# Gloves, shawls, scarves, veils, ties, cravats and other made-up clothing accessories, knitted or crocheted; knitted or crocheted parts of garments or of clothing accessories

## 1. Scope and Applicability

This rule covers made-up gloves, shawls, scarves, veils, ties, cravats, other clothing accessories whose defining textile construction is knitted or crocheted, and knitted or crocheted garment or accessory parts sold as standalone products. The boundary ends at the accepted factory-gate product. Each data package declares its actual article, fibre composition, knit technology, purchased-fabric or on-site knitting route, finishing, joining, and packaging. Nonknitted articles and complete garments use their own category rules.

## 2. Product Category Identity

| What | Provide the declared made-up knitted or crocheted accessory or standalone part |
| How much | 1 kg accepted net product mass |
| How well | Meets the declared fibre, size, function, and acceptance specification |
| How long or cycle | One factory-gate delivery; service life is product-specific and outside this production reference |
| reference_flow_link | finished_accessory_output |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Accepted knitted or crocheted clothing accessory or garment part at factory gate |

| --- | --- | --- | --- | --- |
| `net_mass_basis` | reference product and all inventory rows | Mass | kg | Normalize per 1 kg reference flow using accepted made-up product net mass; weigh without transport packaging and separate rejects from accepted output. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |

| starting_condition_role | Foreground measured input start; connect fibre, spinning, and prior finishing through matched upstream datasets |
| product_classification_scope | Made-up accessories or standalone parts within CPC 3.0 28229; do not substitute adjacent leaves |
| recursive_input_rule | Record a purchased same-category semifinished article as a separate input with its upstream boundary disclosed; avoid double counting on-site knitting |
| upstream_dataset_requirement | Choose upstream yarn, fabric, electricity, thread, and packaging data for actual composition, geography, technology, and delivered state |
| disclosure | Disclose included and omitted routes, materials, losses, outsourced steps, disposal destinations, and input-to-factory-gate coverage |

## 6. Process Inventory Structure

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| `knitting` | On-site knitting | `conditional` | Only when yarn is knitted on site | foreground formation | per 1 kg reference flow |
| `assembly` | Cutting and joining | `required` | Record actual joining for every article; document no cutting for fully fashioned output | foreground making-up | per 1 kg reference flow |
| `release` | Acceptance and release | `required` | All accepted made-up products | reference output | per 1 kg reference flow |

The cotton route below contains concrete foreground exchanges. Other fibres, finishing agents, or trims require separate atomic flows for their real material and process after UUID review; cotton rows are not proxies for them. Interprocess transfers are recorded as paired outputs and inputs and cancel in the aggregate.
