Scented card

The base material is critical for scent retention and aesthetic appeal. You should prioritize high-density absorbent paper or cotton linter board with a thickness of at least 1.5mm to 2.0mm to prevent warping. Ensure the paper is acid-free and FSC-certified to meet environmental standards and prevent the fragrance from reacting with the paper chemicals, which could alter the scent profile.

Request detailed information on the fragrance oil concentration, which should ideally be between 15% to 25% for long-lasting effects. Ask suppliers for MSDS (Material Safety Data Sheets) and IFRA (International Fragrance Association) compliance certificates to ensure the oils are safe for inhalation. A high-quality scented card should maintain a noticeable aroma for 30 to 60 days when kept in a standard environment like a car or closet.

For branding, offset UV printing is recommended for vibrant colors and sharp details, while silk-screen printing is better for simpler logos on textured surfaces. To enhance the premium feel, consider debossing, foil stamping, or die-cutting into custom shapes. Ensure the supplier uses soy-based or eco-friendly inks that do not interfere with the fragrance release.

For the US market, products must comply with California Proposition 65 regarding chemical exposure. For the EU, REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) and CLP (Classification, Labelling and Packaging) regulations are mandatory. Always verify that the packaging includes warning labels and ingredient lists in the local language of the destination country.

The biggest risk is scent loss or cross-contamination. Ensure each card is individually heat-sealed in high-barrier OPP or aluminum foil bags. For bulk transport, use double-walled corrugated cartons and request cool-chain logistics or avoid top-deck stowage on vessels to prevent high-temperature exposure which accelerates oil leakage and evaporation.

Focus on the unit price vs. fragrance longevity trade-off. Negotiate for tiered pricing where the price drops significantly at the 5,000 and 10,000 unit marks. Additionally, request free plate-making or mold fees for long-term contracts. You can also negotiate for extra scent-booster packaging or a 2% overage to account for potential packaging leaks during transit.

Utilize the secured payment services on Made-in-China.com to protect your funds until delivery is confirmed. Before placing a large order, conduct a factory audit or hire a third-party inspector to verify the supplier's ISO 9001 certification and their capacity to handle volatile organic compounds (VOCs) safely. Always request a pre-production sample (PPS) for scent and color approval.

Since scented cards contain essential oils, some customs authorities may classify them as 'sensitive goods'. Ensure your supplier provides a Non-Hazardous Cargo Declaration and the correct HS Code (typically 330749). For shipping to the US or Europe, clarify the Incoterms (FOB is recommended) to maintain control over the freight forwarder who has experience handling scented or chemical-based items.
