Small Quantity Hazardous Materials
Interlink編集部What Are Limited Quantities?
Limited quantities refer to substances classified as dangerous goods but that meet specific volume, weight, and packaging requirements allowing them to be handled under the limited quantities classification during transport. In English, this classification is called Limited Quantities and is often abbreviated as LQ.
In freight forwarding practice, it is important to recognize the common misconception that "small quantities mean the cargo is not dangerous goods." Limited quantities are still considered dangerous goods and must be handled according to packaging, labeling, documentation, and acceptance conditions that meet specified requirements.
In other words, limited quantities are not general cargo. They pertain to goods with hazardous properties where the capacity of inner packaging, outer packaging, total gross weight, markings, and transport mode-specific conditions are fulfilled, allowing certain simplifications in handling compared to regular dangerous goods transport.
In practice, confirming limited quantity status often arises with items such as paints, adhesives, cleaning agents, cosmetics, aerosol products, reagents, industrial chemicals, and samples. However, determination should never be based solely on product names or quantity impressions when considering if LQ classification applies.

Basic Concepts of Limited Quantity Dangerous Goods
Limited quantity dangerous goods apply when hazardous materials are packed in small inner containers and further packaged in outer containers that meet regulatory requirements. This is relevant for items such as paints, adhesives, cleaning agents, cosmetics, aerosol products, reagents, and industrial chemicals.
However, not all hazardous goods can be transported as limited quantity dangerous goods. Whether a shipment qualifies depends on factors such as the UN number, proper shipping name, hazard class, packing group, capacity of inner containers, conditions of outer packaging, and transport mode.
Even if the shipper states that “the containers are small,” “these are samples,” or “there is only a small amount,” this alone does not guarantee transport as limited quantity dangerous goods. It is necessary to review the SDS, dangerous goods classification, UN number, packing details, quantity, and mode of transport to confirm whether the shipment meets the criteria for limited quantity handling.
Differences Between Limited Quantity Dangerous Goods and General Cargo
Limited quantity dangerous goods do not have the same meaning as general cargo. They refer to cargo that is classified as dangerous goods but may be transported under simplified conditions if certain criteria are met.
| Category | Meaning | Practical Considerations | Actions When Issues Arise |
|---|---|---|---|
| General Cargo | Cargo that does not fall under the classification of dangerous goods for transport purposes. | There may be cases where confirmation that the cargo is non-dangerous is done via the SDS or a Non-Dangerous Goods Certificate. | If markings on the goods or the SDS contain dangerous goods information, proceed with re-verification instead of treating as general cargo. |
| Limited Quantity Dangerous Goods | Cargo that qualifies as dangerous goods but meets specific volume, weight, and packaging conditions. | Confirmation is required for limited quantity markings, packaging conditions, acceptance criteria, and transport mode requirements. | If conditions for limited quantity are not met, consider arrangements as regular dangerous goods or under other applicable systems. |
| Regular Dangerous Goods | Cargo that does not meet limited quantity criteria or is declared as regular dangerous goods. | A hazardous materials declaration, proper labels, and approval from shipping lines or airlines as well as verification with dangerous goods warehouses are required. | Ensure the Dangerous Goods Declaration (DGD), labeling, packaging, and carrier and CFS conditions are all compliant. |
| Cargo Claimed as Non-Dangerous | Cargo for which the shipper states it is not dangerous goods. | Descriptions such as "limited quantity," "sample," or "small shipment" alone do not justify classification as non-dangerous. | Confirm by reviewing the SDS, Non-Dangerous Goods Certificate, manufacturer documents, and actual cargo markings. |
Even if the shipper states, "It is a limited quantity so it can be shipped as general cargo," the freight forwarder should not accept this without verification. Confirmation of the SDS, dangerous goods assessment, UN number, packaging details, and quantity is necessary. Skipping this verification may result in rejection during CFS in-gate procedures or carrier acceptance checks by airlines or shipping lines.
