NAC Product Details
NAC Content & Purchasing Basis
Specify the assay basis in your purchase requirement so the quotation and quality approval use the same definition.
Dried-Basis Assay
For purchases specified on a dried basis, state that basis alongside your required assay range. Confirm the applicable method and reporting terms with the supplier, and use the same requirement for quotation, material approval and receiving.
As-Is Assay
If your purchasing or formulation requirements use an as-is assay, include that requirement separately in your specification. Confirm the offered lot's reported basis and test method with your quality team before approving the material.

NAC Powder for Your Production Process
Evaluate the powder in your own process before confirming a production specification.
Particle Size & Powder Handling
The sieve specification is listed in the product details and COA. For capsule filling, compression or premix production, share any additional particle size, flow or bulk density requirements. Confirm these separately rather than relying on the mesh result alone.
Odor & Finished-Formula Evaluation
NAC has a characteristic odor recorded in the specification. For powder blends or drink-mix projects, include odor and taste acceptance in your sample evaluation. Assess the ingredient with your other components and intended packaging.
Documents for NAC Material Approval
Tell us which supporting records your quality team requires for this NAC specification.
Lot-Specific COA
Request the COA for the offered lot, with both assay bases identified. Match the lot number and dates to your purchasing and receiving records.
Additional Test Requirements
Send any related-substance, solvent or other limits beyond the listed specification. Confirm available methods and supporting records before material approval.
Handling & Destination Documents
Request the SDS for the supplied material and identify any origin or other declarations needed by your import team. Availability is confirmed for your order.
NAC Packaging & Material Protection
25 kg Drum Supply
NAC is supplied in 25 kg drums. Confirm the inner packaging and closure for your order, including any light- or moisture-protection requirements. Check drum and inner-pack condition on receipt, and retain the batch identification with your stock.
Storage Between Production Runs
Keep sealed in a cool, dry place, away from heat, light and moisture. Reseal the inner packaging and drum after dispensing to limit exposure during storage. Follow the supplied handling instructions and batch expiry date.
