Leather is one of the oldest and most versatile materials used to manufacture jackets, bags, wallets, belts, footwear, furniture, and countless other products. While the finished product appears refined and durable, it begins as a raw animal hide that must pass through multiple processing stages before becoming usable leather.

Every step in the manufacturing process plays an important role in determining the leather’s strength, flexibility, appearance, and longevity. From preserving the raw hide to tanning, dyeing, and finishing, each stage contributes to the quality of the final product.

Whether you’re an importer, brand owner, sourcing agent, or simply interested in how leather products are made, understanding the manufacturing process can help you make more informed purchasing and sourcing decisions.

This guide explains how leather is made, step by step, from raw hide to finished leather ready for manufacturing.

What Is Leather?

Leather is a natural material produced by processing animal hides through a series of manufacturing steps designed to improve durability, flexibility, and resistance to decomposition.

The most common hides used in leather production include:

Cowhide
Buffalo hide
Goat skin
Sheep skin
Calfskin

Raw animal hides cannot be used directly because they naturally decompose over time. Through tanning and other manufacturing processes, the hide becomes stable, durable, and suitable for producing high-quality leather goods.

If you’re unfamiliar with the different leather materials available, our Types of Leather Explained guide provides a detailed overview of the most common leather types used in manufacturing.

Step 1: Raw Hide Collection

Leather production begins immediately after the animal hide is removed.

The quality of the finished leather largely depends on the condition of the raw hide. Deep scars, insect bites, branding marks, and improper handling can affect the final appearance and performance of the leather.

Manufacturers inspect hides before processing to identify defects and determine the most suitable applications for each hide.

During this stage, they also sort hides based on factors such as:

Size
Thickness
Surface quality
Species
Intended product use

Higher-quality hides are typically reserved for premium leather products, while lower-grade hides may be used for products with corrected finishes.

Step 2: Curing and Preservation

Fresh hides begin to deteriorate within hours if they are not properly preserved.

To prevent bacterial growth and decomposition, manufacturers cure the hides before transporting them to a tannery.

Common preservation methods include:

Salt Curing

Large quantities of salt are applied to remove moisture and slow bacterial activity. This is the most widely used preservation method.

Refrigeration

Some manufacturers temporarily store hides under controlled temperatures before processing.

Air Drying

In certain regions, hides are dried under controlled conditions to preserve them before tanning.

Proper curing helps maintain hide quality during transportation and storage.

Step 3: Soaking and Cleaning

Once the hides arrive at the tannery, they are thoroughly soaked in water.

This process restores moisture lost during curing while removing:

Dirt
Blood
Salt
Dust
Surface contaminants

Cleaning ensures that the hide is properly prepared for the next manufacturing stages and allows chemicals used later in the process to penetrate more evenly.

Step 4: Liming and Hair Removal

After cleaning, the hides are treated with a lime solution.

This stage loosens hair, removes unwanted proteins, and opens the fiber structure, making the hide easier to process.

Machines then remove the hair and remaining surface tissue.

Liming also prepares the leather for tanning by improving chemical penetration and creating a cleaner working surface.

Without this step, producing high-quality leather would be extremely difficult.

Step 5: Fleshing and Splitting

After hair removal, the underside of the hide still contains excess fat and connective tissue.

During fleshing, specialized machines remove these unwanted materials, leaving a clean and even hide.

The hide is then split into different layers depending on its intended use.

The upper grain layer is generally used for premium leather products, while lower layers are processed for other leather applications.

If you’d like to understand how these layers affect leather quality, read our guide on Understanding Leather Grades.

Step 6: Deliming and Bating

Following liming, the hide undergoes deliming to reduce its alkalinity.

Enzymes are then introduced during the bathing process to soften the fibers and improve flexibility.

Although this stage receives less attention than tanning, it has a significant impact on the finished leather’s softness, texture, and workability.

