Tekstil Baskı Kalınlaştırıcıları İçin TDS, SDS ve COA Belgeleri Nasıl Okunur?

Technical Guide Supplier Document Review Updated July 2026 Direct Answer

A TDS explains the product’s technical characteristics, intended use and typical or reference specification. An SDS communicates hazard, handling, storage, exposure-control and emergency information. A COA reports the test results or conformity status for a specific production batch. Textile printing buyers should use the TDS to select a possible grade, the SDS to review safety and handling, and the batch COA to confirm that the supplied material meets the agreed quality requirements. None of these documents should be used as a substitute for sample testing and production validation.

Three Documents
Three Different Jobs

TDS, SDS and COA are related but not interchangeable. A TDS is not proof of an individual batch result. An SDS is not a product-performance specification. A COA does not explain the complete application or safety requirements. Buyers should read the three documents together and check that the product name, grade, manufacturer or issuer, test method and batch information remain consistent.

Quick Comparison

TDS vs SDS vs COA

This table explains what each document is designed to answer during supplier evaluation and bulk purchasing.

Document	Main Purpose	Typical Information	Usually Batch-Specific?	Main Buyer Question
TDS	Product selection and technical reference	Product description, appearance, typical values, test methods, applications, preparation and storage guidance	Usually no	Does this grade appear suitable for my process?
SDS	Hazard communication and safe handling	Identification, hazards, composition, first aid, handling, storage, PPE, transport and emergency information	Usually no	How should this material be handled, stored and transported?
COA	Batch-quality verification	Product and grade, batch number, test items, specification limits, actual results, release date and authorization	Yes	Does this supplied batch meet the agreed specification?

Document layouts vary between suppliers and markets. The function and traceability of the information are more important than decorative formatting.

Teknik Bilgi Formu

How to Read a TDS

Begin by confirming the product identity and application scope before comparing any technical number.

TDS Field	What to Verify	Neden Önemli?
Product name and grade	Confirm the exact CMC, CMS, sodium alginate or digital paste model.	Similar product-family names may contain different grades and application routes.
Product description	Check whether it is powder, flake or liquid and whether it is a thickener, paste or pretreatment product.	Product form affects preparation, dosage and test method.
Intended application	Confirm reactive, disperse, pigment, screen, digital or industrial use.	A product proven in one process should not automatically be transferred to another.
Görünüm	Review the stated colour, form and visual condition.	Appearance may be a basic receiving and batch-check indicator.
Viskozite	Confirm concentration, temperature, instrument, spindle or rotor and RPM.	A viscosity number without its test method is incomplete.
pH	Confirm whether pH is measured as supplied or at a stated solution concentration.	Test basis and product form affect interpretation.
Moisture or solids	Confirm whether the value applies to powder, flake or liquid material.	Moisture and solids content affect dosage and delivered active material.
Preparation and dosage	Review mixing order, hydration time, dilution and application conditions.	Incorrect preparation may create misleading trial results.
Storage guidance	Check temperature, moisture protection, container closure and storage period.	Storage conditions can affect product stability and usability.
Revision date	Confirm that the TDS is the current applicable version.	Specifications, grades or test methods may change between versions.

Typical value is not always a guaranteed batch limit.

A TDS may show a typical, reference or target value rather than the acceptance range applied to every production batch. Ask the supplier which values are guaranteed specifications and which are provided only as general technical guidance.

Güvenlik Bilgi Formu

How to Read an SDS

SDS information is primarily used for hazard communication, handling, storage, exposure control, first aid and emergency planning.

The current GHS-aligned format uses sixteen sections. OSHA requires the specified information for Sections 1–11 and 16, while the complete GHS-aligned layout also includes ecological, disposal, transport and regulatory sections.

Section	Heading	Buyer Review Focus
1	Identification	Product identifier, recommended use, supplier or responsible party and emergency contact.
2	Hazard identification	Classification, signal word, hazard statements, pictograms and precautionary statements.
3	Composition / ingredients	Substance, mixture and applicable component or concentration information.
4–6	First aid, firefighting and accidental release	Immediate response measures for exposure, fire, spill or release.
7	Handling and storage	Safe handling precautions, storage conditions and incompatibilities.
8	Exposure controls / PPE	Exposure limits, ventilation, gloves, eye protection and other protective measures.
9–10	Properties, stability and reactivity	Relevant physical properties, stability, incompatibilities and hazardous decomposition.
11	Toxicological information	Routes of exposure, symptoms and available health-effect information.
12–15	Ecology, disposal, transport and regulations	Environmental, waste, shipping and applicable regulatory information.
16	Other information	Preparation date, revision date and other document information.

SDS and MSDS usually refer to the same document family.

“MSDS” is the older term still used by some buyers and suppliers. “SDS” is the current GHS-aligned term. A change from MSDS to SDS does not turn the document into a product specification or batch COA.

Certificate of Analysis

How to Read a Batch COA

The COA should connect the supplied material to a specific product, batch and set of applicable test results.

• Product name and exact grade
• Batch or lot number
• Manufacturing or release date where applicable
• Expiry or retest information where applicable
• Each applicable test item
• Specification or acceptance range
• Actual numerical result where available
• Test method or method reference
• Release or conformity status
• Authorized approval or signature
• Document issuer or responsible laboratory
• Revision or document-control information

The batch number is the traceability link.

The batch number on the COA should match the supplied packaging, invoice, packing list or other applicable shipment record. A COA with no clear batch connection provides limited evidence for the material actually delivered.

