A “certificate of registration as importer” is usually not a single universal U.S. federal document. In practice, people often use that phrase to mean one of three things: an importer identification number for CBP entry filings, the question of who is the importer of record, or a commodity-specific permit, licence, or certification required by another government agency. The right answer depends on what you are importing, not just on the fact that you are bringing goods into the United States.
If you are trying to start importing into the U.S., the most useful first step is not to search for one all-purpose certificate. It is to identify the product, check whether another agency regulates it, and then confirm what importer number or entry documentation you need before the shipment is filed.
What Is a Certificate of Registration as Importer in the U.S.?
In U.S. trade practice, that phrase is usually used loosely. It does not mean there is one standard federal “importer licence” that every importer must obtain for every product. U.S. Customs and Border Protection does not require a general import licence or permit for all imports, but other agencies may require permits, licences, or certifications depending on the commodity, as explained in this new importer guidance from Shapiro.
So if someone asks for a “certificate of registration as importer”, they may actually be asking for one of the following:
- an importer number used in CBP entry filings;
- proof that you are the importer of record;
- a commodity-specific licence, permit, or certification; or
- a document required by another country, such as an import certificate or controlled-goods authorisation.
That distinction matters because these are not interchangeable documents. A general importer registration concept is not the same as a certificate of origin, and it is not the same as FDA-related import certification or other agency approvals.
Do You Need an Import Licence or Importer Registration in the U.S.?
For most routine imports, the short answer is: not a single universal federal import licence. CBP’s role is to process entry and enforce customs requirements, while other agencies may impose their own rules for specific goods. The U.S. government’s trade guidance also notes that import licences are the importer’s responsibility and can vary depending on destination and product, as set out in Trade.gov’s special documents guidance.
For beginners, the practical setup usually looks like this:
- Identify the product and its tariff classification.
- Check whether CBP alone is involved or whether another agency also regulates the goods.
- Make sure you have the correct importer identifier for entry filings.
- Obtain any product-specific permits, certificates, or registrations before the shipment moves.
In other words, U.S. import compliance is usually a combination of customs entry requirements plus commodity-specific rules, rather than one universal licence covering everything.
What importer number is used in CBP filings?
CBP entry forms ask for an importer number. According to the importer guidance cited above, that number is typically the importer’s IRS business registration number. If the business is not registered with the IRS or the importer does not have a business, a Social Security number may be used. Alternatively, a CBP-assigned number can be requested by submitting CBP Form 5106.
This is often what people are really asking for when they search for an “importer certificate” or “registration as importer” in the U.S. The practical issue is not a paper certificate in the abstract; it is whether you have the right identifier to make entry.

How Do You Know If You Are the Importer of Record?
The importer of record is the party responsible for clearing the goods through CBP and making entry. In practice, that is the legal entity that takes responsibility for the shipment during the import process. A customs and importation overview from Crowell explains that the importer of record must file an entry package, and CBP’s ACE FAQs also make clear that the importer of record controls the authorised users for the ACE Portal and is responsible for responses to CBP requests.
A useful way to tell whether you are the importer of record is to ask these questions:
- Are you the party filing or responsible for the entry documentation?
- Are you the party CBP will contact for requests, forms, or responses?
- Are you responsible for the goods’ classification, valuation, and customs compliance?
- Are you maintaining the required import records?
If the answer is yes to those questions, you are likely acting as the importer of record, even if you were not thinking about it in those exact words. This is why it is important not to confuse importer-of-record status with a general importer registration document.
The importer of record role is covered in more depth in our article on importer of record responsibilities.
What are the importer of record responsibilities?
The source material points to several core responsibilities. The importer of record must exercise reasonable care, classify and value the merchandise correctly, provide information needed for CBP to assess duties and determine compliance, respond to CBP requests, and keep import records for five years. Those are not optional administrative details; they are central to making a lawful entry.
In practical terms, that means the importer of record should be ready to:
- provide accurate entry data;
- support the declared customs value;
- support the HS or HTS classification;
- provide any supporting documentation requested by CBP; and
- retain records for the required period.
This is one of the biggest reasons why “registration as importer” is a misleading phrase. The real issue is often not whether you have a certificate, but whether you are taking on the customs responsibility that comes with importer-of-record status.
