# TAD Paper Supplier Change Control: Which Specs Must Stay Locked After Sample Approval? TAD paper supplier is the primary procurement topic for this buyer guide. It is used where the wording helps define the decision, not as a repeated filler phrase. **Status:** Research draft only — not approved for publication **Author:** [Tracy Zhang](https://tissuepapersupplier.com/tracy/) **Prepared:** 2026-08-13 **Primary keyword:** TAD paper supplier **Supporting keywords:** TAD paper supplier change control, TAD paper manufacturer, TAD parent roll supplier, TAD tissue change control, TAD paper specifications, TAD roll quality control, TAD paper sample approval, TAD paper supplier audit ## TAD Paper Supplier: direct answer After sample approval, lock the grade and fiber furnish declaration, ply or construction, GSM, thickness or bulk, tensile and stretch, absorbency, optical properties where relevant, roll width, core, diameter, winding, splices, production site, key process route, test methods, packing, labeling, and certificate format. The agreement should distinguish notification, approval, and emergency changes, define lead time, identify affected lots, and require a requalification plan before changed material ships. The signed sample is only a snapshot. Change control is what keeps a later production roll connected to that decision. A TAD paper supplier should identify which material, process, site and roll-construction changes require notice before production. ## Buyer decision table | Control point | What to lock | How to verify | Risk if omitted | | --- | --- | --- | --- | | Material | Lock grade, furnish declaration and approved alternatives. | Trace declarations and production records by lot. | A substitute fiber can shift performance without changing the product name. | | Performance | Lock methods and limits for GSM, bulk, tensile and absorbency. | Use conditioned tests on the exact production grade. | Changing the method can make stable paper look different—or hide drift. | | Roll geometry | Lock width, core, OD, winding and splice rules. | Verify dimensions and run a controlled unwind. | Converter downtime often starts at the roll interface. | | Process/site | Name manufacturing and converting sites plus critical route. | Require notice and qualification for transfers or material changes. | A group-level certificate does not prove identical site output. | | Packing | Lock wrap, edge protection, labels and handling. | Inspect production-intent shipping units. | Transport damage can erase otherwise acceptable paper quality. | | Governance | Define notice period, approval owner and emergency path. | Keep a revision and affected-lot register. | ‘Equivalent’ changes become disputes when authority is unclear. | ## How to use the framework ### Material Lock grade, furnish declaration and approved alternatives. Trace declarations and production records by lot. A substitute fiber can shift performance without changing the product name. Record SKU, revision, lot, method, result and disposition. ### Performance Lock methods and limits for GSM, bulk, tensile and absorbency. Use conditioned tests on the exact production grade. Changing the method can make stable paper look different—or hide drift. Record SKU, revision, lot, method, result and disposition. ### Roll geometry Lock width, core, OD, winding and splice rules. Verify dimensions and run a controlled unwind. Converter downtime often starts at the roll interface. Record SKU, revision, lot, method, result and disposition. ### Process/site Name manufacturing and converting sites plus critical route. Require notice and qualification for transfers or material changes. A group-level certificate does not prove identical site output. Record SKU, revision, lot, method, result and disposition. ### Packing Lock wrap, edge protection, labels and handling. Inspect production-intent shipping units. Transport damage can erase otherwise acceptable paper quality. Record SKU, revision, lot, method, result and disposition. ### Governance Define notice period, approval owner and emergency path. Keep a revision and affected-lot register. ‘Equivalent’ changes become disputes when authority is unclear. Record SKU, revision, lot, method, result and disposition. The approved TAD paper supplier specification should connect sample performance to measurable limits, methods and a controlled product revision. ## Calculation or release rule A TAD paper supplier quotation is not fully comparable when substitute furnish, winding location or packaging changes can occur without reapproval. Use a change matrix with three outcomes: no notice for truly administrative changes, written notice for changes that do not alter the approved product, and prior buyer approval plus requalification for material, process, site, specification, test, or packing changes that can affect use. The contract should state who decides when classification is uncertain. ## Evidence gate before publication - Missing: Current Sansheng TAD specification revision - Missing: A signed sample-approval or golden-roll record - Missing: Sansheng's documented supplier-change notification workflow Do not invent first-hand experience, test results, or customer outcomes to fill these gaps. ## Sources and scope After sample approval, the TAD paper supplier should retain traceable records and obtain buyer authorization before implementing a defined critical change. - [Sansheng product page for the relevant product family](https://tissuepapersupplier.com/tad-paper-supplier/) — First-party product-family context; not proof that a specific draft claim or tolerance has been approved. - [Sansheng WordPress media and article record #20513](https://tissuepapersupplier.com/wp-json/wp/v2/posts/20513) — First-party content and media provenance used for this research draft; not a current QC report. - [ISO 12625-6:2016 — Determination of grammage](https://www.iso.org/standard/66472.html) — Tissue grammage method; it does not set a suitable GSM for a specific application. - [ISO 12625-4:2022 — Tensile strength, stretch and tensile energy absorption](https://www.iso.org/standard/80328.html) — Tissue tensile method; acceptance values must be agreed for the SKU. - [ISO 12625-8:2010 — Water-absorption time and capacity](https://www.iso.org/standard/53425.html) — Basket-immersion method; it does not replace a product-use trial. - [ISO 187:2022 — Standard atmosphere for conditioning and testing paper](https://www.iso.org/standard/80311.html) — Conditioning and test atmosphere; not a finished-product acceptance limit. - [ISO 2859-1:2026 — Sampling procedures for inspection by attributes](https://www.iso.org/standard/85464.html) — Lot sampling framework; the buyer still has to define defects and acceptance levels.
