For Indian shipping bills you need 8 digits. These six-digit codes are the international HS 2022. India's ITC(HS) classification (DGFT) and Customs Tariff (CBIC) add two more digits for the national tariff line, so pick the 8-digit line under your 6-digit code there, and confirm with your customs broker for anything borderline.
