Teeth Whitening Products
Teeth whitening products aim to lighten the shade of teeth, removing stains and discoloration. These products vary significantly in their active ingredients, application methods, and effectiveness.
Materials & Active Ingredients:
- Hydrogen Peroxide (H₂O₂): The most common active ingredient, available in varying concentrations. Higher concentrations are generally used by dental professionals, while lower concentrations are found in over-the-counter (OTC) products. It works by breaking down stains into smaller molecules, making them less visible.
- Carbamide Peroxide: Breaks down into hydrogen peroxide, offering a slower release of the whitening agent. Often preferred in take-home kits for sustained release and reduced sensitivity.
- Sodium Perborate: Another peroxide-based compound, less common now due to potential for slower results and irritation.
- PAP (Photoactivated Polymerization): A newer alternative to peroxide-based whitening. Claims to whiten teeth with minimal sensitivity, though long-term efficacy is still under investigation.
- Abrasive Materials: Found in whitening toothpastes, these physically remove surface stains. Examples include hydrated silica and alumina.
Purpose:
- Remove Surface Stains: Caused by foods, drinks (coffee, tea, red wine), tobacco, and certain medications.
- Reduce Intrinsic Stains: Deeper stains within the tooth enamel, often caused by age, trauma, or fluorosis. These are more difficult to remove and may require professional treatment.
- Improve Overall Appearance: Enhance the brightness and whiteness of the smile.
Function:
Whitening products function by one or more of the following mechanisms:
- Oxidation: Peroxides oxidize stains, breaking them down into colorless molecules.
- Physical Abrasion: Abrasive materials physically scrub away surface stains.
- Chemical Breakdown: Certain compounds chemically alter stain molecules.
Usage Scenarios & Types:
- In-Office Whitening (Professional):
- Concentrated Peroxide Gels: Applied by a dentist with protective barriers, often activated by light or laser. Provides the fastest and most dramatic results. (e.g., Zoom!, Opalescence Boost)
- Laser/Light-Activated Whitening: Uses light energy to accelerate the whitening process.
- Take-Home Kits (Professional/OTC):
- Custom Trays: Dentist-fitted trays used with peroxide gel. More effective than generic trays due to better fit and gel contact.
- Pre-Filled Trays: OTC trays pre-filled with peroxide gel. Convenient but less effective than custom trays.
- Whitening Strips: Thin, flexible strips coated with peroxide gel. Applied directly to teeth for a specified period. (e.g., Crest Whitestrips)
- Over-the-Counter (OTC) Products:
- Whitening Toothpastes: Contain abrasive materials and/or low concentrations of peroxide. Primarily remove surface stains.
- Whitening Mouthwashes: Contain low concentrations of peroxide. Limited whitening effect.
- Whitening Pens: Contain peroxide gel for targeted application. Less effective for overall whitening.
Common Types (further breakdown):
- Gel-Based Systems: Most common, utilizing peroxide gels in varying concentrations.
- Strip-Based Systems: Convenient and relatively affordable, but may not cover all tooth surfaces effectively.
- LED Whitening Kits: Combine peroxide gel with LED light to accelerate the process; efficacy varies.
- PAP Whitening Systems: Emerging technology utilizing photoactivated polymerization; often marketed for sensitivity-free whitening.
Important Considerations:
- Sensitivity: A common side effect, especially with higher concentrations of peroxide.
- Gum Irritation: Can occur if the whitening agent comes into contact with gum tissue.
- Enamel Damage: Overuse of high-concentration products can potentially damage enamel.
- Not Effective on All Stains: May not be effective on stains caused by certain medications or trauma.
- Dental Restorations: Whitening products do not whiten fillings, crowns, or veneers.
- Consult a Dentist: It is recommended to consult a dentist before using any teeth whitening product, especially if you have sensitive teeth, gum disease, or dental restorations.

Here are the relevant HS codes based on the provided reference material:
-
3306900000: This HS code covers preparations for oral or dental hygiene, including denture fixative pastes and powders, and yarn used to clean between the teeth (dental floss) in individual retail packages. This is the most applicable code for teeth whitening products as they are used for dental hygiene.
- 33: Chapter 33 covers essential oils and resinoids, perfumery, cosmetic or toilet preparations.
- 06: Heading 3306 specifically covers preparations for oral or dental hygiene.
- 900000: This subheading covers "Other" preparations within the heading, encompassing a wide range of oral hygiene products not specifically listed.
-
3003900190: This HS code covers medicaments (excluding goods of heading 3002, 3005 or 3006) consisting of two or more constituents which have been mixed together for therapeutic or prophylactic uses, not put up in measured doses or in forms or packings for retail sale. If the teeth whitening product is formulated as a medicament with multiple constituents and is not pre-packaged for retail, this code may be applicable.
- 30: Chapter 30 covers pharmaceutical products.
- 03: Heading 3003 covers medicaments.
- 900190: This subheading covers "Other" medicaments not specifically listed.
-
3005905090: This HS code covers wadding, gauze, bandages and similar articles (for example, dressings, adhesive plasters, poultices), impregnated or coated with pharmaceutical substances or put up in forms or packings for retail sale for medical, surgical, dental or veterinary purposes. If the teeth whitening product is in the form of a medicated dressing or patch for dental use, this code may be applicable.
- 30: Chapter 30 covers pharmaceutical products.
- 05: Heading 3005 covers wadding, gauze, bandages and similar articles.
- 905090: This subheading covers "Other" articles within the heading.
Tax Rate Information:
- 3306900000: Basic tariff: 0.0%, Additional tariff: 25.0%, Additional tariff after 2025.4.2: 30.0%, Total tariff: 55.0%.
