Sourcing checklist

TOTM bulk plasticizer items to close before the inquiry leaves the desk

This checklist turns a totm bulk plasticizer request into specification, document and approval questions. It is not a sustainability statement, carbon inventory or factory audit. Plasticizer Sourcing uses it so bulk quantity, tank or isotank limits, assay and exact-product files are visible before factories are asked to quote.

Checklist blocks

Specification, documents and approvals for totm bulk plasticizer

Bulk TOTM checklist board beside sealed isotank fittings and sample jars

Specification lock

Write chemical name, CAS if known, trimellitate identity, viscosity, density, color, acid value, moisture, flash point and the intended medical-tubing, wire, or high-temperature PVC duty. If the buyer only knows “TOTM,” keep molecular-weight and residual-alcohol questions open instead of inventing a grade.

Bulk logistics lock

State whether the destination can receive isotank, railcar or tank-truck, heating needs, nitrogen pad, heel policy and winter pourability. Bulk TOTM is not interchangeable with drummed TOTM until net fill and receiving equipment match.

Document lock

Request current SDS, TDS and CoA format for the quoted lot. Ask TSCA status for US supply and REACH status only where the destination requires it. Those answers stay with the supplier and product.

Progress the buyer still owns

Checklist completion is a buyer record, not a plant approval. Laboratory compatibility, EHS storage, regulatory listing and commercial award remain outside this website. Optional budget should name currency and whether it is per metric ton or for the whole bulk lift. High-end, mid-range, budget or undecided is a preference, not a verified factory rating.

Open questions

Items that stay unresolved until the quoted TOTM is identified

A sheet written for a related trimellitate, a different residual-alcohol profile or another manufacturer is not evidence for the bulk lot on the quotation. Ask for the current SDS bound to the quoted identity, including flash point and any transport class.

Only when the buyer’s finished article and qualified reviewers actually require those files. Copying medical-device language onto a general industrial bulk quote does not create compliance. This desk does not hold GMP or device registrations.

TOTM is often discussed when high-temperature permanence matters more than the lowest general-purpose ester price. Record that preference as a selection factor. Do not treat it as a performance guarantee or a savings percentage from this site.

Send the totm bulk plasticizer checklist with quantity and destination

Keep isotank heating, nitrogen pad, assay method and lot SDS open on the TOTM lift instead of treating a family trimellitate sheet as closed evidence.
