Receiving, Storage, and Distribution

Receiving, Storage, and Distribution

Module Introduction

This chapter covers all activities related to the physical management of parts and merchandise in an automotive, industrial, or heavy vehicle parts distribution facility. For the Red Seal exam, you must master not only the basic procedures, but also safety standards, space calculations, inventory rotation principles, and applicable federal regulatory requirements. This module represents a significant portion of the exam, typically between 15% and 20% of the questions.

Receiving Goods

Role and Responsibilities of the Parts Technician

The parts technician assumes the legal and professional responsibility to verify that every item received matches the order exactly. This function requires meticulous attention to detail, as a receiving error can lead to financial losses, repair delays, and safety risks for end users.

Your role includes:

Standard Receiving Procedure

The receiving procedure consists of seven distinct steps. Each step must be performed in order to ensure the integrity of the process.

Step 1 — Preparation: Before the carrier arrives, prepare the receiving area. Ensure the space is clear, that material handling equipment (pallet jack, hand truck, forklift) is available, and that staff are informed.

Step 2 — Receiving the Carrier: Greet the delivery driver and request the bill of lading. This official document describes the cargo, the number of packages, and the transport conditions. Never sign a bill of lading before inspecting the goods.

Step 3 — Physical Inspection: Count the packages and compare the number against the bill of lading. Inspect each package for signs of damage: dents, tears, moisture stains, loose strapping bands. If a package is damaged, note it on the bill of lading before signing, in the presence of the driver.

Step 4 — Conformity Verification: Open the packages and compare each item against the purchase order. Verify:

Step 5 — Documentation: Complete the receiving report and enter the data into the IMS. Note any anomalies: missing quantity, damaged item, incorrect part number, unordered item.

Step 6 — Labeling and Identification: Affix the receiving label to each item or lot. The label must include the receiving date, order number, part number, and quantity.

Step 7 — Routing: Route the parts to their designated storage location or to the immediate availability area if the part is intended for a pending customer order.

Managing Discrepancies and Claims

When a discrepancy is detected, you have a maximum of 24 hours to report the problem to the supplier, unless otherwise stated in the terms of sale. Claims for transport damage must be addressed to the carrier within 48 hours of receipt, in accordance with standard industry practices.

Document each discrepancy with photographs, serial or lot numbers, and retain all original packaging for subsequent inspections. Claim resolution can take 7 to 30 days depending on the complexity of the case.

Parts Storage

Fundamental Storage Principles

Effective storage is based on three fundamental principles: accessibility, protection, and traceability. Each part must be quickly accessible, protected against damage and deterioration, and traceable at all times in the system.

Accessibility: Fast-moving parts (Class A) should be placed in the most accessible areas, at chest or waist height. Slow-moving parts (Class C) can be placed on upper or lower shelves.

Protection: Certain parts require specific storage conditions:

Traceability: Each part must be uniquely identified in the system. The barcode or QR code on the label must be scannable and linked to the physical location in the database.

Classification and Location Methods

The choice of classification method depends on the volume of parts, the diversity of references, and the frequency of turnover. The main methods are:

Storage Space Calculation

To determine the required space, use the following formula:

Required Space (m³) = (Annual Quantity × Unit Volume × Safety Factor) ÷ Turnover Rate

The safety factor ranges from 1.2 to 1.5 depending on demand variability. The turnover rate is the number of times inventory is renewed annually.

Practical Example: A dealership sells 240 oil filters per year. Each filter measures 0.1 m × 0.1 m × 0.15 m (volume = 0.0015 m³). The turnover rate is 6. The safety factor is 1.3.

Required space = (240 × 0.0015 × 1.3) ÷ 6 = 0.468 ÷ 6 = 0.078 m³

This calculation helps size shelving and storage bins.

ABC Analysis and Inventory Classification

ABC analysis, based on the Pareto principle (80/20), classifies parts according to their annual monetary value:

Class A: 10 to 20% of references represent 70 to 80% of total value. These parts require rigorous control, frequent inventory counts, and precise replenishment.

Class B: 20 to 30% of references represent 15 to 20% of total value. Periodic control, monthly or quarterly inventory counts.

Class C: 50 to 70% of references represent 5 to 10% of total value. Simplified control, annual inventory counts.

This classification guides decisions on location, safety stock levels, and counting frequency.

Distribution and Shipping

Order Picking Process

Order picking is the most labour-intensive activity in a parts facility. An efficient process reduces errors and increases productivity.

Picking Methods:

Final Verification: Before shipping, an independent verification must be performed. Compare the prepared order against the delivery slip, item by item. Verify the part number, quantity, and condition of each part.

Packaging and Parts Protection

Packaging must protect the part against shock, vibration, moisture, and corrosion during transport. Common packaging materials include:

Rule of Thumb: A part must be able to survive a one-metre drop without sustaining damage. If the packaging does not guarantee this protection, reinforce it.

Shipping Documentation

Shipping documents must be complete and accurate. The essential documents include:

Delivery Slip: Detailed list of shipped items, with part numbers, quantities, and descriptions. It serves as proof of delivery and must be signed by the recipient.

Bill of Lading: Transport contract between the shipper and the carrier. It describes the cargo, route, and transport conditions.

Invoice: Commercial document indicating prices, taxes, and payment terms.

Certificate of Origin: Document attesting to the country of origin of the goods, required for international trade.

Dangerous Goods Declaration: Required for the transport of dangerous goods, in accordance with Transport Canada's Transportation of Dangerous Goods Regulations (TDGR).