Differences Between Limited Quantities and Excepted Quantities
Limited Quantities and Excepted Quantities are both schemes that may allow simplified handling for certain types of dangerous goods, but they are not the same. Limited Quantities are referred to as LQ, while Excepted Quantities are called EQ. They differ in applicable conditions, quantity limits, markings, documentation, and treatment in air transport.
| Category | English Term | Basic Concept | Practical Notes |
|---|---|---|---|
| Limited Quantities | Limited Quantities | This system applies to dangerous goods that meet specific inner packaging capacity and outer packaging requirements, allowing them to be handled as LQ. | Confirm limited quantity markings, packaging requirements, and acceptance conditions for each transport mode. |
| Excepted Quantities | Excepted Quantities | This system covers even smaller quantities of dangerous goods, handled under more restrictive conditions. | Check separate quantity limits, marking, and documentation conditions specific to Excepted Quantities. |
| Common Point of Confusion | LQ and EQ | Both appear as "small amounts of dangerous goods," causing frequent confusion. | Since systems, quantity limits, markings, and acceptance conditions differ, they should not be treated as synonyms. |
| Relationship with Regular Dangerous Goods | Regular Dangerous Goods Transport | When conditions for LQ or EQ are not met, goods must be arranged as regular dangerous goods. | Confirm dangerous goods declaration, standard labels, packaging, and acceptance by the carrier. |
In practice, it is important not to rely solely on words like "small quantity," "trace amount," "sample," or "just a little." Confirm whether the cargo should be handled as LQ, EQ, regular dangerous goods, or possibly non-hazardous, based on the SDS and applicable regulations.
Cases Where Limited Quantity Rules Do Not Apply
The limited quantity provisions do not apply to all dangerous goods. Depending on the hazard class, UN number, proper shipping name, packing group, and special provisions, some goods cannot be treated as limited quantities.
| Verification Item | Reason for Verification | Practical Notes | Reference Documents / Contacts |
|---|---|---|---|
| Hazard Class | Application of limited quantity rules may be restricted by hazard class. | Particular caution is required for explosives, radioactive materials, and highly toxic substances. | SDS, hazard class references, dangerous goods specialists |
| UN Number | Allowed quantities and conditions for limited quantity treatment vary by UN number. | Even within the same hazard class, applicability may differ depending on the UN number. | SDS Section 14, dangerous goods classification materials, IMDG Code, IATA Dangerous Goods Regulations |
| Packing Group | If the hazard level is high, limited quantity rules may not apply. | Special attention is needed for high hazard cargo such as PG I. | SDS, Dangerous Goods Declaration (DGD), manufacturer confirmation documents |
| Inner Container Capacity / Weight | Limited quantity rules relate to capacity and weight limits per inner container. | Even if the overall outer packaging is small, if individual inner containers exceed limits, the rules do not apply. | Packing list, product capacity data, shipper, packing company |
| Outer Packaging / Combination Packaging | Conditions depend not only on inner containers but also on outer packaging and packing configuration. | If the outer packaging does not meet regulatory requirements, limited quantity treatment may be disallowed. | Packing photos, packaging specifications, packing company, dangerous goods specialists |
| Transport Mode | Application conditions differ between maritime and air transport. | Goods accepted as limited quantities by sea may not be accepted as such by air carriers. | Shipping lines, airlines, CFS, air cargo terminals, courier companies |
Whether cargo qualifies as limited quantity should be determined by regulatory conditions, not by the product name or packaging appearance. In particular, for air transport, although regulations may permit limited quantity, operational restrictions imposed by airlines or courier companies often result in refusal of acceptance.
Meaning of the Limited Quantity Mark
For limited quantity dangerous goods, a specific limited quantity (LQ) mark may be required, which differs from the standard hazardous materials label. This mark indicates that the cargo is classified as dangerous goods but has been packed and labeled under certain conditions as limited quantity.
