Can I import an inverter board as a spare part without a certificate?

If the board is not on Uzbekistan's current mandatory certification list for its HS code, a notification/rejection letter is issued instead — standard practice for components. For Kazakhstan the analogue is a rejection letter under TR CU. The lists are updated, so we re-check every shipment.

Who pays VAT and duty?

The importer of record in the destination country, at customs clearance. We quote on terms agreed in the contract (usually FOB/EXW for Kazakhstan; for Uzbekistan by agreement, DAP possible for specific projects).

What documents do you provide for customs?

Invoice, packing list, certificate of origin (FORM A / CCPIT), factory test reports, technical description with HS code. For certifiable items — full document set; for declaration/certificate the applicant must be your resident entity.

How fast is urgent delivery?

Air 5–8 days from payment to Tashkent/Almaty. Truck cargo 12–18 days is optimal for maintenance kits; rail container 30–45 days for planned volumes. In winter the rail route can stretch to 60 days (Khorgos reload congestion).

Do you work with Russia?

Certification rules are the same (EAEU), but payment and logistics channels currently require separate verification. In year one we focus on Uzbekistan and Kazakhstan; Russia — once channels are ready, without active promotion.

Importing Spare Parts into Uzbekistan: Certification & Customs Guide 2026

Uzbekistan is not an EAEU member: its own certification system, tariffs and VAT. This handbook brings together everything a spare-parts importer needs: HS codes, documents, clearance steps and shipping timelines from China. Based on 2026 regulations.

IGBT modules	8541 29 / 8541 30	0–10%	not on the mandatory list*	rejection letter*
Control boards (inverters)	8538 90 000 0	0–10%	RoHS check 2026*	rejection letter / declaration*
Cooling fans	8414 59 9050 / 99	0–10%	generally no*	declaration

* Asterisked items require per-SKU confirmation against the current Uzstandard list at shipment date; rates per PP-3818 (lex.uz). For planning purposes, not a substitute for customs declaration.

Step-by-step import into Uzbekistan

1. HS code classification

The exact 10-digit line determines both the tariff and whether the item falls under mandatory certification. One wrong digit means a wrong rate and a risk of retroactive charges. Before the first shipment we obtain an advance classification ruling (free in China via the “Internet + Customs” service).

2. Checking the Uzstandard list

Uzbekistan (not an EAEU member) maintains its own list of products subject to mandatory certification — by HS code, updated annually. If an item is not on the list, a notification/rejection letter is issued instead of a certificate.

3. RoHS check (from 2026-02-17)

Uzbekistan’s technical regulation restricting hazardous substances in electrical and radio-electronic equipment entered into force on 17 February 2026. For boards and power electronics, coverage requires written confirmation — we verify it for every shipment.

4. Contract, invoice, packing list

The baseline document set for customs. We declare real specifications and HS codes; consistency between the invoice and the actual shipment is a mandatory condition for smooth release.

5. Payment and taxes

Import VAT 12% + customs duty by category (0–10% for most of our items). Payment in USD or CNY is possible — we confirm with the importer’s bank in advance.

6. Logistics and release

Air freight 5–8 days for urgent items, truck cargo 12–18 days, rail container 30–45 days (up to 60 days in winter due to reloading at Khorgos). We issue a tracking number on the second day after payment.

Kazakhstan (EAEU): key differences

Only an EAEU resident can be the certificate applicant

A TR CU certificate of conformity cannot be issued to a Chinese supplier or to us as the exporter. The scheme: you (the importer in Kazakhstan) are the applicant; we provide factory test reports, technical documentation and Russian-language descriptions, and secure the manufacturer’s support for the audit.

Certificate vs Declaration vs rejection letter

Circuit breakers (8536 20) are on the TR CU 004 list — a certificate or declaration is required depending on the item. Components (IGBT modules, boards as parts) usually go with a rejection letter. Discrete items — per the annex to the regulation.

Batch certificate 4D/3C

Tied to the contract and invoice: one batch — one certificate. For regular shipments a series certificate (up to 5 years) is more cost-effective, but it requires samples and a factory audit.

New units only

TR CU 004/2011 explicitly excludes used equipment. Refurbished boards are illegal to import into the EAEU — consistent with our zero-tolerance policy on grey boards.
