FAQ

The core logic is "approve the stock and the production formula first, then import duty-free batch by batch, and after the product is exported, write the raw materials off the books according to the production formula." BOI duty-free raw materials are not a single certificate that covers all imports; they are an ongoing, cyclical process of inventory and evidence management.

1. Filing and Reconciliation for Duty-Free Raw Material Imports Can Usually Be Broken Into Four Steps

1. Establish the raw material list and Max Stock. The enterprise first applies for a raw material stock list based on the BOI project's products, capacity, and raw material requirements. BOI's published rules show that Max Stock is used to cap the maximum stock of each type of raw material that can be imported duty-free, and it is approved according to the project's production needs.

2. Establish the production formula. The production formula specifies which raw materials are used per unit of product and in what quantity, and it is the basis for deducting stock and reconciling after the product is exported.

3. Apply for duty-free release batch by batch. Once the base data such as Max Stock and the production formula is approved, the enterprise can apply for duty-free release of each batch of raw materials through RMTS Online, and customs then processes clearance according to the approved data.

4. Adjust stock and reconcile after export. After the product is exported, deduct the corresponding raw material usage based on the export data and the approved production formula, so that the stock quota is restored and cyclical use is formed. Raw materials not used for qualifying export production, which cannot be reasonably reconciled, or which must be disposed of under the rules, should go through duty payment, disposal, or other procedures in accordance with BOI regulations.

2. The Most Common Error in Managing Duty-Free Raw Material Imports Is That the Four Data Sets - Name, Formula, Stock, and Export - Do Not Match

For example, head-office ERP splits the same raw material into several names by supplier while RMTS has only one master name; the process was changed but the production formula was not; the purchased quantity exceeds Max Stock; export declaration data does not enter the reconciliation chain in time. A single error may look minor, but as batches accumulate it creates a large unreconciled balance, affecting later import quotas and tax treatment.

So raw material management cannot be left to the customs declarant alone. It is connected at the same time to procurement, production, warehouse, customs, BOI, accounting, and audit.

3. Zhongxin's Differentiated Solution: Putting RMTS, Bookkeeping, and Audit on the Same Chain of Evidence

Zhongxin has registered entities, practicing qualifications, and offices in both China and Thailand. The China-side team understands head-office ERP, material codes, and procurement processes; the Thailand-side BOI team handles RMTS rules and execution, while the accountant and auditor teams connect imports, inventory, costs, and financial records.

The value of this setup is that it does not merely "release" one shipment, but continuously checks whether the BOI system quantity, warehouse quantity, financial inventory, and export reconciliation are consistent. Many single-point service providers in the market cover only one segment, either filing or customs clearance, whereas Zhongxin is better suited to managing this as a long-term compliance process.

4. How Zhongxin's Compliance Growth CODE Model Is Applied in Raw Material Management

5. Professional Basis and Scope of Services

Whether specific raw materials fall within BOI's duty-free scope, the Max Stock quantity, the production formula, and the reconciliation method are all governed by your promotion certificate, the BOI approval results, and the RMTS rules in force at the time. Zhongxin can take on the raw material list, the production formula, RMTS operations, and ongoing reconciliation management, and connect them with Thai bookkeeping and audit data; the actual logistics and customs clearance are carried out by the client or the relevant professional institutions.

Next Step: Apply for a Compliance Review of RMTS Raw Materials

If your company has already started importing raw materials or is about to begin production, there is no need to organize the complete historical documents first. Provide the four pieces of information, and Zhongxin can make a preliminary judgment on whether the priority right now is to check Max Stock, the production formula, the release, or the reconciliation.

Component name: [Application for a Compliance Review of RMTS Raw Materials]

Applicable clients: Chinese enterprises that have obtained the BOI certificate and are now entering the execution stage for equipment, raw materials, capital, or project changes.

Completion principle: fill in only the key information; complex documents are not required. Zhongxin will prioritize its follow-up review around the milestones that need to be confirmed.

Zhongxin will focus its communication on the key information above and will not collect complex documents again. You only need to leave your contact details: contact person, mobile phone or WeChat.

Component handover path: four pieces of information → judgment of RMTS milestones → review by the China and Thailand teams → stock, formula, and reconciliation check → follow-up managed-service plan

Professional note: this component is intended only for a preliminary review of the project situation and does not constitute a BOI approval, tax, or legal conclusion; specific matters are subject to the enterprise's documents, the promotion certificate, and the rules of the competent authorities in force at the time, and should be reviewed by professionals.
