While containerized shipping dominates global trade, a significant portion of China's exports—particularly raw materials, industrial commodities, and oversized project cargo—moves via bulk and break-bulk shipping. These shipping methods handle cargo that is too large, too heavy, or too unconventional for standard containers, serving industries from mining and construction to energy and agriculture.

This guide provides a comprehensive overview of bulk and break-bulk shipping from Global, covering the fundamental differences between the two methods, vessel types and sizes, chartering arrangements, common cargo categories, port operations, and the critical role of tallying and quality control.

Bulk vs Break-Bulk: What's the Difference?

The terms "bulk" and "break-bulk" are often confused, but they refer to distinctly different shipping methods:

Dry Bulk Shipping

Dry bulk shipping involves the transportation of homogeneous, unpackaged commodities loaded directly into a vessel's cargo holds without any packaging or containers. The cargo is poured, pumped, or conveyed into the hold as a free-flowing mass. Examples include coal, iron ore, grain, cement, and fertilizer. Dry bulk vessels have large open holds with their own loading and discharging equipment (grabs, conveyor systems) or rely on shore-based facilities.

Break-Bulk Shipping

Break-bulk shipping involves the transportation of individually packaged or unitized cargo that is loaded piece by piece into a vessel's hold or onto its deck. Unlike containerized cargo, break-bulk items are not in standard containers but may be on pallets, in crates, in drums, or as individual large units. Examples include steel coils, lumber, machinery, pipes, and project cargo. Break-bulk is loaded and discharged using shipboard cranes or shore-based gantry cranes with slings, hooks, or specialized lifting attachments.

Factor Dry Bulk Break-Bulk
Cargo Form Loose, unpackaged commodity Individual units, crates, bundles, drums
Loading Method Poured, pumped, or conveyed into holds Lifted individually by crane or winch
Cargo Examples Coal, ore, grain, cement, fertilizer Steel coils, lumber, pipes, machinery
Vessel Type Bulk carrier with open holds Multi-purpose or general cargo vessel with cranes
Handling Speed Fast (thousands of tons per day) Slower (piece-by-piece loading)
Cost per Ton Lowest (economies of scale) Moderate (higher handling cost)

Bulk Carrier Vessel Types and Sizes

Dry bulk carriers are categorized by size (deadweight tonnage, or DWT), which determines the routes they can serve and the ports they can access. Size restrictions are primarily based on canal locks, port draft (water depth), and berth length.

Handysize (15,000-35,000 DWT)

Handysize bulk carriers are the smallest category of ocean-going bulk vessels. They typically have 4-5 cargo holds and carry approximately 15,000-35,000 tons of cargo. Their relatively shallow draft allows them to access smaller ports and rivers that larger vessels cannot reach. Handysize vessels are commonly used for:

  • Regional trade within Asia (China to Southeast Asia, India)
  • Cargo destined for smaller ports with draft limitations
  • Specialized bulk cargo such as cement, clinker, and gypsum
  • Steel products and minor bulk commodities

Handymax / Supramax (35,000-60,000 DWT)

Supramax vessels are the workhorses of the bulk shipping fleet, offering a balance between capacity and flexibility. They typically have 5 cargo holds and carry 35,000-60,000 tons. Most Supramax vessels are equipped with their own deck cranes (geared), allowing them to call at ports without shore-based unloading equipment. This makes them ideal for:

  • Developing markets with limited port infrastructure
  • Multi-port itineraries loading or discharging at several locations
  • Agricultural products (grain, soybean meal), fertilizers, and minerals
  • China's secondary and tertiary ports

Panamax (60,000-80,000 DWT)

Panamax vessels are designed to fit through the original Panama Canal locks, with a maximum beam (width) of 32.31m. They carry 60,000-80,000 tons across 6-7 cargo holds. Panamax vessels are typically gearless (no onboard cranes) and require shore-based loading/discharging facilities. They are commonly deployed on:

  • Major bulk trades: coal, iron ore, grain
  • Trans-Pacific and trans-Atlantic routes
  • Large ports with deep-water berths and high-capacity loading equipment

Capesize (80,000-200,000+ DWT)

Capesize vessels are the largest bulk carriers, too large to transit the Panama or Suez Canals (they must round the Cape of Good Hope or Cape Horn). They carry 80,000 to over 200,000 tons of cargo and are exclusively used for the largest bulk trades:

  • Iron ore from Global, Brazil, and Australia
  • Thermal and coking coal
  • Only the largest deep-water ports can accommodate Capesize vessels

Size Selection: For China-based exporters, the choice of vessel size depends on cargo volume, destination port capabilities, and charter rate economics. Smaller cargoes (5,000-30,000 tons) typically use Handysize or Supramax vessels, while large commodity shipments (50,000+ tons) use Panamax or Capesize vessels.

