Cargo That Cannot Be Consolidated

What Are Cargoes That Cannot Be Co-loaded?

Cargoes that cannot be co-loaded refer to those LCL cargoes that are difficult to safely and appropriately consolidate into the same container with cargoes from other shippers.

In LCL co-loading, cargoes from multiple shippers are gathered at a CFS and consolidated into one container according to the destination, vessel, and connecting schedule. Therefore, depending on factors such as cargo hazard, shape, weight, odor, leakage, temperature conditions, packing status, or theft risk, the CFS, NVOCC, co-loader, or shipping line may refuse to accept the cargo.

However, cargo that cannot be co-loaded does not necessarily mean cargo that cannot be transported internationally at all. It includes cargo that is generally difficult to accept in normal LCL co-loading, cargo requiring prior approval or additional documentation, cargo needing dedicated services such as dangerous goods LCL handling, as well as cargo for which switching to FCL, air transport, or dedicated shipment should be considered.

Whether cargo can be co-loaded cannot be determined by the cargo name alone. Even with the same product name, acceptance can vary depending on factors such as composition, quantity, packing, unit weight, dimensions, temperature conditions, dangerous goods classification, destination, and the CFS used.

Why Are Some Cargoes Not Allowed for Co-loading?

In LCL co-loading, cargoes from multiple shippers are loaded into the same container. Leakage, odor, heat generation, corrosion, contamination, or cargo collapse originating from one cargo may cause damage to other shippers' cargo within the container.

CFS, NVOCCs, and co-loaders mainly determine acceptance based on the following perspectives.

Evaluation Criteria	Items Checked	Examples Making Acceptance Difficult	Required Measures
Impact on Other Cargo	Odor, liquid leakage, powder leakage, contamination, heat generation, and corrosion	Fragrances, oils, chemicals, powders, or damp cargo	Consider sealed packaging, absorbents, segregation, or FCL.
Operational Safety	Fire, explosion, toxicity, weight, and tipping risk during handling	Dangerous goods, high-center-of-gravity machinery, or extremely heavy items	Obtain dangerous goods approval, arrange special handling, or dedicated transport.
Stackability	Dimensions, individual weight, cargo form, center of gravity, and stackability	Long cargo, cargo prohibited from top stacking, or irregular-shaped cargo	Prepare stowage plans, cargo photos, and obtain CFS approval.
Packing Strength	Ability to withstand multiple handling and maritime transport	Thin cardboard, unpacked cargo, or unsecured machinery	Repack, crate, or palletize cargo.
Laws and Regulations	Dangerous goods, export/import controls, and port-side requirements	Cargo requiring dangerous goods declaration or subject to regulations	Check SDS, declarations, and permits.
Temperature Conditions	Temperature range required during transport and CFS storage	Pharmaceuticals, food, chemicals, or temperature-sensitive cargo	Consider reefer containers, air transport, or temperature-controlled services.
Theft Risk and Value	High value, ease of converting to cash, and need for individual control	Branded goods, electronics, precious parts, or rare items	Consider FCL, air freight, security, sealing, and insurance.
CFS Equipment	Forklift, crane, floor load capacity, and storage capability	Cargo requiring special lifting or large machinery	Select CFS with suitable equipment or specialized service providers.

Difference Between Cargo That Cannot Be Co-loaded and Prohibited Cargo

Category	Basic Meaning	Expected Response	Points to Note
Cargo generally not accepted for LCL	Cargo that does not meet the acceptance criteria of typical co-loading services	Consider separate CFS, dedicated co-load, FCL, or air transportation	May be accepted under other services.
Cargo accepted conditionally	Cargo that can be accepted if prior approval, repacking, or additional documents are provided	Submit SDS, photos, packaging specifications, and approval documents	Booking confirmation alone does not guarantee acceptance.
Cargo accepted only by specific services	Cargo requiring dedicated services such as hazardous LCL or temperature control	Select appropriate service providers and dedicated routes	There are restrictions on applicable UN numbers and temperature ranges.
Cargo prohibited by law or transport conditions	Cargo whose export, import, shipment, or transport is prohibited by law	Cease transportation and verify legal and permit requirements	Distinguished from mere CFS acceptance refusal.

