Wound Dressing Classification in Korea: Start with Purpose, Contact and Claims

Begin with which wound the product is used on, how it acts and what it claims to achieve. The same material can raise different classification and evidence questions when that description changes.

1. Write one clear intended-use statement

Do not collapse wound management, healing promotion, protection, absorption and scar management into one meaning. Establish what the product is designed to do, its wound types and stages, and its limitations. Directly translating a broad promotional statement can unintentionally expand the proposed scope.

MFDS's integrated dressing guidance addresses definitions, classification, submission evidence and clinical evidence considerations. Compare each product with the applicable item definition; wound dressing is not one fixed class. Where the boundary with another product category is uncertain, first establish status using composition and mechanism information.

2. Organize four classification inputs

This table organizes manufacturer answers; it does not automatically assign a class. Use wound descriptions supported by manufacturer instructions and evidence.

An unresolved cell is classification uncertainty. Do not fill it with the class of a visually similar product. When using a comparator, document differences in purpose, material, action and contact.

3. Separate claims from measured facts

An absorption or moisture-related result does not directly establish a shorter wound-healing period. An antimicrobial ingredient or laboratory result also does not automatically support infection treatment. Distinguish what was measured under stated conditions from what is claimed for patients.

Build a claim register linking sales wording, intended use, supporting evidence and unsupported scope. Missing evidence leads to further substantiation or a revised claim. The product listing advertising guide supports wording review after evidence and registration scope have been established.

4. Assess contact by layer and in the finished state

For multilayer products, distinguish possible direct and indirect contact from films, foam, adhesives and coatings. A shared material name does not establish identical additives or process residues. Describe the finished product after manufacturing, cleaning and sterilization as it contacts the body.

Do not simplify wound contact into intact-skin contact. Adhesive on surrounding skin can have a different contact condition from the wound-facing layer. Align duration and repeated use with the instructions and pass those inputs into biological evaluation. Actual risks and applicable Korean criteria determine the evaluation and testing needed.

5. Connect sterilization, packaging and shelf life

Consider whether absorption and adhesion remain supported after storage. Check that shelf-life evidence represents the actual material, size, sterilization and packaging combination. Evidence from a different package needs a justified bridge.

A larger model may change more than area: review sterilization, packaging space, folding and adhesive structure. This does not mean every change needs identical additional tests. Separate affected and unaffected attributes and document what existing evidence can support.

6. Feed classification decisions into test orders

A useful review record includes product description, candidate categories and reasoning, resolved and unresolved questions, and the evidence list by claim. Before ordering tests, reconcile intended use, contact and finished-product condition across specifications and instructions. Ordering a test bundle while classification remains uncertain can force later changes in samples or scope.

Bring a cross-section, layer materials, instructions and proposed claims to request a wound dressing classification review. Clare Partners can organize the questions and evidence sequence needed for the assessment.
