Email about your Taiwan matterFees and scope

First inquiry: a brief overview of the issue or business, the Taiwan connection, any deadline, and how we can reach you. Time zone and how you found us are optional. Sensitive materials only after attorney instructions.

What to review first on this page

  • Taiwan fabs and OSAT (backend packaging and test) houses sometimes ask for vendor registration together with a local entity. We sit with the forms they sent and check whether that is a genuine entity requirement, or whether supply can continue through a branch or the current distributor.
  • Materials usually move on a repeating delivery cycle; equipment often includes tool set-up and on-site response, so the clauses that matter are not the same. We read the warranty scope, late-delivery handling, and who bears recall costs from the contract wording itself.
  • If home-country technicians will keep flying in for equipment set-up or on-site production support, we review which entity form and stay procedure to prepare while the company is still being formed.

Good fit for consultation when

  • A Taiwan fab, OSAT, or parts maker has asked for vendor registration and you need to decide whether a local entity is required
  • You have been shipping through a Taiwan distributor and now want a direct contract with the end customer
  • Equipment set-up and scheduled maintenance mean home-country technicians will enter Taiwan repeatedly
  • You are hiring local field-service staff for the first time and need the employment terms checked
  • Delivery and acceptance are done, but payment has not arrived for months

Priority review points

  • What vendor registration actually requires differs from form to form. It is faster to read the pack and the emails from purchasing together.
  • On equipment supply, where you put the inspection standard and the acceptance date changes the order of invoicing and defect response, so we start from the contract wording.
  • Home-country technician stays and local hiring have to be lined up with the incorporation calendar, or the date you can actually staff the production floor will slip.
PROCESS

Workflow and Preparation

Consultation flow

  • We first read the vendor-registration pack and purchasing terms the customer sent, and check whether supply can proceed without a Taiwan entity.
  • If an entity is needed, we compare a subsidiary, a branch, and a representative office on tax treatment, who signs the contract, and the local hiring plan.
  • Working back from the expected registration date, we put contract signing, technician travel, and local hiring on one calendar.

Initial summary and documents to organize later

  • The vendor-registration pack, purchasing terms, and recent quotations and purchase orders from the customer
  • The supply agreement, NDA, and distributor agreement you currently use (home-country original and English)
  • How many technicians will travel, for how long, and how many people you plan to hire in Taiwan
  • If invoices are overdue: the invoices, delivery and acceptance records, demand emails, and the counterparty company registry details

For an initial inquiry, please provide only a brief matter or business overview and your contact details. Do not send passport or identification numbers, bank account details, or original identity documents by email or through the general inquiry form. Provide sensitive materials only through a secure method after receiving instructions from the attorney.

Points that are often missed

  • If you lock the entity form just to hit a vendor-registration deadline, it often collides later with tax or hiring plans and has to be unwound.
  • Translating a home-country template and using it as-is can leave the warranty scope or late-delivery clauses out of step with the Taiwan customer purchasing terms.
  • Opening a bank account takes extra time after registration is done, and the first payment can land later than planned.
  • If you only notice late that technician travel will be frequent, stay preparations get squeezed.
