China–Cambodia AEO mutual recognition goes live: what GACC Announcement No. 138 means for certified traders | 中柬海关AEO互认正式实施：海关总署138号公告对认证企业的操作要点
Overview
The Arrangement on Mutual Recognition between the China Customs Advanced Certification System and the Cambodia Customs “Authorised Economic Operator” Programme took effect on 15 September 2026. The General Administration of Customs (海关总署) published Announcement No. 138 of 2026 on 11 September to operationalise it, followed by an official interpretation on 14 September.
For companies holding China’s advanced AEO certification (海关高级认证企业) that trade with Cambodia — and for importers sourcing from Cambodian AEOs — the arrangement adds a second, operational layer of facilitation on top of the tariff preferences already available under the China–Cambodia free trade agreement.
What the mutual recognition delivers
Under the arrangement, the two customs administrations recognise each other’s AEOs: Cambodia recognises China’s advanced-certification enterprises as mutual-recognition AEOs, and China recognises enterprises certified under Cambodia’s AEO programme. On import consignments, mutual-recognition AEOs receive:
- a lower inspection rate;
- priority examination where physical inspection is required;
- a designated customs liaison officer responsible for handling AEO enterprises’ clearance problems;
- a commitment to provide rapid clearance to the greatest extent for goods imported from the partner’s AEOs after major infrastructure recovers from trade disruption.
These are the standard AEO mutual-recognition benefits China now extends across its network; the operational value is in reduced dwell time and fewer surprise inspections on qualifying flows.
The code mechanics: two fields, two formats
The announcement sets out precisely how AEO status travels with the goods:
- Exporting from China to Cambodia. A Chinese advanced-certification enterprise must inform its Cambodian importer of its AEO code — the prefix AEOCN plus the 9th to 17th digits of the unified social credit code (for example, AEOCN123456789). The Cambodian importer declares the code under Cambodian customs rules; Cambodian customs confirms the Chinese AEO status and applies the facilitation.
- Importing from Cambodia into China. The Chinese importer must fill the Cambodian AEO code — the country code KH plus a 7-digit enterprise code (for example, KH2025008) — in two places: the “overseas consignor code” field of the import declaration and the “consignor AEO enterprise code” field of water- or air-freight manifest data. Chinese customs confirms the Cambodian AEO status and applies the facilitation.
Getting these fields right is the practical difference between receiving the benefits and moving through the queue as a regular trader; mismatches in the manifest fields are the usual failure point in the early months of a new mutual-recognition arrangement.
Where Cambodia sits in China’s AEO network
China has now signed AEO mutual-recognition arrangements with 34 economies covering 60 countries (regions), of which 54 countries (regions) have implemented the recognition — the largest number of signed arrangements and implemented recognitions in the world, per the GACC and local customs publicity. Cambodia is a major Belt-and-Road partner and ASEAN member; two-way trade has grown steadily, and under the China–Cambodia free trade agreement more than 90% of Cambodian goods entering China enjoy zero tariffs.
The sequence matters for traders: tariff preferences cut the duty bill, and AEO mutual recognition cuts time, uncertainty and inspection-related logistics costs. The two layers stack for enterprises that hold both a preference claim (via the origin system) and advanced certification.
Practical steps for certified traders
- Confirm your certification status and code. Advanced-certification enterprises should verify the AEO code format (AEOCN + digits 9–17 of the unified social credit code) and brief their Cambodia-facing sales and documentation teams.
- Update customer and supplier master data. Exporters should pass the AEO code to Cambodian buyers in advance of the first shipment; importers should collect the “KH + 7-digit” codes from Cambodian AEO suppliers and load them into declaration and manifest templates.
- Brief brokers on the two fields. The consignor code field on the declaration and the AEO field on water/air manifests must both be completed for inbound Cambodian AEO goods.
- Pair the AEO benefit with origin claims. For Cambodian-origin imports, the zero-tariff treatment under the China–Cambodia FTA (or RCEP, where applicable) operates through preferential origin declarations; AEO status does not replace origin documentation.