How to Determine if Cargo Is Dangerous Goods

Whether cargo is classified as dangerous goods cannot be determined solely by the product name or the shipper's recognition. As a rule, the composition, physical properties, hazards, and transport conditions of the cargo should be reviewed and classified based on the applicable dangerous goods transport regulations.

For maritime transport, verification is made against the IMDG Code regarding the UN Number, Class, Packing Group, Marine Pollutant status, segregation requirements, packaging, and markings.

However, even if the SDS states that the cargo is "not dangerous goods," not all shipping lines, NVOCCs, or CFS facilities necessarily accept it as usual LCL cargo. Even if the cargo does not fall under legally defined dangerous goods, it can be refused based on the carrier's or other operators' internal acceptance criteria due to odor, leakage, heat generation, contamination potential, or operational safety concerns.

Details on the definition, classification, exemption quantities, limited quantities, declaration, and marking of dangerous goods are covered in specialized articles such as “Dangerous Goods and Co-loaded Cargo.” This article limits its scope to confirmation points necessary for LCL acceptance decisions.

Confirmation Flow When Using Dangerous Goods Co-loading Services

1. Verify the product name, ingredients, intended use, and physical properties.
2. Obtain the latest version of the SDS (Safety Data Sheet).
3. Confirm the UN Number, Class, Packing Group, and Marine Pollutant status.
4. Check the dangerous goods declaration and other required submission documents.
5. Confirm whether the cargo qualifies for the dangerous goods-compatible LCL service.
6. Obtain acceptance approvals from the shipping line, NVOCC, co-loader, and CFS.
7. Verify segregation requirements and prohibitions on co-loading within the same container.
8. Ensure containers, packaging, labels, and markings comply with regulations.
9. Confirm submission deadlines for dangerous goods documents and the CFS in-gate deadline.
10. Document in writing the approval conditions, any additional charges, and alternative arrangements if acceptance is denied.

For dangerous goods, do not assume that “small quantities can be shipped as general cargo.” Even small amounts may require classification, declaration, packaging, labeling, or prior approval as dangerous goods.

Reasons Why Long Cargo and Heavy Cargo Are Unsuitable for Co-loading

For long cargo and heavy cargo, it is necessary to confirm not only whether the cargo can fit inside the container but also whether it can be safely handled within the CFS, whether it can be co-loaded with other cargo, and whether it will impose excessive load on the container floor and the overall stowage.

In particular, cargo with heavy unit weight, small ground contact area, unbalanced center of gravity, requiring lifting, without forklift entry points, or prohibited from stacking is often difficult to accept for LCL shipments.

Check Item	Details to Verify	Required Documentation	Actions if Issues Arise
Overall Dimensions	Length, width, height, and protrusions	Dimension chart, packing diagram, and photos	Consider specialized co-loading or FCL.
Unit Weight	Weight per package	Packing list and weighing results	Confirm handling equipment and floor load capacity.
Center of Gravity	Stability against toppling, cargo collapse, and during lifting	Center of gravity diagram and work instruction sheet	Arrange support stands, secure cargo, or specialized handling.
Forklift Entry	Whether it can be safely handled by forklift	Bottom photos and packing diagram	Add skid or pallet if needed.
Lifting Requirements	Need for crane and lifting gear	Lifting point diagram and weight certification	Select a CFS with appropriate equipment.
Stacking Feasibility	Allowable to stack on top or bottom	Handling marks and packing specifications	Confirm dead space charges or arrange dedicated handling.

Reasons Why Temperature-Controlled Cargo Is Unsuitable for Co-loading

Temperature-controlled cargo must maintain specified temperature conditions not only during transport but also throughout all processes, including after export CFS delivery, while awaiting co-loading, at transshipment ports, at import CFS, and until cargo pick-up.

Standard LCL dry containers cannot maintain different temperature settings for each shipment. Additionally, refrigerated or frozen facilities may not be available during temporary storage at CFS.

For goods such as food, pharmaceuticals, cosmetic raw materials, chemicals, and precision instruments, even brief temperature deviations could cause quality deterioration or make the goods unusable.

