What Qing asks
One dense message. Five is the whole budget per supplier reply, so the questions that decide comparability go first.
- 1.
这批货的性质请明确选择：全新原厂正式版量产件 / 工程样片(ES或QS) / 拆机件 / 翻新件 / 库存尾货。请在PI上以文字写明，不接受口头说明。
State the channel class explicitly on the PI: new production, engineering/qualification sample (ES/QS), pulled, refurbished, or excess stock. Verbal statements are not accepted.
The single most decisive field. New-production, ES/QS, pulled, refurb and remarked all look identical in a photo and differ by multiples in value.
- 2.
到货包装形式是：原厂密封彩盒 / 原厂托盘(tray) / 原厂防静电管 / 通用防静电袋散装？请提供实拍照片，含外箱标签与封条。
How will goods arrive: OEM sealed retail box, OEM tray, OEM anti-static tube, or bulk in generic ESD bags? Send real photos including carton labels and seals.
Original sealed OEM packaging is itself provenance evidence; bulk in generic anti-static bags is not.
- 3.
产品原产地是哪里？能否提供一般原产地证(CO)或优惠原产地证(FORM E / RCEP)？HS编码贵司申报为多少？如产品在第三国完成部分工序，请说明工序与增值比例。
What is the country of origin? Can you issue a general CO or a preferential certificate (FORM E / RCEP)? Which HS code will you declare? If any processing occurs in a third country, describe the operations and the value added.
Origin drives the duty rate and, for some destinations, the trade-remedy exposure. A certificate type (FORM E, RCEP, CO) is a concrete deliverable; 'made in China' is not.
这批货是全新原封、官翻、拆机件还是工程样片(ES/QS)？请在形式发票上写明状态。如果是拆机件，来源和使用时长是多少？
报价是EXW、FOB还是CIF？指定口岸是哪里？报价里不含哪些费用(出口报关、内陆运输、保险、目的港费用)？
外箱尺寸多少？每箱装几台、毛重多少公斤？每托盘几箱？整单总体积多少立方米？是木托还是纸托、是否需要熏蒸证明？
请给出阶梯报价：1台、10台、50台、100台各是什么价格？每个型号的起订量是多少？价格有效期多久？
出口报关准备用哪个HS编码？报价是含税价还是不含税价？该编码的出口退税率是多少、退税是否已经体现在报价里？
整机原产地写哪里？能否出具原产地证(一般CO还是Form E/RCEP优惠证)？货物是从中国直接出口，还是经香港、新加坡或越南转运？
质保多少个月？DOA(到货即损)申报期限是几天？返修是寄回中国还是有海外备件？是否提供先行换货？返修运费谁承担？
这个托架/导轨/面板是原厂件还是兼容件？上面有没有原厂LOGO或型号标识？能否书面保证不侵犯第三方商标和专利，并承担相关责任？
整机和关键部件(CPU、加速卡、网卡)的原产地分别是哪里？产品里有没有使用美国原产的芯片、软件或技术？大概占多少比例？能不能配合签署最终用户和最终用途声明、承诺不转运？这个型号以前出口过哪些国家？
合同和发票的签约主体全称是什么？统一社会信用代码是多少？工厂是自有还是代工？母公司或控股股东是谁、持股比例多少？有没有国资或上市公司背景？
请提供公司全称、统一社会信用代码和营业执照复印件。贵司是生产工厂、原厂授权代理还是贸易商？如为工厂，工厂地址在哪里、可否安排验厂或视频验厂？开票主体与收款主体是否为同一家公司？
最小起订量是多少？请给出阶梯报价（如100/500/1000/5000片）。报价有效期多少天？NAND和HDD价格波动时如何调价？是否接受锁价？

How buyers get burned here
Category-specific, from research rather than generic advice
- Cooling sized at 25 °C, not at your real ambient. Chinese vendors habitually publish nominal cooling capacity at benign conditions. A DX in-row unit rated 40 kW at 35 °C outdoor may deliver 26–30 kW at 48 °C in the Gulf, and its condenser may trip on high pressure entirely. Demand the capacity table at YOUR site design ambient (dry bulb and wet bulb, 0.4% ASHRAE annual percentile), and make the derated figure the contractual number.
- 'IP55' that is IP55 only on the shell. Aipu-Waton's own literature confirms IP65 is a customisation, not a default. Louvres, cable entries, condenser openings and door seals are where ingress actually happens. In sandstorm or coastal environments specify the filtration class (G4/F7), the coating system (C5-M per ISO 12944 for marine), and require an ingress test report on the assembled unit, not a component certificate.
- No UL 2755 certification for a North American destination. UL 2755:2025 is the Outline of Investigation that US and Canadian AHJs now reference for prefabricated modular data centre systems. Almost no Chinese factory holds it as standard, and obtaining it retrospectively means factory inspection plus rework. Ask for the certificate number and the certifying body (UL Solutions, Intertek or CSA) before, not after, the PO.
- Component CE certificates presented as an assembly CE mark. There is no unitary CE mark for a modular data centre. What is required is a technical file combining LVD, EMC, Machinery Directive (for moving parts), pressure equipment (for the cooling circuit), and construction product evidence for the enclosure, plus a Declaration of Conformity naming the assembly. A folder of supplier CE certificates for the UPS and the AC unit is not that.
- Standards mismatch that voids your local design code. GB 50174-2017 explicitly excludes outdoor container-based facilities from its scope. If a supplier cites GB 50174 compliance for a container product, they are citing the wrong standard — the applicable Chinese document is GB/T 36448-2018, with GB/T 1413 and GB/T 5338 for the box itself. Neither maps cleanly onto EN 50600 or the Uptime Institute Tier system, and a container is very hard to certify as Tier III concurrently maintainable.
- Rated payload exceeded, silently. A 40HQ has a rated payload around 26–28 t. A fully fitted 40ft data centre with racks, UPS, batteries, transformer and a filled liquid loop routinely exceeds it. The unit then cannot be stowed as ordinary FCL, cannot be lifted by standard terminal equipment, and cannot legally travel on many roads. Get the weight certificate — dry, and wet-and-populated — in writing before booking freight.
- Out-of-gauge cargo discovered after signing. Anything wider than 2438 mm or taller than 2896 mm is out-of-gauge: flat-rack or breakbulk stowage, special handling, route survey, escorts and permits. Huawei's FusionDC1000B core module at 3600 mm high is already in this category. On difficult inland routes the freight and permit cost can approach the module price. Establish the transport envelope before the technical spec is frozen.
