What Is an SDS, and Why Do People Still Say MSDS?

SDS means Safety Data Sheet. MSDS means Material Safety Data Sheet, an older term that remains common in purchasing, manufacturing and international trade. A supplier may therefore send a file named “MSDS” even though current hazard-communication systems use the shorter term “SDS.” The filename alone does not establish whether the document is current, applicable or technically correct.

The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) provides a standardized 16-section SDS format. National and regional authorities implement GHS through their own rules, so legal applicability is not identical in every market. The UNECE GHS framework is the international model; an importer or supplier must still check the rules that apply where the product is supplied and used.

An SDS is primarily a chemical hazard-communication record. It helps readers identify a product, understand relevant hazards and find information on first aid, fire response, accidental release, handling, storage, exposure controls, stability, disposal and transport. It should not be treated as a battery certification or a complete shipping approval.

Is an SDS Required to Ship Lithium Batteries?

Not as a universal transport-document requirement.

In its guidance revised for the 2026 regulations, the International Air Transport Association states that an SDS is not required when offering batteries for transport under the IATA Dangerous Goods Regulations and describes an SDS as something different from a transport document. The same guidance explains that personnel in the supply chain may still ask for one and separately identifies the requirement to make a qualifying battery's UN 38.3 test summary available. IATA also cautions that its document is guidance, not the source of regulatory compliance. See IATA's 2026 Battery Guidance Document, FAQ G.01.

This distinction matters because three different questions are often mixed together:

1. Does chemical-supply law require an SDS? The answer depends on the product, its status as a substance, mixture or article, and the jurisdiction.
2. Does a transport regulation require a particular shipping document? This depends on the battery type, configuration, rating, condition, packing, quantity, mode and route.
3. Does an operating party request an SDS? A carrier, forwarder, warehouse, customer or destination agent may ask for it as part of an internal review even when it is not the transport document required by law.

An operating request should not automatically be described as legislation. Conversely, telling a requesting party that an SDS is “not legally required” may not resolve the booking: the party may need product information in another acceptable form before deciding whether it can handle the cargo.

For example, the European Chemicals Agency explains that REACH safety-data-sheet obligations primarily concern specified substances and mixtures, while suppliers of articles can have different information duties. That EU framework should not be generalized to every destination. See ECHA's Safety Data Sheets guidance.

What Information Does a 16-Section SDS Contain?

A standard SDS is organized into 16 sections. The structure makes documents easier to compare, but it does not guarantee that every entry is correct for the battery being shipped.

The U.S. Occupational Safety and Health Administration uses this 16-section sequence. Under OSHA's Hazard Communication Standard, the headings remain part of the standardized format, but OSHA does not require or enforce the content of Sections 12–15—including Section 14 transport information—because other agencies regulate those subjects. This is a useful reminder that the existence of Section 14 does not turn an SDS into a transport approval. See OSHA Appendix D and the OSHA Hazard Communication FAQ.

How to Match the SDS to the Battery Being Shipped

The most useful SDS review is a consistency check across the actual product and the other shipment records. Use the following six steps.

1. Identify the exact product and battery model

Start with the commercial product, the installed or supplied battery and the model numbers shown on labels and specifications. A document for a cell, another battery pack or an earlier product version may not describe the cargo in front of you.

Record whether the shipment contains:

• cells or batteries shipped alone;
• cells or batteries packed with equipment;
• cells or batteries contained in equipment; or
• battery-powered vehicles or another separately classified product.

Configuration affects transport classification. A generic SDS that says only “lithium-ion battery” cannot settle that question.

2. Match the manufacturer or responsible supplier

Compare the company named in Section 1 with the manufacturer, brand owner or supplier shown on the specification, product label, invoice and UN 38.3 test summary. A trading company's document may still be useful, but unexplained differences in manufacturer identity require clarification.

Check whether the address, telephone number and emergency contact appear complete and plausible. This is a document-quality check, not independent verification that the named party produced the battery.

3. Compare chemistry and electrical ratings

Match the stated chemistry to the product specification and marking. Lithium-ion, lithium metal and other battery chemistries do not share one transport description.

For rechargeable lithium-ion batteries, compare nominal voltage, capacity in ampere-hours or milliampere-hours, and watt-hour rating. Where the watt-hour rating needs to be checked, the basic relationship is:

Wh = nominal voltage (V) × rated capacity (Ah)

Convert milliampere-hours to ampere-hours before calculating. For example, 5,000 mAh equals 5 Ah. The result is only a cross-check; use the manufacturer's rated data and resolve unexplained differences instead of silently choosing one number.

4. Check the revision, version and language

Look for the date of preparation or last revision, a version number and a description of significant changes where provided. An old date does not automatically invalidate an SDS, but a document that predates a model change, chemistry change or company change should be questioned.

The language must also be usable by the intended recipient and suitable under the applicable supply rules. Do not assume that an English document alone satisfies every destination requirement.