Proper deliming and bating help manufacturers produce leather that feels comfortable while maintaining structural strength.

Step 7: Pickling

Before tanning begins, the hide is treated with acids and salts in a process known as pickling.

The primary purpose of pickling is to lower the pH level of the hide, creating the ideal conditions for tanning agents to penetrate evenly.

Skipping or poorly performing this stage can reduce tanning effectiveness and negatively affect the leather’s durability.

Step 8: Tanning

Tanning is the most important stage in leather manufacturing.

Without tanning, animal hides would eventually decay.

The tanning process stabilizes the collagen fibers inside the hide, transforming it into durable leather that resists moisture, bacteria, and decomposition.

The two most common tanning methods are chrome tanning and vegetable tanning.

Chrome Tanning

Chrome tanning uses chromium salts to produce soft, flexible leather in a relatively short period.

This method is widely used for manufacturing:

Leather jackets
Handbags
Shoes
Upholstery
Fashion accessories

Chrome tanned leather is known for its consistent appearance, flexibility, and efficient production.

Vegetable Tanning

Vegetable tanning uses natural tannins extracted from tree bark and other plant materials.

Although the process takes much longer, it produces leather with a firm structure and a rich natural appearance.

Vegetable tanned leather is commonly used for:

Belts
Wallets
Saddlery
Watch straps
Luxury leather goods

Step 9: Dyeing and Fatliquoring

Once tanning is complete, manufacturers add color and improve the leather’s flexibility.

During dyeing, pigments penetrate the leather to achieve the desired shade.

After dyeing, oils and lubricants are added through a process called fatliquoring.

This step helps:

Maintain softness
Improve flexibility
Prevent cracking
Enhance durability

Proper fatliquoring ensures the leather remains comfortable and performs well throughout its lifespan.

Step 10: Drying and Conditioning

After dyeing and fatliquoring, the leather still contains moisture that must be carefully removed. Controlled drying helps maintain the leather’s shape, texture, and strength while preventing shrinkage or distortion.

Manufacturers use different drying techniques depending on the type of leather and the intended application.

Common drying methods include:

Air drying
Vacuum drying
Toggle drying
Hang drying

Once the leather reaches the desired moisture level, it is conditioned with oils and finishing treatments to improve softness and flexibility.

Proper drying and conditioning ensure the leather remains comfortable to work with and performs well in finished products.

Step 11: Finishing

The finishing stage gives leather its final appearance and improves its performance.

Depending on the product requirements, manufacturers may apply various finishing techniques to achieve a specific look or feel.

Common finishing processes include:

Buffing

The surface is lightly polished to create a smoother finish and remove minor imperfections.

Embossing

A patterned texture is pressed onto the leather to create decorative designs or imitate exotic leather textures.

Protective Coating

A protective finish improves stain resistance, scratch resistance, and overall durability.

Surface Coloring

Additional pigments may be applied to achieve consistent color across large production runs.

The finishing process allows manufacturers to produce leather with different textures, colors, and performance characteristics for various industries.

Step 12: Quality Inspection

Before leather leaves the tannery, it undergoes a final quality inspection.

This stage ensures the material meets the required standards before being supplied to manufacturers.

Inspectors typically examine:

Surface quality
Grain consistency
Leather thickness
Color uniformity
Softness and flexibility
Visible defects
Overall finish

Leather that passes inspection is graded and prepared for shipment.

Quality inspection helps manufacturers reduce production issues and maintain consistency across large orders.

From Leather to Finished Products

After inspection, the finished leather is supplied to manufacturers who transform it into a wide range of consumer and industrial products.

Common applications include:

Leather jackets
Handbags
Wallets
Belts
Shoes
Boots
Gloves
Travel bags
Furniture upholstery
Safety equipment

Each product requires different leather characteristics. For example, jackets often require soft and flexible leather, while belts benefit from firmer leather with greater structural strength.

Understanding these differences helps buyers select the right leather for their products.
