HS Code 50030000
Silk waste (including cocoons unsuitable for reeling, yarn waste and garnetted
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 50030000 would be approximately BDT 64,250.00, because the Total Tax Incidence is 64.25% of the assessable value.
What these figures mean
Silk waste (including cocoons unsuitable for reeling, yarn waste and garnetted is classified under HS code 50030000, which sits in heading 5003 (Silk waste (including cocoons unsuitable for reeling, yarn waste and garnetted stock)) of chapter 50 (Silk).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 25%, Supplementary Duty of 0%, VAT of 15%, Advance Income Tax of 5%, Regulatory Duty of 5% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 64.25%, which is the figure to multiply by the assessable value of your consignment.
The assessable value is normally the CIF value of the goods plus landing charges. Duties and taxes are applied in a defined order rather than simply added together, which is why the TTI is not the plain sum of the individual rates.
Recorded imports
Between December 2025 and May 2026, NBR recorded commercial imports under 50030000 in 6 of 6 months, totalling 41,600 kg at an assessable value of BDT 6,861,394. That is an average of BDT 165 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 2,842nd largest of 4,066 tariff lines by assessable value.
