Note: Since 2022, RCEP has progressively entered into force for its members and has now entered a stage of deeper practical application. In practice, however, many cross-border enterprises still regard it as “another free trade agreement” and continue to plan their supply chains using a traditional bilateral FTA mindset, thereby overlooking the more institutionally valuable origin cumulation rule under RCEP.
Provided that the agreement’s rules of origin and product-specific rules are satisfied, RCEP allows originating materials and processing operations from member states to be cumulated, enabling enterprises to allocate raw materials, components and production processes more flexibly within the region, rather than simply concentrating all production stages in a single country. This rule merits particular attention from Chinese enterprises that have already established regional headquarters, trading platforms or supply chain nodes in Singapore.
It should be noted in particular that the RCEP cumulation rule does not mean that goods automatically acquire RCEP originating status merely by being transshipped, packaged or distributed through Singapore. Enterprises still need to assess, on an item-by-item basis and with reference to the specific product tariff classification, product-specific rules, regional value content, processing operations and proof of origin documents, whether the goods qualify for preferential tariff treatment.
This article focuses on the RCEP origin cumulation rule, compares its key differences with traditional bilateral FTAs, analyzes three practical China-Singapore linkage scenarios, and reviews the compliance points enterprises should note when applying the rule.
01 What Is the Origin Cumulation Rule?
Before understanding the cumulation rule, it is helpful to first understand the significance of origin. In international trade, whether a product can enjoy preferential tariff treatment under an FTA depends on whether it has “originating status” under that FTA framework. The traditional way of determining origin is to examine whether the processing value added in a single country reaches the prescribed threshold.
The RCEP cumulation rule removes the “single country” limitation. Provided that the agreement’s rules of origin and product-specific rules are satisfied, RCEP allows qualifying originating materials and processing operations from member states to be cumulated, thereby connecting the 15 member states into a regional production network to a certain extent. This means:
- Precision components procured from Japan are assembled in Singapore.
- Chemical raw materials imported from South Korea are processed into semi-finished products in China and then shipped to Singapore for final processing.
- Raw materials from ASEAN countries are primarily manufactured in China.
If the relevant raw materials, components and processing operations meet the RCEP origin rules, and the target product satisfies the corresponding regional value content, tariff classification change or other product-specific rules, the final product may be exported to other RCEP member markets at reduced or even zero tariffs. This rule significantly reduces the compliance cost of having to “complete all production processes in a single country” in order to meet origin thresholds.
Therefore, the value of the RCEP cumulation rule does not lie in the idea that goods enjoy preferences merely by passing through a member state, but in helping enterprises lawfully cumulate qualifying originating materials, processing operations and value-added segments across the region. Enterprises still need to assess, item by item and with reference to the specific product tariff classification, product-specific rules, regional value content, tariff classification change, processing operations and proof of origin documents, whether the final product qualifies for preferential tariff treatment.
02 How Does It Differ from Traditional Bilateral FTAs?
The most direct way to understand the value of the cumulation rule is to compare its fundamental differences with the origin rules of traditional bilateral FTAs.
The logic of traditional bilateral FTAs is closer to a tariff arrangement between two countries. For origin determination, enterprises usually need to complete a relatively high proportion of production and value addition within a single contracting party to obtain preferential originating status. Raw materials, components or processing operations from third countries generally cannot automatically be included in origin cumulation. This imposes significant restrictions on the cross-border configuration of supply chains; enterprises often have to concentrate core processes in one country, even when it would be more cost-effective and efficient to distribute them across other countries in the region.
The most significant change under the RCEP cumulation rule is that, for the first time, it treats the 15 member states as a single production area. Materials with RCEP originating status obtained by enterprises in member states, as well as processing and value addition that meet the rule requirements, may be cumulated in the origin determination. Supply chains are no longer limited to two countries but can be flexibly configured within the region.
With respect to compliance documentation, under RCEP enterprises may use a certificate of origin or, where the member state’s implementation requirements permit, an origin declaration. Enterprises that wish to use the self-declaration mechanism should first confirm whether the member state in which they operate applies an approved exporter or certified exporter regime, and complete the corresponding registration or authorization.
