Fulfillment Center Blind Spots: How US E-Commerce Sellers Are Walking Into India's GST and Duty Enforcement Net

For many US companies, entering the Indian consumer market through an established e-commerce platform feels like the low-friction path. Inventory is warehoused by a third-party logistics provider, orders are fulfilled automatically, and the platform handles much of the customer-facing transaction infrastructure. From a headquarters perspective in Chicago or Seattle, the arrangement looks clean, scalable, and administratively simple.

What it rarely looks like from the perspective of India's tax authorities is another matter entirely.

US sellers operating through Indian fulfillment networks are accumulating GST liabilities, duty exposures, and registration obligations that their platform agreements do not address—and that their domestic accounting teams are not equipped to detect. By the time enforcement correspondence arrives, the exposure has typically compounded across multiple quarters.

Why the "Platform Handles It" Assumption Fails

India's GST framework assigns distinct compliance obligations based on the nature of a seller's participation in a transaction. When a US company ships goods into an Indian fulfillment center operated by a marketplace or third-party logistics provider, that company does not simply hand off its regulatory responsibility. Indian tax law continues to treat the US entity as a supplier for GST purposes, regardless of which party physically manages the inventory.

This distinction matters enormously. Under India's GST rules, sellers who store goods in a state-level warehouse—even through an intermediary—may trigger registration requirements in that specific state. India's GST framework is state-administered at the registration level, meaning that a single national sales strategy routed through fulfillment centers in Maharashtra, Karnataka, and Delhi can create simultaneous multi-state registration obligations that most US sellers have never contemplated.

Platform agreements typically disclaim responsibility for the seller's own GST compliance. The marketplace may collect and remit tax collected at source (TCS) under Section 52 of the CGST Act, but that mechanism does not satisfy the seller's independent registration and filing obligations. These are parallel requirements, not substitutes for one another.

The Inventory Classification Problem

Beyond registration, the manner in which goods are classified when they enter an Indian fulfillment center creates a second layer of exposure. Goods imported into India for eventual consumer sale are subject to customs duties and integrated GST at the point of entry. The applicable rate depends on Harmonized System of Nomenclature (HSN) classification—a system that Indian customs authorities interpret with considerable specificity.

US companies frequently rely on the product descriptions used in their domestic catalog systems when preparing import documentation. Those descriptions do not always map cleanly onto Indian HSN codes, and the misalignment can result in goods being assessed at a lower duty rate than authorities subsequently determine to be correct. When that determination comes months or years after the initial import, the liability includes not only the duty differential but also interest and potential penalties.

Fulfillment center operators are not responsible for the accuracy of a seller's import classifications. Their role is logistics, not customs advisory. The US seller bears full responsibility for classification accuracy, and that responsibility does not diminish because a third party is managing the physical goods.

B2B Supplier Duties Versus B2C Seller Obligations

A structural complexity that catches many US companies off guard involves the distinction between their role as an importer or B2B supplier and their role as a B2C seller through the e-commerce platform. These two functions carry different GST compliance profiles, and they frequently operate simultaneously without the US seller recognizing the distinction.

When goods arrive at an Indian fulfillment center, the US company may be functioning as an importer of record—a role that carries its own GST registration and input tax credit considerations. Once those goods are sold to Indian consumers through the platform, the company transitions into a B2C supplier role subject to a different set of invoicing, reporting, and reconciliation requirements. Indian GST law does not automatically consolidate these obligations; each must be managed according to its own regulatory logic.

For US finance teams accustomed to a single federal sales tax framework, this layered structure is genuinely unfamiliar. The result is that many sellers satisfy one set of obligations while inadvertently neglecting the other—creating gaps that surface during audits or routine departmental reviews by the Goods and Services Tax Network (GSTN).

The Timing Problem: Why Exposure Grows Before It's Noticed

One of the more damaging features of this compliance dynamic is its delayed visibility. A US company that launches an Indian storefront in the first quarter of a fiscal year may not receive its first regulatory inquiry until the third or fourth quarter—by which time multiple filing cycles have passed without compliant returns. Interest on unpaid GST in India accrues at 18 percent per annum under Section 50 of the CGST Act, and that rate applies from the original due date regardless of when the seller became aware of the obligation.

This compounding dynamic is why the phrase "months after launch" appears with uncomfortable regularity in the experience of US sellers who contact compliance advisors after the fact. The initial period of apparently smooth operations is not evidence that the compliance architecture is sound. It is often simply the interval before enforcement attention arrives.

Conducting a Pre-Enforcement Audit of Existing Arrangements

US companies that are already operating through Indian e-commerce fulfillment networks should treat a structured compliance review as an immediate priority rather than a deferred project. That review should address several specific areas.

First, confirm whether the company has active GST registrations in every state where its inventory is warehoused. If fulfillment center locations have changed or expanded since launch, registrations may not reflect the current footprint.

Second, review the HSN classifications applied at the time of import against the classifications that Indian customs authorities would be expected to apply on examination. Where discrepancies exist, assess whether voluntary disclosure or reclassification is advisable before an audit compels that determination.

Third, reconcile the TCS amounts remitted by the platform against the company's own GST filing obligations to confirm that the two streams are being reported consistently within the GSTN system. Discrepancies between platform-reported data and seller-reported data are a known audit trigger.

Fourth, review the terms of the fulfillment and logistics agreements to identify any provisions that allocate compliance responsibility in ways that may conflict with Indian statutory obligations—and recognize that contractual allocation does not override regulatory liability.

Acting Before the Notice Arrives

India's e-commerce sector is under increasing scrutiny from GST authorities, who have identified the fulfillment center model as a structural source of compliance leakage. Enforcement activity in this space is not theoretical; it is ongoing and accelerating.

US companies that have entered the Indian market through platform-based fulfillment arrangements have a narrowing window to assess their exposure on their own terms. The alternative—waiting for a show-cause notice or assessment order—forfeits both the ability to manage the narrative and the opportunity to engage India's voluntary compliance mechanisms before formal proceedings begin.

At RajExcise Advisors, we work with US companies at every stage of their Indian market engagement to identify and address the compliance gaps that third-party fulfillment arrangements routinely obscure. The cost of a structured review is a fraction of the liability that accrues when those gaps go unaddressed.
