Stannous Chloride for Sale: Buyer’s Guide to Grades, Specifications, and Bulk Supply
If you are sourcing stannous chloride in bulk, start by confirming the chemical form, purity requirements, intended use, and packaging conditions—not just the product name. Stannous chloride is tin(II) chloride, commonly supplied as anhydrous SnCl₂ or as the dihydrate SnCl₂·2H₂O. At Azeal Materials, we help B2B buyers define these requirements and request a suitable specification, quotation, and supply plan. Product availability, minimum order quantity, lead time, and documentation should be confirmed for each inquiry.

Key Takeaways for Buyers
- Choose anhydrous or dihydrate material according to your process; the forms differ in water content and tin concentration.
- Specify the required grade and measurable limits, including assay, impurities, moisture, and physical form.
- Ask suppliers to confirm packaging, current availability, shipping requirements, and the documents available for the specific lot.
- For an accurate bulk quote, provide your destination, quantity, application, and required delivery schedule.
What Is Stannous Chloride?
Stannous chloride is an inorganic compound in which tin is in the +2 oxidation state. It is also called tin(II) chloride and is used as a reducing agent and as a source of tin in a range of industrial and laboratory processes. Buyers may encounter it in solid form or as part of a prepared solution, so the required concentration and formulation should be stated when requesting a quote.
Anhydrous and Dihydrate Forms
Anhydrous stannous chloride has the formula SnCl₂ and a formula mass of approximately 189.60 g/mol. The dihydrate, SnCl₂·2H₂O, has a formula mass of approximately 225.63 g/mol. Because the hydrate contains water of crystallization, the two forms are not interchangeable on an equal-mass basis when a process depends on active SnCl₂ or tin content.
As a theoretical comparison based on formula composition, anhydrous SnCl₂ contains about 62.6% tin by mass, while the dihydrate contains about 52.6%. These values describe the pure compounds, not a supplier’s guaranteed product assay. For purchasing and process calculations, use the actual lot specification and confirm whether results are reported on an as-supplied or dried basis.
Grades and Specifications to Compare
Grade names such as industrial, technical, or reagent grade are useful starting points, but they do not replace a written specification. Requirements and test methods can vary by supplier and application. Before ordering, agree on the product form, acceptance limits, and documentation that your quality team needs.
Common Specification Items
| Specification item | Why buyers review it | What to confirm |
|---|---|---|
| Chemical form | Determines water content and process suitability | Anhydrous SnCl₂ or SnCl₂·2H₂O |
| Assay | Supports formulation and dosing calculations | Test method, reporting basis, and acceptance limit |
| Impurity limits | May affect sensitive reactions or finished-product quality | Relevant elements or other limits required by your process |
| Physical properties | Influence handling, dissolution, and feeding | Powder, crystals, particle size, or solution concentration |
| Packaging and storage | Help protect material during storage and transport | Container type, net weight, sealing, and storage guidance |
For reference, pure anhydrous stannous chloride has a melting point of approximately 247 °C. This is a chemical reference value, not a release criterion or guarantee for a commercial lot. If a specification is important to your operation, request the applicable product documentation and confirm its test basis before placing an order.
Match the Product to the Application
Stannous chloride’s reducing properties and tin content make it relevant to different process needs. It may be used in tin plating and related surface-treatment processes, chemical synthesis, and laboratory or analytical work. The appropriate form and grade depend on the recipe, process controls, and required product quality; one grade should not be assumed suitable for every use.

For plating or surface treatment, buyers should share bath requirements, preparation method, and any limits on impurities that affect coating performance. For synthesis, confirm the required stoichiometry and whether water introduced by the dihydrate is acceptable. For laboratory use, specify the intended analytical or reagent requirements rather than relying only on a broad grade label.
A Practical Selection Framework
- Define the application. Describe the process step, required function, and whether you need solid material or a prepared solution.
- Select the chemical form. Choose anhydrous or dihydrate material based on water tolerance, concentration calculations, and handling needs.
- Write down the specification. Set assay, impurity, physical-form, and packaging requirements, including test methods where needed.
- Confirm the documentation. Ask what lot-specific documents are available, such as a certificate of analysis or safety data sheet, and confirm they match your internal requirements.
- Review logistics. Provide order quantity, destination, preferred packaging, and target delivery date so the supplier can assess the relevant supply and shipping conditions.
Common Buying Mistakes to Avoid
A frequent mistake is ordering by name alone without clarifying the hydrate form. Another is comparing prices for different grades, assay bases, or packaging configurations as if they were equivalent. Buyers can also overlook moisture control, storage conditions, or the documentation needed for internal approval.
To reduce these risks, share your specification before requesting final pricing and ask the supplier to identify any deviations clearly. If your process is sensitive to water or trace impurities, validate the proposed material against your own acceptance criteria before scaling up. Do not treat a general product description as a substitute for a confirmed lot specification.
Bulk Pricing, MOQ, and Lead Time
Stannous chloride pricing depends on factors such as chemical form, grade, order volume, packaging, destination, and current supply conditions. Minimum order quantity and lead time can also vary with the requested product and shipping route. We therefore recommend requesting a quote against a defined specification rather than relying on a generic price indication.
For a useful quotation, tell us the quantity you need, the required form and grade, destination country or port, packaging preference, and desired delivery window. If you have a target specification or existing supplier document, include it for comparison. We can then discuss available supply options and clarify any details that need confirmation before an order is finalized.
How to Evaluate a Stannous Chloride Supplier
- Can the supplier distinguish anhydrous material from the dihydrate and provide a written specification for the requested form?
- Are assay, impurity limits, test methods, and reporting basis stated clearly?
- Can the supplier explain available packaging, storage guidance, and shipment arrangements for your destination?
- Are the requested lot documents available, and can the supplier confirm the MOQ and estimated lead time for your order?
- Is the supplier willing to discuss specification alignment before you commit to a bulk purchase?
As a B2B supplier, Azeal Materials can discuss stannous chloride requirements with buyers seeking specification review, bulk supply, and export coordination. The suitable grade, documents, packaging, and schedule depend on the order details and must be confirmed during quotation. We encourage buyers to share their technical and logistics requirements early so that the proposal addresses the actual procurement need.