For cargo requiring temperature control, it is essential to confirm allowable temperature ranges, permissible deviation times, the need for temperature records, CFS storage conditions, responses to power outages, and insurance conditions. These factors should be compared when considering reefer FCL, temperature-controlled co-loading, air transport, or dedicated services.

Precautions for Odorous Cargo, Liquid Cargo, and Powdered Cargo

Cargo Characteristics	Main Risks	Points to Confirm	Main Countermeasures
Odorous Cargo	Odor transfer to other cargo and residual container odor	Odor intensity, composition, container sealing, and past acceptance records	Sealed packaging, double packaging, dedicated co-loading, or FCL
Liquid Cargo	Container damage, leakage, and contamination of other cargo	Container specifications, inner bags, absorbents, securing methods, and hazardous material classification	Leak-proof packaging, drip trays, absorbents, or FCL
Powdered Cargo	Powder leakage, dispersion, adhesion, and respiratory effects	Particle size, inner bags, sealing condition, and toxicity	Sealed containers, double packaging, or dedicated arrangement
Wet Cargo	Moisture transfer, mold, condensation, and contamination of surrounding cargo	Dryness condition, waterproof packaging, and drainage	Drying, repacking, or separate shipment arrangement

Poorly Packaged Cargo

LCL cargo goes through multiple handling steps such as collection at the export side, CFS in-gate, sorting, vanning, sea transport, import-side devanning, sorting, and delivery.

Cargo with thin corrugated cardboard, simple packaging, loose cargo, unsecured machine parts, cargo without corner protectors, cargo not fixed to pallets, or cargo that cannot withstand stacking may not be suitable for regular LCL co-loading.

Packing Issues	Potential Incidents	Improvement Methods	Verification Documents
Insufficient cardboard strength	Crushing, tearing, and exposure of contents	Reinforced cardboard, wooden crates, or wooden frames	Packing photos and specification sheets
Insufficient pallet securing	Load collapse, falling off, and tipping over	Strapping, stretch wrap, and anti-slip materials	Four-direction photos of completed packing
Lack of corner protectors	Strap indentation and corner damage	Use of corner protectors and additional cushioning materials	Detailed packing photos
Inadequate waterproofing	Water damage, condensation, and mold	Waterproof inner bags, desiccants, and reinforced outer packaging	Packing specifications and storage condition details
Insufficient machinery securing	Internal movement, center of gravity shifts, and damage	Skid securing, bolting, and cushioning	Securing drawings and completed packing photographs
Inadequate handling markings	Upside-down loading, incorrect lifting, or stacking	“This Side Up”, center of gravity, lifting point, and stacking prohibited markings	Photos showing marking locations

High-Value and Theft Risk Cargo

High-value or highly liquid cargo may not be accommodated with individual locking compartments or dedicated surveillance in typical LCL co-loading.

For branded goods, electronic devices, precision instruments, rare parts, and expensive raw materials, it is necessary to check not only the cargo value but also whether the packaging suggests the contents, storage location in the CFS, sealing methods, identity verification at cargo handover, and insurance terms.

When transporting high-value cargo via LCL, the cargo value and item details should be disclosed at the quotation or booking stage, and the contracting carrier’s or insurer’s conditions for high-value cargo, liability limits, and theft exclusion should be confirmed.

Information Required for Prior Confirmation of Co-loading Compatibility

Information to Confirm	Reason for Confirmation	Documents to Prepare	Problems Due to Insufficient Information

