Not all packaging is just packaging. In many situations, the container, case, or presentation of a product affects how it must be classified under the Harmonized Tariff Schedule. General Rule of Interpretation 5 provides the legal structure for determining when packaging follows the classification of the product and when it must be treated separately. Understanding these rules helps avoid misclassification, overpayment of duties, and inconsistencies across large catalogs.

GRI 5 is divided into two parts, each addressing a different type of packaging: specialized cases and ordinary packing materials. These distinctions matter because some containers have long term use or intrinsic value, while others are simply there to protect the product during shipment.

GRI 5(a): Specially Shaped or Fitted Containers

GRI 5(a) covers containers that are:

• Specially shaped or fitted for a specific product
• Designed for long term use
• Presented with the product at import
• Suitable for reuse with that product

Examples include:

• Instrument cases
• Camera cases
• Tool cases molded for a specific tool
• Protective cases for scientific or technical equipment

Under GRI 5(a), these containers are classified with the goods they are designed to hold. This means the case does not receive a separate classification when:

• It is imported with the product
• It is clearly intended to house that product for repeated use
• It matches the shape or outline of the product
• It contributes to the identity or normal commercial presentation of the good

If the case meets all these conditions, it follows the same HTS code as the product itself.

When GRI 5(a) Does Not Apply

A container does not follow the product when:

• It is not specially fitted
• It is not intended for long term use
• It is suitable for general use with other products
• It is presented separately from the product

In these cases, the container must be classified independently according to its own characteristics.

GRI 5(b): Ordinary Packing Materials and Containers

GRI 5(b) applies to standard packaging used for shipping, transport, or basic retail presentation. These materials and containers usually follow the classification of the goods they contain. The rationale is straightforward: ordinary packaging does not define the commercial identity of the product.

Examples include:

• Cardboard boxes
• Plastic bags
• Blister packs
• Foam inserts
• Standard retail packaging
• Disposable bottles or jars that are not specialized

These materials are not classified separately unless they are clearly suitable for repetitive use or have independent commercial value apart from the product.

Exceptions for GRI 5(b)

Ordinary packing materials are classified separately only when:

• They are designed for repeated use (such as industrial plastic crates)
• The tariff requires separate classification for the packaging
• The packaging has substantial commercial value exceeding normal expectations

These exceptions are uncommon but important in industrial or bulk shipping contexts.

Why GRI 5 Matters for Importers

GRI 5 ensures that classification remains consistent and aligned with commercial reality. Without it, similar goods could be classified differently depending on how they were packaged, creating discrepancies in duty rates and compliance workflows. GRI 5 also prevents unnecessary separation of items that belong together and provides structure for cases where packaging has independent value.

Correct application of GRI 5 helps teams:

• Distinguish between specialized and ordinary packaging
• Avoid misclassifying reusable containers
• Maintain consistent treatment across product lines
• Support audit ready documentation for packaging scenarios

Documentation Needed to Apply GRI 5

To classify packaging accurately, teams should gather:

• Clear product descriptions
• Details about the container’s material and purpose
• Whether the container is fitted or molded
• Whether it is intended for repeated use
• Whether it is imported together with the product
• Any commercial information on how the goods are normally sold

This information allows the classifier to review the packaging under GRI 5(a) or 5(b) and determine whether it should follow the product or be treated as its own item.

The Bottom Line

GRI 5 provides a structured way to classify packaging, cases, and containers based on their function and relationship to the goods they accompany. By distinguishing between specialized fitted cases and ordinary packing materials, the rule ensures consistent and legally sound HTS decisions. Mastering GRI 5 is essential for companies handling technical equipment, instruments, tool sets, retail goods, and products with protective or molded cases.
