Dangerous Goods and Special Cargo Sea Freight from China to Europe (2026)

DG sea freight China to Europe: IMDG class overview

The International Maritime Dangerous Goods (IMDG) Code, published by the International Maritime Organization (IMO), is the global standard for shipping dangerous goods by sea. It is mandatory for all signatory states, including China and all EU member states. The code is updated every two years; the current edition is Amendment 42-24, effective from 2026.

Every DG sea freight shipment from China to Europe starts with correct IMDG classification. The shipper is legally responsible for declaring the correct UN number, proper shipping name, class, and packing group. Misdeclaration is the most common cause of container fires, vessel rejections, and customs penalties. Here is the complete class breakdown:

Classes 1 (explosives) and 7 (radioactive material) are the most restricted and require specialized carriers with specific vessel certifications. The majority of China-Europe DG shipments fall into classes 3 (flammable liquids such as paints, solvents, and resins), 8 (corrosives like industrial cleaning agents), and 9 (lithium batteries, UN3536 energy storage systems, and environmentally hazardous substances).

Every DG shipment from Qingdao, Shanghai, or any Chinese port must clear maritime DG declaration (known in Chinese as "危申报" or "海事危险货物申报") before vessel loading. This is separate from customs declaration and is filed with the Maritime Safety Administration (MSA). The declaration package includes:

• DG Packaging Certificate: Issued by a certified inspection body confirming the packaging meets the required UN performance standard for the specific DG class and packing group. This is the document Chinese shippers call "危包证" (wibaozheng). Great Hensen can arrange this in 3 working days for standard DG classes.
• MSDS (Material Safety Data Sheet): A 16-section document detailing the substance's physical and chemical properties, hazards, handling procedures, and emergency response. Must be dated within the last 3 years and match the actual cargo composition.
• Maritime DG Declaration Form: Filed with the MSA at the departure port, listing UN number, class, packing group, flash point (for Class 3), marine pollutant status, and stowage requirements.
• Carrier DG Approval: Each carrier reviews the DG documentation and issues a DG acceptance letter before the booking is confirmed. Without this, the container will not be loaded.

According to market analysis of the global DG logistics sector, the dangerous goods logistics market is projected to reach USD 479.74 billion by 2035 at a 6.45% CAGR, with Asia-Pacific holding 43% of that market. Lithium battery and flammable liquid transport are the two largest growth drivers.

Lithium batteries and energy storage systems to Europe (UN3536/UN3480/UN3481)

Lithium battery shipments from China to Europe have grown sharply alongside Europe's energy transition. The EU Battery Regulation (Regulation (EU) 2023/1542), fully in force as of 2024 with phased requirements through 2027, mandates carbon footprint declarations, recycled content minimums, and CE compliance for all batteries placed on the EU market. This regulation directly affects every lithium battery shipment entering the EU from China.

UN numbers for lithium battery sea freight

UN3536: energy storage container logistics

UN3536 is the most operationally significant UN number for the energy storage industry. Introduced in the 2018 edition of the IMDG Code (Amendment 39-18), it allows lithium batteries permanently installed in a cargo transport unit (such as a 20ft or 40ft containerized BESS) to ship under a single UN number designation rather than requiring separate declarations for each battery module. This simplified framework has been a key enabler of China's rapid growth in BESS exports to Europe.

Great Hensen has shipped more than 1,000 TEU of UN3536 energy storage systems, according to operational records from our UN3536 energy storage case study. The typical shipment flow for a UN3536 BESS container from China to Europe is:

1. Manufacturer provides battery cell UN38.3 test reports and module-level safety certifications
2. DG Packaging Certificate issued for the complete cargo transport unit (not individual battery modules)
3. MSDS prepared covering the lithium-ion chemistry of the installed battery system
4. Maritime DG declaration filed with MSA at the departure port (Qingdao, Shanghai, or Ningbo)
5. Carrier DG approval obtained; major EU-line carriers including Maersk, MSC, COSCO accept UN3536 with advance booking
6. Container loaded under DG supervision; temperature monitoring device placed inside if required by carrier
7. Sea transit via Cape of Good Hope route: 38-55 days from Chinese port to Rotterdam or Antwerp
8. EU customs clearance with battery regulation compliance documentation; CE marking verification at destination

For detailed technical guidance on UN3536 logistics, see our UN3536 energy storage logistics guide. For context on the battery logistics certification landscape, read our analysis of lithium battery logistics professionalization.