Who Confirms What and When

Stage	Main Confirmer	Main Confirmation Contact	Items to Confirm
Before Requesting Quotation	Shipper / Exporter	Internal Staff, Manufacturer, Packer	Description of goods, ingredients, dimensions, weight, temperature, value, and packaging
Before Booking	Shipper / Prime Freight Forwarder	NVOCC, Co-loader, CFS	Whether normal LCL acceptance is possible, required documents, and conditions
At Booking	Prime Freight Forwarder / NVOCC	Shipping Line, CFS, Co-loader	Prior approval, additional charges, in-gate conditions, and alternatives
Before In-gate	Shipper, Domestic Delivery Provider, Customs Broker	Prime Freight Forwarder, CFS	Destination, reception hours, in-gate slip, packaging, and cargo condition
At CFS Acceptance	CFS, Co-loader	Prime Freight Forwarder, Shipper	Actual dimension, actual weight, odor, leakage, labeling, and outer packaging
When Acceptance Is On Hold	Prime Freight Forwarder	CFS, Co-loader, Shipper	Reason for hold, possibility of correction, deadline, and costs
When Acceptance Is Refused	Prime Freight Forwarder, Shipper	Alternate CFS, NVOCC, FCL Carrier, Air Carrier	Drayage, repacking, next vessel, storage, and delivery schedule

Reasons for CFS Refusal Despite Having a Booking

A booking is the procedure to reserve space or transport capacity based on the declared cargo information. The confirmation of a booking does not mean the actual cargo meets the CFS acceptance conditions.

If the dimensions, weight, dangerous goods information, or packaging details declared at booking are insufficient, the cargo may be held or refused upon inspection at the CFS.

Also, even if the prime freight forwarder considers the cargo acceptable, it may be rejected based on the standards of the actual co-loader organizing the co-load, the CFS, or the shipping line.

To ensure acceptance, it is important not only to obtain the booking number but also to clearly specify the cargo conditions and obtain any necessary prior approvals.

Initial Response When Shipment Is Refused at CFS In-Gate

1. Confirm the specific reason why the CFS cannot accept the cargo.
2. Identify issues such as dangerous goods, dimensions, weight, odor, liquid leakage, powder leakage, or packaging defects.
3. Obtain cargo photos, actual measured dimensions, actual weight, CFS comments, and hold records.
4. Check whether the issue can be corrected before the CFS cut-off for the scheduled vessel.
5. Confirm if acceptance is possible through repacking, label correction, adding documents, or reacquiring prior approval.
6. If the same CFS cannot accept the cargo, check alternative CFS facilities or different co-load services.
7. When normal LCL is difficult, compare options such as FCL, dangerous goods LCL, air transport, or dedicated shipments.
8. Confirm costs related to drayage, repacking, storage, cancellation, and next vessel arrangements.
9. Notify importer, customs broker, and delivery destination of any impact on delivery schedules.
10. After reviewing the cause, declared information, and contract conditions, clarify responsibility for additional charges.

In the initial response, prioritize confirming whether the cargo can be loaded onto the scheduled vessel or alternative arrangements can be made, and whether cargo safety and delivery timelines can be ensured, before pursuing any claims for responsibility.

How to Determine Responsibility for Additional Charges Due to Refusal of Acceptance

Even if refusal of acceptance at a CFS results in drayage charges, repacking costs, storage fees, cancellation fees, or costs for the next vessel, it does not always mean that the shipper or freight forwarder must bear these costs.

Responsibility for these costs is determined by factors such as the cause of refusal, who held which information, what was declared at the time of booking, who confirmed that acceptance was possible, and whether the quotation terms and clauses were validly agreed upon.

Main Cause of Refusal of Acceptance	Main Considerations for Cost Responsibility	Documents to Verify	Practical Notes
The shipper did not declare hazards or odors	Whether the shipper withheld critical information despite being aware of it	Quotation requests, SDS, emails, and product documents	Costs may be borne by the shipper, but contract terms should be reviewed.
Declared dimensions/weight differed from the actual cargo	Who prepared the figures and who confirmed them	Packing list, weighing results, and cargo photos	Check the extent of discrepancies and their impact on acceptance decisions.
The prime freight forwarder stated that acceptance was possible without CFS confirmation	Whether acceptance was guaranteed definitively or conditionally	Quotation, booking emails, and records of explanations	Failure by the prime freight forwarder to obtain confirmation may be a key issue.
The co-loader changed the decision after prior approval	Whether the approval conditions matched the actual cargo	Approval emails, photos, SDS, and in-gate records	Verify reasons for decision changes by the co-loader or CFS.
Packing was damaged at the time of CFS in-gate	Whether the damage occurred before in-gate or during inland delivery	Pickup photos, delivery records, and CFS remarks	Separate repacking costs from cargo damage evaluation.
CFS equipment could not handle the cargo	Whether equipment conditions were disclosed in advance	Dimension/weight data, CFS conditions, and approval records	Confirm the basis for bearing drayage costs to specialized CFS.
Shipping line or destination side changed acceptance conditions	Timing of change, timing of notification, and availability of alternatives	Shipping line notifications, booking terms, and communication records	Force majeure changes do not automatically assign costs to one party.

