Bonded warehouses: how exporters avoid 80% duty on their inputs

Bangladesh's ready-made garment industry imports fabric that the published tariff taxes at up to 80%, converts it into garments the tariff taxes at over 100%, and exports the result profitably. That only works because most of those inputs never pay the published rate.

The mechanism is the bonded warehouse. It is the most commercially significant duty facility in the country, and it explains why the figures on this site — which are the ordinary published rates — look impossible against what the export sector actually pays.

The problem it solves

Consider an exporter making shirts. Looking at the published tariff for the inputs:

• Cotton fabric, chapter 52 — 124 lines, ranging 12.5% to 80.18%, averaging 60.90%
• Man-made filament fabric, chapter 54 — 17.88% to 80.18%, averaging 53.50%
• Knitted fabric, chapter 60 — 53.23% to 80.18%, averaging 79.23%
• Trimmings and made-up articles, chapter 63 — averaging 83.85%

Paying 60 to 80% duty on inputs that will leave the country as exports would make Bangladeshi garments uncompetitive immediately. No exporter can absorb that and no export market will pay it.

The underlying principle, applied in every major exporting economy, is that a country should not tax its own exports through the back door. Import duty is a protective instrument for the domestic market. Goods that are going straight back out were never in that market.

How a bonded warehouse works

A bonded warehouse is premises licensed by customs where imported goods are held without duty and tax being paid at import. The liability is not cancelled at the border; it is suspended, and secured by a bond.

The sequence for a bonded manufacturer:

1. Licence. The manufacturer obtains a bonded warehouse licence from customs, tied to specific premises and a specific production capacity.
2. Entitlement. Customs approves an annual entitlement — how much of each input the factory may import duty-free, calculated from its capacity and its input-output coefficients.
3. Import under bond. Inputs enter without payment of duty and taxes and are recorded against the bond.
4. Manufacture. The inputs are consumed in producing goods for export.
5. Export and reconciliation. Exports are documented, the consumption is reconciled against the entitlement, and the corresponding bond liability is discharged.

The facility is normally available to export-oriented manufacturers, including those in export processing zones and economic zones. Whether a specific operation qualifies, and on what terms, is determined by the National Board of Revenue under the governing rules and SROs — it is not something a trader can assume.

The input-output coefficient

The technical heart of the system, and the part that causes most difficulty.

Customs must know how much input is legitimately needed per unit of output — so many metres of fabric per shirt, so many buttons, so much thread, plus an allowance for wastage. That ratio is the input-output coefficient, and it governs the entitlement.

Set it too low and you cannot import enough to fulfil your orders. Set it too high and you have unexplained surplus, which is precisely what customs scrutiny is designed to detect. Getting the coefficient right, and updating it when your product mix changes, is an ongoing exercise rather than a one-time registration.

Where the liability bites: diversion

Bonded goods carry a condition: they must be used for export production. If they are sold into the domestic market instead, the suspended duty becomes payable — with penalties, and often across the whole quantity rather than the portion diverted.

The commercial temptation is obvious when you look at the numbers. Fabric imported under bond at zero cost, sold domestically where the published rate would have been 80.18%, is an immediate and substantial margin. This is why bonded operations are audited, why stock registers and consumption records are mandatory, and why the reconciliation process is demanding.

For a legitimate operator the practical point is administrative: the facility's value is entirely dependent on your records. A factory that cannot reconcile inputs to exports has a liability it cannot discharge, regardless of whether anything was actually diverted.

Why the tariff ladder still matters to exporters

A bonded manufacturer might reasonably ask why the published rates matter at all. Three reasons.

Anything outside the entitlement pays full rate. Overage, unapproved inputs, machinery spares not covered by the bond — all are ordinary imports at the published TTI.

Domestic sales pay full rate. If you sell any part of your production locally, the input duty on that portion crystallises. You need the published figure to price it.

The reconciliation is valued at published rates. Your bond liability, and any shortfall in it, is computed using the ordinary tariff. The numbers on this site are the numbers that appear in that calculation.

There is also the protective structure to understand. The tariff rises steeply from input to finished product — as set out in importing textiles and apparel, chapter 52 fabric averages 60.90% while chapter 62 woven garments average 103.48%. That gradient is what protects domestic garment makers from imported competition, and it is the other half of the same policy the bond facility represents.

Alternatives where bond is not available

Not every exporter qualifies for a bonded warehouse. Two other routes exist in principle: duty drawback, where duty is paid at import and reclaimed after export, and special bonded warehouse arrangements for certain categories of exporter.

Drawback is administratively simpler to enter but much harder on cash flow, since you finance the duty for the whole production and export cycle before recovering it. At the rates involved in textiles, that working-capital cost is not trivial — which is why bond, where available, is strongly preferred.

Before you rely on any of this

This article describes the structure of the facility, not your entitlement to it. Eligibility, licensing conditions, entitlement calculation, permitted input lists and reconciliation requirements are set by the National Board of Revenue and change through SROs and rules — see what an SRO is.

If you are considering a bonded operation, the sequence is: confirm eligibility with the NBR and your C&F agent, establish the licence and entitlement before committing to orders, and build the record-keeping before the first import rather than after the first audit.
