Compliance steps

1
Obtain a CIB&RC certificate of registration (document code 101dc1) if thiourea is imported for insecticidal use, or an import permit for non-insecticidal use (document code 911ci3) from the Registration Committee under the Department of Agriculture and Co-operation. Import from any source not specified on the certificate or permit is prohibited; upload both documents in e-Sanchit before filing the bill of entry.

2
Where thiourea qualifies as an NDPS substance, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 (document code 9111dc) before shipment. Imports for medical and scientific purposes are governed by Chapter VII-A of the NDPS Rules, 1985; all other NDPS imports are subject to ITC (HS) policy condition 2 of Chapter 29.
Chapter VII-A and Rule 53 of the NDPS Rules, 1985 · ITC (HS) policy condition 2 of Chapter 29
3
Ensure the import declaration includes mandatory additional Chapter 29 qualifiers as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. Where the consignment constitutes a specified hazardous substance imported in excess of notified threshold quantities, obtain a public liability insurance policy under the provisions of the Public Liability Insurance Act, 1991 per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is classifying the end-use as non-insecticidal and filing only the import permit (911ci3), while omitting the mandatory registration certificate (101dc1) where CIB&RC determines the actual use triggers full Insecticides Act registration. CIB&RC may specify the permitted source of import on the certificate or permit, and a change of supplier — even mid-shipment — voids the authorisation and exposes the consignment to seizure and prosecution under the Insecticides Act; confirm the approved source before every purchase order.

Frequently asked

Does HSN 2930 90 11 require BIS certification?

No, thiourea falls outside the BIS Quality Control Order regime; no BIS QCO covers organo-sulphur compounds under Chapter 29. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with NDPS and MEFCC hazardous-substance overlays as applicable.

Which e-Sanchit document codes are mandatory at the bill of entry for this tariff line?

The mandatory documents are: registration certificate for drugs (101dc1), import licence for drugs (9111dc), and import permit for non-insecticidal use (911ci3), whichever apply based on end-use — all must be uploaded in e-Sanchit before customs out-of-charge.

Does the Free ITC (HS) status under DGFT Notification 44/2025-26 remove the CIB&RC and NDPS requirements?

No. The Free import policy status under DGFT Notification 44/2025-26 dated 15-10-2025 affects the ITC (HS) policy channel only; it does not supersede the sectoral PGA obligations under the Insecticides Act, the NDPS Rules, 1985, or the MEFCC public liability insurance requirement.