Even if standard trading conditions or B/L clauses include provisions on cost responsibility, exemptions, shipper’s declaration obligations, or reimbursement of actual costs, these do not necessarily apply to all transactions automatically. It is necessary to verify presentation before contract formation, incorporation into quotations, agreement between parties, individual conditions, and mandatory laws.

Acceptance or Rejection from the Perspective of the Freight Forwarder’s Standard Five Classifications

The five classifications in this article are not established by law or industry-wide consensus. They serve as an analytical framework within this series to clarify the scope of freight forwarder involvement.

Just because a forwarder is the shipper’s point of contact does not mean the forwarder guarantees acceptance of the cargo. It is necessary to verify the quotation, booking, House B/L, clauses, delegation contents, and the actual handling.

Standard Five Classifications	Typical Involvement in Co-load Acceptance Decisions	Contractual Position with Shipper	Main Checks When Rejecting Acceptance	Practical Considerations
Simple Intermediary	Relays cargo information to CFS or NVOCC	Does not undertake transport in own name	Whether information was conveyed accurately and whether confirmation results were explained correctly	Even as a simple intermediary, miscommunication or failure to confirm can become issues.
Cargo Transportation Service Provider	Provides cargo transport using other transport operators	May bear liability under a cargo transportation service contract with the shipper	Checks cargo conditions and selects appropriate transport modes	Rejection of acceptance by subcontractors and the forwarder’s contractual liability to the shipper should be handled separately.
NVOCC / House B/L Issuer	Issues House B/L and undertakes transport to the final destination	Highly likely to be the Contracting Carrier in relation to the shipper	Conditions of acceptance, clauses, explanations regarding acceptance or rejection, and alternative arrangements	Amounts recoverable from co-loaders may not match the liability to the shipper.
Door-to-Door Single Contractor	Integrates collection, CFS in-gate, ocean transport, customs clearance, and delivery	Offers multiple stages as a single service	Pre-collection confirmation, packaging, drayage, and delivery schedule coordination	This does not mean unlimited liability for all processes.
Agent/Coordinator for Specific Operations	Coordinates specific operations such as CFS approval, repacking, or alternative transport	Involved only in delegated tasks	Scope of delegation, parties to confirm with, and contents of explanation	The coordinator for specific operations is not necessarily a contracting party for the entire transportation.

Contracting Carrier and Actual Carrier are legal or contractual status concepts and do not replace the standard five classifications used in this article.

Specific physical tasks such as packing, storage, inspection, loading, vanning, devanning, CFS in-gate, or inland delivery do not themselves constitute a sixth classification.

For example, the prime freight forwarder may undertake transport from the shipper as an NVOCC / House B/L Issuer, a co-loader may arrange the actual co-load, and a CFS may make the cargo acceptance decision. It is necessary to separate and organize their contractual positions, involvement under the five classifications, and actual tasks.

Points to Note in Co-loading

In co-loading, the prime freight forwarder who takes the booking from the shipper and the co-loader who actually arranges the consolidated container are different entities.

Even if the prime freight forwarder considers the cargo acceptable, the co-loader or the co-loader’s CFS may reject it based on their own standards.

