For imported 2-propanol (IPA, CAS 67-63-0; ITC HS 2905 12 20), the landed cost of IPA in India: BCD, SWS, IGST and the three published total-rate figures is determined by a statutory cascade rather than a single tariff line. The material is a water-miscible, Class 3 flammable solvent with a closed-cup flash point of 12 °C and a boiling point of 82.5 °C at 101.3 kPa. Indian import records typically classify the product under Chapter 29, heading 29.05, subheading 2905 12, with the tariff item for propan-2-ol commonly declared as 2905 12 20. The import declaration requires the transaction value method under Section 14 of the Customs Act, 1962, read with the Customs Valuation (Determination of Value of Imported Goods) Rules, 2007. For a standard bulk consignment, the assessable value is the CIF value in Indian rupees, including ocean freight and marine insurance; terminal handling, container cleaning, customs broker fees, and internal transportation are not part of the statutory value but remain part of the physical landed cost.

The statutory levy sequence on the assessable value consists of Basic Customs Duty, Social Welfare Surcharge, and Integrated GST. The standard Indian tariff treatment widely reported for HS 2905 12 20 applies BCD at 10%, SWS at 10% of BCD, and IGST at 18% of the cumulative value comprising assessable value, BCD, and SWS. The total effective rate is therefore not the simple arithmetic sum of 10%, 1%, and 18%. The IGST base is inflated by the prior BCD and SWS charges. On a CIF value of INR 1,000,000, BCD is INR 100,000, SWS is INR 10,000, and IGST is 18% of INR 1,110,000, or INR 199,800. Total statutory duty is INR 309,800, equivalent to 30.98% of CIF. The frequently quoted simple total of 29% understates the effective rate by 1.98 percentage points.

The three published total-rate figures of 24.49%, 27.74%, and 30.98% arise when the BCD is 5%, 7.5%, and 10% respectively, with SWS and IGST held constant. These figures are not three parallel statutory duties; they are computed effective totals recorded in Indian import data platforms and logistics documentation when preferential or alternate BCD notifications change the first levy. Where the standard BCD of 10% applies, the effective duty stack is 30.98% of CIF. Where a preferential notification reduces BCD, the effective total-rate falls even though SWS remains 10% of the reduced BCD and IGST remains 18% on the reduced compound base.

If the importer is GST-registered and uses 2-propanol for taxable output supplies, the IGST paid at import is available as input tax credit under Section 16 of the Central Goods and Services Tax Act, 2017, subject to matching, possession of the bill of entry, and receipt of goods. In that case, IGST is a working-capital charge rather than a final product cost. BCD and SWS are not creditable and remain embedded in the product cost. For an unregistered, exempt, or composition-scheme importer, the entire IGST is a final cost. This distinction changes the practical landed-cost treatment even though the published statutory total-rate remains identical at the border.

What Produces the Three Published Total-Rate Figures for 2-Propanol Imports?

The cascading base for IGST is the central reason the total-rate figures exceed the visible headline BCD. Under the proviso to Section 5(1) of the Integrated Goods and Services Tax Act, 2017, IGST on imported goods is levied on the value determined under the Customs Tariff Act, 1975, plus BCD and SWS. Because the IGST base includes BCD and SWS, the effective IGST relative to CIF is higher than 18%. In the standard BCD 10% case, the effective IGST contribution is 19.98% of CIF. The SWS is imposed under Section 110 of the Finance Act, 2018, at 10% of BCD. The resulting total is therefore the sum of BCD at 10%, SWS at 1%, and IGST at 19.98% on the CIF-equivalent basis, giving 30.98%.

Published duty records for HS 2905 12 20 sometimes display all three effective rates because different tariff treatments, notification references, or data-clearing rules may apply a BCD of 5%, 7.5%, or 10% before the same SWS and IGST mechanics. The importer must verify the country-of-origin, the specific notification covering the tariff line, and the tariff elimination schedule before accepting a lower published rate. The classification boundary between bulk 2-propanol under 2905 12 20 and formulated disinfectants under Chapter 38 is also commercially significant because the duty and regulatory treatment of a finished sanitizer differs from that of a bulk solvent. An advance ruling under Section 28E of the Customs Act, 1962 may be required where the import is a prepared cleaning formulation rather than a single chemical entity.