A typical case in practice is as follows: a Chinese-invested enterprise has an assembly plant in Vietnam, procures components from South Korea and Japan, and exports finished products to Australia. Under the traditional bilateral FTA system, the Vietnam plant had difficulty obtaining preferential tariff treatment because it could not meet the “bilateral cumulation” requirement. Under the RCEP cumulation rule, however, the processing in South Korea, Japan and Vietnam may be combined, meeting the origin threshold and qualifying for preferential tariff rates. This is precisely the core value released by the cumulation rule at the supply chain level—allowing enterprises to plan production capacity layout according to commercial logic rather than origin restrictions.
03 Three Practical Scenarios for China-Singapore Linkage
Specifically, in the China-Singapore trade corridor, the application of the cumulation rule is mainly reflected at three levels:
1. Using Singapore as a Regional Supply Chain Management Node
Many Chinese enterprises have established regional headquarters or trading platforms in Singapore. Under the RCEP cumulation rule, Singapore can serve as an important node for supply chain management, order coordination, warehousing and distribution, quality inspection arrangements and regional distribution. It should be noted, however, that merely transshipping goods through Singapore, switching documents, labeling or simple packaging is usually insufficient to change the origin of the goods. Only if the source of relevant materials, processing operations, cost composition and proof of origin documents all comply with RCEP rules can the Singapore node truly become part of tariff optimization.
2. Multi-Country Procurement, Manufacturing in China and Distribution from Singapore
Chinese enterprises procure raw materials or core components from RCEP members such as Japan, South Korea and Australia, complete manufacturing and processing in China, and then distribute the products to Southeast Asian markets through a Singapore platform. The cumulation rule safeguards origin compliance across the entire chain and prevents the loss of tariff preferences due to dispersed procurement sources.
3. The New International Land-Sea Trade Corridor and Western China’s Outbound Access
The RCEP cumulation rule has institutional synergies with the China-Singapore Connectivity Initiative (Chongqing) and the New International Land-Sea Trade Corridor. Enterprises in western China can use the “Western China–Singapore–ASEAN” corridor to flexibly arrange production, warehousing and transshipment within the region under the cumulation rule, reducing dependence on a single shipping route while maintaining tariff preferences.
04 Compliance Points Enterprises Should Note
- Proof of origin documents.
Under RCEP, enterprises may use a certificate of origin or, where the member state’s implementation requirements permit, an origin declaration. Enterprises that wish to use the self-declaration mechanism should first confirm whether the member state in which they operate applies an approved exporter or certified exporter regime, complete the corresponding registration or authorization, and establish a complete origin record-keeping system.
- Completeness of production and processing records.
Enterprises need to retain records of raw material procurement, production and processing, and cost accounting to demonstrate that their products meet the relevant requirements of the RCEP origin rules. For products subject to the regional value content rule, RVC 40% is a relatively common threshold, but different products may be subject to different product-specific rules, including tariff classification change, specified processing operations, or a choice among multiple rules. The record retention period is generally at least three years after export of the product.
- Avoid suspicion of “origin laundering.”
If an enterprise only performs simple packaging, labeling or other operations in Singapore that do not constitute a substantial transformation, it may be found to be circumventing tariffs and may face customs verification. The substantial transformation standard generally requires that the product undergo a change in tariff classification or that the processing value added reach a certain proportion.
- Monitor tariff concession progress in each member state.
RCEP member states have different tariff concession schedules. For some products, zero tariffs will be phased in over 10–20 years. When planning supply chains, enterprises should check the latest tariff commitment schedules of target markets.
- Choosing between bilateral FTAs and RCEP.
RCEP is not always the optimal choice. For certain products, the China–Singapore bilateral FTA or the China–ASEAN FTA may offer lower tariff rates. Enterprises are advised to compare tariffs for specific products and choose the most favorable agreement.
Conclusion
The essence of the RCEP origin cumulation rule is to institutionally “piece together” the 15 member states into one production area. For Chinese enterprises, this means upgrading supply chain deployment from passively adapting to origin restrictions to proactively using a multi-country coordinated institutional tool for production capacity planning.
Singapore, as an RCEP member whose legal maturity, logistics efficiency and financial convenience are all in the first tier, is naturally suited to serve as a supply chain management hub. Taking the RCEP cumulation rule into account in cross-border trade structuring may bring significant tariff cost improvements and supply chain efficiency gains.
Institutional tools do not automatically translate into corporate competitiveness; enterprises must proactively understand the rules, restructure procurement and production capacity layouts, and establish compliance record-keeping systems. As competition in cross-border trade becomes increasingly intense, those that can make good use of the rules gain an additional moat.
