DGTR Case: AD (OI) (17/2026)
Reference: F. No. 6/19/2026-DGTR
Countries under investigation: China PR and Malaysia
The Directorate General of Trade Remedies (DGTR) has finalised the Product Under Consideration (PUC) and Product Control Number (PCN) methodology in the ongoing anti-dumping investigation concerning imports of Dialyzers originating in or exported from China PR and Malaysia.
Through its communication dated 11 August 2026, DGTR has confirmed that the scope of the product under consideration remains unchanged from the original initiation notification, while establishing the PCN framework that will be used to compare different types of dialyzers during the investigation.
The notice also specifically excludes nine Fresenius-branded dialyzer models from the investigation and reduces the questionnaire response period from the originally prescribed 37 days to 15 days from publication of the notice on the SETU portal.
For importers, exporters, medical device distributors, hospitals, and dialysis centres dealing with dialyzers from China or Malaysia, these developments are important because the PUC and PCN framework determines how products will be identified and compared for the purposes of the ongoing anti-dumping investigation.
Key Takeaways
- DGTR has retained the original PUC scope without change.
- The investigation covers dialyzers used in haemodialysis, subject to the specified scope and exclusions.
- Nine specific Fresenius models have been expressly excluded.
- DGTR has finalised the PCN methodology based on surface area, flux, and housing material.
- The questionnaire response period has been reduced from 37 days to 15 days.
- The notice does not conclude the anti-dumping investigation or impose any anti-dumping duty.
- Interested parties may still submit relevant evidence supporting requests for additional product exclusions during the investigation.
Background: DGTR’s Anti-Dumping Investigation on Dialyzers
DGTR initiated the anti-dumping investigation through Notification No. 6/19/2026-DGTR dated 25 June 2026, concerning imports of dialyzers originating in or exported from China PR and Malaysia.
As part of the investigation process, interested parties were given an opportunity to submit comments on:
- The Product Under Consideration (PUC); and
- The proposed Product Control Number (PCN) methodology.
The comment period ended on 18 July 2026. Several interested parties submitted comments on the proposed product scope and PCN methodology, following which the domestic industry submitted responses to those comments. DGTR subsequently considered the submissions and evidence available on record before finalising the framework.
What is the Product Under Consideration (PUC)?
The PUC in the investigation is Dialyzers.
DGTR describes a dialyzer as a disposable medical device used in haemodialysis treatment. It functions as an artificial kidney and performs the critical function of removing waste substances, excess fluid, and toxins from a patient’s blood.
The device operates through diffusion and filtration using a semi-permeable hollow fibre membrane, allowing impurities to pass into the dialysate while retaining blood cells and essential components.
Dialyzers are available in different membrane surface areas and are also classified according to their membrane flux.
PUC Scope Retained Without Change
One of the key outcomes of the DGTR notice is that the Authority has retained the PUC scope as originally notified.
After considering comments from interested parties, responses from the domestic industry, and the evidence available on record, DGTR decided to adopt the same product scope contained in the original initiation notification without changes.
This means the clarification does not expand or narrow the general definition of dialyzers covered by the investigation.
Nine Fresenius Dialyzer Models Excluded
DGTR has expressly excluded certain dialyzers manufactured and exported by Fresenius from the investigation.
The excluded models are:
- F6 HPS
- F7 HPS
- FX5
- FX8
- FX10
- FX60
- FX80
- HF60
- HF80
The exclusion is specifically tied to the named Fresenius models identified in the DGTR notice.
Businesses dealing in these specific models should nevertheless retain appropriate product and commercial documentation demonstrating that the imported products correspond to the excluded models.
DGTR Finalises the PCN Methodology
The Product Control Number (PCN) methodology is particularly important in an anti-dumping investigation because it establishes a structured basis for comparing products with different characteristics.
