HS Code for Dialyzer: Guide to Find the Right One

A dialyzer is one of the artificial medical tools that specializes in kidney dialysis or hemodialysis. This tool has become an important device for filtering the blood waste due to kidney failure. Due to the importance of the medication, some countries that have made the pharmaceutical as their primary commodity export the dialyzer to different countries around the world. This article will give you an explanation about the dialyzer and the HS code for dialyzer, as well as how to find the right HS code for dialyzer. 

What is a dialyzer? 

A dialyzer, also commonly referred to as an artificial kidney, is one of the medications used to help people with kidney failure or renal failure. This occurred due to the kidneys’ inability to filter and remove excessive amounts of waste substances from the blood. The renal failure has five different stages, and the highest renal failure will have a severe impact on human health and lead to complications, such as high blood pressure, bone disease, anemia, nerve issues, etc. 

Due to the serious impact, the dialyzer was made as a part of the components for the hemodialysis system. The process of hemodialysis will help the body to stabilize the mineral substances and blood pressure, as well as help to control the effects or complications due to the kidney failure in the body. This treatment replicates the process of filtration in the healthy kidney. 

Dialyzer commonly has a form of a tube cartridge, and it consists of hollow fibers from artificial semipermeable membranes. These synthetic membranes are as thin as hair, and these are the crucial elements of the dialyzer for filtering the selective substances and reducing the excessive amount of some substances, and removing the waste products from the body, similar to what the kidney does. 

Not only dialyzers, but the hemodialysis process also needs the dialysis machine to pump the blood through the body. Once the blood is out of the body through the tube, the blood will pass through the dialyzer to be purified and remove some of the waste substances. Then, the purified blood will be back to the patient’s body. 

What is the HS code for dialyzer?

Because of the many people who are affected by kidney failure, the big pharmaceutical companies developed the dialyzer in order to meet the needs of the hemodialysis process. These companies from several countries produce dialyzers en masse and send dialyzer products all over the world. Therefore, actors in international trade should follow and understand the procedure of exporting or importing dialyzers, including knowing the right Harmonized Standard or HS code for dialyzers. 

The HS code for dialyzers is included in Chapter 90. This chapter covers the optical, photographic, cinematographic, measuring, checking, precision, medical, and surgical instruments and apparatus. After the chapter, the structure of the code is followed by one heading and two subheadings. This is the breakdown of the HS code for medical equipment, including for kidney treatment, which is 901890. 

• 90: Chapter for broad medical equipment. 
• 18: Heading for the appliances used in medical, surgical, dental, or veterinary sciences, including scintigraphic apparatus,
• 90: Subheading for other instruments and appliances and parts and accessories thereof. 

Meanwhile, there are no patents for the second subheading of the HS code for dialyzers or the kidney or renal dialysis instruments. The second subheading code depends on the recipient country classifications. Therefore, it needs to take a look at the classification code of dialysis instruments or equipment based on each destination country.

First question: What are the product requirements for exporting dialyzers from Mexico to the United States? 

Answer: Exporting dialyzers required some regulatory standards from the US Food and Drug Administration (FDA). This is specifically part of the Current Good Manufacturing Practice (CGMP) requirement, which the final rule was established in 22 July 2013. Compliance with the CGMP rule is crucial because dialyzers are used for therapies for kidney failure. The standards include efficacy and strict manufacturing supervision. On the other hand, the dialyzers can be subject to the hazardous material regulations if they contain some hazardous substances. The exporters must follow the UN Model Regulations, IMDG Code, and ICAO Technical Instructions, packaging, labelling, and the appropriate storage of materials for the shipping process. The export of dialyzers from Mexico also needs documentation from the national health authority in order to meet eh US standards. 

Second question: What are the steps required to obtain sanitary registration for exporting dialyzers from Mexico to the United States? 

Answer: Dilayzer is included in the medical device, which is under the supervision of Registro Sanitario in Mexico. This authority implements certain regulations, such as Ley General de Salud, Reglamento de Control Sanitario de Productos y Servicios, and Ley Aduanera, in order to export the dialyzer to the US. The steps for obtaining the sanitary registration documents in Mexico include: 1. classifying according to the specific medical devices, 2. evaluating the dialyzer products to meet the standard in Mexico, 3. submitting the formal registration to the COFEPRIS, 4. providing the required documents, 5. paying for the registrations and waiting for the approvals. Then, the FDA requires registration and a device listing label for the exported product. 

Third question: What specific documents are required in the Mexican Sanitary Registration application for dialyzer products? 

Answer: Mexican Sanitary Registration has the authority in place for exporting dialyzers from Mexico to the US. Even though there are no specific documents provided, the standard documents adhere to the TBT from the WTO. Those documents include: 1. Technical documentation, 2. Labeling and instructions for users, 3. Products declaration of conformity, 4. Certificate of Origin, 5. Regulatory Compliance Declaration. Meanwhile, there is no specification of documentation for exporting dialyzers.
