Dangerous Goods — Meanings Across Regulatory Regimes and Practical Checks
Interlink編集部What Are Hazardous Materials?
Hazardous materials refer to substances or products that pose risks such as fire, explosion, toxicity, corrosiveness, environmental pollution, heat generation, or reactivity, and therefore require careful handling, storage, and transportation.
However, the meaning of "hazardous materials" varies depending on the regulatory framework. For example, hazardous materials under the Fire Services Act, hazardous materials for maritime transport, Dangerous Goods in air transport, poisons and toxic substances under the Poisonous and Deleterious Substances Control Act, and high-pressure gases regulated by the High-Pressure Gas Safety Act each have different purposes and scopes for verification.
In international logistics practice, "hazardous materials" is an important term verified not just for general danger but specifically in connection with the UN number, proper shipping name, hazard class, packaging group, Safety Data Sheet (SDS), hazardous material declaration, labels, markings, warehouse storage, CFS in-gate, and acceptance conditions of shipping lines and airlines.
For freight forwarders, it is essential to distinguish which regulatory system the term "hazardous materials" applies to upon encountering it in practice.

Perspectives on Hazardous Materials by Regulatory Framework
The confirmation purpose for hazardous materials varies by regulatory framework. The laws and references differ depending on whether the focus is on fire prevention, safety in maritime transport, safety in air transport, or handling of toxic or high-pressure gases.
| Regulatory Framework / Rule | Main Perspective | Relevance to Freight Forwarder Operations | Notes When Verifying |
|---|---|---|---|
| Fire Services Act | Focuses on hazardous materials that pose fire prevention concerns for domestic storage and handling. | Related to hazardous materials warehouses, domestic storage, temporary storage, specified quantities, hazardous materials facilities, and acceptance conditions at delivery destinations. | Verification is separate from determining hazardous materials status for international transport. |
| IMDG Code | Ensures safe maritime transport by confirming UN numbers, hazard classes, packaging, labeling, stowage, and segregation. | Relevant for shipping line bookings, CFS in-gate, LCL consolidation, marine pollutants, and dangerous goods declarations. | Even if accepted by the shipping line, CFS or the destination side may reject the cargo. |
| IATA Dangerous Goods Regulations | Ensures safe air transport by verifying classification, packaging, quantity limits, labels, marks, and declarations. | Concerns airline acceptance, passenger aircraft carriage eligibility, cargo-only aircraft, lithium batteries, aerosols, and air dangerous goods documentation. | Acceptance in maritime transport does not guarantee acceptance in air transport. |
| Poisonous and Deleterious Substances Control Act | Manages substances with high risk of acute toxicity as poisons or deleterious substances. | Related to import, sale, transfer, storage, labeling, theft/leakage prevention, and domestic handling. | Verification of domestic regulatory control differs from hazardous materials status for transport. |
| High Pressure Gas Safety Act | Ensures safety related to manufacturing, storage, sale, transportation, and consumption of high-pressure gases. | Applies to gas cylinders, refrigerants, liquefied gases, compressed gases, aerosol-related cargo, and domestic transport/storage. | Verification of gas type, pressure, container, carrier conditions, and delivery acceptance is required. |
| Chemical Regulations and Occupational Health & Safety | Confirms chemical hazards, labeling, SDS, worker protection, and risk management. | Related to SDS, GHS labeling, domestic handling by importers and shippers, and product safety management. | Verification should cover not only transport eligibility but also who and how the cargo is handled domestically. |
The same cargo may require confirmation under multiple frameworks, such as hazardous materials under the Fire Services Act, dangerous goods for maritime transport, Dangerous Goods for air transport, or deleterious substances under the Poisonous and Deleterious Substances Control Act.
For issues concerning SDS, GHS labeling, and chemical hazard communication under chemical regulations and occupational health and safety, please refer to the SDS and GHS Labeling articles for detailed verification guidance.
