A word of counsel

The most common error on this tariff line is treating arsenic trioxide purely as an industrial chemical and overlooking the drug-regulatory document set required at e-Sanchit — including registration certificate (101dc1) and import licence (9111dc). Importers who route consignments without these uploads will face out-of-charge refusal regardless of whether the Chapter 28 qualifiers are correctly filed; both the chemical-compliance and drug-documentation obligations must be satisfied concurrently.
