COA
Used especially for raw materials, chemicals, ceramics and production inputs to show lot or batch-level technical values. It helps the buyer review recipe fit, quality and repeat-supply continuity.
Documents
Documents we coordinate
SEAL tracks not only the product and price side of a request, but also the technical and commercial documents a buyer needs before making a decision.
SDS
Contains safe use, storage, transport and risk information. For chemicals, oils, consumables and process materials, it should be requested separately at an early stage.
Technical data sheet
Collects dimensions, performance, material, working range, compatibility or application data. When alternatives are being reviewed, this document is as important as the price.
Declaration of conformity
Shows that a product is assessed against a specific standard, regulation or manufacturer statement. It can affect decisions for machinery, valves, equipment and some components.
Warranty channel
For server, computer components and corporate hardware, warranty conditions, package status and supply channel should be read separately from the price line.
Packing data
Box, pallet, volume, weight, pieces per package and label information shape the logistics side of the offer. Asking for it only at shipment stage can create delays.
Request checklist
State document needs separately in the first request.
- Name the document type: COA, SDS, technical data sheet or declaration of conformity
- State whether it is needed before ordering or at shipment stage
- Separate language, batch or lot linkage and warranty-channel expectations
- If unsure, share the product category and intended use
