MSDS (Material Safety Data Sheet)

An MSDS, or Material Safety Data Sheet, is a document that provides detailed information about the chemical composition, physical properties, health hazards, handling procedures, and emergency response measures for a specific product. The term MSDS has been largely replaced by SDS (Safety Data Sheet) following the United Nations’ Globally Harmonized System (GHS) of Classification and Labelling of Chemicals, but the older acronym remains widely used in industry conversation and many Amazon seller workflows still reference MSDS when describing hazmat documentation requirements.

What an SDS Contains

Under GHS, a Safety Data Sheet must include 16 standardized sections. These are not optional or customizable. Every SDS follows the same structure worldwide.

Section 1 covers product identification, including the product name, manufacturer, and emergency phone number. Section 2 lists hazard identification, including GHS classification, signal words (Danger or Warning), and hazard statements. Section 3 details the chemical composition. Sections 4 through 8 cover first aid measures, fire-fighting measures, accidental release measures, handling and storage requirements, and exposure controls. Section 9 provides physical and chemical properties such as flash point, boiling point, and vapor pressure. Sections 10 through 16 cover stability, toxicology, ecological information, disposal considerations, transport information, regulatory information, and any other relevant data.

The transport information in Section 14 is particularly relevant for logistics operations. It includes the UN number, proper shipping name, transport hazard class, packing group, and any special transport precautions. This is the section that customs brokers, freight forwarders, and carriers reference when determining how a product must be handled during shipment.

SDS in Amazon FBA

Amazon requires an SDS for any product that contains chemicals, batteries, or materials that might be classified as hazardous. This includes obvious items like cleaning products and pesticides, but also less obvious ones like cosmetics, essential oils, certain food supplements, and any product containing lithium batteries.

When a seller lists a product that triggers Amazon’s hazmat review, the system requests an SDS. The seller must upload a compliant SDS to proceed with the listing. Amazon’s hazmat review team evaluates the document to determine whether the product can be stored in standard fulfillment centers, requires hazmat-designated storage, or is prohibited from FBA entirely. Products with a flash point below 100 degrees Fahrenheit, for example, face additional restrictions.

The SDS must match the exact product being sold. A seller cannot upload a generic SDS for “lavender essential oil” if their specific product has a unique formulation. The product name, manufacturer, and chemical composition on the SDS must correspond to the product listing. Mismatched documents result in listing suppression until a correct SDS is provided.

Who Creates an SDS

The manufacturer or formulator of a chemical product is responsible for creating the SDS. If you are selling a product manufactured by another company, the manufacturer must provide you with the SDS. If you are private-labeling a product (putting your brand on someone else’s formulation), your contract manufacturer should provide an SDS that reflects your product name and brand information.

SDS documents must be updated whenever the product formulation changes, new hazard information becomes available, or regulations are amended. There is no fixed expiration date for an SDS, but documents older than 3 to 5 years are often flagged as potentially outdated by buyers and regulatory inspectors.

Operational Considerations

Warehouses and prep centers that handle products requiring an SDS must maintain copies accessible to all employees who might encounter the products. OSHA requires that SDS documents be available during every work shift to any worker who requests them. This can be managed through physical binder systems at workstations or through digital SDS databases accessible on warehouse terminals.

For FBA prep operations, having the SDS on file before receiving a product is a best practice. MeisterPrep and similar prep services typically request the SDS as part of the client onboarding process so that any special handling, storage, or labeling requirements are identified before the product arrives at the warehouse. This prevents delays caused by receiving a shipment that cannot be processed because the necessary hazmat documentation was never provided.