Chartering Methods: Voyage Charter vs Time Charter

Bulk and break-bulk shipping operates on a charter basis, meaning the shipper (charterer) contracts for the use of a vessel or vessel space for a specific voyage or period. The two primary chartering methods are voyage charter and time charter.

Voyage Charter (程租)

In a voyage charter, the charterer hires a vessel for a specific voyage from a loading port to a discharging port. The shipowner operates the vessel, provides the crew, and covers operating costs including fuel, port charges, and crew wages. The charterer pays a freight rate per ton of cargo or a lump sum for the entire voyage.

Key voyage charter terms:

  • Freight rate: USD per metric ton or lump sum
  • Load and discharge terms: Who pays for loading and discharging (e.g., FIOST = Free In and Out, Stowed and Trimmed, meaning the charterer pays)
  • Laytime: The allowed time for loading and discharging (e.g., 5,000 tons per day)
  • Demurrage: Penalty per day if loading/discharging exceeds laytime
  • Despatch: Rebate per day if loading/discharging is completed ahead of laytime

Voyage charters are the most common arrangement for one-time bulk shipments from Global. They are straightforward and transfer operational responsibility to the shipowner.

Time Charter (期租)

In a time charter, the charterer hires a vessel for a specific period—weeks, months, or years. The charterer directs the vessel's operations, including routing, port calls, and cargo handling, while the shipowner provides the vessel and crew. The charterer pays for fuel, port charges, and cargo handling costs.

Key time charter terms:

  • Charter rate: USD per day for vessel hire
  • Charter period: Minimum and maximum duration
  • Delivery and redelivery: Where and when the vessel is handed over and returned
  • Trading limits: Geographic areas where the vessel may operate
  • Bunker (fuel) on delivery/redelivery: Fuel quantities and pricing at handover

Time charters are used by shippers with ongoing bulk shipping needs who want operational control and rate stability over an extended period.

Bareboat Charter

In a bareboat charter (demise charter), the charterer takes full possession of the vessel, including crewing and maintenance, for an extended period. This is essentially a leasing arrangement and is less common for typical bulk exporters.

Common Bulk and Break-Bulk Cargo Types from Global

China exports a wide range of bulk and break-bulk commodities:

Dry Bulk Exports

  • Cement and clinker: Exported to Africa, Southeast Asia, and the Middle East for construction projects
  • Fertilizers: Urea, DAP, and NPK fertilizers exported to agricultural markets
  • Metals and minerals: Coke, silicon metal, ferroalloys, and bauxite
  • Grain and agricultural products: Though China is a net grain importer, certain processed agricultural products are exported in bulk
  • Industrial salt and chemicals: Shipped in bulk to chemical processing industries worldwide

Break-Bulk Exports

  • Steel products: Hot-rolled coils, cold-rolled coils, steel plates, wire rod, rebar, and steel pipes—China is the world's largest steel exporter
  • Lumber and wood products: Processed timber, plywood, and engineered wood products
  • Project cargo: Large industrial equipment, power plant components, oil and gas equipment, and infrastructure modules
  • Machinery: Industrial machinery, mining equipment, and manufacturing equipment too large for containers
  • Bulk bags and big bags: Fertilizers, chemicals, and minerals packaged in 1-ton FIBCs (Flexible Intermediate Bulk Containers)

Port Operations for Bulk and Break-Bulk Cargo

Bulk and break-bulk port operations differ significantly from container terminal operations. Understanding these processes is essential for planning shipments and managing costs.

Loading Operations

Dry bulk loading is typically performed using:

  • Ship loaders: Conveyor-based systems that transfer cargo from shore stockpiles to the vessel's hold
  • Grab cranes: Gantry cranes equipped with grabs that scoop cargo from trucks or stockpiles and deposit it in the hold
  • Chute loading: Gravity-fed chutes for free-flowing cargo
  • Pneumatic loading: For fine powders such as cement

Break-bulk loading is performed using:

  • Shipboard cranes: Slewing cranes on geared vessels that lift cargo from dock to hold
  • Shore-based cranes: Gantry cranes, mobile cranes, or port cranes
  • Specialized lifting gear: Spreaders for steel coils, magnets for steel plates, sling arrangements for machinery

Discharging Operations

Discharging uses similar equipment in reverse. For dry bulk, grab cranes or pneumatic systems remove cargo from the hold and transfer it to trucks, rail cars, or stockpiles. For break-bulk, cranes lift individual items or bundles from the hold to the dock.