Returns Management

Return Policies and Procedures

Parts returns can come from internal customers (repair shop) or external customers (end users). Each facility must have a clear return policy, compliant with industry standards.

General Return Conditions:

Non-Returnable Parts: Certain parts cannot be returned for safety or hygiene reasons:

Returns to the Supplier

When a part is returned to the supplier, the technician must:

Safety Standards and Regulations

Canadian Electrical Code, Part I

The Canadian Electrical Code, Part I (CE Code) governs the installation and use of electrical equipment in workplaces. For the parts technician, the relevant rules concern:

CSA B149.1 — Natural Gas and Propane Code

CSA B149.1 applies to natural gas and propane installations. In a parts facility, this code is relevant if the facility has gas-powered equipment (heating, propane forklifts). Requirements include:

Transportation of Dangerous Goods Regulations (TDGR)

The TDGR from Transport Canada governs the transport of dangerous goods by road, rail, air, and sea. Automotive parts classified as dangerous goods include:

The parts technician must know the documentation, labeling, and training requirements for these goods.

Material Handling and Lifting Standards

Manual handling is governed by provincial occupational health and safety regulations, but the general principles are common. The maximum recommended load for manual lifting is 23 kg according to ergonomic guidelines. Beyond this load, use mechanical handling equipment.

Common Material Handling Equipment:

Inventory Management and Stock Control

Inventory Valuation Methods

The inventory valuation method directly affects financial statements and replenishment decisions. The main methods are:

Weighted Average Cost (WAC): The cost of each unit is calculated by dividing the total cost of goods available by the total number of units available. This method smooths out price variations.

First In, First Out (FIFO): The oldest parts are sold first. This method is appropriate for perishable parts or those subject to obsolescence.

Last In, First Out (LIFO): The most recent parts are sold first. This method is less commonly used in the parts industry.

Inventory Turnover and Turnover Rate

The inventory turnover rate measures the efficiency of inventory management. It is calculated as follows:

Turnover Rate = Cost of Goods Sold ÷ Average Inventory Value

A high turnover rate indicates efficient management, but a rate that is too high can mean frequent stockouts. A rate that is too low indicates overstocking and excessive holding costs.

Example: A company has a cost of goods sold of $500,000 and an average inventory value of $125,000.

Turnover rate = 500,000 ÷ 125,000 = 4 turns per year

This means inventory is renewed four times per year, representing an average of 91 days of stock (365 ÷ 4).

Physical Inventory and Cycle Counting

Physical inventory is a complete count of all items in stock, typically performed once or twice per year. It requires stopping operations and mobilizes significant resources.

Cycle counting is a rotating count of a portion of items at regular intervals. Class A items are counted more frequently (monthly), Class B items quarterly, and Class C items annually.

Cycle Counting Procedure:

Acceptable Variance Tolerances

Inventory variances are inevitable, but they must be controlled. Typical tolerances are:

A variance exceeding these tolerances requires a thorough investigation.

Inventory Management Systems

Types of Systems

Manual System: Use of paper stock cards or registers. This system is still used in very small businesses, but it is prone to errors and does not allow real-time tracking.

Computerized System: Use of inventory management software (IMS) with barcodes or QR codes. This system allows real-time tracking, replenishment alerts, and detailed reports.

Point of Sale (POS) System: Integrated with the inventory management system, it records each sale and automatically updates stock levels.

Enterprise Resource Planning (ERP) System: Integrated system that manages all aspects of the business, including inventory, purchasing, sales, and accounting.

Reorder Point and Safety Stock

The reorder point is the stock level that triggers a replenishment order. It is calculated as follows:

Reorder Point = (Average Daily Demand × Lead Time) + Safety Stock

Safety stock protects against demand variations and delivery delays. It is calculated with the formula:

Safety Stock = Z × σ × √(Lead Time)

Where Z is the service factor (1.28 for 90%, 1.65 for 95%, 2.33 for 99%), σ is the standard deviation of daily demand, and lead time is expressed in days.

Example: The average daily demand for a part is 5 units, with a standard deviation of 2 units. The lead time is 7 days. The desired service level is 95% (Z = 1.65).

Safety stock = 1.65 × 2 × √7 = 1.65 × 2 × 2.65 = 8.73 ≈ 9 units

Reorder point = (5 × 7) + 9 = 35 + 9 = 44 units

When stock reaches 44 units, a replenishment order must be placed.

Economic Order Quantity (EOQ)

The economic order quantity minimizes the total inventory management cost, which includes ordering cost and holding cost. The formula is:

EOQ = √(2 × D × S ÷ H)

Where D is annual demand, S is the cost of placing an order, and H is the annual holding cost per unit.

Example: The annual demand for a part is 1,200 units. The cost of placing an order is $25. The annual holding cost per unit is $3.

EOQ = √(2 × 1,200 × 25 ÷ 3) = √(60,000 ÷ 3) = √20,000 = 141.4 ≈ 141 units

The optimal quantity to order is 141 units per order.

Pitfalls to Avoid

Summary

Receiving, storage, and distribution of parts constitute an integrated process that requires rigorous attention at every step. Key points to remember:

To succeed on the Red Seal exam, practice reorder point, safety stock, and EOQ calculations until they become automatic. Familiarize yourself with the requirements of Canadian standards and standard industry procedures. Accuracy and rigour are the essential qualities of the professional parts technician.