The limited quantity mark does not mean the cargo is "not hazardous." Even if the standard hazardous materials label is unnecessary or simplified, it is essential that the cargo meets the labeling, packaging requirements, and acceptance criteria for limited quantity dangerous goods.
| Check Item | Purpose of Confirmation | Practical Considerations | Action if Issues Are Found |
|---|---|---|---|
| Presence of Limited Quantity Mark | Confirm whether LQ marking is required on the outer packaging. | If the mark is missing, gate-in acceptance may be halted at CFS, warehouse, airlines, or shipping lines. | Confirm the required marking before in-gate and correct the outer packaging label accordingly. |
| Relationship with Standard Hazard Labels | Verify whether the cargo qualifies for LQ marking instead of the regular hazardous materials label. | Do not confuse whether cargo should be treated as standard hazardous or limited quantity. | Check SDS, UN number, quantity, and packaging conditions. |
| Marking on Outer Packaging | Confirm the LQ cargo can be identified on the outer packaging unit. | Check markings not only on inner containers but also on outer packaging. | Review packaging photographs, packing lists, and CFS/air cargo terminal conditions. |
| Marking for Air Transport | Additional markings or air transport-specific conditions may be required. | Marine markings alone may not be sufficient for air transport. | Confirm IATA regulations, differences among airlines, and any airline-designated markings. |
| Consistency Between Mark and Actual Cargo | Verify that the LQ mark matches the actual quantity and packaging conditions. | Applying the mark alone does not permit LQ treatment if conditions do not match. | Cross-check packing list, quantities, inner container capacities, and outer packaging. |
The size, shape, placement of the mark, and any additional air transport requirements should be confirmed against the latest regulations and carrier acceptance criteria of shipping lines and airlines. Freight forwarders should obtain photos and packing details from the shipper to ensure the outer markings are appropriate for limited quantity dangerous goods.
Differences Between Maritime and Air Transport
Handling conditions for limited quantity dangerous goods differ between maritime and air transport. Maritime transport follows the IMDG Code, while air transport is governed by the IATA Dangerous Goods Regulations.
| Category | Maritime Transport | Air Transport | Practical Considerations |
|---|---|---|---|
| Main Regulations | Compliance is based primarily on the IMDG Code. | Compliance is based primarily on the IATA Dangerous Goods Regulations. | Even for the same limited quantity cargo, conditions may differ between maritime and air transport. |
| Main Verification Items | Check UN number, hazard class, packing group, inner container capacity, outer packaging, LQ marking, and CFS acceptance criteria. | Check UN number, hazard class, packing group, packaging requirements, quantity limits, LQ marking, passenger/cargo aircraft conditions, and airline-specific variations. | Quantity limits and airline-specific differences are particularly important issues in air transport. |
| Acceptance Confirmation | Confirm with shipping lines, NVOCCs, CFS, hazardous materials warehouses, and consolidation agents. | Confirm with airlines, air freight forwarders, courier companies, and airport cargo facilities. | Even if permitted by regulations, acceptance may be denied per each company’s internal rules. |
| Operational Notes | In LCL consolidations, CFS or consolidators may refuse limited quantity dangerous goods. | Even small quantities may be rejected due to airline-specific restrictions or courier prohibitions. | For urgent shipments, transportation mode and acceptance conditions should be finalized as early as possible. |
| Documentation and Marking | Verify dangerous goods details, LQ markings, in-gate conditions, and consolidation eligibility. | Verify air waybills, LQ markings, and airline-mandated conditions on air transport documents. | Information prepared for maritime transport should not be directly applied to air transport without appropriate adjustment. |
Cargo accepted as limited quantity dangerous goods under maritime transport may be refused in air transport due to packaging standards, quantity limits, or airline-specific restrictions. For urgent or sample shipments, transportation mode should be confirmed early, and limited quantity conditions verified promptly.
Relationship with SDS and Hazardous Goods Assessment Documents
To determine whether cargo qualifies as limited quantity hazardous goods, start by reviewing the SDS and hazardous goods assessment documents. The transport information section of the SDS may include details such as the UN number, proper shipping name, hazard class, packing group, and the presence of marine pollutants.