Used machinery and CCIC pre-shipment inspection

Used machinery exports from China to Europe involve two overlapping compliance frameworks: Chinese export regulations and EU import requirements. On the Chinese side, the key regulation is the Measures for the Administration of Import and Export of Mechanical and Electrical Products, enforced by the Ministry of Commerce (MOFCOM) and China Customs. Used machinery is defined as equipment that has been in operation (not brand new) and includes pre-owned manufacturing lines, refurbished equipment, and second-hand industrial machinery.

The CCIC pre-shipment inspection process

CCIC (中国检验认证集团) is the government-authorized inspection body for used machinery exports. The inspection verifies:

• Equipment matches the description and specifications in the export application
• Equipment is in functional condition and safe for transport
• Equipment does not contain prohibited hazardous materials (asbestos, PCBs, ozone-depleting substances)
• Electrical safety compliance (voltage, grounding, insulation)
• Proper cleaning and decontamination for equipment that previously handled chemicals, oils, or hazardous materials

The standard process timeline is 10-15 working days from application to CCIC certificate issuance. Expedited processing (5-7 working days) is available for an additional fee. CCIC inspection must be completed before the equipment is packed for export; inspectors need to see the equipment in its operating location.

Once CCIC clearance is obtained, the exporter files the Used Mechanical and Electrical Product Registration with MOFCOM's online system. The full document package for Chinese customs includes:

• CCIC Pre-Shipment Inspection Certificate
• Used Mechanical and Electrical Product Registration Certificate (MOFCOM)
• Commercial invoice and packing list with "USED" designation on each line item
• Equipment specification sheets and original purchase documentation (if available)
• Decontamination certificate (for equipment that handled chemicals, oils, or food products)

For the EU import side, used machinery must comply with the Machinery Directive (2006/42/EC) and carry CE marking if manufactured after 1995. Equipment older than the directive's effective date may require a notified body assessment. Additionally, CBAM reporting obligations apply if the machinery contains steel or aluminum components above the de minimis threshold, though the primary CBAM scope targets raw materials, not finished machinery.

For complete logistics examples of used machinery exports, see our used machinery CCIC export case study. For heavy equipment that is also oversized, our heavy equipment flat rack case study covers the combined challenges of used machinery compliance and OOG handling.

OOG and breakbulk cargo to Europe

Standard 40ft containers have internal dimensions of approximately 12.03m x 2.35m x 2.39m (L x W x H) with a maximum payload of roughly 26-28 tons depending on the container type. Cargo that exceeds any of these dimensions or weight limits is classified as OOG (Out of Gauge). For the China-Europe trade lane, OOG and breakbulk cargo includes heavy machinery, industrial boilers, wind turbine components, construction equipment, and large manufacturing line modules.

OOG equipment types

Lashing plan and securing scheme

Every OOG or breakbulk shipment requires a lashing plan (加固方案) certified by a qualified professional before the carrier will accept the booking. The lashing plan specifies:

• Lashing points on the flat rack or vessel deck
• Type and quantity of lashing equipment (chains, wire ropes, webbing straps, turnbuckles)
• Calculated lashing forces based on vessel motion (pitch, roll, heave) per the IMO CSS Code (Code of Safe Practice for Cargo Stowage and Securing)
• Angle and tension specifications for each lashing point
• Dunnage material placement to distribute weight and prevent point loading

Great Hensen prepares lashing plans for all OOG shipments. The plan is reviewed by the carrier's cargo superintendent and the vessel's chief officer before loading approval. On the China-Europe Cape route, vessels experience Southern Ocean swell conditions off South Africa that subject deck cargo to significant rolling forces; the lashing plan must account for these conditions.

Weight limits and port capabilities

Not all Chinese ports have the same OOG handling capability. Here is the comparison for the key China-Europe departure ports:

For the largest breakbulk shipments exceeding 45 tons single-piece weight, Qingdao and Shanghai are the primary gateway ports. Great Hensen is based 5km from Qingdao Qianwan Container Terminal and maintains daily contact with terminal operations for real-time heavy-lift berth scheduling. For heavy-lift and project cargo services, see our heavy-lift project cargo service page.

EU regulatory compliance for Chinese exports: CE marking, REACH, battery regulation, CBAM

ICS2: Entry Summary Declaration

The Import Control System 2 (ICS2) is now fully operational for all modes of transport, including maritime. Every shipment entering the EU customs territory requires an Entry Summary Declaration (ENS) filed electronically before the goods are loaded onto the vessel at the Chinese departure port. As of 2026, the ENS late-filing penalty has increased from EUR 1,000 to EUR 2,500 per violation.

The ENS must include a detailed cargo description with the 6-digit HS code, consignor and consignee EORI numbers, and the container number. Generic descriptions such as "general cargo" or "freight of all kinds" are rejected. The new EU Customs Code (UCC 2026) further requires full HS code traceability through the supply chain, meaning the HS code declared at export must match the EU import declaration.

