Label kualitas merupakan salah satu atribut produk yang dianggap penting dalam proses keputusan pembelian. Meski demikian, studi mengenai peran label kualitas masih jarang dilakukan dan beberapa temuan menghasilkan temuan yang kontradiktif. Untuk mengisi kesenjangan yang ada dalam literatur, penelitian ini bermaksud untuk mengkaji pengaruh label kualitas terhadap sikap konsumen (kualitas produk dan niat membeli) dalam mengambil keputusan pembelian produk, tergantung pada brand familiarity dan keterlibatan produk. Penelitian ini dilakukan dengan 2 studi eksperimen. Desain eksperimen studi 1 yaitu 2 (label kualitas: ada vs tanpa label) x 2 (Brand familliarity : familiar vs unfamiliar) dengan eksperimen between- and within-subject. Partisipan studi 1 diperoleh sebanyak 155 mahasiswa S1 Universitas Indonesia. Sedangkan, desain eksperimen studi 2 yaitu 2 (label kualitas: ada vs tanpa label) x 2 (keterlibatan produk : tinggi vs rendah) dengan eksperimen between- and within-subject. Partisipan studi 2 diperoleh sebanyak 266 mahasiswa S1 Universitas Jendral Soedirman. Hasilnya menunjukan bahwa pengaruh label kualitas terhadap persepsi kualitas produk dan niat membeli produk tergantung pada brand familiarity. Hal yang sama, pengaruh label kualitas terhadap persepsi kualitas produk dan niat membeli produk tergantung pada keterlibatan produk.
