Reading a TDS/MSDS

Any credible lubricant supplier should hand over two documents before you commit to an order: a TDS (Technical Data Sheet) and an MSDS (Material Safety Data Sheet, increasingly called an SDS — Safety Data Sheet). They answer two very different questions, and both matter.

TDS — does this product perform the way I need?

The Technical Data Sheet is the product's actual specification: viscosity grade, viscosity at both 40°C and 100°C, viscosity index (how stable the viscosity stays across temperature swings — higher is better), flash point, pour point, density, and the relevant performance rating (API/ACEA/JASO for engine oils, or the applicable industrial standard). This is the document you compare against your equipment's manual or your customer's technical requirement to confirm a product is genuinely suitable — not just similarly named.

What to check first: the viscosity grade and rating match what's actually needed, and the viscosity index and pour point are appropriate for your climate (a low pour point matters a lot more in a cold market than a hot one).

MSDS/SDS — is this safe to handle, store, and ship?

The Safety Data Sheet covers hazard classification, safe handling and storage instructions, first-aid measures, fire-fighting guidance, and disposal/environmental information. This is the document customs authorities, freight forwarders, and your own warehouse staff need — and increasingly, it's required documentation for import clearance in many markets, independent of any product-specific certification like SONCAP.

Red flags to watch for

• A supplier who can't produce a TDS/MSDS at all, or only provides a generic one not specific to the actual product/batch.
• A TDS with vague or rounded numbers instead of real tested values (e.g. "approximately 40" instead of a specific figure with a test method referenced).
• Missing or outdated document revision dates — formulations do get updated, and documentation should track it.

Ask before you order, not after

A legitimate supplier will send both documents on request, before any commitment. If you're evaluating Lukeron alongside other suppliers, ask for the TDS/MSDS on the specific products you're considering — we'll provide them as part of the quote, not as an afterthought once you've already paid.