Documents to Verify by Regulation
The documents required to confirm whether cargo qualifies as hazardous materials vary depending on the specific regulatory framework being checked.
| Verification Subject | Main Documents | Notes | Parties to Confirm With |
|---|---|---|---|
| Hazardous materials under the Fire Services Act | SDS, ingredient list, flash point data, Fire Services Act applicability documents, hazardous materials classification documents | Checked separately from transport classification when dealing with domestic storage or warehouse acceptance | Shipper, manufacturer, warehouse operator, specialized experts |
| Hazardous materials for maritime transport | SDS Section 14, UN number, proper shipping name, hazard class, hazardous materials declaration | Classification, packaging, labeling, stowage, and segregation under the IMDG Code are key considerations | Shipper, manufacturer, shipping line, CFS |
| Hazardous materials for air transport | SDS Section 14, UN number, IATA Dangerous Goods information, air hazardous materials declaration, airline confirmation | Acceptance for sea transport does not guarantee acceptance for air transport | Shipper, manufacturer, airline, courier company |
| Whether classified as toxic or hazardous substances | SDS, ingredient list, documents applicable to the Poisonous and Deleterious Substances Control Act, manufacturer confirmation | Management requirements include import, sales, storage, and transfer control as well as transport eligibility | Shipper, importer, manufacturer, customs broker, specialized experts |
| Whether classified as high-pressure gas | SDS, product specifications, container information, gas type, pressure data, manufacturer confirmation | Transport, storage, inland delivery, and consignee acceptance conditions should be verified separately | Shipper, manufacturer, delivery company, consignee |
| Whether it can be considered non-hazardous | Non-hazardous certificate, SDS, product specifications, manufacturer confirmation documents | Do not rely solely on a non-hazardous certificate; confirm there are no contradictions with the SDS or actual packaging labels | Shipper, manufacturer, hazardous materials specialists |
Cases Where Judgments Differ Between Regulatory Systems
The most critical issue in hazardous materials handling is that different regulations may have conflicting classifications and requirements.
For example, substances not classified as hazardous under the Fire Services Act may still qualify as dangerous goods for maritime transport. Conversely, cargo that appears non-hazardous for transport might require confirmation under the Fire Services Act when stored domestically.
| Scenario | Common Situations | Freight Forwarder’s Practical Response | Documents and Parties to Confirm |
|---|---|---|---|
| Classified as hazardous both under Fire Services Act and transport regulations | Flammable liquids, paints, solvents, adhesives, etc., requiring verification for both domestic storage and international transport. | Verify SDS, Fire Services Act applicability, UN number, hazard class, and acceptance conditions of warehouses, shipping lines, and CFS. | SDS, Fire Services Act documentation, Dangerous Goods Declaration, warehouses, shipping lines, CFS |
| Hazardous under Fire Services Act but transport classification depends on conditions | Domestic issues relate to flammability and specified quantities, but transport classification may vary based on quantity, packaging, concentration, or form. | Separate checks for domestic storage and transport arrangements; confirm acceptance with both warehouses and shipping/airlines. | SDS, ingredient list, storage quantity, warehouses, shipping lines, airlines |
| Not hazardous under Fire Services Act but classified as dangerous goods for transport | Lithium batteries, aerosols, marine pollutants, where transport regulations primarily determine the hazardous status. | Do not treat as regular cargo solely based on Fire Services Act non-applicability; confirm against IMDG Code, IATA Dangerous Goods Regulations, and UN numbers. | SDS, UN number, Dangerous Goods Declaration, shipping lines, airlines, CFS |
| Non-dangerous for transport but requires confirmation for domestic storage | Cargo treated as non-hazardous or simplified in transport, but domestic storage requires checks based on quantity, ingredients, flash point, or local ordinance enforcement. | Check SDS, storage quantity, applicability to Fire Services Act, relationship with specified quantities, and warehouse acceptance conditions. | SDS, Fire Services Act documentation, warehouses, cargo owner, manufacturer |
| Confirmation required under Poisonous and Deleterious Substances Control Act or High Pressure Gas Safety Act | Situations where domestic regulations for toxicity or pressurized gases apply, separate from transport or Fire Services Act classification. | Confirm with importer, cargo owner, manufacturer, and specialists to clarify domestic handling, delivery, and storage conditions. | Importer, customs broker, manufacturer, delivery company, specialists |
Due to differences between regulatory systems, do not rely solely on one piece of information such as “Not hazardous under Fire Services Act” or “Non-hazardous per SDS” to determine that there are no issues in international transport.
