If you source lubricant additives, you will frequently be asked for or request TDS, SDS (formerly MSDS), and COA. Many buyers, formulators and procurement staff mix up these documents. They serve different purposes, and none of them can replace one another. Understanding these files helps you avoid formulation errors, shipping delays and compliance risks.

What is TDS (Technical Data Sheet)?

A TDS is a technical guide for formulators and R&D engineers. It lists typical physical properties, performance features, recommended treat rates, compatible base oils and application suggestions.

It answers: Can this additive work for my formulation?

• Typical properties: viscosity, flash point, density, active content
• Performance description: anti-wear, detergency, antioxidant capacity
• Application guidance: engine oil, marine oil, gear oil, grease

Note: TDS shows typical values, not batch-specific test results.

What is SDS (Safety Data Sheet, old name MSDS)?

SDS (MSDS) is a GHS standardized safety document with 16 sections. It focuses on hazard classification, safe handling, storage, transport, PPE, first aid and spill disposal. It is used for warehouse management, customs clearance and workplace safety compliance.

It answers: How to store, ship and handle this chemical safely?

• Hazard identification and ingredient information
• Fire fighting, leakage handling and emergency measures
• Transport classification and packing requirements

Note: SDS does NOT provide formulation guidance or performance data.

What is COA (Certificate of Analysis)?

We usually provide COA along with TDS and SDS for bulk orders. A COA includes actual test results from a specific production batch, verifying that the batch complies with agreed specifications. Key question it answers: Does this shipment meet our agreed quality standard?

It answers: Does this shipment meet our agreed standard?

Quick Comparison Table

Document	Core Purpose	Target User	Batch Specific
TDS	Technical performance & formulation guidance	Formulator / R&D engineer	No
SDS (MSDS)	Safety, handling & compliance	Safety officer, logistics, customs	No
COA	Batch quality verification	QC, procurement	Yes

When Do You Need Each Document?

• Before sampling or formulation trial: Request TDS to assess suitability
• Prior to shipment and customs declaration: Request SDS
• Upon arrival of bulk goods for inspection: Request batch-specific COA

Our Lubricant Additives and Document Support

We provide complete TDS, SDS and batch COA for our lubricant additives. Two of our hot-selling products are widely searched by formulators:

ZDDP (Zinc Dialkyl Dithiophosphate)
A classic multi-functional anti-wear and antioxidant additive. It builds a protective tribofilm on metal contact surfaces, reduces valve train wear and slows oil oxidation. Widely used in engine oil, hydraulic oil, gear oil and grease.

TBN 400 Overbased Calcium Sulfonate
High-alkali detergent additive with strong acid neutralization capacity. It controls acidic by-products from combustion, keeps pistons clean, provides rust protection, and is popular for heavy-duty diesel oil and marine cylinder oil.

If you need TDS or SDS for ZDDP, TBN 400 calcium sulfonate or other lubricant additives, please send us your inquiry. Our team will prepare full documents and quotation for your formulation project.
