# Documents

> Reference for product documents in ChemCloud

Documents are files uploaded against a product for customers to review during the approval process. They provide the technical and compliance information buyers need to evaluate and approve your products.

## Document types

| Type                          | Description                                                                   |
| ----------------------------- | ----------------------------------------------------------------------------- |
| SDS (Safety Data Sheet)       | Hazard, handling and safety information. Required for most chemical products  |
| TDS (Technical Data Sheet)    | Technical specifications, performance data and application guidelines         |
| COA (Certificate of Analysis) | Batch-specific test results confirming the product meets specification        |
| Specification                 | Product specification sheet with acceptable ranges and limits                 |
| MSDS                          | Material Safety Data Sheet (legacy format, superseded by SDS in many regions) |
| Other                         | Any additional documentation relevant to the product                          |

## How documents work

### Visibility to customers

When you upload a document against a product, it becomes visible to any customer viewing that product. Customers see your documents when they:

* Evaluate your product during the approval process
* Review a product suggestion you have sent them
* Check compliance status on an existing approval

### SDS management

The SDS is typically the most critical document for chemical products. Customers often require a current SDS before they can approve a product or place an order.

Keep your SDS documents up to date. When you upload a new version, it replaces the previous one — customers always see the latest version.

### Customer document requests

Customers can request specific documents from you directly through ChemCloud. When a customer requests a document, you will receive a notification. Upload the requested document against the product to fulfil the request.

### Required documents

Some customers set required document types as part of their approval process. If a customer requires an SDS and you haven't uploaded one, the approval will show as incomplete on their side. Uploading the required documents helps move approvals through faster.