However, the SDS alone may not provide sufficient information to determine packaging requirements or acceptance eligibility as limited quantity hazardous goods. While the SDS includes hazardous material classification, it often does not specify the capacity of inner containers, outer packaging, LQ markings, or mode-specific transport conditions.
Therefore, freight forwarders should use the SDS as a primary reference but also confirm details with the shipper, manufacturer, hazardous materials specialists, shipping lines, airlines, and CFS. Particularly if the SDS contains hazardous goods information but the shipper states the cargo is ordinary due to small quantities, verifying the supporting documentation is essential.
Comparison Table of Freight Forwarder Involvement
| Category | Supportable Actions | Actions to Avoid Conclusive Judgments On | Practical Handling |
|---|---|---|---|
| Initial Verification of Small Quantity Dangerous Goods | Verifying the SDS, UN number, official shipping name, hazard class, and packing group. | Judging LQ status based solely on descriptions such as "small quantity" or "sample." | Obtain the latest SDS and packing details. |
| Confirming Eligibility for LQ Application | Checking the capacity of inner containers, outer packaging, total weight, markings, and transport mode conditions. | Assuming automatic LQ status because the overall packaging size is small. | Confirm LQ conditions applicable to each UN number. |
| Differentiating Between LQ and EQ | Distinguishing whether the cargo qualifies as Limited Quantities or Excepted Quantities. | Treating LQ and EQ as the same regulatory category. | Verify quantities, markings, documentation, and acceptance conditions separately. |
| Marking and Label Checks | Confirming LQ markings, outer packaging labels, and additional requirements for air transport. | Assuming all parties will accept the cargo simply because it bears an LQ mark. | Check photos of packaging, packing condition, and carrier or airline conditions. |
| Maritime Transport Confirmation | Verifying acceptance conditions with shipping lines, NVOCCs, CFS, hazardous materials warehouses, and groupage operators. | Assuming that if cargo is LQ-regulated, CFS and groupage operators will always accept it. | Confirm CFS in-gate conditions, LCL consolidation eligibility, and shipping line approval. |
| Air Transport Confirmation | Checking IATA regulations, differences between airlines, courier restrictions, and air cargo terminal conditions. | Assuming that LQ cargo allowed in maritime transport can be shipped under the same conditions by air. | Conduct prior confirmation with airlines and courier companies. |
| Document and Packing Reconciliation | Verifying consistency between SDS, dangerous goods classification statement, packing list, packing specifics, and outer packaging labels. | Assuming that confirming the SDS alone means packing conditions for LQ are fully checked. | Cross-check photos of packaging, inner container capacities, outer packaging, and markings. |
| Cases with Remaining Doubts | Do not proceed as regular cargo; confirm details with shipper, manufacturer, or dangerous goods specialists. | Prioritizing deadlines and proceeding with in-gate or air arrangements despite unresolved uncertainties. | Obtain supporting documentation and determine whether the cargo is LQ, EQ, regular dangerous goods, or non-dangerous. |
Common Practical Issues
Limited quantity dangerous goods often cause issues with samples and small-lot shipments. Cargo owners tend to assume "a little is no problem," but in hazardous materials transport, it is essential to verify not only the quantity but also the item, concentration, container, packing, mode of transport, and acceptance conditions.