5. Compare Section 14 with the actual configuration

Section 14 may identify a UN number, proper shipping name, hazard class and special precautions. Compare those entries with the real configuration: battery alone, packed with equipment, contained in equipment or another article.

If the SDS provides one generic UN number for every possible configuration, treat that as a prompt for further review—not as the final answer. The planned air, sea, road or multimodal movement and any State, operator or carrier variations still need to be considered.

6. Reconcile the complete document set

Place the SDS beside the battery specification, UN 38.3 test summary, product and packing photographs, commercial invoice and packing list. Compare:

• manufacturer and model identifiers;
• chemistry and electrical ratings;
• product description and configuration;
• quantity of batteries per item and package;
• gross and net weights;
• condition of the batteries;
• packing method; and
• visible marks and labels.

A review can identify missing or conflicting inputs. It is not certification that the battery, documents or package comply with every applicable requirement.

Section 14 Transport Information: A Starting Point, Not Final Approval

Section 14 is often the first place a logistics team looks because it can contain:

• a UN number;
• a UN proper shipping name;
• the transport hazard class;
• a packing group, when applicable;
• environmental-hazard information;
• special transport precautions; and
• mode-related references.

These entries are useful only when the underlying product description is accurate and the transport information matches the current shipment.

A common problem is copied text. A preparer may reuse Section 14 from a different model or list several alternative UN numbers without explaining when each applies. Another document may describe a battery installed in equipment while the shipment actually contains spare batteries in separate packages. Those are not cosmetic inconsistencies: they can change the classification, packing instruction, marks, labels and documentation.

Section 14 also cannot account for every carrier policy or route restriction. Final preparation should be based on the actual chemistry, watt-hour rating or lithium content, configuration, condition, package, quantity, mode, origin, destination and operating parties under the current rules.

SDS vs UN 38.3 Test Summary vs Shipping Documents

These records answer different questions. Supplying one does not make the others unnecessary.

The UN 38.3 test summary is not the full laboratory test report. It is a defined summary that links the battery type to specified test and traceability information. For a detailed document check, see how to check a UN 38.3 test summary.

The transport document is shipment-specific. Depending on the mode and applicable provisions, it may need the regulated description and other declarations or handling information. The exact requirement cannot be inferred from the SDS alone.

Common SDS/MSDS Problems That Delay a Battery Review

The manufacturer or model does not match

The SDS names a cell producer, but the product contains a battery assembled by another company. Or the model on the test summary differs from the model on the battery label. The relationship must be documented rather than assumed.

Electrical data conflicts

Voltage, Ah/mAh or Wh values differ across the SDS, specification and product marking. Ask the responsible supplier to explain and correct the discrepancy. Do not revise a manufacturer's document yourself merely to make the numbers agree.

The document covers the wrong product level

An SDS may describe electrolyte ingredients or a single cell, while the cargo is a multi-cell battery pack or battery-powered product. The document may provide background information without adequately identifying the shipped article.

Section 14 is generic or incompatible

The UN number may correspond to batteries shipped alone even though the batteries are contained in equipment, or the section may list incompatible alternatives without conditions. Use the actual configuration and current transport rules to determine what needs further review.

Condition is not disclosed

Used, returned, damaged, defective, recalled, waste and prototype batteries can require different handling or may face restrictions. A standard new-product SDS does not disclose the condition of each item in a shipment.

The document is incomplete or unusable

Missing pages, unreadable scans, an absent revision date, untranslated content or broken manufacturer details can prevent a reviewer from matching the record confidently.

The SDS is treated as the only evidence

An SDS cannot substitute for the applicable UN 38.3 test summary. It also does not prove the packaging, marks, labels, declaration, invoice or packing list are correct.

Shipment records contradict one another

The invoice may describe “electronic accessories,” the packing list may omit battery quantities, and photographs may show standalone spare batteries. Resolve these conflicts before booking rather than expecting the carrier to infer the cargo.

What to Send for a Shipment-Specific Review

A reviewer needs facts about the product, package and route—not just an SDS attachment. A practical starting set includes:

• product name, manufacturer and model;
• battery manufacturer and model, if different;
• chemistry, nominal voltage, rated Ah or mAh, Wh rating, or lithium content where applicable;
• batteries shipped alone, packed with equipment or contained in equipment;
• number of cells or batteries per item and per package;
• new, used, returned, prototype, damaged, defective, recalled or waste condition;
• state of charge when relevant;
• quantity, package count, gross and net weights, and package dimensions;
• product specification, available UN 38.3 test summary and SDS/MSDS;
• clear product, battery, inner-packing and outer-packing photographs;
• proposed packing method and visible marks or labels;
• pickup location in China, destination and final delivery point;
• intended transport mode, Incoterm and cargo-ready date.

The required set can change after the actual shipment and route are reviewed. For broader regulatory context, see the current lithium battery shipping regulations guide. Air and sea movements should then be assessed under the relevant current modal rules and operating requirements.
