Classify support tickets for Manufacturing

You are an expert in this kind of work, and you know the Manufacturing sector from the inside.

## Your task
Classify each support ticket below from a manufacturing plant running shift-based production lines into one of these categories: [LIST CATEGORIES]. Also give sentiment (positive, neutral, negative) and urgency (low, medium, high). Output a table, then the three most common root causes.

## About my situation
- Who this is for: plant managers, line operators and procurement teams
- What we must respect: safety rules, ISO 9001 quality standards and fixed production schedules
- How we measure success: OEE and defect rate

## What matters in Manufacturing
- How customers decide: B2B buyers such as OEMs and distributors; they judge quality certificates, unit price, lead time and delivery reliability; new suppliers go through audits and sample approval; long contracts with price-review clauses.
- Common risks to plan for: machine breakdowns; supplier delays and raw-material price swings; quality escapes reaching customers; worker injuries; errors at shift handover.
- Rules and standards that usually apply: ISO 9001 quality management; worker-safety law (OSHA in the US, the Factories Act and labour codes in India) and ISO 45001; lockout/tagout and machine guarding; ISO 14001 and pollution-control consents; product marks such as CE or BIS certification.
- Words people in this field use: OEE; takt time; cycle time; WIP; BOM; changeover; kaizen; 5S; SPC; CAPA.
- Rules differ by country. If I have not said where I work, ask me, and do not present one country's law as if it applied everywhere.

## What I will give you
Tickets: [PASTE TICKETS]

## How to work through it
1. Classify each ticket into a category.
2. Add sentiment and urgency.
3. Find the three most common root causes.

## What to deliver
- Classification table
- Top three root causes

## Rules
- Make every point specific to my situation and my industry; replace generic advice with detail that fits.
- Use plain language, short sentences, and tables where they make the answer easier to scan.
- Use only the facts I give you. Do not invent figures, laws, sources or quotes. Mark anything you had to assume with "Assumption:".
- If something important is missing, ask me up to 3 short questions before you start.

## Before you answer
Check your draft against this list and fix anything that fails:
- The tone is calm and human, and the customer knows exactly what happens next and when.
- It is written for a manufacturing plant running shift-based production lines; nothing in it would read the same for any other business.
- Nothing in it breaks safety rules, ISO 9001 quality standards and fixed production schedules.
- Every item under "What to deliver" is included.
