EAC CoC（TR CU Certificate of Conformity）合格证书完整说明 一、基础定义 EAC CoC，全称海关联盟技术法规合格证书（Сертификат соответствия ТР ТС / Certificate of Conformity to TR CU），俗称EAC 合格证书，是欧亚经济联盟 EAEU（俄罗斯、哈萨克斯坦、白俄罗斯、亚美尼亚、吉尔吉斯斯坦）强制第三方准入认证，属于 EAC 两大认证类型里管控高风险产品的法定证书。 别名：CU-TR CoC、TR CU 合格证书、海关联盟合格证书 核心作用：证明产品完全符合欧亚联盟统一安全技术法规 TR CU，可五国通用清关、销售、安装；产品必须印刷EAC 标志 监管系统：证书全部录入联盟官方 FGIS 数据库，海关、市场监管可联网核验真伪 二、核心法律属性 第三方独立发证，公信力最高 证书只能由EAEU 官方授权认证机构（Notified Body） 签发，企业不能自行出具；发证机构对产品合规承担连带责任，出现安全事故时机构与进口商共同追责。 高风险产品唯一合规凭证 各 TR CU 法规明确划分品类：高危产品禁止用 DoC 符合性声明替代 CoC，无 CoC 证书货物会被海关扣货、退回、销毁，境内流通会高额罚款、强制下架。 一次认证，五国通用 统一替代俄罗斯 GOST-R、哈萨克斯坦 GOST-K、白俄罗斯 ST-BY 等各国单独认证，不用分别做国别认证【详细】

结论：二者完全等同，只是叫法不同 EAC CoC = TR CU CoC = 海关联盟合格证书 1、名称来源拆解 TR CU CoC TR CU = Technical Regulation of Customs Union，海关联盟技术法规； CoC = Certificate of Conformity，合格证书； 全称：Certificate of Conformity to TR CU，直译「依据海关联盟技术法规出具的合格证书」，是官方标准书面名称。 EAC CoC EAC 是海关联盟统一合格标识（ЕАС）的缩写，市场行业内习惯用证书对应的标志代称证书，简化叫 EAC 证书； 高风险第三方发证版本就叫 EAC CoC，用来区分企业自签的 EAC DoC 符合性声明。 2、核心统一点（完全是同一份证书） 发证机构：均为欧亚经济联盟官方授权第三方认证机构； 法律效力：都依据 TR CU 各条强制技术法规； 使用范围：俄、哈、白、吉、亚美尼亚五国通用； 备案系统：全部录入联盟统一 FGIS 数据库； 外观：证书上同时标注ТР ТС、EAC 标识； 适用产品：机械、防爆、压力容器、玩具、高压电气等高风险品类。 3、行业叫法区分（日常沟通习惯） 官方文件、法规、认证机构正式报告：多用 TR CU Certificate of Conformity（TR CU CoC） 外贸、报关、工厂口语简化称呼：统称 EAC 证书 / EAC CoC 补充区分（避免混淆） 整套 EAC 准入分两类文件，不要搞混： TR CU CoC（EAC CoC）合格证书：第三方机构发证，高危产品强制； TR CU DoC（EAC DoC）符合性声明：进口商自行签署，低风险产品使用【详细】

Russia GOST R Certification — Full Official Introduction (2026 Current Rules) 1. Basic Definition & Regulatory Background 1.1 Full Name & Authority GOST R = Государственный стандарт России (State Standard of the Russian Federation) Regulator: Rosstandart (Federal Agency for Technical Regulation and Metrology of Russia) Legal basis: Federal Law No.184-FZ On Technical Regulation Russia Government Decree No.2425 (mandatory product catalogue for national conformity assessment) Core principle of priority: EAEU TR CU (EAC) unified regulations > Russian national GOST R standards If your product is covered by any EAEU Technical Regulation (TR CU), only EAC certificate/declaration is legally valid for Russia customs clearance; GOST R alone will be rejected. GOST R certification is only mandatory for goods without matching TR CU EAEU regulations. 1.2 Validity Territory GOST R documents are exclusively valid inside the Russian Federation. They cannot replace GOST-K (Kazakhstan), GOST-B (Belarus), or EAC certificates for shipments to other EAEU member states. 1.3 Conformity Mark: CTP (Former PCT) Official circular mark: СТР / CTP (old PCT logo fully phased out after June 2021) Mandatory marking rules: Printed on product body, nameplate, outer packaging, Russian user manuals Minimum mark height ≥8 mm; QR code for official database verification required since 2025 Voluntary GOST R mark must add Russian text Добровольная сертификация next to CTP logo【详细】

GOST Standards & GOST Certificate of Conformity (Full English Version) 1. What are GOST Standards? 1.1 Basic Definition GOST = Государственный Стандарт (Gosudarstvennyy Standart) Literally: State Standard. Originated in the Soviet Union as unified technical specifications covering safety, mechanical performance, electrical parameters, climate resistance, chemical limits, measurement accuracy, labeling and test methods. After USSR dissolution, each country developed its own national GOST standard series with suffix codes: GOST R: Russian Federation national standards (main focus here) GOST-K: Kazakhstan national standards GOST-B: Belarus national standards 1.2 Structure of a GOST Standard Number Example: GOST 15150-69 GOST = standard family 15150 = serial code (climate environmental testing) 69 = year of issuance Common widely-used GOST R standards: GOST 60335 series: Household appliance safety GOST 30804 series: EMC electromagnetic compatibility GOST 15150-69: Cold/heat/humidity environmental test (-25℃ / -50℃ extreme cold grades) GOST R 50030: Low-voltage switchgear safety GOST R 51136: Construction material flame retardancy 1.3 Legal Hierarchy Rule (Critical 2026 Rule) TR CU (EAEU Technical Regulations) > GOST Standards If a product falls under any EAEU TR CU regulation (low voltage, machinery, toys, PPE, EMC), the unified union regulation overrides national GOST standards. Only EAC certification is accepted for customs clearance; GOST CoC alone is invalid. GOST R standards apply only to products without matching TR CU Special railway equipment, high-voltage gear above 1kV, special coatings, fertilizers, unique measuring instruments have no EAEU unified rules and must comply with dedicated GOST R national standards. GOST standards set the technical test benchmarks for issuing GOST Certificate of Conformity. All lab tests must follow the corresponding GOST standard clauses【详细】