When Do You Need FDA Registration or Another Agency Permit?
Some imports are regulated by agencies other than CBP. That is why the answer to “Does an importer need FDA registration?” is “sometimes, depending on the product”, not “always”. The FDA’s import certification page describes import certification as a targeted tool used to address specific food safety problems associated with imported foods. That is not the same thing as a universal import licence for all goods. You can read the FDA’s explanation on import certification.
Other agencies may also apply, depending on the commodity. Trade.gov notes that importers may need additional documentation or permits for different products, and the SBA highlights that trade-related permits and certificates can arise under agencies such as the FDA, USDA, CPSC, and Fish and Wildlife Service. The practical point is simple: product category matters.
Which products are more likely to need extra agency paperwork?
Examples commonly include food, drugs, cosmetics, medical devices, consumer products, wildlife-related goods, and certain restricted or controlled items. That does not mean every shipment in those categories needs the same document, but it does mean the importer must check the specific agency rules before shipping.
For beginners, the safest approach is to treat agency-specific registration or certification as separate from CBP entry setup. A product may require FDA-related compliance, but that alone does not answer who the importer of record is or whether you have the correct CBP importer number.
Import Certificate, Import Licence, or Certificate of Origin: What’s the Difference?
These terms are often mixed up, but they are not the same.
| Term | What it usually means | Why it is different |
|---|---|---|
| Import licence | Permission or approval tied to importing a particular product or into a particular country | There is no universal CBP import licence for all U.S. imports |
| Import certificate | In some jurisdictions, a document authorising or confirming entry of certain goods | It is not the same as U.S. importer registration |
| Importer registration | An identifier or registration step used for customs entry | May involve an IRS number, SSN, or CBP-assigned number |
| Certificate of origin | Proof of where goods were produced, manufactured, or processed | It proves origin, not importer status |
A certificate of origin is an important customs document, but it answers a different question: where the goods were made or processed. It does not prove that you are registered as an importer. If you need a deeper explanation of that document, see our article on commercial goods and customs documents, which also helps clarify how customs paperwork differs by purpose.
Some search results use “import certificate” in the context of foreign-country requirements or controlled goods. That is another reason to be careful: a document used in one country or under one regime may not be the right term for U.S. import compliance.
What Does It Cost to Get Set Up as an Importer?
There is no reliable evidence for one universal “U.S. import licence cost”, because CBP does not require a general import licence for all goods. So it would be misleading to quote a single nationwide fee.
What you may face instead are different categories of cost:
- fees for agency-specific permits or certifications, where applicable;
- costs associated with a customs broker or compliance support;
- customs bond costs, if a bond is required;
- documentation or filing costs; and
- product-testing or registration costs for regulated commodities.
For example, if you are trying to understand how broader import readiness costs can build up, our guide on customs bond amount is a useful next read. Import setup is often less about one licence fee and more about the full compliance package around the shipment.
What Should a Beginner Do Next?
If you are new to importing, use this sequence rather than chasing a vague “certificate of registration as importer”:
- Identify the product. Know exactly what you are importing and how it is classified.
- Check agency rules. Decide whether FDA, USDA, CPSC, or another agency regulates the product.
- Confirm importer-of-record status. Make sure you know who will be legally responsible for the entry.
- Arrange your importer identifier. Use an IRS business registration number, SSN where applicable, or request a CBP-assigned number through Form 5106.
- Prepare the required permits or certificates. Get commodity-specific approvals before the shipment is filed.
- Keep records. Maintain documentation so you can respond to CBP and support your entry.
If you want a practical companion to this process, our article on customs POA explains another common part of the entry and authorisation process, especially when a broker or agent is handling customs paperwork on your behalf.
Key Takeaway
In U.S. practice, a “certificate of registration as importer” usually does not mean one universal government document. It usually points to importer identification, importer-of-record responsibility, or a commodity-specific permit or certification. CBP does not require a general import licence for every shipment, but some products do trigger additional agency rules. If you start by identifying the product, confirming who the importer of record is, and checking whether another agency applies, you will usually get to the correct requirement much faster than searching for one all-purpose certificate.