DGTR has finalised the PCN methodology using three parameters:
1. Surface Area
Dialyzers are classified according to membrane surface area:
- 1.3 m² and below — Code X
- Above 1.3 m² and below 1.8 m² — Code Y
- 1.8 m² and above — Code Z
2. Flux
Dialyzers are categorised as:
- High flux — Code H
- Other (Low and Mid flux) — Code M
3. Housing Material
The methodology distinguishes between:
- Polycarbonate — Code PC
- Polypropylene — Code PP
These parameters will be used to establish comparable product categories for the investigation.
Why Does the PCN Methodology Matter?
The PUC defines which products fall within the investigation, while the PCN methodology determines how products are categorised and compared.
This makes the PUC/PCN stage particularly significant for:
- Exporters
- Importers
- Domestic manufacturers
- Medical device distributors
- Other interested parties participating in the investigation
The finalised PCN structure will influence how different dialyzer products are matched for the purposes of the dumping and injury analysis.
For businesses, accurate product mapping against the PCN parameters is therefore important when preparing submissions and questionnaire responses.
Questionnaire Deadline Reduced to 15 Days
Another significant development is the reduction in the timeline for submitting questionnaire responses.
The original deadline was 37 days from the date of intimation.
Following the PUC/PCN exercise, DGTR has directed interested parties to submit their questionnaire responses within 15 days from publication of the notice on the SETU portal.
This represents a substantial reduction in the available response period.
Companies participating in the investigation should therefore review their product data, transaction information, cost records, and supporting documentation immediately rather than waiting until the end of the response period.
What Does This Mean for Importers and Exporters?
The latest DGTR notice has several practical implications.
Importers of Dialyzers from China and Malaysia
Importers should determine how their products fit within the final PCN methodology and monitor the investigation closely.
Any eventual trade remedy could have implications for landed costs and procurement strategies.
Medical Device Distributors
Distributors should review the country of origin and product specifications of dialyzers sourced through their supply chains and identify whether products fall within the investigation.
Hospitals and Dialysis Centres
Hospitals and dialysis centres sourcing dialyzers from China or Malaysia should monitor the investigation as a potential future cost factor for an essential medical consumable.
Fresenius Product Importers
Importers handling the nine specifically named Fresenius models should verify that their products correspond to the models expressly excluded from the current investigation.
Does This Notice Mean Anti-Dumping Duty Has Been Imposed?
No.
This is an important distinction.
The DGTR notice only finalises the PUC and PCN methodology for the ongoing anti-dumping investigation. It does not represent a final finding of dumping, injury, or a recommendation to impose anti-dumping duty.
Therefore, businesses should not treat this notification as an operative anti-dumping duty measure.
Any eventual recommendation or imposition of anti-dumping measures would depend on the subsequent stages and findings of the investigation.
Can Additional Product Exclusions Still Be Requested?
Yes.
DGTR has specifically clarified that the notice is limited to clarifying the scope of the PUC and does not prevent interested parties from providing additional relevant information and evidence to support requests for exclusion of particular products.
The Authority will consider relevant information and evidence submitted during the investigation when determining the scope of any measures that may ultimately be recommended.
This is particularly relevant for businesses whose products have characteristics that may distinguish them from the products manufactured by the domestic industry.
Recommended Actions for Businesses
Businesses affected by the investigation should consider the following steps:
1. Map Products Against the PCN Grid
Review every relevant dialyzer SKU against:
- Surface area
- Flux
- Housing material
2. Verify Product Exclusions
If importing Fresenius products, confirm whether the specific model corresponds to one of the nine expressly excluded models.
3. Review Questionnaire Requirements
Interested parties should assess the shortened 15-day response period and begin compiling the required information immediately.
4. Preserve Supporting Evidence
Maintain technical specifications, invoices, product catalogues, import records, and other documentation supporting product classification or exclusion requests.
5. Monitor the Investigation
The PUC/PCN methodology is an important procedural milestone, but the anti-dumping investigation itself is continuing.
