D1 Certificate
Used for managing imported inputs required for export products under the conditional exemption system. Import, production, export, and closure steps must be carried out in line with certificate commitments.

Inward Processing Certificate Services D1/D3
End-to-end management of application, implementation, import, delivery, and closure steps for inward processing processes in energy storage, battery manufacturing, and storage-integrated wind/solar investments.
Inward Processing Approach
When structured correctly, inward processing is not only a certificate; it is a strategic cost tool connecting production, import, investment incentives, and delivery processes.
The Inward Processing Regime enables raw materials, auxiliary materials, semi-finished goods, packaging, and similar inputs required for export production to be procured under defined conditions with customs duty and trade policy measure advantages. The purpose is to help manufacturers reduce global cost pressure and strengthen competitiveness.
At SYDH Consulting, we manage D1 and D3 certificate processes not only as application files, but together with investment incentive certificates, import planning, HS code analysis, bills of materials, waste ratios, delivery scenarios, certificate revisions, and closure management. In battery and energy storage manufacturing, an incorrectly structured certificate can directly affect import costs, delivery planning, and incentive compliance.
D3 Certificate
Issued for sales and deliveries deemed as export. It is a critical tool for structuring customs-exempt supply flows in certain domestic investment and delivery processes.
Energy Storage Application
For battery and energy storage manufacturers delivering to storage-integrated wind/solar investment incentive projects, tax, exemption, documentation, and compliance flows must be designed together.
What Is a D1 Certificate?
D1 is an inward processing permit certificate used to manage imported inputs for export-oriented production under the conditional exemption system.
A D1 Inward Processing Permit Certificate is used by manufacturers operating under an export commitment. The company imports inputs under the certificate, uses them in production, and exports the processed product in line with certificate terms. This structure allows customs duties, trade policy measures, and similar import costs to be managed within certificate conditions.
In a D1 process, correct capacity, consumption, waste ratio, HS code, imported input-export product linkage, and closure calculation are decisive. In multi-component energy storage systems, cells, modules, BMS, PCS, cabinets, cabling, electronic cards, auxiliary equipment, and packaging inputs must be planned consistently with the production bill of materials.
D1 / D3Import • Production • Delivery • Incentive • Closure
- Analysis of HS codes, product descriptions, technical documents, and imported inputs
- Preparation of BOM, consumption, waste, and capacity data according to certificate logic
- Pre-process assessment of customs duty, additional customs duty, surveillance, and VAT effects
- Regular tracking of import declarations, certificate lines, and realization records
- Management of revision, extension, additional time, commitment closure, and risk-control steps
- D3 scenario design for storage-integrated wind/solar deliveries under investment incentives
What Is a D3 Certificate?
D3 enables domestic deliveries deemed as export to be managed under inward processing logic.
A D3 certificate is used for domestic sales and deliveries that are deemed as export under the relevant framework, unlike a classic export flow. This structure is especially important for deliveries to projects with investment incentive certificates, allowing manufacturers to manage imported inputs and production costs more competitively.
For battery and energy storage manufacturers, D3 becomes strategic in equipment deliveries to storage-integrated wind and solar investments. Correctly interpreting customs duty, additional customs duty, surveillance applications, VAT exemption, and related exemption headings in projects with investment incentive certificates creates cost and compliance advantages for both investor and manufacturer.
SYDH Consulting has field experience in implementing this process within the energy storage sector.
For manufacturers supplying storage-integrated wind/solar investments, D3 design should be built together with the investment incentive certificate, import cost, customs duty, surveillance, VAT, additional customs duty, and certificate closure processes. We approach this not as a theoretical document service, but as process management linked to real production and delivery operations.
Critical Topics in Energy Storage and Battery Manufacturing
In energy storage manufacturing, D1/D3 processes affect many decision areas from import costs to investment incentive compliance.
Energy storage systems consist of battery cells, modules, racks, BMS, PCS, EMS, cabinets, fire safety systems, cooling equipment, cabling, and auxiliary components. Because many of these components require import, technical compliance, certification, and customs evaluation, the D1/D3 plan should be prepared before production starts.
For deliveries to buyers with investment incentive certificates in storage-integrated wind/solar projects, it must be clarified from the beginning which inputs will be covered by which certificate, which delivery can be evaluated as a sale deemed as export, which exemptions may apply during import, and which documents will be required during closure.
Tax and Exemption Impact
Customs duty, additional customs duty, VAT, surveillance applications, and trade policy measures are analyzed according to the investment scenario.
Certificate-Operation Fit
Imported inputs, production BOMs, delivery documents, and incentive scope are checked in one flow; certificate lines are kept aligned with operations.
Closure and Risk Management
Commitment closure, missing documents, incorrect HS code, wrong consumption, deadline risk, and revision needs are controlled from the start.
Scope of Work
Within inward processing consulting, the entire process is managed from pre-application to certificate closure.
Pre-Eligibility Analysis
The manufacturing structure, investment/delivery scenario, capacity, product tree, imported inputs, and target delivery model are reviewed.
D1/D3 Certificate Design
Certificate type, imported input list, export/delivery products, consumption, waste, HS codes, and technical document set are prepared.
Incentive and Delivery Integration
Certificate and exemption compatibility is assessed for deliveries to storage-integrated wind/solar projects with investment incentive certificates.
Customs and Import Tracking
Declarations, exemption codes, surveillance, VAT, additional customs duty, and trade policy measures are controlled process by process.
Revision and Time Management
Certificate line changes, additional time, revisions, import/export realizations, and certificate limits are tracked.
Commitment Closure
Import, production, delivery/export documents, and realization calculations are prepared in line with closure file requirements.
Let's plan your D1/D3 process together with your energy storage investment and delivery goals.
For manufacturers supplying storage-integrated wind/solar investment incentive projects, we can evaluate customs duty, surveillance, VAT, additional customs duty, certificate application, implementation, and closure processes together.
