GHS & SDS Compliance in Practice: Frequently Asked Questions for Industry

Do you still think an SDS is just another document your customers ask for?

In day-to-day operations, many companies treat a Safety Data Sheet (SDS) as a piece of "supporting paperwork": you hand it over when a client requests it, scramble to supplement it for customs clearance, or patch it up when an audit looms.

In reality, SDS management is never just about "document delivery." It is a comprehensive ecosystem that spans product hazard classification, label management, supply chain communication, transport compliance, regulatory adaptation, and risk control.

With global regulations constantly evolving, chemical labeling shifting toward digitalization, and customer audits becoming more granular, the challenge for most companies isn't that they don't know how to author an SDS. Rather, the common pitfalls are:

• They do it, but not systematically.
• They have the document, but the content lacks precision.
• They can deliver the file, but it cannot withstand scrutiny or deep technical questioning.
• They use a standard template, but lack the localization logic needed for different destination countries.

This article compiles the most frequently asked questions by enterprises regarding practical GHS and SDS compliance.

Part I: Back to Basics—What Exactly Are GHS and SDS?

01 | What is GHS?

The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is a global framework established under the auspices of the United Nations.

Its core purpose is to provide a relatively uniform, international standard for classifying chemical hazards and communicating those hazards through labels and datasheets. In short, GHS is not just a set of labeling rules; it is a universal international language for expressing chemical hazards.

02 | What is an SDS?

A Safety Data Sheet (SDS) is one of the most critical documents used to transmit chemical safety data across the supply chain.

It contains comprehensive information regarding hazard identification, composition/ingredients, first-aid measures, firefighting measures, accidental release measures, handling and storage, exposure controls/personal protection, and regulatory information.

03 | Why must companies prioritize SDS compliance?

An SDS is far more than a file used to satisfy a customer requirement. It serves as the compliance foundation for multiple facets of an enterprise, including:

• Product sales and vendor audits
• Import/export declarations and customs clearance
• Warehousing, logistics, and dangerous goods identification
• Employee training and occupational safety
• Emergency response and liability determination
• Regulatory inspections and enforcement risk management

Fundamentally, an SDS reflects a company's capability to accurately identify, evaluate, and communicate chemical hazard information.

Part II: Can One SDS Be Used Globally?

04 | Can a single SDS cover all countries?

In most cases, no.

While GHS provides a unified global framework, individual countries and regions implement it with significant local variations, such as:

• Different adopted versions of the UN GHS
• Different classification criteria and thresholds
• Different mandatory or national inventory classification lists
• Distinct labeling element requirements
• Local official language requirements

The compliant approach is to author the SDS specifically to meet the regulatory requirements of the destination country.

05 | Can the same substance have different classifications in different countries?

Yes, and this is highly common.

The primary reasons include:

• Countries adopt different revisions of the UN GHS.
• Different countries/regions have different mandatory or harmonized classification lists.
• Regulatory bodies interpret classification data differently.
• Certain hazard categories are adopted in some jurisdictions but skipped in others.

Consequently, it is entirely normal for the exact same substance to yield different classification outcomes.

Part III: Which Sections of the SDS Are Most Critical?

06 | What does a standard SDS contain?

A standard SDS contains 16 sections, including:

• Identification
• Hazard(s) Identification
• Composition/Information on Ingredients
• First-Aid Measures
• Fire-Fighting Measures
• Accidental Release Measures
• Handling and Storage
• Exposure Controls/Personal Protection
• Physical and Chemical Properties
• Stability and Reactivity
• Toxicological Information
• Ecological Information
• Disposal Considerations
• Transport Information
• Regulatory Information
• Other Information

In practice, the sections most prone to errors—and most heavily scrutinized during audits—are:

• Section 2: Hazard Identification (Classification)
• Section 3: Composition/Information on Ingredients
• Section 4: Transport Information
• Section 15: Regulatory Information

07 | Why is Section 14 (Transport Information) so critical?

Section 14 directly dictates whether a product is classified as Dangerous Goods (DG) during logistics, and how it must be legally transported.

Key elements that we shall pay close attention to are:

• UN Number
• Proper Shipping Name
• Hazard Class
• Packing Group
• Environmental Hazards / Marine Pollutant status
• Special Transport Regulations

The issue for many companies is not that they leave Section 14 blank, but that the information is imprecise, overly generic, or inconsistent with the actual physical state and traits of the product

08 | Is it acceptable to list only a broad, generic category in Section 14?

Generally, this is not recommended.

If a specific transport entry applies, the SDS should list the most precise and granular entry possible. Broad, generic categories should only be used as a temporary description when the specific use, state, or precise entry truly cannot be verified—and even then, the choice must be backed by a sound technical rationale.

09 | What information should be included in Section 15 (Regulatory Information)?

