction is covered.

Quality, inspection, and acceptance. Quality standards, inspection rights, and the consequences of rejection must be set out in operational terms that can be applied without reference to the contracting party's subjective expectation. Where international standards apply (such as ISO specifications or industry-specific testing protocols), reference them by designation and version. Vague quality provisions are the leading cause of mid-contract disputes in manufacturing arrangements.

Force majeure and material adverse change. Mainland law contains its own provisions on changed circumstances and force majeure (unforeseeable, unavoidable events beyond the party's control). A contractual force-majeure clause must be read alongside, not as a replacement for, those statutory provisions. If the parties wish to define the scope of force-majeure events more narrowly or more broadly than the Mainland default, that requires express drafting – and Mainland mandatory provisions still set a floor.

IP ownership and confidentiality. Where the manufacturing arrangement involves the transfer of designs, specifications, or technical know-how, the contract must address IP ownership explicitly. Under Mainland law, IP created by a Mainland manufacturer using the foreign party's know-how may, in some circumstances, be treated as jointly owned or separately registered. The contract should exclude that outcome expressly and provide for appropriate confidentiality obligations that survive termination.

What is the most common mistake, and how does the structure avoid it?

The single mistake that our desk sees most often in cross-border supply and manufacturing contracts is this: the commercial team agrees the forum clause (often "arbitration in Hong Kong") without specifying the institution, the seat, the rules, the language of the proceedings, or the number of arbitrators.

A clause that reads "all disputes shall be submitted to arbitration in Hong Kong" is not a complete arbitration agreement. It is an agreement to agree. In the event of a dispute, the counterparty can dispute the institution, the number of arbitrators, and the procedural rules. Litigation about the arbitration clause – often before the same Mainland court that the clause was designed to avoid – is a foreseeable outcome.

The structural fix is simple: the clause must name the institution (for example, HKIAC), the seat (Hong Kong), the rules (the HKIAC Administered Arbitration Rules as in force at the time of the request for arbitration), the language (English, or English and Chinese), and the number of arbitrators. A one-sentence institutional arbitration clause of this specification is enforceable; a vague clause is not.

The same error appears in governing-law clauses. "The laws of Hong Kong" is sufficient if the parties mean the law of the Hong Kong Special Administrative Region. "Hong Kong" alone – without "law" – has been argued, in proceedings we have observed, to mean the law of the PRC as applied in Hong Kong. The words matter.

If an earlier contract produced an unenforceable or disputed clause, a review of the existing document and the options for renegotiation or amendment is the starting point. Email info@lockhartyip.com to discuss the current position and what the routes still open look like.

Step 4: Map the day-two operating reality

A contract governs not only the dispute scenario but the daily operation of the supply relationship. Several practical points recur in Mainland manufacturing arrangements.

Payment terms and currency. Cross-border payments between a foreign entity and a Mainland entity involve Mainland foreign-exchange controls. The State Administration of Foreign Exchange (SAFE) regulates outbound and inbound payments. The contract must specify the currency of payment and the payment mechanism. Contractual payment terms that are inconsistent with SAFE requirements cannot be performed; the drafting must reflect the actual payment route the parties intend to use.

Delivery terms and title transfer. Where does risk of loss and title to goods pass? International commercial terms – Incoterms (a standardised set of trade terms published by the International Chamber of Commerce) – are widely used in Mainland export manufacturing. The selected Incoterm should be consistent with the delivery point, the insurance arrangements, and the customs clearance obligations. A mismatch between the Incoterm and the customs documents creates liability that the contract did not intend.

Contract variation and waiver. In practice, supply relationships are managed by email, messaging, and informal amendment. Mainland courts and arbitral tribunals will give effect to conduct that amounts to contractual variation, even if the contract contains a "no oral modification" clause. Where the parties intend the written contract to govern, the variation mechanism must be stated and followed consistently in practice.

Term, termination, and exit. The contract should specify the initial term, renewal mechanics, and termination rights – both for cause (breach, insolvency, change of control) and for convenience (if any). Exit provisions matter: where the manufacturer holds tooling, moulds, or inventory belonging to the foreign party, the contract must specify the return or transfer mechanism on termination. Tooling recovery disputes are a recurring feature of Mainland manufacturing exits.

Decision checklist: questions to answer before signature

The following questions form a practical gate-check before a supply or manufacturing contract with a Mainland China party is executed. If any question cannot be answered, the step it represents is incomplete.

• Is the Mainland counterparty's Chinese legal name, unified social credit code, and registered address verified against the PRC enterprise registration system?
• Has the governing law been chosen deliberately, with Mainland mandatory provisions identified and addressed?
• Does the arbitration or jurisdiction clause name the institution, seat, rules, language, and number of arbitrators – or the specific court and basis of jurisdiction?
• Is the contract bilingual, with the controlling language version specified?
• Have purchase-order mechanics been documented, including what constitutes acceptance and how variations are made?
• Are quality standards, inspection rights, and rejection consequences operationally precise?
• Have IP ownership, know-how, and confidentiality been addressed for all technology or designs transferred in the arrangement?
• Are payment terms consistent with applicable foreign-exchange rules?
• Has the Incoterm been selected consistently with the delivery point, insurance, and customs obligations?
• Are termination rights and tooling-recovery mechanics specified?

Each of these items corresponds to a step in the sequence above. A contract that passes every gate is not guaranteed to be dispute-free – no contract is – but it is one where the parties have made deliberate, informed choices that can be applied and enforced.
