When sourcing canned fruit, buyers often compare products based on can size or net weight. However, these figures do not tell the whole story.

A can labeled 1 kg does not necessarily contain 1 kg of fruit. Part of the weight comes from the packing medium, such as syrup, juice, or water. For food manufacturers, importers, distributors, and private-label buyers, understanding the difference between net weight and drained weight is essential for comparing suppliers, calculating usable fruit yield, and evaluating the real cost of a product.

So, what is the difference between net weight and drained weight? Which one should buyers focus on when comparing canned fruit specifications?

This guide explains what these two measurements mean and how they affect canned fruit purchasing decisions.

What Is Net Weight in Canned Fruit?

Net weight is the total weight of the product inside the unopened can, excluding the weight of the can and other packaging materials.

For canned fruit, net weight generally includes:

• Fruit

• Syrup

• Juice

• Water

• Other permitted packing media

For example, a canned peach product may have:

• Net weight: 1,000 g

• Drained weight: 500 g

The 1,000 g represents the total contents of the can, while the 500 g represents the fruit remaining after the packing medium has been drained according to the applicable testing method.

Therefore, net weight alone cannot tell a buyer how much fruit is actually available for use.

What Is Drained Weight?

Drained weight refers to the weight of the solid product remaining after the packing medium has been drained under a specified method.

For canned fruit, the drained portion generally represents the fruit itself, although the exact measurement method and applicable requirements can vary by product and market.

For example:

• Net weight: 1,000 g

• Drained weight: 500 g

• Packing medium: Syrup

In this example, the buyer receives 1,000 g of total contents, but approximately 500 g is the fruit portion measured as drained weight.

Net Weight vs. Drained Weight: What's the Difference?

The simplest way to understand the difference is:

The two figures answer different purchasing questions.

Why Drained Weight Matters to Canned Fruit Buyers

For retail consumers, the difference may not always be a major purchasing factor. For commercial buyers, however, drained weight can directly affect product yield and cost calculations.

Consider two suppliers offering canned peaches:

At first glance, both products appear to be the same size because both have a 1 kg net weight. But the declared drained weight is different.

For food manufacturers producing fruit desserts, bakery fillings, yogurt toppings, fruit salads, ready-to-eat products, or pastry fillings, the amount of fruit available after draining may be more relevant than the total contents of the can.

How to Calculate Drained Weight Yield

Buyers can use a simple calculation to compare the fruit portion of different products.

For example:

• Net weight = 1,000 g

• Drained weight = 600 g

600 ÷ 1,000 × 100% = 60%

The product has a 60% drained-weight ratio based on these declared figures.

However, buyers should not use the ratio alone to make a purchasing decision. Product cut, fruit size, packing medium, processing method, market regulations, and agreed specifications can all affect the final product.

Does a Higher Drained Weight Always Mean a Better Product?

Not necessarily.

A higher drained weight may mean a higher proportion of fruit relative to the packing medium, but drained weight by itself does not determine overall product quality.

Buyers should also consider:

• Fruit variety

• Fruit maturity

• Color

• Texture

• Cut and size

• Defect tolerance

• Broken pieces

• Packing medium

• Brix

• Acidity

• Ingredient declaration

• Processing specifications

• Packaging format

• Shelf life

• Food safety requirements

For example, a buyer sourcing canned peach halves may have completely different requirements from a manufacturer buying diced peaches for bakery fillings.

Therefore, drained weight should be evaluated as one part of the complete product specification.

Net Weight, Drained Weight and Can Size Are Not the Same Thing

These three terms are often confused.These three terms are often confused, especially when buyers compare different canned food formats. For more details on how can sizes, net weight, and drained weight work together, see our guide: Canned Vegetables Decoded: Can Sizes, Net Weight & Drained Weight.

For example, a buyer may request: 1 kg net weight canned peaches, 12 cans per carton.

But that specification alone is incomplete from a procurement perspective. The buyer should also ask: What is the declared drained weight per can?

Why Buyers Should Include Drained Weight in RFQs

When sending an RFQ to canned fruit suppliers, buyers should avoid specifying only “1 kg canned peaches.”

A more complete request could include: Yellow peach halves, 1 kg net weight per can, with the required drained weight, packing medium, can type, and carton configuration.

Depending on the product, buyers may also specify:

• Fruit variety

• Cut

• Grade

• Brix

• Packing medium

• Net weight

• Drained weight

• Can dimensions

• Easy-open or regular lid

• Cans per carton

• Cartons per pallet

• Cartons per container

• Private-label requirements

• Label specifications

• MOQ

• Target market

How Net and Drained Weight Affect Canned Fruit Pricing

When comparing quotations, buyers should be careful about comparing price per carton alone.

Imagine two suppliers quote the same price for a carton containing 12 cans.

The carton price may look identical, but the amount of declared drained fruit is different.

This gives the buyer another way to evaluate the quotation based on the fruit portion. For industrial applications, this comparison can be particularly useful when calculating ingredient costs.

Drained Weight Is Especially Important for Food Manufacturers

For food manufacturers, purchasing decisions are often based on cost per usable ingredient, rather than simply cost per can.

For example, a manufacturer using canned peaches in bakery products may need a specific quantity of fruit pieces per production batch.

The purchasing team therefore needs to know:

1. How much fruit is supplied per can?

2. How much fruit is supplied per carton?

3. How many cartons fit into a container?

4. What is the actual product yield?

5. What is the cost per kilogram of drained fruit?

This is why a complete canned fruit specification should include both net weight and drained weight.

What Should Canned Fruit Buyers Ask Suppliers?

Before placing an order, buyers can request a complete product specification sheet.

Net Weight vs. Drained Weight: A Practical Example

Suppose a buyer is sourcing yellow peach halves.

Required:

• Net weight: 1,000 g/can

• Packing: Heavy syrup

• 12 cans/carton

• Drained weight: supplier to specify

The buyer receives two quotations.

Although the can size and net weight are identical, the declared drained weight differs. This is why net weight should not be the only number used when comparing canned fruit suppliers.

What Should Be Included in a Canned Fruit Specification Sheet?

For B2B sourcing, a detailed specification sheet can include:

• Product name

• Fruit variety

• Fruit origin

• Crop year

• Fruit cut

• Grade

• Ingredients

• Packing medium

• Brix

• Net weight

• Drained weight

• Can size

• Can material

• Lid type

• Cans per carton

• Carton dimensions

• Shelf life

• Storage conditions

• Microbiological requirements

• Chemical/physical specifications

• Certification information

The exact specifications required will depend on the product and destination market.

Why Net Weight and Drained Weight Matter When Comparing Suppliers

When sourcing canned fruit internationally, buyers should avoid making a purchasing decision based only on price per carton.

A more meaningful comparison considers:

This approach helps importers and food manufacturers understand what they are actually buying and makes supplier quotations easier to compare.
