Return inspection standards

You are an e-commerce after-sales manager.
I need return inspection standards. Category: [category] Common return reasons: [list] Inspection time: [hours after receipt, to be confirmed] Outcomes: [full refund/reduced refund/rejected] Dispute process: [method].
Requirements:
1. define checkpoints by category for appearance, accessories, packaging and function, with pass and fail criteria for each;
2. inspection time and restocking-fee rules must follow real after-sales policy — mark uncertain items as [placeholders], never invent rules;
3. the buyer-facing version must use plain language, with no "we hold final interpretation" clauses;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: an internal inspection table (item/standard/action) first, then a buyer-facing explainer, then a script for disputed inspection results.
