| 01 Capture the chemical basis |
Record whether the need is technical, reagent, food-contact, electronic or another named grade. Note pH, density, moisture, viscosity, particle size or trace metals only when the process actually uses those limits. |
Open. Leave blanks visible instead of filling them with a catalog default. |
| 02 Align quantity and package |
State kilograms, metric tons, liters, drums, bags, IBCs or bulk. A 25 kg bag of a dry salt is not interchangeable with an IBC of a solution even if both sit in the same product family. |
Open until pack net content and unit sit on one line. |
| 03 Request exact-product files |
Ask for safety data sheet, technical data sheet and certificate of analysis for the proposed product. TSCA, REACH, GMP or ISO statements stay attached to that product and supplier. |
Open. This site does not borrow those files as its own credentials. |
| 04 Compare delivered scope |
Place product subtotal, packaging, samples, testing, freight, duties and destination charges in one table. Optional budget is a planning range, not a published market discount. |
Open. No lowest-price or guaranteed saving is stated. |