| Case | Issue | Documents / Party to Check | Recommended Action |
|---|---|---|---|
| The shipper explains it is "ordinary cargo because it is a small quantity" | Confusion between limited quantity hazardous goods and general cargo. | SDS, UN number, packing details, shipper/manufacturer | Determine if it qualifies as Limited Quantities (LQ), Excepted Quantities (EQ), regular dangerous goods, or non-hazardous cargo. |
| Confusing LQ with EQ | Assuming limited quantity and excepted quantity dangerous goods are governed by the same rules. | SDS, hazardous materials classification letter, quantity details, regulatory conditions | Confirm whether it is Limited Quantities or Excepted Quantities and separately verify marking, quantity, and documentation requirements. |
| Inner container capacity exceeds limits | Reviewing only total quantity of outer packaging without checking inner container size limits. | Packing list, inner container capacity, outer packaging, P/L | Confirm capacity and weight limits for each inner container as well as conditions for the overall outer packaging. |
| Missing limited quantity markings | Insufficient verification of marking requirements or mistaken classification as ordinary cargo. | Photos of outer packaging, packing specifications, carrier conditions | Verify required markings, placement, and outer packaging labels, and ensure correction before in-gate. |
| CFS or consolidation agent refuses acceptance | Even limited quantity cargo may be restricted due to internal rules or storage conditions. | Shipping line, NVOCC, CFS, hazardous materials warehouse, consolidation agent | Confirm acceptance conditions in advance and consider alternative CFS, FCL shipment, or hazardous materials warehouse. |
| Rejected by airline or courier | Insufficient confirmation of airline-specific restrictions, quantity limits, or packaging standards. | IATA conditions, airline responses, courier responses, packing documents | Reconfirm air transport requirements and consider ocean transport, different airline, or alternative routing. |
| SDS indicates hazardous but invoice only says "sample" | Hazardous nature not communicated through product name or usage. | SDS, hazardous materials classification letter, invoice, P/L, shipper confirmation | Clarify proper shipping name, UN number, and transport conditions, and harmonize documentation accordingly. |
| Using limited quantity status applied in maritime transport for air transport | Confusing limited quantity conditions, packaging, and quantity limits between maritime and air transport. | IATA regulations, airline responses, SDS, packing details | Reconfirm under air transport conditions and consider different transport mode if acceptance is denied. |
4-Column Verification Checklist
| Verification Scenario | Party to Confirm With | Items to Confirm | Action If Issues Are Found |
|---|---|---|---|
| When the shipper describes cargo as "small quantity" or "sample" | Shipper / Manufacturer | Verify the SDS, UN number, proper shipping name, hazard class, and packing group. | Do not treat as non-hazardous cargo based on description alone; confirm hazardous classification. |
| When requested to arrange transport as Limited Quantity (LQ) | Shipper / Dangerous Goods Specialist | Check whether LQ applies by UN number, interior container capacity, outer packaging, and total weight. | If conditions do not match, consider arranging as regular dangerous goods or under a different scheme. |
| When the distinction between Limited Quantities and Excepted Quantities needs to be made | Shipper / Manufacturer / Dangerous Goods Specialist | Confirm whether cargo qualifies as Limited Quantities or Excepted Quantities, including quantity, labeling, and documentation conditions. | Avoid confusing the two schemes; re-verify under the applicable scheme’s conditions. |
| When checking outer packaging markings | Shipper / Warehouse / CFS / Air cargo terminal | Verify LQ mark, placement, outer package condition, and relationship to standard labels. | Correct any marking deficiencies prior to in-gate. |
| When arranging maritime transport | Shipping Lines / NVOCC / CFS / Consolidators | Confirm IMDG Code LQ conditions, CFS in-gate acceptance, eligibility for LCL consolidation, and shipping line conditions. | If not accepted, consider alternative CFS, full container load (FCL), dangerous goods warehouse, or different shipment method. |
| When arranging air transport | Airline / Air Freight Forwarder / Courier Company | Verify IATA conditions, quantity restrictions, packaging standards, airline variations, and courier limitations. | If rejected, consider sea transport, alternative airline, or different routing. |
| When verifying packing details | Shipper / Packaging Supplier / Warehouse | Confirm the capacity and weight of each inner container, outer packaging, combination packaging, and total weight. | If conditions exceed limits, repackage or switch to regular dangerous goods handling. |
| When cargo appears likely to be accepted as non-hazardous | Shipper / Warehouse / CFS / Air cargo terminal | Cross-check SDS, actual markings, outer packaging labels, invoice, and packing list consistency. | If doubts arise, withhold in-gate and loading until classification basis is confirmed. |
Example 1: Case Where Samples Were Requested to Be Shipped as Non-Hazardous Cargo
A shipper requested to send a small quantity of cleaning agents by air, stating that since they were samples, they could be treated as general cargo.