- Use the liaison-officer channel. Certified enterprises facing clearance friction on China–Cambodia flows should raise the case through the designated liaison officer mechanism rather than the general queue.

中柬海关AEO互认正式实施：海关总署138号公告对认证企业的操作要点
概述
《中华人民共和国海关总署和柬埔寨海关与消费税总署关于中国海关企业信用管理制度与柬埔寨海关”经认证的经营者”制度互认的安排》自2026年9月15日起正式实施。海关总署于9月11日发布2026年第138号公告予以落地，并于9月14日发布官方解读。
对持有中国海关高级认证、与柬埔寨有贸易往来的企业，以及自柬埔寨AEO企业进口的采购方而言，这份安排在中柬自贸协定关税优惠之上叠加了第二层操作性的通关便利。
互认带来什么
安排下双方海关相互认可对方AEO：柬埔寨海关认可中国高级认证企业为互认AEO企业，中国海关认可经柬埔寨AEO制度认证的企业。进口货物通关时，互认AEO企业可获得：
- 较低的进口查验率；
- 需要实货检查的货物优先查验；
- 指定海关联络员，负责沟通处理AEO企业通关中遇到的问题；
- 在主要基础设施从贸易中断恢复后，致力于最大限度为进口自对方AEO企业的货物提供快速通关。
这是中国AEO互认网络向全球推广的标准便利组合；其操作价值在于合格流量通关停留时间更短、布控查验带来的物流不确定性更低。
编码操作：两个字段、两种格式
公告明确了AEO身份随货流转的填报规则：
- 中国对柬出口。 中国高级认证企业须将AEO编码——前缀AEOCN加统一社会信用代码第9至17位主体标识码（如AEOCN123456789）——告知柬埔寨进口商；进口商按柬埔寨海关规定申报，柬埔寨海关确认中国AEO身份后给予便利。
- 自柬埔寨进口。 中国进口商须在两处填报柬埔寨AEO编码——国别代码KH加7位企业编码（如KH2025008）：报关单“境外发货人”栏目中的”境外发货人编码”栏，以及水、空运货运舱单中的“发货人AEO企业编码”栏。中国海关确认柬埔寨AEO身份后给予便利。
字段填报正确与否，直接决定企业能否拿到便利：新互认安排实施初期，舱单字段不匹配是最常见的失分点。
柬埔寨在中国AEO网络中的位置
截至公告发布，中国已与34个经济体签署AEO互认协议，覆盖60个国家（地区），其中54个国家（地区）已实施互认——签署数量与实施数量均居全球首位。柬埔寨是共建”一带一路”重要国家和东盟成员国；在中柬自贸协定下，超九成柬埔寨输华商品已实现零关税。
对贸易商而言，顺序很清楚：关税优惠降低税负成本，AEO互认降低时间、不确定性与查验相关物流成本；同时持有优惠原产地资格与高级认证的企业，两层红利可以叠加。
认证企业的实操清单
- 确认认证状态与编码。 高级认证企业应核对AEO编码格式（AEOCN+统一社会信用代码第9–17位），并向对柬销售与单证团队交底。
- 更新客户与供应商主数据。 出口方应在首票货物发运前把AEO编码告知柬埔寨买方；进口方应向柬埔寨AEO供应商收集”KH+7位”编码，写入报关与舱单模板。
- 向报关行交底两个字段。 柬埔寨AEO货物进口申报时，报关单”境外发货人编码”栏与水空运舱单AEO栏须同时填报。
- AEO便利与原产地优惠并行使用。 柬埔寨原产货物进口享受中柬自贸协定（或适用时的RCEP）零关税走的是优惠原产地申报；AEO身份不能替代原产地单证。
- 用好联络员通道。 认证企业在中柬流向遇到通关摩擦，应通过指定联络员机制反映，而非走普通渠道排队。