Relationship with Hazardous Materials under the Fire Services Act
Hazardous materials regulated under the Fire Services Act relate to the storage and handling of such materials domestically from a fire prevention perspective.
The Act addresses classifications, product names, properties, specified quantities, storage and handling facilities, hazardous materials handlers, and permits or notifications.
This regulation primarily concerns domestic storage and handling and should be confirmed separately from hazardous materials classification for international transport.
| Verification Item | Practical Meaning | When to Confirm | Actions if Issues Arise |
|---|---|---|---|
| Classification / Product Name | Confirm which hazardous material category applies under the Fire Services Act. | Verify at hazardous materials warehouses, domestic storage, and consignee storage locations. | Obtain SDS, Fire Services Act applicability documents, and manufacturer confirmation materials. |
| Specified Quantity | The management level for storage and handling changes depending on quantity. | Confirm before temporary storage, warehouse receipt, and before and after domestic delivery storage. | Check storage quantity, packaging, pack unit, and warehouse conditions. |
| Hazardous Materials Facilities | Facility requirements become an issue when storage or handling exceeds certain quantities. | Confirm at hazardous materials warehouses, shipper warehouses, and consignee locations. | Verify warehouses and facilities that can accept hazardous materials. |
| Hazardous Materials Handlers | Certified personnel may be required for handling operations or facility management. | Check during domestic storage, cargo handling, and consignee management. | Confirm the management system of warehouse operators and consignee sites. |
| Jurisdictional Fire Departments and Ordinance Enforcement | Verification methods and enforcement may vary by region and facility. | Confirm during warehouse selection, storage eligibility checks, and consignee confirmation. | Consult warehouse operators or the relevant fire department as needed. |
For detailed classifications and specified quantities under the Fire Services Act, refer to the article on Fire Services Act Hazardous Materials.
Relationship with Dangerous Goods in International Transport
In maritime and air transport, hazardous materials are handled as Dangerous Goods, where issues such as UN numbers, proper shipping names, hazard classes, packaging groups, dangerous goods declarations, labels, markings, segregation, and stowage conditions become critical.
For maritime transport, the IMDG Code is the primary reference, while air transport relies mainly on the IATA Dangerous Goods Regulations.
| Verification Item | Maritime Transport | Air Transport | Practical Notes for Freight Forwarders |
|---|---|---|---|
| Governing Regulations | Check the IMDG Code. | Check the IATA Dangerous Goods Regulations. | The criteria may differ between maritime and air transport. |
| Main Information to Verify | Verify the UN number, proper shipping name, hazard class, packaging group, marine pollutants, stowage, and segregation requirements. | Verify the UN number, proper shipping name, hazard class, packaging standards, quantity limits, passenger aircraft carriage allowance, and cargo aircraft only conditions. | Acceptance can vary even with the same SDS between maritime and air transport. |
| Key Stakeholders | Shipping lines, NVOCCs, CFS, hazardous materials warehouses, and customs brokers. | Airlines, consolidators, airport warehouses, and courier companies. | Verification should include not only shipping lines or airlines but also CFS, warehouses, and cargo handling facilities. |
| Common Points Where Shipments Can Be Held | Hazardous goods booking, CFS in-gate, LCL consolidation, transshipment ports, and destination CFS. | Airline acceptance checks, packaging and quantity restrictions, labeling, dangerous goods declaration, and airport warehouse in-gate. | Verification should cover storage, in-gate, and inland delivery before and after transport. |
| Points of Caution | Even if accepted by the shipping line, CFS or destination sides may reject the cargo. | Cargo accepted for maritime transport may not be accepted for air transport. | Hazardous goods confirmation must be redone when changing modes of transport. |
For classification and declaration practices in international transport, refer separately to the IMDG Code, IATA Dangerous Goods Regulations, UN numbers, hazard classes, dangerous goods declarations, and articles on hazardous materials transport.
