Specifications, equivalents and supplier documents
Documents that apply to any chemical product: writing specifications, approving substitutes and equivalents, and reading TDS, SDS and certificates of analysis.
Basics
-
How long do you have to keep safety data sheets on file?
Keep a safety data sheet while the chemical is in use; OSHA then requires the sheet or an identity record for 30 years. See the EU and GB rules too.
-
Do you need a safety data sheet for a non-hazardous chemical?
A non-hazardous chemical needs no SDS under OSHA, but EU rules require one on request for some unclassified mixtures. See the conditions and exemptions.
-
Does a safety data sheet expire? Update rules by jurisdiction
A safety data sheet has no expiry date, but suppliers must revise it when hazard data change. See the update deadlines under OSHA, REACH and WHMIS rules.
What goes wrong most often
-
Why do corrective actions fail to stop the same complaint?
Corrective actions fail when no cause link is named, containment is taken as the fix, or success criteria are set after results. Find which one applies.
-
Customer complaints up: is it product quality or better logging?
More logged complaints can mean a product change, new recording habits or more customers covered. Check type mix, who logged it and rate per volume.
-
Is a recurring problem the same one coming back, or a new one?
A recurring problem is the same one when the cause the last fix targeted is still there. Compare symptom, lot, conditions and timing to tell old from new.
-
Why isn't our chemical quote comparable to a competitor quote?
Chemical quotes stop being comparable when the price unit, concentration basis, pack size, tax or Incoterms differ. See how to spot and restate each basis.
-
Why do seals fail when the compatibility chart says compatible?
Seals rated compatible on a chart fail when temperature, concentration, contact time or elastomer compound differ from the test. See how to tell which.
-
We fixed this before: why didn't the same fix work this time?
A past fix fails again when a condition it relied on has changed, or when it only paused the symptom. See how to tell which, condition by condition.
-
Why was our tender non-compliant with every document attached?
Tender bids with every document attached still fail for expired certificates, wrong-grade TDS or conflicting values. See how to find and fix the cause.
-
Why does a product that meets the TDS specification fail on site?
A product can match its TDS and still fail on site because TDS tests use lab conditions. Check substrate, water, temperature, dilution and contamination.
How to choose
-
When Should a Distributor Escalate an Issue to the Manufacturer?
Keep a technical issue in house when your own tests close it and the customer can wait; escalate to the manufacturer when the product itself is suspect.
-
Is ChatGPT safe for confidential customer technical documents?
ChatGPT is safe for confidential technical documents only if it does not train on your inputs, reader scope is set first and unverified values are marked.
-
Is an SDS portal better than email for SDS and service reports?
Use a customer portal for SDS and service reports that get revised or withdrawn; email still covers the SDS copy rules require with the first shipment.
-
Is it safe to let an AI agent send emails to customers?
Only with approval first: an AI agent can email customers safely when a person approves each send, its access is scoped and every send is logged.
-
Can ChatGPT answer from my company's technical documents?
Only if the documents are attached, kept in a project or connected through company knowledge on ChatGPT Business, Enterprise or Edu, and cited by revision.
-
How do you find a replacement for a discontinued chemical?
Start from the job the discontinued chemical did: match its specification if it was bought to one, or test candidates under the customer's conditions.
-
What are the risks of formulation changes, and how do you decide?
Move a customer to a new formulation only after a trial beats the current product on agreed criteria. Late effects and reversal cost decide when to stay.
-
How do you decide whether to discontinue a low-volume product?
Drop a low-volume product only when no customer approval depends on it and switching costs are low; otherwise keep it or offer a substitute. See the table.
-
Can a chemical product be used after its shelf life has expired?
Only if it was stored as directed and passes a retest against the current specification. The manufacturer extends shelf life; the customer decides on use.
-
What do you do when a chemical trial result only partly passes?
Approve a partly passed chemical trial fully, conditionally within tested conditions, or reject it, by type of miss. Decision table and a findings record.
-
When does a chemical product reorder need requalification?
Repeat a chemical reorder when only quantity, timing or delivery changes; evaluate the product again when process, substrate, use or specification change.
-
Does a product approval still hold after the SDS is revised?
Only if the revised SDS leaves composition, hazard classification and the properties your approval used unchanged. See which sections to re-check and how.
-
How do you assess supplier risk when changing a raw material?
Proceed with a raw material supplier change when spec, trials and customer approval terms clear; stage it when customers need notice or requalification.
-
A customer asks for our full formulation: what must we disclose?
A customer asking for your full formulation gets what the SDS rules require. Other data stays a trade secret unless an NDA covers it. See what to give.
-
Trial passed on one line: can the product be approved plant-wide?
Only if the other lines match the trial line in material, equipment and operating conditions. Otherwise the approval covers only what the trial tested.
-
What should a chemical distributor track that a CRM does not?
A CRM tracks deals, contacts and pipeline. A chemical distributor also needs site conditions, products in use, visit findings and technical documents sent.
-
What should you leave out of a technical report for a customer?
Leave internal review history, confidence scores, internal sources and other customers' data out of a customer report. Add cost or margin only if needed.

-
How do you find a root cause when the customer gives no data?
With almost no customer data, ask once for missing facts, use labelled public and typical values, and mark any cause you cannot confirm as unconfirmed.

-
How do you avoid confirmation bias in a root cause investigation?
List rival hypotheses, fix what would disprove each before testing, and log every excluded cause with its scope so a root cause investigation stays open.
-

Give each quotation price and lead time a source and as-of date, set a calendar expiry, recheck old values and mark unconfirmed ones instead of guessing.
-
