Foreign companies sourcing from China must navigate at least 6 separate government portals to remain compliant, from GACC customs clearance to MOFCOM export controls and SAMR product standards. Each portal has distinct registration procedures, language interfaces, and update cycles. Missing even one can result in customs holds, shipment delays, or compliance penalties. This directory maps every essential Chinese government portal for sourcing compliance, with practical navigation tips for foreign businesses.
China’s sourcing regulatory framework is governed primarily by the PRC Customs Law (海关法, hǎiguān fǎ), the PRC Foreign Trade Law (对外贸易法, duìwài màoyì fǎ), and the PRC Product Quality Law (产品质量法, chǎnpǐn zhìliàng fǎ). Each law delegates specific enforcement responsibilities to different government agencies, each maintaining its own online portal. Understanding which portal to use for which compliance task is the first step toward efficient China sourcing operations.
GACC — General Administration of Customs: The Primary Sourcing Portal
The General Administration of Customs (海关总署, hǎiguān zǒngshǔ), or GACC, operates the most critical portal for foreign buyers: the China International Trade Single Window (中国国际贸易单一窗口, zhōngguó guójì màoyì dānyī chuāngkǒu) at singlewindow.cn. This platform handles customs declaration, tariff classification queries, import/export license applications, and duty payment. As of 2025, over 95% of China’s customs declarations are processed through this single window system.
Key features for foreign businesses include the tariff query function (税率查询, shuìlǜ cháxún) — enter your product’s HS code (海关编码, hǎiguān biānmǎ) to see the applicable MFN tariff rate, VAT rate, and any consumption tax. The portal also hosts: GACC Decree 248 (overseas food manufacturer registration), GACC Decree 256 (overseas production facility registration for imported food), and the AEO certification portal (Authorized Economic Operator, which reduces inspection rates by 60–80%). Company registration on the Single Window requires a valid Unified Social Credit Code (统一社会信用代码, tǒngyī shèhuì xìnyòng dàimǎ) and takes approximately 3–5 business days for foreign enterprises.
MOFCOM — Ministry of Commerce: Trade Policy and Licensing
The Ministry of Commerce (商务部, shāngwù bù) portal at mofcom.gov.cn is the source for foreign trade regulations, import/export licensing, and the Negative List (负面清单, fùmiàn qīngdān). Under the PRC Foreign Trade Law Article 15, certain goods require import or export licenses. The MOFCOM portal publishes the most current version of the Catalogue of Goods Subject to Import License Administration and the Catalogue of Technologies Prohibited or Restricted from Import.
For sourcing compliance specifically, MOFCOM’s Department of Foreign Trade (对外贸易司, duìwài màoyì sī) publishes annual updates to: tariff rate quotas for agricultural goods, automatic import license procedures, and the dual-use item export control list in coordination with the Export Control Law. The portal also hosts the China FTA Network (中国自由贸易区服务网, zhōngguó zìyóu màoyì qū fúwù wǎng) at fta.mofcom.gov.cn, which lists preferential tariff rates under China’s 19 free trade agreements. Companies should check this portal quarterly — MOFCOM publishes policy circulars in both Chinese and English, though English translation may lag by 2–4 weeks.
SAMR — State Administration for Market Regulation: Product Standards and CCC Certification
The State Administration for Market Regulation (国家市场监督管理总局, guójiā shìchǎng jiāndū guǎnlǐ zǒngjú) portal at samr.gov.cn is the definitive source for product compliance standards. SAMR administers the National Standardization Administration (国家标准化管理委员会, SAC), which publishes all GB mandatory standards and GB/T recommended standards. Over 2,000 GB standards are currently in force across industrial sectors, and new standards are published monthly.
The CCC Certification Portal (CCC认证查询, rènzhèng cháxún) at cx.cnca.cn allows foreign companies to verify whether their product requires China Compulsory Certification (CCC) — approximately 17 categories of products, including electronics, automotive parts, and household goods. SAMR’s Enterprise Credit Information Publicity System (国家企业信用信息公示系统, guójiā qǐyè xìnyòng xìnxī gōngshì xìtǒng) at gsxt.gov.cn allows you to check a supplier’s registration status, annual reports, and any administrative penalties — an essential pre-sourcing due diligence step for all foreign buyers.
CNCA — Certification and Accreditation Administration
The Certification and Accreditation Administration (国家认证认可监督管理委员会, guójiā rènzhèng rènkě jiāndū guǎnlǐ wěiyuánhuì) at cnca.gov.cn governs all product certification bodies, inspection agencies, and laboratory accreditation in China. For foreign companies, CNCA’s portal is essential for: verifying whether a certification body is authorized to issue CCC certificates, checking the status of overseas testing lab recognition, and understanding China’s energy-label and environmental-product certification requirements.
