The most critical component is the absorbent paper stock, typically ranging from 1.5mm to 2.0mm in thickness. You should prioritize high-density cotton paper or specialized blotting paper that is acid-free to prevent the fragrance from oxidizing or changing scent profiles. Ensure the paper has a high absorption rate to hold at least 2-5ml of fragrance oil without warping or leaking.
To guarantee a shelf life of 6 to 12 months, the cards must be sealed in high-barrier packaging, such as OPP bags with a header or aluminum foil composite bags. The fragrance concentration should be 15% to 25% (Parfum grade). Ask suppliers for encapsulation technology options, which allow the scent to be released slowly over 20 to 45 days once the package is opened.
For B2B branding, offset UV printing is preferred for vibrant colors that won't bleed when in contact with fragrance oils. If your design includes metallic elements, use hot foil stamping, but ensure the supplier uses oil-resistant foil. For complex shapes, request precision die-cutting with a tolerance of ±0.5mm to ensure brand consistency across large batches.
Suppliers must provide MSDS (Material Safety Data Sheet) for the fragrance oils used. For the US market, compliance with IFRA (International Fragrance Association) standards and California Proposition 65 is essential. For the EU, ensure the product meets REACH regulations and that all allergens are clearly labeled if required by the destination country's cosmetic or household product laws.
Fragrance cards are classified as sensitive cargo due to the liquid fragrance content. You must ensure the supplier provides a Certificate for Safe Transport of Chemical Goods. For air freight, the scent must be double-sealed to prevent odor leakage, which can lead to airline rejection. Sea freight is more economical for bulk orders, but ensure the container is kept away from heat sources to prevent scent degradation.
Always request a pre-production sample (PPS) infused with your specific scent choice. Use Made-in-China.com's Secured Trading services to protect your payment until the third-party inspection confirms the scent accuracy and vacuum-seal integrity. Negotiate a defect rate clause of less than 1%, as packaging leaks are the most common issue in mass production.
Verify the supplier's Business License and Export Qualification on the Made-in-China.com platform. Look for Audited Suppliers who have undergone on-site inspections by SGS or TÜV Rheinland. Avoid paying via private accounts; always use official corporate bank accounts or the platform's integrated payment systems to ensure a traceable paper trail for customs and tax purposes.