Check Item	Reason for Confirmation	Main Confirmation Source	Risk if Not Confirmed
Actual Co-loader	To identify who makes the final acceptance decision for co-loading	Prime Freight Forwarder	Uncertainty about whose standards apply for acceptance judgment.
Co-loader’s CFS	To verify facilities, cargo handling, and acceptance criteria	Co-loader	Cargo might be rejected after arrival at the CFS.
Standards for Dangerous Goods, Odors, and Liquids	Because co-loaders generally have their own restrictions even on normally acceptable cargo	Co-loader, CFS	Cargo not classified as dangerous by law may still be refused.
Restrictions on Long or Heavy Cargo	To confirm limitations on co-load stowage and handling equipment	CFS, Co-loader	Requires drayage to another CFS or switching to FCL.
Required Documents and Prior Approvals	To prevent delays or holds at cargo intake	Prime Freight Forwarder, Co-loader	Missing documents may cause the cargo to miss the vessel sailing.
Alternatives if Rejected	To minimize impact on delivery schedule and additional costs	Prime Freight Forwarder, Alternative Providers	Delay in arranging alternatives.

The scope of explanation responsibility to the shipper and handling after refusal of acceptance vary depending on whether the prime freight forwarder merely acts as a Simple Intermediary passing on information or undertakes carriage as an NVOCC / House B/L Issuer.

However, responsibility should not be judged solely by the classification name, but by confirming the quotation terms, House B/L, clause conditions, prior approvals, and actual response practices.

Criteria for Switching to FCL

Decision Criteria	Reason to Consider FCL	Checks Still Required for FCL	Other Alternatives
Causes odor or contamination to other cargo	Easier to separate from other shippers’ cargo	Odor, cleaning, and contamination on container return	Dedicated co-loading or sealed packaging
Risk of liquid leakage	Reduces risk of damage spreading to other shippers’ cargo	Containers, absorbents, securing, and dangerous goods regulations	Reinforced packaging or dedicated transport
Long or heavy cargo	Easier to design loading according to cargo	Container interior dimensions, weight limits, floor loading, and cargo handling	Specialized container or break bulk
Need to manage high-value goods separately	Easier to avoid mixing with other cargo	Seals, insurance, theft prevention, and container storage location	Air transport or security-guarded transport
Packing cannot withstand multiple handlings	May reduce handling frequency compared with LCL	Securing cargo inside the container and loading reinforcement	Repacking or dedicated service
Delivery schedule is critical	May avoid waiting for co-loading and CFS sorting	Vessel space, CY cut-off, and drayage	Air transport or split shipment
Temperature control is required	Can set temperature for the entire reefer container	Temperature setting, power supply, pre-trip inspection, and temperature records	Air transport or temperature-controlled co-loading

Switching to FCL does not solve all issues. Dangerous goods, temperature control, weight limits, cargo securing inside the container, port acceptance conditions, and insurance terms must still be confirmed separately even with FCL.

Common Practical Issues

Common Issue	Main Cause	Reference Documents	Key Points for Assessment	Initial Response
Dangerous goods identified after booking	SDS not submitted or booking made based only on product name	SDS, product documents, and booking records	Check dangerous goods classification and service acceptance criteria.	Suspend the regular LCL booking and obtain dangerous goods approval.
Rejected by CFS due to strong odor	Odor information was not shared at booking	Cargo photos, SDS, CFS comments, and email correspondence	Distinguish regulatory dangerous goods classification from CFS-specific standards.	Consider sealed packaging, alternative CFS, dedicated co-load, or FCL.
Actual measured dimensions exceeded declared dimensions	Declared product dimensions instead of packed dimensions	Packing list, actual measurement records, and photos	Confirm impact on stowage and freight differential.	Issue a revised quotation and consider the next vessel or FCL.
CFS handling impossible due to overweight items	Unit weight information was not shared in advance	Weight tables, equipment conditions, and CFS records	Check availability of suitable handling equipment.	Arrange drayage to a specialized CFS or arrange special handling.
Acceptance on hold due to packaging damage	Damage during inland delivery or insufficient packaging strength	Pickup photos, CFS photos, and delivery records	Confirm timing of damage occurrence and time available for repacking.	Preserve cargo condition and arrange repacking service.
Co-loader suddenly rejected cargo just before acceptance	Lack of confirmation or inconsistent terms between the prime freight forwarder and co-loader	Approval emails, quotation terms, and cargo documents	Confirm who approved which conditions.	Consider an alternative co-loader, FCL, or the next vessel.
Temperature control requirements cannot be met with normal LCL	Temperature cannot be maintained in CFS storage or dry container	Temperature specifications, transport plan, and quality documents	Verify temperature maintenance feasibility for the entire process.	Switch to reefer, air freight, or dedicated service.
High-value cargo requires carrier or insurer approval	No prior declaration of cargo value	Invoice, quotation, and insurance conditions	Separate carrier acceptance restrictions and insurance conditions.	Declare value, obtain insurance, and reconsider transport method.

