Tannic Acid (CAS 1401-55-4) is supplied by TCS Industries Limited for B2B procurement programs that require specification review, export documentation and repeatable commercial communication. As a Hong Kong-based trading and sourcing company, TCS focuses on project supply, import paperwork and buyer-defined quality alignment rather than finished-product claims.
> Applications
Buyer-defined formulation and procurement programs
Tannic Acid is evaluated according to the buyer’s intended application, grade expectation and market destination. Technical review normally covers identity, assay or grade, impurity profile, packaging and logistics before quotation.
Documentation-led sourcing
For regulated or quality-sensitive projects, procurement teams typically need COA, MSDS, COO where applicable, invoice, packing list and route-specific import details. TCS coordinates these points before confirming commercial supply.
Technical reference
Public chemical and pharmacopoeial references list Tannic Acid under CAS 1401-55-4. This page uses those identifiers for sourcing clarity; final suitability must be confirmed against the buyer’s own specification and destination-market rules. A 2026 chemical-registry and journal-index review context is treated as n=0 human-subject evidence because it supports identity and sourcing checks rather than clinical claims.
> Sourcing & Supply
TCS Industries Limited supports development, qualification and commercial purchasing discussions for Tannic Acid with buyers in South America, Europe, the United Kingdom, Australia, New Zealand, Mexico and Canada.
- Evaluation samples: botanical identity, assay basis and document needs are reviewed before dispatch.
- Commercial lots: repeat supply is arranged by specification, extract ratio, marker compound and destination-market requirements.
> Quality & Documentation
For plant extract sourcing, buyers usually review botanical identity, marker assay, extract ratio, solvents, carriers, microbial limits, heavy metals, pesticide residues and documentation for import or qualification.
> Packaging
Packaging is selected according to product properties, quantity, destination and buyer handling requirements. Options may include sample bottles, foil bags, HDPE containers, fibre drums, 25 kg bags or palletized export packaging. Labels and documents are checked before dispatch.
> Pricing & MOQ
Pricing is quoted by marker specification, extract ratio, packaging and destination. Samples, 25 kg packs and pallet quantities can be discussed according to project stage.
> Regulatory & Compounding Context
Tannic Acid is positioned as a plant extract or specialty ingredient for buyer-defined formulation and sourcing programs. Labeling, claims, market access and finished-product compliance must be confirmed by the buyer.

> FAQ
What is the minimum order quantity (MOQ) for Tannic Acid?
There is no fixed minimum for Tannic Acid. Orders are confirmed based on project scope, batch demand, and destination market. Contact TCS Industries Limited with CAS 1401-55-4, estimated quantity, target application, and destination country for a commercial B2B response.
What documents are available for Tannic Acid orders?
COA and MSDS are standard for commercial discussions. COO, packing list, invoice and other import-support documents can be arranged according to order scope.
Can TCS Industries Limited support Tannic Acid supply to South America?
Yes. We support B2B buyers in Argentina, Colombia, Chile, Peru, Ecuador, Uruguay, Bolivia, Brazil, Paraguay, Venezuela, Guyana and Suriname, subject to route and document review.
Do you support Europe, the United Kingdom, Australia, New Zealand, Mexico and Canada?
Yes. These destinations can be reviewed for project supply, import documents, packaging and logistics planning before quotation.
Is Tannic Acid sold as a finished medicine or consumer product?
No. TCS Industries Limited supplies B2B bulk material only. Finished-product use, claims, registration and market authorization are handled by the buyer.
What is the normal MOQ for Tannic Acid?
MOQ depends on product value, stock status, specification and destination. API projects often start from 100 g to 1 kg; excipient and ingredient projects commonly use 25 kg packs or pallet quantities.
Can you arrange samples before commercial purchasing?
Samples or evaluation quantities may be reviewed for qualified buyers after target specification, application and destination-market requirements are clarified.
How is Tannic Acid packaged for export?
Packaging is confirmed by quantity and material properties. Typical options include foil bags, HDPE containers, fibre drums, 25 kg bags or palletized export packaging.
Can buyer-defined specifications be reviewed?
Yes. Send the specification, methods, impurity limits and required documents. TCS can review feasibility before confirming quotation and lead time.
What payment terms are normally used?
Standard payment is 100% T/T before dispatch unless a different arrangement has been approved for an established commercial account.
What lead time should buyers expect?
Lead time depends on stock, batch size, document scope and destination. Available stock can move faster; made-to-order or pallet programs require longer planning.
What aliases should be used when requesting Tannic Acid?
Use the product name, CAS 1401-55-4, any pharmacopoeial or grade requirement, and the InChIKey or formula when relevant to avoid sourcing ambiguity.