CE marking

CE marking is mandatory for products placed on the EU market that fall under one or more EU harmonization directives. For the logistics context, this means the importer of record is responsible for ensuring the products carry valid CE marking documentation before customs clearance. Common regulated categories arriving from China include electrical and electronic equipment (LVD and EMC Directives), machinery (Machinery Directive 2006/42/EC), personal protective equipment (PPE Regulation (EU) 2016/425), and medical devices (MDR (EU) 2017/745).

If a shipment contains products requiring CE marking and the importer cannot produce the Declaration of Conformity (DoC) at the time of customs clearance, the goods may be held, returned, or destroyed at the importer's expense.

REACH regulation

REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals, Regulation (EC) 1907/2006) applies to chemical substances manufactured in or imported into the EU in quantities above 1 ton per year. For Chinese exporters of chemicals, including those shipping DG cargo from China to Europe, REACH means:

• Only EU-based entities (importers or Only Representatives) can register substances under REACH. The Chinese exporter cannot register directly.
• Substances of Very High Concern (SVHCs) are subject to authorization and may be restricted or banned. The SVHC candidate list is updated twice yearly by the European Chemicals Agency (ECHA).
• Safety Data Sheets (SDS) for chemicals shipped to the EU must comply with REACH Annex II format, which differs from the Chinese GB/T 16483 standard. An MSDS prepared for Chinese maritime declaration does not automatically meet EU REACH SDS requirements.

EU Battery Regulation

The EU Battery Regulation (Regulation (EU) 2023/1542) replaced the previous Battery Directive and introduces legally binding requirements phased in from 2024 through 2027. For Chinese battery and BESS exporters, the relevant requirements as of July 2026 are:

• Carbon footprint declaration: Mandatory for EV batteries and industrial batteries above 2 kWh. A carbon footprint calculation following the EU Product Environmental Footprint (PEF) methodology must accompany the shipment.
• CE marking: All batteries placed on the EU market must carry CE marking with the notified body number.
• Due diligence policy: Economic operators placing batteries on the EU market must establish and implement a battery due diligence policy covering raw material supply chains (cobalt, natural graphite, lithium, nickel).
• Digital battery passport: From February 2027, LMT batteries, industrial batteries above 2 kWh, and EV batteries require a digital battery passport accessible via QR code. The data requirements are being finalized but will include the carbon footprint, recycled content percentage, and supply chain due diligence information.

CBAM: Carbon Border Adjustment Mechanism

The EU Carbon Border Adjustment Mechanism (CBAM, Regulation (EU) 2023/956) entered its transitional phase on October 1, 2023, and fully entered into force from January 1, 2026. CBAM currently applies to imports of cement, iron and steel, aluminum, fertilizers, electricity, and hydrogen. For each CBAM-covered product imported, the EU importer must report the embedded direct and indirect emissions and, from 2026, purchase CBAM certificates corresponding to the declared emissions.

In practice, this primarily affects Chinese steel and aluminum exports shipped as raw materials or semi-finished products. Finished machinery and equipment containing steel or aluminum components are generally not in scope for CBAM reporting obligations, though the scope is expected to expand to downstream products from 2028.

Carrier DG acceptance: which carriers accept what

The China-Europe container shipping market as of July 2026 is structured around three major carrier alliances plus the independent MSC:

How carrier DG acceptance works in practice

Carrier DG acceptance is not a simple yes/no question. Each carrier maintains an internal DG acceptance matrix that maps specific UN numbers and packing groups to vessel stowage categories. The key variables are:

• UN number and class: Some carriers accept Class 3 (flammable liquids) broadly but restrict specific UN numbers with low flash points. Class 5.2 (organic peroxides) generally has the tightest acceptance windows.
• Packing group: PG I (high danger) is more restricted than PG II or III. Some carriers require PG I DG cargo to be booked 14 days in advance with additional approval layers.
• Stowage category: The IMDG Code assigns each UN number a stowage category (A through E) specifying where on the vessel the cargo can be placed. On-deck stowage (category A) is generally easier to obtain than under-deck stowage.
• Vessel capacity: Each vessel has a maximum DG capacity by class, typically expressed as a percentage of total TEU slots. When the DG allocation for a specific class on a specific sailing is full, the carrier will refuse additional bookings regardless of other factors.
• Booking window: Most carriers require DG bookings 7-14 days before the vessel's estimated time of departure (ETD). Last-minute DG bookings are almost never accepted.