Relation to Poisonous and Deleterious Substances
The Poisonous and Deleterious Substances Control Act regulates substances mainly due to their high risk of acute toxicity causing health hazards, classifying them as poisonous or deleterious substances.
If a substance falls under poisonous or deleterious substances, separate from hazardous materials designation for transport, domestic management issues may arise concerning manufacturing, import, sale, transfer, storage, labeling, theft and leakage prevention, transportation, and disposal.
In freight forwarder operations, for chemicals that may be classified as poisonous or deleterious, it is necessary to coordinate with importers, shippers, manufacturers, customs brokers, warehouses, and delivery companies to confirm who in the domestic supply chain is authorized, registered, and responsible for managing these substances under relevant qualifications and control systems.
Relationship with High-Pressure Gas
Cargo classified as high-pressure gas may require confirmation under the High-Pressure Gas Safety Act.
Items such as gas cylinders, compressed gases, liquefied gases, refrigerants, liquefied oxygen, liquefied ammonia, liquefied petroleum gas, and liquefied chlorine may need to be verified at various stages including transport, storage, sale, consumption, and inland delivery.
In freight forwarder operations, in addition to hazardous materials classification for maritime and air transport, it is essential to confirm storage locations within Japan, delivery companies, reception capabilities at consignee sites, container details, gas types, and pressure conditions.
Points for Freight Forwarders and Customs Brokers to Confirm
Freight forwarders and customs brokers should not determine hazardous material status based solely on the product name provided by the shipper.
Particularly, chemicals, paints, adhesives, inks, sprays, lithium batteries, cleaning agents, fragrances, alcoholic products, reagents, resin raw materials, and gas-containing products may potentially qualify as hazardous materials.
| What to Confirm | Reason | Source for Confirmation / Reference Materials | Action if Issues Are Found |
|---|---|---|---|
| Do not judge based only on the product name | The product name may not correspond to the actual hazard. | SDS, product specification sheets, manufacturer confirmation | Request additional documentation from the shipper and hold shipment as general cargo pending verification. |
| Obtain the SDS | It serves as the primary source to check hazards, transport information, and storage conditions. | Shipper, manufacturer, importer | Request the latest SDS or documentation relevant to the specific product. |
| Verify the UN number and hazard class | Essential to confirm hazardous material status for international transport. | SDS Section 14, hazardous material classification certificates, Dangerous Goods Declaration (DGD) | Confirm acceptance criteria with shipping lines, airlines, and CFS. |
| Check applicability under the Fire Services Act | This affects domestic storage and warehouse acceptance. | SDS, Fire Services Act classification documents, hazardous material classification certificates | Confirm acceptance with hazardous materials warehouses, dedicated storage facilities, and consignee’s storage conditions. |
| Check other legal regulations | There may be relevant laws such as the Poisonous and Deleterious Substances Control Act, High Pressure Gas Safety Act, Chemical Substances Control Law, Industrial Safety and Health Act, and import country regulations. | Shipper, customs broker, specialist vendors, related government authorities | Verify necessary permits, registrations, and management systems on the importer or shipper side. |
| Confirm acceptance availability | Even if regulations permit transport, shipping lines, airlines, warehouses, and CFS may refuse acceptance. | Shipping lines, airlines, CFS, warehouse operators, delivery companies | Consider alternative carriers, different CFS, hazardous materials warehouses, or other transport modes. |
Comparison Table of Freight Forwarders’ Involvement Scope
| Situation | What Freight Forwarders Can Assist With | What Should Not Be Concluded | Practical Response |
|---|---|---|---|
| When the term "hazardous materials" is mentioned | Confirm which regulatory framework’s hazardous materials definition is being addressed. | Determining transport or storage eligibility based solely on the term "hazardous materials." | Differentiating among the Fire Services Act, IMDG Code, IATA Dangerous Goods Regulations, Poisonous and Deleterious Substances Control Act, and High Pressure Gas Safety Act. |

