SDS

What is an SDS?

SDS stands for Safety Data Sheet. It is a document that provides information on the hazards, composition, handling, storage, emergency measures, disposal and transport information of a chemical product.

SDS was previously often called MSDS, or Material Safety Data Sheet. Today, SDS is the commonly used term in chemical safety communication.

For forwarders, NVOCCs and overseas shipping offices arranging cargo to Japan, an SDS is the starting point for checking whether a cargo may be dangerous goods and how it should be handled for transport.

Overview

An SDS is used to communicate safety information about chemical substances and mixtures between business operators. It helps manufacturers, importers, sellers, users, warehouses, transport operators and other parties understand the risks and handling conditions of the chemical product.

In Japan, certain chemical substances and products containing them may require SDS provision or labelling under laws such as the PRTR-related chemical management system, the Industrial Safety and Health Act, and the Poisonous and Deleterious Substances Control Act.

For logistics practice, an SDS should not be treated as a mere chemical document. It is a practical document for checking transport classification, package safety, carrier acceptance and documentation requirements.

How Forwarders Use SDS

Forwarders use SDS mainly to check the following points:

• Whether the cargo may be classified as dangerous goods for transport
• Whether a UN number is shown
• Whether a proper shipping name is shown
• Whether a dangerous goods class applies
• Whether a packing group applies
• Whether the product is a marine pollutant
• Whether different conditions apply for sea transport and air transport
• Whether the dangerous goods declaration is consistent with the SDS

The key point is not simply to receive an SDS, but to read it against the actual cargo, package, invoice, packing list, labels and carrier requirements.

Main SDS Items to Check

For forwarding and dangerous goods review, the following SDS items are especially important:

• Product identifier or chemical name
• Composition and ingredient information
• Hazard identification
• First-aid measures
• Fire-fighting measures
• Accidental release measures
• Handling and storage precautions
• Regulatory information
• Transport information

For transport practice, the transport information section is particularly important. In many SDS formats, this corresponds to Section 14.

Section 14 may show the UN number, proper shipping name, dangerous goods class, packing group, marine pollutant status and other information relevant to sea, air or inland transport.

Important Points in the Transport Information Section

If the transport information section says “not applicable” or “not regulated,” the forwarder should check the context before accepting that conclusion.

The SDS may be outdated, prepared mainly for domestic storage, not designed for international transport, or incomplete for sea or air transport.

The transport classification may also change depending on concentration, package size, packaging form, aerosol form, battery content, flash point, mixture composition or other product details.

Forwarders should therefore compare the SDS with the invoice, packing list, actual product label, outer package markings and cargo description before booking or delivery.

Relationship with Sea and Air Transport

For sea transport, SDS information is used to check how the cargo should be handled under the IMDG Code.

For air transport, SDS information is used to check whether the cargo can be accepted under the IATA Dangerous Goods Regulations, including packaging instructions, quantity limits, labels and whether a dangerous goods declaration is required.

A cargo that can be accepted by sea may be prohibited, restricted or conditionally accepted by air.

Particular care is needed for lithium batteries, spray cans, paints, adhesives, fragrances, alcohol-containing products, reagents, cleaning agents and chemical samples, because their transport conditions may differ depending on the transport mode.

Questions to Ask the Shipper

When the SDS is unclear or incomplete, the forwarder should ask the shipper, manufacturer or overseas supplier the following points before quotation, booking, pickup, CFS delivery or airport delivery.

• Is this the latest version of the SDS?
• Is a Japanese version available, or is there a version that can be used for transport review in Japan?
• Does the product name match the invoice and packing list?
• Is the transport information section completed?
• Are the UN number, proper shipping name, dangerous goods class and packing group clearly stated?
• If the product is not regulated as dangerous goods, is there supporting documentation?
• Are the conditions different for sea transport and air transport?
• Do the actual labels and package markings match the SDS?

If necessary, the forwarder may need to request a revised SDS, manufacturer confirmation, dangerous goods classification document, statement of non-dangerous goods, or test data.

Common Problems

• The SDS is outdated and does not reflect the current classification.
• The transport information section is blank or says “under confirmation.”
• The product name on the SDS does not match the invoice.
• The UN number on the dangerous goods declaration does not match the SDS.
• Cargo that is not acceptable by air is arranged as air freight.
• The actual product has hazard labels, but the SDS says the product is not regulated for transport.
• A change in mixture concentration makes the previous SDS unusable.

These problems often appear only after booking, CFS delivery, airport delivery or carrier review. By that stage, the shipment may already face delay, rebooking, relabelling, return or additional cost.

Practical Notes for Shipments to Japan

For cargo moving to Japan, overseas forwarders should understand that Japanese importers, customs brokers, warehouses, CFS operators, shipping lines and airlines may require conservative document checking when chemical cargo is involved.

If the SDS is not in Japanese, or if the transport information is unclear, the Japanese side may ask for additional confirmation before accepting the cargo, arranging customs clearance support, or confirming delivery and storage conditions.

Japan’s formal legal requirements and actual logistics practice may not always feel the same to overseas suppliers. Even when a product appears commercially simple, the practical handling may stop if the SDS, labels, invoice description or transport documents do not match.

Key Point

An SDS is not the final answer. It is the first document that tells the forwarder where to look next.

For shipments to Japan, the forwarder should use the SDS to connect the chemical information with the actual cargo, package, transport mode, carrier rules and Japanese-side acceptance conditions.

If the SDS, cargo description, labels or transport documents do not match, the shipment should not be treated as ready. The mismatch should be resolved before booking, pickup, CFS delivery or airport delivery.
