Paraguay Medical Device Registration 2026: Import Clearance, Certificate Numbers and Article 29 Cost Rules

1. Key takeaways

1. Article 7: the NSO of a Class I device is valid for the purpose of domestic manufacture or importation, covering both domestic and imported products — once the NSO is obtained, importation can proceed without any further shipment-by-shipment permit.
2. For imported devices of Classes II to IV, the purpose stated on the registration certificate is expressly the authorization of importation and commercialization (autorización de importación y comercialización) (Instructivo, pages 9–10).
3. Article 29: for devices without a sanitary registration or NSO, the costs of tests, studies, checks, or analyses carried out by DINAVISA on its own initiative are borne by the importer or manufacturer; for registered products, the costs are borne by the registration holder.
4. Importation of unregistered products is not a routine commercial channel; it has a lawful entry point only within exceptional frameworks such as the temporary use authorization under Res. 203/2025, which is governed by its own scope and conditions.

2. Legal basis

Read together, the two resolutions draw the boundary between the regular import channel, which runs on a valid NSO or registration certificate, and the exceptional channel under Res. 203/2025, which exists for specific situations and must not be used as a substitute for registration.

Operationally, the clearance stage is where documentary compliance becomes physical compliance. Every shipment should carry a dispatch file that pairs the certificate with the invoice, packing list, and labeling samples, so that the inspector can verify the number chain in one step. Recurrent importers benefit from standardizing this file per product family and re-verifying it whenever the label is revised, because a label change that alters the printed authorization number without a corresponding change filing creates a mismatch that no customs broker can resolve at the border. Building this discipline into the import procedure is cheaper than a single extended inspection episode.

3. Expert insights

Insight one: the type of certificate directly determines the form of the clearance documents. Class I clears on the NSO (numbers in the format DMNSO-000000-00), while Classes II to IV clear on the registration certificate number, and in both cases the number must be consistent with the number shown next to AUTORIZADO POR DINAVISA on the label. Customs declarations, labels, and certificates carrying three different numbers are the single most frequently detected defect at the point of physical verification, and each mismatch can trigger inspections, delays, and additional storage costs while the discrepancy is resolved.

Insight two: the Article 29 cost rule is a pricing signal against unregistered importation. For registered products the testing costs fall on the registration holder; for products without a certificate they fall on the importer or manufacturer. The provision makes the cost of the ship-first, register-later approach explicit — beyond the compliance risk there is a direct, uncapped expense line, because the authority’s tests, studies, checks, and analyses are charged to the party that shipped the product without papers.

Insight three: Paraguay is a landlocked country, and clearance may involve transit through neighboring countries and regional trade rules. Where goods transit through Brazilian or Argentine ports, MERCOSUR common external tariff treatment and re-export rules also come into play. The memorandum of understanding on cooperation signed between ANVISA and DINAVISA on August 20, 2026 will strengthen joint border inspections and laboratory data sharing and covers medical devices (practical estimate: a clearance-support matter, to be confirmed with the customs broker). Route planning and customs classification should therefore be settled before shipment, not at the border.

Insight four: Class I treatment under Article 7 also shapes distribution economics. Because the NSO covers domestic manufacture or importation without a further per-shipment permit, a Class I holder can plan replenishment with normal commercial flexibility, while Classes II to IV operate under a certificate whose stated purpose is importation and commercialization — meaning the holder named on the certificate is the party whose imports are covered. Distributors weighing Paraguay entry should therefore price the regulatory role they are being asked to play: holding the certificate is not a formality but the assumption of the import-authorization position, with everything that follows from it in clearance and post-market responsibility.

4. Practical recommendations

1. Cross-check the certificate number in three places before dispatch: customs declaration documents, label, and certificate must match exactly.
2. Do not schedule commercial importation without a certificate; where there is a genuine urgent need, use the channel of Res. 203/2025 and document eligibility for the exceptional framework.
3. Where transit through neighboring countries is involved, confirm tariff classification and regional rules with the customs broker in advance.
4. Write the allocation of Article 29 testing costs into the cost clauses of the distribution agreement, so the responsibility is fixed before any inspection occurs.
5. Keep a per-shipment dispatch file template covering the certificate, invoice, packing list, and label evidence, and update it whenever the certificate number, holder, or label is revised, so every consignment clears against a current and internally consistent document set.
6. Brief the local logistics team on the difference between the NSO and the registration certificate before the first shipment, so the correct document is presented for each product class at the border without improvisation.

5. Verification checklist

• □ Numbers consistent across customs documents, label, and certificate
• □ Confirmed whether the product holds an NSO or a registration certificate
• □ Importation without a certificate excluded from the commercial plan
• □ Transit and tariff classification confirmed with the customs broker (practical estimate)
• □ Party bearing testing costs written into the agreement