| Judged the cargo was non-hazardous because it was a small sample quantity | Confusing low quantity with absence of hazardous classification. | SDS, volume, composition, transport details, storage conditions | Confirm requirements for small quantity hazardous materials, limited quantities, specified quantities, and acceptance conditions. |
4-Column Verification Checklist
| Verification Scenario | Party to Confirm With | Items to Verify | Actions if Issues Arise |
|---|---|---|---|
| When the shipper states the cargo is "not hazardous" | Shipper / Manufacturer | Confirm under which regulatory framework it is not classified as hazardous, review SDS, non-hazardous certificate, and physical markings. | Recheck separately against Fire Services Act, IMDG Code, IATA Dangerous Goods Regulations, Poisonous and Deleterious Substances Control Act, and High Pressure Gas Safety Act. |
| When handling chemicals, liquids, sprays, or products containing batteries | Shipper / Manufacturer | Verify SDS, GHS markings, UN number, hazard class, and applicability under Fire Services Act. | Do not rely solely on product name; request additional documentation as needed. |
| When domestic storage is required | Warehouse operator / Shipper / Manufacturer | Confirm Fire Services Act applicability, specified quantities, stored amounts, and warehouse acceptance criteria. | If general warehouses are unsuitable, consider hazardous materials warehouses or dangerous goods warehouses. |
| When arranging maritime shipping | Shipping line / NVOCC / CFS | Verify hazardous materials classification under IMDG Code, UN numbers, Dangerous Goods Declaration (DGD), CFS in-gate conditions, and compatibility for consolidation. | If acceptance is refused, consider alternative shipping lines, different CFS, FCL shipment, or separate voyages. |
| When arranging air transport | Airline / Courier company / Air freight agent | Check hazardous materials classification under IATA Dangerous Goods Regulations, quantity limits, packaging, and passenger aircraft carriage permissions. | If acceptance is refused, consider cargo aircraft service, different airlines, or maritime transport. |
| If there is a possibility of poisonous or deleterious substances | Shipper / Importer / Manufacturer / Customs broker | Confirm applicability under Poisonous and Deleterious Substances Control Act, and regulations for import, sale, storage, transfer management, and labeling. | If domestic handling procedures are unclear, consult importers or specialized contractors. |
| If there is a possibility of high-pressure gas | Shipper / Manufacturer / Delivery company / Consignee | Confirm gas type, pressure, container details, storage, domestic delivery, and consignee acceptance conditions. | If standard delivery is unavailable, identify delivery companies or storage facilities that can accommodate the cargo. |
| If regulations may apply in the importing country | Local agent / Importer / Customs broker | Check the importing country’s chemical regulations, hazardous materials regulations, and warehouse and delivery conditions. | If there is a risk of cargo detention locally, finalize acceptance conditions before shipment. |
Example 1: Cargo Not Subject to Fire Service Act but Classified as Dangerous Goods for Maritime Transport
This concerns a case where the shipper explained that the cargo was not classified as hazardous under the Fire Service Act and could therefore be shipped as general cargo.
However, upon reviewing Section 14 of the SDS, a UN number and hazard class were indicated, making the cargo classified as Dangerous Goods under the IMDG Code and requiring verification by the shipping line.
In this situation, relying solely on the information that the cargo is not subject to the Fire Service Act to conclude that it is not hazardous for maritime transport is incorrect. The Fire Service Act addresses domestic storage and handling, while the IMDG Code focuses on maritime transport safety, so their verification purposes differ.
The freight forwarder should check the SDS, Dangerous Goods Declaration (DGD), UN number, proper shipping name, and hazard class, and confirm acceptance acceptance with the shipping line, CFS, and consolidators.
Example 2: Cargo Classified as Non-Hazardous for Transport but Rejected for Warehouse Storage
This case involves cargo that the shipper explained as "non-hazardous for transport" and provided a non-hazardous certificate for, but required temporary storage for several days before export.
Even if cargo is considered non-hazardous for transport, domestic storage may raise issues related to applicability under the Fire Services Act, specified quantities, warehouse acceptance criteria, odor, leakage risks, and storage volume.