However, upon reviewing the SDS, the UN number and hazard class were listed, indicating the cargo qualifies as dangerous goods for transport purposes. The fact that the cargo is a sample or small quantity does not mean it is non-hazardous.
The freight forwarder confirms the SDS, UN number, proper shipping name, hazard class, packing group, inner container capacity, and airline acceptance conditions.
If the cargo cannot be handled as Limited Quantity (LQ), the forwarder arranges it as regular dangerous goods or considers alternative transport methods, repackaging, or changing the shipment timing.
Example 2: Case of Confusing LQ and EQ Causing Incorrect Labeling
This case involves a shipper who assumed that, because the quantity was small, the cargo could be treated the same as limited quantities and mistakenly confused the labeling and documentation requirements for Limited Quantities (LQ) and Excepted Quantities (EQ).
Both Limited Quantities and Excepted Quantities relate to small volumes of hazardous materials, but they differ in terms of regulations, quantity limits, labeling, and documentation requirements.
The freight forwarder needs to review the SDS, UN number, hazard class, packing group, inner container capacity, and outer packaging conditions to determine whether the cargo should be handled as LQ or EQ.
If the labeling or packing does not comply with the applicable regulations, repacking, label correction, or document amendment should be completed before in-gate.
Example 3: Case Where the Inner Container Exceeded LQ Quantity Limits
Although the overall outer packaging quantity appeared small, the capacity of each individual inner container exceeded the LQ requirements.
For limited quantity (LQ) dangerous goods, not only the total quantity of the outer packaging but also the capacity and weight of each inner container are important. Even if the outer packaging is small, if the inner container exceeds the allowed limits, the cargo may not qualify as LQ.
Freight forwarders should verify the packing details, inner container capacities, outer packaging, total weight, and LQ conditions according to each UN number.
If the cargo does not meet the requirements, options to consider include repacking, changing the inner container, handling as regular dangerous goods, or using an alternative transport mode.
Example 4: Accepted as LQ in Maritime but Rejected for Air Transport
This case involved a product that was previously shipped as Limited Quantity (LQ) by sea, but the shipper requested to switch to air transport to shorten the delivery time.
The conditions for LQ, packaging standards, quantity limits, airline differences, and courier acceptance rules vary between maritime and air transport. Even if a shipment was accepted as LQ by sea, it does not guarantee the same treatment for air transport.
The freight forwarder confirms IATA regulations, airline responses, courier restrictions, packaging, quantity limits, LQ markings, and AWB documentation requirements.
If the airline cannot accept the cargo, the forwarder proposes alternatives to the shipper such as continuing maritime transport, using a different airline, cargo-only flights, alternative routes, or rescheduling delivery dates.
Points to Confirm with the Shipper
For cargo that may be handled as limited quantity dangerous goods, the freight forwarder should confirm the following information with the shipper early in the process.
- Whether the latest version of the SDS is available.
- Whether the UN number, proper shipping name, hazard class, and packing group have been verified.
- Whether the UN number and item are eligible to be handled as limited quantity dangerous goods.
- Whether the capacity and mass per inner packaging unit comply with the applicable limits.
- Whether the outer packaging, combination packaging, and packing condition meet the requirements.
- Whether LQ markings or outer package labels are required.
- Whether the shipment will be arranged for maritime or air transport.
- If by air, whether the airline or courier company can accept the cargo.
- Whether the CFS, consolidator, dangerous goods warehouse, and shipping line can accept the cargo.
- Whether the distinction between limited quantity, regular dangerous goods, and non-dangerous goods has been confirmed.
- Whether the invoice or packing list only states "sample" or "small quantity" without including dangerous goods information.