The published total-rate figures exclude port demurrage, container detention, customs examination, laboratory testing, storage, drumming, IBC filling, and inland freight from the port to the consuming plant. These actual landed-cost elements are terminal-specific. Published data for demurrage on 2-propanol ISO tank containers at specific Indian ports is limited; the charge must be taken from the relevant port tariff schedule or container freight station invoice. For a conventional bulk movement, the product arrives in 20-ft ISO tank containers or in 200 L drums and 1,000 L IBCs. The tank container handling at Nhava Sheva, Mundra, or Chennai involves additional discharge, safety inspection, and hazardous-cargo documentation. These charges are separate from the three published total-rate figures, which only express the statutory customs duty stack against CIF.

Bulk Receipt, Storage and Creditable-IGST Boundaries

After customs clearance, 2-propanol is received as a flammable liquid under UN 1219, Class 3, Packing Group II. Storage and handling are governed by the Petroleum Act, 1934, and the Static and Mobile Pressure Vessels (Unfired) Rules, 2016, where applicable, in addition to factory inspectorate requirements. The storage tank or transfer system must be grounded and bonded; nitrogen blanketing may be required for high-purity IPA to limit moisture ingress and oxidation. The vapour pressure of approximately 4.4 kPa at 20 °C makes open-air handling impractical where emissions and fire risk must be controlled. A closed-cup flash point of 12 °C imposes flameproof electrical classification and forced ventilation in enclosed drumming and blending areas. Technical-grade 2-propanol is typically purchased against ASTM D770-11(2019), while pharmaceutical and cleaning uses require a certificate of analysis against the relevant Indian Pharmacopoeia, British Pharmacopoeia, or USP monograph.

For pharmaceutical disinfectant production, water content is a critical specification. High-purity and anhydrous-grade IPA can absorb atmospheric water, and pre-drying of distribution containers is required where the water specification must remain below 0.10% w/w during storage. Moisture ingress from humid Indian coastal air at relative humidity above 60% can alter the assay and increase the Karl Fischer water value before blending. Acidic or aldehyde impurities can also affect downstream formulation stability and should be monitored against the pharmacopoeial test limits. The landed-cost calculation for such grades must therefore include quality-retention measures, not only the customs duty stack.

Misclassification of the product as a prepared disinfectant or cleaning agent under Chapter 38 can alter the duty stack and the regulatory documentation. Bulk 2-propanol imported as a single chemical entity should not be declared under a finished sanitizer tariff item unless it has been formulated, dosed, or packaged for retail sale. The distinction is enforced through the bill of entry description, packing list, and certificate of analysis. Where the consignment is a denatured or formulated product, the importer must confirm whether denaturing agents or formulation components move the classification out of 2905 12. This classification control must be completed before the duty calculation because the effective total-rate figure depends on the applicable Chapter 29 tariff item and its notifications.

The integrated GST paid at import is recoverable only when the imported 2-propanol is used in the course or furtherance of business and the output supply is taxable. Input tax credit may be restricted where the product is used for self-consumption, free samples, destroyed goods, or non-business purposes. The importer must maintain a reconciliation between the bill of entry and GSTR-2A/2B to support the credit. BCD and SWS do not enter the electronic credit ledger. The accounting landed cost should therefore separate non-creditable BCD and SWS from creditable IGST. For a CIF value of INR 1,000,000 under the standard 10% BCD scenario, the non-creditable customs burden is INR 110,000, while the creditable IGST is INR 199,800. Any logistics cost from the port gate to the manufacturing site is added after this statutory stack and is also part of the physical landed cost.

The three published total-rate figures are useful for rapid comparison, but they do not replace a consignment-specific landed-cost calculation. The applicable exchange rate is the customs-notified rate on the bill of entry date, not the invoice date. Freight and insurance must be included in the assessable value when the purchase is made on FOB or CFR terms. Port tariff schedules, container freight station charges, tank cleaning charges, and hazardous cargo handling vary by terminal. Published data for these specific terminal charges for 2-propanol is limited and should be obtained from the relevant Indian port or licensed customs broker before shipment. Where the import is intended for a pharmaceutical line, the landed-cost model should also include quarantine testing, pharmacopoeial release, and the cost of holding inventory until certificate of analysis approval is received.