In this instance, the general warehouse reviewed the SDS and storage quantity and concluded the cargo could not be accepted. A non-hazardous classification for transport alone does not guarantee warehouse storage approval.
The freight forwarder should verify whether the cargo falls under the Fire Services Act, assess storage quantities, packaging, and warehouse conditions, and consider alternatives such as hazardous materials warehouses, dangerous goods warehouses, direct CFS in-gate, or adjusting the storage dates as needed.
Example 3: Attempting to Handle Chemicals Classified as Poisonous or Deleterious Substances as Regular Import Cargo
In this case, the shipper explained that the chemical sample posed no significant transportation issues. However, upon verifying its components, it was found that the substance could be classified as a poisonous or deleterious chemical.
If classified as poisonous or deleterious, beyond hazardous materials considerations for transport, domestic regulations on importation, sale, transfer, storage, labeling, and theft or leakage prevention become relevant.
The freight forwarder should review the SDS, component list, and poisonous/deleterious chemical classification documents, and confirm the domestic handling systems with the importer, customs broker, shipper, manufacturer, and specialized professionals.
It is important to confirm not only whether the cargo qualifies as hazardous materials for transport but also who will manage it after import and under what control system.
Example 4: Attempt to Deliver a Product Containing High-Pressure Gas via Regular Delivery
This case involves a shipper requesting domestic delivery of products containing gas-filled parts or refrigerants as regular cargo.
If the cargo qualifies as high-pressure gas, aside from hazardous materials classification for maritime or air transport, issues under the High-Pressure Gas Safety Act may arise regarding storage, transportation, container requirements, delivery company conditions, and acceptance criteria at the delivery destination.
The freight forwarder should review the SDS, product specifications, gas type, pressure details, and container information, then confirm acceptance with the domestic delivery company, consignee, shipper, and manufacturer.
If regular delivery cannot be accepted, alternatives such as delivery companies equipped to handle the cargo, appropriate storage facilities, delivery date adjustments, or alternative routes should be considered.
Points to Confirm with the Shipper
For cargo that may be classified as hazardous materials, freight forwarders should confirm the following information with the shipper at an early stage.
- Under which regulatory framework is this cargo being identified as hazardous?
- Is the Safety Data Sheet (SDS) the latest version?
- Does Section 14 of the SDS's transportation information include a UN number and hazard class?
- Does it fall under hazardous materials as defined by the Fire Services Act?
- Has the relationship to specified quantities been confirmed?
- Is this cargo classified as dangerous goods under the IMDG Code?
- Is it classified as dangerous goods under the IATA Dangerous Goods Regulations?
- Is confirmation required under other laws such as the Poisonous and Deleterious Substances Control Act, High Pressure Gas Safety Act, Chemical Substances Control Law, or Industrial Safety and Health Act?
- If a non-hazardous materials certificate is provided, what is the basis for this?
- Can the warehouse, CFS, shipping line, airline, and delivery company accept this cargo?
- Is there a possibility of additional regulations imposed by the importing country?
Common Misunderstandings
The most important point regarding hazardous materials is that the criteria differ across regulations. The following misunderstandings often lead to issues in freight forwarder practice.
