For regulatory or customs supervision purposes, some countries may require CoC based on the category of imported products.

For example, your customers or buyers may need CoC when selling your products to different markets (such as the United States, China, or European countries). Usually, without a certificate of conformity, you may face the problem of putting your product on the market.

The ability to issue a CoC allows you to promptly put your products on the market. Delays in getting your product approved may also extend the time required or even prevent your product from selling, affecting your profitability.

What Details Are Included In the Certificate of Conformance?

Generally speaking, the minimum mandatory elements that should be listed in the CoC are:

  • Product identification, including the product description and related purchase order number involved in the CoC.
  • The identity certificate of the manufacturer/importer, such as legal name, address, and contact number.
  • A list of all safety regulations/standards that the product must pass.

The manufacturer can carry out the inspection itself, or the inspection agency can inspect your products according to the given specifications.

In most cases, the Certificate of Conformance (CoC) is asked for products that are of high risk or critical. This also includes separate documentation for these products to ensure that the customers are safe to use.

For instance, an airline company purchases fan blades that they can install in the airplanes’ engines. To ensure the safety of the lives on board, these blades must be scanned through an x-ray to ensure no possible cracks or defects present there. The presence of such defects could ultimately result in potential harm to the life on board. In such cases, a CoC has to be provided to ensure the safety of those blades.

There are also instances where one needs to view a CoC for every component and a serial number to prove how safe the components are.



Why Do Some Countries’ Customs Request a Certificate of Conformance (CoC)?

When importing certain types of goods, countries will request a CoC. In this situation, CoC is usually labeled as the Certificate of Compliance or Certificate of Conformance.

This document is provided by an authorized party and is proof of the certain specification being provided in the imported goods in question. For instance, it is documented proof of the presence of certain technical specifications in a product.

This specific document is provided during customs clearance. Imported goods that do not have a CoC are either seized or simply destroyed.