Common Misunderstandings
With limited quantity dangerous goods, terms like "small quantity," "sample," or "small lot" often lead to skipping proper hazardous materials confirmation. The following misunderstandings can frequently cause in-gate refusal or loading denial.
| Misunderstanding | Practical Approach | What Should Be Checked |
|---|---|---|
| Limited quantity dangerous goods are not hazardous goods | Limited quantities are a category handled under the assumption that they are hazardous goods but subject to certain conditions. | Check the SDS, UN number, hazard class, and LQ conditions. |
| Any small quantity automatically qualifies as LQ | It is necessary to verify the UN number, hazard class, packing group, inner container capacity, and outer packaging conditions. | Confirm packing details, inner container capacity, outer packaging, and regulatory requirements. |
| LQ and EQ mean the same thing | Limited Quantities and Excepted Quantities are distinct regulatory systems. | Check quantity, labeling, documentation requirements, and acceptance conditions for each system. |
| Having an LQ mark guarantees acceptance | The LQ mark alone is insufficient; packing conditions, quantity, acceptance criteria, and transport mode must be verified. | Confirm outer packaging labeling, packing, quantity, and shipping line or airline conditions. |
| If it qualifies as LQ by sea, it can also be shipped as LQ by air | For air transport, IATA requirements, airline differences, quantity limits, and packing standards must be checked separately. | Verify airline, courier, and airside warehouse conditions. |
| Samples do not require a hazardous materials declaration | Samples may still qualify as dangerous goods. | Check the SDS, dangerous goods classification letter, UN number, and official shipping name. |
| A small overall outer package can be treated as LQ | If the capacity or weight per inner container exceeds the conditions, it may not be treatable as LQ. | Check inner container capacity, outer packaging, gross weight, and packing details. |
| If the shipping line accepts it, CFS or consolidation agents will also accept it | Acceptance decisions by shipping lines, CFS, dangerous goods warehouses, and consolidation agents are separate. | Confirm CFS in-gate conditions, LCL consolidation acceptance, and dangerous goods warehouse conditions. |
Practical Considerations
- Limited quantity dangerous goods should be treated as hazardous cargo and not as general cargo.
- Do not confuse Limited Quantities with Excepted Quantities.
- Verify the UN number, proper shipping name, hazard class, and packing group.
- Check the capacity and mass of each inner packaging as well as the conditions of the outer packaging.
- Confirm whether limited quantity marks or outer package labels are required.
- Be aware that conditions may differ between maritime and air transport and check accordingly.
- Pre-confirm acceptance eligibility with CFS operators, consolidation agents, shipping lines, airlines, and couriers.
- Do not rely solely on the SDS; confirm packaging condition, quantity, markings, and transport mode together.
- Verify that the invoice or packing list does not merely state "sample" or "small quantity" without including hazardous goods information.
- If any doubts arise, confirm details with the shipper, manufacturer, or hazardous materials specialists.
Summary
Limited quantity dangerous goods refer to substances classified as dangerous goods that, when meeting specific volume, weight, and packaging requirements, may be handled under a designated limited quantity category for transport. Limited quantity cargo is not treated as general cargo but is handled on the premise that it is hazardous.
For limited quantity dangerous goods, it is necessary to verify the UN number, proper shipping name, hazard class, packing group, capacity of inner packaging, outer packaging, limited quantity markings, and the transport mode-specific conditions. This system is separate from the Excepted Quantity system, so LQ and EQ should not be treated as the same.
Freight forwarders should not proceed solely on the assumption that “small quantity means no problem.” Instead, they must promptly confirm the SDS, dangerous goods classification statements, packing details, quantities, markings, and acceptance conditions of CFS, shipping lines, and airlines to prevent in-gate refusals, shipment delays, and refusals for air carriage.
The main takeaway of this article is that limited quantity dangerous goods should not be treated as “non-hazardous small-lot cargo” but as a practical transport category based on the premise that the cargo is hazardous, requiring confirmation of LQ conditions, packaging, markings, transport mode, and acceptance capability.