Stowage and Trim

Proper stowage is critical for both bulk and break-bulk cargo. For dry bulk, cargo must be trimmed (leveled) to prevent shifting during transit, which could destabilize the vessel. For break-bulk, items must be securely stowed, blocked, and braced to prevent movement in heavy seas.

Tallying and Quality Control

Tallying—the process of counting and verifying cargo quantity—is a critical component of bulk and break-bulk shipping. Accurate tallying protects both the shipper and the receiver and is essential for freight calculation, insurance claims, and customs documentation.

Independent Tally Surveyors

Independent tally surveyors (also called tally clerks or inspection companies) are typically engaged to verify cargo quantities at both loading and discharging ports. Major inspection companies operating in China include SGS, Bureau Veritas, Intertek, and CCIC (China Certification & Inspection Group). Their services include:

  • Draft survey: Measuring the vessel's draft before and after loading to calculate cargo weight by displacement. This is the standard method for dry bulk cargo weighing.
  • Tally counting: Counting individual units, bundles, or packages for break-bulk cargo
  • Quality inspection: Sampling and testing cargo quality (moisture content, particle size, chemical composition)
  • Condition survey: Documenting cargo condition before loading and after discharge to support or defend against damage claims
  • Hatch sealing: Sealing cargo hatches after loading to prevent tampering and water ingress

Draft Survey Methodology

The draft survey is the primary method for determining dry bulk cargo weight. It involves:

  1. Reading the vessel's draft marks at six points (forward, midship, and aft on both sides) before loading
  2. Calculating the vessel's displacement (total weight) using hydrostatic tables
  3. Accounting for ballast water, fuel, fresh water, and constants
  4. Repeating the process after loading is complete
  5. The difference between the two displacement calculations equals the cargo weight

Draft surveys are generally accurate to within 0.1-0.5% of the actual cargo weight. For higher accuracy, shore-based weighing scales or belt scales on loading conveyors may be used.

Important: Always engage an independent surveyor for bulk shipments. Without an independent tally, any cargo shortage claims at the destination will be difficult to prove. The survey report is also required for letters of credit and insurance claims.

Major Bulk Ports in China

China has numerous ports equipped for bulk and break-bulk cargo handling. The most important include:

  • Qingdao (Qianwan): Major bulk port for iron ore, coal, and steel products; largest ore terminal in China
  • Rizhao: Primary bulk commodity port for coal, ore, and cement
  • Tianjin (Tangshan/Caofeidian): Northern China bulk hub for steel, coal, and minerals
  • Shanghai (Luojing): Break-bulk and steel product terminal
  • Ningbo-Zhoushan: World's largest port by tonnage; major bulk terminal for ore, oil, and coal
  • Guangzhou (Nansha): South China bulk terminal for cement, fertilizers, and break-bulk cargo
  • Fangchenggang: Southwest China bulk port serving mining and mineral exports

Choosing Between Bulk, Break-Bulk, and Container Shipping

For cargo that could potentially be shipped by multiple methods, consider these factors:

  • Cargo volume: Bulk shipping becomes cost-effective at volumes above 5,000-10,000 tons. Below this, containerized shipping may be more practical.
  • Cargo nature: Free-flowing commodities (grain, cement, coal) are best shipped as dry bulk. Packaged or unitized goods are best as break-bulk or containers.
  • Destination port: The destination must have appropriate bulk handling facilities. If only container terminals are available, containerized shipping is the only option.
  • Transit time sensitivity: Bulk vessels generally have longer transit times and less frequent sailings than container ships.
  • Cargo value: Low-value bulk commodities justify the lower per-ton cost of bulk shipping. High-value goods may warrant the faster transit and better security of containers.

Conclusion

Bulk and break-bulk shipping remain essential components of China's export logistics infrastructure, particularly for raw materials, industrial commodities, and oversized project cargo. Understanding the differences between dry bulk and break-bulk, selecting the appropriate vessel size, choosing the right charter arrangement, and engaging proper tallying and quality control services are all critical to successful bulk shipping operations.