| Misunderstanding | Practical Consideration | What Should Be Checked |
|---|---|---|
| If it is not classified as hazardous under the Fire Services Act, it is not a dangerous good in international transport | The Fire Services Act and the IMDG Code/IATA Dangerous Goods Regulations differ in purpose and classification. | Confirm applicability based on SDS Section 14, UN number, IMDG Code, and IATA Dangerous Goods Regulations. |
| If it is not a dangerous good for international transport, domestic storage is not an issue | Cargo not classified as hazardous for transport may still require checks under the Fire Services Act, local ordinances, and warehouse conditions. | Check Fire Services Act applicability, specified quantities, and warehouse acceptance conditions. |
| If the SDS states “not applicable,” everything is fine | The SDS may be outdated, have inadequate transport information, or not correspond to the actual product. | Verify the latest SDS, target product, transport information, and on-site labeling. |
| The term “hazardous materials” means the same thing across all regulations | The scope varies among the Fire Services Act, maritime transport, air transport, Poisonous and Deleterious Substances Control Act, and High Pressure Gas Safety Act. | Distinguish which regulatory framework’s definition of hazardous materials is being addressed. |
| Small quantities are not hazardous materials | Even small quantities may require confirmation of applicability and specific storage or transport conditions. | Check quantities, specified quantities, small quantity hazardous materials provisions, trace amounts, and acceptance conditions. |
| If there is a non-dangerous goods certificate, the cargo can be treated as general cargo | The non-dangerous goods certificate may conflict with the SDS, on-site markings, or regulatory applicability across systems. | Cross-check the non-dangerous goods certificate, SDS, photos of markings, and manufacturer confirmation documents. |
| If it is classified as non-hazardous in Japan, there is no issue in the importing country | Different chemical regulations, hazardous materials rules, and warehouse or delivery conditions may apply in the destination country. | Confirm with local agents, importers, and customs brokers. |
| If transport is approved, storage and delivery are also permitted | Approval for transport, storage, and delivery are separate determinations. | Individually confirm acceptance conditions with warehouses, CFS, shipping lines, airlines, and delivery companies. |
Points Freight Forwarders Should Be Aware Of
The term “hazardous materials” can have different meanings depending on the regulatory framework. Freight forwarders need to confirm which regulatory system the shipper’s explanation of “non-hazardous” is based on.
- Do not determine hazardous material status based solely on the product name.
- Do not confuse hazardous materials under the Fire Services Act with Dangerous Goods for international transport.
- Separate the confirmation of hazardous material classification for transport from that for domestic storage.
- Cross-check Safety Data Sheets (SDS), GHS markings, UN numbers, hazard classes, and Fire Services Act applicability documents.
- Confirm whether other laws such as the Poisonous and Deleterious Substances Control Act, High Pressure Gas Safety Act, Chemical Substances Control Law, Industrial Safety and Health Act, or import country regulations may apply.
- Do not rely solely on certificates of non-hazardous status; verify there are no inconsistencies with SDS or actual product markings.
- Individually confirm acceptance conditions with warehouses, CFS, shipping lines, airlines, and inland delivery companies.
- If any doubts arise, verify with the shipper, manufacturer, customs broker, hazardous materials specialists, or relevant authorities.
Summary
Hazardous materials is a general term referring to substances or products that pose risks such as fire, explosion, toxicity, corrosiveness, environmental pollution, heat generation, or chemical reactivity, requiring careful handling, storage, and transportation.
However, the exact definition of hazardous materials varies depending on the applicable regulations, such as the Fire Services Act, maritime transport rules, air transport regulations, the Poisonous and Deleterious Substances Control Act, the High Pressure Gas Safety Act, and chemical control laws.
Materials that are not classified as hazardous under the Fire Services Act may still be considered dangerous goods for maritime transport. Conversely, cargo deemed non-hazardous for transport might still require compliance with fire safety laws or warehouse conditions for domestic storage.
In freight forwarder operations, it is critical not to accept statements that cargo is "not hazardous" at face value. Instead, it should be confirmed under which regulatory framework this determination is made, while separately verifying the Safety Data Sheet (SDS), UN number, hazard class, Fire Services Act applicability, Poisonous and Deleterious Substances Control compliance, High Pressure Gas Safety Act relevance, and acceptance conditions of warehouses, CFS, shipping lines, and airlines.
This article serves as an entry point for terminology within the hazardous goods and chemical transport regulation category. Detailed transport arrangements should be verified in individual articles covering hazardous goods transport, the IMDG Code, IATA Dangerous Goods Regulations, UN numbers, hazard classes, dangerous goods declarations, hazardous materials under the Fire Services Act, hazardous materials warehouses, and related topics.
The key takeaway is to avoid treating hazardous materials simply as a general term meaning “dangerous items.” Instead, it is essential to clarify which regulatory framework the hazard classification belongs to and to verify requirements separately for transport, storage, customs clearance, warehousing, inland delivery, and destination country regulations.