Common Misconceptions

Misconception	Actual Understanding	Practical Notes
Small cargo can always be shipped as LCL	Even if the cargo is small, it may be rejected due to danger, odor, leakage, weight, or packing.	Submit not only the cargo name but also dimensions, weight, composition, and photos.
Small quantities of dangerous goods can usually be co-loaded	Even small quantities may require classification, declaration, packing, and acceptance approval.	Check UN No., Class, Packing Group, and SDS.
If SDS indicates non-dangerous goods, acceptance is guaranteed	Even if legally non-dangerous, odor, leakage, or company-specific criteria may cause refusal.	Confirm approval from NVOCC, co-loader, and CFS.
If booking is secured, CFS will always accept	Booking is based on declared information and may be held or rejected after actual cargo inspection.	Obtain prior approval with photos if necessary.
If refused by CFS, transport is impossible	Even if LCL is refused, it may still be possible to ship by FCL, dedicated co-load, air freight, or repacking.	Compare alternative transport options early.
Long cargo poses no problem if it fits in a container	CFS handling, loading with other cargoes, center of gravity, and stacking feasibility also matter.	Check dimensions, unit weight, center of gravity, and forklift access.
Switching to FCL eliminates the need for packing	Even with FCL, securing inside the container, preventing cargo shift, and waterproofing are required.	Confirm loading and securing plans.
Additional charges from refusal are always borne by the shipper	Responsibility depends on cause, declaration, prior approval, quotation terms, and confirmation lapses.	Check evidence and contracts before concluding liability.
If the prime freight forwarder accepts, the co-loader will accept too	The actual co-loader or CFS may apply different standards when making decisions.	Confirm with the actual co-loading operator.
Marine cargo insurance covers any issues from unsuitable co-loading	Insurance coverage does not substitute for CFS acceptance or proper packing for safety.	Confirm acceptance conditions, packing, and insurance terms separately.

Specific Example 1: Discovery of Dangerous Goods After Booking

The shipper provided only the product name and quantity to the prime freight forwarder, who obtained the booking as a regular LCL shipment. Subsequently, before CFS in-gate, the submitted SDS revealed that the cargo might be classified as dangerous goods.

In this case, the original LCL booking should not be used as is. Instead, confirm the UN Number, Class, Packing Group, quantity, packaging, and destination.

Even if a dangerous goods-compatible LCL service is available, it is necessary to verify the applicable UN Numbers, segregation requirements, and shipping line approval. If the required documents and dangerous goods CFS cut-off cannot be met, consider the next vessel or FCL shipment.

Responsibility for additional charges should be determined by confirming whether the shipper was aware of the dangerous goods information, whether the prime freight forwarder requested submission of the SDS, and whether the cargo was conclusively accepted as non-dangerous.

Specific Example 2: Refusal of Acceptance at CFS Due to Odor

The cargo was not classified as dangerous goods under applicable laws, but a strong odor was detected upon CFS in-gate, resulting in refusal of acceptance to prevent odor transfer to other cargo.

In this case, being legally non-dangerous is not sufficient to require the CFS to accept the cargo. The CFS or co-loader may establish its own acceptance criteria based on the impact on other shippers’ cargo and residual odor after container return.

The source of the odor, container seal integrity, packaging, possibility of double packaging, and past transport records should be checked. If repacking cannot resolve the issue, dedicated consolidation or FCL shipment should be considered.

If odor information was shared before booking and acceptance was nevertheless confirmed, the approval record should be used to clarify responsibility for drayage charges and other expenses.

Specific Example 3: When the Actual Measured Length of Long Cargo Differs from the Declared Dimension

The shipper declared the length of the product itself, but after wooden-crate packing, the overall length significantly exceeded the declared dimension. The CFS therefore determined that regular co-loading was difficult.

