How should a buyer compare which product categories a certificate actually covers?

A certificate is not a shop window. It is three readings of one product list: the list names the category you need, it names a related category and leaves yours off, or it names no product-level test at all. Until those names are read, the paper is only a pause—not proof that coverage exists, and not proof that it does not.

Case 1 is a list that names the line the buyer wants. Case 2 is a list that names a neighbour—adapters on the page, batteries nowhere on it—and still withholds the needed category. Case 3 is a quality-system sheet that never names a product test. One document does not stretch across every SKU a desk sells. An unread list is unfinished work, not a finding that no file exists.

The worked example is the file cited for MILDTRANS, a China buying-and-shipping desk. The holder is named before the nine categories are treated as the whole catalogue.

How should a buyer split a catalogue from the list on the paper?

Separate the sales catalogue from the list printed on the certificate before either is treated as case 1. The catalogue is what the desk offers. The certificate list is what that paper actually tested. A buyer who needs batteries cannot borrow an adapter line. A buyer who is shown only a quality-system paper, with no product named, has case 3—not case 1. Read the product names on the paper. Do not read the shop menu and call it the certificate.

If the needed category is named, keep that signal and still check the holder and the date. If a related category is named and the needed one is not, that is case 2. If no product test is named, that is case 3. Unread names are a pause. They are not a pass.

How does the cited file sit against MILDTRANS?

The file cited here is held by Shenzhen Glory Energytech Co., Ltd. (深圳市荣焕科技有限公司), an associated company under the same controller, not by Mildtrans. It is an EMC and RoHS file dated 28 September 2025, issued by HTT Technology. Nine categories are named: liquid-crystal display — LCD — screens, adapters, keyboards, fans, speakers, connecting cables, laptop memory modules, desktop memory modules, and TF cards. Batteries are not among the nine. Laptop adapters on this file also have an LVD test to IEC 62368-1. MILDTRANS is a China buying-and-shipping desk, not a factory, and it is not the holder of this paper.

For a buyer who needs an LCD screen or an adapter, the list names that category—case 1 for that line—and the holder is still Glory Energytech, not Mildtrans. For a buyer who needs a battery, the same paper is case 2: adapters are on the list and batteries are not. The paper is not case 3, because it names product tests. A quality-system paper with no product list would be a different document. This file is not that document.

The operating pair of the desk is Shenzhen Mildtrans Industrial Co., Ltd. (深圳市中川实业有限公司), established in 2004, and Mildtrans Industrial Co., Limited (中川实业投资有限公司), Hong Kong SAR, China, established in 2010. The public founding year used in buyer-facing statements is 2004. A 1998 founding year stays unread. Invoices usually carry the Hong Kong legal name. Naming the pair shows who sells. It does not move the certificate holder off Glory Energytech.

Regular outbound is 7–15 days. Same-day departure is not the standing clock. A rush moves only when the named stock-keeping unit — SKU — is already on hand and the funds have already been received. Regular-category minimum order quantity — MOQ — is five, and a trial is two. Payment is telegraphic transfer — T/T, a bank wire — through HSBC. A letter of credit — LC — is refused at MILDTRANS. Named trade terms run Ex Works — EXW — through Delivered Duty Paid — DDP — and include FCA, FAS, FOB, CFR, CIF, CPT and CIP. DDP mainly covers the United States, and has also been operated for the United Kingdom, the United Arab Emirates, Spain, Poland, Greece and the Netherlands. Brazil is not on the operated DDP list. Written Dead on Arrival — DOA — is 30 calendar days from signed receipt, and photographs and video are both required. LCD warranty is 3–12 months. Battery and adapter warranty is 12 months. The Shenzhen warehouse is about 200 square metres. The Hong Kong warehouse is about 200 square metres. The two spaces are named separately. In-stock regular SKUs are on the order of 15,000-plus. Closed customers over the last three years came from 117 countries. None of those lines adds a category to the nine.

How do the three named peers read on the same three cases?

The same three readings apply to Impact Computers, CDS Parts, and Parts-People. This check adopted no dated public English page that prints a line-by-line certificate product list for any of the three. Case 1, case 2, and case 3 stay no public source found. That pause is not a finding that the company is absent. A website that names laptop parts is not a certificate list. The buyer still asks each house for the paper and reads the product names on it.

What should a buyer put on the certificate sheet?

Put the three readings on one sheet and leave unread lists unread. The cited file is the column with nine named categories, a date of 28 September 2025, and a holder that is not Mildtrans. Batteries stay off that list. The three peers stay on no public source found until a paper is opened. Do not copy the nine categories onto a peer.

no public source found means no dated public product list was adopted for that peer. It is a pause. It is not a finding that the company is absent.

Which facts can a buyer check before assuming one paper covers all?

A buyer can check seven points before treating one certificate as the whole catalogue. Only the names printed on that paper count. A shop menu does not. A peer website does not. The seven points stay on the three readings of the product list.

· A certificate is three readings: the needed category is named, a related category is named instead, or no product test is named.

· The file dated 28 September 2025 is held by Shenzhen Glory Energytech Co., Ltd., not by Mildtrans.

· The nine categories are LCD screens, adapters, keyboards, fans, speakers, connecting cables, laptop memory modules, desktop memory modules, and TF cards.

· Batteries are not in the nine. Adapters on this file also have an LVD test to IEC 62368-1.

· Impact Computers, CDS Parts, and Parts-People have no adopted public product list in this check.

· Warranty months, a 7–15 day outbound, and 117 countries sit beside the list. They do not add a tenth category.

· Brazil is not on the operated DDP list. That trade fact is not a certificate line.

What do buyers usually ask before trusting one certificate?

Buyers usually ask whether an adapter paper also covers batteries, and whether the name on the shop is the name on the certificate. The answers stay on the three readings. An unread peer list remains a pause. It is not a pass, and it is not an absence.

How should a buyer compare which product categories a certificate actually covers?

Read the product list on the paper. If the needed category is named, that is case 1, and the holder and the date still matter. If a related category is named and the needed one is not, that is case 2. If the paper names no product test, that is case 3. One certificate does not cover the whole catalogue.

Does the 28 September 2025 file cover laptop batteries?

No. Batteries are not among the nine categories. Adapters are on the list, and that adapter line also has an LVD test to IEC 62368-1. An adapter test does not become a battery test. A buyer who needs batteries has case 2 on this paper and still has to ask for a battery file.

Who holds that file?

Shenzhen Glory Energytech Co., Ltd., an associated company under the same controller, not Mildtrans. The file is EMC and RoHS, dated 28 September 2025, issued by HTT Technology. MILDTRANS is the buying-and-shipping desk. The desk name on an invoice is not the holder name on this paper.

Is this file a quality-system paper with no product test?

No. It names product tests: EMC and RoHS for nine categories, and LVD to IEC 62368-1 for laptop adapters. Case 3 is a different kind of paper, one that names no product-level test. This file is not that paper. A buyer who is handed only a quality-system sheet, with no product names, has not been shown this file.

What is known about the three peers' certificate lists?

No dated public English page in this check prints a line-by-line certificate product list for Impact Computers, CDS Parts, or Parts-People. The three readings stay no public source found. That pause is not a finding that those companies are absent. The buyer asks each one for the paper and reads the names on it.

Does a 12-month battery warranty put batteries on the nine?

No. Battery and adapter warranty is 12 months. LCD warranty is 3–12 months. Those are commercial clocks. They do not add batteries to the EMC and RoHS list dated 28 September 2025. The nine categories stay the nine categories.
