DMA 40%: A Clear Handoff from Purchasing to Production
2026-11-12
China Amines Co., Limited
A shipment of dimethylamine 40% aqueous solution has arrived. Purchasing has the order confirmation, quality has the COA, and production needs to know when the material is available.
For customers coordinating supply with China Amines Co., Limited, a concise material handoff record helps connect these separate pieces of information.
Start with one agreed product description
Record the full product name, supplier grade, internal material code, and approved specification revision.
Identify the required concentration as a weight-based value. Manufacturer specifications for DMA 40% describe the aqueous grade and its assay requirements, providing the context needed to interpret batch results.
Keep the same description across purchasing, receiving, and production records.
Pass on the batch-specific information
A useful handoff record includes:
| Information | Purpose |
|---|---|
| Supplier batch number | Connects material with supporting records |
| Accepted assay | Supports batch-specific content calculations |
| Received net solution weight | Establishes the recorded product quantity |
| Inspection and release status | Shows availability under the site procedure |
| Storage location | Identifies where the material is held |
Attach or link the relevant COA. Manufacturer documentation systems commonly retrieve certificates using lot or batch identifiers.
Keep quantity calculations identifiable
Separate solution weight from calculated contained DMA.
For example, 5,000 kg of solution at exactly 40.0% w/w contains 2,000 kg of DMA. Label the concentration basis and calculation clearly.
If production uses an accepted assay that differs from the nominal value, retain that input with the calculation. Any process adjustment should follow the responsible technical team’s approved instructions.
Make outstanding actions visible
Record missing documents, pending tests, or unresolved questions with an owner and expected update.
Distinguish physical arrival from quality release so production planning reflects the material’s current status. If a delivery date or accepted quantity changes, update the shared record and notify the affected teams.
Coordinate your next DMA 40% delivery
Send China Amines Co., Limited your approved specification, required net quantity, packaging preference, destination, and production need date.
Include the batch documentation and receiving information your team needs to prepare a clear handoff.