Specification vs Result

How TDS and COA Values Should Relate

Test Sorusu	TDS Reference or Specification	COA Batch Result	Buyer Check
Görünüm	White to off-white powder	Conforms	Confirm that the result uses an agreed visual criterion.
Viskozite	45,000–55,000 mPa·s under a defined method	50,200 mPa·s	Confirm that TDS and COA use the same concentration, temperature, spindle and RPM.
pH	6.5–8.0 at a defined concentration	7.2	Confirm the solution concentration and test basis.
Nem	Maximum 10.0%	7.4%	Confirm units and whether the limit applies to the supplied product form.

Product Identity

Match the Product Across All Documents

Document consistency is easier to evaluate when the same product identity is visible across the quotation, sample, TDS, SDS, COA and shipment records.

Information That Should Match

• Product family
• Exact product or model code
• Product form
• Applicable use or grade
• Batch number where relevant
• Supplier or manufacturer relationship

Information That May Differ

• TDS revision date
• SDS revision date
• Document language
• Responsible party required by the destination market
• Batch-specific COA results
• Certification or laboratory issuer

Different issuer names do not automatically mean the document is invalid.

A brand, legal company, original manufacturer, testing laboratory, distributor or certification body may appear on different documents for different reasons. The important question is whether the issuer’s role, product scope and batch relationship are clear and verifiable.

Document Issuer

Why the Original Issuer Should Be Preserved

A technical or compliance document should continue to identify the entity responsible for issuing the information. Removing or replacing the original company, laboratory or certification-body name can make the document difficult to verify and may misrepresent who performed the testing or issued the certification.

Brand Presentation

The website, quotation or document cover may identify the international business brand used for customer communication.

Original Document Issuer

The original SDS, COA, test report or certificate should retain the responsible manufacturer, laboratory, certification body or other issuing entity shown on the source document.

Verify the role instead of forcing every document to use one name.

Buyers should be able to identify who supplies the product, who manufactures or tests it, who issued the document and which batch, product or certification scope the document covers.

Product-Specific Review

What to Check for Four FSX Product Routes

Ürün Yolu	Important TDS Fields	Important COA Fields	Main Review Risk
CMC	Viscosity method, concentration, DS, pH, moisture, purity and recommended application	Batch viscosity, pH, moisture and other agreed control items	Comparing grades only by viscosity while ignoring DS and purity
CMS	Product form, printing route, viscosity, pH, preparation method and grade direction	Batch appearance, viscosity, pH and applicable quality items	Treating reactive, disperse and specialty CMS as one universal product
Sodyum Aljinat	HV, MV or LV route, concentration, viscosity method, pH, moisture and reactive-printing use	Batch viscosity, pH, moisture, appearance and agreed indicators	Treating HV, MV and LV as quality rankings instead of grade routes
Dijital Baskı Macunu	DP-R, DP-D or DP-P, powder or liquid form, dosage, pH, pretreatment and fixation route	Batch appearance, pH, solids or other product-form-specific indicators	Comparing screen-printing and digital-pretreatment data directly

For product-route selection, review the CMC, CMS, sodium alginate and digital printing paste comparison guide .

For process-based selection, review the reactive, disperse, pigment and digital printing thickener guide .

Common Document Problems

Eight Warning Signs Buyers Should Review

Missing product grade

A general family name may not identify which grade, viscosity route or application the document actually covers.

Viscosity without method

A value without concentration, temperature, instrument, spindle and RPM cannot be compared reliably.

COA without batch number

The document cannot be clearly connected to the supplied production batch.

TDS used as batch proof

A general specification sheet does not prove that one shipment was tested and released.

SDS used as performance proof

Safety and handling information does not confirm colour yield, viscosity stability, wash-off or application suitability.

Outdated revision

An older document may use a previous product description, specification, address or regulatory format.

Altered issuer details

Removing the original issuer may prevent verification of the laboratory, manufacturer or certification source.

Certificate without scope

A certificate should not be assumed to cover every product, factory, site or batch unless its stated scope confirms this.

Alıcılar İçin Sık Sorulan Sorular

Sık Sorulan Sorular

What is the main difference between a TDS and COA?

A TDS normally describes the product grade, intended use and reference or typical specification. A COA relates to a specific batch and reports the applicable test results or conformity status for that batch. Is an SDS the same as an MSDS?

MSDS is the older term still used in some markets. SDS is the current GHS-aligned term and normally follows a structured sixteen-section format. Can an SDS prove that a textile thickener is high quality?

No. An SDS communicates safety, handling and hazard information. Product quality should be evaluated using the TDS, batch COA, sample testing and actual printing performance. Should every COA contain actual numerical results?

Numerical tests should normally show numerical results where applicable. Some visual or qualitative tests may be reported as conforming to an agreed requirement. The reporting format should still be clear and traceable to the batch. Can two suppliers’ TDS viscosity values be compared directly?

Only when the concentration, temperature, instrument, spindle or rotor, RPM, preparation method and units are consistent. Otherwise, the values may not be comparable. Why might the company name differ between documents?

Different documents may identify a brand, legal entity, original manufacturer, testing laboratory, distributor or certification body. The relationship and issuing role should be clear, and the original issuer should remain identifiable. Does a COA guarantee printing performance?

No. A COA confirms applicable batch-test results, but final printing performance also depends on fabric, dye or ink, recipe, equipment, fixation and production conditions.