CNCA publishes the List of Compulsory Product Certification Implementing Rules, which maps each product category to its specific testing standards and certification procedures. As of 2026, CNCA operates a digital certification platform allowing foreign manufacturers to submit CCC applications electronically — reducing processing time from 12 weeks to approximately 8 weeks for straightforward product categories. Portal registration requires company articles of association (公司章程, gōngsī zhāngchéng) and a notarized power of attorney.

Provincial and FTZ Portals: Local Implementation Varies
Provincial commerce bureaus (商务厅, shāngwù tīng) and Free Trade Zone (自由贸易试验区, zìyóu màoyì shìyàn qū) authorities maintain their own portals implementing national regulations with local variations. The following portals are essential for foreign companies sourcing through specific regions:
- Shanghai FTZ Portal (china-shftz.gov.cn) — Pioneered the “single window” concept; offers deferred duty payment and centralized customs declaration for FTZ enterprises. Foreign WFOEs account for 35% of registered companies in the Shanghai FTZ.
- Guangdong Province Commerce Department (com.gd.gov.cn) — Oversees the Greater Bay Area (大湾区, dà wān qū) sourcing ecosystem, including Shenzhen, Guangzhou, and Dongguan manufacturing hubs. Publishes quarterly regional sourcing compliance circulars.
- Zhejiang Province E-Port (zjport.gov.cn) — Ningbo-Zhoushan port-specific customs procedures, now China’s busiest cargo port by throughput. Key for companies sourcing from the Yangtze River Delta manufacturing belt.
- Hainan Free Trade Port Portal (hainan.gov.cn/htt) — Zero-tariff sourcing for specific industries (medical devices, tourism goods, high-tech components) under the Hainan Free Trade Port Law, with significantly reduced customs inspection rates.
- Jiangsu Customs District (nanjing.customs.gov.cn) — Covers the Kunshan-Suzhou-Wuxi electronics and semiconductor supply chain cluster, with specialized procedures for bonded processing trade (加工贸易, jiāgōng màoyì).
Practical Navigation Tips for Foreign Businesses
- Obtain a digital identity early — Most GACC and MOFCOM portals require a Chinese company digital certificate (数字证书, shùzì zhèngshū) issued by a CNCA-accredited CA. Budget 2–4 weeks to obtain this before the registration process. Cost: approximately RMB 300–800 per certificate annually.
- Use the Single Window for everything customs-related — GACC’s single window consolidates 45+ distinct customs procedures into one login. Avoid using individual port-level portals for standard customs declarations; they are slower and less reliable for everyday operations.
- Check GSXT before signing any supplier contract — The Enterprise Credit Information Publicity System (gsxt.gov.cn) is free and publicly accessible. Search by supplier name (Chinese characters required) to see their registration status, capital, annual filings, and any administrative penalties from SAMR. Approximately 12% of Chinese factories had regulatory penalties recorded on GSXT in 2024.
- Monitor the Negative List annually — MOFCOM publishes the revised Negative List every June/July. The 2025 edition reduced restricted foreign investment from 31 to 28 categories, but added 3 new sector-specific sourcing restrictions in the semiconductor and data center industries.
- Use a licensed customs broker for Single Window navigation — Under GACC regulations, all foreign companies without a China-registered WFOE must use a licensed customs broker (报关行, bàoguān háng) for Single Window declarations. Broker fees: RMB 300–800 per declaration.
- Set up portal alert subscriptions — Most central government portals offer WeChat account integrations or RSS-style push notifications. Subscribe to GACC, MOFCOM, and SAMR updates for your product category to stay ahead of regulatory changes that affect your sourcing compliance.
Legal Framework: Key Laws Behind the Portals
Each government portal implements specific provisions of Chinese law. The PRC Customs Law (海关法), most recently amended in 2021, establishes the legal basis for GACC’s customs supervision, tariff collection, and inspection powers. Articles 23 and 54 cover customs declaration obligations and duty calculation. Articles 82–86 detail smuggling penalties that can reach RMB 500,000 plus confiscation of goods.
The PRC Foreign Trade Law (对外贸易法) Article 15 empowers MOFCOM to impose import/export licensing requirements. The 2022 amendment introduced stronger provisions for trade remedy investigations. Under the PRC Export Control Law (出口管制法, enacted 2020), MOFCOM and GACC jointly manage the dual-use item export control list — companies sourcing items that could have military applications must register on both the MOFCOM and GACC portals and maintain transaction records for at least 5 years (Export Control Law Article 12).
GACC’s 2025 enforcement statistics show that customs audits identified compliance violations in 18.7% of foreign-invested enterprise import declarations, with penalties averaging RMB 52,000 per violation. The most common violations were incorrect HS code classification (43% of cases), undervaluation (28%), and missing or incorrect certificates of origin (15%).
