A chemical supplier should provide, at minimum, a current GHS-format Safety Data Sheet, a lot-specific Certificate of Analysis, a technical or product data sheet, DOT shipping papers carrying the correct UN number and packing group, and a bill of lading. Buyers in food, pharmaceutical, export, or audited industries should also expect specification sheets, regulatory statements, and country-of-origin documentation.
What documents should come with every chemical shipment?
Five documents form the baseline. If a supplier cannot produce all five on request, that is a sourcing risk before it is a paperwork problem.
| Document | What it establishes | Who requires it | When you should have it |
|---|---|---|---|
| Safety Data Sheet (SDS) | Hazards, handling, exposure controls, first aid, disposal | OSHA Hazard Communication Standard, 29 CFR 1910.1200 | At or before first shipment, and again whenever it is revised |
| Certificate of Analysis (COA) | Measured test results for the specific lot you received | Your quality system; mandatory in regulated industries | With the shipment, tied to the lot number on the container |
| Technical / product data sheet | Typical properties, applications, storage guidance | Engineering and process teams | During specification, before you order |
| Shipping papers | Proper shipping name, UN number, hazard class, packing group, quantity | DOT hazardous materials regulations, 49 CFR Part 172 | Accompanying the vehicle at delivery |
| Bill of lading | Contract of carriage, quantity shipped, consignee | Carrier and receiving | At delivery, matched against the purchase order |
What is a Safety Data Sheet and when must you receive one?
An SDS is a 16-section document in a standardized GHS order, required under the OSHA Hazard Communication Standard, 29 CFR 1910.1200. Chemical manufacturers and distributors must provide it, and employers must keep it readily accessible to employees in their work area during each work shift.
Three points buyers commonly get wrong:
- An SDS is product-specific, not lot-specific. It does not tell you what was in the drum you just received — that is the COA’s job.
- The section order is fixed, so you can go straight to what you need. Our walkthrough of how to read a Safety Data Sheet, all 16 sections explained covers what belongs in each one.
- You are entitled to a current SDS. Ask suppliers how they push revisions out to customers rather than waiting for you to ask.
RightPath publishes documents for the products we distribute in our SDS library.
What does a Certificate of Analysis actually prove?
A COA reports the analytical results for one specific production lot against the product specification. It is the document that connects the material physically in front of you to a set of numbers you can audit. It should carry the lot or batch number printed on the container, the test methods used, the specification limits, and the measured results.
A COA is not interchangeable with a specification sheet. A spec sheet says what the product is supposed to be; a COA says what this lot measured. For how to interpret the fields, see what a Certificate of Analysis is and how to read one.
What shipping documents are required for hazardous chemicals?
Hazardous materials moving in commerce require shipping papers under 49 CFR Part 172. The description must include the proper shipping name, hazard class or division, UN identification number, packing group, and quantity, in the prescribed sequence. Emergency response information and a 24-hour emergency contact number must be available as well.
At the receiving dock, three things should agree: the container label, the shipping papers, and the SDS. If the UN number on the paperwork does not match the placard or the label, stop and resolve it before unloading. Our guides to DOT hazmat classes for solvents and reading a GHS label on a chemical drum cover both sides of that check.
Which additional documents do regulated buyers need?
- Compendial grade statements — USP, NF, FCC, or ACS conformance, where your process specifies a pharmacopeial or food-grade standard.
- Certificate of Origin — country of manufacture, needed for customs, tariff classification, and some customer contracts.
- Regulatory status letters — TSCA inventory status, REACH registration status for European supply chains, or state-level requirements such as California Proposition 65 warnings.
- Kosher, halal, allergen, GMO, and BSE/TSE statements — routine requests in food, beverage, nutraceutical, and personal care manufacturing.
- Continuing guarantee — a standing statement covering conformance across shipments, common in food-contact supply.
- Supplier quality documentation — ISO certificates, quality manuals, or completed supplier questionnaires for your approved vendor list.
Ask for these during qualification, not during an audit. A supplier who keeps them organized will produce them in a day; one who does not will take weeks.
How long do you have to keep chemical documents?
Under OSHA’s records access standard, 29 CFR 1910.1020, each employee exposure record must be preserved and maintained for at least thirty years. Safety Data Sheets indicating that a material may pose a hazard to human health fall within the definition of an employee exposure record, though the standard permits some flexibility where a record of the chemical’s identity, where it was used, and when it was used is retained for that period instead.
Retention periods for COAs and other quality records are set by your own quality system and by any industry regulation that applies to you — they are not set by OSHA. Decide those periods deliberately and write them into your document control procedure.
What documentation does RightPath Industries provide?
RightPath Industries is a Pittsburgh-headquartered distributor of more than 8,000 chemicals and a top-10 U.S. ethanol distributor. With every order we supply the current Safety Data Sheet, a lot-specific Certificate of Analysis, and compliant shipping documentation for regulated materials. Grade-specific and regulatory statements are available on request during qualification.
Our catalog spans high purity analytical solvents through commodity volumes — for example bulk acetone — and current documents are posted in the SDS library.
How do you request documentation and pricing?
Send the product, grade, packaging, and volume, plus any document set your quality system requires, and we will return an all-in delivered quote with the paperwork attached. Request bulk pricing.
Frequently asked questions
Is a Safety Data Sheet the same as a Certificate of Analysis?
No. An SDS describes the hazards and safe handling of a product and is the same for every lot. A COA reports measured analytical results for one specific lot and is different for every batch. You need both: the SDS for safety and compliance, the COA for quality acceptance.
Can a chemical distributor refuse to provide a Safety Data Sheet?
No. Under 29 CFR 1910.1200, chemical manufacturers, importers, and distributors must provide Safety Data Sheets for hazardous chemicals to downstream users. If a supplier will not produce a current SDS, that is a compliance failure on their side and a reason to source elsewhere.
What should I check on a Certificate of Analysis before accepting a delivery?
Confirm four things: the lot number matches the container, every reported result falls inside the specification limits, the test methods are the ones your specification calls for, and the document is signed or authorized by the issuing laboratory. Any mismatch should be resolved before the material enters your inventory.
What documents does an auditor typically ask for?
Auditors commonly request current SDSs for every chemical on site, lot-traceable COAs for materials used in production, evidence that employees can access SDSs during their shift, your supplier approval records, and your document retention procedure. Assembling these once and keeping them current is far cheaper than reconstructing them under audit.
Do I need documentation for non-hazardous chemicals?
Shipping papers under 49 CFR Part 172 apply to hazardous materials, so a non-hazardous product will not carry them. You should still obtain a product data sheet and a COA for quality acceptance, and most suppliers will issue an SDS regardless of classification.
