The MSDS/SDS a battery shipment needs
Everyone still says MSDS. What has to arrive is a sixteen-section SDS, and most of what gets sent is neither.

The sixteen sections, and the three that matter to you
The structure is fixed and numbered: identification; hazard identification; composition; first-aid measures; fire-fighting measures; accidental release measures; handling and storage; exposure controls and personal protection; physical and chemical properties; stability and reactivity; toxicological information; ecological information; disposal considerations; transport information; regulatory information; and other information.
Section 1, identification. The product name, the identifier and the supplier. This is where you check that the document is about the model you are buying and that the company named is the company invoicing you. A sheet for "lithium ion battery" in general is not a sheet for your product.
Section 14, transport information. The UN number, the proper shipping name, the class and packing group where applicable, and any special provisions. This is the section a freight forwarder reads and the section that has to agree with how the consignment is actually being classified. If section 14 says one thing and the booking says another, the booking is what gets stopped.
Section 2, hazard identification, plus section 9, physical and chemical properties. These are what a warehouse, an airline and an emergency responder use. A sheet with a blank or generic section 2 is a sheet nobody prepared for this product.
And check the language and the date. Destination authorities and carriers may require the sheet in a particular language, and an undated sheet — or one dated many years ago against a product launched recently — is a document that will be questioned.
What a bad one looks like, and what to do about it
The one-page summary with a logo. It is the commonest thing sent when a buyer asks for an MSDS: a single page of specifications and a safety paragraph. It is not a safety data sheet, it will not satisfy a forwarder, and asking again a week before shipment is how a schedule slips.
A sheet for the cell rather than the battery, or for a different model. Both are common and both are checkable in section 1. A cell sheet is a real document about a real product — just not about yours.
Sections missing or reordered. The order is part of the standard, so a document that omits a section or renumbers them was not produced to the standard, whatever the header says.
Section 14 disagreeing with the shipment. This is the expensive one. If the sheet describes the goods as one UN number and the consignment is booked as another, somebody has made a classification decision that the paperwork does not support — and it is worth resolving before the goods move rather than at acceptance.
What to do: ask for it at quotation, not at booking. Name the requirement in the purchase order — a sixteen-section SDS for the exact model, in the language the destination requires — and treat it as a deliverable with a date, alongside the UN 38.3 test summary.
Where it fits with the rest of the paperwork
The SDS is not a substitute for UN 38.3 documentation and does not prove the design passed anything. They answer different questions: UN 38.3 says the design survived eight transport tests; the SDS describes the hazards, the handling and the transport classification.
It is also not a certificate of compliance for a destination market. Product safety, radio approval and restricted-substance obligations are separate regimes with separate documents, and an SDS says nothing about any of them.
It travels with the shipment and lives in your files afterwards. Carriers and customs authorities ask on the day, warehouses ask when they receive, and a marketplace or a business customer may ask months later. Keep it where your team can find it rather than in a supplier's inbox in another time zone.
And update it when the product changes. A different cell chemistry, a different supplier or a changed capacity can all change what the sheet should say — which is the same clause that protects your UN 38.3 documentation, and is worth writing once to cover both.
The practical rule: the SDS, the UN 38.3 test summary and the packing arrangement are one bundle, requested together at quotation, and checked against each other for model and applicant before anything is booked. Any one of the three arriving late delays the other two.
What to ask the factory for, in one message
A sixteen-section safety data sheet for the exact model you are buying, naming the manufacturer that will invoice you, in the language your destination requires, dated within a sensible period.
The UN 38.3 test summary for the same model, signed, with the name and title of the signatory.
Confirmation of the transport classification the factory expects — the UN number and proper shipping name — so that it can be checked against section 14 and against what the forwarder books.
The packing arrangement and the marks and labels that will appear on the outer cartons, so the forwarder can confirm them before the goods are packed rather than after.
Asking for all four in one message at quotation costs nothing and removes the most common cause of a delayed lithium shipment, which is a document requested too late from a company that has to go and find it.
Questions people actually ask
What is the difference between an MSDS and an SDS?
MSDS is the older name. The current international format is the safety data sheet — sixteen numbered sections in a fixed order under the Globally Harmonized System. Suppliers and forwarders still say MSDS in daily use, but what has to be produced is a sixteen-section SDS, and the fixed structure is what makes it checkable.
Which section of the SDS does my freight forwarder read?
Section 14, transport information — the UN number, the proper shipping name, the class and any special provisions. It has to agree with how the consignment is actually being classified and booked; when it does not, the booking is what gets stopped.
How do I tell a real SDS from a summary?
Count the sections. A real one has sixteen, numbered, in the standard order. Then check section 1 to confirm the document is about the model you are buying and names the company invoicing you, and check that section 14 matches your booking. A one-page specification sheet with a safety paragraph and a logo is not an SDS.
Is an SDS for the cell the same as one for the battery?
No, and being sent the cell's sheet instead of the battery's is common. It is a real document about a real product — just not about yours. Check the product identification in section 1 against the goods on your purchase order.
Does an SDS prove my battery passed UN 38.3?
No. They answer different questions: UN 38.3 documentation says a design survived eight transport tests, while the SDS describes the hazards, the handling and the transport classification. Request both together at quotation, and check them against each other for model and applicant.
When should I ask for the SDS?
At quotation, alongside the UN 38.3 test summary, the expected transport classification and the packing and marking arrangement — as a deliverable with a date in the purchase order. A document requested at booking, from a company that then has to go and find it, is the commonest cause of a delayed lithium shipment.
