Quick answer
Naphthalene is identified by CAS 91-20-3. Obtain the current SDS for the actual supplier grade or finished product, and confirm the version intended for U.S. supply. A general naphthalene sheet does not automatically cover a solution, a mixture or a mothball product with a different active ingredient.
Where should you look for a naphthalene SDS?
Use the manufacturer and product code on your container or purchase record. These verified U.S. supplier catalog references can help locate the appropriate records when the product matches:
- TCI America: naphthalene, N0885 — use its product-document search or contact the supplier for the matching U.S. SDS.
- Sigma-Aldrich: naphthalene, 147141 — identify the purchased product and obtain its document through the supplier’s resources.
These are product and document lookup references, not universal SDS downloads. If the online document is unavailable, request the current file from your own supplier. A catalog entry or its safety summary is not the complete product SDS.

What does “naphthalene” describe in your request?
The NIOSH naphthalene entry provides a general occupational chemical reference. The actual supplied product can still need more information than that name and CAS number.
| Product identified | Records to locate | Question to resolve |
|---|---|---|
| A purchased naphthalene grade | Label, supplier code and grade-specific SDS | Does the returned sheet match that material? |
| A laboratory solution containing naphthalene | Solution identifier, solvent and concentration information | Is the sheet for the solution or only its solute? |
| An industrial mixture containing naphthalene | Finished composition, ingredient records and existing product SDS | Which formulation is actually supplied? |
| A mothball or similar branded product | Original label, manufacturer and active ingredient | Is naphthalene actually the ingredient named on the product? |
A similar word in a search result is not enough to establish identity. Use the full name and identifiers from the product records, especially when the result describes a derivative or another mixture.
Is every mothball product made with naphthalene?
No. The National Pesticide Information Center identifies naphthalene and paradichlorobenzene as active ingredients used in U.S. mothballs. Check the actual label rather than selecting a naphthalene SDS solely because the item is called a mothball.
For a purchased branded product, request the manufacturer’s product-specific document. Keep its label and use instructions with the request. A laboratory reagent sheet does not establish the identity or full documentation of a consumer product with a different formulation.
Does an English SDS from a U.S. company necessarily use the U.S. framework?
Check the document itself. Supplier location and language are useful details, but neither alone identifies the regulatory version. Look at the stated framework, product identifier, revision and responsible-party entries, and ask the supplier for the version applicable to the intended U.S. supply.
For example, the public National Diagnostics SFC-40 supplier sheet lists a U.S. manufacturer address while stating an EU regulatory framework. It is a useful example of why the heading must be checked; this guide does not present it as a verified U.S.-framework SDS.
Keep the complete original document for review. The translation and U.S.-market review comparison explains why changing the language does not resolve every market question.
How can you keep the document matched to the product?
- Product: record the label name, supplier code, grade and form.
- Evidence: keep the order reference, specification and any composition information available.
- File: record the SDS filename, revision and market or language version.
- Confirmation: keep the supplier’s reply where an identifier or grade was unclear.
- Access: make the confirmed current sheet available through the workplace’s normal arrangement.
If the sheet cannot be reconciled with the label, ask the supplier to resolve the difference. Avoid replacing it with the nearest public result. The supplier-document mismatch example shows that first step.
Example: an importer has the right chemical name but the wrong market file
An importer receives a naphthalene supplier sheet in English. The product code matches the purchased grade, but the document’s stated framework is for another market. A U.S. customer asks for the appropriate SDS.
- Confirm the supplier grade and product code against the imported label.
- Ask whether a current U.S. version is available for that product.
- Retain the original file, supplier response and available technical evidence.
- If review is needed, identify the U.S. responsible party and the specific document requirements.
This is an illustrative review handoff. It does not assign a hazard category or transport classification, or suggest that the importer should simply replace the supplier’s address and issue the file.
What changes when naphthalene is part of a solution or formulation?
Describe the finished product and its constituents. For a solution, identify the carrier and concentration. For an industrial blend, gather the composition record and the matching supplier documents for the ingredients. Keep any finished-product data separate from pure-chemical reference values.
The ingredient sheet supports the assessment, but does not automatically describe the complete mixture. Follow the U.S. SDS preparation workflow for a new document. If an existing composition or supplier grade changed, use the SDS update guide to define the review.
For handling and emergency decisions, use the matched product SDS, product instructions and workplace procedures. This lookup guide is not a replacement for those documents.
When should you request authoring or a U.S. SDS review?
If you bought an unchanged product and need its document, start with the supplier. An enquiry is more relevant where you import a grade needing market review, formulate a mixture, modify a product or receive a specific document question.
Include your role, product code, whether it is a pure grade or mixture, the file’s stated market framework, available records and the recipient’s request. For example: “We import one naphthalene grade. The supplier SDS is in English but states another regulatory framework. We have the label and specification and need a U.S. review for our customer.” Keep confidential composition and account details out of the initial form.

Frequently asked questions
First identify the manufacturer and active ingredient on the original product label. A mothball product may use naphthalene or paradichlorobenzene, and a reagent sheet does not automatically describe the branded product.
Yes. Check the stated regulatory framework and product details rather than relying only on the language or supplier’s address. Request the appropriate version or define a market review.
Not automatically. Identify the carrier, concentration and solution product code, and obtain the sheet for the actual solution supplied.
Keep the complete supplier file, imported product label, grade specification, available composition information and the recipient’s exact request. Identify the U.S. responsible-party details and deadline.

What is the SDS authoring starting price?
Standard English-language SDS authoring starts at USD $99 per defined product. Review, testing, translation, localization and complex or multi-product work require a confirmed scope and quote. For an unchanged purchased product, request its existing SDS from the supplier first; this is not a paid document-download service.