For co-loading eligibility, the final exterior dimensions and individual weight after packing are used, not the product dimensions. Actual measurements must include protrusions, wooden crates, pallets, and lifting fittings.

If sufficient time remains before the scheduled vessel departure, alternative loading methods or special co-loading arrangements should be checked. If these options are not possible, switching to FCL, a different CFS, or the next vessel should be considered.

For drayage charges or freight differences, confirm who prepared the dimension information and whether the prime freight forwarder requested verification of the post-packing dimensions.

Specific Example 4: When the Prime Freight Forwarder and Co-loader Have Different Judgments

The prime freight forwarder judged that LCL acceptance was generally possible based on past handling experience, but the co-loader’s CFS selected for the shipment prohibited acceptance of liquid cargo.

In this case, it is necessary to confirm not only the prime freight forwarder’s general experience but also the acceptance standards of the co-loader and CFS actually being used.

When the prime freight forwarder acts as an NVOCC / House B/L Issuer and undertakes transportation in relation to the shipper, the subordinate co-loader’s refusal does not automatically eliminate the responsibility to explain the situation to the shipper and arrange alternatives.

If the prime freight forwarder acts only as a Simple Intermediary and accurately relays the co-loader’s response, the scope of responsibility may differ. Ultimately, the quotation, booking conditions, House B/L, and actual explanations should be confirmed.

Cargo Insurance and Freight Forwarder Liability Insurance

Cargo unsuitable for co-loading may have a higher likelihood of incidents or damage escalation than regular cargo.

Cargo insurance compensates for damage to the cargo itself according to the terms of the insurance contract. However, damage caused by inadequate packing, normal temperature variations, inherent defects, delay, or the cargo’s inherent nature may not be covered under the insurance terms.

Having cargo insurance does not obligate the CFS or carrier to accept the cargo. Acceptance criteria, packing conditions, and insurance terms must be confirmed separately.

If the prime freight forwarder provides incorrect acceptance guidance, fails to perform necessary checks, or arranges inappropriate alternative transportation, the resulting liability may fall within the scope of freight forwarder liability insurance. Actual coverage depends on the cause of the incident, contracts, exclusions, and insurance terms.

In the event of a cargo incident or damage resulting from refusal of acceptance, contact the insurance company or handling insurance agent promptly to prevent further damage and preserve rights.

Summary

“Cargo unsuitable for co-loading” refers to cargo that is generally difficult to consolidate safely and properly in the same container with other shippers’ cargo as a standard LCL shipment.

Dangerous goods, long cargo, heavy cargo, temperature-controlled cargo, odorous cargo, liquid cargo, powdered cargo, poorly packed cargo, and high-value goods may be difficult to accept as standard LCL shipments.

Whether cargo is suitable for co-loading is determined not only by its size but also by factors such as hazards, impact on other cargo, CFS handling capability, packing condition, temperature requirements, required documentation, shipping line policies, co-loader rules, and CFS acceptance standards.

If there is uncertainty about acceptance, submit the product name, material, composition, use, dimensions, unit weight, packing form, SDS, and photographs before booking. Acceptance should be confirmed with the operator that will actually arrange the consolidation and with the relevant CFS.

Even after booking is confirmed, acceptance may be suspended or refused following in-gate inspection if the declared information differs from the actual cargo or the CFS acceptance conditions are not met.

When acceptance is refused, the first step is to verify cargo safety, arrangements for the scheduled vessel, alternative plans, and the impact on the delivery schedule. Responsibility for drayage, repacking, storage, or next-vessel costs depends on the cause, declared information, prior approvals, quotation terms, and contractual status.

Cargo unsuitable for standard LCL consolidation may still be transported through dangerous goods-compatible LCL, dedicated co-loading, FCL, air transport, dedicated services, or repacking. As a basic practical rule, co-loading feasibility should be confirmed as early as possible and before the cargo arrives at the CFS.

Actual acceptance, liability, and cost allocation may vary depending on the nature of the cargo, contracts, quotation terms, transport documents, clauses, applicable laws and regulations, prior approvals, and available evidence.