It needs to reflect the product's regulatory standing within the target jurisdiction, including:

• Whether ingredients are listed on national chemical inventories.
• Whether the ingredients involve licensing, registration, restriction, or notification obligations.
• What obligations enterprises should pay attention.
• Whether it fall under any special administrative requirements.

The accuracy of Section 15 often determines whether an SDS is genuinely usable and legally compliant in the market.

Part IV: Navigating Ingredient Disclosure

10 | Does Section 3 require disclosure of every single ingredient?

No. Whether a component must be disclosed typically depends on:

• Whether the ingredient itself is hazardous.
• Whether its concentration meets or exceeds the regulatory disclosure threshold (cut-off value).
• Whether it is a substance of high concern.
• Whether omitting it would compromise safe handling or emergency response decisions.

Therefore, component disclosure must follow strict regulatory rules rather than a company's internal preference to hide or show data.

11 | Can trace additives or processing aids simply be grouped and labeled as "Additives"?

Not universally. If a component is present in a low concentration but carries a hazard that triggers a regulatory disclosure threshold, it must be disclosed individually. Companies may only simplify these names if the ingredient triggers no disclosure obligations and does not compromise the transmission of critical safety information.

12 | How can we balance trade secrets with component disclosure?

This is a classic dilemma for many enterprises.

Several jurisdictions allow companies to protect proprietary chemical identities or exact concentrations through Confidential Business Information (CBI). However, there is a strict prerequisite: confidentiality must never compromise hazard identification, occupational health protection, emergency response, or safe use.

In short: you may protect your trade secrets, but you cannot use confidentiality as an excuse to dilute safety information.

Part V: Does "No Classification" Mean No SDS?

13 | If a product has no GHS hazard classification, is an SDS still required?

Not necessarily. This is one of the most common misunderstandings in practical cases. Even if a product as a whole does not trigger a GHS hazard classification, you may still be required to provide an SDS if:

• It contains hazardous ingredients that exceed specific cut-off thresholds.
• It contains substances of high concern or restricted components.
• Regional regulations explicitly mandate it.
• Customers or downstream supply chain partners explicitly request it.
• It presents an occupational exposure risk that requires safety management.

Therefore, "no hazard classification" does not automatically mean "no compliance obligations."

Part VI: Do Food, Cosmetics, and Metal Products Need an SDS?

14 | Do food products require an SDS?

Generally, food and food additives in their finished state ready for consumer consumption do not require a standard SDS. However, if workers face exposure risks, chemical hazards, or occupational hazards during production, compounding, warehousing, transport, or industrial downstream processing, assessment should be conducted to determine if safety info documentation is necessary.

15 | Do cosmetics require an SDS?

The logic mirrors that of food products. As finished goods packaged for consumers, cosmetics are typically exempt from SDS requirements. However, in industrial manufacturing, raw material management, bulk transport, or repackaging stages, an SDS or equivalent safety document may be required to manage chemical risks.

16 | Do metal products require an SDS?

This depends heavily on the physical form and hazard characteristics of the product, for example:

• Metal Powders: Highly susceptible to flammability, explosivity, or inhalation hazards, and absolutely require a detailed SDS assessment.
• Massive Forms (Blanks, Bars, Sheets): In stable, solid forms where no hazards are released under normal conditions, they are often exempt from standard chemical SDS management.

The trigger is not whether the material is a "metal," but whether its physical state constitutes an object that transmits hazard risks.

17 | Do empty containers or equipment parts that held chemicals require an SDS?

An SDS is authored for the chemical substance or mixture itself, not the equipment or container. However, if a container carries chemical residues that could expose handlers to risk, appropriate chemical safety information matching the residue must be provided.

Part VII: Dangerous Goods & Transportation

18 | Can small-package hazardous chemicals be shipped directly as regular cargo?

No. Whether a shipment qualifies for Limited Quantities (LQ), Excepted Quantities (EQ), or other transport exemptions depends entirely on the applicable transport regulations based on:

• Hazard class
• Type of packaging
• Net quantity per inner and outer packaging
• Specific regulatory entry exemptions

19 | If US does not adopt certain environmental hazard terminology, does that mean the product is not regulated as dangerous goods for transport?

No. GHS hazard classification systems and transport regulation frameworks do not have a perfect 1-to-1 correspondence. Even if terminology or classification criteria differ between systems, a product can still be designated as Dangerous Goods if it triggers the criteria set by specific transport regulations.

Transport compliance must always be evaluated directly against applicable transport regulations.

Conclusion

Ultimately, SDS compliance is not about "filling out a form"—it is a demonstration of your company's risk communication capabilities. Mature SDS management ensures that:

• Classifications are data-driven.
• Information is technically defensible.
• Labels align with the data sheets.
• Transport details are execution-ready.
• Local regulations match perfectly.
• Updates keep pace with changing rules.

The sooner an enterprise transitions its SDS strategy from a reactive delivery requirement to a proactive compliance system, the more effectively it mitigates legal, operational, and financial risks.
