In short: what is an MSDS/SDS and do you need one?

An MSDS (Material Safety Data Sheet), now formally called an SDS (Safety Data Sheet) under the Globally Harmonized System, is a standardised document describing a product's chemical composition, hazards, handling instructions, and safe transport requirements. If you're importing products into Ireland that contain chemicals, batteries, aerosols, or certain cosmetic ingredients, customs and freight carriers will ask for one before goods can ship or clear. It is not the same as a Certificate of Origin or a Certificate of Analysis, and Irish importers under EU REACH and CLP rules have extra obligations beyond just holding the document.

What is the difference between an MSDS and an SDS?

They're effectively the same document under different names. MSDS was the older, US-style term; SDS is the standardised 16-section format required under the UN's Globally Harmonized System (GHS), which the EU has adopted through the CLP Regulation. Chinese suppliers may still label the document "MSDS" out of habit, but for EU and Irish compliance purposes, you need the GHS-format 16-section SDS, not an older-style MSDS that skips sections.

Which products need an MSDS/SDS when importing from China to Ireland?

When in doubt, ask your supplier directly whether the product classifies as a "dangerous good" or "hazardous substance" for freight purposes — this determines both the paperwork and the shipping method available.

How is an SDS different from a Certificate of Origin or COA?

These three documents are commonly confused but serve completely different purposes:

• SDS/MSDS — covers chemical hazards, handling, and safe transport of the product itself
• Certificate of Origin — confirms which country the goods were manufactured in, used for customs and preferential tariff claims
• Certificate of Analysis (COA) — confirms a specific batch meets stated purity, composition, or quality specifications, common for cosmetics and supplements

Many shipments need more than one of these simultaneously. A private label skincare order from China to Ireland, for example, typically needs an SDS, a COA per batch, and product certifications relevant to EU cosmetics rules.

What do Irish importers need beyond a basic SDS?

Under EU REACH (chemical registration) and CLP (classification, labelling, packaging) regulations, Irish importers of chemical-containing products carry legal responsibilities that go beyond simply holding a supplier's SDS on file:

• REACH registration — required if you're importing more than 1 tonne per year of a substance not already registered by someone in the EU supply chain
• CLP labelling — hazard pictograms, signal words, and precautionary statements must appear on the product or packaging in the required format
• 16-section SDS in the correct format — many Chinese suppliers provide a shortened US-style MSDS by default; you may need to request the full GHS/CLP format explicitly

Getting these requirements confirmed before production, not after the goods arrive at Dublin Port, avoids costly delays and potential customs holds.

How do you get an SDS from a Chinese supplier?

Request it in writing as part of your purchase order, specifying that you need the 16-section GHS format rather than a generic MSDS. Reputable factories that regularly export to the EU will have this on file or will commission one from a testing lab (such as SGS or Intertek) for a modest fee. If a supplier can't produce one for a product that clearly needs it, treat that as a red flag worth raising during factory verification.

FAQ: MSDS, SDS and export documentation

Is an MSDS legally required for every shipment from China?

No — only for products containing hazardous or regulated substances, such as chemicals, batteries, aerosols, and certain cosmetic formulations. Plain textiles, basic homeware, and most toys without batteries typically don't need one.

Who provides the MSDS/SDS — the supplier or the importer?

The supplier or manufacturer should provide it, since they know the exact formulation. As the Irish importer, you're responsible for confirming it meets EU CLP format requirements and for holding it on file in case customs or REACH enforcement asks for it.

Does a product need both an SDS and product certification (like CE marking)?

Often yes. An SDS covers chemical hazard and handling information; CE marking (or equivalent) confirms the product meets EU safety, health, and environmental standards for its category. See our guide to product certifications explained for how these fit together.

What happens if I ship without a required SDS?

Freight forwarders and carriers can refuse to book dangerous goods shipments without proper documentation, and customs can hold or reject a shipment at Dublin Port pending the correct paperwork — both of which cost far more in delays than sourcing the SDS upfront.

Does the SDS need to be in English for Irish customs?

Yes, alongside any other EU language requirements relevant to your specific product category. A Chinese-only SDS will not satisfy REACH/CLP documentation requirements.

How Epic Sourcing helps

Epic Sourcing works with Irish importers to confirm documentation requirements, including SDS/MSDS, Certificates of Origin, and product certifications, before production even starts — with a bilingual team on the ground in China who can push suppliers for the correct GHS-format paperwork rather than a generic shortened version.
