Frequently Asked Questions

What HS codes apply to your pipe fittings?

Carbon steel flanges are classified under HS 7307.91 and stainless steel flanges under HS 7307.21. Carbon steel butt-weld elbows and tees fall under HS 7307.93, and stainless steel butt-weld fittings under HS 7307.23. The applicable code is stated on every quotation and on the commercial invoice. Classification is confirmed by customs at destination.

What documents come with every shipment?

A certificate of origin is issued on request, and a fumigation certificate is provided when wooden packaging is used. Third-party inspection (SGS, Bureau Veritas or an inspector you nominate) can be arranged before shipment.

What is the import duty on pipe fittings in Oman and the UAE?

Oman applies the GCC Common External Tariff of 5% on the CIF value for steel pipe fittings under HS 7307, plus 5% VAT — approximately 10.25% of the CIF value in total. The UAE applies the same GCC 5% tariff and 5% VAT. Since January 2026 customs declarations in Oman are filed electronically through the Bayan (e-Bayan) system; in the UAE, declarations are filed through Dubai Customs or the relevant emirate portal.

If your broker needs a document in a particular format, tell us before shipment and we will issue it accordingly.

Yes. A certificate of origin is issued with the shipment on request. Chamber of commerce attestation (China Council for the Promotion of International Trade) and embassy legalisation can be arranged; both involve an additional fee and extra processing time, so please confirm the requirement at order stage.
