An MSDS (Material Safety Data Sheet—now commonly referred to simply as SDS, or Safety Data Sheet) is a legal document transmitted along the chemical supply chain, compiled in accordance with the GHS (Globally Harmonized System). Regarding the question of whether hardware structural components require one: while pure metal products generally do not mandate it, provision is virtually essential in three scenarios: the presence of surface treatment agents, booking for sea or air freight, and explicit customer requirements.
This article clarifies the criteria and key points for handling this process.
I.
When must an MSDS/SDS be provided?
- The product contains hazardous ingredients: Items such as lead alloys, cadmium-nickel alloys, metal powders, or surface treatment agents containing hazardous substances are classified as chemicals or articles containing chemicals; an SDS must be transmitted along the supply chain.
- Surface contamination or treatment layers: Most hardware components are not inherently hazardous, but their surfaces may be coated with anti-rust oil or cutting fluids, or feature electroplated layers (e.g., hexavalent chromium). These components may pose risks; shipping lines and airlines require an SDS and a transport identification report to confirm the goods are “non-hazardous” before accepting bookings as general cargo.
- Customer and customs clearance requirements: An increasing number of downstream customers include the SDS in their supplier documentation packages. Furthermore, when declaring hazardous chemicals for export, General Administration of Customs Announcement No. 129 (2020) requires the submission of materials such as a Declaration of Conformity, for which the SDS serves as a crucial supporting document.
II.
Can pure metal components be exempt?
Pure metals (such as iron, copper, aluminum, and stainless steel) that lack additives or special surface treatments generally do not require an SDS.
However, industry best practice suggests providing an SDS whenever possible: first, given the trend toward supply chain transparency, having an SDS ready prevents shipment delays caused by last-minute customer requests; second, surface treatments (such as electroplating, blackening, passivation, or anti-rust oil) are common—meaning items that appear to be “pure metal” actually carry chemical agents—so if a shipment booked as general cargo is inspected and no SDS is available, the goods may be held up.
III.
SDS Preparation Requirements
Within China, SDSs are prepared in 16 sections in accordance with GB/T 16483 (*Safety Data Sheet for Chemical Products – Content and Order of Sections*) and GB/T 17519 (*Guidance on the Compilation of Safety Data Sheets*): Chemical Product and Company Identification; Hazard 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; and Other Information.
For exports to the EU, the format follows Annex II of the REACH Regulation; for exports to the US, it follows the OSHA HazCom 2012 (GHS) standard. When creating versions for multiple countries, the format and language must be adapted to the target market.

Preparation Pathways and Practical Tips
Enterprises can prepare SDSs in-house based on composition data or commission a third-party agency (with chemical classification and assessment capabilities) to prepare them, often accompanied by a transport identification report (confirming the goods are non-hazardous).
Key practical points include: first, composition information must be accurate—concealing ingredients like anti-rust oil or plating materials can lead to the rejection of the transport identification; second, the SDS must reflect the actual state of the product and be updated following any process changes (such as switching anti-rust oils or altering plating); third, having both the SDS and the “Identification and Classification Report for Transport Conditions of Goods” ready during shipping facilitates smoother booking.
Industry experts recommend including the “SDS + Transport Identification Report” in the standard documentation package for hardware exports: even if not mandatory, a compliant SDS ensures hassle-free booking, smooth customs clearance, and customer trust.