According to industry reports on CMA CGM's DG suspension, the carrier published expanded DG acceptance restrictions covering 13 countries in 2026, reflecting the industry trend toward more conservative DG acceptance policies following a series of container ship fires attributed to misdeclared DG cargo. Misdeclaration remains the single largest risk factor; carriers increasingly use third-party DG screening services to verify cargo classifications before loading.

Qingdao DG port advantages

Qingdao Port has dedicated DG container storage yards with class-segregated stacking areas, a feature not available at all Chinese ports. For shippers in Shandong, Hebei, and Henan provinces exporting DG cargo to Europe, routing through Qingdao eliminates the domestic trucking leg to Shanghai (approximately 700km each way), saving $200-400 per container and reducing DG cargo road transit time. Great Hensen's office is 5km from Qingdao Qianwan Container Terminal, enabling same-day DG document submission and real-time carrier coordination.

For rate and market conditions, see our July 2026 Europe shipping rates analysis.

FAQ: special cargo to Europe

What documents do I need for DG sea freight from China to Europe?

The complete DG document package includes: MSDS (Material Safety Data Sheet) dated within 3 years, DG Packaging Certificate (危包证), maritime DG declaration filed with MSA at the Chinese departure port, carrier DG approval letter, commercial invoice, packing list with DG annotations, and the bill of lading with DG endorsements. For EU import, add: ICS2 ENS filing confirmation, CE Declaration of Conformity (if applicable), REACH registration or Only Representative confirmation (for chemicals), and EU Battery Regulation compliance documentation (for lithium batteries). The maritime DG declaration is entirely separate from the customs declaration and must be filed 24-48 hours before vessel loading.

Can I ship DG cargo and non-DG cargo in the same container?

Generally no, unless the non-DG cargo is specifically permitted by the IMDG Code segregation table for the DG class involved. Most carriers prohibit mixed DG/non-DG consolidation in a single container to eliminate segregation conflict risks. For LCL DG shipments, the consolidation warehouse must have DG storage certification, and DG cargo must be segregated from other cargo by class compatibility. The safest approach is to ship DG cargo in dedicated containers, which also simplifies both the Chinese maritime declaration and EU import customs clearance.

What is the DG Packaging Certificate and how long does it take?

The DG Packaging Certificate (危包证, wibaozheng) is a Chinese-issued certification confirming that the packaging used for a specific DG shipment meets the UN performance standards required by the IMDG Code. It is issued by a certified inspection body authorized by the General Administration of Customs of China. Standard processing is 5-7 working days; Great Hensen provides expedited 3-working-day processing through established relationships with certified inspection agencies in Qingdao. The certificate is shipment-specific and tied to the manufacturer, packaging type, and DG class. A new certificate is required for each distinct shipment configuration.

How are DG freight rates calculated for the China-Europe route?

DG sea freight rates from China to Europe are calculated as the base ocean freight rate plus DG surcharges. DG surcharges typically add $150-500 per container depending on class, with Class 1 (explosives) and Class 7 (radioactive) carrying the highest premiums. Additional cost factors include: DG documentation fee, DG container inspection fee at origin, DG storage yard fee (if container is held at port DG yard), and EU destination DG handling charges at the terminal. OOG shipments incur flat rack equipment fees ($300-800 premium over standard container rates) plus lashing plan certification and on-site supervision costs. For current Europe freight rate levels, see our July 2026 Europe rate analysis.

What happens if my DG cargo is misdeclared?

DG misdeclaration is the most serious compliance violation in container shipping. Consequences include: immediate vessel rejection and container return to shipper at shipper's expense, carrier-imposed fines (typically $10,000-50,000 per container), placement on carrier blacklists preventing future bookings with that carrier, Chinese MSA administrative penalties, EU customs enforcement action upon arrival, and criminal liability if the misdeclaration results in a fire, spill, or injury. The IMO and major carriers have increased DG screening and enforcement since 2022 following several high-profile container ship fires. Never attempt to ship undeclared DG cargo; the financial and legal risk far exceeds any potential savings.

Can I ship Class 1 (explosives) or Class 7 (radioactive) cargo from China to Europe?

Class 1 and Class 7 shipments require specialized carriers with specific vessel certifications and port clearances that differ from standard container shipping. For Class 1, only vessels with ammunition/explosives carriage certification and approved stowage plans can accept the cargo, and the departure and arrival ports must have designated explosives handling zones (not all ports do). For Class 7, specialized Type A or Type B packaging is required depending on the activity level, and both the Chinese departure port and EU destination port must be licensed for radioactive material handling. These shipments are handled as special projects, not standard DG bookings. Contact our DG team directly for a project-specific assessment if you need to ship Class 1 or Class 7 cargo.
