SDS (Safety Data Sheet)

A Safety Data Sheet (SDS), formerly called a Material Safety Data Sheet (MSDS), is a standardized document that provides detailed information about a chemical product’s properties, hazards, handling precautions, storage requirements, and emergency response procedures. The SDS format is mandated by OSHA under the Hazard Communication Standard (HCS 2012, aligned with the Globally Harmonized System of Classification and Labelling of Chemicals, or GHS) and contains 16 required sections. Every chemical product manufactured, imported, or sold in the United States must have an SDS available for workers, handlers, and emergency responders.

The 16 Sections

Each SDS follows a fixed structure. Section 1 identifies the product and the manufacturer. Section 2 covers hazard identification, including GHS classification, signal words (Danger or Warning), hazard statements, and pictograms. Section 3 lists the composition and individual ingredients, with CAS (Chemical Abstracts Service) numbers for each component. Section 4 provides first-aid measures. Section 5 covers firefighting measures. Section 6 addresses accidental release and spill cleanup.

Section 7 details handling and storage conditions, including temperature ranges and incompatible materials. Section 8 specifies exposure controls and personal protective equipment (PPE). Section 9 covers physical and chemical properties: appearance, odor, pH, flash point, boiling point, vapor pressure, and density. Section 10 addresses stability and reactivity. Section 11 provides toxicological information. Section 12 covers ecological information. Section 13 details disposal considerations. Section 14 contains transport information, including UN Number, proper shipping name, hazard class, and packing group. Section 15 covers regulatory information. Section 16 includes revision dates and other miscellaneous information.

SDS and Amazon Hazmat Review

For Amazon FBA sellers, the SDS is the primary document Amazon uses to determine whether a product qualifies as hazardous material and, if so, how it can be stored and shipped within the FBA network. When Amazon flags a listing for hazmat review, the seller must upload the product’s SDS (or a signed exemption sheet confirming the product is not hazardous). Amazon’s hazmat team reviews Section 2 (hazard classification), Section 9 (physical properties, particularly flash point), and Section 14 (transport classification) to make their determination.

Products with a flash point below 200 degrees Fahrenheit (93.3 degrees Celsius) are commonly classified as flammable and face FBA storage restrictions. Aerosol products, perfumes, nail polish, alcohol-based sanitizers, and many cleaning products fall into this category. Amazon may approve these products for FBA with special handling requirements, restrict them to specific fulfillment centers, or reject them from FBA entirely depending on the hazard level.

Common Problems Sellers Face

The most frequent SDS-related issue for Amazon sellers is not having an SDS at all. Many private-label sellers source products from overseas manufacturers and never request the SDS during the sourcing phase. When Amazon flags the product months later, the seller scrambles to obtain the document from a factory that may take weeks to respond. Requesting the SDS before placing the first production order prevents this bottleneck.

Another common problem is an SDS that does not match the product being sold. If a seller sources a hand sanitizer and the SDS they have on file is for a different formulation, concentration, or fragrance variant, Amazon may reject it. The SDS must correspond to the exact product listed on the ASIN.

Incomplete or non-GHS-compliant SDS documents also cause rejections. Amazon requires the full 16-section GHS format. Older MSDS documents in the previous 8-section or 16-section (non-GHS) format may not be accepted.

SDS in Warehouse Operations

Any warehouse storing chemical products must maintain SDS files accessible to all workers who may come into contact with those products. This is an OSHA requirement, not optional. Prep centers handling products that have SDS classifications must ensure their staff understands the handling requirements, appropriate PPE is available, and the SDS files are current. MeisterPrep reviews SDS documentation for products flagged as potentially hazardous, ensuring proper handling during the prep process and correct labeling for outbound shipment to Amazon or other destinations.
